Which dimensions can create more than one triangle? A. Three angles measuring 75 degrees, 45 degrees, and 60 degrees. B. Three sides measuring 7m, 10m, 12m. C. Three angles measuring 40 degrees, 50 degrees, 60 degrees. D. Three sides measuring 3 cm, 4cm,5cm

Answers

Answer 1

The answer is C

Because the sum of the angles are not up to 180

which makes way for other angles.

Answer 2

Option B, three side lengths measuring 7m, 10m, and 12m can create more than one triangle because there are multiple ways the sides can be oriented to create different internal angles, therefore creating multiple triangles.

The question is about constructing triangles from given dimensions and determining which sets of dimensions can create more than one triangle. In geometry, for a set of dimensions to produce more than one unique triangle, it must not fully determine the shape of the triangle. The axiom that the sum of the angles in a triangle is exactly 180 degrees is key to answering part of this question. Here are the evaluations based on the given options:

A set of angles that sum to 180 degrees will only create one unique triangle.For three given side lengths, as in option B, if they satisfy the triangle inequality theorem (the sum of the lengths of any two sides must be greater than the length of the remaining side), they will create a unique triangle.A set of angles less than 180 degrees does not create a valid triangle.For three given side lengths that form a right triangle (such as a 3-4-5 triangle), if they also satisfy the Pythagorean theorem, they will create a unique triangle.

Upon evaluating the provided dimensions:

Option A: Angles of 75 degrees, 45 degrees, and 60 degrees sum to exactly 180 degrees, forming one unique triangle.Option B: Sides measuring 7m, 10m, 12m can create more than one triangle due to the possibility of different internal angles based on different orientations of the sides.Option C: Angles of 40 degrees, 50 degrees, and 60 degrees only sum to 150 degrees, so no valid triangle can be created.Option D: Sides measuring 3 cm, 4 cm, 5 cm form a unique right triangle, not more than one.

Therefore, the correct answer is B: Three sides measuring 7m, 10m, 12m can create more than one triangle.

Of the 60 students in a school, 24 are currently studying chemistry. Exactly 16 of the girls in the school are not currently studying chemistry. The number of girls in the school is 33. How many boys are currently studying chemistry

Answers

Answer:

7 boys.

Step-by-step explanation:

Given:

Total number of students in the school = 60

Total number of girls in the school = 33

Total number of students currently studying chemistry = 24

Total number of girls not currently studying chemistry = 16

Question asked:

How many boys are currently studying chemistry ?

Solution:

Total number of girls in the school = 33

Total number of girls not currently studying chemistry = 16

Total number of girls currently studying chemistry = Total number of girls in the school - Total number of girls not currently studying chemistry

Total number of girls currently studying chemistry =  33 - 16 = 17                                                  

Now:-

Total number of boys and girls currently studying chemistry = 24

Total number girls currently studying chemistry = 17

Total number of boys currently studying chemistry = Total number of boys and girls currently studying chemistry - Total number girls currently studying chemistry

Total number of boys currently studying chemistry = 24 - 17 = 7

Therefore, 7 boys are currently studying chemistry.

Answer:

AB = 24 cm, BC = 6 cm

Step-by-step explanation:

The perimeter of PQRS = 2(8) + 2(2) = 16 + 4 = 20 cm

Given the perimeter of ABCD is 60 cm, then

scale factor = [tex]\frac{60}{20}[/tex] = 3

That is the dimensions of ABCD are 3 times those of PQRS, so

AB = 3 × 8 cm = 24 cm

BC = 3 × 2 cm = 6 cm

Answer:

AB = 24 cm.

BC =  6 cm.

Step-by-step explanation:

The outer rectangle is a dilation of the inner rectangle centered at the origin. Therefore:

The inner and outer rectangles are similar so the ratio of length to width of the outer rectangle is the same as the ratio of length to width of the inner one.

so AB / BC = 8/2 = 4

AB  = 4BC   -------------(1)

Also as the perimeter  = 60

2AB + 2BC = 60.............(2)

Substituting AB = 4BC in equation (2):

2(4BC) + 2BC = 60

10BC = 60

BC = 6 cm.

and AB = 4*6 = 24 cm.

what’s the coordinate grid ?

Answers

Answer:

linear and lateral

Step-by-step explanation:

thsts it

Final answer:

A coordinate grid, also known as a Cartesian coordinate system, is a mechanism used in mathematics to define every point in a plane with a pair of numerical values indicating horizontal and vertical positions from an origin. Systems like UTM and SPC are derived from this concept, using a grid to simplify plotting and calculations on a plane surface.

Explanation:

A coordinate grid, or a Cartesian coordinate system, is a tool used in mathematics to specify each point uniquely in a plane by a pair of numerical coordinates. These are typically written as an ordered pair (x, y) where 'x' represents the horizontal displacement and 'y' represents the vertical displacement, both measured from a specific origin point. This system of geometry was developed by René Descartes, hence the name Cartesian.

For example, the origin of a coordinate system is the starting point where both x and y are zero, designated as (0,0). If we move to the right, x increases, and if we move up, y increases. Conversely, moving to the left decreases x and moving down decreases y. So, for instance, the point (3,4) is located 3 units to the right of the origin and 4 units above it.

Plane coordinate systems, like the Universal Transverse Mercator (UTM) and the State Plane Coordinate (SPC) systems, simplify calculations by using a grid pattern superimposed on a flattened representation of the Earth's surface, facilitating easier and more precise location plotting than spherical coordinate systems like latitude and longitude.

What is a Circle?

A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the equation of circle be C

Let the center of the circle be represented as A ( h , k )

Now , the radius of the circle is = r units

And , standard form of a circle is

( x - h )² + ( y - k )² = r²

when it is a unit circle , the center is at ( 0 , 0 )

The shape of the distribution of the time required to get an oil change at a 10-minute oil-change facility is unknown. However, records indicate that the mean time for an oil change is 11.4 minutes, and the standard deviation for oil- change time is 3.2 minutes.
(a) To compute probabilities regarding the sample mean using the normal model, what size sample would be required?
(b) What is the probability that a random sample of n=45 oil changes results in a sample mean time of less than 10 minutes?

Answers

Answer:

a) sample size ≥ 30

b) 0.0017

Step-by-step explanation:

a) The central limit theorem states that for population with mean μ and standard deviation σ and take sufficiently large random samples from the population. This will hold provided the sample size is sufficiently large (usually n > 30) for a normal population.

Therefore the sample size should be greater or equal to 30 i.e n ≥ 30.

b) Given that n = 45, μ = 11.4 minutes and σ = 3.2 minutes, the z score (z) is given by the equation:

[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }[/tex]

Substituting values to get:

[tex]z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n} } }= \frac{10-11.4}{\frac{3.2}{\sqrt{45} } }=-2.93[/tex]

Using the z table:

P(x < 10) = P(z < -2.93) = 0.0017

the probability that a random sample of n=45 oil changes results in a sample mean time of less than 10 minutes is 0.0017

Final answer:

For part (a), a sample size larger than 30 would be sufficient for using the normal model. For part (b), we'd use the standard error and z-score to find the corresponding probability for the sample mean time being under 10 minutes with a sample size of 45.

Explanation:

The questions revolve around the normal distribution model, which is a concept in Statistics, and the sample size needed to use the normal model to make inferences about a population (in this case, the duration of oil changes). For part (a), we must note that the Central Limit Theorem allows us to assume the distribution of sample means will approximate a normal distribution if the sample size is large enough (mostly, n > 30 is sufficient).

Thus, for this particular scenario, a sample size greater than 30 would be adequate. For part (b), using the standard error (standard deviation / sqrt(n)) with n = 45, we can find the z score = (X - μ) / standard error, where X is 10. We consult a normal distribution table or use software to find the probability associated with this z-score, which would be the answer.

How do i solve this problem while creating a quadratic equation ?

Answers

Answer:

f(x) = -15x² + 50x

Step-by-step explanation:

You're given the rocket start at ground level, so we can assume,

f(0) = 0

after 1 second the rocket is 35 feet up.

f(1) = 35

and after 2 second the rocket is 40 ft up.

f(2) = 40

Now you have 2 values to  plug in your formula to solve.

Plug in f(x) = ax² + bx + c and solve:

f(0) = a(0)² + b(0) + c = 0

f(1) = a(1)² + b(1) + c = 35

f(2) = a(2)² + b(2) + c = 40

a(0)² + b(0) + c = 0

a(1)² + b(1) + c = 35

a(2)² + b(2) + c = 40

0 + 0 + c = 0   ,   we got c=0, so substitute it

a + b + c = 35

4a + 2b + c = 40

Solve for a and b

c = 0

a + b + 0 = 35

4a + 2b + 0 = 40   , solve it using elimination

-2a - 2b + 0 = -70

4a + 2b + 0 = 40  

2a + 0 = -30

a = -15   , we got a, solve for b now

a + b + 0 = 35

(-15) + b + 0 = 35

b = 50

Now we got c=0, a=-15, and b=50, plug it back in your equation

f(x) = -15x² + 50x + 0

The lifetime of a battery has the exponential distribution with mean 6.9 months. If it fails, I immediately replace it with another – if I have one. I need a year’s supply of the battery. In addition to the one in the flashlight, how many extra should I bring with me? 1, 2, or 3?

Answers

Answer:

You should carry 2 other batteries.

Step-by-step explanation:

If the average life of each battery tends to last 6.9 months, and what you need is a year of battery supply, you probably need to carry two batteries.

The battery inside the flashlight has probably already spent much of its half-life.

We are told that the flashlight already has a battery inside, the batteries are discharged inside the flashlight even if the flashlight is not being used.

Which means that the average life of that battery is wearing out.

It would take 2 more batteries in addition to the one already inside the flashlight to supply the need for these for a year.

A dealer sold a car to a man and made
a propit of 15%. The man then sold it
to a woman for 120,175 at a loss of 5%. How much did the dealer buy the car​

Answers

Answer:

110.000

Step-by-step explanation:

Selling at a loss of 5% means it was sold for 95% of its purchase value.

If 120.175 equals to 95% then 100%(the purchase value) is 126.500.

120.175/95*100 = 126.500 (plenty of other ways to calculate this, but this is one of the easiest)

So now we change to the dealer's perspective, he sold the car for 126.500 and for him that meant a 15% profit. If the purchase value is 100%, then the sale value is 115% (purchase value+15% profit)

Calculate the purchase value:

126.500/115*100 = 110.000

The dealer bought the car for 110.000, sold it for 126.500, so he made a profit of 16.500 (126.500-110.000) which is a 15% profit (15% of 110.000 is 16.500).

Final answer:

A quadratic function with zeros at 2 and 7 can be constructed by multiplying (x - 2) and (x - 7), leading to the function f(x) = (x - 2)(x - 7). A constant 'a' scales the function, which, if not specified, can be assumed to be 1 for simplicity.

Explanation:

The question asks about constructing a quadratic function f with zeros at 2 and 7. In mathematics, a quadratic function is of the form f(x) = ax2 + bx + c, where a, b, and c are constants and a ≠ 0.

To construct a quadratic function with zeros 2 and 7, we utilize the fact that if 2 and 7 are zeros, the function must be divisible by (x - 2) and (x - 7).

Hence, f(x) can be written as f(x) = a(x - 2)(x - 7), where a is a non-zero constant that scales the function.

To determine a, more information about the function is needed, such as a specific value f(x) takes at a certain point.

In the absence of additional information, we can assume a = 1 for simplicity, which gives us the specific quadratic function f(x) = (x - 2)(x - 7).

This function will cross the x-axis at x = 2 and x = 7, making them its zeros.

how do i covert a fraction into a decimal.

Answers

Answer:

By dividing the top number by the bottom.

Step-by-step explanation:

ummmmm

Final answer:

To convert a fraction into a decimal, divide the fraction's numerator by its denominator. Multiplying a decimal by 100 converts it to a percent, and dividing a percent by 100 converts it back into a decimal. This process is used to manipulate numerical values for various mathematical applications.

Explanation:

Converting a Fraction to a Decimal

To convert a fraction into a decimal, you simply divide the numerator (the top number) by the denominator (the bottom number). For example, to convert 3/4 to a decimal, you divide 3 by 4, which equals 0.75. If the fraction is not in simplest form, you may first simplify it before dividing. This is a basic mathematical skill that you will use in many areas of math.

To convert a decimal to a percent, you multiply the decimal by 100. For instance, 0.75 multiplied by 100 equals 75%, because you are essentially finding how many 'parts out of 100' are present in the decimal.

In the case of converting percents, to turn a percent into a decimal, you divide by 100. So, taking 75% and dividing by 100 would give you 0.75, which is the original decimal we started with.

Another example is converting 0.0479 into a decimal that's a number between 1 and 10. To do this, we would move the decimal point to the right two places to get 4.79, as specified by the conversion factor which helps in adjusting units or scaling numbers without changing the value.

Test the claim about the population mean μ at the level of significance α. Claim: μ ≠ 0; α = 0.05; σ = 2.62 Sample statistics: = -0.69, n = 60 Fail to reject H0. There is enough evidence at the 5% level of significance to support the claim. Reject H0. There is enough evidence at the 5% level of significance to reject the claim. Reject H0. There is enough evidence at the 5% level of significance to support the claim.

Answers

Answer:

Correct option:

Fail to reject H₀. There is enough evidence at the 5% level of significance to support the claim.

Step-by-step explanation:

The claim to be tested is:

Claim: μ ≠ 0.

The information provided is:

α = 0.05

σ = 2.62

Sample statistics: = -0.69

n = 60

As the population standard deviation is provided, it can be determined that a z-test for single is used to performed the test.

Decision rule:

If the p-value of the test is less than the significance level, α then the null hypothesis will be rejected and vice-versa.

Compute the p-value as follows:

[tex]p-value=2P(Z<-0.69)\\=2\times [1-P(Z<0.69)]\\=2\times [1-0.7549]\\=0.4902[/tex]

*Use a z-table for the probability.

The p-value = 0.4902 > α = 0.05.

The null hypothesis was failed to rejected at 5% level of significance.Thus, it can be concluded that there is enough evidence at the 5% level of significance to support the claim.
