Answer:

14.4

Step-by-step explanation:

To find the mean in math, you add all of your numbers together, the divide by how many numbers you added together. So add 17,15,14,14, and 12 together to get 72. Divide 72 by 5 to get 14.4

Answer:

The mean would be 14.4 hours.

Step-by-step explanation:

In order to find the mean, or average, of the numbers, you would add all the numbers together.

17 + 15 +14 + 14 + 12 which equals 72

Then, you take the total which is 72, and divide it by how many numbers you added together which is 5.

72/5 = 14.4

Select the two binomials that are factors of this trinomial.

Stella [2.4K]

we are given

trinomial as

$x^2 -x -12$

now, we can factor it

$x^2 -x -12= x^2 -4x +3x -4*3$

$x^2 -x -12= x(x -4) +3(x -4)$

$x^2 -x -12= (x-4)(x+3)$

so, option-C and D ..............Answer

Simplify the expression. -2/3c -9/5 + 14c + 3/10

Andrew [12]

Answer:

$13 \frac{1}{3} c - 1 \frac{1}{2}$

Step-by-step explanation:

We want to combine alike terms so

-2/3c+14c & -9/5+3/10

14c-2/3

$\frac{14}{1} c - \frac{2}{3} c$

Multiply 14/1 by 3/3 to get the denominators the same

$\frac{42}{3} c - \frac{2}{3} c$

Subtract

$\frac{40}{3} c$

simplify

$13 \frac{1}{3} c$

now

$\frac{3}{10} - \frac{9}{5}$

Multiply 9/5 by 2/2

$\frac{3}{10} - \frac{ 18}{10}$

Subtract

$- \frac{15}{10}$

Simplify

$- 1 \frac{1}{2}$

put both together

$13 \frac{1}{3}c - 1 \frac{1}{2}$

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

In February, Alec had 1,562 visitors to his website. In March, he had 1,310 visitors to his website. What is the percentage decr

tigry1 [53]

Answer:

16.1% is the percentage decrease.

Step-by-step explanation:

We are given the following in the question:

Visitors in February = 1,562

Visitors in march = 1,310

We have to find the percentage decrease of the number of visitors to Alec's website from February to March.

Percentage decrease =

$=\dfrac{\text{Change}}{\text{Original}}\times 100\%\\\\=\dfrac{1562-1310}{1562}\times 100\%\\\\=\dfrac{252}{1562}\times 100\% = 16.1\%$

Thus, 16.1% is the percentage decrease in the number of visitors to Alec's website from February to March.
