Answers

99.7% of the students scored between (44.67 , 56.33) i.e.

between 44 and 56.

On Subtracting 1 from your sample size, we get

100 – 1 = 99.

On Subtracting confidence level from 1, and then divide by two.

(1 – .997) / 2 = 0.0015

Now, df = 99 and α = 0.0015

from the table at df = 99 we got 2.262.

Divide your sample standard deviation by the square root of your sample size.

28 / √(100) = 2.8

Now, 2.262 × 2.8 = 6.33

So, the confidence interval be,

(100 - 6.33 , 100 + 6.33) = (44.67 , 56.33)

Hence, 99.7% of the students scored between (44.67 , 56.33) i.e.

between 44 and 56.

The cost of a movie ticket is \$ 8. 00$8. 00 for each adult and \$ 6. 00$6. 00 for each child. Assume you have \$ 40. 00$40. 00 to spend on tickets. Write an equation in standard form to represent the number of adult tickets, xx, and the number of children's tickets, yy, you can buy with your \$ 40. 00$40. 0.

Answers

Since an adult movie ticket costs $8 and a kid movie ticket costs $6, the equation for the given condition is 8x+6y=40.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical phrase with two equal sides and an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

The cost of movie ticket for adult= $8

The cost of movie ticket for adult= $6

Total amount to spend= $40

Let x be the number of adult and y be the number of children,

8x+6y=40

The equation for the given condition is 8x+6y=40 as the cost of movie ticket for adult is $8 and for children, it is $6.

There are 123 different possibilities. Therefore, we can derive from the multiplication principle that there are 13(123) ways.

Probability: The branch of mathematics known as probability deals with numerical expressions of the probability that an event will occur, or the probability that a statement will be true.

The probability of an event is a number between 0 and 1, with approximately 0 meaning improbability and 1 meaning certainty.

The probability of an event occurring increases with its probability. A simple example is tossing a fair (fair) coin.

Both outcomes (heads and tails) have equal probability, the coin is fair, heads are more likely than tails, there are no other possible outcomes, and either outcome has half the probability.

According to our question:

Let n be the maximum number of subsets of 5 elements that can be chosen from the first 14 natural numbers,

where at least 2 of the 5 digits are consecutive.

We created a block of two consecutive numbers ((1,2), (2,3), (13,14), etc.).

Now you can select this block in 13 different ways. You have to choose 3 numbers from the remaining 12 numbers.

So, from the multiplication principle, we know that we have 13 × (123).

The scenario where a restaurant gathers data about a new dish by providing free samples to parties of six or more is a sampling bias.

What is sampling bias?

Sampling bias occurs when some members of a population are systematically more likely than others to be chosen for a sample. In the medical world, this is known as ascertainment bias. Because it threatens external validity, specifically population validity, sampling bias reduces the generalizability of findings.

Sampling bias occurs when some people in a community being surveyed are purposefully placed to be chosen or not chosen over others. If a sample process consistently favors some results over others, it is said to be biased. Ascertainment bias particularly in biological areas)/ and systematic bias are other terms for sampling bias. Bias can be intentional, but it is frequently unintentional.

3. $1.05 each 5 at $3.90
4. 7.8 cents each $3.78 for 6
5. 63 cents each 1 for $1.58

Answers

1. 20 for $1.56 = A. 7.8 cents each

2. $3.78 for 6 =B. 63 cents each

3. For one dollar =C. 40 cents each

4. 5 at $3.90  = D. 78 cents each

5.  for $1.58  = E. $1.05 each

1.   20 for $1.56

Since cost of 20 items = $1.56

So, cost of 1 item =    1.56/20                          

                            =$0.078

1 dollar = 100 cents

So, $0.078= 0.078 × 100

                 =7.8 cents.

2. $3.78 for 6

Since cost of 6 items = $3.78

So, cost of 1 item = 3.78/ 6

                             =$0.63

1 dollar = 100 cents

So, $0.63 = 0.63 × 100 =63 cents.

3. 2 1/2 for one dollar

Cost of 2 1/2 = 5/2 = $1

So, cost of 1 item = 1/5/2

                            = 2/5

1 dollar = 100 cents

So, $2/5 =2/5 × 100

              =40 cents.

4. 5 at $3.90

Since cost of 5 items = $3.90

So, cost of 1 item = 3.90/5

                             =$0.78

1 dollar = 100 cents

So, $0.78 = 0.78 × 100

                =78 cents.

5. 1 1/2 for $1.58

Cost of  1 1/2 = $1.58

The rate of the slower car is 152 km/hr.

Given:

two cars leave towns 340 kilometers apart at the same time and travel toward each other. one car's rate is 18 kilometers per hour less than the other's. if they meet in 2 hours.

Let x be the rate of slower car.

We have two cars heading towards each other. They start 340 km apart and meet up 2 hours later. This means that they are traveling:

340 / 2 = 170 km/hr towards each other.

If the two cars were traveling the same speed, they'd both be going:

170 / 2 = 85 km/hr

We know that one car is traveling 18 km/hr faster than the other car. One way we can account for this is to  ± 9 km/hr to the average speed:

85 ± 9 = 94 , 76 km/hr

rate of slower car x = 84 - 9 * 2

The linear function is C(x) = 500 + 1.25x and the revenue function is R(x) = 3.50x.

What is a function?

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable

solution:

The linear function:

  C(x) =  1.25x + 500

For revenue function:

  R(x) = 3.50x

R(50) = 3.50(50)

         = $175

Using the C(x) and revenue function we can find the number of slushies and profit.

Thus, the linear function is C(x) = 500 + 1.25x and the revenue function is R(x) = 3.50x.

Answer: 8 mm

Step-by-step explanation:

      The altitude of the triangle can also be known as the "height" from the highest point as a straight line perpendicular to the opposite side (the "bottom" which is also known as the "base" of the triangle).

      This altitude makes two right triangles, so we will use the Pythagorean theorem to help us solve.

      a² + (6)² = (10)²

      a² + 36 = 100

      a² = 64

Therefore an equal number of people had relatively high and relatively low scores. This contradicts most having relatively high or low scores, or not drawing any conclusions about scores.

Answers

The probability that fewer than 22 customers in the sample buy coffee during their visit is 0.7764.

What is a normal approximation to the binomial?

When we utilize a continuous distribution (the normal distribution) to approximate a discrete distribution, we use the normal approximation to the binomial (the binomial distribution). The Central Limit Theorem states that if the sample size is high enough, the sampling distribution of the sample means approximates normality.

In a normal distribution with mean and standard deviation, the z-score of a measure X is given by:

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

Given, 55% of the customers buy coffee, p = 0.55

Sample of 35 customers, n = 35

mean  [tex]\mu[/tex] = np = 35*0.55 = 19.25

standard deviation, [tex]\sigma = \sqrt{np(1-p)}[/tex] = [tex]\sqrt{35*0.55*0.45}[/tex] = 2.94

So,  the probability that fewer than 23 customers in the sample buy coffee is

P(X < 22 - 0.5) = P(X < 21.5)

= [tex]P(\frac{X-\mu}{\sigma} < \frac{21.5-19.25}{2.94})[/tex]

= P(Z<0.765) = 0.7764

Hence, the probability that fewer than 22 customers in the sample buy coffee during their visit is 0.7764.
