Step-by-step explanation:
1. first multiply -1 times all elements of matrix A
2. then multiply 1/3 by all elements of matrix B
3. then add each corresponding entries to get the result.
from step 1. matrix A will be
-4 -2. -1. -3
-2. 0. 1. -3
step 2. matrix B will be
3. -1. -2. -4
3. -10. 10. -1
add each corresponding elements to get
-1. -3. -3. -7
1. -10 11. -4

Step-by-step explanation:
Tito wants to buy some peanut butter to donate as much as possible.
There some brands are given with their price.
we will calculate the price of per ounce peanut butter of each brand.
A. Nutty : 12 ounces for $2.19
cost per ounce =
= $0.1825 ≈ $0.18 per ounce
B. Grandma's : 18 ounces for $2.79
cost per ounce =
= $0.155 ≈ $0.16 per ounce
C. Bee's : 0.28 ounces for $4.69
cost per ounce =
= $16.75 per ounce
D. Save-A-Lot : 40 ounces for $6.60
cost per ounce =
= $0.165 ≈ $0.17 per ounce
The lowest price is $0.16 per ounce. So he should buy Grandma's peanut butter.
The first box plot shows the value of Q1 = 32 and Q3 = 37. Hence the Interquartile range = 37-32 = 5
The second box plot shows the value of Q1 = 29 and Q3 = 36, Hence the interquartile range = 36-29 = 7
Team B has bigger interquartile range than team A and it shows that the data spreads more than Team A's
It also shows that Team A's scores are more consistent
Pentagon is a five-sided polygon.The sum of interior angles of a pentagon is 540 degrees. A regular pentagon can be subdivided into 5 triangles. The triangles formed are equilateral triangle, when you get the area of each triangle and multiply it by 5 you will get the area of the polygon.The answer is True
