If 90 percent of a is 44, what is 30 percent of 3a?

Lesechka [4]

90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...

0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded

what is 30% of 3a.....and we know that "a" is 48.89...

0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer

Which of the following estimates at a 95% confidence level most likely comes from a small sample?

dusya [7]

The correct answer is:

A) 60% ± 18%.

Explanation:

In a confidence interval, the margin of error is given by z*(σ/√n), where σ is the standard deviation and n is the sample size.

First we find the value of z:

We want a 95% confidence level; 95% = 95/100 = 0.95.

To find the z-score, we first subtract this from 1:
1-0.95 = 0.05.

Divide by 2:
0.05/2 = 0.025.

Subtract from 1 again:
1-0.025 = 0.975.

Using a z-table, we find this value in the middle of the table. The z-score that is associated with this value is 1.96.

Back to our formula for margin of error, we have 1.96(σ/√n). The larger n, the sample size, is, the larger its square root is. When we divide by a larger number, our answer is smaller; this gives us a smaller margin of error.

This means that if we had a small sample size, we would divide by a smaller number, making our margin of error larger. The largest margin of error we have in this question is 18%, so this is our correct answer.

Brand Number of Packets Cost

mash [69]

Brand 2 is the best value ⇒ B

Step-by-step explanation:

Let us write the Brand, Number of Packets and Cost

→ Brand : Number of Packets : Cost
→ 1 : 12 : $10.68
→ 2 : 16 : $9.44
→ 3 : 18 : $15.30
→ 4 : 24 : $21.84
→ 5 : 30 : $20.40

We need to find what brand is the best value

To find that let us find the price of each packet in each brand, by dividing the price of the brand by the number of the packets, the cheapest price is the best

∵ Brand 1 has 12 packets

∵ The price of Brand 1 is $10.68

∴ The price of each packet = 10.68 ÷ 12 = 0.89

∴ The price of each packet in Brand 1 is $0.89

∵ Brand 2 has 16 packets

∵ The price of Brand 2 is $9.44

∴ The price of each packet = 9.44 ÷ 16 = 0.59

∴ The price of each packet in Brand 2 is $0.59

∵ Brand 3 has 18 packets

∵ The price of Brand 3 is $15.30

∴ The price of each packet = 15.30 ÷ 18 = 0.85

∴ The price of each packet in Brand 3 is $0.85

∵ Brand 4 has 24 packets

∵ The price of Brand 4 is $21.84

∴ The price of each packet = 21.84 ÷ 24 = 0.91

∴ The price of each packet in Brand 4 is $0.91

∵ Brand 5 has 30 packets

∵ The price of Brand 5 is $20.40

∴ The price of each packet = 20.40 ÷ 30 = 0.68

∴ The price of each packet in Brand 5 is $0.68

∵ The least price of a packet is in Brand 2

∴ The cheapest price is Brand 2

Brand 2 is the best value
