what is the value of underlined 5 fogit numbers?

Peter's number is 27

Step-by-step explanation:

You would need to multiply -6 with 11 to get -66. 11+16=27 this 27-16=11 so 11×(-6)=-66.

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.

Hence the linear and revenue functions are C(x) =  1.25x + 500 and  R(x) = 3.50x

If a set of exam scores forms a normal, symmetrical distribution with all measures of central tendency in the center of the distribution we can say about student's score that, about an equal number of students had relatively high and relatively low score.

A symmetrical distribution entails that the scores have the same number at a given distance above or below the average. 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.

Symmetrical distribution is evident when values of variables occur at a regular interval. In addition, the mean, median and mode occur at the same point.

Three of the many ways to measure central tendency are the mean, median and mode.

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

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

  (d)  -(√2)/2

Step-by-step explanation:

You want the exact value of the sine of an angle when its terminal side intersects the unit circle at (√2/2, -√2/2).

The coordinates of the point where the terminal side of angle θ intersects the unit circle are ...

  (cos(θ), sin(θ))

Comparing this to the given point, we find that ...

  sin(θ) = -√2/2

The ordered pair that is on the function y=f(2x+1)+3 is (-3/2, 6)

Here we know that for the function:

y = f(x)

And we know that the point (-2, 3) belongs to the function, this means that:

f(-2)= 3

Now we want to find a point on the function:

f(2x + 1) + 3

If we find x such that:

2x + 1 = -2

2x = -3

x = -3/2

Now we can evaluate the function in that value of x to get:

y = f(2*-3/2 + 1) + 3

y = f(-2) + 3

y = 3 + 3

y = 6

Then we have the point (-3/2, 6) on the function.

Step-by-step explanation:

so a^2+b^2=c^2

substitute and you get

a^2+6^2=10^2

a^2+36=100

a^2=100-36=64

a^2=64

a=8

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 + b² = c²

      a² + (6)² = (10)²

      a² + 36 = 100

      a² = 64

      a = 8

           The altitude of this triangle is 8 mm.

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

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,

100 – 1 = 99.

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

(1 – .997) / 2 = 0.0015

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.

Hence, 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.

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

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.

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.
