Answer:
Nearest ten-350
Nearest hundred-300
Step-by-step explanation:
#When rounding to the nearest ten, we look at the ones digits in a number:
- If the ones digit is 0, 1, 2, 3, or 4, you will round down to the previous ten
- If the ones digit is 5, 6, 7, 8, or 9, you will round up to the next ten
Given the number 348, 8 in the ones digit greater than 4 so we round to the next ten:
348 ≈350
#When rounding to the nearest hundred, we look at the tens digits in a number:
- If the ones digit is less than 5 you will round down to the previous hundred
- If the ones digit is greater than 4, you will round up to the next hundred
Given the number 348, 4 in the tens digit less than 5 so we round down to the previous hundred:
348 ≈300
Answer:
81pi
Step-by-step explanation:
pi3^2=9pi
9pi * 9 = 81pi
Area of backyard is not being used 7792 square feet.
Solution:
Length of the backyard = 181 ft
Width of the backyard = 48 ft
Area of the backyard = length × width
= 181 × 48
Area of the backyard = 8688 square feet
Base of the triangle = 16 ft
Height of the triangle = 28 ft
Area of the triangle = 
Area of the triangle = 224 square feet
Length of the rectangle = 32 ft
Width of the rectangle = 21 ft
Area of the rectangular vegetable garden = length × width
= 32 × 21
Area of the rectangular vegetable garden = 672 square feet
Area of backyard not used
= Area of backyard – Area of the triangle + Area of the rectangle
= 8688 – 224 – 672
= 7792 square feet
Area of backyard is not being used 7792 square feet.
The t-test for the two means is appropriate in this situation because women and men are independent samples.
<h3>
What are Independent Samples?</h3>
Independent samples are chosen randomly, ensuring that their results are independent of other observations' values.
The premise that samples are independent underlies many statistical analyses. Others are made to evaluate non-independent sample sets.
The samples of men and women are independent since their results are independent of other observations' values.
The Independent Samples t-Test analyzes the means of two separate groups to see if there is statistical support that the population means values are statistically substantially different.

The graphs are identical and intersect at infinitely many points.
This is because 2(2x+3) is the same as 4x+6
Distribute the outer 2 to each term inside
2 times 2x = 4x
2 times 3 = 6
So 2(2x+3) simplifies to 4x+6
Or you can think of 4x+6 factoring to 2(2x+3)
