Answer:

Option A: 3.59% is the correct answer

Step-by-step explanation:

Z-score is used to calculate the probabilities when mean and standard deviation is given.

Given

Mean = μ = 21

SD = σ = 5

We have to find the probability of selling 12 or less water heaters so our x value is 12

x = 12

The z-score of a value is calculated as:

z-score = (x-μ)/σ

Putting the values

[tex]z-score=\frac{12-21}{5} \\=\frac{-9}{5}\\=-1.8[/tex]

Now z-score table will be used to calculate the probability for z= -1.8

So we will go for the row with -1.8 and column 0, which gives us: 0.03593

As we have to calculate the probability in percentage

[tex]=0.03593*100\\= 3.593\%[/tex]

Hence,

Option A: 3.59% is the correct answer

Answer:

Continuous

Step-by-step explanation:

Answer:

x = 9 and y = 1

Step-by-step explanation:

Here,

x = 10 - y and y = x - 8 is given

then, name the equation

x = 10 - y ...(1)

y = x - 8 ...(2)

Now, put the value of x in equation (2) we get

y = x - 8

y = (10 - y) - 8

y = 10 - y - 8

y + y = 10 - 8

2y = 2

y = 2÷2

y = 1

Here, we get the value of y = 1

Now, we put the value of y in equation (1) we get

x = 10 - y

x = 10 - (1)

x = 10 - 1

x = 9

x = 10 - y

9 = 10 - 1

9 = 9

Hence, LHS = RHS

Answer:b

Step-by-step explanation:

Explanation:

Replace x with 4. Then use PEMDAS to simplify fully.

[tex]y = (14+x) \div 2\\\\y = (14+4) \div 2\\\\y = 18 \div 2\\\\y = 9\\\\[/tex]

When using PEMDAS, we evaluate the stuff in the parenthesis first. Afterward we divide.

Step-by-step explanation:

Step 1: Factor both the numerator and the denominator.

Step 2: Write as one fraction.

Step 3: Simplify the rational expression.

Step 4: Multiply any remaining factors in the numerator and/or denominator.

Step 1: Factor both the numerator and the denominator.

Step 2: Write as one fraction

Answer:

Step-by-step explanation:

perimeter of semicircle = 1/2 π d

                                       = 1/2 π (6)

                                       = 9.425 x 4 semicircles

                                       = 37.7

Note: you did not correctly enter the right expression. After a little research, I am able to find the correct expression which is as follows:

4y+9/7 when y = 8

Therefore, I am solving your query based on evaluating the expression

4y+9/7 when y = 8

Answer:

we conclude that after substituting, the first step is to 'Multiply 8 by 4'.

Step-by-step explanation:

Given the expression

4y+9/7

As we have to evaluate the given expression for the y=8

substituting y=8 in the expression

4y+9/7

= 4(8)+9/7

According to PEMDAS rule, we first need to do multiplication

Thus, the first step must have to be multiplying 4 and 8.

= 32 + 9/7

= 233/7

Therefore, we conclude that after substituting, the first step is to 'Multiply 8 by 4'.

Answer:

Step-by-step explanation:

if DEF is congruent to JKL, this means that the sides of JKL are all equal to that of DEF.

Hence we can say;

DE = JK

EF = KL

DF = JL

Given

DE = 18,

EF =23,

DF = 9x-23,

JL = 7x-11

JK = 3y-21,

Required

Values of  x and y

Since DE = JK;

18 = 3y-21

18+21 = 3y

39 = 3y

y = 39/3

y = 13

Also, DF = JL

9x-23 = 7x-11

collect like terms

9x - 7x = -11+23

2x = 12

x = 12/2

x = 6

Hence the value of x is 6 and y is 13

Given: [tex]DE=18[/tex],[tex]EF=23,DF=9x-23,JL=7x-11,[/tex] and[tex]JK=3y-21.[/tex]

As [tex]\Delta[/tex][tex]DE[/tex][tex]F[/tex]  [tex]\cong[/tex]  [tex]\Delta JKL[/tex]

[tex]\Rightarrow DE=JK \ ; EF=KL \ and \ DF=JL[/tex]

[tex]\Rightarrow 18=3y-21 \ ; 23=KL \ and \ 9x-23=7x-11[/tex]

     [tex]y=13[/tex]         ; [tex]KL=23[/tex]    and        [tex]x=6[/tex]

Therefore, [tex]x=6[/tex]  and [tex]y=13[/tex]

Answer:

[tex]Probability = \frac{13}{15}[/tex]

Step-by-step explanation:

Given

Ticket Numbers = 1 to 60

Required

Determine the probability of not selecting multiples of 7

First, we need to list out the multiples of 7 in this range:

[tex]Multiple = 7,14,21,28,35,42,49,56[/tex]

These are 8 in numbers. So, there are 8 multiples

Next, is that we determine the number of non multiples of 7. This s calculated as:

[tex]Non\ Multiples = 60 - 8[/tex]

[tex]Non\ Multiples = 52[/tex]

The required probability is then calculated as:

[tex]Probability = \frac{Non\ Multiples}{Total}[/tex]

[tex]Probability = \frac{52}{60}[/tex]

[tex]Probability = \frac{13}{15}[/tex]

Answer:

Step-by-step explanation:

There are 8 numbers between 24 and 31, inclusive. So the probability of getting a number in that range is 885. Therefore, by the complement rule, the probability of not getting one of these numbers is

[tex]1-(8/85)= 85- 8 /85=77/ 85[/tex]

Answer:

Step-by-step explanation:

Step one

given the coordinates

ABCD with vertices A(-2,-2), B(-1,3), C(5, 3), and D(4, -2)

AB=(-2,-2),(-1,3)

BC=(-1,3), (5, 3)

CD=(5, 3),(4, -2)

DA=(4, -2),(-2,-2)

The distance between points AB=

[tex]AB= \sqrt (x_2-x_1)^2+(y_2-y_1)^2[/tex]

[tex]AB= \sqrt (-1+2)^2+(3+2)^2\\\\AB= \sqrt 1^2+(5)^2\\\\AB= \sqrt26\\\\AB=5.1[/tex]

The distance between points BC=

[tex]BC= \sqrt (5+1)^2+(3-3)^2\\\\BC= \sqrt 6^2+(0)^2\\\\BC= \sqrt36\\\\BC=6[/tex]

The distance between points CD

[tex]CD= \sqrt (4-5)^2+(-2-3)^2\\\\CD= \sqrt -1^2+(-5)^2\\\\CD= \sqrt26\\\\CD=5.1[/tex]

The distance between points DA

[tex]DA= \sqrt (4+2)^2+(-2+2)^2\\\\DA= \sqrt 6^2+(0)^2\\\\DA= \sqrt36\\\\DA=6[/tex]

Hence the perimeter = 5.1+6+5.1+6

Answer:

44.125 inches

Step-by-step explanation:

Given that:

Length of picture = 32 1/2 inches

Length of wall = 120 3/4 inches

Hence, to center picture horizontally ;

Distance from the edge of the wall in which the picture should be placed :

(Length of wall - length of picture) / 2

(120 3/4 - 32 1/2) / 2

(483/4 - 65/2) / 2

Take the L. C. M of 4 and 2 = 4

((483 - 130) / 4) ÷ 2

(353 / 4) ÷ 2

(353 / 4) * (1 / 2)

= 353 / 8

= 44 1/8

= 44 1/8

= 44.125 inches

The space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.

The wall that Jon wants to hang the picture has been sketched in the diagram attached below (see attachment).

Given the following:

Therefore, the following equation can be derived as follows:

[tex]2x + 32.5 = 120.75[/tex]

[tex]2x = 120.75 - 32.5 \\\\2x = 88.25\\\\x = \frac{88.25}{2} \\\\\mathbf{x = 44.125 $ inches}[/tex]

Therefore, the space that will be left in each side of the picture from the edge of the wall if Jon is to hang the picture at the center of the wall horizontally is: 44.125 inches.
