Answer:
Step-by-step explanation:
The way to approach this that makes the most sense to a student would be to find out how far from the house the ladder currently is, then add 3 feet to that and do the problem all over again. This is right triangle stuff...Pythagorean's Theorem in particular. The ladder is the hypotenuse, 52 feet long. The height of the rectangle is the distance the ladder is up the side o the house, 48 feet. We plug those into Pythagorean's Theorem and solve for the distance the ladder is from the house:
and
and
so
x = 20. Now if we add the 3 feet that the ladder was pulled away from house, the distance from the base of the ladder to the house is 23 feet, the ladder is still 52 feet long, but what's different is the height of the ladder up the side of the house, our new x:
and
and
so
x = 46.6 feet
In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
sunny snowy
Male: 17 11
Female: 15 16
Add the rows up.
sunny snowy total
Male: 17 11 28
Female: 15 16 31
Then divide the number the by the total:
sunny snowy total
Male: 17/28 11/28 28
Female: 15/31 16/31 31
Yours says to round to the 1000th place, so it ends up like:
sunny snowy
Male: .607 .393
Female: .484 .515
Hope that helps!!

Complete question:
what is the answer to 22 +10x = 0
Answer:
the value of x is -2.2
Step-by-step explanation:
Given;
22 +10x = 0
collect like terms
10x = 0 - 22
10x = -22
divide both sides by 10
Therefore, the value of x is -2.2
