Answer:
2(2x+1)(4x−3)
Step-by-step explanation:
GCF = 2
2( 16x^ 2/ 2+−4x/2− 6/2)
2(8x ^2−2x−3)
2(8x ^2 +4x−6x−3)
2(4x(2x+1)−3(2x+1))
2(2x+1)(4x−3)
Answer:
Step-by-step explanation:
<u>Complete Question:</u>
Angela shared a cab with her friends . When they arrived at their destination, they evenly divided the $48 fare among "j" of them . Angela gave the cab $5 tip. How much did Angela pay in total?

First things first. 7/8 x 4/5 is 28/40=7/10. It is smaller than both numbers. When multiplying fractions, the answer gets smaller and smaller. The answer of multiplying fractions will always be smaller than both factors because you are multiplying a number less than 1 so it just gets smaller and smaller. That’s the best I can explain it. Sorry:)
The confidence interval for mean is
.
Here .
Use standard normal distribution table.
The z value to be used is such that
z=-1.96
The z value to be used is 1.96.
It is the first one I can’t explain it but yea it’s the first choice.
