hi, i need help finding the mean and standard deviation. the reeses pieces are just a filler for the sample subject.

Answer: The slope is 4/5 and the y-intercept is (0,-1)

Step-by-step explanation:

What is equation of straight line in slope-intercept form?

The formula for equation of straight line in slope-intercept form is y = mx +c

where m = slope and c = y-intercept

Analysis

y2-y1/x2-x1

3-(-1)/5-(-0)

=4/5

The slope of the linear function is 4/5

The y-intercept is (0.-1)

ANSWER

P'(-12, 21.5)

EXPLANATION

We are given the cordinates of P as:

P(-9, 10.5)

Cordinate points are given as A(x, y)

We want to translate it 3 units left and 11 units up.

That means that we are moving it 3 units towards the negative side of the x axis and 11 units towards the positive side of the y axis.

Therefore, we will subtract 3 from the x cordinate and add 11 to the y cordinate.

Therefore, the translation is:

P(-9, 10.5) => P'(-9 - 3, 10.5 + 11)

=> P'(-12, 21.5)

The cordinates of P have been translated.

Explanation:

Given the expression

First, we evaluate the bracket and exponents.

This then gives us:

The lower-of-cost-or-net-realizable-value of the inventory is $31000.

An asset's worth is often assessed using the net realizable value (NRV) approach for inventory accounting. It is discovered by calculating the difference between the asset's anticipated selling price and all of the expenses related to the asset's eventual sale. The cash sum that a corporation anticipates receiving is known as net realizable value (NRV). Consequently, net realizable value is also known as cash realizable value. The terms "net realizable value" and "current assets" are frequently used in relation to inventory and accounts receivable.

Given,

Camera

Cost = 11600

Market value = 10100

(Market value is less. so 10100.)

Camcorders

Cost = 8500

Market value = 8000

( Market value is less so 8000)

DVD

Cost = 13500

Market value = 12900

(Market value is less, so 12900)

the lower-of-cost-or-net-realizable-value of the inventory:

= 10100 + 8000 + 12900

= 31000

The lower-of-cost-or-net-realizable-value of the inventory is $31000.

Okay, here we have this:

Considering that the range of a function is the complete set of all possible resulting values of the dependent variable (y), we can see in the graph of the function that:

The values of the variable "y" go from -1 to plus infinity, this mean that the range is:

-1≤y<∞

Finally we obtain that the correct option is the first option.

The margin of error of a z-confidence interval is given by: [tex]$M=z \frac{\sigma}{\sqrt{n}}$$[/tex]

The margin of error of a z-confidence interval is 142.945936.

The margin of error of a z-confidence interval exists given by:

[tex]$M=z \frac{\sigma}{\sqrt{n}}$$[/tex]

Where, z is the critical value.

[tex]$\sigma$[/tex] be the population standard deviation.

n is the sample size.

The first step is finding the critical value, which exists z with a p-value of [tex]$\frac{1+\alpha}{2}$[/tex] in which [tex]$\alpha$[/tex] is the confidence level.

In this problem, [tex]$\alpha[/tex] = 0.95, therefore, z with a p-value of 1 + 0.95 / 2 = 0.975, which means that it is z = 1.96.

The population standard deviation exists of 12.2 meters, thus [tex]$\sigma[/tex] = 12.2.

We want a width of 5 , thus a margin of error of M = 2. Therefore, we have to simplify the equation for the margin of error for n.

Let the equation be [tex]$M=z \frac{\sigma}{\sqrt{n}}$$[/tex]

substitute the  values in the above equation, we get

[tex]$2=1.96 \frac{12.2}{\sqrt{n}}$[/tex]

[tex]$2 \sqrt{n}=1.96(12.2)$[/tex]

simplifying the above equation, we get

[tex]$\sqrt{n}=\frac{1.96(12.2)}{2}$[/tex]

[tex]$(\sqrt{n})^2=\left(\frac{1.96(12.2)}{2}\right)^2$[/tex]

n = 142.945936

Therefore, the value of n = 142.945936.

The area, in square feet, of the portion of the garden that excludes the border is 40.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

We have been given that Angie added a stone border of 2 feet in width on all sides of her garden making her harder 12 by 6 feet.

Length = 12 ft

Width = 6 ft

The dimension of the garden  that excludes the border of 2 feet are;

Length = 12 ft- 2 = 10 ft

Width = 6 ft - 2= 4 ft

Thus, Area  =  length × Width

Area = 10 x 4

Area = 40 square feet

Hence, the area, in square feet, of the portion of the garden that excludes the border is 40.

Step-by-step explanation:

Solution

If the total amount of hand lotion is available, then you have 128 ounces of hand lotion.

If 128 oz is put into a number of smaller containers (each one 4 oz) then you have

128/4 containers.

128 / 4 = 32.

You can make 32 containers each one holding 4 ounces. The question uses division to solve.

1) Let's rewrite it as a logarithmic expression of the following exponential one. Let's do it step by step.

Note that when we apply the natural log on both sides, we use one of those properties that tell us that we can eliminate the log since the base of a natural log is "e", as well as, "e" is the base of that power.

2) To rewrite in the exponential form we can do the following:

Note that in this case, we have used the definition of logarithms.

the given function is a quadratic function

The graph of the function is as shown in the following picture

As shown the function has a minimum point at ( 4, 5 )

So, vertex = ( 4, 5 )

And Axis of symmetry: x = 4

Answer: so lets say x =the exact amount of rows

so each row has 5 tree's

then a is the answer

its an equation of x·5=a

so that would be a unknown number of trees so you assume that there is more than 1 row because there is several rows so its a incomplete question

Step-by-step explanation:

True

Note that when you have the position of a point as (x, y), the first coordinate is the x - axis while the second is the y - axis.

Also note that, to the right of the x axis, you have positive numbers while you have negative numbers to the left.

We can then conclude that When the first coordinate is positive, that point is located to the right of the x-axis

The angles are 22.5°, 67.5° and 90°.

Let the smallest angle = x

Total angles in a triangle = 180°

One angle is three times the smallest angle. This will be 3x.

The third angle is 45 more than twice the smallest angle. This will be:

= (2 × x) + 45

= 2x + 45

The angles will be:

x + 2x + 45 + 3x = 180

6x + 45 = 180

Collect like terms

6x = 180 - 45

6x = 135

Divide

x = 135 / 6

x = 22.5°

Smallest angle = 22.5°

The other angles will be calculated by substitutibg 22.5° for x. This will be:

3x = 3 × 22.5 = 67.5°

Also, 2x + 45 = 2(22.5) + 45 = 90°
