Answer – C. the sample size 16 is too small

If we toss a coin 16 times in order to test the hypothesis H0: p = 0.5 that the coin is balanced, we can't use the z-test for a proportion in the situations because the sample size 16 is too small. The z-test is best used when the sample size is greater than 30; when the sample size is less than 30, t-test is more appropriate.

Solve the following equation for y.<br>x-5y=-18<br>

olganol [36]

Answer:

y=15x+185

Step-by-step explanation:

Step 1: Add -x to both sides.

x−5y+−x=−18+−x

−5y=−x−18

Step 2: Divide both sides by -5.

−5y−5=−x−18−5

y=15x+185

What is the distance between the points (-6,5) and (8,-2) on a coordinate plane?

Naddik [55]

Distance Formula: $D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Apply the points: $D=\sqrt{(8-(-6))^2+((-2)-5)^2$

Solve: $D=\sqrt{(8-(-6))^2+((-2)-5)^2}\\D=\sqrt{14^2+(-7)^2}\\D=\sqrt{169+49}\\D=\sqrt{218}$

Since the square root of 218 cannot be simplified, the answer is

$D=\sqrt{218}$

Calculate the area of the following figure. All measurements are in centimetres. Give answer to correct two decimal places.

kykrilka [37]

Answer:

Step-by-step explanation:

The shape above is a composite shape having two different shapes like rectangle and semi- circle

Area of rectangle=Length × Breadth

Area of semi circle=1/2πr^2

To find the area of the rectangle naw

Length of the rectangle=6.6

Width of the rectangle=4

A=6.6×4

A=26cm^2

Area of semi-circle=1/2

Diameter of the shape =4cm

Radius=2cm

A=1/2×3.14×2cm x2cm

A=6.28cm^2

Area of the shape=26+6.28cm^2

Area=32.28 to 2 dp
