Answer:

Dogs: 44.44 Cats: 55.556

Step-by-step explanation:

*this is only if you are allowed to use a calculator*

1. You have to add the total of the cats and dogs

Why? Here, let me put it this way. You have a test with two sections: math and science. If there are 2 Maths Questions and 2 Science questions, what percent of the test are math questions? You would not say 2/2 and say 100. You would say 2/4 because it is obvious. You do the same in this case but it is not as noticeable because you are dealing with bigger numbers.

15 + 12 = 27.

2. Solve

a. There are 15 dogs and 12 cats that makes up 27 pets total.

So you have to do 12/27 for cats,

15/27 for dogs. The fractions equal one and It shows you how much of one is there compared to the total.

b. Simplify

You can simplify these fractions:

for 12/27, divide the numerator and the denominator by 3.

You get 4/9

Divide 15/27 for dogs by 3 as well to get 5/9.

5+4 is 9, which means that I am doing the math correctly.

According to the calculator, 5/9 is 55.556, and 4/9 is 44.444

They should be accurate because there are more dogs than cats and the percentage for dogs are higher. Hence, this is correct.

Cats = 4/9 = 44.444%

Dogs = 5/9 = 55.556%

Hope this helps :)

The value of alpha is 0.26, assuming a confidence level of 74%.

The significance level α is the probability of making the wrong decision when the null hypothesis is true.

Alpha levels which is also called as significance levels are used in hypothesis tests.

Given

When finding the margin of error for the mean of a normally distributed population from a sample.

The confidence interval = 74% = 0.74.

The value of the alpha is given by;

[tex]\rm \alpha =1- Confidence \ interval[/tex]

Substitute all the values in the formula

[tex]\rm \alpha =1- Confidence \ interval\\\\\alpha=1-0.74\\\\\alpha=0.26[/tex]

[tex]\: {\qquad \sf \dfrac{4}{6} x + \dfrac{10}{4} = - \dfrac{6}{8}x - 10 }[/tex]

⠀

To Find :

⠀

Solution :

[tex] {\qquad \sf \dashrightarrow \: \dfrac{4}{6} x + \dfrac{10}{4} = - \dfrac{6}{8}x - 10 }[/tex]

⠀

Subtracting [tex] \sf \: \dfrac{10}{4} [/tex] from both sides :

[tex] {\qquad \sf \dashrightarrow \: \dfrac{4}{6} x \: \: \cancel{+ \dfrac{10}{4}} \: \: \cancel{- \dfrac{10}{4}} = - \dfrac{6}{8}x - 10 - \dfrac{10}{4} }[/tex]

⠀

Adding [tex] \sf \dfrac{6}{8} x[/tex] to both sides :

[tex]{\qquad \sf \dashrightarrow \: \dfrac{4}{6} x + \dfrac{6}{8}x = \cancel{- \dfrac{6}{8}x } \: \: \cancel {+ \: \dfrac{6}{8}x} - 10 - \dfrac{10}{4} }[/tex]

[tex]{\qquad \sf \dashrightarrow \dfrac{4}{6} x + \dfrac{6}{8}x = - 10 - \dfrac{10}{4}}[/tex]

⠀

Adding the like terms :

[tex]{\qquad \sf \dashrightarrow \dfrac{32x + 36x}{24} = \dfrac{ - 40 - 10}{4} }[/tex]

[tex]{\qquad \sf \dashrightarrow \dfrac{68x}{24} = \dfrac{ - 50}{4} }[/tex]

[tex]{\qquad \sf \dashrightarrow \dfrac{34x}{12} = \dfrac{ - 25}{2} }[/tex]

⠀

By doing cross multiplication we get :

[tex]{\qquad \sf \dashrightarrow {68x} = - 300 }[/tex]

[tex]{\qquad \sf \dashrightarrow {x} = \dfrac{ - 300}{68} }[/tex]

[tex]{\qquad \bf \dashrightarrow {x} = \dfrac{ - 75}{17} }[/tex]

[tex] \frac{1}{2} (29 - x) = 7.75[/tex]

[tex] \frac{1}{2} ( - x + 29) = 7.75[/tex]

[tex] \frac{1( - x + 29)}{2} = 7.75[/tex]

[tex] \frac{ - x + 29}{2} = 7.75[/tex]

[tex]2· \frac{ - x + 29}{2} = 2·7.75[/tex]

[tex] - x + 29 = 2·7.75[/tex]

[tex] - x + 29 = 15.5[/tex]

[tex] - x + 29 = 15.5 - 29[/tex]

[tex] - x = - 13.5[/tex]

[tex] \frac{ - x} {- 1} = \frac{ - 13.5 }{ - 1 } [/tex]

[tex]x = 13.5[/tex]

So, the value of x is 13.5.

We know that, The formula for the surface area of a sphere of radius

R is 4πR².

here, we have,

According to question, we have the radius of sphere as 3 units.

So, surface area of a sphere

⇒4πR²

⇒4π(3)²

⇒36π

The surface area of a sphere is given by

SA = 4 pi r^2

SA = 4 * pi * 3^2

SA =36 pi

SA =113.10

Hence, the surface area of the sphere is 36π unit².

The price-demand relationship of the company is a linear model

The equation that models the price-demand relationship is y = -20x + 1960

From the question, we have the following points:

(x, y) = (88, 200) and (38, 1200)

The equation of the linear relationship is then calculated as:

[tex]y = \frac{y_2 - y_1}{x_2 -x_1} * (x - x_1) + y_1[/tex]

Substitute known values in the above equation

[tex]y = \frac{1200 - 200}{38 -88} * (x - 88) + 200[/tex]

Evaluate the difference

[tex]y = \frac{1000}{-50} * (x - 88) + 200[/tex]

Evaluate the quotient

[tex]y = -20 * (x - 88) + 200[/tex]

Expand

[tex]y = -20x + 1760 + 200[/tex]

Evaluate the sum

[tex]y = -20x + 1960[/tex]

Hence, the equation that models the price-demand relationship is y = -20x + 1960

x+10 =5 that is the answer because look at the example

Answer:

3)  48 units²

6)  46 units²

Step-by-step explanation:

Question 3

This shape is a parallelogram with base of 8 units and height of 6 units.

Area of a parallelogram = base × height

                                        = 8 × 6

                                        = 48 units²

Question 6

This shape is a quadrilateral.  It is made up of 3 triangles and a rectangle (see attached image for how to divide the quadrilateral)

Area of rectangle = width × length

                              = 4 × 6

                              = 24 units²

Area of a triangle = 1/2 × base × height

Triangle 1:   1/2 × 2 × 4 = 4 units²

Triangle 2:   1/2 × 6 × 2 = 6 units²

Triangle 3:   1/2 × 4 × 6 = 12 units²

Total area = 24 + 4 + 6 + 12 = 46 units²

The value of A in solving the considered quadratic equation by completing the squares method is given by: Option

Suppose the considered quadratic equation is of the form [tex]ax^2 + bx + c = 0[/tex]

Then, completing the squares method tries to make a squared term in terms of x in the left side, so that x comes in linear form, instead of quadratic, as shown below:

[tex]ax^2 + bx + c = 0\\ax^2 + bx = -c\\\\\text{Multiplying 4a on both the sides}\\4a^2x^2 + 4abx = -4ac\\\\\text{Adding }b^2\text{ on both the sides}\\4a^2x^2 + 4abx + b^2 = b^2 -4ac\\or\\(2ax +b)^2 = b^2 - 4ac\\2ax + b = \pm \sqrt{b^2 - 4ac}\\\\x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

This provides two solution to the considered quadratic equation. These solutions can be real, or imaginary.

For the considered case, the quadratic equation is:

[tex]10x^2 + 40x - 13 = 0[/tex]

Applying the method as Isoke did, we get:

[tex]10x^2 + 40x - 13 = 0\\10x^2 + 40x = 13\\10(x^2 + 4x) = 13[/tex]

Therefore, we get the value of A as 10.

The shape on the very left of the picture is not a quadrilateral. However, the three other shapes are quadrilaterals.

The scatterplot can show an association or no association, at all.

The type of association shown by the graph that relates test grades and shoe sizes of the students in Dexter's class is no association

When the points on the graph of the scatter plot follows an approximately, straight line; then the relationship is a linear relationship.

If it follows a curve, then it is a nonlinear relationship

If the points are scattered, then it shows no association.

The points on the graph are scattered, and they do not follow a specific pattern.

Hence, the graph shows no association

Answer:

329.9 ft^2

Step-by-step explanation:

area = π · r^2

diameter = 2r so radius = 10.25

area = 3.14 · 10.25^2

10.25^2 = 105.06

3.14 · 105.06 = 329.9 ft^2

Given :-

[tex] \\ \\ [/tex]

To find :-

[tex] \\ \\ [/tex]

Solution:

To find area first we should know value of radius.

Diameter is given , and from diameter we can find value of radius.

[tex] \\ [/tex]

We know :-

[tex] \bf \ddag\boxed{\rm Diameter =2 \: radius } \bf \ddag[/tex]

By using this formula we can find radius.

[tex] \\ \\ [/tex]

[tex] \hookrightarrow\sf Diameter =2 \: radius [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf 20.5 =2 \: radius [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf \dfrac{205}{10} =2 \: radius [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf \cancel\dfrac{205}{10} =2 \: radius [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf \dfrac{41}{2} =2 \: radius [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf2 \: radius = \dfrac{41}{2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf \: radius = \dfrac{41}{2 \times 2} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\sf \: radius = \dfrac{41}{4} [/tex]

[tex] \\ [/tex]

[tex] \hookrightarrow\bf \: radius = 10.25[/tex]

[tex] \\ \\ [/tex]

Now let's find Area

we know :-

[tex] \bf \ddag\boxed{\rm Area = \pi radius {}^{2} } \bf \ddag[/tex]

[tex] \\ \\ [/tex]

So:-

[tex] \\ [/tex]

[tex] \dashrightarrow \sf Area = \pi radius {}^{2} [/tex]

[tex] \\ \\ [/tex]

[tex] \dashrightarrow \sf Area = \pi (10.5) {}^{2} [/tex]
