Cos 25=0.90631
cos 25=(the end of the slide to the stairway beneath the top of the slide)/( length of the slide)
length of the slide=60/0.90631=66.2
the length of the slide = 66.2 feet

Hi there!
With a normal distribution, we can use the operation 'normalcdf' on a calculator to find the probability that a randomly selected adult has an IQ between 96 and 111.
Here is the format for using the operation:
<h2>normalcdf(LB, UB, μ, σ) </h2>
LB = Lower bound (96)
UB = Upper bound (111)
μ = Mean of normal distribution (100)
σ = Standard deviation of normal distribution (15)
Plug in the given values into the calculator and solve.
About Slope Intercept Form:
- y = mx + b
- m is the slope
- b represents the y-intercept
For the graphing one, since the slope is positive, you have to go up 5 and right 2 because the slope equals <u>rise</u>
run.
5 represents rise & 2 represents run. Then -4 is the starting point, the y-intercept.
Hope this info helps!! :)
