First, we need to find 8% of 1,575. To do so we have to divide 8 by 100, then multiply the quotient by 1,575.

8% ⇒ 0.08

1,575 × 0.08 = 126

Now add the 8% increase to the original cost.

1,575 + 126 = 1,701

<h2>Answer:</h2>

<u>Option 1: </u><u>$1,701</u><u>.</u>

I hope this helps :)

A line passes through (3, 7) and (6, 9). Which equation best represents the line? (4 points) y = 3 over 2 x + 5 y = 2 over 3 x +
kotykmax [81]

Given two points, the equation of the line may be determined by,

y - y1 = ((y2 - y1) / (x2 - x1))(x - x1)

Substituting the given values,

y - 7 = ((9 - 7) / (6 - 3))(x - 3)

Simplification will yield to an answer of,

y = 2x/3 +5

Therefore, the answer is the second choice.

Historical data for a local steel manufacturing company shows that the average number of defects per standard sheet of steel is
Yanka [14]

Answer:

Therefore the correct answer is A.) 84.88%

Step-by-step explanation:

i) λ = 2

ii) λ for three units = 2 \times 3 = 6

iii) P(x ≥ 4) = 1 - P(x < 4) = 1 - {P(x = 0) + P(x = 1) + P(x = 2)  + P(x = 3) }

                                = 1 - { \frac{e^{-6}6^{0} }{ 0!} + \frac{e^{-6}6^{1} }{ 1!}  + \frac{e^{-6}6^{2} }{ 2!} + \frac{e^{-6}6^{3} }{ 3!}  }

                                = 1 - (0.0025 + 0.0149 + 0.0446 + 0.0892)

                                = 0.8488

 Therefore the correct answer is A.) 84.88%

Can someone answer this for me?

<h3>Answers:</h3><h3>Total Area = 342.5 square meters</h3><h3>Total Cost = 138 pounds</h3>

=============================================================

Work Shown:

Break the figure up as shown by the dashed lines. Think of cutting along those lines to form 3 separate figures. The trapezoid on the left has area

A = h*(b1+b2)/2

A = 5*(11+12)/2

A = 57.5

The rectangle in the middle has area

A = L*W

A = 12*15

A = 180

The trapezoid on the right has area

A = h*(b1+b2)/2

A = 10*(12+9)/2

A = 105

Overall, the entire figure has area of 57.5+180+105 = <u>342.5 square meters</u>

1 can costs £6 and it covers 15 square meters. We need to cover 342.5 square meters

342.5/15 = 22.8333333333333 approximately

Round up to the nearest whole number to get 23

We need 23 cans to be able to paint 342.5 square meters or more

Note that 22 cans won't be enough because 22*15 = 330 is short of 342.5

While 23 cans is more than enough since 23*15 = 345. It's better to have leftovers than come up short.

Since each can costs £6 and we need 23 of them, the total cost would then come to 6*23 = <u>138 pounds</u>
