The volume of the triangular prism is 54 cubic units.

Answer: 113.04 cm³

Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is shown below.

[tex]V = \frac{4}{3} \pi r^{3}[/tex]

Here, we are given that our sphere has a radius of 3 centimeters.

So plugging into the formula, we have [tex](\frac{4}{3})(\pi)(3 cm)^{3}[/tex].

Start by simplifying the exponent.

(3 cm)³ is equal to 3 centimeters · 3 centimeters ·

3 centimeters or 27 cm³.

So we have [tex](\frac{4}{3})(27 cm^{3})(\pi)[/tex].

Notice that we can cross-cancel 3 and 27 to 1 and 9.

So we have (4)(9 cm³) which is equal to 36 cm³.

So we have 36π cm³.

So the volume of the sphere is 36π cm³.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the volume by plugging in 3.14 for π.

So we have (36)(3.14) which is equal to 113.04 which means

that the volume of approximately equal to 113.04 cm³.

Answer:

D = 2.45 mm

Step-by-step explanation:

D = C ÷ π

D = 7.7 ÷ 3.14

D = 2.4509

D = 2.45 mm

To find the length of the diameter of a circle when the circumference is given, divide the circumference by π.

To find the diameter of a circle when only the circumference is given, divide the circumference by π (approximately 3.1416). The formula to find the diameter is:

Diameter = Circumference / π

In this case, the circumference is 7.7mm. So, the diameter would be:

Diameter = 7.7mm / 3.1416 ≈ 2.448mm

Therefore, the length of the diameter, rounded to 3 significant figures, is approximately 2.45mm.

To determine which scatter plot displays data most effectively, it is crucial to ensure that the explanatory variable is positioned on the x-axis and that the plot uses a scale that makes it easy to identify trends without obscuring data points. The best scatter plot will clearly demonstrate the relationship between two variables and indicate potential patterns that may suggest a correlation or relationship worthy of linear regression analysis.

The question revolves around determining which scatter plot displays data most effectively, adhering to the guidelines of using a reasonable scale on both axes and positioning the explanatory variable on the x-axis. An essential aspect of a scatter plot is that it should clearly indicate the relationship between two variables, allowing for pattern identification and assessment of potential for linear regression.

By convention, data visualization practices dictate that the x-axis should represent the independent variable (explanatory variable), which is the variable that is presumed to cause changes in another variable. The y-axis should depict the dependent variable, whose changes are investigated to be a result or effect of the independent variable. A good scatter plot employs a scale that accurately encompasses all data points without distorting the visual perception of their distribution, making it easier for viewers to identify trends, clusters, or patterns that might suggest a correlation or relationship worthy of linear regression analysis.

In selecting the best scatter plot, one must also consider the clarity of the plot in demonstrating data distribution and potential correlations. The plot must be fine-tuned to avoid too large or too small scales, which can obscure data trends or require unnecessarily large graphical space. Additionally, attention should be paid to ensuring the number of significant figures on the axis values does not exceed those in the measurements. The ideal scatter plot employs a scale and plotting strategy that maximizes visualization efficiency, facilitating easy analysis and interpretation of the data's underlying patterns.

Graph A has explantory variable on x axis and response variable on y- axis also their scale is reasonable here.

Step-by-step explanation:

The question is not properly formatted, here is how it should be formatted.

A bag contains 6red jelly beans, 4 green jelly beans, and 4 blue jelly beans. If we choose a jelly bean, then another jelly bean without putting the first one back in the bag, what is the probability that the first jelly bean will be green and the second will be red

Step one

This is selection without replacement.

Sample space

6red jelly beans,

4 green jelly beans, and

4 blue jelly beans.

S= 6+4+4= 14

Probability that the first jelly bean will be green = 4/14= 2/7

Without replacement, Probability that the second jelly bean will be red = 6/13

Hence for the two selections the probability is= 2/7*6/13= 12/91

To find the number of white flowers, we subtract the total number of red flowers (64) from the total number of flowers (208), resulting in 144 white flowers.

The student's question involves calculating the number of white flowers in a flower bed given the total number of flowers and the number of rows of red flowers.

There are 26 rows of flowers in total, and each row contains 8 flowers. If 8 rows consist of red flowers, we can calculate the number of white flowers by subtracting the red flowers from the total number of flowers.

Here are the steps we'll take to solve the problem:

Multiply the total number of rows by the number of flowers per row to find the total number of flowers.

Total flowers = 26 rows * 8 flowers/row = 208 flowers

Multiply the number of rows of red flowers by the number of flowers per row to find the total number of red flowers.

Total red flowers = 8 rows * 8 flowers/row = 64 flowers

Subtract the number of red flowers from the total number of flowers to find the number of white flowers.

Total white flowers = Total flowers - Total red flowers = 208 flowers - 64 flowers = 144 white flowers.

Answer:

  h'(x) = (-3x^3 +2x)/e^(3x)

Step-by-step explanation:

The formula for the derivative of a quotient is ...

  (u/v)' = (vu' -uv')/v²

Using u = (x^3 +x^2) and v = e^(3x), this becomes ...

  h'(x) = (e^(3x)(3x^2 +2x) -(x^3 +x^2)(3)(e^(3x))/e^(6x)

  h'(x) = (-3x^3 +2x)/e^(3x)

Answer:

To find out when they coincide again, the least common multiple between both numbers must be calculated:

24 14 | 2

12   7 | 2

6    7 | 2

3    7 | 3

1     7 | 7

1     1

Therefore the least common multiple is:

2 * 2 * 2 * 3 * 7 = 168

This means that they will coincide again at 168 seconds, when the first musician has struck 7 times (168/24) and the other 12 times (168/14)

And you have to subtract in the math

Answer:

1.  Subtraction property of equality; multiplication property of equality; division property of equality

For this question, you simply have to state the operation that is occurring.

2.  To solve this, simplify the equation so that it is in y=mx+b form.  From the equation, find two points so that you can plot a line.

4x + y = 6x - 1

y = 2x - 1

-1 is the y-intercept.  This means that you can place a point at (0,-1) which is the -1 on the y (vertical) axis.

For the second point, you can plug any number for the x-value that will stay within the given graph.  I am going to use 2.  

y = 2(2) - 1

y = 4 - 1

y = 3

This gives you the point (2, 3).  Plot the points (0, -1) and (2, 3).  You will be able to draw a line from that.

The chart showing the quantities and prices is;

Best Deal 1

Quantity of Flour Price

3 pounds $5.25

5 pounds $9.75

7 pounds $12.60

10 pounds $14.20

12 pounds $18.24

Answer:

difference between last weeks best deal = $0.3

Step-by-step explanation:

Let's calculate the unit price for each of the quantities in the chart.

For quantity of 3 pounds;

We have; unit price = 5.25/3 = $1.75

For 5 pounds;. Unit price = 9.75/5 = $1.95

For 7 pounds; unit price = 12.6/7 = $1.8

For 10 pounds; unit price = 14.2/10 = $1.42

For 12 pounds; unit price = 18.24/14 = $1.3

Thus, last weeks best deal is the lowest = $1.3

Thus; difference between last weeks best deal is given as;

= this weeks best deal - last weeks best deal

This gives;

$1.6 - $1.3 = $0.3

Answer:

Second time: 8 tortillas

Area of tortillas in the first batch: 160.8 in2

Step-by-step explanation:

Let's say that the amount of dough to make a tortilla is x.

So, in the first time, the amount of dough used is 10 * x = 10x

Then, she made the tortillas 25% larger, so the amount of dough used for each tortilla now is 1.25x

So, using the same amount of dough (10x), the amount of tortillas she can make is:

10x / 1.25x = 8 tortillas

If the area of the larger tortilla is 201 in2, and this tortilla is 25% larger than the ones in the first batch, to find the area of the inicial tortillas we just need to divide this new area by 1.25:

Area of first tortillas = 201 / 1.25 = 160.8 in2

Answer:

0.9826 = 98.26% probability that a seat will be available for every person holding a reservation and planning to fly.

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

Can be approximated to a normal distribution, using the expected value and the standard deviation.

The expected value of the binomial distribution is:

[tex]E(X) = np[/tex]

The standard deviation of the binomial distribution is:

[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]

Normal probability distribution

Problems of normally distributed samples can be 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.

When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].

In this problem, we have that:

6% of the people who make reservations on a certain flight do not show up for the flight. So 100-6 = 94% show up, which means that [tex]p = 0.94[/tex]

190 tickets, so [tex]n = 190[/tex]

So

[tex]\mu = E(X) = np = 190*0.94 = 178.6[/tex]

[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{190*0.94*0.06} = 3.27[/tex]

Find the probability that a seat will be available for every person holding a reservation and planning to fly.

At most 185 people show up.

Using continuity correction, we have to find [tex]P(X \leq 185 + 0.5) = P(X \leq 185.5)[/tex], which is the pvalue of Z when X = 185.5. So

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

[tex]Z = \frac{185.5 - 178.6}{3.27}[/tex]

[tex]Z = 2.11[/tex]

[tex]Z = 2.11[/tex] has a pvalue of 0.9826

0.9826 = 98.26% probability that a seat will be available for every person holding a reservation and planning to fly.
