A pediatricians office tracks the age (in months) in which 25 babies begin to walk. Use the dot plot at the right to answer the questions below. I Added the picture below please help.

Answer:

Answers A and B respectively

Step-by-step explanation:

In the first pic, they are asking you for the value of the function at the points x = -1 and x = 5. Then you are asked to subtract your results. When the value of 'x' is -1, the 'y' value is 3. When the value of 'x' is 5, the 'y' value is -4. Therefore:

[tex]f(-1)-f(5)=3-(-4)=7[/tex]

Answer A

For the second problem, they are saying that the line connecting points A and B is undefined. This means the slope is undefined along that line. An undefined slope is due to a zero in the denominator. Begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{y_1-1}{x_1+2} =m[/tex]

In order for our slope 'm' to be undefined, set the denominator to zero and see at what 'x' value this occurs at:

[tex]x_1+2=0[/tex]

[tex]x_1=-2[/tex]

Then they say that the line connecting points C and D is zero. A zero slope would mean a zero in the numerator. Again, begin by taking the change in 'y' over the change in 'x' to get:

[tex]\frac{3-y_2}{-5-x_2} =m[/tex]

Set the numerator equal to zero to get:

[tex]3-y_2=0[/tex]

[tex]y_2=3[/tex]

Answer B

Step-by-step explanation:

Formula = A=2(wl+hl+hw)

=> A=2(wl+hl+hw)

=> A = 2((2)(4)+(2.5)(4) + (2.5)(2))

=> A = 2(8 + 10 + 5)

=> A = 2(23)

=> A = 46

[tex] \therefore [/tex] Surface area = 46

Answer:

A=46

Answer:

The skewness of a graph is a function of how much the random variable deviates from the normal distribution.

The shape of the distribution is (c) skewed left

Step-by-step explanation:

From the attached image, we can see that:

The points are concentrated on the left-hand side of the graph, and the points decreases as it approaches the right-hand side.

The above highlight means that:

The shape of the distribution is skewed left

I think the answer Is b i could be wrong it's been a while since I did middle school

Answer:

The answer is 525

Step-by-step explanation:

35 out of 200 people is 7/40 of the people. to find 7/40 of 3,000 you need to divide 3000 by 40 and multiply that with 7. This should give you the answer 525

Solution 1

Total people whose first concert:

(probability of first concert from sample) * total people

Solution 2

a) A random sample because here the interview is with a large group of boys.

b) A fair question as people who don't like football as well can sometimes try out football. So asking them for thier favourite sports is fair.

Answer:

The area of the circle is 75 in^2

Step-by-step explanation:

Since it shows the radius to be 5, we simply do 5^2 to get 25. It also say to use 3 for pi. So, we would do 25*3 to get 75.

Answer:9.029126214

Step-by-step explanation:

Use calculator or do long divisions

Answer:

x = -2, y = -4 (-2,-4)

Step-by-step explanation:

1. Substitute "y = 2x+ in for y in "x + y = -6"

x + 2x = -6

2. Combine like terms:

3x = -6

3. Isolate x:

3x/3 = -6/3

x = -2

4. Substitute the new x-value in one of the equations:

y = 2(-2)

y = -4

The graph should look like the picture attached.

Answer:

It WILL NOT fit inside the box as the length is LONGER THAN the box.

However, diagonally, it can as by The Pythagoras Theorem, a^2+b^2=c^2.

Diagonally, it is 32.984 inches (5s.f)

Answer:

larger circle is 75.4

smaller circle is 50.27

Step-by-step explanation:

Answer:

Larger circle= 75.4

Smaller circle= 50.27

Step-by-step explanation:

Use this formula: C=2πr

Find the radius for bigger and smaller circle

The radis of the smaller is equal to: 12 - 4 =8

radius of smaller circle= 8

radius of bigger circle = 12

make an equation for one of the circles: (i chose the smaller one)

C=2π(8)

C= 16 π

C= 50.27

Now for the bigger circle

C=2π(12)

C=24π

C= 75.39

C= 75.4

Answer:

"What is your favorite vegetable?"  for the first one and Choices A and B are correct for the second one.

Step-by-step explanation:

For the first image/question:

The first survey question is correct and gives you the most data.

"What is your favorite vegetable?"

That question gives a variety of choices and also gives you data similar

to each other.

Ex. 12 people like potatoes, 15 people like corn. 5 people like spinach, etc.

This amount of data is easier to present/graph and also very common/open-ended as opposed to questions like "In which zipcode do you live in?"

Second Question:

The data set can represent the weight of a dozen eggs and could possibly represent the length of leaves from a tree if measured in Centimeters.

A and B are the right choices.

The other few options aren't appropriate due to the data.

Answer:

√85

Step-by-step explanation:

The given shape is a right angled triangle.

Let the missing side length be " x ".

By Pythagoras theorem,

x² = 6² + 7²

x² = 36 + 49

x² = 85

x = √85

Therefore, the missing side length be √85.

Answer:

26.376 because the circumference formula is 2*3.14*radius so the radius of the goal would be 9 because radius is half of diameter which is 18 so 2*3.14*9=56.52 and the basketball's radius would be 4.8 and then 2*3.14*4.8 is 30.144 so the answer is 26.376 hope it helps

Answer: the perimeter of the wood is 67 sq. feet

Step-by-step explanation: i’m taking the same test

Answer:

66.56 cm

Step-by-step explanation:

to find the circumfrence of a full circle you use the equation 2[tex]\pi[/tex]r

as 8 cm is the radius you do  2*3.14*8 which = 50.24

then to find it of quarter of a circle

50.24/4 = 12.56

to find the half line parallel to 17 cm you do 17-8= 9

overall perimeter=

12.56+8+9+10+17+10 = 66.56
