Answer:

The equation of the line is:

y - 5 = 3/2 (x - 2)

Transforming the line into the slope intercept form:

y = 3x/2 - 3 + 5

y = 3x/2 + 2

The slope is 3/2 and the y-intercept is 2.

Plotting this on the graph can be done using these steps:

Locate the point (0,2) on the graph.

From (0,2), count 3 units up and 2 units to the left and indicate that point.

Finally, connect the two points and extend the line.

Answer:

Step-by-step explanation:

Length of the room = 12 4/5 ft = 12.8 ft

Scale is 0.25 inches = 1 ft.

This means that every 1ft is shown as 1/4 inch on the map.

To find what 12 4/5ft on the map, you would multiply 12.8 by 0.25.

12.8 x 0.25 = 3.2 inches

Step-by-step explanation:

The given ratio specifies the number of apples to be found in the basket

for a given number of oranges.

Correct response:

The given ratio of apples to oranges in the basket of fruits = 2:7

The number of oranges = 21 oranges

Required:

The number of apples in the basket.

Solution:

The given ratio can be expressed as follows;

Which gives;

[tex]\dfrac{Number \ of \ apples}{21} = \dfrac{2}{7} [/tex]

7 × (Number of apples) = 2 × 21

[tex]Number \ of \ apples = \dfrac{2 \times 21}{7} = 6[/tex]

Answer:

y=ax+9−2a (i think )

Step-by-step explanation:

A straight line is represented by a linear function

The equation of line a is: [tex]\mathbf{y = 2x +5}[/tex]

The points are given as:

(x1,y1) = (-2,1)

(x2,y2) = (2,9)

Calculate the slope (m)

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

So, we have:

[tex]\mathbf{m = \frac{9-1}{2--2}}[/tex]

[tex]\mathbf{m = \frac{8}{4}}[/tex]

[tex]\mathbf{m = 2}[/tex]

The equation in slope intercept form is:

[tex]\mathbf{y = m(x - x_1) + y_1}[/tex]

So, we have:

[tex]\mathbf{y = 2(x +2) + 1}[/tex]

[tex]\mathbf{y = 2x +4 + 1}[/tex]

[tex]\mathbf{y = 2x +5}[/tex]

Hence, the equation of line a is: [tex]\mathbf{y = 2x +5}[/tex]

Answer:

R1:   Given

R2:   Subtraction Property of Equality

R3:   Distribute Property

R4:   Addition Property of Equality

R5:   Division Property of Equality

Write a paragraph proof for the following conjecture: m∠1 + m∠2 = m∠4

Prove: m∠3 + m∠1 + m∠2 = 180°

Given: ∠1 + ∠2 = ∠ 4

∠4 + ∠3 must be 180° because they are supplementary

If ∠4 + ∠3 is 180, and ∠1 + ∠2 = ∠4, you can substitute ∠4 in the first equation for ∠1 + ∠2.

Hence, we arrive at the answer ∠1 + ∠2 + ∠3 = 180.

Answer:

H

Step-by-step explanation:

Answer:

Explained below.

Step-by-step explanation:

The claim made by an expert is that driving conditions are dangerous if the variance of speeds exceeds 75 (mph)².

(1)

The hypothesis for both the test can be defined as:

H₀: The variance of speeds does not exceeds 75 (mph)², i.e. σ² ≤ 75.

Hₐ: The variance of speeds exceeds 75 (mph)², i.e. σ² > 75.

(2)

A Chi-square test will be used to perform the test.

The significance level of the test is, α = 0.05.

The degrees of freedom of the test is,

df = n - 1 = 55 - 1 = 54

Compute the critical value as follows:

[tex]\chi^{2}_{\alpha, (n-1)}=\chi^{2}_{0.05, 54}=72.153[/tex]

Decision rule:

If the test statistic value is more than the critical value then the null hypothesis will be rejected and vice-versa.

(3)

Compute the test statistic as follows:

[tex]\chi^{2}=\frac{(n-1)\times s^{2}}{\sigma^{2}}[/tex]

    [tex]=\frac{(55-1)\times 94.7}{75}\\\\=68.184[/tex]

The test statistic value is, 68.184.

Decision:

[tex]cal.\chi^{2}=68.184<\chi^{2}_{0.05,54}=72.153[/tex]

The null hypothesis will not be rejected at 5% level of significance.

Conclusion:

The variance of speeds does not exceeds 75 (mph)². Thus, concluding that driving conditions are not dangerous on this highway.
