The missing graphics is in the attachment.

Answer: Graphic of alternative D.

Step-by-step explanation: Inverse function is a fucntion that inverses another function: Generally, x is the variable and y is the function. In inverse function, y is the variable and x is the function. For example, f(x) = y if and only if g(y) = x.

The graphic of an inverse function is the "reflexion" of the original function over the identity line y=x.

In each alternative from the image, the graphs represented a function and its inverse, however, in alternative D the dashed line indicates the identity line y = x correctly and its relationship with the function and its inverse. Therefore, <u>Graph D</u> is the correct alternative.

On Friday there were 8 snowboarders for every 3 skiers at Slovak ski resort. On Saturday the ratio of the number of snowboarders

atroni [7]

Answer:

There are 46 more skiers than snowboarder

Step-by-step explanation:

Given

Ratio of Snowboarders to Skiers

On Friday:

$Ratio = 8 : 3$

On Saturday:

$Ratio = 4 : 7$

Population = 168

Required

Determine the difference in the number of skiers and snowboarders on Saturday

On Saturday, we have

$Ratio = 4 : 7$

Calculate Total

$Total = 4 + 7$

$Total = 11$

Calculate the number of skiers

$Skiers = \frac{7}{11} * 168$

$Skiers = \frac{1176}{11}$

$Skiers = 107$ (Approximated)

Calculate the number of snowboarders

$Snowboarders = \frac{4}{11} * 168$

$Snowboarders = \frac{672}{11}$

$Snowboarders = 61$ (Approximated)

Calculate the difference

$Difference = 107 - 61$

$Difference = 46$

<em>Hence, there are 46 more skiers than snowboarder</em>

A four-person committee is chosen from a group of eight boys and six girls. If students are chosen at random, what is the probab

Lapatulllka [165]

Answer: 0.07

Step-by-step explanation:

in the group, we can have only 4 persons.

we have 8 boys, and 6 girls.

We want to find the probability that in the comite we have only boys.

Ok, for the first selection, the probability of selecting a boy is equal to the number of boys divided the total number of the group ( 8 + 6 = 14) this is

p1 = 8/14.

For the second selection we do the same, but we already slected a boy, so now the number of boys is 7, and the total number of posibilities is 13.

p2 = 7/13.

for the third selection we do the same, in this case the probability is

p3 = 6/12

for the fourth selection the probability will be:

p4 = 5/11

The joint probability, of all the events happening at the same time, is equal to the product of the singular probabilities:

P = p1*p2*p3*p4 = (8/14)*(7/13)*(6/12)*(5/11) = 0.07

Using a ruler and a compass,Jimmy constructs a square inscribed within a circle. He starts by drawing a circle with a center at

lana66690 [7]

Answer:

He set the compass on a, with the width slightly wider than the distance to o and drew an arc above and below o. He then set the compass on b, without changing the width on the compass and did the same thing. True

He drew a line through where the arc pairs intersected and then labeled the points where this line crossed the top and bottom of the original circle. True

He set the compass on o, with the width slightly wider than the distance to b, and he drew a slightly larger circle around the original circle. False

He used the points that were marked along the circumference of the original circle as the vertices for the square. True
