Answer:
hmm i have no idea can u send a clear pic of question?
Answer:
D. (3,-2)
Step-by-step explanation:
When we rotate a point 180 degrees about the origin, the rule is:
(x,y) -> (-x,-y)
So let's use this rule with our point.
(-3,2) -> (3,-2)
The answer is D (3,-2)
At 0.01 significance level the hypothesis is rejected.
Null Hypothesis (H₀): The sample data occurs purely from chance.
Alternative Hypothesis (H₁): The sample data is influenced by some non-random cause.
If the p-value of the hypothesis test is less than some significance level (e.g. α = .01), then we can reject the null hypothesis and conclude that we have sufficient evidence to say that the alternative hypothesis is true.
Given that,
x = 28
s = 2.9
μ = 31
n = 8
α = 0.01
Then, the Null Hypothesis : H₀ = 31
The Alternate Hypothesis : H₁ < 31
The average number of cigeratte smoker per day is less than 31.
Test Statistics:
t = x -μ / s√n
= 28 - 31/ 2.9√8
= -3/ 8.41
= -0.356
Since the p-value of 0.0046 is less than the significance level of 0.01, the auditor rejects the null hypothesis.

Say you buy a brand new candle from the store, and pretend like its 3 inches tall.
The moment you light it, that candle will still be 3 inches, but as time goes on and on, the wax of the candle is gradually melting and melting. So in other words the wax is getting less and less from its starting measurement of 3 inches. Soon it will be 2 inches then 1 inch and after that, none at all. So by now you should be thinking it is a negative graph because the wax is getting less and less.
You may be wondering if the graph is curved, the answer is no because very soon after you lit your imaginary candle, the fire stabilized and formed into a constant shape that emits constant heat (assuming you don't apply anything extra.)
So we conclude that it is a negative linear graph.
Answer:
1/2
Step-by-step explanation:
If y is the √3/2 on the unit circle, x must be either 1/2 or -1/2.
