Answer:
268.67 pages per hour
She read the whole book is 1.79 hours.
Step-by-step explanation:
Shryia read for 1.5 hours 403 pages of a 481 page book. Her rate is the number of pages she read divided by the time it took her.
403 / 1.5 = 268.67 pages per 1 hour.
To find how long it took her to read the whole book, divide 481 by her rate.
481 / 268.67 = 1.79
She read the whole book is 1.79 hours.
Answer: being similar means they are in the same ratio. so x = 12
Step-by-step explanation:
first put it into a ratio, 4/x =2/6 and answer it like an equation.
4/x=2/6 (cross multiply)
24=2x
x=12
Answer:
Part 1) For a octagon, the measure of one interior angle is 135 degrees and the measure of one exterior angle is 45 degrees
Part 2) For a icosagon, the measure of one interior angle is 162 degrees and the measure of one exterior angle is 18 degrees
Step-by-step explanation:
Part 1) we have a 8-gon
we know that
A 8-gon or octagon, Is an eight-sided polygon
step 1
The measure of one interior angle in a octagon is equal to
where
n is the number of sides of the regular polygon
For n=8
step 2
To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides
so
Part 2) we have a 20-gon
we know that
A 20-gon or icosagon, Is a twenty-sided polygon
step 1
The measure of one interior angle in a icosagon is equal to
where
n is the number of sides of the regular polygon
For n=20
step 2
To find the value of a given exterior angle of a regular polygon, simply divide 360 by the number of sides
so
Stronger evidence against the null hypothesis is indicated by: smaller p-values.
<h3>What is null hypothesis?</h3>
A statistical conjecture known as a null hypothesis asserts that certain features of a population or data-generating process are not different from one another.
A mechanism to reject the null hypothesis with a predetermined level of confidence is provided by hypothesis testing.
The alternative hypothesis is supported if the null hypothesis can be rejected.
The foundation of the scientific falsification principle is null hypothesis testing. The null hypothesis presupposes that any variation in the selected characteristics you observe in a set of data is the result of chance.
