disa [49]3 years ago
5 0

Answer:

A= 57 sq units

Step-by-step explanation:

To calculate the are area of a triangle we use the Herons formula:

A=√s(s-a)(s-b)(s-c) where a, b and c are the sides of the triangle.

s=(a+b+c)/2

s=(10+13+12)/2

=17.5

A=√[17.5(17.5-10)(17.5-13)(17.5-12)]

A= 57 sq units

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.
