Answer:

  y = -x -12

Step-by-step explanation:

The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...

  y -k = m(x -h) . . . . . . line of slope m through point (h, k)

  y -(-7) = -1(x -(-5))

  y = -x -5 -7 . . . . subtract 7, eliminate parentheses

  y = -x -12 . . . slope-intercept equation

Answer:

x = -1

Step-by-step explanation:

30 = 2.5(10)(-2x)  - you multiply by each

30 = 25 - 5x        - then pass 25 to the other side and subract

5x = - 5x               - then divide 5 / -5

x = -1                     - and you have the answer

Answer:

x= -1

Step-by-step explanation:

distribute 2.5 through the parenthese

30=25-5x

move variable to the left hand side an change its sign

5x+30 =25

move constant to the right hand side and change the sign

5x=25 -30

calculate the difference

5x= -5

divide both sides of the equation by 5

x= -1

Answer:

The 99% confidence interval of the  standard deviation of the pulse rates of men is  

       [tex][ 7.949 \  \ , \  14.387 ][/tex]

Step-by-step explanation:

From the question we are told that

  The  sample size is  n  =  40

  The mean is  [tex]\= x = 67.3 \ beats \ per \ minute[/tex]

  The standard deviation is  [tex]s = 10.3 \ beats \ per \ minute[/tex]

Generally the degree of freedom is mathematically represented as

     [tex]df = n- 1[/tex]

=>  [tex]df = 40- 1[/tex]

=>  [tex]df = 39[/tex]

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 99 ) \%[/tex]

=>   [tex]\alpha = 0.01[/tex]

Generally from the chi distribution table the critical value  of   at a degree of freedom of is  

   [tex]X^2 _{\frac{\alpha }{2} , 39} =  65.476[/tex]

Generally from the chi distribution table the critical value  of   at a degree of freedom of is  

   [tex]X^2 _{1- \frac{\alpha }{2} , 39} =  19.996[/tex]

Generally the 99% confidence interval of the standard deviation of the pulse rates of men is mathematically represented as

  [tex]s \sqrt{\frac{n- 1}{X^2_{1- \frac{\alpha }{2} , n-1} } }\  \ , \ s \sqrt{\frac{n- 1}{X^2_{\frac{\alpha }{2} , n-1} } }[/tex]

=>  [tex]10.3 \sqrt{\frac{40- 1}{65.476} }\  \ , \ 10.3 \sqrt{\frac{40- 1}{19.996} }[/tex]

=>  [tex][ 7.949 \  \ , \  14.387 ][/tex]

Answer: the vector orthogonal is  ( 0, 26, -13 )

Step-by-step explanation:

Given that;

P(2, 0, 2),  Q(−2, 1, 4), R(7, 2, 6)

PQ = Q - P = (−2, 1, 4) - (2, 0, 2) = (-4, 1, 2)

PR = R - P = (7, 2, 6)  - (2, 0, 2) = ( 5, 2, 4)

SO

orthogonal vector = PQ × PR

= ║ i    j    k

    -4   1   2          = i(1×4 - 2×2) + j(5×2 - (-4×4)) + k(-4×2 - 5×1) = 0i + 26j - 13k

     5   2   4  ║

= ( 0, 26, -13 )

Therefore the vector orthogonal is  ( 0, 26, -13 )

Answer:

a. What is the probability that Carl arrives first?

Probability that Carl arrives first is ¹/₃ = 33.33% since their arrival times is uniformly distributed. The same probability applies to Bob and Alice.

b. What is the probability that Carl will have to wait more than 10 minutes for one of the others to show up?

Assuming that Carl arrived on time, 1:10 PM, we must determine the probability that Alice or Bob arrive between 1:20 and 1:30 (half the remaining time)

P = [3 · (¹/₂ - ¹/₃)] · [3 · (¹/₂ - ¹/₃)] = (3 · ¹/₆) · (3 · ¹/₆) = ¹/₂ · ¹/₂ = ¹/₄ = 25% chance that either Alice or Bob arrive more than 10 minutes later

c. What is the probability that Carl will have to wait more than 10 minutes for both of the others to show up?

P = 1 - 25% = 75%

d. What is the probability that the person who arrives second will have to wait more than 5 minutes for the third person to show up?

I divided the 20 minutes by 5 to get ¹/₄:

P (|S - T| ≤ ¹/₄) = {[(x + ¹/₄)²] / 2} + (1 / 2x) + {[(⁵/₄ - x)²] / 2} = 0.09375 + 0.25 + 0.09375 = 0.4375 = 43.75%

Answer:

D= It is the total number of data points in the data set, which is also the sum of the row totals or the column totals.

Step-by-step explanation:

The number in the bottom right-hand corner of a two-way frequency table represents D. It is the total number of data points in the data set, which is also the sum of the row totals or the column totals.

When displaying frequencies or relative frequencies for two categorical variables, a two-way table is used. Columns indicate the second category, whereas rows represent the first.

The two-table displays frequencies for two categorical variables in terms of rows and columns.

The number in the bottom right-hand corner of a two-way frequency table represents the total number of data points in the data set, which is also the sum of the row totals or the column totals.

Answer:

46 is the answer

Step-by-step explanation:

Because:

a2 + c(2+b)

3(2) + 5(2+6)

6 + 5(8)

6 + 40

46

Answer:

49

Step-by-step explanation:

a² + c(2+b) = a² + 2c+bc

Expand first.

a² + 2c+bc = 3² + 2(5) + 6×5

Substitute a, b and c with actual values.

3² + 2(5) + 6×5 = 9 + 10 + 30

Evaluate.

9 + 10 + 30 = 49

4 6/7

Step-by-step explanation:

34/7

We finds out how many 7s are in 34

5 * 7 is 35, so it must be 4.

when 34 is divided by 7, the answer would be 4 and 6 remainders.

put the remainders back into the nominator part of the fraction.

so it's 4 6/7

Answer:

The amount of each person's profit is:

Mack

= $1160

Jason

= $725

Yuri

= $1015

Step-by-step explanation:

Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment Mack receives 2/5 of the profit, Jason Receives 1/4 of the profit, and Yuri receives the rest of the profitWhat is the amount of each person's profit?

Step 1

We calculate how much the profit is.

Mack, Jason, and Yuri invested a total of $14,500 in the stock market. After one year, they earned a profit equal to 1/5 of their investment

The profit = 1/5 of Investment

Hence = 1/5 × $14500

Profit = $2900

Step 2

We calculate the amount each of them receives.

Mack receives 2/5 of the profit,

= 2/5 × $2900

= $ 1160

Jason Receives 1/4 of the profit

= 1/4 × $2900

= $725

Yuri receives the rest of the profit

This is calculated as:

$2900 -($1160 + $725)

$2900 - $1885

= $1015

The amount of each person's profit is:

Mack

= $1160

Jason

= $725

Yuri

= $1015

Explanation:

FIRST DO

3(21) -7

3 × 21 = 63

63 - 7 = 56

Answer:

NOTE: NONE OF THE OPTIONS GIVEN IS CORRECT. THIS IS THE CORRECT ANSWER.

AB = EF, BC = FG, AC = EG

Step-by-step explanation:

According to the SSS Congruence statement, for ∆ABC to be congruent to ∆EFG, all the sides of ∆ABC must be congruent to all the corresponding sides of ∆EFG.

This means that:

AB must be congruent to EF

BC must be congruent to FG

AC must be congruent to EG

Therefore, additional information is needed to prove that triangles ABC and EFG are congruent by the SSS triangle congruence theorem are:

AB = EF, BC = FG, AC = EG
