Suppose X and Y are non-empty sets. Which set contains more elements: X U Y or X ∩ Y? Explain.

Answers

Answer:

The union of two sets is guaranteed to result in an equal or larger set than if they were intersected.

This only makes sense because intersecting sets is exceptional, only values that already exist in both sets are in the result.  Whereas a union of two sets gives you all of the content of both.

The only time when an intersection is even equal to a union is when the two sets are identical.  If they aren't then the intersection will be smaller.

74.5 in²

Step-by-step explanation:

surface area of the given image

= 1/2 (1.5) 2 (2 triangular sides)     =  3 in²

= 2 x 11 (2 rectangular sides)         = 44 in²

= 2.5 x 11 (rectangular bot base)   = 27.5 in²  

                             

total                                                = 74.5 in²      

The student council is making corsages to sell at prom. They spent $350 on materials such as
flowers, ribbons, elastic and pins. They are selling the corsages for $7.50 each. They need to
earn $700 to pay for prom decorations. Which inequality will determine the correct number of
corsages, c, that the class needs to sell to pay for the prom decorations?

Answers

Answer:

The inequality 7.50c - 350 ≥ 700 can be used.

Step-by-step explanation:

Given that:

Amount spent on materials = $350

Amount the council needs to earn = $700

Selling price per corsage = $7.50

Number of corsages sold = c

Selling price per corsage * Number of corsages sold - amount spent on materials ≥ amount needs to be earned

[tex]7.50c - 350 \geq 700[/tex]

Hence,

The inequality 7.50c - 350 ≥ 700 can be used.

Enter the difference as a mixed number

Answers

Answer:

The answer is 2[tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

So you get 2 4/5

Answer:

28/10

Step-by-step explanation:

To make it easier, you can multiply the whole numbers by the denominators, and then add the numerator to the total. For the first one, do 4 x 10 = 40. Then add 5, and you get 45. The fraction will then be 45/10. For the second one, 1 x 10 = 10. Then add 7, and you get 17. The fraction will be 17/10.

Next, subtract the numerators because both of the denominators are equal. You then get 28/10 because 45 - 17 = 28.

28/10 is your mixed number fraction.

The speed of light is 3 x 10 8 meters per second (m/s). What is the speed of light in miles per year (mi/yr)

Answers

Answer:

the  speed of light in miles per year is 5.88 × 10^12 mi / year

Step-by-step explanation:

The computation of the speed of light in miles per year is shown below;

As we know that

1 m/sec = 1 ÷ 1609  mi/sec

3 ×10^8 m/sec = (3 × 10^8) ÷ (1609)

= (3 × 10^8 × 60 × 60 × 24 × 365) ÷ (1609)

= 5.88 × 10^12 mi / year

Hence, the  speed of light in miles per year is 5.88 × 10^12 mi / year

A Government company claims that an average light bulb lasts 270 days. A researcher randomly selects 18 bulbs for testing. The sampled bulbs last an average of 260 days, with a standard deviation of 90 days. If the CEO's claim were true, what is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days

Answers

Answer:

31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

When the distribution is normal, we use 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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question, we have that:

[tex]\mu = 270, \sigma = 90, n = 18, s = \frac{90}{\sqrt{18}} = 21.2[/tex]

What is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days?

This is the pvalue of Z when [tex]X = 260[/tex]. So

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

By the Central Limit Theorem

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

[tex]Z = \frac{260 - 270}{21.2}[/tex]

[tex]Z = -0.47[/tex]

[tex]Z = -0.47[/tex] has a pvalue of 0.3192.

31.92% probability that 18 randomly selected bulbs would have an average life of no more than 260 days

Amy runs a bike rental business. She currently charges $36 per bike
rental and averages 60 rentals a week for an average weekly income of
$2,160. She predicts that she may lose 2 rentals a week for every one-

- 2p-12p+2160 to model her prediction. Which of the following is
the equivalent expression to reveal the maximum income based upon
Amy's model?

Answers

Answer:

b

Step-by-step explanation:

The equivalent expression to reveal the maximum income based upon Amy's model is -2(p+ 3)²+ 2178.

What is Expression?

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.

Given:

The model for Amy Situation is -2p²- 12p+ 2160

Now, - 2(p+ 3)²+ 2178

=  -2p² - 18 - 12p + 2178

=  -2p² - 12p + 2160

and, -2(p+ 6)² +2160

=  -2p² - 72 - 24p + 2160

=  -2p² - 24p + 2088

and, - 2(p-3)²+ 2178

=  -2p² - 18 + 12p + 2178

=  -2p² + 12p + 2160

Hence, the equivalent expression to reveal the maximum income based upon Amy's model is -2(p+ 3)²+ 2178.

For runners in a race, a low time means a faster run. The winners in a race have the shortest running times. Is it more desirable to have a finish time with a high or a low percentile when running a race

Answers

Answer:

It is desirable to have finish time with low percentile.

Step-by-step explanation:

It is more desirable to have a low percentile for finish time for runners when running a race. A low percentile means a short time, which is faster.

When competing in a race, a low percentile finish time is preferable. 

What is the relationship between speed and time?

Speed is the rate at which a distance changes over time. So speed and time are inversely proportional.

In a race, the person who runs faster will finish the race first. So a faster run takes less time.

Hence, it is more desirable to have a low percentile finish time during a race.
