A survey found that women’s heights are normally distributed with mean 63.8 in and a standard deviation 2.3 in. A branch of the military requires women’s heights to be between 58 in and 80 in.a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements? The percentage of women who meet the height requirement is __%. For the new height requirements, this branch of the military requires women’s heights to be at least __ in and at most __ in.
(-15b - 7) - (-2b)
Answers
Answer:
13b + 7
Step-by-step explanation:
Combine like terms. (-15b - 7) - (-2b), add -15b to both sides, the equation then becomes (-7) - (13b). Swap the equation around to become (13b) - (-7), a subtraction sign and then a negative makes the negative a positive. The equation then becomes 13b + 7.

To add the polynomials, combine like terms by adding the coefficients. The sum of the polynomials is 4x^3 - 3x^2 + x - 8.
Explanation:
To add the polynomials 3x^3+4x^2-x+8 and x^3-7x^2+2x-16, we combine like terms. We add the coefficients of the terms with the same degree of x.
Starting with the terms with degree 3, we have 3x^3 + x^3 = 4x^3.
Continuing with the terms with degree 2, we have 4x^2 - 7x^2 = -3x^2, and for the terms with degree 1, we have -x + 2x = x. Lastly, for the terms with degree 0 or the constant terms, we have 8 - 16 = -8.
Therefore, the sum of the polynomials is 4x^3 - 3x^2 + x - 8.

Answer:
You have a number multiplied by the variable x, so three times some value x. then you have (-y) taking the value of 3x and subtracting the value of (y) from it. The expression depends on the values of x and y you plug into it.
Step-by-step explanation:
for example, 3(4) - (6) = 12-6 = 6
