Okay add 78 and 66. Then add 96 and 108.  It should be 144 by 204. I know math  is hard, but when you work at it you can do amazing things! I hope that helps you.

Answer:

Area of new room = 14,616 in².

Step-by-step explanation:

Given : Elly's room measures 78 inches by 96 inches. Sarah's room measures 66 inches by 108 inches.

To find :  They want to combine their rooms. How large will the new room be?

.Solution : We have given that

Length of Elly room = 78 inches.

Width of Elly room =96 inches.

Area of Elly room = Length * width.

Area of Elly room = 78 * 96.

Area of Elly room  = 7488 in².

Length of Sarah room = 78 inches.

Width of Sarah room =96 inches.

Area of Sarah room = Length * width.

Area of Sarah room = 66 * 108.

Area of Sarah room  = 7128 in².

Combine their room = Area of Elly room + Area of Sarah room.

Area of new room = 7488 in² +  7128 in².

Area of new room = 14,616 in².

Therefore, Area of new room = 14,616 in².

Suppose Frances is a researcher at Beaded Gemsz, a company that makes beaded jewelry. She wants to evaluate whether using better
Natalija [7]

Answer:

There is 8% (P=0.08) that Frances concludes that the new equipment increases the average daily jewelry production when in fact the new equipment has no effect.

Step-by-step explanation:

We have one-sample z-test with a significance level of 0.08 and a power ot the test of 0.85.

In this test, the null hypothesis will state that the new equipment has the same  productivity of the older equipment. The alternative hypothesis is that there is a significative improvement from the use of new equipment.

The probability that Frances concludes that the new equipment increases the average daily jewelry production when in fact the new equipment has no effect is equal to the probability of making a Type I error (rejecting a true null hypothesis).

The probability of making a Type I error is defined by the level of significance, and in this test this value is α=0.08.

Then, there is 8% that Frances concludes that the new equipment increases the average daily jewelry production when in fact the new equipment has no effect.

The necklace charm shown has two parts, each shaped like a trapezoid with identical dimensions. What is the total area, in squar
pashok25 [27]
The area of the trapezoid can be calculated through the equation, 
                               A = (b₁ + b₂)h / 2
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given, 
                              A = (25mm + 32mm)(15 mm) / 2 
                               A = 427.5 mm²
Since there are two trapezoids in the necklace, the area calculated is to be multiplied by two to get the total area. 
                        total area = (427.5 mm²)(2) 
                        <em>total area = 855 mm²</em>

Find the difference: square root of 20 - square root of 80
Mamont248 [21]

Answer:

-2\sqrt{5}

Step-by-step explanation:

\sqrt{20} = \sqrt{10*2} = \sqrt{5 * 2 *2} = \sqrt{2^2 * 5} = 2\sqrt{5}   \\\\\sqrt{80} = \sqrt{20*4} = \sqrt{5*4 *4} = \sqrt{4^2 * 5} = 4\sqrt{5}   \\\\2\sqrt{5} - 4\sqrt{5} = -2\sqrt{5}
