Answer:

x > 3

Step-by-step explanation:

Answer:

x > 3

Step-by-step explanation:

Step 1:

8x - 6 > 12 + 2x         Equation

Step 2:

6x - 6 > 12        Subtract 2x on both sides

Step 3:

6x > 18          Add 6 on both sides

Step 4:

x > 18 ÷ 6      Divide 6 on both sides

Answer:

x > 3

Answer:

Clarence is 5 inches taller.

42-37=5

Answer:

Clarence is 5 inches taller.

Step-by-step explanation:

You are using subtraction by doing 42-37

42-37 cross out the 4 to be a 3, make the 2 a 12 and subtract 12-7=5

3-3 is 0 so it would be 5.

Answer:

[tex]\%Change = 58.33\%[/tex]

Step-by-step explanation:

Given

[tex]Initial = 12[/tex]

[tex]Final = 19[/tex]

Required

Determine the percentage change

Percentage change is calculated as thus:

[tex]\%Change = \frac{|FInal - Initial|}{Initial} * 100\%[/tex]

[tex]\%Change = \frac{|19 - 12|}{12} * 100\%[/tex]

[tex]\%Change = \frac{|7|}{12} * 100\%[/tex]

[tex]\%Change = \frac{7}{12} * 100\%[/tex]

[tex]\%Change = \frac{7* 100\%}{12}[/tex]

[tex]\%Change = \frac{700\%}{12}[/tex]

[tex]\%Change = 58.33\%[/tex]

Answer:

(1) 0 and 1

(2) Correct option D

Step-by-step explanation:

It is provided that pulse rates of women are normally distributed with a mean of 77.5 beats per minute and a standard deviation of 11.6 beats per minute.

Let X denote the pulse rates of women.

(1)

Let us consider a random variable, X that follows N (µ, σ²), then [tex]Z=\frac{X-\mu}{\sigma}[/tex], is a standard normal variate with mean, E (Z) = 0 and variance V (Z) = 1.

That is, Z follows N (0, 1).

In statistics, a standardized score is the number of standard deviations an observation or data point is from the mean.

Thus, z-scores are a type of standardized scores.

The values of the mean and standard deviation after converting all pulse rates of women to z scores are 0 and 1 respectively.

(2)

The z scores are numbers without units of measurement.

Answer:

5.5 gallons

Step-by-step explanation:

The answer is 5.5 gallons.

Number of containers = 14

Amount in each container = 1.5 liter

1 gallon = 3.8 liter

Total amount of tea in gallon

Total amount of tea in gallon = Number of containers × Amount in each container / 3.8

Total amount of tea in gallon = 14 × 1.5 / 3.8

Total amount of tea in gallon = 21 / 3.8

Total amount of tea in gallon = 5.5 liter (Approx.)

Answer:

I'm assuming A is -3/7 B is -0.4 and c is -1/5

Answer:

0.19146

0.066807

Step-by-step explanation:

Given that :

Mean (m) = 70

Standard deviation (s) = 10

a. Find the probability that a randomly selected high school senior will have a score between 70 and 75.

X ≤ 70 :

Using : z = (x - m) / s

Z = (70 - 70) / 10

Z = 0 / 10

Z = 0

P( Z < 70) = 0.500

X ≤ 75

z = (x - m) / s

Z = (75 - 70) / 10

Z = 5 / 10

Z = 0. 5

P(z < 0.5) = 0.69146

0.69146 - 0.5000

= 0.19146

b. Find the probability that a randomly selected high school senior will have a score higher than 85.

X ≥ 85

z = (x - m) / s

Z = (85 - 70) / 10

Z = 15 / 10

Z = 1.5

P(z > 1.5) = 0.066807 ( Z probability calculator)

Answer:

 [tex]P(K) = 0[/tex]

b

 [tex]P(Z) = 0[/tex]

c

[tex]P(W) = 0.1016[/tex]

d

 [tex]P(R) = 0.29[/tex]

Step-by-step explanation:

From the question we are told that

  The number of married people is  k = 15  

   The number of people that are not married is  u =  15

   The number of people selected is  e = 12

   The total number of people is n  =  30

Generally the number of ways of  selecting 12  people from the married people is mathematically represented as

        [tex]B = ^k C_e[/tex]

Here C stands for combination hence we will be making use of the combination functionality in our calculators

       [tex]B = ^{15} C_{12}[/tex]

=>   [tex]B = 455[/tex]

Generally the number of ways of  selecting 0  people from the not  married people is mathematically represented as

    [tex]A = ^u C_0[/tex]

=> [tex]A = ^{15} C_0[/tex]

=> [tex]A = 1[/tex]

Generally the number of ways of  selecting 12  people from the total number of  people is mathematically represented as

     [tex]D = ^{n} C_{12}[/tex]

=> [tex]D = ^{30} C_{12}[/tex]

=> [tex]D = 8.6493225 *10^{7}[/tex]

Generally the number of ways of selecting 12 people from the married people is equal to the number of ways of selecting 12 people from not married, also  the number of ways of selecting 0  people from the not married is equal to the number of ways of selecting 0 people from the married people,   all this is because the number of married people  is equal to the number of not married people

Generally the number of ways of selecting 8 people from the married people is  

      [tex]E = ^{k} C_{8}[/tex]

=>   [tex]E = ^{15} C_{8}[/tex]

=>   [tex]E =6435[/tex]

Generally the number of ways of selecting 4 people from the not  married people is  

       [tex]F = ^{u} C_{4}[/tex]

=>   [tex]F= ^{15} C_{4}[/tex]

=>   [tex]F=1365[/tex]

Generally the number of ways of selecting 6 people from the   married people is  

       [tex]G = ^{k} C_{6[/tex]

=>   [tex]G= ^{15} C_{6}[/tex]

=>   [tex]G=5005[/tex]

Generally the number of ways of electing 6 people from the married people is equal to the number of ways of selecting 6  people from the not married people

Generally the probability that the jury consists of all married people is mathematically represented as

        [tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(K) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(K) = 0.000005[/tex]

=>    [tex]P(K) = 0[/tex]

Generally the probability that the jury consists of all not married people  is mathematically represented as

        [tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(Z) = \frac{455 * 1 }{8.6493225 *10^{7}}[/tex]

=>     [tex]P(Z) = 0.000005[/tex]

=>    [tex]P(Z) = 0[/tex]

Generally the probability that the jury consists of 8 married and 4 that are not married is mathematically represented as

     [tex]P(W) = \frac{ E * F}{D}[/tex]

=>  [tex]P(W) = \frac{ 6435 * 1365}{8.6493225 *10^{7}}[/tex]

=>  [tex]P(W) = 0.1016[/tex]

Generally the probability that the jury consists of 6 married and 6 that are not married. is mathematically represented as

 [tex]P(R) = \frac{G * G}{D}[/tex]

  [tex]P(R) = \frac{5005 * 5005}{8.6493225 *10^{7}}[/tex]

=> [tex]P(R) = 0.29[/tex]

Answer:

b=4

Step-by-step explanation:

For this question we need to know the formula of slope that is m which is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where [tex](x_1,y_1) , (x_2,y_2)[/tex] are the points [tex](5,-8),(-1,b)[/tex] respectively

and hence we have the value of m= -2 which is the slope we simply plug in all the values.

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\-2=\frac{b-(-8)}{-1-5} \\\\-2=\frac{b+8}{-6} \\\\12=b+8\\12-8=b\\4=b[/tex]

So the value of b=4

Answer:

b is 4

Step-by-step explanation:

Several steps are required to find this answer. You need to use the information you are given as well as the formula y=mx+b. You are given the slope and one of the coordinates. Plug the information into the formula to find b, which is the constant.

The point given is (5,-8)

The slope given is -2

Plug the x and y into y=mx+b

-8=-2(5)+b

-8=-10+b

-8+10=b

b=2

Now that you have the full equation, y=-2x+2 , you can plug in the x-coordinate of the other coordinate to find the missing y-value.

y=-2(-1)+2

y=2+2

y=4

Therefore, the b you are solving for is 4.
