Answer:

yes, the slope is the same throughout the table

Step-by-step explanation:

Answer:

Yes, the graph shown is a proportional relationship.

Step-by-step explanation:

If you divide the distance (6) by the time (1) you get the same thing (6). Repeat for all the terms in the graphs. Since 6/1 is 6, 12/2 is 6, 18/3 is 6 and 24/4 is 6, The relationship is proportional.

Answer: Interior angles at Jamestown and Yorktown are 40° and 20°, respectively

Step-by-step explanation: Jamestown, Williamsburg and Yorktown form a triangle. The sum of the interior angles of a triangle is 180°.

Suppose interior angle at Yorktown is x. As Jamestown is twice the measure at Yorktown, it means this interior angle is 2x.

Then, the measures will be:

2x + x + 120 = 180

3x = 60

x = 20

Angle at Yorktown is 20°.

So, angle at Jamestown is

2x = 2.20 = 40°

The measures of the interior angles at Jamestown and Yorktown are 40° and 20°, respectively.

Answer:

3 pens

Step-by-step explanation:

Total expenditure (Price x Quantity) on pens & pencils = $30

Let pen quantity be = x , Let pencil quantity be = y

Given : Pen (x) price = 5 , Pencil (y) price = 1.5 , Pencils (y) = Pen (x) + 5

So, 5x + 1.5y = 30

5x + 1.5 (x + 5) = 30  → 5x + 1.5x + 7.5 = 30  → 6.5x + 7.5 = 30

6.5x = 30 - 7.5  → 6.5x = 22.5

x = 22.5 / 6.5 → x = 3.46  ≈ 3 pens

Answer:

the general form of the equation of the line will be:

[tex]y-x=2[/tex]

Step-by-step explanation:

Finding the slope:

Taking two points from the line as shown in figure

Finding the slope between (-2, 0) and (0, 2)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:0\right),\:\left(x_2,\:y_2\right)=\left(0,\:2\right)[/tex]

[tex]m=\frac{2-0}{0-\left(-2\right)}[/tex]

[tex]m=1[/tex]

Finding the y-intercept

We know that the y-intercept can be calculated by setting x=0

From the figure, it is clear that at x=0, y=2

Thus, the y-intercept is (0, 2)

We know that the slope-intercept form of the equation line is:

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

As we have already determined the slope = m = 1 and the y-intercept b=2.

Substituting the values in the slope-intercept form of the equation line

[tex]y=mx+b[/tex]

[tex]y=(1)x+2[/tex]

[tex]y=x+2[/tex]

Writing the equation in the standard form form

As we know that the equation in the standard form is

[tex]Ax+By=C[/tex]

where x and y are variables and A, B and C are constants

As we already know the equation in slope-intercept form

[tex]y=x+2[/tex]

so just simplify the equation to write in standard form

[tex]y-x=2[/tex]

Thus, the general form of the equation of the line will be:

[tex]y-x=2[/tex]

Answer: 5 and 12

Step-by-step explanation:

2 and 12 is not it   because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.

6 and 12 is not it because  12 can also be divided  by 6 meaning that the LCM of 6 and 12 is also 12.

3 and 12 is also the same,  12  can be divided by 3 so their LCM will be 12.

With 5 and 12, 12 is not divisible by 5 so  you will have to find the multiples of 5 and 12 and it will eventually be 60.

Multiples of 5:  5, 10,15,20,25,30,35,40,45,50,55,60,65

Multiples of 12:  12, 24, 36, 48, 60, 72  

As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.

Answer:

It's 5 and 12

Step-by-step explanation:

Answer:

15.4%

Step-by-step explanation:

Calculate the volume of both containers.

The volume (V) of a cylinder is calculated as

V = πr²h ( r is the radius and h the height )

[tex]V_{A}[/tex] = π × 10² × 11 = 1100π ft³

[tex]V_{B}[/tex] = π × 7² × 19 = 931π ft³

Subtract volume of B from volume of A to find quantity left in A

quantity left in A = 1100π - 931π = 169π ft³

To calculate the percentage left in A after B has been filled

[tex]\frac{left}{full}[/tex] × 100%

= [tex]\frac{169\pi }{1100\pi }[/tex] × 100%

= [tex]\frac{169}{1100}[/tex] × 100%

= 15.4% ( to the nearest tenth )

Answer:

What do you but in the chart? Also, part 2 is 72

Step-by-step explanation:

Answer:

72

Step-by-step explanation:

If each t-shirt costs 3.6 dollars then you would have to multiply 3.6 by 20 shirts which will equal to 72. So Charlie has to pay 72 dollars for 20 shirts.

Answer:

6%

Step-by-step explanation:

Estimated distance = 80 miles

Actual distance covered = 75.5 miles

We need to find the percent error of the cyclist's estimate. Its formula is given by :

[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]

Put all the values,

[tex]\%=\dfrac{80-75.5}{75.5}\times 100\\\\=5.96\%[/tex]

or

= 6%

So, the percentage error is 6%.

Answer:

Time= 4 years

Step-by-step explanation:

Giving the following information:

Principal (P)= $12,000

Interest rate (r)= 10% = 0.10

Interest earned (I)= $4,800

To calculate the time required to gain $4,800 interest, we need to use the following formula:

T= I / (P*r)

T= 4,800/(12,000*0.1)

T= 4 years

Answer:

Hope its work for you

Step-by-step explanation:

As we know that,

As given values

take,   (X1,Y1)=(-7,-4)

           (X2-Y2)=(8,8)

hence   X1=-7  ,  Y1= -4   ,  X2=8  , Y2= 8

putt the values in the above equation of slope we get ,

m=(8-(-4))/(8-(-7)

Answer:

0.8

Step-by-step explanation:

Slope=(y2-y1) (8--4) (12)

(x2-x1)= (8--7)= (15)= 0.8

Answer:

 y = − 2 x

Step-by-step Explanation:

Y + 2 = − 2 ⋅ ( − 1 )  Write in   y = m x + b  form.

I hope I helped!

Answer:

y = -2x + 8

Step-by-step explanation:

For this problem we need to consider that the equation of a line perpendicular to another line will have a "negative reciprocal" slope so that when they cross, it forms a 90-degree angle, hence perpendicular.  Additionally, we will need to use the point-slope form and re-write it into the slope-intercept form to incorporate (2,4) into our equation.  With these things in mind, let's do that.

y = (1/2)x + (1/2)

We want a "negative reciprocal" so:

y = -2x + (1/2)

Since -2 is the "negative reciprocal" of 1/2.

And now we want to use the point-slope form to incorporate (2,4)

y - y0 = -2 ( x - x0 )

Where, y0 = 4 and x0 = 2.

y - y0 = -2 ( x - x0 )

y - 4 = -2 ( x - 2 )

y - 4 = -2x + 4

y = -2x + 8

So, the equation that is perpendicular to y = (1/2)x + (1/2) and includes the point (2,4) is y = -2x + 8.

Cheers.

Answer:

(a) Explained below.

(b) The 99% confidence interval for the difference between proportions is (-0.00094, 0.00494).

Step-by-step explanation:

The information provided is:

n (Men who finished the marathon) = 25,221

n (Women who finished the marathon) = 12,883

Compute the proportion of men and women who finished the marathon as follows:

[tex]\hat p_{1}=\frac{25221}{25221 +253}=0.99\\\\\hat p_{2}=\frac{12883 }{12883+163}=0.988[/tex]

The combined proportion is:

[tex]\hat P=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}\\\\=\frac{25221+12883}{38520}\\\\=0.989[/tex]

(a)

The hypothesis is:

H₀: The rate of those who finish the marathon is the same for men and women, i.e. p₁ - p₂ = 0.

Hₐ: The rate of those who finish the marathon is not same for men and women, i.e. p₁ - p₂ ≠ 0.

Compute the test statistic as follows:

[tex]Z=\frac{\hat p_{1}-\hat p_{2}}{\sqrt{\hat P(1-\hat P)\cdot [\frac{1}{n_{1}}+\frac{1}{n_{2}}]}}[/tex]

   [tex]=\frac{0.99-0.988}{\sqrt{0.989(1-0.989)\times[\frac{1}{25474}+\frac{1}{13046}]}}\\\\=1.78[/tex]

Compute the p-value as follows:

[tex]p-value=2\times P(Z>1.78)\\\\=2\times 0.03754\\\\=0.07508\\\\\approx 0.075[/tex]

The p-value of the test is more than the significance level. The null hypothesis was failed to be rejected.

Thus, concluding that the rate of those who finish is the same for men and women.

(b)

Compute the 99% confidence interval for the difference between proportions as follows:

The critical value of z for 99% confidence level is 2.58.

[tex]CI=(\hat p_{1}-\hat p_{2})\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p_{1}(1-\hat p_{1})}{n_{1}}+\frac{\hat p_{2}(1-\hat p_{2})}{n_{2}}}[/tex]

     [tex]=(0.99-0.988)\pm 2.58\times\sqrt{\frac{0.99(1-0.99)}{25474}+\frac{0.988(1-0.988)}{13046}}\\\\=0.002\pm 0.00294\\\\=(-0.00094, 0.00494)\\\\[/tex]

Thu, the 99% confidence interval for the difference between proportions is (-0.00094, 0.00494).

add 1 to both sides

= 13x=91

divide both sides by 13

= x=7
