Workout the value of the largest angle

Elanso [62]

Step-by-step explanation:

These angles all add up to 360° because they form a circle, so b + b + 2b + 5b = 360°, and b = 40°. The largest angle is 5b which is 5 * 40 = 200°.

Find the approximate side length of a square game board with an area of 179in ^2.

zysi [14]

<h3><u>Given</u><u>:</u><u>-</u></h3>

Area of a square game board = 179 inches ²

<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u><u>-</u></h3>

Calculate the side of given square game board.

<h3 /><h3><u>Formula</u><u> </u><u>applied</u><u>:</u><u>-</u></h3>

Area of square = ( Side )²

<h3><u>Solution</u><u>:</u><u>-</u></h3>

We know that,

Area of square = ( Side )²

★ Substituting the value in the above formula, we get :

=> 179 = ( Side )²

=> Side = √179

=> Side = 13.37 inches ( approx )

Pachacha [2.7K]

Answer:

a) In the explanation.

b) P=0.09714

c) P=0.0866

d) p=0.208

Step-by-step explanation:

a) The sampling distribution will have this properties:

1 - The sampling distribution of a proportion is equal to the binomial distribution.

2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

$\mu=\pi=0.328$

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

$\sigma_s=\sqrt{\pi(1-\pi)/n}=\sqrt{0.328*(1-0.328)/25}=0.094$

B) The fraction with sample proportion of 0.45 or higher is

$z=(p-\pi)/\sigma=(0.45-0.328)/0.094=1.298\\\\P(p\geq0.45)=P(z\geq 1.298)=0.09714$

C) The fraction with sample proportion of 0.20 or lower is

$z=(p-\pi)/\sigma=(0.2-0.328)/0.094=-1.362\\\\P(p\leq0.2)=P(z\geq -1.362)=0.0866$

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.

Then we have

$z=(p-\pi)/\sigma\\\\p=\pi+z\sigma=0.328+(-1.28)*0.094=0.328-0.120=0.208$
