The number of bracelets and earrings sold is 10 and 16.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

Bracelets = x

Earings = y

Cost of bracelets = $5.00

Cost of the earrings =  $3.00

Now,

One day she sold 6 more earrings than bracelets and her sales totaled $98.

We can make two equations as,

y = x + 6 _____(1)

5x + 3y = 98 ______(2)

Substituting (1) in (2)

5x + 3(x + 6) = 98

5x + 3x + 18 = 98

8x = 98 - 18

8x = 80

x = 10

And,

y = 10 + 6

y = 16

Thus,

Bracelets = 10

Earings = 16

A histogram is a graphical representation of data that uses bars of different heights to represent the frequency of a given variable.

It is used to display the distribution of a categorical variable by showing the number of data points that fall into each of several categories.

To calculate the heights of the bars in a histogram, you first need to determine the number of data points in each category. This is done by counting the number of data points that fall into each category, and then dividing by the total number of data points. This gives us the histogram of each category, which can then be used to calculate the height of the bar. The formula for this is:

Bar Height = Frequency of Category / Total Number of Data Points

For example, say there are 10 data points in the category “A” and 20 data points in the category “B”. The frequency of “A” is 0.5 (10/20), and the frequency of “B” is 0.5 (20/20). The height of the bar for “A” would be 0.5, and the height of the bar for “B” would be 0.5.

Volume of the cone is 178 ft³.

Volume is defined as the space occupied within the boundaries of any three-dimensional shape.

Its SI unit is meter³.

Given,

Radius and height of cylinder and cone are same

Volume of cylinder = 534 ft²

Let radius be r and height be h

Volume of cylinder = πr²h

Volume of cone = 1/3πr²h

⇒ Volume of cone = 1/3 (Volume of cylinder)

⇒ Volume of cone = 1/3 × 534

⇒ Volume of cone = 178 ft³

Hence, 178 ft³ is the volume of cone.

To handle problems using samples that have a normal distribution, utilize the z-score formula.

The z-score of a measure X in a collection with mean and standard deviation is given by:

Z= x−μ/σ

The measure's standard deviations from the mean are determined by the [tex]Z-[/tex]score. We examine the p-value linked with the [tex]Z-[/tex]score in the [tex]Z-[/tex]score table after computing the [tex]Z-[/tex]score. This p-value is the probability that the measure's value is smaller than [tex]X[/tex], or the percentile of [tex]X[/tex]. The likelihood that the value of the measure exceeds [tex]X[/tex] is calculated by deducting [tex]1[/tex] from the pvalue.

This issue involves that:

Mean, μ[tex]=5.8[/tex]

Standard deviation,σ[tex]=0.9[/tex]

Only those who rank in the bottom 10% will be replaced.

So, if Z has a p value of 0.10, the warranty is equal to the value of X.

So it is X when

In a random sample of fourteen people, the mean time at lunch was 35.6 minutes.

Standard deviation of 8.2 minutes.

A common method to calculate the confidence interval for the mean of a normal distribution is to use the Z-score. For a 85% confidence interval, the Z-score is 1.44. Therefore, the confidence interval can be calculated as:

The confidence interval formula in statistics is used to describe the amount of uncertainty associated with a sample estimate of a population parameter.

Where,

n= Number of terms

[tex]$\overline{\mathrm{x}}[/tex]= Sample Mean

[tex]$\sigma[/tex]=Standard Deviation

[tex]$z_{\alpha / 2}[/tex]= Value corresponding to a2 in z table

[tex]$t_{\alpha / 2}[/tex]= Value corresponding to a2 in t table

[tex]$\alpha[/tex]=(1 - Confidence Level /100)

So for the given data, the confidence interval would be:

35.6 ± 1.44 * 8.2 / √14

35.6 ± 1.44 * 8.2 / 3.74

35.6 ± 3.76

The true mean of the population (the true mean of all high school students spending an average of how many hours each week doing sports) is between 22.6 and 29.0 hours.

The 95% Confidence Interval for the mean of the sample of 8 high school students spending an average of 25.8 hours each week doing sports is calculated by using the formula:

CI95 = (X ± (2*Standard Error))

Where X is the sample mean (25.8 hours) and the Standard Error is calculated as the standard deviation (3.2 hours) divided by the square root of the sample size (8).

Therefore, the 95% Confidence Interval is calculated as:

CI95 = (25.8 ± (2*(3.2/√8)))

CI95 = (25.8 ± 3.2)

CI95 = (22.6, 29.0)

The probability that all three members of the family visit the same station at the medical clinic is 1/27 (1/3 x 1/3 x 1/3). This is because each person has an equal chance of being assigned to any of the three stations and since there are three people in the family, the probability that they would all visit the same station is 1/3 multiplied by itself three times, which is equal to 1/27. The experiment is recording the station number for each member and since the incoming individuals are assigned to any of the three stations randomly, the probability that all three members visit the same station is 1/27.

The probability that both cards are aces is 0.45%.

Given that,

A standard 52-card deck is used to deal two cards. In other words, two cards are uniformly and randomly sampled without being replaced.

There are four aces in the deck of 52 cards. The likelihood of drawing an ace when you draw a card is 4/52=1/13.

There are only 51 cards left when the second card is drawn, and since an ace has already been drawn, just 3 of those cards are still in the deck. Therefore, there is a 3/51 chance of drawing the second ace. The likelihood that both of these events occur is 1/13 x 3/51 = 0.00452. (approx). Thus, there is a 0.45% chance of drawing two aces.

V = πr^2h. Eq1. And. A =2πr^2 +2πrh. Eq2

From Eq1 h = V/πr2. Eq3

Sub Eq3 into Eq2

Then A = 2πr^2 + 2πr ×(V/πr^2). And V =16π

So A = 2πr^2 + 32π/r

dA / d r = 4πr - 32π/r^2 = 0 at max/ min

r^3 -8 =0

r^3 =8

Answer:

The answer is $99

Step-by-step explanation:

The total money Lincoln has to pay for his family to see a movie and share 4 snacks is $59. When Lincoln buys x snacks to share, the total cost would be $39 plus $5x.

The costs that Lincoln has to pay consists of two parts: the cost for the tickets and the cost for snacks. Lincoln himself and his two kids makes for 3 people in total. A ticket for each person costs $13, so the cost for tickets is 3 multiplied by $13, which equals $39.

If Lincoln buys 4 snacks for everybody to share, each at a price of $5, these snacks would cost 4 multiplied by $5, which is $20 in total. So, the total cost would be $39 (for tickets) plus $20 (for snacks), resulting in a total of $59.

For the case when Lincoln buys x snacks for everybody to share, just replace the number 4 with x in our snacks calculation. That would be $5x for the snacks cost. The total cost Lincoln would have to pay is then, still $39 for tickets, plus $5x for snacks.

Based on the information, she can infer that the children meet at 7:00 pm EST to play video games. Additionally, the best flight ticket for Morgan is Sunset airline since it is $12 cheaper than Autumn airline.

According to the information, Joey is in Ohio and Grayson is in Oregon. These two states have different time zones, in the case of Ohio it is (-5) and in the case of Oregon it is (-8). Therefore, they connect to play at 7:00 pm EST because when Grayson arrives at his house at 4:00 pm, in Ohio it is 7:00 pm. However, Joey is already connected since 4:20 pm that he arrived at his house.

To identify which is the best ticket for Morgan, we must add all the services that she wants to include in her plane trip and then find the difference between the value of the two tickets.

Sunset airline:

$219 + $80 + $30 = $329
