20 and 28 can be divided by 4, so just take the 4 out so the answer should be 4(5x - 7)
Answer:
The value of the expression 2*-2-(3- -2) is -9.
Step-by-step explanation:
2 x (-2)- (3- -2)
=2 x (-2)- (3+2)
=2 x (-2) -5
= -4-5
=<u><em>-9</em></u>

Answer:
15/2
Step-by-step explanation:
5 3/4 - 1/6x = 4 1/2
move the variable to it's own side.
5 3/4 - 4 1/2 = 1/6x
change the subtracting side to have common denominators
5 3/4 - 4 2/4 = 1/6x
1 1/4 = 1/6 x
divide both sides by 1/6, same thing as multiplying both sides by 6 (reciprocal)
30/4 = x
reduce: 15/2 = x
Answer:
<h2>NONE OF THEM</h2>
Step-by-step explanation:
From the graph,
y and x intercepts are
and approximately
respectively
for A, C and D : 
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are
and approximately
respectively
for B: 
x and y intercepts are
and approximately
respectively
Therefore x and y intercepts for the lines
and
they are not equal to the x and y intercepts of the given graph
Answer: 0.9862
Step-by-step explanation:
Given : The probability that the chips belongs to Japan: P(J)= 0.36
The probability that the chips belongs to United States : P(U)= 1-0.36=0.64
The proportion of Japanese chips are defective : P(D|J)=0.017
The proportion of American chips are defective : P(D|U)=0.012
Using law of total probability , we have

Thus , the probability that chip is defective = 0.0138
Then , the probability that a chip is defect-free=
