A coin is flipped 50 times and lands on heads 28 times. What is the theoretical probability that the coin will land on heads on the next flip?.

Answers

Answer 1

The theoretical probability is 0.5

the practical probability is 0.5

Given, A coin is tossed 50 times, and it lands on heads 28 times. Theoretically, when a coin is tossed the probability of getting a head is 0.5 since in this question we tossed the same coin so the theoretical probability of the given question is 0.5. as per the given data, the Practical probability of getting a head is event happen divided by total events.

Practical probability = 28/50 = 0.56

Answers

Answer:

3:7

Step-by-step explanation:

To simplify the ratio 30:70, we find the greatest common divisor of 30 and 70, and then we divide 30 and 70 by the greatest common divisor. The greatest common divisor that you can use to simplify 30:70 is 10. This means the answer to ratio 30:70 simplified is: 3:7.

A salesman at a clothing store makes a sale to 30% of the customers he talks to, and wants to try out a new tecnique to see if he can change this rate. He decides to collect data for a few months on the percentage of customers he makes a sale to, and he is able to construct a 95% confidence interval of (.3095, .3275). Is there evidence at 5% significance that he has changed his average sales?

Answers

Answer:

Yes, we can conclude that average sales has changed.

Step-by-step explanation:

The null hypothesis, H0 : μ = 0.3

The alternative ; H0 : μ ≠ 0.3

The result of the 95% confidence interval of (.3095, .3275); This shows that the confidence interval is now between 30.95% and 32.75% ; since μ does not lie within the confidence interval value and the lower boundary of the confidence interval is > 30; we Can conclude with an evidence of 5% significance that his average sales as changed (increased).

We can reject H0 and conclude that μ > 0.3

At a recent charity event there was a range of admission charges:

Family (2 Adults + 2 Children)

Adult

Child (5 to 16 years)

Child under-5

$44

$14

$12

$10

Free

In addition it was possible to buy Family tickets before the event at the reduced cost of $40 per

family.

At the gate tickets to the value of $40 000 were purchased, and prepaid tickets added a further

$10000 to the total income. For every Family ticket sold on the day, 1 Adult, 1 Senior, and 3 Child

tickets were sold and 2 under-5 children were admitted free of charge.

How many people attended?

A

B

c

4400

4600

4650

5400

Answers

Answer:

5400

Step-by-step explanation:

Given data

Family (2 Adults + 2 Children) = $44

Adult = $14

Senior = $12

Child (5 to 16 years) = $10

Child under-5 = Free

At reduced price family buys ticket at = $40

Total prepaid ticket sold = $10,000

Value of ticket sold at the gate = $40,000

Determine how many people attended

first step : determine number of family that purchased the prepaid tickets

              = 10,000 / 40 = 250 families

∴  number people who booked prepaid tickets = 250 * 4 = 1000 people

Next step : Determine the number of families that booked the ticket at the gate

let the number of families = y

40,000 = 44 y + 12y + 3y * 10 + 14y + 2y *0

40,000 = y ( 100 )  hence y = 40,000 / 100 = 400

∴ number of people = 400 * ( 4 + 1 + 1 + 3 + 2 )  = 400 * 11 = 4400

Number of people whom attended = 4400 + 1000 = 5,400

If xy + 12 = 6x + 7, find y if x =5.

    1. This question is asking for the dilation, or division of each point by a factor of 3. This is shown in the results below:

         A' = (-4/3, -2/3)

         B' = (1/3, -1)

         C' = (2/3, -5/3)

         D' = (-1/3, 7/3)

    2. This question is asking the same thing as the previous question except for new points and a new scale factor. The results are shown below:

         A' = (3, 1)

         B' = (-2, -2)

         C' = (-4, 6)

         D' = (1, -4)

    3. This question is basically asking to multiply the area of the fence by two as shown with "extend the fence's range by a scale factor of 2." The results are shown below:

        A' = (4, 6)

        B' = (-6, 4)

        C' = (4, -4)

    4. This question is asking for the ratio of each side. Moreover, this means that the same side on both triangles must equal the same ratio. This is shown below:

         75/24 = 25/8

         60/18 = 10/3

The values of 25/8 and 10/3 are not the same, meaning that the scale ratio is not the same. These two triangles are NOT similar because of this.

    5. This question is asking the same thing as question 4. The results are shown below:

          10/5 = 2

          10/5 = 2

As these values are the same, these two triangles ARE similar because of how the larger triangle is multiplied by a scale factor of 2.

Dave drives a truck and can only drive 35 miles per day. If he drives 1,960 miles and gets paid $18 per day, how much money will he make?

Answers

Answer: $1008

Step-by-step explanation:

Since Dave can only drive 35 miles per day and he drives 1,960 miles, this means that the number of days he used for driving will be:

= 1960 / 35

= 56 days

Since he gets paid $18 per day, the amount that he will make will be:

= $18 × 56

= $1008

The height of the mural drawing is 9 inches while the length is 101.25 inches.

What is the scale factor?

You must specify the extent of the shape's enlargement when describing one.

The scale factor is the ratio of two dimensions such that one figure is large and another is small.

The scale factor is done due to the unpractical measurement of any figure.

Hight of the mural = is 12 feet

⇒ 12 × 12 = 144 inches.

Length of mural = 135 feet

⇒ 1620 inches.

Now,

She is using 3 cm for every 4 feet(4×12 = 48 inches)

Scale factor = 3/48 = 1 : 16

Now,

Length of mural drawing = 144/16 = 9 inches.

Height of mural drawing = 1620/16 = 101.25 inches.

Hence "The height of the mural drawing is 9 inches while the length is 101.25 inches".
