Answer:

Option B

Step-by-step explanation:

Average rate of change of a function 'f' in the interval x = a and x = b is given by,

Average rate of change of change = \frac{f(b)-f(a)}{b-a}

Given function is,

g(x) = \frac{5}{x-1}+2

We have to calculate the rate of change in the interval [-4, 3],

Average rate of change = \frac{g(3)-g(-4)}{3-(-4)}

g(3) = \frac{5}{3-1}+1

       = 2.5 + 1

       = 3.5

g(-4) = \frac{5}{-4-1}+1

       = -1 + 1

       = 0

Average rate of change = \frac{3.5-0}{3+4}

                                        = \frac{3.5}{7}

                                        = \frac{1}{2}

Therefore, Option B will be the answer.

  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

Compound Interest Rate Formula: \displaystyle A = P(1 + \frac{r}{n})^{nt}

  • A is final amount
  • P is principle amount
  • r is rate
  • n is compound rate
  • t is time (in years)

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

P = $1900

r = 3% = 0.03

n = 4

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute [CIRF]:                    \displaystyle A = 1900(1 + \frac{0.03}{4})^{4(6)}
  2. (Parenthesis) Divide:              \displaystyle A = 1900(1 + 0.0075)^{4(6)}
  3. (Parenthesis) Add:                  \displaystyle A = 1900(1.0075)^{4(6)}
  4. (Exponents) Multiply:             \displaystyle A = 1900(1.0075)^{24}
  5. Exponents:                             \displaystyle A = 1900(1.19641)
  6. Multiply:                                  \displaystyle A = 2273.19

Determine the measurement of the unknown angle measures in the given figure.
Andrei [34K]

Answer:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

A researcher is interested in estimating the difference in two population proportions. A sample of 400 from each population resu
sergey [27]

Answer: (-0.086, 0.026)

Step-by-step explanation:

The confidence interval for the difference of two population proportion is given by :-

p_1-p_2\pm\ z_{\alpha/2}\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}

Given : Significance level : \alpha: 1-0.90=0.10

Critical value : z_{\alpha/2}=1.645

Sample size : n_1=400,\ n_2=400

p_1=0.61,\ p_2=0.64

The 90% confidence interval for the difference in the population proportions will be :-

0.61-0.64\pm\ (1.645)\sqrt{\dfrac{0.61(1-0.61)}{400}+\dfrac{0.64(1-0.64)}{400}}\\\\\approx-0.03\pm0.056=(-0.03-0.056,-0.03+0.056)\\\\=(-0.086, 0.026)
