The GCF of 40 16 and 24 is 8
<h3>How to determine the GCF of 40 16 and 24?</h3>
The numbers are given as:
40 16 and 24
Start by listing out the factors of the numbers:
This is done as follows:
- The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
- The factors of 16 are: 1, 2, 4, 8, 16
- The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
Then the greatest common factor in the above list is 8.
Hence, the GCF of 40 16 and 24 is 8

Answer: c
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle. That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.
The bottom triangle has 3 angles that sum to 180 degrees, The other angle not marked is also y since it is an isosceles triangle.
40 + y +y = 180
Subtract 40 from each side and combine like terms
40-40 +2y = 180-40
2y = 140
Divide by 2
2y/2 = 140/2
y = 70
Even numbers end with 2,4,6,8, or 0. Thus, 28 is the even number.
Answer:
Dependent sample: The same textbook are being compared.
Step-by-step explanation:
We are given the following in the question:
A student wants to compare textbook prices for two online bookstores.
Sample 1 from bookstore A:
$115, $43, $99, $80, $119
Sample 2 from bookstore B:
$110, $40, $99, $69, $109
Dependent and independent sample:
- Dependent samples are paired observations for same set of items.
- Independent samples are observations made on two different sets of items.
- If the values in one sample affect the observations in the other sample, then the samples are dependent.
- If the values in one sample have no effect about those of the other sample, then the samples are independent.
Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.
