Answer:

x positive, y negative

Step-by-step explanation:

ratelena [41]

Answer:

32+q

Step-by-step explanation:

<u><em>The complete question is</em></u>

Jake has 32 quarters on his desk, molly has q quarters in her purse.

Which algebraic expression represents the total number of quarters that Jake and Molly have?

we know that

To find out the total number of quarters that Jake and Molly have, sum the amount of quarters that Jake has plus the amount of quarters that Molly has

Let

x ----> the amount of quarters that Jake has

y ----> he amount of quarters that Molly has

so

x+y

we have

$x=32\ quarters\\y=q\ quarters$

substitute

32+q

Are they scaled copies or not? If so how do I find out?

Alenkinab [10]

1) <u>Find the length of the diagonals of the greater rhombus</u>

NJ=9 units

XY=6 units

Find the the ratio

NJ/XY=9/6-------> 3/2

2) <u>Find the length of the diagonals of the smaller rhombus</u>

HS=6 units

ZC=4 units

Find the the ratio

HS/ZC=6/4-------> 3/2

so

NJ/XY=HS/ZC--------> the rhombus are similar

the scale factor is equal to ------> 3/2=1.5

measure greater rhombus =scale factor*measure smaller rhombus

measure greater rhombus =1.5*measure smaller rhombus

measure smaller rhombus=(measure greater rhombus/1.5)

therefore

<u>the answer is</u>

Yes , they are a scaled copies and the scale factor is equal to 1.5

Of the range, the interquartile range, and the variance, the interquartile range is most influenced by an outlying value in the

amm1812

Answer:

Option B) False

Step-by-step explanation:

We define the following terms:

Range:

It is the difference between the minimum and maximum value of data.

It is effected by presence of outliers.

Interquartile range:

It is the difference between the third quartile and the first quartile of data.

Variance:

$\text{Variance} = \displaystyle\frac{\sum (x_i -\bar{x})^2}{n}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

It is a measure of spread of the data. It is effected by presence of outliers as they increase the variation in the data.

Thus, the given statement is false.

mezya [45]

Answer:

Closet #1.

Step-by-step explanation:

Closet #1 is 4x5x8, right? so, 4x5=20, and 20x8=160 feet. Closet #2 is 6x3x8, and 6x3 is 18. That's already less than 20 even before we multiply by 8. So, the answer to your question is Closet #1.
