Answer:

Jordan lives 18 miles away from the store

Step-by-step explanation:

Distance=speed × time

Where,

d= distance

s= speed

t= time

Total driving time takes half an hour

Distance=speed × time

time=Distance/speed

t=1.5

Speed 1=30 mph

Speed 2:=20 mph

t=d/s1 + d/s2

1.5=d/30 + d/20

1.5=20d + 30d / 600

1.5=50d/600

Cross product

1.5×600=50d

900=50d

Divide both sides by 50

900/50=d

18=d

Therefore,

d=18 miles

Jordan lives 18 miles away from the store

Answer:

(a) Null Hypothesis, [tex]H_0[/tex] : [tex]\sigma[/tex] = 10 beats per minute  

     Alternate Hypothesis, [tex]H_A[/tex] : [tex]\sigma\neq[/tex] 10 beats per minute  

(b) The value of chi-square test statistics is 35.704.

(c) P-value = 0.4360.

(d) We conclude that the pulse rates of men have a standard deviation equal to 10 beats per minute.

Step-by-step explanation:

We are given that a simple random sample of 36 men from a normally distributed population results in a standard deviation of 10.1 beats per minute.

If the range rule of thumb is applied to that normal​ range, the result is a standard deviation of 10 beats per minute.

Let [tex]\sigma[/tex] = population standard deviation for the pulse rates of men.

(a) So, Null Hypothesis, [tex]H_0[/tex] : [tex]\sigma[/tex] = 10 beats per minute      {means that the pulse rates of men have a standard deviation equal to 10 beats per minute}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\sigma\neq[/tex] 10 beats per minute      {means that the pulse rates of men have a standard deviation different from 10 beats per minute}

The test statistics that will be used here is One-sample chi-square test for standard deviation;

                             T.S.  =  [tex]\frac{(n-1)\times s^{2} }{\sigma^{2} }[/tex]  ~  [tex]\chi^{2}__n_-_1[/tex]  

where, s = sample standard deviation = 10.1 beats per minute

            n = sample of men = 36

So, the test statistics =  [tex]\frac{(36-1)\times 10.1^{2} }{10^{2} }[/tex]  ~ [tex]\chi^{2}__3_5[/tex]

                                   =  35.70  4

(b) The value of chi-square test statistics is 35.704.

(c) Also, the P-value of the test statistics is given by;

                    P-value = P([tex]\chi^{2}__3_5[/tex] > 35.704) = 0.4360

(d) Since the P-value of our test statistics is more than the level of significance as 0.4360 > 0.10, so we have insufficient evidence to reject our null hypothesis as the test statistics will not fall in the rejection region.

Therefore, we conclude that the pulse rates of men have a standard deviation equal to 10 beats per minute.

Answer:

1) The average rte of change = 6

2) The average rate of change over an interval is the ratio of the total change in the determinate variable or function (values of the output of the function) to the change in the indeterminate variable (values of the input of the function)

Step-by-step explanation:

1) The average of change of the function is found as follows;

At x = 0.75, y = -0.5, at x = 1.125, y = 1.75

Therefore, the average rate of change = (1.75 - (-0.5))/(1.125 - 0.75) = 6

2) The average rate of change over an interval on a graph or of a curve is found by dividing the difference between the y-coordinate values of the two points on the graph by the difference of the x-coordinate values of the two points.

Answer:

After factorizing the given polynomial we get 6x^2 (x+6)(x-2)

Step-by-step explanation:

Given Polynomial:  

6x^4+24x^3−72x^2

We need to completely factorize the polynomial.

Consider,

6x^4+24x^3−72x^2

GCF = 6x^2, By taking it common out

= 6x^2 (x^2+4x-12)

= 6x^2 (x^2+6x-2x-12)

= 6x^2 (x(x+6)-2(x+6))

= 6x^2 (x+6)(x-2)

Therefore, After factorizing the given polynomial we get 6x² ( x + 6 ) ( x - 2 )

Answer:

Yes

Step-by-step explanation:

Let the numbers be p q r such that p>q>r

So p + q + r = 3q

2q = p+ r

And q< p but q> c,

So by Solving this would give

q= (p+ r)/2

so q is the mean of p & r.

Since the only other number that fits is q,

Then q is the mean of the numbers p,q,r

As so q is also the median of this set

Thus proving that the mean is the same as the median.

Answer:

(5.4, 2.7)

Step-by-step explanation:

The coordinates of the point 7/10 of the way from A to B is given by the relation;

(x₁ + m×(x₂ - x₁), y₁ + m×(y₂ - y₁))

Where the coordinate of point A is (-3, -5) and the coordinates of the point B is (9, 6) we have;

x₁  = -3

m = 7/10

x₂ = 9

y₁ = -5

y₂ = 6

Substituting the values into the above equation gives;

-3 + 7/10 × (9 - (-3)), -5 + 7/10 × (6 - (-5)) = (5.4, 2.7)

The coordinate of the point P, 7/10 from A is (5.4, 2.7)

We check the length of the point from A to B to give;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex] =

[tex]l_{AB} = \sqrt{\left (6-(-5) \right )^{2}+\left (9-(-5) \right )^{2}} = \sqrt{265}[/tex]

the length of the point from A to B gives

[tex]l_{AB} = \sqrt{\left (2.7-(-5) \right )^{2}+\left (5.4-(-5) \right )^{2}} = \dfrac{7}{10} \times \sqrt{265}[/tex]

The coordinate of the point 7/10 of the way from A to B are (5.4, 2.7).

Answer:

[tex]\Huge \boxed{{f(-4)=-5}}[/tex]

Step-by-step explanation:

The function f(x) is given.

f(x) = 2x + 3

f(-4)

The input for the function f(x) is -4.

x is the input value.

x = -4

Replace x with -4.

f(-4) = 2(-4) + 3

Solve for the brackets.

f(-4) = -8 + 3

Evaluate.

f(-4) = -5

Answer: f(-4) = -5

Step-by-step explanation: Here we're given the function

f(x) = 2x + 3 and we're asked to find f(-4).

In other words, if we put a x into our function, we get a 2x + 3 out.

So what happens when we put a -4 into the function?

Well if we put a -4 into the function, that's f(-4), we get a 2(-4) + 3 out.

Now all we have to do is simplify on the right side.

2(-4) is -8 so we have -8 + 3 which is -5.

So f(-4) is -5.

Answer:

The equation that can be used to determine m, the number of minutes it will take the helicopter to reach the  hospital is [tex]172 \times (\frac{m}{60} ) = 80[/tex].

Step-by-step explanation:

We are given that a medical rescue helicopter is flying at an average speed of 172 miles per hour toward its base hospital. At 2:42 p.m., the helicopter is 80 miles from the hospital.

As we know that the Distance-Speed-Time formula is given by;

                           [tex]\text{Distance} = \text{Speed}\times \text{Time}[/tex]

Here, Distance = 80 miles

          Speed = 172 miles per hour

          Time = m (the number of minutes)

Firstly, as we can see that the speed is in miles per hour but the time is in minutes, so we will convert the time in hours, i,e;

           Time = [tex]\frac{\text{m}}{60} \text{ (in hours)}[/tex]

So,  [tex]\text{Distance} = \text{Speed}\times \text{Time}[/tex]

       [tex]80 = 172 \times (\frac{\text{m}}{60})[/tex]

       [tex]\text{m} = \frac{80 \times 60}{172}[/tex]

       m = 27.91 ≈ 28 minutes.

Hence, it will take 28 minutes for the helicopter to reach the  hospital.

Answer:

Width=7

Length=21

Step-by-step explanation:

Width=x

length=3x

x+x+3x+3x=56

8x=56

x=7

width = x = 7

length = 3x = 21

Answer:

Length = 21 and Width = 7

Step-by-step explanation:

Length (L)= 3x width (W)

L = 3W

Perimeter (P) = 56

Perimeter = 2L + 2W

56 = 2(3W) + 2W

56 = 6W + 2W

56 = 8W

W = 56/8

W = 7

L = 3W

L = 3(7)

L = 21

therefore Length = 21 and Width = 7

Answer:

C. 4

Step-by-step explanation:

This is just a common ratio.  These two triangles are alike, just that one is smaller than the other.  You can see that one of the sides of the big traingle is 10.  The same side of the smaller triangle is 5.  That means the big traingle's side is twice as big as the small circle's.  

10 divided by 5= 2

If the big triangle's side got divided by 2 to get the smaller triangle's side. So,  that means the other side of the big triangle, 8 is twice as big as the side on the smaller triangle, x.  

8 divided by 2= x

8 divided by 2= 4, so x= 4.

This is the ratio:

8:10 to x:5

As you can see the 10 got divided by 2 to get the 5.  So 8 must also get divided by 2, which equals 4.

Answer:

1. The equation that represent the distance (d) that a person can run in t hours is: d = 4t

2. The equation is: c = $0.98(20)

3. The equation is: L = 18(5)

Step-by-step explanation:

1. The variable d represents the distance over time, and t represents the hour in the equation so if you want to find the distance over time, you would say distance per hour. The per means to multiply, so every distance is equal to 4 miles per hour..

2. If the teacher wants to find out how much she will have to pay for 20 chocolate bar, she has to substitute 20 into the equation to replace b, which means bar. So the equation would be: total cost (c) = $0.98 × chocolate bars (b). Once substituted, the equation will be c = $0.98(20).

3. The problem said "mows 18 lawns per day" and "mow in 5 days", that means that you substitute 5 into the equation to replace the d in days, since you are multiplying 5 × 18.. Your new equation will be: L = 18(5), Total Lawns = 18 (lawns) per 5 (days).

Answer:

Step-by-step explanation:

Zeros are x-axis intercepts therefore y=0, so it's always (x, 0)

{For given function:

(x - 3)² - 16 = 0

(x - 3)² = 16

x - 3 = 4    or    x - 3 = -4

x = 7        or       x = -1

Zeros:  (7, 0) and (-1, 0)}

Answer - Blue; x > 2 and x ≤ -3

Ok so one most to the left shows an arrow going "lesser" and starting at -3. Since the dot covers -3, that means it is equal to or less than -3.

So the on most to the right starts at 2 and the arrow is point "greater"

The circle is hollow, meaning is does not include 2. So that means it's greater than 2.

Answer:

When x = 0, then y = -2

When y = 0, then x = 4

Step-by-step explanation:

We are given with the following equation;

x - 2y = 4

Now, we have to find the respective values of x and y for each value of x = 0 and y = 0.

Firstly, putting the value of x = 0;

x - 2y = 4

0 - 2y = 4

-2y = 4

y = [tex]\frac{4}{-2}[/tex]  = -2

This means that when x = 0, then y = -2.

Similarly, putting the value of y = 0;

x - 2y = 4

[tex]x-(2\times 0)=4[/tex]

x - 0 = 4

x = 4

This means that when y = 0, then x = 4.
