Answer:
1385mm squared
Step-by-step explanation:
Area of Circle formula: A = pi r^2
You need to divide 42mm by 2 since that is a diameter.
*Half of the diameter is the radius*
42/2 = 21
Now, do 3.14 multiplied by 21 to the power of 2.
Formula: A = 3.14 x 21^2
Do 21^2 first.
That shall be 441
Now do 3.14 x 441
1,384.74mm - That is your exact answer.
The directions tell you to round it to the nearest whole number
THAT IS 1385mm squared

Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in the following box plots:
two box plots shown. The top one is labeled Males. Minimum at 1, Q1 at 3, median at 10.5, Q3 at 14, maximum at 21. The bottom box plot is labeled Females. Minimum at 0, Q1 at 15, median at 18, Q3 at 21, no maximum shown
Identify any values of data that might affect the statistical measures of spread and center.
The females worked more than the males, and the female Q3 equals the top of the range.
The spread and center are skewed due to the fourth quartile missing with the females.
There is a significant outlier at the low end for the females.
The males have a high outlier, and the females have a low outlier

Over the years, separate teams of scientists have been tracking and studying different bird species in Africa. They want to know if certain bird populations have been increasing or decreasing over time. For 8 years, one team of scientists has tracked the African Fish Eagle. When their research began, there were 32,800 African Fish Eagles in Africa. Today, there are 43,952 African Fish Eagles living in Africa. Meanwhile, another team of scientists have been tracking the Tawny Eagle. Over the last 8 years, the population of Tawny eagles went from 7,900 to 10,981. Which eagle species saw a larger percent increase to their population over the last 8 years?
Answers
Answer:
Tawny Eagle
Step-by-step explanation:
Percent Change Formula
[tex]\sf percent\:change=\dfrac{final\:value-initial\:value}{initial\:value} \times 100[/tex]
African Fish Eagle
Given:
Initial population = 32,800Final population = 43,952[tex]\implies \sf percent\:change=\dfrac{43952-32800}{32800} \times 100=34 \%[/tex]
Tawny Eagle
Given:
Initial population = 7,900Final population = 10,981[tex]\implies \sf percent\:change=\dfrac{10981-7900}{7900} \times 100=39 \%[/tex]
Solution
Therefore, the Tawny Eagle species saw a larger percent increase to their population over the last 8 years.

Based on the information given:
⇒ there are 12 people --> Emily, Delvenal, 10 other friends
⇒ the pan of brownies needs to be evenly split among them.
Consider the possibilities:
One option: cut the pan of brownies into the 12 pieces⇒ so that everyone gets one piece of brownie
Second Option: cut the pan of brownies into 24 pieces⇒ so that everyone can gets two piece of brownie
In other words, you can cut a number of pieces that must be divisible by 12 in other to split equally within the group.

A.
36° F
B.
68° F
C.
48° F
D.
52° F
Answers
Answer:
B.
Step-by-step explanation:
C= 20 degrees Celsius
20 x 9/5 = 180/5
180 divided by 5 = 36 degrees celsius
Then you do 36 degrees celsius + 32 and you get 68.
So therefore 20 degrees celsius is eqivalent to 68 degrees Fahrenheit.

Answer:
Decrease Median and Mean
Step-by-step explanation:
The mean and median will both be decreased because you are removing the largest number value from the number line, logically it must decrease.
Answer:
Before Suzanne left:
Mean = 53,333
Median = 45,000
After Suzanne left:
Mean = $44,000
Median = $44,000
Step-by-step explanation:
Since the larger number was taken away the mean and median decreased after she left. The 100,000 is an outlier which basically holds up the mean and median salary.
