Answer:
400 yd
Step-by-step explanation:
It's a 3 - 4 - 5 triangle
If the hypotenuse is a multiple of 5 and another length is the same multiple of 3 or 4, the one left over will be the same multiple of the one that's left.
Answer: C
Step-by-step explanation:
The value of x is 4
Step-by-step explanation:
The formula for simple interest is:

Here
P is principal amount
r is interest rate
and t is the time in years
We know
Interest = $840
Rate = r = 5%
P = $4200
Putting the values in the formula

Hence,
The value of x is 4

Answer:
The probability that the sample proportion will be greater than 13% is 0.99693.
Step-by-step explanation:
We are given that a large shipment of laser printers contained 18% defectives. A sample of size 340 is selected.
Let
= <u><em>the sample proportion of defectives</em></u>.
The z-score probability distribution for the sample proportion is given by;
Z =
~ N(0,1)
where, p = population proportion of defective laser printers = 18%
n = sample size = 340
Now, the probability that the sample proportion will be greater than 13% is given by = P(
> 0.13)
P(
> 0.13) = P(
>
) = P(Z > -2.74) = P(Z < 2.74)
= <u>0.99693</u>
The above probability is calculated by looking at the value of x = 2.74 in the table which has an area of 0.99693.
