Hey!

------------------------------------------------

Solve for A:

A = 3.6 * (3/4 + 2/9 + 5/12)

A = 3.6 * (27/36 + 8/36 + 15/36)

A = 3.6 * (50/36)

A = 18/5 * 50/36

A = 900/180

A = 5

Answer:

A = 5

------------------------------------------------

Solve for B:

B = (84.8 * 0.125) ÷ (10.07 ÷ 0.95)

B = 10.6 ÷ 10.6

B = 1

Answer:

B = 1

------------------------------------------------

Solve for C:

$C = (1 \frac{5}{12} - \frac{2}{3} ) / 0.15 + \frac{(14 - 0.14) / 0.014}{99}$

$C = (1\frac{5}{12} - \frac{8}{12}) / 0.15 + 10\\C = (\frac{9}{12}) / 0.15 + 10 \\C = 5 + 10\\C = 15$

Answer:

C = 15

------------------------------------------------

Solve for D:

D = 0.28 * 4,500 ÷ 35 * 1/12

D = 1,260 ÷ 35 * 1/12

D = 36 * 1/12

D = 3

Answer:

D = 3

------------------------------------------------

Data Set:

1, 3, 5, 15

------------------------------------------------

Final Answer:

A proportion cannot be made by these numbers.

Find the value of w (u(2))

katrin [286]

<h3>Answer: 17</h3>

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

Explanation:

We'll start things off by computing the inner function u(2)

Plug x = 2 into the u(x) function

u(x) = -x-1

u(2) = -2-1

u(2) = -3

This tells us that w(u(2)) is the same as w(-3). I replaced u(2) with -3.

We'll plug x = -3 into the w(x) function

w(x) = 2x^2-1

w(-3) = 2(-3)^2 - 1

w(-3) = 2(9) - 1

w(-3) = 18-1

w(-3) = 17

Therefore, w(u(2)) = 17

------------------------

Here's a slightly different approach:

Let's find what w(u(x)) is in general

w(x) = 2x^2 - 1

w(u(x)) = 2(u(x))^2 - 1

w(u(x)) = 2(-x-1)^2 - 1

Then we can plug in x = 2

w(u(x)) = 2(-x-1)^2 - 1

w(u(2)) = 2(-2-1)^2 - 1

w(u(2)) = 2(-3)^2 - 1

w(u(2)) = 2(9) - 1

w(u(2)) = 18 - 1

w(u(2)) = 17

Solve the equation. Y/8+4=13

Troyanec [42]

Answer:

Y =72

Step-by-step explanation:

Y/8+4=13

Subtract 4 from each side

Y/8+4-4=13-4

Y/8 = 9

Multiply by 8

Y/8*8 = 9*8

Y =72

Suppose the owner of a local apple orchard has 4 half-bushels of apples to sell. He loads them on his truck, and drives his rout

NikAS [45]

Answer:

a) The orchard owner's expected profit from driving the route is $33.

b) The standard deviation of the profit is $27.28

Step-by-step explanation:

a) Data and Calculations:

Apples to sell = 4 half-bushels

Price of each half-bushel sold = $40

Sales revenue = $160 ($40 *4)

Cost of driving the route = $15

Expected values:

Event Probability Revenue Profit Expected Profit

No Sales 40% $0 ($15) ($0 - $15) ($6.00)

Selling 1 half-bushel 30% $40 $25 ($40 - $15) $7.50

Selling 2 half-bushels 10% $80 $65 ($80 - $15) $6.50

Selling 3 half-bushels 10% $120 $105 ($120 - $15) $10.50

Selling 4 half-bushels 10% $160 $145 ($160 - $15) $14.50

Total expected profit = $33

Event Expected Profit Mean Squared

Difference

No Sales ($6.00) -39 1,521

Selling 1 half-bushel $7.50 -25.5 650.25

Selling 2 half-bushels $6.50 -26.5 702.25

Selling 3 half-bushels $10.50 -22.50 506.25

Selling 4 half-bushels $14.50 -18.50 342.25

Sum of squared differences 3,722

Mean of squared differences = 744.4 (3,722/5)

Standard deviation = square root of the mean

= 27.28

= $27.28
