Pete adds 78 to the fata set below. 20,32,32,45,50. Which statement below will be true?
ozzi

Answer:

the inter-quartile range will increase

Step-by-step explanation:

The initial data-set was;

20,32,32,45,50

Adding a new value 78 will have several effects;

The mean of the new set of values will increase since 78 is mostly likely to be an outlier.

The median of the new data set will increase. The median of the old data set is 32 while that of the new data set will be 38.5

The mode is the most frequent observation. Both the new and the old sets of values will have a mode of 32. The mode will therefore remain the same.

The inter-quartile range just like the range will increase

Alicia shoots A basketball at a hoop hundred times. She hits the backboard and Misses with 2/5 of her shots, hit the rim and mis
g100num [7]

Answer:

28 baskets

Step-by-step explanation:

Total Shots = 100

Backboard and miss = 2/5 of total

That is:

\frac{2}{5}*100=40

Rim and miss = 32% of total

That is:

32% = 32/100 = 0.32

0.32 * 100 = 32 shots

So, miss = 40 + 32 = 72

The rest, she makes, so left:

100 - 72 = 28 shots

Alicia makes 28 baskets (from 100)

2 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!
Ivanshal [37]

Answer:

This series is divergent

F

Step-by-step explanation:

we are given a series

Firstly, we will find nth term

Numerator:

3, 4, 5,...

so, nth term will be

a_n=n+3

Denominator:

4,5,6,....

so, nth term will be

b_n=n+4

so, we can find it's nth term as

c_n=\frac{n+3}{n+4}

we can use divergent test

\lim_{n \to \infty}  c_n=\lim_{n \to \infty} \frac{n+3}{n+4}

we can divide top and bottom by n

\lim_{n \to \infty}  c_n= \lim_{n \to \infty} \frac{n/n+3/n}{n/n+4/n}

\lim_{n \to \infty}  c_n= \lim_{n \to \infty} \frac{1+3/n}{1+4/n}

now, we can plug n=inf

\lim_{n \to \infty}  c_n= \frac{1+0}{1+0}

\lim_{n \to \infty}  c_n=1

Since, it is non-zero value

so, this series is divergent

What is the answer??
Amanda [17]

Answer:

angle 1= 104                angle 2= 76

Step-by-step explanation:

angle 1 equals x+66 and angle 2 equals 2x so you set up an equation where they are the sum of 180 degrees because the angles are supplementry angles.

x+66+2x=180                        set the sum of the angles to 180

3x+66=180                            combind like terms

3x=144                                   subract 66 from both sides

x=38                                      divide 3 from both sides

Now you put x back into the measurments

angle 1= (x+66)                              angle 2= 2x

              (38+66)                                           2×38

angle 1= 104                                   angle 2= 76

Or after you know angle 1 you can subtract angle 1 from 180 to get angle 2.
