beks73 [17]

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 = <u><em>mean number of clicks per day.</em></u>

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.

MATH
Cerrena [4.2K]

Answer:

1. x = 86

2. x = 31

3. x = 64

4. x = 29

Step-by-step explanation:

1. 2x + 8 = 180

-8 -8

2x = 180 (divide both sides by 2 to get x by itself)

2. 3x - 3 = 90

+ 3 +3

3x = 93 (divide both sides by 3 to get x by itself. you divide because 3x is multiplying and you have to do the reverse operation)

3. 2x -5 + x - 7 = 180 (you combine like-terms)

3x -12 = 180

+12 +12

3x = 192 (you divide by 3 on both sides)

4. x + 1 + x + 4 + x - 2 = 90 (combine like-terms)

3x + 3 = 90

-3 -3

3x = 87 (divide both sides by 3)

Can some help me pls<br> And fact
Anon25 [30]

Answer:

80

Step-by-step explanation:

The three angles of a triangle add to 180 degrees.  One angle is 10, the second is a right angle( which is 90 degrees).  Let the third angle be x

10 +90 +x = 180

Combine like terms

100 +x =180

Subtract 100 from each side

100-100 +x= 180-100

x = 80
