Answer:
1=x4
Step-by-step explanation:
The probability is 56/100, or 14/25 = 0.56.
These events are not mutually exclusive, meaning they can happen at the same time. This means we use
P(A or B) = P(A) + P(B) - P(A and B)
P(carpool or full time) = P(carpool) + P(full time) - P(carpool & full time)
There are 6+9=15 people out of 100 that carpool.
There are 7+4+30+6=47 people out of 100 that work full time.
There are 6 people out of 100 that carpool and work full time.
This gives us
15/100 + 47/100 - 6/100 = 56/100
Answer:
Step-by-step explanation:
we know that
In the right triangle ABC
The function sine of angle 68 degrees is equal to divide the opposite side SB by the hypotenuse AC
so
substitute the values and solve for AC
Answer:
.5
Step-by-step explanation:
1 half of any thing is 50 percent and 50 percent is written as a decimal when you move the decimal point twice to the left giving you .5
Answer:
The weights within this range are:
8.9
9.5
9.8
10.4
Step-by-step explanation:
The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:
9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)
8.5 ≤ x ≤ 10.5
