This expression is the difference of two squares.

It can be rewritten as (x/9)^2 - (y/10)^2.

The factors are     [(x/9) - (y/10)] [(x/9) + (y/10)].

The stem plot shows the number of sit-ups completed by a group of gym members in one minute. Row1 with a 1 to the left of the ba
allochka39001 [22]

Answer:

Only statement second is correct about the distribution.

Step-by-step explanation:

The stem plot data given to us is;

1 | 9

2 | 5

3 | 4   6   8   8

4 | 0   3   6   7   7

5 | 0   0   1    2

As it is given in the question that 1 | 9 = 19 sit-ups, so the data value are;

19, 25, 34, 36, 38, 38, 40, 43, 46, 47, 47, 50, 50, 51, 52

(a) The first statement that there is one outlier in the distribution is false as there are two outliers in the data (19 and 25) as they are very far from the rest of the data.

(b) The statement that the distribution is skewed left is correct because the tail of the distribution is towards the left.

(c) The statement that the center is around 47 is false as the center or mean of the data is 43 because the middle most data value is 43.

(d) The statement that the distribution is bimodal is false as there are is three modes in the data (38, 47 and 50), so the given distribution is trimodal.

Consider the diagram.

The congruence theorem that proves that △LON ≅ △LMN is: A. SSS congruence theorem

<h3>What is the SSS Congruence Theorem?</h3>

According to the SSS congruence theorem, if all three corresponding sides of two triangles are congruent, then both triangles are congruent.

In the image given, we have:

  • ON ≅ MN
  • LO ≅ LM
  • LN ≅ LN (reflexive property)

This means all three corresponding sides are congruent, therefore, the congruence theorem that proves both triangles are congruent is:

A. SSS.

Ian​'s car can go 93 miles on 3 gallons of gas. During a drive, last​ weekend, Ian used 8 gallons of gas. How far did Ian ​drive
Anuta_ua [19.1K]

Answer:248

Step-by-step explanation:

First you need to find the unit rate by dividing 93 by 3 which would be 31 then take that number (which is how many miles for one gallon) and multiply it by 8 which would get you 248( if you need this as an equation here 93\3= 31 31*8 = 248). If they gave you the distance instead you would have had to divide by 31 instead of using multiplication. Hope this helps!
