Answer:

The surface area is 177 square inches

Step-by-step explanation:

Given

[tex]Length = 10[/tex]

[tex]Width = 3[/tex]

[tex]Height = 4\frac{1}{2}[/tex]

Required

The surface area

This is calculated as:

[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

So, we have:

[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]

[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]

[tex]Area = 2 * (88\frac{1}{2})[/tex]

[tex]Area = 177[/tex]

Answer:

(-6, -4)

Step-by-step explanation:

Original coordinates: (6, -4)

POINT S IS 12 UNITS TO THE LEFT OF POINT P.

There are multiple ways to solve this, but I will explain the easiest way.

We can subtract 12 from the x-coordinate.

This because the x-axis runs RIGHT and LEFT.

The y-axis runs UP and DOWN.

6 - 12 = -6

The y-coordinate stays the same.

The new coordinates are: (-6, -4).

7- The volume of a rectangular pyramid is:

We just have to substitute the values:

8- The volume of a cone is:

Let's substitute the values and solve:

If you want to round it, the answer will be:

9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.

So,

10- The volume of the cone is V = hπr² / 3

Then,

9 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.

If you want to round it to the nearest tenth, the answer is:

Answer:

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

Step-by-step explanation:

The data given is

               Today               Five Years Ago

X`                 81                           85

σ              14.5                        8.5

n                81                          36

The point estimate for the difference between the means of the two populations is x1`-x2`= 81-85=-4 where x1` is the mean of the of the first population and x2` is the mean of the second population.

The test statistics that will be used is

Z= x1-x2/ √σ₁²/ n₁ + σ₂²/n₂

Z=  81- 85/ √14.5² /81 + 8.5² /36

z= -4/√210.25/81+ 72.25/36

z= -4/2.1454

z= -1.8644

9. Multiply the money he has by the portion he spent:

75 x 3/5 = (75 x3)/5 = 225/5 = 45

He spent $45

10. First rewrite 4 1/8 as an improper fraction

33/8

Now multiply by 1/3:

33/8 x 1/3 = (33 x1) /(8 x 3) = 33/24 = 1 3/8

She spent 1 3/8 hours studying math.

Answer: 57.75 m

Explanation: First do 5 times 0.25. (The 0.25 is the same as 1/4.) Now take that answer and multiply it by 11. Your equation should look like this: 11*(5 1/4).

* = times

Answer:

Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

We have that:

1/10 of a scarf - 4/5 of an hour

x of a scarf - 1 hours.

Applying cross multiplication:

[tex]\frac{4x}{5} = \frac{1}{10}[/tex]

[tex]x = \frac{5}{10*4} = \frac{5}{40} = \frac{1}{8}[/tex]

Amy can knit [tex]\frac{1}{8}[/tex] of a scarf in 1 hour.

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.

Option B is the correct answer.

Standard deviation is a measure of the amount of variability or spread in a set of data.

It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.

We have,

The z-value formula is used to determine the number of standard deviations a data point is from the mean.

To determine the lower price of appetizers, we want to find a price that is significantly lower than the average cost.

Since the new restaurant wants to offer appetizers for a much lower price, we should use a z-value that is less than -1, which indicates a price that is more than one standard deviation below the mean.

Recall that the z-value formula is:

z = (x - μ) / σ

where x is the value of interest, μ is the mean, and σ is the standard deviation.

Thus,

By using a z-value less than -1, we can find a price that is significantly lower than the average cost, and therefore more likely to attract customers.
