Which measurement is closest to the area of the circle in square centimeters ? A. 31.4cm² B. 78.5cm² C.62.8² D.50.2cm²
Answer: it’s a
Step-by-step explanation: took the test got it right
The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²
Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²
Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Elle and Layla are collecting data on student use of the school library. They collect data samples from the same population of students. After collecting their data, they each determine the standard deviation for their data sets. Layla's standard deviation is much larger than the standard deviation from Elle's data set.
Answer:
Layla's data set has a greater spread than Elle's data set
Eplanation:
I just got it right on the test I took..
The conclusion is Layla’s data set has more outliers or extreme values than Elle’s data set.
What do you mean by standard deviation?In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
E and L collect data on library use from same students. L’s SD > E’s SD.
Now,
Since Elle and Layla collected data samples from the same population of students, we can assume that they have the same mean for their data sets. Hence, if Layla’s standard deviation is much larger than Elle’s standard deviation, it means that Layla’s data set has more variation or dispersion than Elle’s data set. In other words, Layla’s data set has more outliers or extreme values than Elle’s data set. This could be due to random sampling error or some other factor that influenced Layla’s data collection.
Therefore, by the standard deviation the answer will be Layla’s data set has more outliers or extreme values than Elle’s data set.

Step-by-step explanation:
1)divide by 2
2.) every yellow marble is 1 and there is 5 marbles for each yelllow marble
The ratio of boys to girls in the Grade 6 math class is =
8 : 9.
For every yellow marble, there are five blue marbles.
To find the ratio of a given two quantities how many times one quantity is greater or smaller than the other.
To find the ratio of boys to girls in Grade 6 math class simplify by dividing through with two.
Therefore, 16/18 = 8/ 9, that is 8 boys is to 9 girls.

Answer:

Step-by-step explanation:
First term = a = 4
Common difference = d = second term - first term
= 16 - 4
= 12
Nth term = a + (n -1) *d
= 4 + (n - 1)*12
= 4 + n*12 - 1*12
= 4 + 12n - 12
