Answer:

108 million in scientific notation = 1.08 × 108.

Step-by-step explanation:

If you split the number 108000000 into a coefficient and a power of 10 you do get 108 million in exponential form, but there is an indefinite number of possibilities.

As you probably want 108 million in normalized scientific notation, the coefficient or significand of 108m in scientific notation must be in the interval [1,10[.

As there are many ways to express 108 million in scientific notation, in this post we mean 108 million in normalized scientific notation, unless stated otherwise. Therefore: 108 million in scientific notation = 1.08 × 108.

brilliants [131]

Answer:

Step-by-step explanation:

a) H0: μ = 10

Ha: μ ≠ 10

This is a two tailed test

n = 13

Since α = 0.01, the critical value is determined from the t distribution table. Recall that this is a two tailed test. Therefore, we would find the critical value corresponding to 1 - α/2 and reject the null hypothesis if the absolute value of the test statistic is greater than the value of t 1 - α/2 from the table.

1 - α/2 = 1 - 0.01/2 = 1 - 0.005 = 0.995

The critical value is 3.012

The rejection region is area > 3.012

b) Ha: μ > 10

This is a right tailed test

n = 23

α = 0.1

We would reject the null hypothesis if the test statistic is greater than the table value of 1 - α

1 - α = 1 - 0.1 = 0.9

The critical value is 1.319

The rejection region is area > 1.319

c) Ha: μ > 10

This is a right tailed test

n = 99

α = 0.05

We would reject the null hypothesis if the test statistic is greater than the table value of 1 - α

1 - α = 1 - 0.05 = 0.95

The critical value is 1.66

The rejection region is area > 1.66

d) Ha: μ < 10

This is a left tailed test

n = 11

α = 0.1

We would reject the null hypothesis if the test statistic is lesser than the table value of 1 - α

1 - α = 1 - 0.1 = 0.9

The critical value is 1.363

The rejection region is area < 1.363

e) H0: μ = 10

Ha: μ ≠ 10

This is a two tailed test

n = 20

Since α = 0.05, we would find the critical value corresponding to 1 - α/2 and reject the null hypothesis if the absolute value of the test statistic is greater than the value of t 1 - α/2 from the table.

1 - α/2 = 1 - 0.05/2 = 1 - 0.025 = 0.975

The critical value is 2.086

The rejection region is area > 2.086

f) Ha: μ < 10

This is a left tailed test

n = 77

α = 0.01

We would reject the null hypothesis if the test statistic is lesser than the table value of 1 - α

1 - α = 1 - 0.01 = 0.99

The critical value is 2.376

The rejection region is area < 2.376

What is the greatest common factor of 96x^2 and 88x
nevsk [136]

Answer:

GCF = 8x

Step-by-step explanation:

Find the GCF of the constants:

96 and 88 are both divisible by 8 which is the GCF of the constants.

The GCF of the variables is x, as you cannot divide x by anything more than x.

The total GCF is 8x.

Answer:

1:D

2:A

3:C

4:E

5:B

Step-by-step explanation:

A negative exponent will be when you move the decimal point to the left. A positive exponent will be moving the decimal point to the right.

The number of the exponent is how many times you will move the decimal point.
