Answer:
Option (A)
Step-by-step explanation:
One side of the given triangle is a diameter of the semicircle given.
Measure of the diameter = 10 units
Total area of the semicircle =
=
= 39.27 square units
Area of the right triangle =
=
= 24 square units
Area of the shaded region = Area of the semicircle - Area of the right triangle
= 39.27 - 24
= 15.27 square units
≈ 15 square units
Therefore, option (A) will be the answer.
Answer:
Option (b) 36.7
Step-by-step explanation:
Data provided in the question:
Treatment 1 Treatment 2 Treatment 3 Treatment 4
Sample Size 50 18 10 17
Sample Mean 32 36 42 48
Now,
The overall mean is calculated as
=
Here, Xi = Sample mean
n = sample sizes
Thus,
Overall mean
= [ (50 × 32) + (18 × 36) + (10 × 42) + (17 × 48) ] ÷ [ 50 + 18 + 10 + 17 ]
= [ 1600 + 648 + 420 + 816 ] ÷ 95
= 36.67 ≈ 36.7
hence,
Option (b) 36.7
Answer:
17
Step-by-step explanation:
Assuming the field is a rectangle, the perimeter is found through the equation:
Since we know the perimeter and width, we can substitute and solve for the length.
Using the length and width, we can find the area.
The area is 2976 squared meters. We divide by the area a bag of canola seed can cover and round up if necessary to find the total number of bags.
Because we need a whole bag in order to cover for the decimal area, we round up to 17 bags.
They both have the same fractions and 64 ÷ 8 = 8 and 2/3 ÷ 2/3 = 1/10
so the answer is 8
so the answer is 8
