Answer:

1.) C. 32

2.) Stem-and-leaf plot

Step-by-step explanation:

This is a stem-and-leaf plot. The stem represents tens and the leaves represent units. To make it easier to look at, it is equivalent to this:

20, 28, 29, 29, 31, 32, 36, 41, 42

Now, to find the mean, add up all the numbers and divide the sum by the number of values.

(20 + 28 + 29 + 29 + 31 + 32 + 36 + 41 + 42)/9 = 288/9 = 32

I don’t get it it doesn’t make sense

san4es73 [151]

Answer:

Area of A = 32ft

Area of B = 36ft

Step-by-step explanation:

All you need to do to solve is multiply width * length * height.

If you do so,

Area of A = 3 * 2 * 5 1/3

= 6 * 16/3

= 32

Area of B = 6 * 4 * 1 1/2

= 24 * 3/2

= 36

Hope this helps!!

Let me know if I'm wrong or you need help in any other problem!!

What is the solution to 2(-4x+1)=2/3(x+2)

Rzqust [24]

Hello!

The answer to your problem is: $x=1/13$

Simplify both sides of the equation

$(2)(-4x)+(2)(1)=(2/3)(x)+(2/3)(2)$ $(Distribute)$

$-8x+2=2/3x+4/3$

Subtract 2/3x from both sides

$-8x+2-2/3x=2/3+4/3-2/3x$

$-26x+2=4/3$

Subtract 2 from both sides

$-26/3x+2-2=4/3-2$

$-26/3=-2/3$

Multiply both sides by 3/(-26)

$(3/26)*(-26/3x)=(3/-26)*(-2/3)$

Get your answer

$x=1/13$

Hope This Helps!

The function f(x)=g(x), where f(x)=2x-5 and g(x)=x^2-6. The table below shows the process of solving using successive approximat

valkas [14]

Answer:

The positive solution is 2.4.

Step-by-step explanation:

The given functions are

$f(x)=2x-5$

$g(x)=x^2-6$

It is given that

$f(x)=g(x)$

$2x-5=x^2-6$

$0=x^2-6-2x+5$

$0=x^2-2x-1$

The quadratic formula:

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$x=\frac{2\pm \sqrt{(2)^2-4(1)(-1)}}{2(1)}$

$x=\frac{2\pm \sqrt{8}}{2}$

$x=\frac{2\pm 2\sqrt{2}}{2}$

$x=\frac{2(1\pm \sqrt{2})}{2}$

$x=1\pm \sqrt{2}$

$x=2.4,-0.4$

Therefore the positive solution is 2.4.
