Answer:

Step-by-step explanation:

From the given information:

The number of children that were randomly allocated to each vaccination group; n₁ = 200,000

No of polio cases X₁ = 57

Now, in the vaccine group:

the proportion of polio cases is:

[tex]\hat p_1 = \dfrac{57}{200000}[/tex]

=  0.000285

The number of children that were randomly allocated to the placebo group, n₂ = 200,000

No of polio cases X₂ = 142

In the placebo group

the proportion of polio cases is:

[tex]\hat p_2 = \dfrac{142}{200000}[/tex]

Null and alternative hypothesis is computed as follows:

H₀: There is no difference in the proportions of polio cases between both groups.  

H₁: There is a difference in the proportions of polio cases between both groups.

Let assume that the level of significance ∝ = 0.05

The test statistic  can be computed as:

[tex]Z = \dfrac{\hat p_1-\hat p_2}{\sqrt{\dfrac{\hat p_1 \hat q_1}{n_1}+ \dfrac{\hat p_2 \hat q_2}{n_2}}}[/tex]

[tex]Z = \dfrac{0.000285-0.000710}{\sqrt{\dfrac{0.000285(1-0.000285)}{200000}+ \dfrac{0.000710(1-0.000710)}{200000}}}[/tex]

[tex]Z = \dfrac{-4.25\times 10^{-4}}{\sqrt{\dfrac{0.000285(0.999715)}{200000}+ \dfrac{0.000710(0.99929)}{200000}}}[/tex]

Z = - 6.03

P-value =  2P(Z < -6.03)

From the Z - tables

P-value =  2 × 0.0000

= 0.000

We reject the H₀ provided that P-value is very less.

Therefore, we may conclude that there is a difference in the proportions of polio cases between the vaccine group and placebo group not due to chance.

Answer:

  x : y : z = 63 : 72 : 80

Step-by-step explanation:

We can make the y-value the same by multiplying the first proportion by 9 and the second by 8.

  x : y = 63 : 72

  y : z = 72 : 80

Now, we can write ...

  x : y : z = 63 : 72 : 80

Answer:

Option (3)

Step-by-step explanation:

Properties of the equal matrices,

1). Every element of the one matrix are equal to the elements of other.

2). Both the matrices have same dimensions.

If,  [tex]\begin{bmatrix}x+3 & y+4\\ 7 & -5\end{bmatrix}=\begin{bmatrix}5 & 0\\ 7 & z\end{bmatrix}[/tex]

[tex]x+3=5[/tex]

[tex]x=2[/tex]

[tex]y+4=0[/tex]

[tex]y=-4[/tex]

Therefore, Option (3) will be the correct option.

Answer:

[tex]r \frac{\text{60 km}}{\text{1000 min}}[/tex]

Step-by-step explanation:

Suppose Kirsten's running rate is  r  meters per second.  This is to be converted to kilometers per minute.

Set up conversion fractions that will get you from

[tex]\frac{\text{m}}{\text{sec}} \rightarrow \frac{\text{km}}{\text{min}}[/tex]

You want to set up fractions so that the  m  on top is replaced with  km  and the  sec  on the bottom is replaced with  min.

[tex]\frac{\text{m}}{\text{sec}} \times \frac{\text{km}}{\text{m}} \times \frac{\text{sec}}{\text{min}}[/tex]

To see how the units work, cancel the m on top of the first fraction and the m on the bottom of the second fraction.  Do the same with the sec on the bottom of the first fraction and the top of the third fraction.  What units are left?  km per min!

To finish this, put the appropriate numbers into each fraction.

[tex]\frac{\text{m}}{\text{sec}} \times \frac{\text{1 km}}{\text{1000 m}} \times \frac{\text{60 sec}}{\text{1 min}} = \frac{\text{60 km}}{\text{1000 min}}[/tex]

This is what you multiply Kirsten's rate by, so she runs

[tex]r \frac{\text{60 km}}{\text{1000 min}}[/tex]

Answer:

9.72

Step-by-step explanation:

s1 = 10.6383 ; s2 = 5.21289

x1 = 147.583 ; x2 = 136.417

n1 = 12 ; n2 = 12

df1 = n1 - 1 = 12 - 1 = 11

df2 = n2 - 1 = 12 - 1 = 11

The test statistic :

(x1 - x2) / sqrt[(sp²/n1 + sp²/n2)]

Pooled variance = Sp² = (df1*s1² + df2*s2²) ÷ (n1 + n2 - 2)

Sp² = ((11*10.6383) + (11*5.21289)) / 22 = 7.926

Test statistic, T* :

(147.583 - 136.417) / √(7.926 * (1/12 + 1/12))

11.166 / √(7.926 * (1/6)

11.166 / √1.321

11.166 / 1.1493476

T* = 9.7150766

Test statistic = 9.72

Answer:

Ryan sprinted 46.33 yards.

Step-by-step explanation:

Ryan sprinted 139 feet.

1 feet = 0.33 Yard

Formula: Divide the length value by 3

Now,

139 ÷ 3 = 46.33

Thus, Ryan sprinted 46.33 yards.

The technology had the biggest impact on the development of the cell theory is microscope. Hence, option C is correct.

The fundamental units of all living organisms are cells. There are many billions of cells in the human body. They give the body structure, absorb nutrients from meals, turn those into energy and perform certain tasks. Additionally, cells have the ability to replicate themselves and contain the body's genetic material.

Each component of a cell has a different purpose. These components include organelles, which are specialized structures that carry out specific functions for the cell.

A cell's nucleus acts as its command center, giving instructions on how to develop, develop, divide, or die. The cell's genetic material, DNA (deoxyribonucleic acid), is also stored there. The envelope, which encircles the nucleus and divides it off from the rest of the cell, shields the DNA and serves as a barrier.

Explanation:

We have three copies of 'a' multiplied, so that's why the exponent for 'a' is 3.

Similarly, the b^2 means we have b*b or two copies of b multiplied together.

Answer:

measure of exterior angle  at  C = 160°

Step-by-step explanation:

An exterior angle of a triangle equals the sum of the two remote interior angles

A and B are the remote interior angles.  So,

m∠A + m∠B = measure of exterior angle  at  C

5x - 10 + 12x = 16x

17x - 10 = 16x

x = 10

measure of exterior angle  at  C = 16x = 16(10) = 160°

Real numbers are just the numbers on the number line. It is the easiest way to think of them. Basically, if you can put the number in question on an infinitely big number line, then it is a real number.

It called identity. Identity equations are conditions that are genuine regardless of what esteem is connected to for the variable. On the off chance that you rearrange a personality condition.

An identity is a balance that remains constant paying little respect to the qualities decided for its variables. They are utilized as a part of streamlining or reworking polynomial math articulations. By definition, the two sides of a character are tradable, so we can supplant one with the other whenever.

Answer:

Step-by-step explanation:

By intersecting secants theorem:

[tex]12(12 - x) = 6(6 + 3) \\ \\ 12(12 - x) = 54 \\ \\ 144 - 12x = 54 \\ \\ 144 - 54 = 12x \\ \\ 90 = 12x \\ \\ x = \frac{90}{12} \\ \\ x = 7.5[/tex]

Answer:

w = 90 feet and l = 490 feet

Step-by-step explanation:

First, determine what you're given:

Perimeter = 1,160 feet

Perimeter = 1,160 feetlength = (w)idth + 400

idth + 400width = w

Next, solve for the length and the width using the perimeter equation (2l + 2w = Perimeter)

2(400+w) + 2w = 1,160 feet

(800 + 2w) + 2w = 1,160 feet

800 + 2w + 2w = 1,160 feet

800 + 4w = 1,160 feet

{ Subtract 800 from both sides }

4w = 360 feet

{ Divide both sides by 4 to isolate w }

w = 90 feet

Finally, you've solved for the width which is 90 feet. Plug this back into your equation for length;

[ l = 400 + w ]

l = 400 + (90)

l = 490 feet

Since it never hurts to check;

2l + 2w = 1,160 feet

2(400+w) + 2w = 1,160 feet

2(400+90) + 2w = 1,160 feet

✅2(490) + 2(90) = 1,160 feet
