Answer:

(143 ; 227)

Step-by-step explanation:

Mean , m = 185

Standard deviation, s = 14

Interval that would represent the middle 99.7%

According to the empirical rule, 99.7% represents 3 standard deviation from the mean

Mean ± 3(standard deviations)

185 - 3(14) = 185 - 42 = 143

185 + 3(14) = 185 + 42 = 227

A number decreased by the total of the number and fourteen
Charra [1.4K]

The answer to this would be x-(x+14)

Here's an explanation:

Let x represent the unknown number. The problem says that x has been decreased by the sum of x and 14. So, to put this in a form of an equation, it would be x-(x+14), since you have to do the addition first before you can subtract the two number since you don't know what x is. This equation is equal to -14 no matter what x is.

Find the sum or difference (5b-9)-3(8-2b)
True [87]
<span>Simplifying (5b + -9) + -3(8 + -2b) = 0 Reorder the terms: (-9 + 5b) + -3(8 + -2b) = 0 Remove parenthesis around (-9 + 5b) -9 + 5b + -3(8 + -2b) = 0 -9 + 5b + (8 * -3 + -2b * -3) = 0 -9 + 5b + (-24 + 6b) = 0 Reorder the terms: -9 + -24 + 5b + 6b = 0 Combine like terms: -9 + -24 = -33 -33 + 5b + 6b = 0 Combine like terms: 5b + 6b = 11b -33 + 11b = 0 Solving -33 + 11b = 0 Solving for variable 'b'. Move all terms containing b to the left, all other terms to the right. Add '33' to each side of the equation. -33 + 33 + 11b = 0 + 33 Combine like terms: -33 + 33 = 0 0 + 11b = 0 + 33 11b = 0 + 33 Combine like terms: 0 + 33 = 33 11b = 33</span>

A rectangular picture from has a length of 7 inches and a width
mezya [45]

Answer:

8.6

Step-by-step explanation:

This uses the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 7

c = ?

5^2 + 7^2 = c^2

25 + 49 = c^2

74 = c^2

sqrt(c^2) = sqrt(74)

c = 8.60 which when rounded = 8.6
