Answer:

Option C, 92 degrees

Step-by-step explanation:

<u>These angles are supplementary which means that they add up to 180 degrees.</u>

<u />

88 + x = 180

<u>Solve for x:</u>

88 + x - 88 = 180 - 88

x = 92

Elizabeth wants to use a sheet of fiberboard 27 inches long to create a skateboard ramp with a 17^{\circ}

erma4kov [3.2K]

The height of the ramp above the ground from its highest end is 7.9 inches.

<h3>What is height?</h3>

Height is the vertical distance between two points.

To calculate the height of the ramp above the ground, we use the formula below.

Formula:

h = Lsin∅............. Equation 1

Where:

h = Height of the ramp above the ground
L = Length of the fiberboard
∅ = Angle of elevation from the ground

From the question,

Given:

L = 27 inches
∅ = 17°

Substitute these values into equation 1

h = 27×sin17°
h = 7.89
h ≈ 7.9 inches

Hence, the height of the ramp above the ground is 7.9 inches.

Family Video charges $10 for

Irina18 [472]

Answer:

4 movies, $20

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20

The sum of 5 times a number and <br> minus −2, plus 7 times a number

Olenka [21]

Answer:

12x + 2

Step-by-step explanation:

Let the number be represented by x.

Then five times the number = 5*x

Seven times the number = 7*x

Sum of 5 times the number minus -2 = $5*x - (-2)$ = $5x +2$

Adding seven times the number to this expression yields, $5x+2+7x$

$= (5+7)x+2$

$= 12x+2$

So the simplified expression corresponds to 12x + 2.

According to the National Vital Statistics, full-term babies' birth weights are Normally distributed with a mean of 7.5 pounds a

Sav [38]

Answer:

68.26% probability that a randomly selected full-term pregnancy baby's birth weight is between 6.4 and 8.6 pounds

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 7.5, \sigma = 1.1$
