Alina [70]

ANSWER:

Carlos is building a screen door.The width of the screen is 3 feet.

SOLUTION:

Given, Carlos is building a screen door. The height of the door is 1 foot more than twice its width.

And height of the screen door is 7 feet high.

Let the width of the screen door be x feet wide.

Now, according to given information,

Height is 1 foot more than the 2 times of width. Hence we can form a equation as,

7 = 1 + 2x

2x = 7 – 1

2x = 6

x = $\frac{6}{2}$ = 3

Hence, the width of the screen is 3 feet.

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.

0 ft elevation, diver is underwater at depth of 138 ft. In this area, the ocean floor has a depth of 247 ft. A rock formations r

KiRa [710]

We know that the ocean floor has a depth of 247 ft, and we also know that the diver is underwater at depth of 138 ft, so its distance from the ocean floor will be:
 $247-138=109$ ft

Now, the rock formations rises to a peak 171 to above the ocean floor, so to find how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:
 $171-109=62$ ft

We can conclude that the diver is 62 feet below the top of the rock formations.
