How do you find b from 24-10b=9

1 answer:

6 0

Well b is equal 1.5 because you need to subtract 24 from 9 and that equal 15. So now you need to divide the 15 from 10 so you get 1.5. Then 10 × 1.5 = 15 so 24 - 15 = 9

Percents

Given that,

Michael is leaving a 15% tip for his waitress.

To find,

What percent of the original price will he pay.

Solution,

Let the original price was 100%.

When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

$115\%=\dfrac{115}{100}\\\\=1.15$

$\dfrac{115}{100}=\dfrac{23}{20}$

So, this is the required solution.

Use the given values of n and p to find the minimum usual value μ−2σ and the maximum usual value μ+2σ. Round to the nearest hund

lbvjy [14]

Answer:

μ−2σ = 1,089.26

μ+2σ = 1,097.62

Step-by-step explanation:

The standard deviation of a sample of size 'n' and proportion 'p' is:

$\sigma=\sqrt{\frac{p*(1-p)}{n} }$

If n=1139 and p =0.96, the standard deviation is:

$\sigma=\sqrt{\frac{p*(1-p)}{n}}\\\sigma = 0.001836$

The minimum and maximum usual values are:

$\mu-2\sigma = (p-2\sigma)*n\\\mu+2\sigma = (p+2\sigma)*n$

$\mu-2\sigma = (0.96-2*0.001836)*1139\\\mu-2\sigma = 1,089.26\\\mu+2\sigma = (0.96+2*0.001836)*1139\\\mu+2\sigma = 1,097.62$
