Answer:

C. 82/3 is the correct answer

Step-by-step explanation:

A. √27 is incorrect because it is equal to 5.2

B. 5^2 is incorrect because it is equal to 25

D. √602 is incorrect because it is equal to 24.5

soooo...

The only correct answer is C. 82/3 because it equals 27 1/3 or 27.3

Answer: 1/6.

Step-by-step explanation:

The possible outcomes of Bob are {1, 2, 3, 4}

The possible outcomes of Alice are {1, 2, 3, 4, 5, 6}

Notice that the outcome space of Bob is included in the outcome space of Alice.

Now, Bob rolls his dice and gets an outcome between 1 and 4, let's suppose that the outcome is a 2.

Now, Alice needs to roll a 2 in her 6-sided dice.

The 2 appears one time, and there are 6 possible outcomes:

The probability will be equal to the probability for each number, this i:

P = 1/6.

And will be the same for any outcome in Bob's roll, so the probability that they obtain the same number is 1/6.

Answer:

You must move the a and 8 to the other side of the equation. Just divide both sides by 8a.

B = c \ 8a.. c over 8a

The value for b is c/8a.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

8ab=c

Now, solving for b

8ab= c

ab= c/8

or, b = c/8a

Hence, the value for b is c/8a.

Answer:

The answer is below

Step-by-step explanation:

The time until recharge for a battery in a laptop computer under common conditions is normally distributed with mean of 270 minutes and a standard deviation of 50 minutes. a) What is the probability that a battery lasts more than four hours b) What are the quartiles (the 25% and 75% values) of batterylife? c) c) What value of life in minutes is exceeded with 95% probability? (Roundthe answer to the nearest integer.)

Solution:

The z score is used to determine by how many standard deviations the mean is above or below the raw score. If the z score is positive then the raw score is above the mean while if the z score is negative then the raw score is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean, \sigma=standard\ deviation[/tex]

Given μ = 270 minutes, σ = 50 minutes

a)

P(x > 4 hours) = P(x > 240 minutes)

[tex]z=\frac{x-\mu}{\sigma}\\ \\z=\frac{240-270}{50} =-0.6[/tex]

From the distribution table, P(x > 240) = P(z > -0.6) = 1- P(z < 0.6) = 1 - 0.2743 = 0.7257

c)  P(z > z*) = 0.95

1 - P(z < z*) = 0.95

P(z < z*) = 0.05

This corresponds to a z score of -1.645

[tex]z=\frac{x-\mu}{\sigma}\\ \\-1.645=\frac{x-270}{50} \\\\x=187.75 \ minutes[/tex]

For 75%, P(z < z*) = 0.75

This corresponds to a z score of 0.68

[tex]z=\frac{x-\mu}{\sigma}\\ \\0.68=\frac{x-270}{50} \\\\x=304 \ minutes[/tex]

c) For 25%, P(z < z*) = 0.25

This corresponds to a z score of -0.67

[tex]z=\frac{x-\mu}{\sigma}\\ \\-0.67=\frac{x-270}{50} \\\\x=236.5 \ minutes[/tex]

Answer:

The volume V of the region = 80

Step-by-step explanation:

The objective is to find the volume of the solid region bounded by z = 12 - y

Given that the portion of solid between the planes z = 12 - y and z = y; over the region R in the xy - plane bounded by y = x² and y = 6 - x²

Thus;  R = { (x,y)/-2 ≤ x ≤ 2, x² ≤ y 6 - x² }

Then the volume is computed as follows:

[tex]V = \int \int_R [(12 -y) -y] \ dy. dx[/tex]

[tex]V = \int^2_{-2} \int ^{6-x^2}_{x^2} (12-2y) \ dy \ dx[/tex]

[tex]V = \int^2_{-2}[ (12y-y^2]^{6-x^2}_{x^2} \ dx[/tex]

[tex]V = \int^2_{-2} \begin {bmatrix}{ 12 [6-x^2-x^2] - [(6-x^2)^2-(x^2)^2] \end {bmatrix} \ dx[/tex]

[tex]V = \int^2_{-2} \begin {bmatrix}{ 12 [6-2x^2] - [36-12x^2]] \end {bmatrix} \ dx[/tex]

[tex]V = \int^2_{-2} \begin {bmatrix}{ 72 -24x^2-36+12x^2 \end {bmatrix} \ dx[/tex]

[tex]V = \int^2_{-2} [36-12x ^2] \ dx[/tex]

[tex]V = \begin {bmatrix} 36x - \dfrac{12x^3}{3}\end {bmatrix}^2_{-2}[/tex]

[tex]V =2 \begin {bmatrix} 72 - \dfrac{96}{3}\end {bmatrix}[/tex]

V = 80

Complete Question

Newly purchased automobile tires of a certain type are supposed to be filled to a pressure of 30 psi. Let μ denote the true average pressure. Find the P-value associated with each of the following given z statistic values for testing H0: μ = 30 versus Ha: μ 30 when σ is known. (Give the answers to four decimal places.)

calculate for each

(a) z = 2.30

(b) z = -1.7

Answer:

a

[tex]p-value = 0.021448[/tex]

b

[tex]p-value = 0.08913[/tex]

Step-by-step explanation:

From the question we are told that

   The population mean is [tex]\mu = 30 \ psi[/tex]

   The null hypothesis [tex]H_o : \mu = 30[/tex]

    The alternative hypothesis is  [tex]H_a : \mu \ne 30[/tex]

Considering question a  

 Here  the test statistics is (a) z = 2.30  

 From the z table  the probability of  (Z >  2.30)  is  

      [tex]P(Z > 2.30 ) = 0.010724[/tex]

Generally the p-value is mathematically represented as

      [tex]p-value = 2 * P(Z > 2.30 )[/tex]

=>   [tex]p-value = 2 * 0.010724[/tex]

=>   [tex]p-value = 0.021448[/tex]

Considering question b

 Here  the test statistics is (a) z = -1.7

 From the z table  the probability of  (Z <  -1.7)  is  

      [tex]P(Z < -1.7 ) = 0.044565[/tex]

Generally the p-value is mathematically represented as

      [tex]p-value = 2 * P(Z < -1.70 )[/tex]

=>   [tex]p-value = 2 * 0.044565[/tex]

=>   [tex]p-value = 0.08913[/tex]

Answer:

The range of scores that can earn Jeremiah a B in the course is 80 - 100

Step-by-step explanation:

Average = total scores/number of exams

For an average of 80, considering the final score has twice the weight of the previous exams;

Note: since the final score has twice the weight of previous exams, it is considered a double score and counted twice

Let the lowest final score for a B grade be y

80 = (69 + 78 + 81 + 92 + 2 * y)/6

80 * 6 = (320 + 2y)

2y = 480 - 320

y = 160/2

y = 80

Let the highest final score for a B grade be z

89 = (69 + 78 + 81 + 92 + 2 * z)/6

89 * 6 = (320 + 2z)

2z = 534 - 320

z = 214/2

z = 107

Since, the highest score in the exam cannot exceed 100,

Therefore, the range of scores that can earn Jeremiah a B in the course is 80 - 100

The answer is option D. Note: the option is not properly formatted

D. x+y+z=200----------------1

    75x+45y+30z=12300-------2

     z=3y---------------3

Step-by-step explanation:

 In this problem, we want to model the expression to represent the situation

let the numbers of trees be

Coconut Palm trees be x,

Saw Palmetto Palm trees be y, and

Christmas Palm trees be z.

total trees =200

x+y+z=200----------------1

also costs are

Coconut Palm trees= $75 each

Saw Palmetto Palm trees = $45 each

Christmas Palm trees =$30 each

cost of all trees =$12,300

75x+45y+30z=12300----------------------2

z=3y---------------3

The system of equation is

x+y+z=200----------------1

75x+45y+30z=12300-------2

z=3y---------------3
