Step-by-step explanation:
<u>John</u>
1hour=x
6x=150
X=150÷6=25
John earns 25 dollars per hour
<u>Peter</u>
<u>1hour=x </u>
<u>8</u><u>x=</u><u>160</u>
<u>X=</u><u>160</u><u>÷</u><u>8</u><u>=</u><u>20</u><u> </u>
- Peter earns less than <u>John</u><u> </u>
umm ,this is too long could you maybe putt it in smaller form so I can answer
Answer:
0.1611
Step-by-step explanation:
Uaing the binomial probability relation :
p = 0.5 ; q = 1 - p = 0.5
n = 10
Using the relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 7) = 10C7 * 0.5^7 * 0.5^3
P(x = 7) = 0.1172
x = 8 ;
P(x = 8) = 10C7 * 0.5^7 * 0.5^3
P(x =8) = 0.0439
P(x = 7 or x = 8) = 0.1172 + 0.0439 = 0.1611
Answer:
15000
Step-by-step explanation:
0.4%=0.004
0.004x=60
