Answer:

66 inches ;

95.44 ;

4

Step-by-step explanation:

Given that:

Normal distribution with;

Mean(m) = 66 inches

Standard deviation (s) = 3 inches

A.) If a horse is chosen at random, Expected height will be equal to the mean of the distribution = 66 inches

B.) percentage horses who are between 60 and 72 inches

Zscore = ( x - m) / s

x = 60

Zscore = (60 - 66) / 3

Zscore = - 6/3

= - 2

P(Z < - 2) = 0.0228

Zscore = ( x - m) / s

x = 72

Zscore = (72 - 66) / 3

Zscore = 6/3

= 2

P(Z < 2). = 0.9772

Between 60 and 72

0.9772 - 0.0228 = 95.44

c) In a particular year there are 25 horses running in the Melbourne Derby. How many of these would you expect to have a height of less than 63 inches?

Zscore = ( x - m) / s

x = 63

Zscore = (63 - 66) / 3

Zscore = - 3/3

= - 1

P(Z < - 1) = 0.1587

0.1587 * 25 = 3. 967 = 4

Answer:

a. observational study

Step-by-step explanation:

An observational study is one in which the researcher seeks to discover the effect of a disease or treatment without interference on those who are affected or not affected by it. Observational studies could be of two types namely; the case-control, and the cohort study. The research given above is a cohort study because it compares a group of people born in the same time period and checks for the presence of a disease that could be linked to the vaccinations administered at birth.

A case-control study compares those affected by the disease to those not affected by it. An experimental study assigns the participants to groups and there is a control or placebo group. After this, the results from the groups are compared.  

Answer:

there will be 9

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

We have to solve for [tex]x[/tex] so we isolate the value of x in the expression.

[tex]2x + 2x - 9 = 19[/tex]

[tex]2x + 2x - 9 + 9 = 19 + 9[/tex]

[tex]2x + 2x = 28[/tex]

[tex]4x = 28[/tex]

[tex]\frac{4x}{4} = \frac{28}{4}\\[/tex]

[tex]x = 7[/tex]

Answer:

20.3 < 35 - 9.8t < 30.1

Step-by-step explanation:

Given the Velocity model:

V = 35 – 9.8t ; t = time in seconds

V when t is between 0.5 and 1.5

V when t = 0.5

V = 35 - 9.8(0.5)

V = 35 - 4.9 = 30.1

Vt=0.5 = 30.1

V when t = 1.5 ;

V = 35 - 9.8(1.5)

V = 35 - 14.7 = 20.3

Vt= 1.5 = 20.3

Hence V, between, t = 0.5 and t = 1.5

Vt=1.5 < V < Vt=1.5

20.3 < V < 30.1

V = 35 - 9.8t

20.3 < 35 - 9.8t < 30.1

Answer:

9/1 x 3/1

Step-by-step explanation:

Given:

In ΔGHI, GI is extended through point I to point J.

[tex]m\angle GHI=(3x+13)^\circ,m\angle IGH=(x+8)^\circ,m\angle HIJ=(6x-5)^\circ[/tex]

To find:

The measure of angle GHI.

Step-by-step explanation:

According to exterior angle theorem, the measure of an exterior angle of a triangle is equal to the sum of measure of two opposite angles.

Using exterior angle theorem, we get

[tex]m\angle HIJ= m\angle GHI+m\angle IGH[/tex]

[tex](6x-5)^\circ=(3x+13)^\circ+(x+8)^\circ[/tex]

[tex](6x-5)^\circ=(4x+21)^\circ[/tex]

[tex]6x-4x=21+5[/tex]

[tex]2x=26[/tex]

Divide both sides by 2.

[tex]x=13[/tex]

Now,

[tex]m\angle GHI=(3x+13)^\circ[/tex]

[tex]m\angle GHI=(3(13)+13)^\circ[/tex]

[tex]m\angle GHI=(39+13)^\circ[/tex]

[tex]m\angle GHI=52^\circ[/tex]

Therefore, the measure of angle GHI is 52 degrees.

Answer:

-2x^2-20x-46

Step-by-step explanation:

-2(x^2)-20x-46

-2(x^2) -2(10x)-46

Answer: 19 XD

Step-by-step explanation: u add

M = (  (x1 + x2) / 2  ,  (y1 + y2) / 2 )

(9, 0) = (  (x1 + 12) / 2  ,   (y1 + 3) / 2)

Break up this formula into two equations.

(x1 + 12) / 2 = 9           and          (y1 + 3) / 2 = 0

Solve for x1 and y1 from the equations.

another way to explain it

the formula for finding the midpoint of a segment given the coordinates of its endpoints is:

((x1+ x2)/2, (y1 +  y2)/2   {Average of the x coordinates, average of the y coordinates}.

For this problem we know the coordinates of the midpoint along with one of the endpoints.

So the x coordinate of the midpoint (9) must equal (12 + x2)/2.

That is:  9 = (12 + x2)/2  Solve for x2. Follow a similar pattern to find the y coordinate of the unknown endpoint.

and another way

The x's are 3 apart and the y's are 3 apart. The other endpoint is (9 - 3, 0 - 3), or (6,-3).

hope this helped you have a good day this was ez

Step-by-step explanation:

Answer:

the answer is 1/2 because of the multiple of 3

Answer:

30 students

Step-by-step explanation:

you have a ratio, and an unknown amount, so set up a proportion

[tex]\frac{2}{3} = \frac{x}{18}[/tex] I used x because the amount of boys is unknown

so then, cross multiply

(so do 3 times x, and 2 times 18)

[tex]3x=36[/tex]

then divide both sides by 3 to get x by itself, and you get

[tex]x=12[/tex]

this means there are 12 boys in the class. because the problem is asking for the total number of students, add 12 and 18 (the number of boys and girls).

you get 30, so there are 30 students in her class.

Answer:

4/35 pounds

Step-by-step explanation:

4/7 ÷ 5 is the same as

[tex]\frac{4}{7} * \frac{1}{5}[/tex]

4x1/7x5

= 4/35

Answer:

4/35

Why?

To figure this out I had to make 5 into a fraction. 5/1. Now, I had to find a common denominator. 35. From there I changed both fractions, divided them, and got my answer.

Answer:

g(f(-1)) = 20

Step-by-step explanation:

first we need to compute f(-1)

f(-1) = -( -1 ) + 4 = 1 + 4 = 5

then we take g(5):

g(5) = ( 5 )^2 - 5 = 25 - 5 = 20
