we know that

The midsegment of a trapezoid is the segment connecting the midpoints of the two non-parallel sides of the trapezoid, and is parallel to the pair of parallel sides.

In this problem

the two non-parallel sides of the trapezoid are AD and BC

Step 1

Find the midpoint side AD

Let

E-------> the midpoint AD

A(2,4)\ D(-2,-1)

Find the x-coordinate of the midpoint AD

x=\frac{2-2}{2}=0

Find the y-coordinate of the midpoint AD

y=\frac{4-1}{2}=1.5

the point E is equal to (0,1.5)

Step 2

Find the midpoint side BC

Let

F-------> the midpoint BC

B(7,4)\ C(9,-1)

Find the x-coordinate of the midpoint BC

x=\frac{9+7}{2}=8

Find the y-coordinate of the midpoint BC

y=\frac{4-1}{2}=1.5

the point F is equal to (8,1.5)

Step 3

Find the distance EF

we know that

The formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

E(0,1.5)\ F(8,1.5)

substitute the values

d=\sqrt{(1.5-1.5)^{2}+(8-0)^{2}}

d=8\ units

therefore

<u>the answer is</u>

the length of the midsegment of the trapezoid is 8\ units

I believe it is 8 because EF= \frac{AB+CD}{2} = EF= \frac{5+11}{2} =8

Question Progress Homework Progres 23/2 Solve the quadratic equation 3x + x-5 = 0 Give your answers to 2 decimal places.​
kykrilka [37]

The value of x is 1.14 or x = -1.47

We find the value of x in the quadratic equation 3x^2 +x-5=0

Using the formula: (-b ± √ (b²- 4 a c)) / (2a)

Where the value of a = 3, b = 1 and c = -5

Substituting the above values (a = 3, b = 1 and c = -5)

in the formula:

(-1 ± √ (1²- 4 3 (-5))) / (2*3)

= (-1 ± √ (1+60)) / (6)

= (-1 ± √ (61)) / (6)

= (-1 ± 7.81) / (6)

= (-1 + 7.81) / (6) or (-1 -7.81) / (6)

= (6.81) / (6) or (-8.81) / (6)

=1.135 or -1.468

Hence the value of x= 1.14 or -1.47

An art history professor assigns letter grades on a test according to the following scheme. A: Top 13% of scores B: Scores below
madam [21]

Answer:

The numerical limits for a B grade are 81 and 89, that is, a score between 81 and 89 gets a B grade.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score 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 p-value, we get the probability that the value of the measure is greater than X.

Scores on the test are normally distributed with a mean of 79.7 and a standard deviation of 8.4.

This means that \mu = 79.7, \sigma = 8.4

B: Scores below the top 13% and above the bottom 56%

So between the 56th percentile and the 100 - 13 = 87th percentile.

56th percentile:

X when Z has a p-value of 0.56, so X when Z = 0.15. Then

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

0.15 = \frac{X - 79.7}{8.4}

X - 79.7 = 0.15*8.4

X = 81

87th percentile:

X when Z has a p-value of 0.87, so X when Z = 1.13.

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

1.13 = \frac{X - 79.7}{8.4}

X - 79.7 = 1.13*8.4

X = 89

The numerical limits for a B grade are 81 and 89, that is, a score between 81 and 89 gets a B grade.
