TTM </3

Step-by-step explanation:

(x + 20)º and (4x - 5)º are supplementary angles, meaning the sum of their angles = 180º.

(x + 20) + (4x - 5) = 180

5x + 20 - 5 = 180

5x + 15 = 180

5x = 165

165/5 = 33

The test is to find out if there is a difference in the proportion of the number of autism in two samples differentiated by the use of vitamins.

The test statistic for the test is approximately 2.98

The p-value associated is 0.0028

Reasons:

The given parameters are;

[tex]\begin{array}{|l|c|c|c|}&\mathbf{\underline{Autism}}&\mathbf{\underline{Typical \ Development }}&\mathbf{\underline{Total}}\\No \ vitamin&111&70&181\\Vitamin&143&159&302\\Total&254&229&483\end{array}\right][/tex]

The null hypothesis is H₀; [tex]\hat{p}_1 = \hat{p}_2[/tex]

The alternative hypothesis is Hₐ; [tex]\hat{p}_1 \neq \hat{p}_2[/tex]

Where:

[tex]\hat{p}_1[/tex] = The proportion of the sample that did not use vitamin and had autism

[tex]\hat{p}_2[/tex] = The proportion of the sample that used vitamin and had autism

The test statistics for the difference of two proportions is given as follows;

[tex]Z=\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p}\cdot (1-\hat{p}) \cdot \left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}[/tex]

Where;

n₁ = 181, n₂ = 302, [tex]\hat p_1 = \dfrac{111}{181}[/tex],  [tex]\hat p_2 = \dfrac{143}{302}[/tex], [tex]\hat p = \dfrac{111 + 143}{181 + 302 } = \dfrac{254}{283}[/tex]

[tex]The\ test\ statistics,\, Z=\dfrac{\dfrac{111}{181}-\dfrac{143}{302}}{\sqrt{ \dfrac{254}{283}\cdot (1-\dfrac{254}{283}) \times \left (\dfrac{1}{181}+\dfrac{1}{302} \right )}} \approx 2.98[/tex]

The test statistic for the test, Z ≈ 2.98

From the Z-table, we have Z > 2.98 = 1 - 0.9986, therefore, given that the

alternative hypothesis [tex]\hat p_1 \neq \hat p_2[/tex], the p-value is 2 × (1 - 0.9986) = 0.0028

The p-value associated with the test is 0.0028

Answer:

x = 6 degrees

Step-by-step explanation:

A straight line is 180 degrees and we can make out three angles the form it, this means the three of them add to 180 using the straight angle theorem:

5x + x + 54 + 90 = 180

6x + 144 = 180

6x = 36

x = 6

Answer: 54

Step-by-step explanation:

A cube is a perfect square to find the area use L x W and if the length is 3, the width is 9

A cube has 6 sides, so 9 x 6 = 54

The total area of all the faces of the cube is 54 square meters.

Let's dive into finding the total area of all the faces of a cube.

A cube is a special type of three-dimensional shape where all its sides (called faces) are equal squares.

In your case, each face has a side length of 3 meters.

Now, to find the total surface area of the cube, we need to calculate the area of each face and then add them up.

The formula to find the area of a square is side length squared, which is [tex]\(A = s^2\)[/tex], where [tex]\(A\)[/tex] is the area and [tex]\(s\)[/tex] is the side length.

So, for your cube, each face's area is [tex]\(3^2 = 9\)[/tex] square meters. Since a cube has 6 faces,

we simply multiply the area of one face by the number of faces: [tex]\(6 \times 9 = 54\)[/tex] square meters.

To sum it up, the total area of all the faces of the cube is 54 square meters.

This is calculated by finding the area of one face and then multiplying it by the total number of faces.

In this case, each face has an area of 9 square meters, and a cube has 6 faces, resulting in a total area of 54 square meters.

Answer:

the snail travels 30 mm per minute

Step-by-step explanation:

Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.

the snail travels 30 mm per minute

Answer:

The value of y is decreasing for all real values of x (-∞,∞).

Step-by-step explanation:

Seeing as we have a simple 1st power equation, the slope will remain the same.  So, we solve for slope to see if this equation is for an increasing or a decreasing line.

y = mx + b, where m = the slope of the line

Is the standard slope form of a line, which matches the one given.

so in our equation, f(x) = -2x -3, our m value is -2.

Seeing as -2 is less than 0, the answer is:

The value of y is decreasing for all real values of x (-∞,∞).

Answer:

$8300

Step-by-step explanation:

First, you need to know the formula for this type of question.

The formula is I = Prt. These variables are: I = Interest, P = Principle investment, r = Rate, and t = Time.

Your equation will be 581 = P(0.07)(1), since 0.07*1 is 0.07, you'll earn only 7% interest.

So, we broke down the equation to 581 = P(0.07), and you have to isolate P.

Since you have to isolate P, you divide 0.07 from both sides of the equation, which is 581/0.07 = 8300.

So, your principle investment is $8300.

Good luck!
