Answer: Janelle can fill 6 feeders.

Step-by-step explanation:

To find the number of feeders Janelle can fill, we need to divide the total amount of bird food she has by the amount of bird food each feeder can hold.

First, let's convert the total amount of bird food from cups to half-cups:

3 cups / 2 = 6 half-cups

So, Janelle has 6 half-cups of bird food, and each feeder can hold 1 half-cup.

Therefore, she can fill:

6 half-cups / 1 half-cup per feeder = 6 feeders.

So, Janelle can fill 6 feeders.

The sum of the capitals would be $530400.

The formula to calculate the simple interest is -

I = PRT/100

Given is that a capitalist has two capitals that differ in $221,000. The largest of them imposes it at 20% per year and the smallest at 16% per year, so after 3 years, the amount produced by the largest is double what the smallest produces.

We can write the amount produced by largest as -

A = P(1 + rt)

A = 221000(1 + 0.2 x 3)

A = 221000 x 1.6

A = 353600

Amount generated by smallest -

a = 353600/2

a = 176800

Their sum would be -

A + a = 530400

Therefore, the sum of the capitals would be $530400.

The two smaller angles are 39 degrees each. The other angle is 106

The measure of the angles would be found using the formula

2*x + 24 = 180

This is because the sum of angles that are in a triangle is = 180

the two equal angles are x + x = 2x

The statement that correctly defines continuous and discrete quantitative variables is:

"A continuous variable can take on any real number value within some range, whereas a discrete variable come in countable units."

A variable is a quantity that may assume any one of a set of values.

This means that a continuous variable can take on any value within a certain range, which could be infinite, and that it can have decimal values. In contrast, a discrete variable has specific values that are separate and countable, such as integers or categories. For example, the height of individuals is a continuous variable, while the number of siblings someone has is a discrete variable.

Spreadsheet software is strongly recommended. If you have excel, then it's best to use it since it's used practically everywhere. If you don't have excel, then there are tons of free alternatives such as OpenOffice or LibreOffice.

Enter the data as shown. Then form a third column labeled xy which represents multiplying each x and y pair for any given row. Eg: Tom = xy = 7*2 = 14. Use cell references to quickly compute this new column. I don't recommend manually multiplying each pair of items.

Once the xy column is formed, add up everything in it since [tex]\Sigma[/tex] represents summations. The command called "Sum" or "SUM" does this very quickly. In a cell off to the side type in [tex]=Sum(C2:C10)[/tex] which will add up the elements in cell C2, C3, ... all the way up to C10. Don't forget about the equal sign up front.

Answer:

Step-by-step explanation:

Generally an equation which will be true for all values of x have some statement which can be simplified into another state which will always be true.

So for example: [tex]x+4=x+4[/tex], is kind of a bit obvious to tell it's going to be true for all values as the two expressions have the same exact terms, but we can subtract "x" from both sides leading us to the statement: [tex]4=4[/tex] which is always true.

One important thing to note is you must be cautious at times, for example: [tex]\frac{x-2}{x-2}=\frac{x-2}{x-2}[/tex] may seem to be true for all values, and x-2 over x-2 is the same thing, so it simplifies to one and same thing on the right side: [tex]1=1[/tex] thus the statement should be true for all values right? Not completely, it's true for most values, except for x=2, and this is because 1=1 isn't exactly the same expression. In the original fraction the denominator has an x-2, and if we plug in x=2, we get 2-2 resulting in division by one, which of course isn't definable. So that's just one important thing to note as simplifying expressions may result in expressions that look equal, but are slightly different in a way.

The domain of the relation include the following: C. {-5, -2, 0, 1, 4}.

In Mathematics, the horizontal extent of any graph of a function represents all domain values and they are always read and written from smaller to larger numerical values, and from the left of the graph to the right.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain:

Domain = {-5, -2, 0, 1, 4}.

In conclusion, the domain of this relation are all the x-values (independent value) that are located on the x-axis of the graph, which include {-5, -2, 0, 1, 4}.

Answer:

[tex]6\pi[/tex]

Step-by-step explanation:

There's two things to note here, we're dealing with a semi-circle and also a semi-circle that has some area taken out of it.

The area of a circle can be calculated using the formula: [tex]A=\pi r^2[/tex] where "r" is the radius, equal to half the diameter.

Since we're dealing with the semi-circles, we can just divide this area by two to get: [tex]A=\frac{\pi r^2}{2}[/tex]

Now as noted, we have some of the area taken out, but fortunately it's just another semi-circle. We can simply calculate the area of the entire semi-circle, and then calculate the area of the semi-circle inside and subtract them.

So the diameter of the entire thing is just 8 ft, so the radius is half of this, equal to 8 ft. That means the area is: [tex]A=\frac{\pi (4)^2}{2}=A = \frac{\pi * 16}{2} = 8\pi[/tex]

One mistake that may be made here, is assuming the radius of the smaller semi-circle is just two, as provided in the image. It's actually the radius of the inner semi-circle plus two which gives us the radius of the outer circle, of 4 feet. Now luckily in this case, it actually still results in 2 ft (since 2 + 2 = 4), but in other examples, that may noe be the case.

So now let's calculate the area of the inner semi-circle: [tex]A=\frac{\pi (2)^2}{2}=2\pi[/tex]

Now let's just subtract the areas: [tex]8\pi - 2\pi = 6\pi[/tex], so the area is 6 pi

The measure of the length of x is equal to 20.1246 using the trigonometric ratios of cosine for angle C

The trigonometric ratios involves the relationship of an angle of a right-angled triangle to ratios of two side lengths. Basic trigonometric ratios includes; sine cosine and tangent.

Considering the right triangles; ∆ABC with hypotenuse = 45 and adjacent = BC, the triangle ∆ADC with hypotenuse = BC and adjacent = 9 with the angle C we can solve for BC as follows:

for ∆ABC;

cosC = 9/BC {adjacent/hypotenuse}

for ∆ADC;

cosC = BC/45 {adjacent/hypotenuse}

9/BC = BC/45

BC² = 9 × 45 {cross multiplication}

BC² = 405

BC = √405 {take square root of both sides}

BC = 20.1246

Therefore, the measure of the length of x is equal to 20.1246 using the trigonometric ratios of cosine for angle C

How to calculate the Volume of Composite Shapes?

Composite shapes have a volume that is made up of basic shapes. We can calculate the volume of the composite shapes using the steps listed below:

Step 1: Break down the compound shape into different components.

Step 2: Determine the volume of each basic shape.

Step 3: Combine the volumes of all the basic shapes.

Step 4: Write the solution in cubic units.

Firstly we can divide the figure into two rectangular prisms A and B. Then add these two to total volume the volumes of each prism.

The volume of prism A = length × width × height

V = 4 * 2 * 1

V = 8 cubic in.

The volume of prism B = length × width × height

V  = 1 * 2 * 2

V = 4 cubic in.

Total volume = volume of prism A + volume of prism B

= 8 cubic in + 4 cubic in

= 12 cubic in

Step-by-step explanation:

THE ANSWER TO YOUR QUESTION IS C.

Answer:

Step-by-step explanation:

The y-intercept of a linear equation in slope-intercept form, y = mx + b, represents the point at which the line crosses the y-axis. In this form, "m" represents the slope of the line and "b" represents the y-intercept.

If we have a graph of y = -9x + 11, the y-intercept can be found by setting x equal to 0 and solving for y:

y = -9x + 11

y = -9 * 0 + 11

y = 11

So, the y-intercept of the original graph is (0, 11).

Now, if we have a graph of y = -9x + 14, the y-intercept can be found in the same way:

y = -9x + 14

y = -9 * 0 + 14

y = 14

So, the y-intercept of the new graph is (0, 14).

Comparing the y-intercepts of the two graphs, we can see that the y-intercept of the new graph has shifted up by 3 units, from (0, 11) to (0, 14).

Therefore, the correct answer is A: The y-intercept of the new graph would shift up 3 units.

The null hypothesis H0 in this case would be that the standard deviation of the number of accidents per day is equal to 0.04, while the alternative hypothesis Ha would be that the standard deviation of the number of accidents per day is not equal to 0.04.

The null hypothesis represents the status quo or the default assumption, which is that there has been no change in the standard deviation of the number of accidents per day. The alternative hypothesis represents the claim made by the actuaries, which is that there has been a change in the standard deviation.

Mathematically, the null and alternative hypotheses can be expressed as follows:

H0: σ = 0.04

Ha: σ ≠ 0.04

where σ represents the standard deviation of the number of accidents per day.

The hypothesis test would be used to determine whether there is evidence to support the actuaries' claim that the standard deviation has changed, or whether there is not enough evidence to reject the null hypothesis that the standard deviation remains equal to 0.04.
