A cube has an edge length of 10in. What is its volume, in cubic in?

Mathematics

Answer: 1,000

Step-by-step explanation:

The volume of a cube is the edge length cubed.

Therefore, if the edge length is 10in, the volume would be:

= 10^{3}

=1000

The volume of the cube is 1,000 inches cubed.

Answer:

V = 1000 in³

Step-by-step explanation:

The volume of a cube of side length s is V = s³.

If the side length is 10 in, then the volume, V, is (10 in)³, or V = 1000 in³

Answer:

Step-by-step explanation:

Mark the two points (-1,7) and (1,-1) on the graph.  Then draw a straight line between them.  To determine the equation that goes through these two points, we can use the two given points to find the slope of the line.  The standard form of a straight line equation is

y = mx + b,

where m is the slope and y is the y-intercept (the value of y when x = 0).

Slope is also known as the "Rise"/"Run" - the change in y divided by the change in x.  We can use the two points to calculate this:

       Rise (-1-(7) = -8   Run = (1 - (-1) = 2

The slope is therefore (-8/2) or -4.  

y = -4x + b

We can find b by entering either of the two points in y = -4x + b and solve for b.  I'll use (1,-1) since I have my 1's multiplication table memorized

y = -4x + b

-1 = -4(1) + b

b = 3

The straight line equation that connects the two points is

  y = -4x + 3

You can graph this equation (e.g., on DESMOS) to see how it intersects the points.  <u>[Attached]</u>

The coordinates of the y intercept are (0,3).

A final exam in Math 160 has a mean of 73 with standard deviation 7.8. If 24 students are randomly selected, find the probabilit
never [62]

A sample of size n taken from a population with mean = µ and standard deviation = σ has sample mean = µ and sample s.d. = σ/√n.

If the final exam scores are normally distributed, and X is a random variable for the mean of a sample, then

Pr[X < 70] = Pr[(X - 73) / (7.8/√24) < (70 - 73) / (7.8/√24)]

… ≈ Pr[Z < -1.8842]

… ≈ 0.0298

(where Z is normally distributed with µ = 0 and σ = 1).

a home health care assistant prepares 10 and a half ounces of formula the mixture is 1/3 formula and 2/3 water how much formula
Dimas [21]

Total amount of the mixture = 10\frac{1}{2}=10.5 ounces

Proportion of formula = \frac{1}{3}

Proportion of water = \frac{2}{3}

Amount of water needed to make the mixture can be given as:

Total amount of mixture x Proportion of water

Using the values, we get:

Amount of water needed = 10.5*\frac{2}{3} = 7 ounces

Similarly the amount of formula needed will be:

Total amount of mixture x Proportion of formula

Using the values, we get:

Amount of formula needed = 10.5*\frac{1}{3} = 3.5 ounces

Therefore, the home health care assistant needs 3.5 ounces of formula and 7 ounces of water to prepare 10 and a half ounces of formula.
