The statement is False,

The function and its inverse are reflected about the line y=x. This means that the x and y values are replaced.

So, if a function has a point (2,3) the same point on its inverse will moved be (3,2). This happens for all the points.

Therefore, the statement is false.

3. Kim rolls a 6-sided number cube. What is the probability she rolls a number greater than 3 or a 1? 2/3 1/2 1/12 1/3

Answers

1. If we get an odd number first (probability 5/10 = 1/2), then the only way to get a number greater than 9 is the 10 (probability 1/9, since only 9 papers remain). This gives 1/2 * 1/9 = 1/18.

2. We would expect that P(2 white cards) = P(1 white card)*P(2nd white card given 1 white card).This gives the equation 14/95 = 2/5 * x
Solving for x gives x = 7/19.

f(x) = 1/2x +4
replace f(x) with y
y = 1/2x+4

switch x and y
x = 1/2y +4

solve for y

multiply both sides by 2
2x = y+8

subtract 8 from both sides
2x-8 = y

rewrite with y on the left side: y = 2x-8

replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8

solve for f^-1(4)
replace x with 4 in the equation and solve:

Find the area of the circle in terms of Pi

Answers

Let's start with the area of a circle formula: A = pi * r^2, where r is the radius. The radius is half the diameter. Since the diameter here is 6, the radius is 3. Now we can start solving!
1) A = pi* (3^2)
2) A = 9pi
The area in terms of pi is 9pi cm^2.
I got 9pi cm^2, but it is always helpful to double check work. Hope this helps!

The area of the circle: [tex]A=\pi r^2[/tex]

r - the radius

We have the diameter of the circle: d = 6cm.
d = 2r, therefore

2r = 6cm → r = 3cm

Substitute to the formula:

The scores on a university examination are normally distributed with a mean of 62 and a standard deviation of 11. if the bottom 5% of students will fail the course, what is the lowest mark that a student can have and still be awarded a passing grade? give the answer that is closest to the exact number.

Answers

The lowest score will be obtained as follows:
the z-score is given by:
z=(x-μ)/σ
where:
σ-standard deviation
μ- mean

we are required to evaluate for x, given that P(x<X)=0.05
The value of z that corresponds to 5% will be:
z=-1.65
thus plugging our values we obtain:
-1.65=(x-62)/11
solving for x we get:
-18.15=x-62
thus
x=-18.15+62
x=43.85
x~44
Thus the lowest score is 44

The lowest marks that a student can have and still be awarded a passing grade is 44.

Step-by-step explanation:

Given :

Mean, [tex]\mu = 62[/tex]

Standard Deviation, [tex]\sigma = 11[/tex]

Calculation :

z score is given by,

[tex]z = \dfrac{x-\mu }{\sigma}[/tex] ----- (1)

Value of z corresponds to 5% is,

[tex]z =-1.65[/tex]

from equation (1) we get,

[tex]-1.65=\dfrac{x-62}{11}[/tex]

[tex]x=43.85[/tex]

[tex]\rm x = 44 \;\;(Approx)[/tex]

The lowest marks that a student can have and still be awarded a passing grade is 44.

Find: m∠S, m∠T, m∠Q

Answers

Answer: m∠S = 58 ° ; m∠T = 64 ° ;  m∠Q = 58 ° .
__________________________________________________________

Explanation:
__________________________________________________________

To find "m∠Q" :

Consider the triangle formed by ∠D , ∠1, and ∠Q ;

Given m∠1 = 32° ;

and m∠D = 90° (a "right triangle" ; as shown in "image attached" ;

and by definition, all triangles have 3 angles and 3 sides; and all 3 angles of a triangle add up to 180° ;

→ m∠Q =  180 − (90 + 32) = 180 − 122 = 58 ;
_______________________________________________________

Since this is an "isosceles triangle" ;

→ m∠S = m∠Q = 58° .

Since all angles of any triangle add up to " 180° " ;

→ m∠T = 180 − (58 + 58) = 180 − 116 = 64 ;
____________________________________________

Answer: m∠S = 58 ° ; m∠T = 64 ° ;  m∠Q = 58 ° .

Answer:

s=58 degrees, Q=58 degrees, T=64 degrees

and m∠D = 90° (a "right triangle" ; as shown in "image attached" ;

and by definition, all triangles have 3 angles and 3 sides; and all 3 angles of a triangle add up to 180° ;

T-Shirts R Us advertises shirts as shown below. mc002-1.jpg Which quantities in the advertisement represent a unit rate?

Answers

Answer:

C.) $10 per shirt

Step-by-step explanation:

have a nice day

The option C is more simplified answer for given condition, unit rate is $10.

What is unit rate?

When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another. When the rate's denominator is 1, we refer to the rate as a unit rate.

Given

There are 5 shirts in the image given to us composed of 3 white shirts and 2 black shirts.

A rate with 1 as its denominator is known as a unit rate.

Option A: A ratio of 3:2 or a fraction of 3/2 is indicated by 3 white shirts and 2 white black shirts.

The denominator is not 1, hence this cannot be a unit rate.

Option B: 5 white shirts to 2 black shirts. This cannot be a unit rate because the fraction 2/5 will not have 1 as the denominator.

Choice C: $10 for each shirt. Because it represents a ratio of 10:1 or a fraction of 10/1, this rate is a unit rate. Therefore, the price of 5 shirts will be $50.

D: $50 for each shirt. Because option C has provided us with a more straightforward sum of $10, which we must accept as we are dealing with unit rates, this would not be a unit rate in this question.

Hence Option C is most suitable answer.

What is right triangle?

Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.

What is Pythagoras theorem?

A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

perpendicular² + base² = hypotenuse²

Given,

Side length of each triangle = 4 feet

Hypotenuse of each triangle = 9 feet

Shared side = x

Given the triangles are right angled,

According to Pythagoras theorem,

a² + b² = c²

Here, a = 4 , b = x , c= 9

Substitute the values in Pythagoras theorem,

4² + x² = 9²

16 + x² = 81

x² = 81 - 16

x² = 65

Taking square root on both sides

x = √65

x = 8.062

x = 8.1 (Rounding nearest tenth)

Hence, the center height of tent is 8.1 feet.

The required 1/8 divided by 6 is equal to 1/48.

To solve 1/8 divided by 6, we can rewrite it as a fraction. The reciprocal of 6 is 1/6, so the division problem becomes (1/8) * (1/6). To multiply fractions, we multiply the numerators together and the denominators together.

Step 1 is given as:
= (1/8) * (1/6)

Step 2(simplification) is given as:

Mason earns $70,000 per year and puts 7% of his earnings into a savings account. What is the total amount in Mason's account after 1 year if the interest rate is 3%?
A. $147
B. $72,100
C. $5,047
D. $2,100

Answers

The answer is B. $5,047.

Annual income of Mason is 70,000 dollars.

He saves 7% of his annual earnings into a saving account.

So, his savings would be 7% of 70,000 = 0.07 x 70,000 = 4,900 dollars.

The saving account gives an interest rate of 3% per annum.

So the interest accrued on 4900 dollars over the year would be 3% of 4,900 = 0.03 x 4,900 = 147 dollars.

Total amount in the saving account would be sum of principal amount and interest accrued.

Total balance = principal amount + interest accrued.

Total balance = 4900 + 147 = 5,047 dollars.

Hence, option C is correct i.e. 5,047 dollars.

Sunny's garden has 9 tomato plants, 5 pepper plants, 3 squash plants, and 6 pumpkin plants. For every 3 tomato plants in Sunny's garden, there is 1 ____ plant.

from the list of plants there are 3 squash plants

3 squash plants x 3 tomato plants = 9 total tomato plants

the answer is Squash Plants

Answer: Squash plant is the right answer to fill the blank.

Step-by-step explanation:

Since we have given that

Number of tomato plants = 9

Number of pepper plants = 5

Number of squash plants = 3

Number of pumpkin plants = 6

Since the ratio of tomato plants to squash plants is 9 : 3 = 3 : 1.

So, for every 3 tomato plants in Sunny's garden, there is 1 squash plant.

Hence, Squash plant is the right answer to fill the blank.

Given a mean of 24.5 and a standard deviation of 1.7, within how many standard deviations of the mean do the values 24, 23, 28, 23, 24, and 25 fall?

Answers

It would be 3. I hope this helps!

Given mean = 24.5 and standard deviation = 1.7

Within 1 standard deviations, x ∈ [24.5 - 1.7 , 24.5 + 1.7] or [22.8 , 26.2].

Within 2 standard deviations, x ∈ [24.5 - 2(1.7) , 24.5 + 2(1.7)] or [21.1 , 27.9].

Within 3 standard deviations, x ∈ [24.5 - 3(1.7) , 24.5 + 3(1.7)] or [19.4 , 29.6].

Given values are 24, 23, 28, 23, 24, and 25.

So {24, 23, 23, 24, 25} fall within 1 standard deviation and {28} falls within 3 standard deviations.
