Answer:
Choose the numbers in the choices that are 50, 70, or any integer in between 50 and 70.
Step-by-step explanation:
Minimum number of pencils: 5 × 10 = 50
Maximum number of pencils: 5 × 14 = 70
The number of pencils ranges from 50 to 70. All integers 50, 70 and in between 50 and 70 are possible.

(b) The result of adding two polynomials is always a polynomial.
Step-by-step explanation:
A set is "closed" under a particular operation if performing that operation on members of the set always results in a member of the set.
Adding two polynomials always results in a polynomial, so we can say "polynomials are closed under addition."

A researcher plans to use a random sample of houses to estimate the mean size (in square feet) of the houses in a large population. The researcher is deciding between a 95% confidence level and a 99% confidence level. Compared with a 95% confidence interval, a 99% confidence interval will be
Considering the margin of error, it is found that the 99% confidence interval will be wider than the 95% confidence interval.
What is the margin of error of a confidence interval?It is given by:
[tex]M = z\frac{s}{\sqrt{n}}[/tex]
In which:
z is the critical value, which increases with a higher confidence level.s is the standard deviation.n is the sample size.From this, we get that the margin of error is direct proportional to the critical value, hence [tex]z_{99}>z_{95}[/tex], which means that the 99% confidence interval will be wider, that is, it will have a larger margin of error, than the 95% confidence interval.

Answer:
3/14
Step-by-step explanation:
Put the number of students that want to be a therapist AND have a fear of height (this would be 3) over the TOTAL amount of students in the sample, in this case it's 14.
so it's 3/14 and it doesn't simplify
you're welcome
Answer:
21%
Step-by-step explanation:
First we need to find the total amount of people that did the personality test. We can do that by adding all the numbers in the table
[tex]4+5+2+3=14\\[/tex]
now, to find the percentage of students that want to be a therapist and a fear of heights, we simply divide the number of students who fit that demographic by the total number of students
[tex]3/14= 0.214[/tex]
therefore, there is a 21% chance of picking a student in that demographic at random
If the length of a rectangle doubles its width. Find the length of the rectangle if the perimeter is 21cm
Answer:
7cm, assuming the question is phrased as noted below.
Step-by-step explanation:
I'll interpret "If the length of a rectangle doubles its width." as "If the length of a rectangle is double its width.
Let L be the width, and L the length
L = 2W
The perimeter of a rectangle is 2L + 2W
We can use L instead of 2W, and that gives us:
21 cm = 2L + L
21 cm = 3L
L = 7 cm
Sean and Glen share a 16 ounce box of cereal. By the end of the week, Sean has eaten 5/8 of the box,glen has eaten 1/4 of the box of cereal. How many ounces are left in the box?
Answer:
2 ounces are left
Step-by-step explanation:
Sean =
[tex] \frac{5}{8} \times 16[/tex]
= 10 ounces
Gien =
[tex] \frac{1}{4} \times 16[/tex]
= 4 ounces
Sean + gien = 10 + 4 = 14 ounces
so therefore the remaining portion
= 16 - 14 = 2 ounces of cereal is left

A store sold 6 3/8 boxes
of Milky Way bars and 7 2/5
boxes of Snickers one
week. In total, how many
boxes of candy bars did
they sell?
Answer:
We add the two fractions:
6 3/8 + 7 2/5 = 13 31/40 boxes of candy bars.
Answer:
Add the two fractions 6 3/8 + 7 2/5 = 13 31/40
Step-by-step explanation:
First multiply the whole numbers by the denominator then add it to the numerator, then find the most common factor (in the denominators) which is 40 (8x5 and 5x8) and multiply the numerator by the same number as the denominator, you will get 255/40 and 296/40 add them then simplify then you will get 13 31/40, thank you.

again, in a geometric sequence all terms are created by multiplying the previous term by a constant factor.
7640 × f = 764
f = 764/7640 = 1/10
a1 = 7640
a2 = a1 × 1/10 = 7640 × 1/10 = 764
a3 = a2 × 1/10 = a1 × 1/10 × 1/10 = 7640 × 1/100 = 76.4
an = 7640 × (1/10)^(n-1)
a6 = 7640 × (1/10)⁵ = 7640 × 1/100000 = 0.0764

1 8. DIG DEEPER! You have 1/8 gallon of melted crayon wax. You pour the wax equally into 8 different molds to make new crayons. What fraction of a cup of melted wax is in each mold? Think: 1 gallon is 16 cups.
Each mold will have 1/32 cup of melted wax.
What is Fraction?A fraction represents a part of a whole.
We know that 1 gallon is equal to 16 cups.
Therefore, 1/8 gallon is equal to:
(1/8) x 16 cups/gallon = 2 cups/8 = 1/4 cup
So we have 1/4 cup of melted crayon wax in total.
If we pour this equally into 8 different molds to make new crayons, each mold will have:
(1/4) / 8 = 1/4 x 1/8 = 1/32 cup
Therefore, each mold will have 1/32 cup of melted wax.

How is ordering factions on a number line similar and different from ordering whole numbers on a number line
Answer:
Fractions and whole numbers ordered on the number line are similar because it tells parts throughout the line, like skip counting using adding or subtraction for example.
What's different from them is because the fractions tell the parts more detailed between the whole numbers, such as 2 3/4 as a fraction on the number line. And 3 as a whole number on the number line.

The perimeter of a reclangle is 44 meters. Its width is 10 meters. What is the length of the rectangle
A.10 meters
B.12 meters
C.14 meters
D.34 meters
Answer: B
The answer would have to be B because when finding the perimeter, you add all the sides up together. If one of the width of the rectangle is 10, then the other would also be 10, which already makes 20. If both lengths are 12, they would add up to be 24. And finally, 20+24=44!
