Answer:

Step-by-step explanation:
To find the slope, all we need is to points on the line.
Judging by that graph, we can see a point at (0,1) and at (5,4).
Simply enter this into the slope formula and you'll have your slope.

Your y1 term is 1, your y2 term is 4.
Your x1 term is 0, your x2 term is 5.

Your slope is
.
Answer:
A. (4.78, 6.90)
Step-by-step explanation:
Using the following formulas the lower and upper limits of the Interval are calculated
Lower limit = mean - (standard deviation /√sample size)* Zr
Upper limit = mean + (standard deviation /√sample size)* Zr
Zr depends on confidence interval and can be found in a z table
Zr for 90% = 1.645
then
Lower limit = 5.84 - (4.98 /√60)* 1.645 = 4.78
Upper limit = 5.84 + (4.98 /√60)* 1.645 = 6.90
Answer:
the correct answer is 5√30
Step-by-step explanation:
√20= 2√5
√3=√3
√18= 3√2
2√5 x √3 x 3√2= 5√30
