Answer:

1) Yes, table shows a probability distribution

2) Mean = 1.5

3) Standard Deviation = 1.1

Step-by-step explanation:

PART 1:

For the table to show a probability distribution, the sum of all probabilities should be equal to 1

Sum of probabilities = 0.358 + 0.443 + 0.174 + 0.025

Sum of probabilities = 1

Hence, the table shows the probability distribution.

PART 2:

The formula for mean is given by:

Mean = Sum of terms/ Total no. of terms

Mean = (0+1+2+3) / 4

Mean = 1.5

PART 3:

The formula for standard deviation is given by:

[tex]\sigma=\sqrt{\frac{\sum(x_i-\mu)^2}{N}}[/tex]

Answer:

-7

Step-by-step explanation:

Coefficients are the numbers that multiply the following variables, so in the case of -7yz^2, the coefficient would have to be -7.

Answer:

A: 15%

Step-by-step explanation:

First test:

15 ÷ 20 = 0.75

0.75 * 100 = 75%

Second Test:

18 ÷ 20 = 0.9

0.9 * 100 = 90%

90% - 75% = 15%

Step-by-step explanation:

f(x) = 3x - 2

Let x=4

f(4) = 3*4 - 2

      =12-2

       =10

Answer:

10

Step-by-step explanation:

Replace 4 for all the x values and solve

f(4)=3(4)-2

f(4)=12-2

f(4)=10

Answer:

585.53 new balance

$839.78 - 110.50 - 143.75

Answer: 585.53

Step-by-step explanation:

839.78 - 110.50 = 729.28

729.28 - 143.75 = 585.53

Answer:

Step-by-step explanation:

Amount invested by Nelson = $1,000,000

Interest rate per month = 4.8%

Simple Interest = Principal * Rate * Time/100

simple Interest = $1,000,000 * 4.8 *(1/12)/100

simple Interest = $1,000,000 * 4.8/1200

simple interest = $4,000/ month

Simple interest for one year = $4,000*12 = $48,000

In order to determine the number of years it will take Nelson to earn back his initial investment, we will divide its initial investment by the interest earned on the investment yearly as shown;

amount of years =  $1,000,000/ $48,000

Amount of years = 20.8years ≈ 21years

10.7 years

Answer:

The correct answer is: Calculate income, Total up spending, Categorize expenses, Determine if spending is below income, and Reduce expenses in flexible categories to save or increase savings.

Step-by-step explanation:

28 hours because they are too long from each other

Answer:

Approximately 6.86 hours.

Step-by-step explanation:

Renee sews at a rate of 1.5625 sq ft an hour. Found using square feet divided by hours.

Genera sews at a rate of 2.084 sq ft an hour. Found using square feet divided by hours.

To find how fast they can sew the quilt together, we must add their sewing speeds together: 1.5626 + 2.084 = 3.64583333.

Using this equation we can divide a 25 sq ft quilt by their speed of 3.64583333 to get approximately 6.86 hours.

The answer is approximate because we used rounded decimals.

Answer:

  about 21.9%

Step-by-step explanation:

The effective annual multiplier is ...

  (1 +r/n)^n = (1 +0.20/12)^12 ≈ 1.21939

The rate equivalent is 1 less than this:

  1.21939 -1 = 0.21939 = 21.939%

Answer:

Answer c:  1000

Step-by-step explanation:

Set f(x) = 2 log x - 6 = 0 as a first step in finding the zero or zeros.

2 log x - 6 = 0  becomes log x - 3 = 0 after dividing all three terms by 2.

Then log x = 3, and because "log x" has base 10, the value of x is 10^3, or 1000.

Answer:

n = -1.5

Step-by-step explanation:

[tex]\frac{1}{(\sqrt2)^{3} } } = 0.353553[/tex]

log ( [tex]2^{n}[/tex] ) = log (.353553)

n = [tex]\frac{log (0.353553) }{log (2)} = -1.5[/tex]

Answer:

the answer is C Non durable

Step-by-step explanation:

Answer: the amount of the annuity is $501000

Step-by-step explanation:

We would apply the future value which is expressed as

FV = C × [{(1 + r)^n - 1}/r]

Where

C represents the yearly payments.

FV represents the amount of money

in your account at the end of 25 years.

r represents the annual rate.

n represents number of years or period.

From the information given,

r = 4% = 4/100 = 0.04

C = $12000

n = 75 - 50 = 25

Therefore,

FV = 12000 × [{(1 + 0.04)^25 - 1}/0.04]

FV = 12000 × [{2.67 - 1}/0.04]

FV = 12000 × 41.75

FV = $501000

Answer:

x =  (k-c)/8

Step-by-step explanation:

8x+c= k

Subtract c from each side

8x+c-c= k-c

8x = k-c

Divide each side by 8

8x/8 = (k-c)/8

x =  (k-c)/8
