Answer:
yes
Step-by-step explanation:
This problem has some information which does not pertain to the answer. The sample size of 60 is not important to the answer. (Sample size is a concern when it comes to deciding if the survey results are valid!)
75% of the sample says they're going to college, so assuming that the same proportion of students in the entire school is going to college, you need to find 75% of 900.
900 x .75 = 675, the same as the counselor's determination.
Answer:
Explanations:
To convert angles from degrees to radians, multiply the angle by π/180
For angle 126°, the equivalent measurement in radian is:
Reduce to the lowest term by dividing the numerator and denominator by 18:
Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.
Answer:
<h2>y = 2</h2>
Step-by-step explanation:
Put x = -13 to the equation -3x + 9y = 57
(-3)(-13) + 9y = 57
39 + 9y = 57 <em>subtract 39 from both sides</em>
9y = 18 <em>divide both sides by 9</em>
y = 2
# 4 is a function because all the x numbers are only used once
