Complete Question:
The smallest hummingbird is the Bee hummingbird. It has a mass of about 1 1/2 grams. The mass of a larger type of hummingbird is about 5 times the mass of the Bee hummingbird.
What is the mass of the larger humming bird?
Answer:
7 1/2 grams
Step-by-step explanation:
The mass of Bee humming bird is given in the question as = 1 1/2 grams
Mass of the larger humming bird = 5 times the mass of Bee humming bird
The mass of the larger humming bird is calculated as:
5 × 1 1/2 grams = 5 × 3/2 grams
= 15/2 grams = 7 1/2 grams
Therefore, the mass of the larger humming bird is 7 1/2 grams
The standard deviation of the mileage for the sample of convertibles is 1.98977 miles.
<h3>What is standard deviation? </h3>
Standard deviation is used to determine how the values in a group differs from the mean of the values in the group. It is a measure of variation.
<h3>What is the standard deviation of the mileage? </h3>
In order to determine the standard deviation, take the following steps:
- Determine the mean of the observation:
(25 + 25 + 24 + 21 + 21 + 21 + 20) / 7 =22.43
- Determine the difference between each value and the mean and then square the result:
(25 - 22.43)² = 6.6049
(25 - 22.43)² = 6.6049
(24 - 22.43)² = 2.4649
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(21 - 22.43)² = 2.0449
(20 - 22.43)² = 5.9049
Sum of squared difference = 27.7143
- Determine the mean of the square differences and then find the square root of the mean:
√27.7143 / 7 = 1.98977

Answer:
It will take 4.71 hours to travel a distance of 221.43 miles
Step-by-step explanation:
Given
Distance covered in time 7.99 hours is 375.32 miles.
Now we know that speed is equal to distance per unit time.
Therefore,
Which is the constant speed, hence now time taken for a distance of 221.43 miles will be
Therefore, the time taken to cover 221.43 miles is 4.71 hours.
Answer11
Step-by-step explanation:
30.95-6.75 is 24.20 now 24.20 divided by 2.20 is 11
