A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?
7
5
8
Answer:
8 has to be included in the data set. Since 8 is the mode, and the mode is the number that is seen the most in a set of numbers, 8 has to be in the data set for it to be the mode. Therefore, the answer is 8.

What is the interquartile range of warrens data?
Answer:
10
Step-by-step explanation:
Answer:
To find the interquartile range, first arrange the values in the data set in ascending order:
0, 5, 5, 10, 10, 10, 15, 15, 15, 20, 20, 20, 25, 25, 30.
Because there are 15 values in the data set, the first quartile is the 4th value, which is 10, and the third quartile is the 12th value, which is 20.
interquartile range
=
third quartile – first quartile
=
20 – 10
=
10
The interquartile range of Warren's data is 10.

The 25th term of the given arithmetic sequence is -19.
The given arithmetic sequence is 53, 50, 47, 44, 41.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is an=a+(n-1)d
Here the first term of the sequence is a=53 and the common difference is
50-53=-3
Put, a=53, d=-3 and n=25 in the general form an arithmetic sequence, we get
a25=53+(25-1)×(-3)
= 53+24×(-3)
= 53-72
= -19
Therefore, the 25th term of the given arithmetic sequence is -19.

Which equation can be used to find the value of x?
109=180
x+42=67
x=180-109
42+67-x=180
Answer:
C
Step-by-step explanation:
We know every triangle equals 180 so were just going to take 180 - 42 = 138 then were going to do 138 - 67 = 71 we can check our work by doing
42 + 67+ 71 = 180. We also know 67 + 42 = 109.
Lets look at our answers;
A. 109 = 180 + x When solved it gave me; x = -71. We got a positive 71 so this is incorrect.
B. x + 42 = 67 When solved it gave me; x = 25, which is incorrect.
C. x = 180 - 109 When solved it gave me; x = 71
D. 42 + 67 - x = 180 When solved it gave me; x = - 71
Therefore the answer is C.

M(-5,2) and N(5,2) are the endpoints of the sedment MN on the cordinate plane what is the length of MN
Answer:
10 units
Step-by-step explanation:
Given data
The points are
M(-5,2) and N(5,2)
x1=-5
y1= 2
x2=5
y2= 2
The expression for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
substitute
d=√((5-(-5))²+(2-2)²)
d=√10²+0²
d=√100
d=10
Hence the distance is 10 units

A survey reveals that the sales of smartphones is increasing considerably. The average annual sales of smartphones, in million units, n years after the survey is conducted is modeled by function p below. The parameter b is an unknown positive base.
p(n)=1.7×b^n
Which statement is true about this situation?
A.
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
B.
If b = 1.02, the annual sales of smartphones will double in 2 years.
C.
If b = 1.45, the annual growth rate of the sales of smartphones is 145%.
D.
The average annual sales of smartphones increases by 1.7 million units every year.
Answer:
When the survey was initially conducted, the average sales of smartphones was 1.7 million units.
Step-by-step explanation:
The exponential equation is P ( n ) = 1.7 ( b )ⁿ , where n is the number of years and P ( n ) is the annual sales of smartphones and the initial sales of smartphones was 1.7 million units
What is exponential growth factor?The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
P ( n ) = 1.7 ( b )ⁿ
where , n is the number of years
And , P ( n ) is the annual sales of smartphones
Now , the value of b is the exponential growth factor
At the initial year , the number of smartphones sold is when n = 0
So , when n = 0
P ( 0 ) = 1.7 ( b )⁰
P ( 0 ) = 1.7 million units
Hence , the number of smartphones sold in initial year is 1.7 million units
