Answer:
18.4 feet
Step-by-step explanation:
-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.
-let the ladder be C, the wall be a, the base to the bottom be b.
-substitude into the equation, which will leave us with:
C^2 = 17^2 + 7^2
C^2 = 289 + 49
C^2 = 338
C = square root of 338, which is 18.4 feet!
#1: The whole value of data is 21.
There are 21 data values on the dot plot.
#2: The number of data values is 14.
#3: The unit is: 21 ÷ 14.
And it is 1.5.
#4: A statistical question can be answered by collecting data and where there will be variability in that data.
For example, how many students enjoy playing game?
kilograms of yellow potatoes bought is 8330 kg
<em><u>Solution:</u></em>
Given that James buys 245 kilograms of red potatoes
He buys yellow potatoes that weigh 34 as much as the red potatoes
To find: kilograms of yellow potatoes bought by James
Let "y" be the kilograms of yellow potatoes bought
Let "r" be the kilograms of red potatoes bought
kilograms of red potatoes bought = 245 kilograms
r = 245 kilograms
From given information,
Yellow potatoes weigh 34 as much as the red potatoes
here "as much as" means product or multiplication
Kilograms of yellow potatoes bought = 34 x kilograms of red potatoes bought

Thus kilograms of yellow potatoes bought is 8330 kg
The answer cannot be expressed in mixed number since whole numbers has no fractional part
