Management at a seaside resort is publishing a brochure and wants to include a statement about the proportion of clear days duri
Ymorist [56]

Answer: B. 264

Step-by-step explanation:

Formula to calculate the sample size 'n' , if the prior estimate of the population proportion (p) is available:

n= p(1-p)(\dfrac{z}{E})^2

, where z = Critical z-value corresponds to the given confidence interval

E=  margin of error

Let p be the population proportion of clear days.

As per given , we have

Prior sample size : n= 150

Number of clear days in that sample = 117

Prior estimate of the population proportion of clear days = p=\dfrac{117}{150}

E= 0.05

The critical z-value corresponding to 95% confidence interval = z*= 1.95 (By z-table)

Then, the required sample size will be :

n= \dfrac{117}{150}(1-\dfrac{117}{150})(\dfrac{1.96}{0.05})^2

Simplify ,

n= (0.1716)(39.2)^2

n= 263.687424\approx264

Hence, the sample size necessary to construct this interval =264

Thus the correct option is B. 264

Point D is 1/2 of the distance between which two points?
USPshnik [31]

Answer:

B and E

Step-by-step explanation:

B = - 6, D = - 2, E = 2

d(B, D) = - 2-(-6)= - 2 + 6 = 4 units

d(D, E) 2 - (-2) = 2 + 2 = 4

Since, d( B, D) = d( D, E)

Therefore, Point D is 1/2 of the distance between B and E.

Pls someone help me find the answers
Alecsey [184]

Answer:

x = 145°

Step-by-step explanation:

We know that y = 98°, so we can find ∠DBC:

180°-y = ∠DBC

180°-98° = 82°

We also know that z = 63°, therefore we can apply <u>exterior angle of triangles</u> to find x.

∠DBC + z = x

82°+63° = x

x = 145°
