Answer:
(a)Mean=7 Hours
(b)Mean Absolute Deviation=2.5 Hours
Step-by-step explanation:
Given the number of hours of TV watched each week by 8 seventh grade students shown below.
11, 7, 9, 3, 3, 8, 10, 5
(a)Mean
(b)Mean absolute deviation
(c)The Mean Absolute Deviation tells us how far, on average, all values are from the mean. The Mean absolute deviation of 2.5 Hours tells us that each hour is on the average far from the mean number of hours by 2.5 Hours.
<span>2/3 of the rocks are metamorphic
</span><span>3/4 of the remainder are igneous rocks
</span><span>3 rocks left over are sedimentary
the rocks that deSean has are
2/3+3/4+3= 4x2+3x3/3x4 + 3 = 17+36 /12 = 20
</span><span>DeSean had 20 rocks </span>
Answer: the total lifetime cost for the loan is $11616.4
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total cost of the loan at the end of t years.
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount borrowed.
From the information given,
P = $5,500
r = 7.5% = 7.5/100 = 0.075
n = 12 because it was compounded 12 times in a year.
t = 10 years
Therefore,
A = 5500(1 + 0.075/12)^12 × 10
A = 5500(1 + 0.00625)^120
A = 5500(1.00625)^120
A = $11616.4
Answer:
-4
Step-by-step explanation:
Parallel lines have the same slope
If the green line has a slope of -4, then the red line has a slope of -4
Answer:
A frequency distribution table lists the data values, as well as the number of times each value appears in the data set. A histogram is a display that indicates the frequency of specified ranges of continuous data values on a graph in the form of immediately adjacent bars.
