Answer:
53 52 72 61 68 58 47 47 (arrange it)
47 47 52 53 58 61 68 71 (done!)
Mode: 47 (appear twice)
Median: (53+58)/2 = 55.5
Mean = 47+47+52+53+58+61+68+71/ 8
=457/8
=57.12
Answer:
The GCF of 36 and 90 is 18
Answer:
x=2
Step-by-step explanation:
8 + x = 4x +2
Subtract 4x from both sides:
8 + x - 4x = 4x + 2 - 4x
Group like terms:
x - 4x + 8 = 4x + 2 -4x
Simplify the arithmetic:
-3x + 8 = 4x + 2 -4x
Group like terms:
-3 + 8 = 4x - 4x + 2
Simplify the arithmetic:
-3x + 8 = 2
Answer:
{13,14}
Step-by-step explanation:
Let
x ----> number of hours per week of tutoring
y ----> number of hours per week of landscaping
we know that
She can work no more than 17 hours
so
-----> inequality A
She must earn at lest $240
The term " at least" means, "greater than or equal to"
----> inequality B
If Autumn worked 3 hours landscaping
then

substitute in the inequality A and in the inequality B
<em>Inequality A</em>

Inequality B

The solution of the system is the interval {12.75,14]
All possible values for the number of whole hours tutoring that she must work to meet her requirements are
{13,14}
Answer: 57.1
Step-by-step explanation: To be complementary the angles have to add up to make a sum of 90.
90 - 32.9 = 57.1
The angles are 32.9 and 57.1.
