Will ran four miles on his first day of training. The next day he ran one-third that distance. How far did he ran the second day?

Answers

Answer 1

4/1 times 1/3 is 4/3 or 1 1/3 miles on the second day of training.

Answer 2

To solve, we multiply the distance he ran on the first day by 1/3. This lets us find out how far he ran the second day.

4mi*1/3=1 1/3mi

Will ran 1 1/3 miles on the second day.

Sabah has $450 to pay for college textbooks. She expects to pay about $75 per book. Her friend told her that 4 of them can be checked out of the library for free.

Complete the equation below to find the total number of books that Sabah can get for her classes. Use b to represent the total books.

Answers

450 is the total amount of money and it is divided by 75 to get the total number of books possible under that amount per book. The reason four is added is that it is stated that four of the books necessary are to be taken from a library for free. Therefore, when solved, b is equal to 10

Find the length of the chord of a circle of radius 100 feet subtended by an angle of 75◦ ?

Answers

1. By definition, the chord of a circle is a segment that joins the two points of an arch and if it passes through the center of the circle, is called "diameter". There is a formula that you can use to find the chord lenght. This is:

Chord lenght=2rSin(A/2)

2. Let's convert the angle from degrees to radians:

75°π/180°=5π/12

3. So, you have:

r: It is the radius of the circle (r=100 feet).
Sin: It is the sine function.
A: It is the angle subtended at the center by the chord (A=5π/12).

4. When you substitute these values into the formula (Chord lenght=2rSin(A/2)), you obtain the chord lenght:

Chord lenght=2rSin(A/2)
Chord lenght=2(200 feet)(Sin(5π/12/2))

5. Therefore lenght of the chord is:
Chord lenght=18.2706 feet

Ans. the probability is 0.07393 to 5 places of decimal.

Answer:

0.1172

Step-by-step explanation:

The formula for the probability in a binomial distribution (n trials, r successes) is

[tex]\binom{n}{r}(p)^r(1-p)^{n-r}[/tex] where p is the probability of success.

For flipping a coin, the probability of success, p, is 0.5.

The number of trials, n, is 10. The number of successes, r, is 7. This gives us

[tex]\binom{10}{7}(0.5)^7(1-0.5)^{10-7}\\\\\binom{10}{7}(0.5)^7(0.5)^3=0.1171875 \approx 0.1172[/tex]

Please help me figure how to explain ??

Answers

First of all, let's explain what SSA means. This is a concept of triangles and means Side, Side, Angle. This happens when we know two sides and an angle that is not the angle between the sides as shown in the Figure below.

On the other hand, the law of sines states that for the triangle below it is true that:

[tex]\frac{a}{sinA}= \frac{b}{sinB}= \frac{c}{sinC}[/tex]

According to the problem we will explain three cases that result in zero, one or two triangles while applying SSA. Let's solve this problem with examples.

First. Case zero solution (No solution)

Suppose that:

[tex]b=8 \\ c=9 \\ B=75^{\circ}[/tex]

So let's start by finding angle C. According to the law of sines:

[tex]\frac{c}{sinC}= \frac{b}{sinB} \\ \\ \therefore \frac{9}{sinC}= \frac{8}{sin75^{\circ}} \\ \\ \therefore sinC= \frac{9sin75^{\circ}}{8} \\ \\ \therefore C=sin^{-1}(1.086)[/tex]

If you try to take the arcsin of a number that's larger than one it is not going to work. Therefore there is no solution in this case.

Second. Case one solution

Suppose that:

[tex]b=10 \\ c=9 \\ B=42^{\circ}[/tex]

Then according to the law of sines:

[tex]\frac{b}{sinB}= \frac{c}{sinC} \\ \\ \therefore \frac{10}{sin42^{\circ}}= \frac{9}{sinC} \\ \\ \therefore sinC= \frac{9sin42^{\circ}}{10}=0.602 \\ \\ \therefore C=sin^{-1}(0.602)=37.01^{\circ} \ or \ C=180^{\circ}-37.01^{\circ}=142.99^{\circ}[/tex]

But we know that:

[tex]A+B+C=180^{\circ} \\ \\ If \ C=37.01^{\circ} \ then: \\ A=180^{\circ}-42^{\circ}-37.01^{\circ}=79.01^{\circ} \\ It's \ a \ solution \\ \\ If \ C=142.99^{\circ} \ then: \\ A=180^{\circ}-42^{\circ}-142.99^{\circ}=-4.99^{\circ} \\ It's \ not \ a \ solution[/tex]

Therefore we have one solution

Third. Two solutions.

Suppose that:

[tex]B=30^{\circ} \\ b=7 \\ c=8[/tex]

So:

[tex]\frac{b}{sinB}= \frac{c}{sinC} \\ \\ \therefore \frac{7}{sin30^{\circ}}=\frac{8}{sinC} \\ \\ \therefore sinC=\frac{8sin30^{\circ}}{7}=\frac{4}{7} \\ \\ \therefore C=sin^{-1}(\frac{4}{7})=34.85^{\circ} \ or \ C=180^{\circ}-34.85^{\circ}=145.15^{\circ} \\ \\ Thus: \\ \\ If \ C=34.85^{\circ} \ then:\\ A=180^{\circ}-30^{\circ}-34.85^{\circ}=115.15^{\circ} \\ It's \ a \ solution \\ \\ If \ C=145.15^{\circ} \ then:\\ A=180^{\circ}-30^{\circ}-145.15^{\circ}=4.85^{\circ} \\ It's \ a \ solution[/tex]

Therefore there are two solutions.

Conclusion: For triangles to make sense the shortest side must be across the lowest angle and the longest side must be across the largest angle.

Find the value of z such that 0.96420.9642 of the area lies between −z−z and z. round your answer to two decimal places.

Answers

If z represents the variable of the standard normal distribution curve N(0,1), which is symmetrical about z=0, then we look for
P(z)-P(-z)=0.9642=1-2P(-z) => P(-z)=(1-0.9642)/2=0.0179
=>
-z=-2.099192
=> z=2.099192
Check:
P(2.099192)-P(-2.099192)=0.9642 ok

Final answer:

The value of z where 0.9642 of the area lies between -z and z is found by looking up the area 0.4821 (half of 0.9642) in a Z-table or using the invNorm function with 0.4821 on a normal distribution calculator. This will provide the z-score to be rounded to two decimal places.

Explanation:

You are looking for the value of z such that 0.9642 of the area under the normal distribution curve lies between −z and z. To find this, you'll need to use the properties of the standard normal distribution, commonly represented by a Z-table.

For a symmetrical distribution, half of the area you are interested in would be to the left of 0 and half to the right. Since 0.9642 is the total area between −z and z, we need to find the z-score that corresponds to half of this area from the mean to one end. Specifically, you're looking for the z-score where the area to the left is 0.4821 (0.9642 divided by 2).

Using a Z-table or an inverse normal function on a calculator, you can find the z-score that corresponds to an area of 0.4821. If you're using a Z-table, look up the closest area in the body of the table and find the corresponding Z-score. If you're calculating it (such as with the invNorm function on a calculator like the TI-83 or 84), input the left-tail area. The answer should be rounded to two decimal places.

The calculation would be something similar to invNorm(0.4821, 0, 1), where 0 and 1 are the mean and standard deviation of the standard normal distribution, respectively.

If z represents the variable of the standard normal distribution curve N(0,1), which is symmetrical about z=0, then we look for

P(z)-P(-z)=0.9642=1-2P(-z) => P(-z)=(1-0.9642)/2=0.0179

-z=-2.099192

=> z=2.099192

Check:

P(2.099192)-P(-2.099192)=0.9642

The Symmetric Property of Congruence allows you to say that if ∠LMN ≅ ∠NSP, then ∠NSP ≅ ∠LMN.

Hope this helps..!!

Thank you :)

The correct completion of the statement using the Symmetric Property of Congruence is: If [tex]$ \angle LMN \cong \angle NSP $[/tex], then [tex]$ \angle NSP \cong \angle LMN $[/tex].

The Symmetric Property of Congruence states that if two angles are congruent, then the second angle is also congruent to the first. In other words, the order in which the angles are listed does not affect the congruence. Therefore, if [tex]$ \angle LMN $[/tex] is congruent to [tex]$ \angle NSP $[/tex], it follows that[tex]$ \angle NSP $[/tex] is congruent to [tex]$ \angle LMN $[/tex]. This property is a fundamental aspect of geometry that allows us to reverse the order of the angles in a congruence statement without changing the meaning of the statement.

Write a function numberofpennies() that returns the total number of pennies given a number of dollars and (optionally) a number of pennies. ex: 5 dollars and 6 pennies returns 506.

Answers

What language are you writing this in? C? Javascript? Java? Are you allow to have parameters?
The general idea should be the same. Since 1 dollar = 100 pennies, we should write something like...

Java:
public static double numberofpennies(double dollars, double penny) {
double sum = 0;

// The amount of pennies that dollar represents
double converted = dollars * 100.0;

sum = converted + penny;

return sum;
}
Note: You should probably place this question under the category computer and technology instead of math. Also, this is just an example of what you could possibly write. What parameters you are allowed to use, what type (double? int? etc?) of pennies are you allowed to return, etc. depends on how you write it.

Final answer:

The numberofpennies() function calculates the total number of pennies by converting dollars to pennies and adding any additional pennies. It multiplies the number of dollars by 100 and adds the extra pennies to find the total.

Explanation:

Function to Calculate Total Number of Pennies

The function numberofpennies() is used to calculate the total number of pennies for a given amount of dollars and optionally, additional pennies. To do this, it converts the dollars into pennies and then adds the additional pennies if they are provided.

Example Function in Python

Here is an example of how one might write the numberofpennies() function in Python:

def numberofpennies(dollars, extra_pennies=0):
return (dollars * 100) + extra_pennies

# Example usage:
total_pennies = numberofpennies(5, 6)
print(total_pennies) # This would print 506

In this example, the function takes two arguments: dollars, which is a mandatory argument representing the number of dollars, and extra_pennies, which is an optional argument representing additional pennies. The function then returns the total number of pennies by multiplying the number of dollars by 100 and then adding the extra pennies if any.

The tax revenue that a small city receives increases by 3.5% per year. in 1990, the city received $250,000 in tax revenue. Determine the tax revenue in 1995 and in 2006.

Answers

Hello there! For this question, because the revenue increases, we will be compounding. The formula for coompounding is P(1 + r)^t, where P = initial amount, r = rate in decimal form, and t = time in years. First, let's add 1 into the rate. 3.5% is 0.035 in decimal form. 1 + 0.035 is 1.035. 1995 is 5 years from 1990 and 2006 is 16 years from 1990. Let's start by raising it to the 5th power. 1.035^5 is 1.187686306. Do not delete the number from your calculator. Multiply it by 250,000. When you do, you get 296,921.5764 or 296,921.58 when rounded to the nearest hundredth. We solved for 1995. Now, let's solve for 2006. 1.035^16 is 1.73398604. Again, do not delete the number from your calculator. Multiply by 250,000. When you do, you get 433,496.509957 or 433,496.51 when rounded to the nearest hundredth. There. Here are your answers:

1995: $296,921.58
2006: $433,496.51

Final answer:

To find the tax revenue in 1995 and 2006 for a city with an annual increase of 3.5%, we use the formula for exponential growth. The revenue in 1995 is calculated to be $296,923, and for 2006, it is calculated to be $438,995.

Explanation:

The tax revenue that a small city receives increases by 3.5% per year. To calculate the tax revenue for the years 1995 and 2006, we can use the formula for exponential growth: Final Amount = Initial Amount * (1 + Growth Rate)Number of Years.

For 1995, which is 5 years after 1990, the calculation would be:
Revenue in 1995 = $250,000 * (1 + 0.035)5
Revenue in 1995 = $250,000 * (1.035)5
Revenue in 1995 = $250,000 * 1.18769
Revenue in 1995 = $296,923

Similarly, for 2006, which is 16 years after 1990, the calculation would be:
Revenue in 2006 = $250,000 * (1 + 0.035)16
Revenue in 2006 = $250,000 * (1.035)16
Revenue in 2006 = $250,000 * 1.75598
Revenue in 2006 = $438,995

Answers

Answer:

C. 11 is the correct answer

Step-by-step explanation:

The table representing the probabilities of player's batting average is,

Left-Handed pitchers Right-Handed pitchers

Bats Left 0.285 0.175

Bats Right 0.215 0.250

So, when the players bats left 100 times,

The probability of hits he gets when faced by left-handed pitchers = 0.285 × 100 = 28.5

The probability of hits he gets when faced by right-handed pitchers = 0.175 × 100 = 17.5

Thus, the difference in the hits = 28.5 - 17.5 = 11

Hence, the player will get 11 more hits t when he faces left-handed pitchers as opposed to right-handed pitchers.

[tex]slope= \frac{ y_{1} - y_{2} }{ x_{1} - x_{2} } [/tex]

Plug in the data we know.

[tex]slope= \frac{ y_{1} - y_{2} }{ x_{1} - x_{2} } = \frac{2-8}{3-7} = \frac{-6}{-4}= \frac{6}{4} = 1.5 [/tex]

Answer:

3/2

Step-by-step explanation:

To find the slope of the line that contains the points A(3, 2) and B(7, 8), we can use the formula for slope:

slope = (change in y) / (change in x)

Let's calculate the values:

Change in y = 8 - 2 = 6

Change in x = 7 - 3 = 4

Now, we can find the slope:

slope = 6 / 4 = 3/2

Therefore, the slope of the line that contains the points A(3, 2) and B(7, 8) is 3/2.

PLEASE SHOW ALL WORK!!!
The base of a triangle measures (8x + 2) units and the height measures (4x − 5) units.

Answers

Part A: We know that the equation for finding the area of a triangle is [tex]A=.0.5(base)(height)=0.5bh[/tex]; we also know that [tex]base=(8x+2)[/tex] and [tex]height=(4x-5)[/tex], so the only thing we need to do is replacing those values into our Area equation and solve for x:
[tex]A=0.5(8x+2)(4x-5)[/tex]
[tex]A=0.5(32 x^{2} -40x+8x-10)[/tex]
[tex]A=0.5(32 x^{2} -32x-10)[/tex]
[tex]A=16 x^{2} -16x-5[/tex]
Now the only thing left is factor the quadratic polynomial:
[tex]A=(4x+1)(4x-5)[/tex]

W can conclude that the area of our triangle is [tex]A=(4x+1)(4x-5)[/tex]

Part B: Our polynomial has three terms, so is a trinomial; also, our polynoal only has one variable, [tex]x[/tex], and the largest exponent of that variable is 2; therefore is a degree 2 polynomial. In summary, we have a trinomial of degree 2.

Part C: Part A demonstrate the closure property of polynomials because after multiplying tow polynomials we obtained another polynomial.

Part A:

As given,

Base of the triangle = 8x + 2 units

Height of the triangle = 4x − 5 units

Formula to find area of a triangle = [tex]\frac{base * height}{2}[/tex]

= 0.5bh

we have been given base and height, so the area becomes,

area = [tex]\frac{(8x+2)(4x-5)}{2}[/tex]

area = 0.5(8x+2)(4x-5)

= 0.5(32x²-32x-10)

= 16x²-16-5

after factoring it, we get

area = (4x-5)(4x+1) units.

Part B:

It is a degree 2 polynomial as the polynomial has one variable that is x, and the largest exponent of that variable is 2.

Part C:

Part A demonstrates the closure property of polynomials because after multiplying two polynomials we get another polynomial.
