Use the net to find the surface area of the rectangular prism.

Answers

Answer:

220

Step-by-step explanation:

The surface area is  given by

SA = 2 ( lw+wh+lh)  where  l is length h is height and w is width

SA = 2(3*4 + 3*14+ 4*14)

     = 2(12+42+56)

    = 2(110)

    = 220

The calculated surface area of the net is 208 square units

Finding the surface area of the net

From the question, we have the following parameters that can be used in our computation:

The net of the prism

The surface area of the net is then calculated as

Surface area = Area of big rectangle + 2 * Area of small rectangle

So, we have

Surface area = (14 + 3 + 14) * 4 + 2 * 3 * 14

Evaluate

Surface area = 208

Hence, the surface area of the net is 208 square units

Which is the correct first step in finding the height of a cylinder with a volume of 178 cubic inches and a radius of 8 inches?
Va sern
8= (178)
WV = arh
V = x+(8)2 + 178
V= seh
V= 548)? (178)
V = xin
178 = $(8)

Answers

The correct first step is to apply the formula for the volume of a cylinder, [tex]\(V = \pi r^2 h\)[/tex], and then rearrange it to solve for the height by dividing the volume by [tex]\(\pi r^2\).[/tex] (Last option)

The correct first step in finding the height of a cylinder with a given volume and radius is to use the formula for the volume of a cylinder:[tex]\(V = \pi r^2 h\)[/tex], where V is the volume, r is the radius, and h is the height.

To solve for h, we must rearrange the equation to isolate h.

Therefore, the correct first step would be to divide both sides of the equation by [tex]\(\pi r^2\)[/tex] to solve for h:

[tex]\[ h = \frac{V}{\pi r^2} \][/tex]

In the case given where the volume (V) is 178 cubic inches and the radius (r) is 8 inches, it would look like:

[tex]\[ h = \frac{178}{\pi \times 8^2} \][/tex]

After performing the calculations, this will give us the height (h) of the cylinder.

So the correct first step would be to apply the formula for the volume of a cylinder, [tex]\(V = \pi r^2 h\)[/tex], and then rearrange it to solve for the height by dividing the volume by [tex]\(\pi r^2\).[/tex]

The amount of icing on a Cuppie Cake large cupcake follows a Normal distribution, with a
mean of 2 ounces and a standard deviation of 0.3 ounce. A random sample of 16 cupcakes
is selected every day and measured. What is the probability the mean weight will exceed
2.1 ounces? (2 points)
O 0.9088
0.3694
0.0912
0.6306
0.075

Answers

The probability of mean weight will exceed 2.1 ounces is 0.0912.

To solve this problem, we need to calculate the probability that the mean weight of the icing on a sample of 16 cupcakes exceeds 2.1 ounces, given that the distribution of the icing weights is normal with a mean of 2 ounces and a standard deviation of 0.3 ounce.

First, we need to find the standard error of the mean (SEM) for the sample of 16 cupcakes. The SEM is calculated by dividing the population standard deviation by the square root of the sample size:

[tex]\[ SEM = \frac{\sigma}{\sqrt{n}} = \frac{0.3}{\sqrt{16}} = \frac{0.3}{4} = 0.075 \][/tex]

Now, we need to find the z-score for the value of 2.1 ounces. The z-score is calculated by subtracting the population mean from the value in question and then dividing by the SEM:

[tex]\[ z = \frac{\bar{x} - \mu}{SEM} = \frac{2.1 - 2}{0.075} = \frac{0.1}{0.075} = \frac{4}{3} \approx 1.3333 \][/tex]

Next, we look up this z-score in the standard normal distribution table or use a calculator to find the probability of a z-score being less than 1.3333. This gives us the probability that the mean weight of the icing is less than or equal to 2.1 ounces.

[tex]\[ P(Z < 1.3333) \approx 0.9088 \][/tex]

However, we want the probability that the mean weight exceeds 2.1 ounces, so we need to subtract this value from 1 (the total probability):

[tex]\[ P(\bar{x} > 2.1) = 1 - P(Z < 1.3333) = 1 - 0.9088 = 0.0912 \][/tex]

Therefore, the probability that the mean weight of the icing on a sample of 16 cupcakes will exceed 2.1 ounces is 0.0912.

Answer: Choice 2)  sin(B) = cos(90-B)

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

So we end up with

sin(90-B) = cos(B)

The given expression is 8(1/2y+3/4)

To make it easier put 8/1, so we can multiply fractions without getting confused.

First step is 8/1•1/2, for the numerator or top, we have 8•1=8. The denominator or bottom, we have 1•2=2. Now we put them back together like a puzzle. The numerator is 8, and the denominator is 2. So we put eight over two 8/2. Eight divided by two equals four. 8/2=4

So far we've solved for the first half. Don't forget the variable at the end of the first section!

We have 4y+(3/4) now.
But we don't stop there. The eight on the outside of the parenthesis also apply to 3/4.

Same thing we put 8/1 and multiply top and bottom against 3/4.
8•3=24, for the numerator or top value.
1•4=4 for the denominator or bottom value. We combine them back into a fraction, so we have 24/4. Now we don't stop there. We need to simplify the fraction so twenty four divided by four equals six, or 24/4=6.

We plug it back into the original equation with both our new answers, leaving us with 4y+6

Two angles are supplementary. The first angle is 8x degrees. The second angle is(4x+12). Determine the measure of each angle.

Answers

Answer:

The measure of the angles are 112 degrees and 68 degrees.

Step-by-step explanation:

Two angles are supplementary if they add up to 180 degrees.

The first angle is 8x degrees.

The second angle is (4x+12) degrees.

Therefore:

8x+4x+12=180 degrees

12x+12=180

12x=180-12

12x=168

Divide both sides by 12

x=14 degrees

Substituting x in the given angles:

8x =8*14=112 degrees

4x+12=4(14)+12=68 degrees

Therefore, the measure of the angles are 112 degrees and 68 degrees.

Brian scored an 80% on a Chemistry Exam. The average on the exam was a 68%, with a standard deviation of
5%. What is Brian's z-score?

Answers

Answer:

Brian's z-score is 2.4

Step-by-step explanation:

The equation for z score is presented as follows;

[tex]z = \frac{x- \mu}{\sigma}[/tex]

Where:

x = Score = 80%

μ = Mean = 68%

σ = Standard deviation = 5%

Plugging in the values gives;

[tex]z = \frac{80- 68}{5} =2.4[/tex]

Therefore, Brian's z-score on the Chemistry Exam, where the mean is 68%, the standard deviation is 5% and Brian's score is 80% = 2.4.

Final answer:

Brian's z-score is 2.4, calculated using the formula Z = (X - \) / \ by substituting X with Brian's score, \ with the mean score, and \ with the standard deviation. A z-score of 2.4 means Brian scored well above average.

Explanation:

Brian scored an 80% on a Chemistry Exam, where the average was 68%, with a standard deviation of 5%. To find Brian's z-score, use the formula:

Z = (X - \) / \

Where X is Brian's score, \ is the mean score, and \ is the standard deviation. Plug in the values:

Z = (80 - 68) / 5 = 12 / 5

Brian's z-score is 2.4, which means his score is 2.4 standard deviations above the mean. A z-score tells how many standard deviations an element is from the mean. If it's positive, the score is above average; if negative, below average.

if rectangle a and rectangle b have a ratio of similarity of 5:4, what is the area of rectangle B if the area of the rectangle A is 24 square units

Answers

Answer:

the answer is 30 this is because if you rectangle b is 24 then rectangle a is 30 like if you simplify 30:25 if you divide it by 6 it will give 5:4

Step-by-step explanation:

Final answer:

The area of rectangle B is approximately 15.36 square units.

Explanation:

To find the area of rectangle B, we can use the ratio of similarity.

The ratio of similarity between rectangle A and rectangle B is 5:4.

Since the area of rectangle A is 24 square units, we can set up the equation:

(area of B) / (area of A) = (side length of B)² / (side length of A)².

Substituting the values, we get

(area of B) / 24 = (4/5)².

Solving for the area of B, we have

(area of B) = 24 * (4/5)²

                 = 24 * 16/25

                 = 384/25

                 = 15.36 square units.
