An exponential function in mathematics is an exponential function is a function of the form where b is a positive real number, and in which the argument x occurs as an exponent. So its a function whose value is a constant raised to the power of the argument, especially the function where the constant is e.

Brianna's gross annual salary is $50,676. What is the recommended maximum monthly rent she should pay?

ANEK [815]

Answer with explanation:

Gross Annual Salary of Brianna's= $ 50,676

Monthly Salary of Brianna's

$=\frac{50676}{12}\\\\=4223$ $

We will use $\frac{28}{36}$ rule here,which states that, 28% of monthly income should be used for housing expenditures,and 36 % of monthly income should be used for paying Debt or Debt Purposes.

So, Maximum Monthly Rent that Brianna can pay

= 28 % of 4223

$=\frac{28}{100} \times 4223\\\\ =\frac{118244}{100}\\\\=1182.44$

=$ 1182 (Approx)

Option C: $ 1182

The ratio of boys to girls at the beach cleanup was 7:8. If there were 42 boys, how many girls were there?

lesantik [10]

It would be 48 girls. 42 divided by 7 equals 6 so then you just times 6 by 8 to figure out how many girls there will be.

source= 8/10 is 80% so you take the remaining 20% which is the percent of increase

1. Find the 90% Cl for the population mean if sample

Elden [556K]

Answer:

The answer is below

Step-by-step explanation:

1)

mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65

Given that the confidence level (c) = 90% = 0.9

α = 1 - c = 0.1

α/2 = 0.05

The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65

The margin of error (E) is given as:

$E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.65*\frac{2.3}{\sqrt{65} } =0.47$

The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)

2)

mean (μ) = 23, SD(σ) = 12, sample size (n) = 45

Given that the confidence level (c) = 88% = 0.88

α = 1 - c = 0.12

α/2 = 0.06

The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56

The margin of error (E) is given as:

$E=Z_{\frac{\alpha}{2} }*\frac{\sigma}{\sqrt{n} } =1.56*\frac{12}{\sqrt{45} } =2.8$

The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)
