Answer:

Step-by-step explanation:

2 * 10^7 You are to use a single digit. That's the 2 on the left. Then count what it takes to get the decimal between the 2 and the 3. It's 7

0.000136

Count the number of zeros. Add a minus 1. You want the number to be counted until you get minus 1 which is the number of powers after the 1.

1 * 10^-4

26837 becomes 2 * 10^4. 4 is the number of digits you have before you get to a number between 1 and 10.

0.0302 becomes 3 * 10^-(1 + 1) = 3 * 10^-2

Given the functions f(n) = 11 and g(n) = (3/4)n _ 1, combine them to create a geometric sequence, an, and solve for the 9th term

trapecia [35]

F(n) = 11
g(n) = (3/4)^(n - 1)

To create a geometric sequence. multiply f(x) and g(x)
an = f(x)g(x) = 11(3/4)^(n - 1)

9th term is 11(3/4)(9 - 1) = 11(3/4)^8 = 11(0.100) = 1.101

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 $\mu$ = 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:

So the value of the test statistic is -0.85.

Step-by-step explanation:

We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.

We get that:

$n=1800\\\\p_1=53\%=0.53\\\\p_2=54\%=0.54\\$
