Answer:

Step-by-step explanation:

starting equation is 15=0.75(x)+5.

You have to have the numbers on one side so...

15-5=10, and 5-5=0.

now, our equation is 10=0.75(x).

we are looking for x, so....

10/.75= 13 and 1/3.

since there is no such thing as a third of a song, 13 would be our number.

<h3>Given:</h3>

w= 6 units
h= 6 units
l= 10 units

w: width
h: height
l: length

The volume of the given triangular prism.

<h3>Solution:</h3>

Triangular prism is a 3 sided prism with same area of cross section with 2 triangular bases.

$\large\boxed{Formula: V= \frac{wl}{2}×h}$

Let's solve!

First, let's multiply width and height.

$6×6$

$= 36$

Now, we'll have to divide the answer by 2.

$\frac{36}{2}$

$= 18$

Then, multiply the answer by length.

$18×10$

$\large\boxed{V= 180 \: {units}^{3}}$

Hence, the volume of the given triangular prism is 180 cubic units.

The Lane School sold 1,152 granola bars to raise money for digital cameras. All the granola bars were either berry bars or raisi

Answer:

26 boxes of raisin bars

Step-by-step explanation:

Take the total bars sold 1152 then subtract the berry bars 528 and you'll get 624. Next you'll divide the 624 by 24 because that's how many that's in a full box. Finally you'll get your answer of 26 boxes.

1152-528=624 ➗ 24 = 26

Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers

Alenkinab [10]

Given:

$\sigma_A=3$

$n_A=6$

$\sigma_B=5$

$n_B=4$

$\overline{x}_A=\overline{x}_B$

To find:

The variance. of combined set.

Solution:

Formula for variance is

$\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}$ ...(i)

Using (i), we get

$\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}$

$(3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}$

$9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}$

$54=\sum (x_i-\overline{x}_A)^2$

Similarly,

$\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}$

$(5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}$

$25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}$

$100=\sum (x_i-\overline{x}_B)^2$

Now, after combining both sets, we get

$\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}$

$\sigma^2=\dfrac{54+100}{6+4}$

$\sigma^2=\dfrac{154}{10}$

$\sigma^2=15.4$

Therefore, the variance of combined set is 15.4.

Steps to solve 10.3=0.6y solve the y

Nat2105 [25]

All you need to do is divide 0.6 into both sides.

10.3/0.6= 17.166666666667 ( you could round up to 17.2)

I hope this helps!
