Multiply then divide by 2
Answer: 0.42
Step-by-step explanation:
Given: Mean : 
Standard deviation : 
Sample size : 
The formula to calculate z score is given by :-
For X=960
The p-value =
Hence, the probability that a single randomly selected value is at least 960 dollars = 0.42
Answer:
13.4112
Step-by-step explanation:
To convert a mile per hour measurement to a meter per second measurement, multiply the speed by the conversion ratio. One mile per hour is equal to 0.44704 meters per second, so use this simple formula to convert:
meters per second = miles per hour × 0.44704
Answer:
a) Set up triangles where the hypotenuse is 16ft (the ladder) and one of the two edges are 1, 2, 3, 4, 5ft (the base of the ladder). Use a^2 + b^2 = c^2 where a is the base length, c is the hypotenuse and b is the value you are trying to find.
Ex w/ 1ft base:
1^2 + b^2 = 16^2
1 + b^2 = 256
b^2 = 255
b = 15.97ft.
b) Simply take your answers from part a) and add 5.5ft (the height of the girl) to them.
Ex w/ 1ft base:
15.97ft + 5.5ft = 21.47ft
c) Using logic here think about it. Let's take the 1ft base as the example. Marissa standing on top of the ladder is 21.47ft. That's clearly not high enough to reach the cat . . . but what happens if Marissa reaches upwards. As long as her arms can reach roughly 1.53ft above her head she should be able to reach it.
