Answer:
0.938
Step-by-step explanation:
From the question :
p = 0.14
Number of children, n = 7
P(x ≤ 2) = P(2) + P(1) + P(0)
Using binomial probability :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
We could also use the binomial probability calculator :
P(x ≤ 2) = 0.3479 + 0.3965 + 0.1936
P(x ≤ 2) = 0.938
Well let's see, how about we subtract 6 P.M from 30 minutes and that is 5:30 P.M then we subtract 5:30 by 15 minutes, and we get 5:15 P.M then we subtract 5:15 P.m by 45 minutes and we get 4:30 P.M
Answer:
Step-by-step explanation:
jack=35
Hassan=x
x+35=255
255-35=$220 (It has to be x=)
So:
220/2=$110
Therefore:
Hassan=$110
Jack=$110+$35=$145 (because he had earned $35 more)
Answer:
14.24 foot far is the mirror from the base of the statue.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement:
See the diagram as shown below:
Height of a boy = 5.9 foot tall
Height of a statue = 12 foot.
Distance of a boy from the mirror = 7 feet.
Let x be the distance of the mirror from the base of the statue.
then by definition of proportion we have;

Substitute the given values we have;

By cross multiply we have;

Divide both sides by 5.9 we have;
x = 14.24 ft
Therefore, 14.24 foot far is the mirror from the base of the statue.
Answer:
x = -69.87
Step-by-step explanation:
22.5 + x = -47.37
Subtract the 22.5 on both sides:
x = - 69.87
