Answer:
52 should be the answer
Step-by-step explanation:
first, love the parathesis. subtract 7-2
second 3 raised to the second power
third times 3 raised to the third power by 5 the answer a few u substrates 7-2
fourth 14 divide 2
finally I would add (14/2) 7 + 45 (which is 9 times 5)
read through it carefully by the end if the problem, you should have 52 as the ans
Answer:
C. -2
Step-by-step explanation:
To find the slope of the line we take two points
((0,1) and (2, -3)
and use the formula for slope
m= (y2-y1)/ (x2-x1)
= (-3-1)/(2-0)
= -4/2
= -2
Answer:
x > 4 for an inequality :)
Step-by-step explanation:
Answer:
A. mean=14.29
median=16
B. IQR=10
C. option 3
D. 5.91
Step-by-step explanation:
mean=sum of values/number of values=10+20+4+13+21+16+16/7=14.29
median is achieved by arranging data in increasing order and then calculating the middle value
4 10 13 16 16 20 21
The mid value is 16 so the median=16
IQR=interquartile range=3rd quartile-1st quartile=Q3-Q1=20-10=10
As n/4=7/4 is not an integer so
Q1=(n/4+1)value=(7/4+1)=2.75=2nd value=10
Q3=(3n/4+1)value=6.25=6th value=20
Standard deviation=s=sqrt(∑(x-xbar)²/n-1)=sqrt(209.43/6)=5.91
