PLEASE HELPPPPP ME PLEASE I DONT KNOW WHAT TO DO ☹️#8
Hi there!

We can use the Pythagorean Theorem to solve:
Use the formula a² + b² = c² where:
"a" and "b" are the legs
"c" = Hypotenuse
The diagonal side, or the length of the ladder is 10cm, and one of the legs of the triangle is 8cm, therefore:
(8)² + b² = 10²
64 + b² = 100
Subtract 64 from both sides:
b² = 36
Take the square root of both sides:
√b² = √36
b = 6 cm. This is the distance of the wall from the foot of the letter.
Edit: Typo.
Answer:
6 miles
Step-by-step explanation:
If the city bus goes 18 miles in 30 minutes, divide 18 by 3 to get how far it travels in 10 minutes.
18 ÷ 3 = 6.
The city bus travels 6 miles in 10 minutes.
Answer:
The x intercept is at (1,0)
A suitable probability calculator will tell you that probabilty is about 25.9%.

The normalcdf function on this calculator gives an area between a lower and upper limit. If the upper limit is more than about 8 standard deviations above the mean, the 10th decimal place is unaffected. Since the standard deviation here is about 5, we need to have an upper limit that is about 40 above the mean of about 30. We have chosen 80 as a nice round number and to give a little more margin.
