Answer:
a = 15/2
Step-by-step explanation:
3a−15=4a−3a
Combine like terms
3a - 15 = a
Subtract 3a from each side
3a-3a−15=a−3a
-15 = -2a
Divide each side by -2
-15/-2 = -2a/-2
15/2 =a
The circumference of a circle is equal to pi * diameter
So 10 miles = 0.75 * pi * d
10/(0.75*pi) = d
d = <span>4.244 miles</span>
Answer:
it would be a 3/15 or 1/5 chance
Step-by-step explanation:
Answer:
Here we can go for trial and error,
Taking x=6
So equation will be 6*6-18 which gives 18
and is not equal to 54
So it's, not 6
Trying 12
6*12-18
Which is 54 and so correct answer is x=12
Answer: the answer is 2.67
Step-by-step explanation: Noah and Gabriel have taken 6 quizzes in English class so far. There are no outliers in their quiz scores. Find the measure of variability for Noah’s scores.
Noah’s scores: 84, 85, 85, 86, 90, 92
Mean: 87
Range: 92 – 84 = 8
Gabriel’s scores: 82, 85, 86, 86, 90, 94
Mean: 87.17
Range: 94 – 82 = 12
MAD: 3.22
What is Noah’s mean absolute deviation?
2.67
