A set of shirt prices are normally distributed with a mean of 454545 dollars and a standard deviation of 555 dollars. what proportion of shirt prices are between 373737 dollars and 59.3559.3559, point, 35 dollars? you may round your answer to four decimal places.

Answer:

Step-by-step explanation:

7 blue cars out of 38 cars.

To find the percentage you just divide using your calculator and you should get something like this :

\(\frac{7}{38}\) = 0.1842105263

Then you just round that to the nearest hundredth.

If you round 0.184 to the nearest hundredth, it will be 0.18 (You have to round down since the number 4 in the thousandth place is smaller than 5)

To rewrite the compound interest equation in the form B(t) = P(1 + rn)^nt, we need to compare it with the given equation B(t) = 100(1.1664)^t.

Let's analyze the given equation: B(t) = 100(1.1664)^t

Comparing this with the desired form, we can see that:

P = 100

1 + rn = 1.1664

nt = t

Since n = 2, we have:

1 + rn = 1.1664

2t = t

From the second equation, we can deduce that t = 0. So, let's substitute this value back into the first equation to solve for r.

1 + rn = 1.1664

1 + r(0) = 1.1664

1 = 1.1664

Since the equation is not satisfied for any value of r, we can conclude that there is an error or inconsistency in the given compound interest equation B(t) = 100(1.1664)^t. As a result, we cannot determine the interest rate, r, as a percentage.

I will assume the following:

The challenge of this exercise comes from using the pythagorean theorem and setting up a few equations.

Given that we have a segment 36 units long and another segment that is 16, it is trivial to get the other segment, 20. Additionally, there are two sides that I want to name so that way I can make a couple of substitutions. I will call these side a and side b. (see attachment 1)

Now comes with setting up three equations. I will start with the two smaller triangles, using side a and side b. See attachments 2 and 3.

Now with the big triangle. I will set up one last equation. See attachment 4.

Given what we know about attachment 2 and 3, we can make two substitutions. See attachment 5. I assume you know how to do the rest and arrive at your only real solution.

Answer:

 y = 2x + 5

y = -3x - 10= -23

Step-by-step explanation:

 y = 2x + 5

y = -3x - 10 = -23

=====================================================

Explanation:

y = 2x+5 .... start with the first equation

-3x-10 = 2x+5 .... replace y with -3x-10 since y = -3x-10

The term "substitution" is the same as "replacement". Think of how the substitute teacher is a temporary replacement for your actual teacher.

Now we solve for x. Get all the x terms to one side and the non x terms to the other side

-3x-10 = 2x+5

-10-5 = 2x+3x

-15 = 5x

5x = -15

Next we divide both sides by 5 to isolate x

5x/5 = -15/5

x = -3

Now that we have the value of x, we can use this to find y. Pick any of the two equations to plug in this x value

y = 2x+5 = 2*(-3)+5 = -6+5 = -1

or

y = -3x-10 = -3(-3)-10 = 9-10 = -1

Either way, x = -3 leads to y = -1.

The fact we get the same y value helps us confirm we have the correct x value.

The solution to the system is (x,y) = (-3, -1)

This linear system is considered consistent and independent.

If you graph y = 2x+5 and y = -3x-10, you will find that the two lines intersect at (-3, -1) as the diagram shows below.

The correct answer is option (e). The sum of the lengths in inches of all of its interior diagonals is 40√2.

The surface area of a rectangular box can be expressed as 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the box, respectively. Since the total surface area is 94 square inches and the sum of the lengths of all its edges is 48 inches, we can write an equation using these variables. Solving for l, w, and h, we find that the length, width, and height are 6, 7, and 4 inches, respectively.

The sum of the lengths of all interior diagonals can then be found using the Pythagorean theorem. The result is,

√(l^2 + w^2 + h^2) = √(6^2 + 7^2 + 4^2)

= √(36 + 49 + 16)

= √101

= 10√2.

The sum of the lengths of all interior diagonals is then equal to 2(10√2) = 40√2.

Hilary studied for a total of 2 hours and 5 minutes this week.

If Hilary studied for 25 minutes each day for five days this week, we can calculate the total study time by multiplying the number of minutes studied per day (25) by the number of days (5):

25 minutes/day × 5 days = 125 minutes

To convert this to hours and minutes, we need to divide the total minutes by 60 (since there are 60 minutes in an hour) to get the number of hours and find the remainder as minutes.

125 minutes ÷ 60 = 2 hours and 5 minutes

Therefore, Hilary studied for a total of 2 hours and 5 minutes this week.

B. The statement is true.

(a) When performing an ANOVA with the data the alternative hypothesis is at least two of the restaurants have different mean delivery times.

(b)75.8

Analysis of variance. or ANOVA, is a statistical method that separate observed variance data into different components to use for additional tests. A one way ANOVA is used for three or more groups of data, to gain information about the relationship between the dependent and independent variables.

The ANOVA table shows how the sum of squares are distributed according to source of variation, and hence the mean sum of squares.

It is given that a pizza lover wants to compare the average delivery times.

Therefore the null hypothesis and alternate hypothesis implies that,

H₀ =  all restaurants have equal mean delivery time

Hₐ = at least two restaurants have different two deliveries

Hence the alternate hypothesis for performing an ANOVA with the data is at least two of the restaurants have different mean delivery times.

The alternate hypothesis (Hₐ) defines that there is a statistically important relationship between two variables. Whereas null hypothesis states that is no statistical relationship between the two variables.

To determine the probability of flipping heads on a coin given that a 4 was rolled on a 6-sided die, we can use Bayes' theorem.

Bayes' theorem allows us to update our prior probability with new evidence. In this case, we want to find the probability of flipping heads on a coin (H) given that a 4 was rolled on a 6-sided die (F). Bayes' theorem states:

P(H|F) = (P(F|H) * P(H)) / P(F)

We need to calculate three probabilities: P(F|H), P(H), and P(F).

P(F|H) represents the probability of rolling a 4 on the die given that the coin flip resulted in heads. Since the coin flip and the die roll are independent events, this probability is simply 1/6.

P(H) is the prior probability of flipping heads on the coin, which is 1/2 since there are two equally likely outcomes for flipping a fair coin.

P(F) represents the probability of rolling a 4 on the die, regardless of the coin flip. This probability can be calculated by summing the probabilities of rolling a 4 given both heads and tails on the coin. Since each outcome has a probability of 1/6, P(F) = (1/2 * 1/6) + (1/2 * 1/6) = 1/6.

Plugging these values into Bayes' theorem:

P(H|F) = (1/6 * 1/2) / (1/6) = 1/2

Therefore, the probability of flipping heads on the coin given that a 4 was rolled on the die is 1/2.

The student's weighted mean, based on the given scores and weights, is 81.25.

To calculate the student's weighted mean, we need the scores for each source and their corresponding weights. Since you haven't provided the specific scores, I will demonstrate the calculation using placeholder values.

Let's assume the student's scores are as follows:

Lab Reports: 85

Quizzes: 90

Midterm Exam: 75

Final Exam: 80

The weights for each source are as follows:

Lab Reports: 30%

Quizzes: 10%

Midterm Exam: 25%

Final Exam: 35%

To calculate the weighted mean, we multiply each score by its corresponding weight and then sum the results.

Weighted mean = (Lab Reports × Lab Reports Weight) + (Quizzes × Quizzes Weight) + (Midterm Exam × Midterm Exam Weight) + (Final Exam × Final Exam Weight)

Substituting the values:

Weighted mean = (85 × 0.30) + (90 × 0.10) + (75 × 0.25) + (80 × 0.35)

Weighted mean = 25.5 + 9 + 18.75 + 28

Weighted mean = 81.25

Answer:

The price of each big peach is: $0.45

Step-by-step explanation:

Given that

Total peaches = 270

The ratio of small to medium to big peaches

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

Now

\(Small\ peaches = \frac{2}{9} * 270 = 60\\Medium\ peaches = \frac{4}{9}*270 = 120\\Big\ peaches = \frac{3}{9} *270 = 90\)

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

So,

Price of one small peach = $0.25

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

\(Price\ of\ all\ medium\ peaches = Total\ cost-(Cost\ of\ small\ peaches+ Cost\ of\ medium\ peaches)\\= 91.50 - (15+36) \\=91.50-51\\=40.5\)

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches

So,

\(Cost\ of\ one\ peach = \frac{40.5}{90} = 0.45\)

Hence,

The price of each big peach is: $0.45

0.45 cent

Given that

Total peaches = 270

The ratio of small to medium to big peaches.

2:4:3

We can use this ratio to find the number of peaches in each group

First of all we have to find the sum of ratios

That is

2+4+3 = 9

It is also given that total cost is $91.50

We will have to find the cost of small and medium peaches and then subtract both from the total cost to find the price of big peaches.

Total cost = 0.25*60 = 15

Price of one medium peach = $0.30

Total cost = 0.30*120 = 36

To find the cost of one big peach, the cost of big peaches will be divided by total number of peaches.

So the price of each big peach is: $0.45
