Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \sqrt{58} \: \: units}}}}}[/tex]

Step-by-step explanation:

Let the points be A and B

Let A ( 3 , -2 ) be ( x₁ , y₁ ) and B ( -4 , 1 ) be ( x₂ , y₂ )

Finding the distance between these points

[tex] \boxed{ \sf{distance = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }}[/tex]

[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 4 - 3)}^{2} + {(1 - ( - 2))}^{2} } }}[/tex]

[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 4 - 3)}^{2} + {(1 + 2)}^{2} } }}[/tex]

[tex] \dashrightarrow{ \sf{ \sqrt{ {( - 7)}^{2} + {(3)}^{2} } }}[/tex]

[tex] \dashrightarrow{ \sf{ \sqrt{49 + 9}}} [/tex]

Answer:

2.970600004839 × 10^5

Step-by-step explanation:

First, we add up these 2 numbers.

297,060 + 0.0004839 = 297060.0004839

Then, we convert that into scientific notation.

297060.0004839 = 2.970600004839 × 10^5

Finally, we check if it's right.

10^5 = 100000

2.970600004839 * 100000 = 297060.0004839

Answer:

The answer is 264

Step-by-step explanation:

We start with a ratio of inches to miles-        6:12

we see that it can be simplified to                  1:2

if we see that on the map it is 22in,             22:?

we got 1 to 22 by multiplying 1*22=22

do the same to the 12: 12*22=264

Answer:

14/3

Step-by-step explanation:

When 56 shares are evenly distributed between 12 people, each person gets equal number of shares.

The number of shares gotten by each person is the ratio of the total number of shares to the total number of people. It is given by the formula:

number of shares gotten by each person = total number of shares / total number of people

number of shares gotten by each person = 56 shares / 12 people

number of shares gotten by each person = 14/3 shares

[tex]g(-2)=6[/tex]

Step-by-step explanation:

Hi again!

So we have the equation:

[tex]g(x)=-4x-2[/tex]

To find g(-2), substitute -2 for x. Thus:

[tex]g(-2)=-4(-2)-2[/tex]

Multiply. -4 times -2 is positive 8:

[tex]g(-2)=8-2[/tex]

Subtract:

[tex]g(-2)=6[/tex]

Answer:

The best conclusion that can be made based on the data on the dot plot is:

The mean difference is not significant because the re-randomization show that it is within the range of what could happen by chance.

Step-by-step explanation:

Randomization is the standard used to compare the observational study and balance the factors between the treatment groups and eliminate the variables' influence. Some studies analyze that the treatment in the randomization calculates the appropriate number of the subjects as the treatment to memorize is 8.9, and the treatment for the B is 12.1 words.

The mean difference is not significant because the re-randomization shows that it is within the range of what could happen by chance.

The treatment group using technique A reported a mean of 8.9 words.

The treatment group using technique B reported a mean of 12.1 words.

After the data are re-randomized, the differences of means are shown in the dot plot.

The result is significant because the re-randomization show that it is outside the range. The best conclusion that can be made based on the data on the dot plot is:

The mean difference is not significant because the re-randomization show that it is within the range of what could happen by chance.

Answer:

The answer is actually

-The difference of the means is significant because the re-randomizations show that it is outside the range of what could happen by chance.

Answer:

We conclude that the true average lifetime is smaller than what is advertised.

Step-by-step explanation:

The complete question is: Light bulbs of a certain type are advertised as having an average lifetime of 800 hours. The price of these bulbs is very favorable, so a potential customer has decided to go ahead with a purchase arrangement unless it can be conclusively demonstrated that the true average lifetime is smaller than what is advertised. A random sample of 21 bulbs was selected, the lifetime of each bulb determined, and the appropriate hypotheses were tested using SPSS, resulting in the accompanying output.  

                         Sample Mean                         Sample Standard Deviation  

Lifetime               738.44                                                   38.30  

Test the appropriate hypothesis for this study (i.e., state the hypotheses, compute the test statistics, compute the p-value, and make a conclusion). What conclusion  would be appropriate for a significance level of 0.05?

We are given that Light bulbs of a certain type are advertised as having an average lifetime of 800 hours.

A potential customer has decided to go ahead with a purchase arrangement unless it can be conclusively demonstrated that the true average lifetime is smaller than what is advertised.

Let [tex]\mu[/tex] = true average lifetime of the light bulbs.

So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu \geq[/tex] 800 hours    {means that the true average lifetime is greater than or equal to what is advertised}

Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 800 hours    {means that the true average lifetime is smaller than what is advertised}

The test statistics that will be used here is One-sample t-test statistics because we don't know about the population standard deviation;

                               T.S.  =  [tex]\frac{\bar X-\mu}{\frac{s}{\sqrt{n} } }[/tex]  ~   [tex]t_n_-_1[/tex]

where, [tex]\bar X[/tex] = sample mean lifetime = 738.44 hours

             s = sample standard deviation = 38.30 hours

            n = sample of bulbs = 21

So, the test statistics =  [tex]\frac{738.44-800}{\frac{38.30}{\sqrt{21} } }[/tex]  ~  [tex]t_2_0[/tex]

                                     =  -7.36    

The value of t-test statistics is -7.36.

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

                 P-value = P([tex]t_2_0[/tex] < -7.36) = Less than 0.05% {from t-table}

Since the P-value of our test statistics is less than the level of significance of 0.05, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the true average lifetime is smaller than what is advertised.

Answer:

(x, y, z) → (18, 22, 9)

Step-by-step explanation:

sum of three numbers is 49

x + y + z = 49

second number is 5 less than three times the third number

y = 3z - 5

first number is twice amount of third number

x = 2z

set of equations

x + y + z = 49

y = 3z - 5

x = 2z

plug in 2nd and 3rd equation into first

(2z) + (3z - 5) + z = 49

combine like terms

2z + 3z - 5 + z = 49

6z - 5 = 49

add 5 to both sides

6z = 54

divide by 6

z = 9

plug z into 2nd and 3rd equations

y = 3(9) - 5

y = 27 - 5

y = 22

x = 2(9)

x = 18

check:

18 + 22 + 9 = 49

(x, y, z) → (18, 22, 9)

1 inch = 10 feet.

3 inches x 10 = 30 feet

5.5 inches x 10 = 55 feet
