-3 and 1/3 would be the correct answer. Rise/run. If you count, since its on a graph, one of them is 2/6 which reduces down to 1/3 positive slope. Then the other is -3/1 which reduces down to -3 slope.

scoray [572]

Answer: 2.46

Step-by-step explanation:

Formula for x-score is given by :-

Z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

, where \overline{x} = Sample mean , \mu= population mean, \sigma = population standard deviation, n= sample size.

As per given , n=10

\mu= $29,056

\sigma = $3,339

\overline{x} =  $31,650

Then,

z=\dfrac{ 31650-29056}{\dfrac{3339}{\sqrt{10}}}\\\\=\dfrac{2594}{\dfrac{3339}{3.16227766017}}\\\\=\dfrac{2594}{1055.88451073}=2.45670807142\approx 2.46

Hence, the z-score = 2.46

What is the length of bc in the right triangle below
worty [1.4K]
To solve for this, we need to use Pythagorean Theorum.
Pythagorean Theorum is when we add the squares of the legs (A & B) to solve for the hypotenuse (C) or the side that's across from the 90 degree angle.
The formula for Pythagorean Theorum is A^2 + B^2 = C^2.

We have our two leg lengths, 15 and 36 (A & B).
Square 15 and 36.
15^2 = 225
36^2 = 1,296

Now that we have our side lengths, let's add them up.
225 + 1,296 = 1,521.

Now, to solve for C, we need to square root our sum.

The square root of 1,521 is 39.

Your hypotenuse is 39.

Your answer is C.) 39.

I hope this helps!

A box in the shape of a rectangular prism is approximately 9 inches long,has an equilateral triangle shaped base with side lengt
vfiekz [6]

Answer:

33.75 cubic inches of styrofoam can be placed inside the container.

Step-by-step explanation:

Based on given information, the volume of the prism (V), in cubic inches, is determined by using this formula:

V = \frac{1}{2}\cdot b\cdot h \cdot l (1)

Where:

b - Base of the triangular face, in inches.

h - Height of the triangular face, in inches.

l - Length of the prism, in inches.

If we know that b = 3\,in, h = 2.5\,in and l = 9\,in, then the volume of the prism is:

V = \frac{1}{2}\cdot b\cdot h \cdot l

V = 33.75\,in^{3}

33.75 cubic inches of styrofoam can be placed inside the container.
