Answer: D
H0: μ=522
H1: μ>522
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
So, for this case;
The null hypothesis is that the mean score equals to 522
H0: μ=522
The alternative hypothesis is that the mean score is greater than 522.
H1: μ>522
A=567 km+900 km
a=1,467 km
b=567 km+169 km
b=736 km
x^2/a^2+y^2/b^2=1
x^2/(1,467)^2+y^2/(736)^2=1

Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
× 
= 
Given
× 
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
Answer:
<h2>Ray.</h2>
Step-by-step explanation:
The statement is the definition of a ray.
In geometry, a ray is half of a line, beacuse it begins at specific point and extends to the infinite, while a line extends from an infinite point to an another infinite point. So, basically, the difference is that a ray starts at a determined point, while a line doesn't.
Therefore, the answer is Ray.
