Answer:

a. Identify the population of interest in this study.

all the population of the country

b. Identify the sample for the study.

50 adults (the ones that were surveyed)

c. Identify the parameter of interest in the study.

the parameter of interest is the people that believe that coffee shops are overpriced

d. Find and interpret a 95% confidence interval for the parameter of interest.

z score for a 95% confidence level = 1.96

margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579

95% confidence level interval:

0.4 - 0.13579 = 0.26421

0.4 + 0.13579 = 0.53579

95% confidence interval (0.26421 , 0.53579)

earnstyle [38]

Answer:

The intercepts $(x,y) = (\frac{3}{2},-2)$

Step-by-step explanation:

Given:

$4x-1=3y+5$

Required

Determine the intercepts

The equation is a linear equation and the intercepts of the equation is calculated as thus;

For x intercepts; substitute 0 for y

$4x-1=3y+5$

$4x-1=3(0)+5$

$4x-1=0 + 5$

$4x-1=5$

Add 1 to both sides

$4x-1 + 1=5 + 1$

$4x = 6$

Divide both sides by 4

$\frac{4x}{4} = \frac{6}{4}$

$x = \frac{6}{4}$

Simplify fraction to lowest term

$x = \frac{3}{2}$

For y intercept, substitute 0 for x

$4x-1=3y+5$

$4(0)-1=3y+5$

$0 - 1 = 3y + 5$

$-1 = 3y + 5$

Subtract 5 from both sides

$-5 - 1 = 3y + 5 - 5$

$-6 = 3y$

Divide both sides by 3

$\frac{-6}{3} = \frac{3y}{3}$

$-2 = y$

Reorder

$y = -2$

Hence, the intercepts $(x,y) = (\frac{3}{2},-2)$

Andy cut rope for an activity at outdoor camp. He had 504 centimeters of rope to cut into equal-length pieces. How many of the w

mina [271]

Answer: B, C, E

Step-by-step explanation:

For us to know if the options are correct, we just have to multiply the length the rope was cut into by the number of pieces and check if it equals 504 centimeter.

A. 12 pieces of 42.3 centimeter long rope.

= 12 × 42.3

= 507.6

This is wrong

B. 15 pieces of 33.6 centimeter long rope

= 15 × 33.6

= 504cm

This is correct

C. 16 pieces of 31.5 centimeter long rope

= 16 × 31.5

= 504cm

This is correct

D. 20 pieces of 25 centimeter long rope

= 20 × 25

= 500cm

This is incorrect

E. 35 pieces of 14.4 centimeter long rope

= 35 × 14.4

= 504cm

This is correct

Therefore, the correct option are B, C and E.
