Answer:

Yes

Step-by-step explanation:

cousin

1/20 inches

Hi there !

cousin

21 4/5 = (21×5+4)/5 = 109/5

friend

21 3/4 = (21×4+3)/4 = 78/4

lcm(4 ; 5) = 20

⁴⁾109/5 = 436/20 (cousin)

⁵⁾87/4 = 435/20 (friend)

436/20 > 435/20

cousin > friend

436/20 - 435/20 = 1/20 inches longer (cousin)

Good luck !

Answer : The area of the shaded portion is 33.72 yd².

Step-by-step explanation :

Given:

Length of the box = 10 yd

Width of the box = 4 yd

Area of the shaded portion = Area of rectangular box - Area of half circle

First we have to calculate the area of rectangular box.

Area of rectangular box = Length of the box × Width of the box

Area of rectangular box = 10 yd × 4 yd

Area of rectangular box = 40 yd²

Now we have to calculate the area of half circle.

As we know that:

Area of circle = π × r²

where,

r = radius of circle

Area of half circle = [tex]\frac{\pi \times r^2}{2}[/tex]

Radius of circle = [tex]\frac{4yd}{2}=2yd[/tex]

Area of half circle = [tex]\frac{3.14 \times (2yd)^2}{2}[/tex]

Area of half circle = 6.28 yd²

Now we have to calculate the area of the shaded portion.

Area of the shaded portion = Area of rectangular box - Area of half circle

Area of the shaded portion =  40 yd² - 6.28 yd²

Area of the shaded portion =  33.72 yd²

Therefore, the area of the shaded portion is 33.72 yd².

Answer:

-6u +9 w +12

Step-by-step explanation:

Answer:

The answer is 140

Step-by-step explanation:

We are asked to find the stopping distance, in feet, when x=40 miles per hour. We will substitute this into the polynomial expression 0.06x2+1.1x, and then simplify using the order of operations.

0.06(40)2+1.1(40)=96+44=140

When driving at x=40 miles per hour, the stopping distance is 140ft.

Answer:

y = x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

- 4x + 4y = 16 ( add 4x to both sides )

4y = 4x + 16 ( divide all terms by 4 )

y = x + 4 ← in slope- intercept form

Answer:

x = 1/8

Answer:

A. 10,000

B. 1,000,000

C. 10,000,000,000

D. 1,000,000,000,000

Step-by-step explanation:

10,000/ 10∧4 = 1

1,000,000/ 10∧6 = 1

10,000,000,000/ 10∧10 = 1

1,000,000,000,000/ 10∧12 = 1

Answer:

The decision rule is

Reject the null hypothesis

The conclusion is  

There is sufficient evidence to conclude that the data support the hypothesis that the mean depression score for ALS caregivers is significantly higher than the cutoff score for depression of 25

dependent/outcome variable

Generally the dependent variable is  Beck Depression Inventory (BDI) scores because the score are dependent on the ALS caregivers

Step-by-step explanation:

From the question we are told that

  The sample size is  n = 20

  The population mean is  [tex]\mu  =  25[/tex]

   The sample mean is  [tex]\= x  = 28[/tex]

  The standard deviation is  [tex] s  =  3.0[/tex]

  The null hypothesis is [tex]H_o  :  \mu  =  25[/tex]

  The alternative hypothesis is  [tex]H_a  :  \mu  >  25[/tex]

  Generally the test statistics is mathematically represented as

     [tex]z = \frac{\= x - \mu }{ \frac{s}{\sqrt{n} } }[/tex]

=>  [tex]z= \frac{ 28 -25 }{ \frac{3.0}{\sqrt{20 } } }[/tex]

=>  [tex]z=  4.47[/tex]

 Generally the probability of  z from the z- table is

   [tex]p-value  =  P(Z >  4.47) =  0.000[/tex]

From the values obtained we see that  [tex]p-value  <  \alpha[/tex] hence

The decision rule is

Reject the null hypothesis

The conclusion is  

There is sufficient evidence to conclude that the data support the hypothesis that the mean depression score for ALS caregivers is significantly higher than the cutoff score for depression of 25

Generally the dependent variable is  Beck Depression Inventory (BDI) scores because the score are dependent on the ALS caregivers

Answer: Put 5 in each tank

Step-by-step explanation:

Answer:

looks like the parallel lines are "l" and "n"

Step-by-step explanation:

when two lines are parallel, they should be across from each other going the same way. For example: / / , or \ \  sometimes even on top of each other. It can't be line "m" because it seems a little slanted. Parallel lines have to be the same length and same size. It can't be line "t" because the line is going in a different direction.

Answer:

The 95% confidence interval for the difference in population proportions is (0.001, 0.079).

Step-by-step explanation:

The (1 - α)% confidence interval for the difference in population proportions is:

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

The information provided is as follows:

[tex]\hat p_{1}=0.95\\\hat p_{2}=0.91\\n_{1}=300\\n_{2}=350\\[/tex]

The critical value of z for 95% confidence level is 1.96.

Compute the 95% confidence interval for the difference in population proportions as follows:

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

     [tex]=(0.95-0.91)\pm 1.96\times\sqrt{\frac{0.95(1-0.95)}{300}+\frac{0.91(1-0.91)}{350}}\\\\=0.04\pm 0.0388\\\\=(0.0012, 0.0788)\\\\\approx (0.001, 0.079)[/tex]

Thus, the 95% confidence interval for the difference in population proportions is (0.001, 0.079).

Answer:

x-intercept: (-40, 0)

y-intercept: (0, 15)

Step-by-step explanation:

The x-intercept is the value of x when y = 0. By looking at the graph, you can tell when y = 0, x = - 40. The x-intercept is the point that crosses the x-axis.

The y-intercept is the value of y when x = 0. By looking at the graph, you can tell y = 15 when x =0. The y-intercept is the point that crosses the y-axis.

answer: HJ is -13.

Using line segments concepts, it is found that:

-------------------------------

[tex]HK = HJ + JK[/tex]

-------------------------------

We are given that:

Thus, replacing into the equation, it is possible to solve for x.

-------------------------------

[tex]HK = HJ + JK[/tex]

[tex]33 = 3x - 4 + 2x + 7[/tex]

[tex]5x + 3 = 33[/tex]

[tex]5x = 30[/tex]

[tex]x = \frac{30}{5}[/tex]

[tex]x = 6[/tex]

The value of x is 6.

-------------------------------

The length of line segment HJ is:

[tex]HJ = 3x - 4 = 3(6) - 4 = 18 - 4 = 14[/tex]

Answer:

A

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 2 and (a, b) = (3, 1 ), thus

y - 1 = 2(x - 3) → A

The equation of the line with slope 2 that passes through (3, 1) is [tex](y-1)=2(x-3)[/tex] and this can be determined by using the one-point slope form.

Given :

The line with slope 2 that passes through (3, 1).

The following steps can be used in order to determine the equation of the line with slope 2 that passes through (3, 1):

Step 1 - The one-point form of the line can be used in order to determine the equation of the line with slope 2 that passes through (3, 1).

Step 2 - The equation that shows one-point form is given below:

[tex](y-y_1)=m(x-x_1)[/tex]

where m is the slope and [tex](x_1,y_1)[/tex] is the point on the line.

Step 3 - Substitute the values of the known terms in the above equation.

[tex](y-1)=2(x-3)[/tex]

Therefore, the correct option is A).
