Find the value of the test statistic z using z=^p−p√pq/n.
Anna007 [38]

Answer:

Option C - 4.71

Step-by-step explanation:

We are given the Test statistic for proportion as;

z = (^p − p)/√pq/n

From the question;

^p = 0.15

p = 0.1

q = 1 - 0.1 = 0.9

n = 800

z = (0.15 - 0.1)/√(0.1 × 0.9/800)

z = 0.05/√(0.09/800)

z = 4.71

A scientist builds a Mars rover that can travel 4.9 centimeters per second on flat ground.
tatyana61 [14]

Answer:

75.95cm

Step-by-step explanation:

<u>4.9 multiplied by 15 will represent the 15</u> <u>seconds</u>

4.9 • 15 = 73.5

<u>4.9 divided by 2 will equal the 1/2 seconds</u>

4.9 ÷ 2 = 2.45

<u>add them all together</u>

73.5 + 2.45 = 75.95 cm

PLEASE HELP!!!<br> I’m very confused haha
Neko [114]
The person that factored the polynomial did one thing wrong -- they used minus signs when they should've used plus signs. We can figure this out because of the values of the quantities in the original trinomial. Since all of them are positive, we know that either there are two plus signs or that there is a minus and a plus sign with the value to the right of the plus sign being greater than the value to the right of the minus sign. But, that wouldn't work here, so the only thing wrong with this answer is that the plus signs should be minus signs.

How many garbage cans should be placed in each campground? Explain how you can use addition or multiplication to find the answer
Vikentia [17]

Answer:

Step-by-step explanation:

Multiplication

Ratio of Tables to garbage = 8:3

Small camp ground:

40 picnic tables and let x be the number of garbage cans

\frac{8}{3}=\frac{40}{x}\\\\\frac{8*5}{3*5}=\frac{40}{x}\\\\\frac{40}{15}=\frac{40}{x}\\\\

x = 15

Small campground with 40 picnic table needs 15 garbage cans

Large picnic ground:

120 picnic tables and let y be the number of garbage cans

\frac{8}{3}=\frac{120}{y}\\\\\frac{8*15}{3*15}=\frac{120}{y}\\\\\frac{120}{45}=\frac{120}{y}

y= 45

Big campground with 120 picnic table needs 45 garbage cans
