Answer:
False
Step-by-step explanation:
3+2=5
3+2=55-1=4
3+2=55-1=44x4=16
3+2=55-1=44x4=16Hence, the equation is true.
Answer:
a) I used the equation x=-5; f(x)=-11 and x=-4; f(x)=-3. We get the range = -3-(-11)=8
b) I used the equation x=-5; f(x)=-11 and x=-3; f(x)=5. We get the range = 5-(-11)=16
c) I used the equation x=-5; f(x)=-11 and x=-2; f(x)=13. We get the range = 13-(-11)=24
d) Range of input is equal with the ratios of the output. You can find the pattern of output above 8,16,and 24 can divided by 8 and give the result 1,2 and 3
Answer:
0.5358
Step-by-step explanation:
Given
mean = μ = 13.2 inches
and
SD = σ = 2.2 inches
We have to find z-score for the given value 13.4 first
z-score = (x-μ)/σ
= (13.4-13.2)/2.2
=0.2/2.2
=0.0909
We have to find the area to the left of given z-score
The area to the left is 0.5358
So, the probability of choosing an item with length less than 13.4 is 0.5358 ..
Answer:
A parallel y = 3x-1
B perpendicular y = -1/3x+9
Step-by-step explanation:
y = 3x-4 is written in slope intercept form (y=mx+b) so the slope is 3.
A. If the lines are parallel they have the same slope
m parallel is 3
Using point slope form
y-y1 = m(x-x1)
y-8 = 3(x-3)
Distribute
y-8 = 3x-9
Add 8 to each side
y-8+8 = 3x-9+8
y = 3x-1
This is slope intercept form
B If we want perpendicular lines, the slope is the negative reciprocal
m perpendicular is -(1/3) = -1/3
Using point slope form
y-y1 = m(x-x1)
y-8 = -1/3(x-3)
Distribute
y-8 = -1/3x+1
Add 8 to each side
y-8+8 = -1/3x+1+8
y = -1/3x+9
This is slope intercept form
