25.25 bc 76 divided by 5 because the answer will not go evenly so you have to have a decimal
Answer:
The correct option is (d) 21.19%.
Step-by-step explanation:
Let the random variable <em>X</em> denote the heights of Fernando's peers.
The mean and standard deviation of the random variable <em>X</em> are:
<em>μ</em> = 68 inches
<em>σ</em> = 10 inches
It is provided that Fernando is 60 inches tall.
Compute the value of P (X < 60) as follows:
*Use a <em>z</em>-table.
The percentage is, 0.2119 × 100 = 21.19%.
Thus, the percentage of his peers are shorter than Fernando is 21.19%.
The correct option is (d).
Answer:
(2,4)
Step-by-step explanation:
1. Add the 2 x-values together, then divide. The resulting number is the x-value of the midpoint. -4+8=4 and 4/2=2, so the x-value is 2
2. Do the above steps (add & divide) for the two y-values. 6+2=8 and 8/2=4, so the y-value is 4
3. put the two values together in a coordinate pair & you have your midpoint! so if x=2 and y=4, then the midpoint is (2,4)
hope this helps :)
To determine how long it will take to fill the empty tank, you will first find the capacity of the tank (the volume) and then divide this into groups of 750 cm^3. Every group will be one minute.
V =lwh
20 x 20 x 15
V = 6000 cm^3
6000 cm^3/750 cm^3 = 8
It will take 8 minutes to fill the empty tank.
1/2 * 1/2 = 1/4
Kailie has 1/4 of a chance of rolling 2 even numbers both times. Hopefully this helped you.
