y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
Answer:
Angle 1: 52 degrees
Angle 2: 128 degrees
Step-by-step explanation:
Angle 1 = x
Angle 2 = 2x + 24
Supplementary angles are two angles that add up to 180 degrees.
x + 2x + 24 = 180
3x + 24 = 180
3x = 180 -24
3x = 156
x = 52
Check:
Angle 1: x = 52
Angle 2: 2x + 24
2(52) + 24
104 + 24 = 128
128 + 52 = 180
Answer:
x= 8

<h2>
Answer with explanation:</h2>
Given : Sample size 
Sample mean : 
Sample standard deviation : 
Let 
be the population mean of "like" ratings of male dates made by the female dates.
As per question ,
Null hypothesis : 
Alternative hypothesis : 
, It means the test is a one-tailed t-test. ( we use t-test when population standard deviation is unknown.)
Test statistic:
For 0.05 significance and df =188 (df=n-1) p-value = .001582. [By t-table]
Since .001582< 0.05
Decision: p-value < significance level , that means there is statistical significance, so we reject the null hypothesis.
Conclusion : We support the claim at 5% significance that t the population mean of such ratings is less than 8.00.
Answer:
7.5
Step-by-step explanation:
It is longer than 5, so cross 2.5 and 5 out, 10 is too big, so 7.5 is the correct answer
