both of the numbers are negative so the answer will be positive. and then you divide the two numbers
<em>It depends how many days you'ill watch the dog, but let's suppose you watch the dog for a week, Your friend #1 will pay you $10 + 2 Per day (10 + 2x = Y) and friend #2 will pay you $15 plus 1 per day ( 15 + 1x = y)
So a week has 7 days so you plug in 7 in "x"
Friend #1 = 10 + 2(7) = 24
Friend #2 = 15 + 1(7) = 22
I'll take friend #1 offer because it pays you more than friend #2.
Hope this answer helps!</em>
D. Is the one which has slope -3
It is because the point of it’s slopes are
( 0,0) and (1,-3)
So the slope will be
(Y2 - Y1)/(X2-X1)
Hence -3 is the slope of graph D.
First, 10 1/2 is the same as 21/2
If there are 12 inches in a foot then
21/2*12=126 inches
Answer:
b.(12.7350,16.5984)
Step-by-step explanation:
First, find the average and standard deviation of the sample:
x = 14.6667
s = 2.4618
To make a confidence interval of the population:
(μ ± MoE)
where:
μ = x
MoE = CV × s / √n
MoE is the margin of error, CV is the critical value, and s/√n is the standard error.
Looking in a student's t-table, for a 98% confidence interval, and for 12-1=11 degrees of freedom, CV = 2.718.
So the margin of error is:
MoE = 2.718 × 2.4618 / √12
MoE = 1.9316
The confidence interval is therefore:
(14.6667 ± 1.9316)
(12.7351, 16.5983)
