Step-by-step explanation:
We know that,
Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,
The percent of his sales that were less than or equal to 84 inches, is
Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
Answer:
8 maths tests
Step-by-step explanation:
Given data
We are told that in 1/4 hour that is 0.25hour (15 mins) She grades 1 math test
our aim is to find how many maths test she grade in 3 hours (120min)
Hence
in 15 mins she does 1 grading
in 120 mins she does x
cross multiply
15x= 120
divide both sides by 15
x= 120/15
x= 8 maths test
Hence in 2 hours, she can grade 8 maths tests

Answer:
Answer:
m=−7
Step-by-step explanation:
Let's solve your equation step-by-step.
2981
35
=
−11
7
(8m+
9
5
)
Step 1: Simplify both sides of the equation.
2981
35
=
−11
7
(8m+
9
5
)
2981
35
=(
−11
7
)(8m)+(
−11
7
)(
9
5
)(Distribute)
2981
35
=
−88
7
m+
−99
35
Step 2: Flip the equation.
−88
7
m+
−99
35
=
2981
35
Step 3: Add 99/35 to both sides.
−88
7
m+

35
+
99
35
=
2981
35

99
35
−88
7
m=88
Step 4: Multiply both sides by 7/(-88).
(

−88
)*(88)
m=−7
Answer:
m=−7
Yes
