Answer:
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
Step-by-step explanation:
Martin has 2 5/8 pounds of ground beef.
2 5/8 = 21/8 pounds = 2.625 pounds
Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
The standard deviation is 1.43 below the mean
<h3>How to determine the number of standard deviation?</h3>
The given parameters are:
Mean = 98.249
Standard deviation = 0.733
x = 97.2
To calculate the number of standard deviation below the mean, we use

So, we have:

Evaluate the like terms

Divide both sides by -0.733
n =1.43
Hence, the standard deviation is 1.43 below the mean

Answer:
The pairs of supplementary angles are
∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .
Step-by-step explanation:
Definition of supplementary angles
When sum of two angles are 180° they are called supplementary angles .
As figure given in the question
∠3 = 90°
Thus
∠3 + ∠6 = 180 °
(By using Linear pair property)
∠4 + ∠5 = 180 °
(By using Linear pair property)
∠3 + ∠4 = 180 °
(By using Linear pair property)
Therefore the pairs of supplementary angles are
∠4 and ∠3 , ∠3 and ∠6 , ∠4 and ∠5 .
Answer:
7 marbles
Step-by-step explanation:
Let the number of marbles he had be x
ie. X + 2X =21
3X=21
X=21/3=7
