Answer:
0.3
Step-by-step explanation:
The margin of error is calculated as ...
(standard deviation)/√(sample size) × (z*-score)
where the z*-score is chosen based on the desired confidence level.
Here, you have ...
- standard deviation = 2.7
- √(sample size) = √225 = 15
- z*-score for 90% confidence level = 1.645
Putting these values in the above expression for margin of error gives ...
2.7/15·1.645 = 0.2961 ≈ 0.3
Answer:
The answer is 35 plants.
Step-by-step explanation:
The ratio of tomato plant to that of pepper plant = 2:5
Let x be the number of pepper plants for 14 tomato plants.
Now, according to the question:
2:5 = 14:x
14×5 = 2x
x = 70/2 = 35 plants.
The value of the scale factor k, is 1.5
<h3>
Perimeter</h3>
The perimeter of a shape is the sum of the side lengths of the shape
<h3>
Dimensions </h3>
The dimensions of the triangle MNO are given as:
Calculate the perimeter of the triangle as follows:
Divide 17.25 by 11.5 to calculate the scale factor (k)
Hence, the scale factor is 1.5

49 %
465 + 485 = 950
465/950 = .489
.489 * 100 = 48.9, round up for 49 to get 49%, since it's only focused on people who tested positive, you would only have to compare the people in that column
Answer:
The driveway of the brown house is longer by 5 feet.
Step-by-step explanation:
Given two houses (red and brown) such that:
- The driveway in front of the brown house is 35 feet long.
- The driveway in front of the red house is 7 yards and 9 feet long.
We want to determine which of the houses has a longer driver.
To compare, we must ensure that all units are the same.
Therefore: 7 Yards =3 X 7 feet =21 feet
Driveway of the red house =7 yards and 9 feet long=21+9=30 feet
Therefore:
- The driveway in front of the brown house is 35 feet long.
- The driveway in front of the red house is 30 feet long.
The driveway of the brown house is longer by 5 feet.
