Answer:

T = n represents the total amount of berries, in cups, that Emma, will put into the containers.

Step-by-step explanation:

Emma has n containers. She will put a cup of berries into each container.

Therefore, each of the n containers is filled with one cup of berries.

So, there will be (n × 1) = n cups of berries in total n container.

Hence, T = n represents the total amount of berries, in cups, that Emma, will put into the containers. (Answer)

Which Mean Absolute Deviation represents more consistency? 15.2 or 10.9

Firdavs [7]

Answer:

10.9

Step-by-step Explanation:

The Mean Absolute Deviation of a given data set tells us how far apart, on average, each data value is to the mean of the data set.

The smaller the Mean Absolute Deviation of a given data set is, the closer each data value is to the mean. This also implies less variability of the data set.

Invariably, the smaller the M.A.D, which connotes less variability, the more consistent the data set is.

Therefore, a M.A.D of 10.9 represents more consistency than a M.A.D of 15.2

The length of each side of an equilateral triangle is increased by 20%, resulting in triangle ABC. If the length of each side of

kompoz [17]

Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

$A=\frac{\sqrt{3} }{4} a^{2}$

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

$A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}$

$A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}$

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

$A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}$

$A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}$

Now, comparing areas:

$\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )$

$\frac{A_{1}}{A_{2}} =$ 2.25

The area of ΔABC is 2.25x greater than the area of ΔDEF.

Daniel is creating a scale drawing of her room. the rectangular room measures20 1/2 ft. by 25 ft. if her drawing uses the scale

zavuch27 [327]

1 in = 2 ft

20.5 ft = 10.25 in
25 ft = 17.5 in

8.5 in and 11 in. no, the drawing will not fit, because the proportions is larger than 8.5 in and 11 in.

hope this helps
