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.

What is the equation of the graph below?

oee [108]

Answer:

B) $y=-(x-3)^{2}+2$

Step-by-step explanation:

We are given,

The graph of the parabola opens downwards.

This means that the leading co-efficient of the function will be negative.

So, options C and D are not possible.

Moreover, it is given that the graph cuts x-axis near $1\frac{1}{2}$ i.e. $\frac{3}{2}$ = 1.5 and $4\frac{1}{2}$ i.e. $\frac{9}{2}$ = 4.5.

i.e. At y=0, the value of x is near $\frac{3}{2}$ and $\frac{9}{2}$ .

A. So, in $y=-(x+2)^{2}+2$ , we put y =0.

i.e. $(x+2)^{2}=2$

i.e. $x=-2\pm \sqrt{2}$

i.e. x = 0.68 and x = 3.41

We see that this does not crosses the x-axis at the given points.

So, option A is wrong.

B. Also, in $y=-(x-3)^{2}+2$ , we put y =0.

i.e. $(x-3)^{2}=2$

i.e. $x=3\pm \sqrt{2}$

i.e. x = 1.68 and x = 4.41.

Thus, this equation cuts the x-axis near the given points i.e. 1.5 and 4.5.

Hence, the equation of the given graph is $y=-(x-3)^{2}+2$ .

Ron is selling items at a craft show. The first hour his sales are $20. His sales grow by 10% each hour. What are Ron's total sa

solong [7]

C. $122.10. You take 20, then take 10 percent of that to find the second hour's earnings (which is $22), then you take 10% of that number to find the next hour's earnings, and so on and so on until you reach the 5th hour. When you add all the values up, you get $122.10.
