A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample

Irina-Kira [14]

Answer:

Step-by-step explanation:

From the information given,

Number of sample, n = 200

Probability of success, p = 43/100 = 0.43

q = 1 - p = 1 - 0.43

q = 0.57

For a confidence level of 95%, the corresponding z value is 1.96.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.96 ×√(0.43 × 0.57)/200

= 1.96 × 0.035 = 0.0686

The upper boundary of the population proportion is

0.43 + 0.0686 = 0.5

The lower boundary of the population proportion is

0.43 - 0.0686 = 0.4

The error in the solution is

phat = 0.43/200 = 0.00215

Also,

[-0.0043, 0.0086] is wrong

Find the greatest common factor. 2r, 4r

ipn [44]

Answer:

GCF: 2r

Step-by-step explanation:

The Greatest Common Factor(GCF) is the biggest factor you can divide both numbers by. For these numbers we cannot divide by a bigger number than 2r, and that happens to be the greatest common factor because 4r can be divided by 2r.

Hopes this helps!

Pls help with number 5

vova2212 [387]

I believe it is asking for the same number basically written 3 different ways, so it could be 1 1/2, 6/4 and 1.5 because those are all the same number
