Answer:

Null Hypothesis, $H_0$ : $\mu$ = 200 clicks a day

Alternate Hypothesis, $H_A$ : $\mu\neq$ 200 clicks a day

Step-by-step explanation:

We are given that a website developer wished to analyze the clicks per day on their newly updated website.

The website developer wants to know if the number of clicks per day is different than 200 clicks a day, on average.

Let $\mu$ = mean number of clicks per day.

So, Null Hypothesis, $H_0$ : $\mu$ = 200 clicks a day

Alternate Hypothesis, $H_A$ : $\mu\neq$ 200 clicks a day

Here, the null hypothesis states that the mean number of clicks per day is 200 clicks a day.

On the other hand, the alternate hypothesis states that the mean number of clicks per day is different than 200 clicks a day.

Hence, this is the correct null and alternative hypotheses.

Answer:

$\boxed{7-4=11\:or\:6+3=9}$

Step-by-step explanation:

Let $p$ and $q$ be two propositional statements.

The disjunction $p\vee q$ is true if either $p$ or $q$ is true or both are true.

In the given options;

The statement;

$7-4=11$ is false

But;

$6+3=9$ is true.

Hence,

$7-4=11\:\vee \:6+3=9$ is true

The correct answer is D

Answer:

A=35, B=55, and C=25

Step-by-step explanation:

Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.

if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B

Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
