If there are 21 values in a data set in order from smallest to largest, what is the first quartile of the data set?A. The mean of the 6th and 7th values
B. The mean of the 5th and 6th values
C. The mean of the 3rd and 4th values
D. The mean of the 4th and 5th values
Answers
Answer with explanation:
Total Number of Variate in the Data set = 21
Since number of Variate is odd, median is given by the formula:
= Mid value between lowest Variate and Median value.
→→Mid value of first 11 Terms is given by
Most Appropriate Option:⇒
Option A: →The mean of the 6th and 7th values

The function t(x) = 3x + 1 determines how many cans of green beans a food truck needs to stock on board, where x is the number of shifts the crew is going to work in the truck. The crew uses c(t(x)) to find the amount of money to spend on green beans. The function c(x) = x + 4. Solve for how much money must be spent when the crew is going to work 2 shifts.

y=mx+b, m=slope b=y inercept
find slope
slope=(y1-y2)/(x1-x2)=(2-(-4))/(-1-5)=(6)/(-6)=-1
slope is -1
y=-1x+b
input one of the points and solve for b
2=-(-1)+b
2=1+b
subtract 1 form both sides
1=b

1) x = 180° - 45° - 56° 4) a = 180° - 63° - 90°
x = 79° a = 27°
2) z = 180° - 44° - 90° 5) a = 180° - 135°
z = 46° a = 45°
3) x = 180° - 47° - 45° 6) x = 180° - 52° - 90°
x = 88° x = 38°
y = 180° - 133°
y = 47°

Answer:
a matrix with 1's in the main diagonal and zeros everywhere. The identity matrix of order 2×2 is: [1 0 0 1].
Final answer:
The 2x2 identity matrix is a square matrix with 1s on the main diagonal and 0s elsewhere. It serves as the multiplicative identity in matrix multiplication, leaving the original matrix unchanged when multiplied.
Explanation:
In mathematics, the 2x2 identity matrix, denoted by the symbol I or Id, is a square matrix containing elements that make it act as the multiplicative identity in matrix multiplication. Specifically, a 2x2 identity matrix is written as:
I = [1, 0; 0, 1]
Here, the numbers 1 are positioned on the main diagonal from the top-left to bottom-right (also termed as principal diagonal). The other elements, outside the main diagonal, are 0. This particular configuration results in special properties such as, when any matrix is multiplied by the identity matrix, the original matrix is unchanged. So, if we have a 2x2 matrix A, then multiplying by the identity gives AI = IA = A.
