I will not be surprised because the probability that fewer than half covered their mouth when​ sneezing is less than 0.5

Step-by-step explanation:

From the question we are told that

   The probability a randomly selected individual will not cover his or her mouth when sneezing is [tex]p = 0.267[/tex]

    The probability a randomly selected individual will cover his or her mouth when sneezing is

                   [tex]q = 1 -p[/tex]

                   [tex]q = 1 -0.267[/tex]

                    [tex]q = 0.733[/tex]

Generally the probability that among 12 randomly observed individuals exactly 8 do not cover their mouth when​ sneezing is mathematically represented as

        [tex]P(X =  8 ) =  \left 12 } \atop {}} \right. C_8 *  p^8 *  q^{12-8}[/tex]

        [tex]P(X =  8 ) = 495 *  (0.267)^8 *  (0.733)^{12-8}[/tex]

        [tex]P(X =  8 ) =  0.0037[/tex]

Generally the probability that among 12 randomly observed individuals fewer than 5 do not cover their mouth when​ sneezing is mathematically represented as

       [tex]P(X <  5 ) =  P[ P(X = 0) + \cdots + P(X =  4)][/tex]

=>        [tex]P(X <  5) = \left 12 } \atop {}} \right. C_0 *  (0.267)^0 * (0.733)^{(12- 0) }+\cdots +  \left 12 } \atop {}} \right. C_4 *  (0.267)^0 * (0.733)^{(12- 4) }[/tex]

=>     [tex]P(X < 5) =  0.805[/tex]

Give that half of  12 is  6 then

The probability that fewer than half covered their mouth when​ sneezing is mathematically represented as

      [tex]P(X > 6) =  1 -  P( X \le 6 )[/tex]

  => [tex]P(X > 6)  =  1 -  [P(X = 0 ) +\cdots+P(X = 6) ][/tex]

 => [tex]P(X > 6) = 1 -  [\left 12 } \atop {}} \right. C_0 *(0.267)^0 *  (0.733)^{12 - 0 } +\cdots + \left 12 } \atop {}} \right. C_6 * (0.267)^6 *  (0.733)^{12-6}][/tex]

=>    [tex]P(X > 6)   =  0.0206[/tex]

Answer: 2.40

Step-by-step explanation: 2.4 meters 10x.24=2.40

On the vertical number line, negative numbers are to the bottom of 0. Therefore, -1/4 will go one unit down from 0.

On the horizontal number line, negative numbers are to the left of 0. Therefore, -1/4 will go to the left one unit.

Answer:

x = -2

Step-by-step explanation:

3{-x + 2x + 1} = x - 1

-3x + 6x + 3 = x - 1

3x + 3 = x - 1

2x = -4

x = -2

Answer:

x=440 gaL 90 % Antifreeze II

Step-by-step explanation:

In the problem, there are two types of antifreeze

antifreeeze I and

antifreeze II

antifreeze I 25 ----80 gal

Antifreeze II 90 ----- x gal

Total 80 ---------------- (80 + x ) gal

(25*80)+(90*x)=80(80+x)

2000+90x=6400+80x

90x-80x=6400-2000

10x=4400

divide both sides by 10 we have

x= 440

x=440 gaL 90 % Antifreeze II

Answer:

m = - 2n + 5

Step-by-step explanation:

Given the equation:

m+1=-2n+6

Rearrange the equation so that n is the independent variable

The independent variable is the predictor variable, Hence causes a change in the value of predicted variable obtained.

m+1=-2n+6

m = - 2n + 6 - 1

m = - 2n + 5

m = - 2n + 5

The general form of a regression equation:

y = ax + b

Where y = dependent variable

x = independent variable ; a = Coefficient of slope ; b = intercept

Hence, the equation : m = - 2n + 5

Step-by-step explanation:

3x+4=7x-4

add 7x to each side of equation 4x+3x+-7x=-4x+7x+-7x

combine like terms 7x+-7x=0

4+ -4x =-4 +0

4+-4x= -4

add -4 to each side of equation 4+ -4 +-4x=-4+-4

combine like terms -4 +4=0

0+ -4x = -4+ -4

combine like terms -4+-4=-8

-4x =-8

divide each side by-4

x=2

simplifying

x = 2

Answer:

33 additional goals

Step-by-step explanation:

59+g is greater than or equal to 92 subtract 59 from both sides leaving the answer g is greater than or equal to 33

The hockey player would have to score:

In order the match the record, the hockey player needs to score a certain number of goals that will take them to the record of 92. That number is:

= 92 - 59

= 33 goals

If they however want to break the record, the need to score more than 92 goals. The least number of goals they can score to do so is:

= Number of goals to match record + 1

= 33 + 1

= 34 goals

In conclusion, the player would have to score 33 goals to match the NHL record but 34 to break it.

Answer:

b. 10 - 61

Step-by-step explanation:

10 + 61 is 71

We need to change the addition sign to subtraction.

10 -  61= -51

We need to find an equation that is equal to -51.

a. -10 +61

That equals 51, which is not 71, which means it is not letter a.

b. 10 - 61

That equals -51, which is not 71, which means it is not letter b.

c. -10 - 61

That equals -71, which is not 71, which means it is not letter c.

d. 6- 107

That equals -101, which is not 71, which means it is not letter d.
