Answer:

52.74% probability that a randomly selected airfare between these two cities will be between $325 and $425

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 387.20, \sigma = 68.50[/tex]

What is the probability that a randomly selected airfare between these two cities will be between $325 and $425?

This is the pvalue of Z when X = 425 subtracted by the pvalue of Z when X = 325. So

X = 425

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{425 - 387.20}{68.50}[/tex]

[tex]Z = 0.55[/tex]

[tex]Z = 0.55[/tex] has a pvalue of 0.7088

X = 325

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{325 - 387.20}{68.50}[/tex]

[tex]Z = -0.91[/tex]

[tex]Z = -0.91[/tex] has a pvalue of 0.1814

0.7088 - 0.1814 = 0.5274

52.74% probability that a randomly selected airfare between these two cities will be between $325 and $425

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

From the spinner there are 8 possible outcomes (1 to 8)

From the coin, there 2 (heads or tails)

8*2=16

There are 16 possible outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

WE need to find the possible outcomes are there when spinning a spinner numbered from 1 to 8 and tossing a coin.

From the spinner, there are 8 possible outcomes (1 to 8)

From the coin, there 2 heads or tails;

8 x 2 = 16

Hence, There are 16 possible outcomes, when spinning a spinner numbered from 1 to 8 and tossing a coin.

Answer:

w= -9/8

Step-by-step explanation:

-1/3w -3/5 = 1/5w

+1/3w            +1/3 w

-3/5=1/5w+1/3w

Make common denominators to combine like terms of the right

-3/5=1/5w+1/3w

         *3       *5

-3/5=3/15w+5/15w

-3/5=8/15w

multiply both sides by the reciprocal of 8/15 which is 15/8

-3/5*15/8=8/15w*15/8

[tex]\frac{-3}{5}[/tex]*[tex]\frac{15}{8}[/tex] ----> cross reduce 5 in the denominator becomes 1 and 15 in the numerator becomes 3

[tex]\frac{-3}{1}[/tex]*[tex]\frac{3}{8}[/tex] -----> now multiply across

w= -9/8

Answer: -6/7

Step-by-step explanation:

-1/2w-3/5=1/5w

-w/2 - 3/5=w/5

Collect like terms

w/5 + w/2=-3/5

(2w + 5w)/10=-3/5

7w/10=-3/5

Cross multiply

7w x 5=-3 x 10

35w=-30

Divide both sides by 35

35w/35=-30/35

w=-6/7

The correct answer is $1.4 million

The insurance company must put $1.4 million into a bank account.

Insurance is a way to manage your risk. When you buy insurance, you purchase protection against unexpected financial losses. The insurance company pays you or someone you choose if something bad happens to you.

Given that, Marcus has a life insurance policy that will pay his family $35,000 per year if he dies. the interest rates are at 2.5%, we need to find the amount of the lump sum that the insurance company must put into a bank account,

Considering that the interest is Simple interest,

So, SI = PRT / 100

Here, the interest is 35000, P we need to find, r = 2.5 and T = 1

35000 = 2.5P/100

3500000 = 2.5P

P = 1400000

P = 1.4 millions

Hence, the insurance company must put $1.4 million into a bank account.

Answer:x=0

Step-by-step explanation:

Answer:

x = 0  

Step-by-step explanation:

Solve for x:

3 (8 x + 8) - 10 x = -6 (x - 4)

3 (8 x + 8) = 24 x + 24:

24 x + 24 - 10 x = -6 (x - 4)

Grouping like terms, 24 x - 10 x + 24 = (-10 x + 24 x) + 24:

(-10 x + 24 x) + 24 = -6 (x - 4)

24 x - 10 x = 14 x:

14 x + 24 = -6 (x - 4)

Expand out terms of the right hand side:

14 x + 24 = 24 - 6 x

Add 6 x to both sides:

14 x + 6 x + 24 = (6 x - 6 x) + 24

6 x - 6 x = 0:

14 x + 6 x + 24 = 24

14 x + 6 x = 20 x:

20 x + 24 = 24

Subtract 24 from both sides:

20 x + (24 - 24) = 24 - 24

24 - 24 = 0:

20 x = 24 - 24

24 - 24 = 0:

20 x = 0

Divide both sides of 20 x = 0 by 20:

(20 x)/20 = 0/20

20/20 = 1:

x = 0/20

0/20 = 0:

Answer:

  28.5 ft³

Step-by-step explanation:

The side length of the base is 1/4 of the perimeter, so is ...

  s = (10.1 ft)/4 = 2.525 ft

The area of the square base is the square of the side length, so is ...

  B = s² = (2.525 ft)² = 6.375625 ft²

The volume is given by ...

  V = 1/3Bh . . . . . where h is the height

  V = 1/3(6.375625 ft²)(13.4 ft) ≈ 28.4778 ft³

The volume of the pyramid is about 28.5 ft³.

Given: Dimensions of a rectangular prism are [tex]7.5\,\,inches,3\,\,inches\,,\,11.5\,\,inches[/tex]

To find: total surface area of the rectangular prism in square inches

Solution:

Length of the rectangular prism (l) = 7.5 inches

Breadth of the rectangular prism (b) = 3 inches

Height of the rectangular prism (h) = 11.5 inches

Total surface area of the rectangular prism = 2(lb+bh+hl)

The statement is not true. There is an error in the following step:

[tex]\frac{r^{k} * r^{k} }{r^{(k-1)} } = \frac{1 * 1}{1}[/tex]

Step-by-step explanation:

Here is the complete proof:

[tex]r^{k + 1} = r^{k + k - (k - 1)}[/tex]  (because k + k - (k - 1) = k + 1)

[tex]= \frac{r^{k} * r^{k} }{r^{(k-1)} }[/tex] (By laws of exponent)

[tex]= \frac{r^{k} * r^{k} }{r^{k} * r^{-1} } }[/tex]

[tex]= \frac{r^{k} * r^{k} * r^{1} }{r^{k}} }[/tex] (Since the power of r is a negative integer i.e. -1 it will shift to the numerator)

[tex]= r^{k} * r^{1}[/tex]  (We get this equation after canceling out the similar terms in numerator and denominator in previous step)

Answer:

To convert the feet to square feet we have to multiply the length by the width. In which, we should get the answer as well.

Our length is 2ft, since it's a rectangle the other side is 2ft as well.

Answer:

Step-by-step explanation:

Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.

If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:

  A' = (1/2)A = (1/2)(8, 4) = (4, 2)

Answer:

so find the area of the swuare first. 2 times 2 = 4. then you have to add that to the area of the triangle which is 1/2 times base times height. We know that the height is 1 and the base is 2 (from the square's common side shared) so its gonna be 2 times 1 which is 2 divided by 2 which is one soo its 4+1=5
