Answer:
68
Step-by-step explanation:
We let the random variable X denote the height of students of the college. Therefore, X is normally distributed with a mean of 175 cm and a standard deviation of 5 centimeters.
We are required to determine the percent of students who are between 170 centimeters and 180 centimeters in height.
This can be expressed as;
P(170<X<180)
This can be evaluated in Stat-Crunch using the following steps;
In stat crunch, click Stat then Calculators and select Normal
In the pop-up window that appears click Between
Input the value of the mean as 175 and that of the standard deviation as 5
Then input the values 170 and 180
click compute
Stat-Crunch returns a probability of approximately 68%
Answer:
sinθ = 
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
= (24)² + 7²
Hypotenuse = √625 = 25
By applying sine rule in the given triangle,
sinθ = 
Since, measure of opposite side = 24
Measure of hypotenuse = 25
Therefore, sinθ = will be the answer.
Answer:
Isolate "x" on one side of the algebraic equation by dividing the number that appears on the same side of the equation as part of "x." For example, in the equation "12x = 24", rewrite the equation as "x = 24 / 12" and solve for "x." The solution is "x = 2."

Answer:
v=1460.26536188 units^3
Step-by-step explanation:
Volume for a cylinder is:
V=πr^2h
Substitute 6 in for r and 13 in for h
V=π(6^2)(13)
V=π(36)(13)
V=π468
v=1460.26536188 units^3
Hope this helps! :)
