Answer:

35,000

Step-by-step explanation:

^4 means 4 zeros

10^4 = 10,000

3.5 times 10,000 =

35,000

The approximate average percent increase per year in student enrollment at the university is = 5%. That is option A.

Initial number of student = 14,000 students

Total number of students over 6 years = 20,000 students

The total additional students for 6 years,

= 20,000- 14,000

= 6,000 students.

Therefore every year additional 1000 students where admitted into the local university.

The average percent increase per year in student enrollment at the university,

= 1000/20000 × 100

= 100000/20000

=5%

Therefore, the approximate average percent increase per year in student enrollment at the university is = 5%.

Answer:

The mode is 9 letters: True

The median is 7.5 letters: True

The mean is 7 letters: False

The graph is skewed right with an outlier of 2: False

Step-by-step explanation:

1) The mode is 9 letters. (True)

The mode is the value that shows up the most. 9 letters shows up the most as the length of a child's last name.

2) The median is 7.5 letters. (True)

The median is one of the middle points of a data set. This can be found by writing out all of the results from least to greatest, and crossing out each number starting from the ends.

2, 6, 6, 7, 7, 7, 8, 8, 9, 9, 9, 9

Once you meet in the middle, you should be left with 7 and 8. In this case, we find the mean of the two numbers, which is 7.5. (In cases where the data set has an odd amount - if there were 13 children instead of 12), you'd just use the middle piece of data.

3) The mean is 7 letters. (False)

The mean is also a middle point of a data set. However, this one is different. The mean can be found by adding up all of the numbers in the data set ([tex]2+6+6+7+7+7+8+8+9+9+9+9[/tex]) and then dividing that number by the amount of numbers are in the data set. Setting this up as an expression would look like: [tex]\frac{2+6+6+7+7+7+8+8+9+9+9+9}{12}[/tex]. By plugging this into a calculator you'd get 7.25 instead of just 7.

4) The graph is skewed right with an outlier of 2.

Although the outlier of 2 part of the statement is correct, the graph is not skewed right; it is skewed left.

Answer:

a. 1/20, 1 out of twenty, or 5%

b. three out of ten, 3/10, 30%

c. 3/20 = 3/20 yes.

Step-by-step explanation:

a. It is a fraction. out of the 20 divisions there is only one 20. so there is 1 out of twenty which as a fraction is 1/20. this is equal to 1 divided by 20 wich eqauls 0.05. You move the decimal to the right twice to get 5%.

b. 6 out of twenty, 6/20. They are both even so it can be simplified.

6  ÷ 2 = 3

20 ÷  2 = 10

It becomes 3/10, 0.3 or 30%

c. I decided that 3, 17, 2, 15, 10, and 9 are the lower right region.

the odds are 6/20 wich we know is 3/10

I only see 20 hits, but out of the 20, 6 are in the lower right region.

the odds from this is 6/20 which we know is 3/10.

We can see that the odds are equal.

By concept of capacity and the assumption of constant flow rate, the amount of ounces of juice in the container after 6 seconds is 20 ounces.

Given that the additional juice is added to the container at constant rate. Hence, the final capacity (C'), in ounces is equal to the sum of the initial capacity (C), in ounces, and the product of the flow rate (q), in ounces per second, and time (t), in seconds.

C' = C + q · t     (1)

If we know that C = 9.5 oz, q = 1.75 oz/s and t = 6 s, then the final capacity of the container is:

C' = 9.5 oz + (1.75 oz/s) · (6 s)

C' = 20 oz

The time Deb finished eating lunch is  12:16 P.M. The correct option is the first option  12:16 P.M.

From the question, we are to determine when Deb finished eating lunch

From the given information,

Deb started doing yard work at 9:52 A.M and she stopped to have lunch after working for 1 hour and 48 minutes.

After working for 1 hour and 48 minutes, the time will be

9:52 A.M + 1 hour 48 minutes = 11:40 A.M

This means she stopped to have lunch at 11:40 A.M.

Then,

It took her 36 minutes to eat lunch

The time Deb finished eating lunch will be

11:40 A.M + 36 minutes = 12:16 P.M.

Answer:

Step-by-step explanation:

The statement that cannot be true is "length RW is a mid segment of the triangle". option D.

The mid segment of a triangle is a line segment that connects the midpoints of two sides of a triangle. More specifically, if a triangle has sides of lengths a, b, and c, then the mid segment connects the midpoints of the two sides of length a and is parallel to the side of length c. The length of the mid segment is half the length of the third side (c/2).

here, we have,

In other words, if a triangle has sides AB, BC, and AC, then the mid segment connects the midpoint of AB (denoted as M) to the midpoint of BC (denoted as N) and is parallel to AC.

The length of the mid segment MN is equal to half the length of AC

(MN = 1/2 * AC).

we have,

For the given diagram, the midpoint is S, so the length RW cannot be the length of the mid segment.

Hence, The statement that cannot be true is "length RW is a mid segment of the triangle". option D.
