Answer:

Option C. $64\ cm^2$

Step-by-step explanation:

see the attached figure N 1 to better understand the problem

we know that

The trapezoid can be decomposed into two right triangles and a rectangle

see the attached figure N 2

The area of the trapezoid is equal to the area of two right triangles and one rectangle

The area of trapezoid is equal to

$A=\frac{1}{2}(5)(4)+(12)(4)+\frac{1}{2}(3)(4)$

$A=10+48+6$

$A=64\ cm^2$

Find the -scores that bound the middle 96 of the area under the standard normal curve by using the TI-84 calculator.

Korvikt [17]

Answer:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

Step-by-step explanation:

For this case we want to find the limits with the middle 96% of the area below the normal curve, then the significance level would be:

$\alpha=1-0.96 =0.04$

And $\alpha/2= 0.02$ and if we use the following function on the Ti84 plus we got:

invNorm(0.02,0,1)

invNorm(1-0.02,0,1)

And the values with the middle 96% of the values are:

$z_{\alpha/2}= \pm 2.054$

A triangle with two congruent sides is always a 45-45-90 triangle

Yanka [14]

The statement above is false, as a triangle with two congruent sides <em /><em></em>IS NOT ALWAYS a 45-45-90 triangle, however, it can be.

Hope this helps!

A sneaker company can make 50 pairs of sneakers for every 6 yards of material. Make a table to show the relation between materia

Law Incorporation [45]

A sneaker company can make 50 pairs of sneakers for every 6 yards of material.

Then in each case you can consider proportion.

1. 50 pairs -- 6 yards,

80 pairs -- x yards.

Mathematically,

$\dfrac{50}{80}=\dfrac{6}{x},\\ \\x=\dfrac{80\cdot 6}{50}=9.6\ yards.$

2. 50 pairs -- 6 yards,

100 pairs -- x yards.

Mathematically,

$\dfrac{50}{100}=\dfrac{6}{x},\\ \\x=\dfrac{100\cdot 6}{50}=12\ yards.$

3. 50 pairs -- 6 yards,

120 pairs -- x yards.

Mathematically,

$\dfrac{50}{120}=\dfrac{6}{x},\\ \\x=\dfrac{120\cdot 6}{50}=14.4\ yards.$

4. 50 pairs -- 6 yards,

140 pairs -- x yards.

Mathematically,

$\dfrac{50}{140}=\dfrac{6}{x},\\ \\x=\dfrac{140\cdot 6}{50}=16.8\ yards.$

Thus, the table is

$\begin{array}{cc}\text{Pairs}&\text{Yards}\\50&6\\80&9.6\\100&12\\120&14.4\\140&16.8\end{array}$

The domain of the relation is the set $\{50,80,100,120,140\}$ and the range of the relation is $\{6,9.6,12,14.4,16.8\}.$ See attached diagram for the graph of the relation.
