Answer:

492

Step-by-step explanation:

6x82

Answer:

the answer is 492 the person above me is correct!!

Step-by-step explanation:

Answer:

A:

2(x + 2) + 2(2x - 5) =

2x + 4 + 4x - 10 =

6x - 6

perimeter = 6x - 6

B:

(x+2)(2x - 5)            expand the brackets:

2x² - 5x + 4x - 10

area = 2x² - x - 10

C:

area = 6x - 6 = (6 x 5) - 6 = 30 - 6 = 24

perimeter = 2x² - x - 10 = (2 x 5²) - 5 - 10 = (2 x 25) - 5 - 10 = 50 - 5 - 10 = 35

Answer:

[tex]Probability = \frac{70}{143}[/tex]

Step-by-step explanation:

Given

[tex]Black = 5[/tex]

[tex]Red = 8[/tex]

[tex]Total = 13[/tex]

To solve the required probability, we need to determine the number of available selections:

There are two possible scenarios;

1: All 4 selections are red.

2. 1 selection is black, while 3 others are red

Scenario 1: All Red

[tex]^8C_4 = \frac{8!}{(8-4)!4!}[/tex]

[tex]^8C_4 = \frac{8!}{4!4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5*4!}{4!4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5}{4!}[/tex]

[tex]^8C_4 = \frac{8*7*6*5}{4*3*2*1}[/tex]

[tex]^8C_4 = \frac{1680}{24}[/tex]

[tex]^8C_4 = 70[/tex]

Scenario 2: 1 Black, 3 Red

Selecting Black:

[tex]^5C_1 = \frac{5!}{(5-1)!1!}[/tex]

[tex]^5C_1 = \frac{5!}{4!1!}[/tex]

[tex]^5C_1 = \frac{5*4!}{4!*1}[/tex]

[tex]^5C_1 = 5[/tex]

Selecting Red:

[tex]^8C_3 = \frac{8!}{(8-3)!3!}[/tex]

[tex]^8C_3 = \frac{8!}{5!3!}[/tex]

[tex]^8C_3 = \frac{8*7*6*5!}{5!3*2*1}[/tex]

[tex]^8C_3 = \frac{8*7*6}{6}[/tex]

[tex]^8C_3 = 8*7[/tex]

[tex]^8C_3 = 56[/tex]

Number of Selection = 5 * 56

[tex]Selection = 280[/tex]

Total Available Selection is calculated as thus:

[tex]Available\ Selection = 70 + 280[/tex]

[tex]Available\ Selection= 350[/tex]

Next, is to calculate the number of possible selections:

i.e 4 balls out of 13

This is calculated as:

[tex]^{13}C_4 = \frac{13!}{(13-4)!4!}[/tex]

[tex]^{13}C_4 = \frac{13!}{9!4!}[/tex]

[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10 * 9!}{9!4*3*2*1}[/tex]

[tex]^{13}C_4 = \frac{13 * 12 * 11 * 10}{4*3*2*1}[/tex]

[tex]^{13}C_4 = \frac{17160}{24}[/tex]

[tex]^{13}C_4 = 715[/tex]

[tex]Probability = \frac{Available\ Selection}{Possible\ Selection}[/tex]

[tex]Probability = \frac{350}{715}[/tex]

[tex]Probability = \frac{70}{143}[/tex]

Answer:

1) Shirt = $28.20  Jeans = $42

2) subtotal = $105.20

3) with the discount from the coupon, the pre-tax cost is $83.90

4) about $ 88.10 (actual answer was $88.095)

5) i have no clue bro, im sorry

Step-by-step explanation:

The sale price of the shirt  is [tex]\$28.20[/tex] The sale price of the jeans  [tex]\$42.00[/tex] Subtotal is [tex]\$[/tex]105.20 Pre-tax cost  [tex]\$78.90[/tex] The total amount charged with 5% sales tax is  [tex]\$42.00[/tex]

The sale price of the shirt:

Given -The original price of the shirt is $47, and it is on a "40% Off" sale. To find the sale price, we can calculate [tex]40\% of \$47[/tex]and subtract it from the original price:

The sale price of the shirt = [tex]\$47 - (40\% \times\$47)[/tex]

The sale price of the shirt =[tex]\$47 - (\$18.80)[/tex]

The sale price of the shirt =[tex]\$28.20[/tex]

The sale price of the jeans:

Given =The original price of the jeans is $60, and it is advertised as "30% Off." Similar to the shirt, we can calculate the sale price of the jeans:

The sale price of the jeans =[tex]\$60 - (30\% \times\$60)[/tex]

The sale price of the jeans =[tex]\$60 - (\$18.00)[/tex]

The sale price of the jeans = [tex]\$42.00[/tex]

Subtotal of the shirt, jeans, and shoes:

Subtotal = Sale price of the shirt + Sale price of the jeans + Sale price of the shoes

Subtotal = [tex]\$[/tex]28.20 + [tex]\$[/tex]42.00 +[tex]\$[/tex]35.00

Subtotal =[tex]\$[/tex]105.20

The pre-tax cost of your purchase with the[tex]25\%[/tex] off coupon:

The 25% off coupon is applied to the subtotal. We calculate 25% of the subtotal and subtract it from the subtotal to find the pre-tax cost:

Pre-tax cost = Subtotal -[tex](25\% \times Subtotal)[/tex]

Pre-tax cost = [tex]\$105.20 - (25\% \times \$105.20)\\[/tex]

Pre-tax cost =[tex]\$105.20 - (\$26.30)[/tex]

Pre-tax cost = [tex]\$78.90[/tex]

The total amount charged with 5% sales tax:

To calculate the total amount charged, we need to add the sales tax to the pre-tax cost:

Sales tax = [tex]5\% \times Pre-tax cost[/tex]

The Total amount charged = Pre-tax cost + Sales tax

The Total amount charged =[tex]\$78.90 + (5\% \times \$78.90)[/tex]

The total amount charged = [tex]\$78.90 + \$3.94[/tex]

The total amount charged =[tex]\$82.84[/tex]

Answer:

The value  is   [tex]n_2  = 317[/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n  =  73

   The proportion that in favor of raising the tuition is  [tex]\^{p} =  0.37[/tex]

   The standard deviation is  [tex]s_1  = 0.098[/tex]

    The required standard deviation  [tex]s_2  = 0.047[/tex]

Generally the requires standard deviation is mathematically represented as

      [tex]s_2  = s_1 *  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{s_2}{s_1}  =  \sqrt{\frac{n_1}{n_2} }[/tex]

=>    [tex]\frac{n_1}{n_2} =[\frac{s_2}{s_1} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =[\frac{0.047}{0.098} ]^2[/tex]

=>     [tex]\frac{73}{n_2} =0.2300[/tex]

=>     [tex]n_2 =  \frac{73}{0.2300}[/tex]

=>   [tex]n_2  = 317[/tex]
