Answer:
a=-9 b=-5
Step-by-step explanation:
a(3-x) = - 2x+b
a3 - ax = - 2x+b
a3 - 2a = - 4+b
If you take a=-9
-27+18=-4+b
b= -5
Answer:
1. 2 2. 1 3.(2,1)
Step-by-step explanation:
y=_x+3
plug y in by choosing a number in the y column.
1=_x+3
1=(2)(-1)+3
1=1
Part 2.
do the same
5=3(2)
5=6-1
5=5
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that
Now we replace P(Y) * P(X) for P(Y∩X)
Cancel out P(X)
So 
Like that
Now we replace P(X) * P(Y) for P(X∩Y)
Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
Answer: A
Step-by-step explanation:
pretty sure :)
The total length of the bolts that are less than 1 inch long is 1 6/8 inches while the fraction of the bolts are greater than 1 inch long is 4/10
<h3>What is
line plot?</h3>
Line plot is a type of graph that is used to represent a group of data on a number line.
From the number line:
Length less than 1 in = 3/8 + 4/8 + 7/8 = 14/8 = 1 6/8 inches
Fraction of the bolts are greater than 1 inch long = 4 / 10
The total length of the bolts that are less than 1 inch long is 1 6/8 inches while the fraction of the bolts are greater than 1 inch long is 4/10
