Answer:

The answer would be C

Step-by-step explanation:

Since of course negative 5 is a negative and any negative number plus a positive number would end up being a negative number and that means that that would be the least since no other number is a negative. The square root of 132.... Can it be bigger than 7 5/16? Yeah. Because the Square root of 132, if rounded, it would be 11 which 11 is greater than 7 which would mean the correct order would be -5 x 10^2, 7 5/16, and the square root of 132.

kogti [31]

Answer:

5x^3 - 4x^2 + 6x - 7

Step-by-step explanation:

Given

f(x) = 2x^2 + 6x – 4
g(x) = 5x^3 – 6x^2-3

To find

(f +g)(x)

Solution

(f +g)(x) = f(x) + g(x) =
2x^2 + 6x - 4 + 5x^3 - 6x^2 - 3 =
5x^3 - 4x^2 + 6x - 7

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday. If the coach's friend jogs twice as far as t

Bond [772]

Answer:

Coach's friend jog 8.6 miles.

Step-by-step explanation:

Given:

A coach jogs 1.8 miles on Monday, 1.3 miles on Tuesday, and 1.2 miles on Wednesday.

If the coach's friend jogs twice as far as the coach.

Now, to find the miles the coach's friend jog.

Coach jogs on Monday = 1.8 miles.

Coach jogs on Tuesday = 1.3 miles.

Coach jogs on Wednesday = 1.2 miles.

Total miles coach jog = $1.8+1.3+1.2=4.3\ miles.$

As, coach's friend jogs twice as coach.

So, to get the miles coach's friend jogs multiply total miles coach jog by 2 we get:

$Total\ miles\ coach\ jog\times 2$

$4.3\times 2\\\\=8.6\ miles.$

Therefore, coach's friend jog 8.6 miles.

A fruit company has 20% returns in periods of normal rainfall and -3% returns in droughts. The probability of normal rainfall is

WARRIOR [948]

Answer:

$E(x) = 10.8\% \\\\$

The fruit company’s expected returns are 10.8%

Step-by-step explanation:

The expected returns of the fruit company is given by

$E(x) =\sum (x \cdot P(x)) \\\\$

For the given case,

Returns in normal rainfall = x₁ = 20% = 0.20

Returns in drought = x₂ = -3% = -0.03

Probability of normal rainfall = P(x₁) = 60% = 0.60

Probability of drought = P(x₂) = 40% = 0.40

So, the expected value of returns is

$E(x) = x_1 \cdot P(x_1) + x_2 \cdot P(x_2) \\\\E(x) = 0.20 \cdot 0.60 - 0.03 \cdot 0.40 \\\\E(x) = 0.12 - 0.012 \\\\E(x) = 0.108 \\\\E(x) = 10.8\% \\\\$

Therefore, the fruit company’s expected returns are 10.8%
