Answer:
(y+1)
Step-by-step explanation:
use quadratic formula.
you will get two values of y
y= 7/5 and y= -1
u can create factors using these values of y (making 0 subject)
like
for 7/5
7/5=y
7=5y
5y-7=0
zero becomes subject in such cases bcz there are no numbers left on that side
now for -1
-1=y
y+1=0
so your factors are 5y-7 and y+1
Answer:
9.18%
Step-by-step explanation:
First, find the z-score.
z = (x − μ) / σ
z = (18 − 19.6) / 1.2
z = -1.33
Use a chart or calculator to find the probability:
P(Z < z) = 0.0918
Answer:
The jogger will burn 277.5 calories
Answer:
0.05
Step-by-step explanation:
divide 100 by 20
<u><em>PART A</em></u>
If 4 pounds = 10 dollars...
4/2 = 2
10/2 = 5
<u>So for 2 pounds, it would cost </u><u>$5.00</u>
Now for the 1 pound one
4/1 = 4
10/4 = 2.5
<u>For the 1 pound one, it would cost </u><u>$2.50</u>
<u></u>
<u><em>PART B</em></u>
We know that 4 pounds = 10 bucks
Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, <u>$1 = 0.4lb</u>
Now for the last blank...
Since $1 = 0.4, we multiply that by 9. 0.4 x <u>$9 = 3.6lb</u>
<u></u>
