Answer:
2 2/3 ft^2
Step-by-step explanation:
The area of the garden is 10 2/3 ft^2. She used 1/4 of it for the peas.
Multiply 1/4 times the total area to find the amount used for peas.
10 2/3 * 1/4
Change the mixed number to an improper fraction.
(3*10+2)/3 * 1/4
32/3 * 1/4
8/3
Change this back to a mixed number. 3 goes into 8 2 times with 2 left over.
2 2/3 ft^2
This is how much is used for the peas.

Answer:
x = 47
Step-by-step explanation:
86° and 2x° are supplementary angles, which means that added together they should equal 180° (which is a line). Aka
86 + 2x = 180 (Let's solve for x) (subtract both sides by 86 to get x on one side)
2x = 94 (divide both sides by 2 to get x by itself)
x = 47
For number 5 I believe it's 4?
The 95% confidence interval for the population will be 0.312 < SD < 0.885.
<h3>How to calculate the confidence interval?</h3>
From the information given, it should be noted that the values listed below are waiting times of customers at the Jefferson Valley Bank, where customers enter a single waiting line that feeds three teller windows.
The degree of freedom will be:
= 9 - 1 = 8
The number illustrated is 9 and the standard deviation is 0.462.
The 95% confidence interval will be'
= ✓(9 - 1) × 0.462²/17.53) < ✓(9 - 1( × 0.462)²/2.28
= 0.312 < SD < 0.885.
