Answer:
y = m x + b standard form of equation for straight line\
m = (y2 - y1) / (x2 - x1) = (20 - -8) / 17 - 1) = 28 / 16
m = 7 / 4
Answer:
Volume = 18 cm^3
Surface Area = 58 cm^2
Step-by-step explanation:
Find the volume with the formula V=w*h*l
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
V= w*h*l
V= 2cm * 1 cm * 9cm
V= 18 cm^3
Find the surface area with the formula A= 2(w*l + h*l + h* w)
W= width
H = height
L = length
W= 2cm
H= 1 cm
L= 9 cm
A= 2(w*l + h*l + h* w)
A= 2(2cm*9cm + 1cm*9cm + 1cm* 2cm)
A= 2(29cm)
A= 58cm^2
It is already rounded so you wont have to do anything.
6, Bob will have 6 apples after he gives 14 away.
To solve this problem, we must first understand what it is asking. Since Bob is giving away apples, he is subtracting them from his total amount. So, now we do the subtraction.
20 - 14 = 6, so Bob will have 6 apples after he gives 14 away.
Answer:
4.038
Step-by-step explanation:
The simple regression model is:
, then 
.
The statistic calculated for the hypothesis test of statistical significance, for the slope, in a simple regression model is given by:
with 
the slope estimator, 
the value of slope in the null hypothesis and 
the standard error of the slope. Thus,
