Yeah 420 i think hope this helps
Answer:
True
Step-by-step explanation:
This set is a function because every input value only has one output value.
Answer: g(x)= -1/2x^2
Step-by-step explanation: since the parabola is opening downwards it would have to be a negative so all we are left with is g(x)=-2x^2 and g(x)-1/2x^2 and if we go in the calculator and type up each equations you would see our answers is g(x)=-1/2x^2
Answer: Hypothesis testing
Step-by-step explanation:
In statistics , Hypothesis testing is a general procedure to check the results of a experiment or a survey to confirm that they have actual and valid results.
Given claim : A recent study claimed that half of all college students "drink to get drunk" at least once in a while. By believing that the true proportion is much lower, the College Alcohol Study interviews an SRS of 14,941 college students about their drinking habits and finds that 7,352 of them occasionally "drink to get drunk".
Here the College Alcohol Study is just testing the results of the survey .
Hence, this is is s a type of Hypothesis testing.
Angle 2 is the same as the given angle of 70 degrees so we can solve for y:
4y-30 = 70
Add 30 to both sides:
4y = 100
Divide both sides by 4:
Y = 25
Angle 1 and angle two are supplementary angles and when added together need to equal 180:
We know angle 2 = 70, so angle 1 must equal 180-70 = 110
2x + 10 = 110
Subtract 10 from both sides:
2x = 100
Divide both sides by 2:
X = 50
The answer is:
X = 50, y = 25
