Answer:

The number of weeks required = 216 weeks

Step-by-step explanation:

Given that:

Margin of Error E = 200

Confidence interval = 95% = 0.95

Level of SIgnificance = 1 - C.I

= 1 - 0.95

= 0.05

Standard deviation = 1500

The Critical value for Z :

$Z_{\alpha/2} =Z_{0.05/2} \\ \\ = Z_{0.025} = 1.96$

The number of weeks( i.e the sample size (n) ) required is :

$n = (\dfrac{Z_{\alpha/2} \times \sigma}{E})^2$

$n = (\dfrac{1.96 \times 1500}{200})^2$

$n = (14.7)^2$

n = 216.09

n ≅ 216 weeks

In a class of 28 pupils, if 12 are females. Calculate the ratio of males : total

tensa zangetsu [6.8K]

Answer:

16 : 28

Step-by-step explanation:

If 12 out of the 28 pupils are female, we can calculate the number of males by subtracting the number of females from the total number of pupils.

28 - 12 = 16

So, there are 16 males in the class. Now, we know that the ratio of males : total is 16 : 28.

I hope this helps! Have a lovely day!! :)

miss Akunina [59]

Answer and Step-by-step explanation:

Round your final answers to 2 decimal places

μ = 420

σ = 24

a. Highest 20 percent

P (Z > a-420/24) = 0.20

For a highest 20%, according to the table attached, we have to find the z score for 0.30 (0.5 - 0.2)

P(0 < Z < 0.84) = 0.3

a-420/24 = 0.84

a-420 = 20.16

a = 20.16 + 420 = 440.16

weight 440.16

b. Middle 60 percent

P (0 < Z < b-420/24) = 0.3

b = 440.16

P (c-420/24 < Z < 0) = 0.3

c-420/24 = -0.84

c-420 = -20.16

c = 399.84

Weight from 399.84 to 440.16

c. Highest 80 percent

P (d-420/24 < Z < 0) = 0.3

d-420/24 = -0.84

d-420 = -20.16

d = 399.84

d. Lowest 15 percent

P(e-420/24 < Z < 0) = 0.35

e-420/24 = -1.04

e-420 = -29.76

e = 390.24

point a has the coordinates(2,5) point B has the coordinates (6,17) how long is segment ab in simplified radical form

IRISSAK [1]

Answer:

$4\sqrt{10}$

Step-by-step explanation:

We have been given that point A has the coordinates(2,5) point B has the coordinates (6,17).

To find the length of segment AB we will use distance formula.

$\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Upon substituting coordinates of point A and point B in distance formula we will get,

$\text{Distance between point A and point B}=\sqrt{(6-2)^2+(17-5)^2}$

$\text{Distance between point A and point B}=\sqrt{(4)^2+(12)^2}$

$\text{Distance between point A and point B}=\sqrt{16+144}$

$\text{Distance between point A and point B}=\sqrt{160}$

$\text{Distance between point A and point B}=4\sqrt{10}$

Therefore, the length of segment AB is $4\sqrt{10}$ .
