Trapezoid area = ((sum of the bases) ÷ 2) • height
Trapezoid area = [(8.2 + 5.9) /2] * 10
Trapezoid area = (14.1 / 2) * 10
Trapezoid area =7.05 * 10
Trapezoid area = 70.50

Solve the inequality –1 > –2(x – 4) – 5(4x – 7).

Ksivusya [100]

Answer:

$x > 2$

Step-by-step explanation:

$–1 > –2(x – 4) – 5(4x – 7)$

$–1 > –2x + 8 –20x + 35$

$–1 > - 22x + 43$

$- 1 - 43 > - 22x$

$- 44 > - 22x$

$\frac{ - 44}{ - 22} < \frac{ - 22x}{ - 22}$

$2 < x$

$x > 2$

Titus is asked to prove hexagon FEDCBA is congruent to hexagon

Goshia [24]

Answer:

(x, y) -------> ( - x , y - 10 )

Step-by-step explanation:

Titus is not correct.

There are two transformations will correctly prove FEDCBA ≅ F'E'D'C'B'A'

First transformation is Reflection over y-axis , then translation 10 units down.

The final formula is ( - x , y - 10 )

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr

Alex Ar [27]

Answer:

3/68

Step-by-step explanation:

Given

Total 17 marbles
4 - blue marbles
6 - green marbles
2 - red marbles
The rest - yellow marbles

Probability of drawing red first:

P(red) = number of red / total number = 2/17

Probability of drawing green second, without replacement:

P(green) = number of green / number left in the bag = 6/16 = 3/8

Probability of red and green in order:

P = P(red)*P(green) = 2/17*3/8 = 3/68

Last year, the number of skateboards produced by a skateboard company is normally distributed. The standard deviation of skatebo

jenyasd209 [6]

The average number of skateboards produced per day last year is 310.

<h3>What is a normal distribution?</h3>

It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.

We have:

The standard deviation of skateboards produced was 20 skateboards. They found they produced up to 280 skateboards on 93.32% of the days last year.

Z- score at 93.32% is -1.5

We know:

$\rm Z = \dfrac{(x - \mu)}{\sigma}$

$\rm -1.5 = \dfrac{(280 - \mu)}{20}$

μ = 280 + 30

μ = 310

Thus, the average number of skateboards produced per day last year is 310.
