The probability that at least 3 out of 9 randomly selected adult smartphone users use their smartphones in meetings or classes is approximately 0.8575.

To find the probability, we can use the binomial probability formula. Let's define a success as an adult using their smartphone in meetings or classes, with a probability of success (p) of 0.57.

We want to find the probability of getting at least 3 successes in 9 trials. This includes scenarios where we have 3, 4, 5, 6, 7, 8, or 9 successes. We can calculate the probability for each of these scenarios and sum them up.

Using the binomial probability formula:

P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9)

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where C(n, k) is the binomial coefficient, n is the number of trials, and k is the number of successes.

Calculating each term and summing them up:

P(X ≥ 3) = C(9, 3) * (0.57)^3 * (1 - 0.57)^(9 - 3) + C(9, 4) * (0.57)^4 * (1 - 0.57)^(9 - 4) + C(9, 5) * (0.57)^5 * (1 - 0.57)^(9 - 5) + C(9, 6) * (0.57)^6 * (1 - 0.57)^(9 - 6) + C(9, 7) * (0.57)^7 * (1 - 0.57)^(9 - 7) + C(9, 8) * (0.57)^8 * (1 - 0.57)^(9 - 8) + C(9, 9) * (0.57)^9 * (1 - 0.57)^(9 - 9)

Using the binomial coefficient values and simplifying:

P(X ≥ 3) ≈ 0.8575

The probability that at least 3 out of 9 randomly selected adult smartphone users use their smartphones in meetings or classes is approximately 0.8575. This means that in a random selection of 9 adult smartphone users, there is an 85.75% chance that at least 3 of them will use their smartphones in meetings or classes.

Approximately $334,728.87 should be set aside each year at the end of the period to accumulate $80,000 after 15 years with an interest rate of 10 percent.

To determine the amount that should be set aside each year to accumulate $80,000 after 15 years with an interest rate of 10 percent, we can use the Present Value-Future Value (PV-FV) tables.

First, let's find the Present Value Factor (PVF) for the given interest rate and time period. The PVF represents the value of $1 received or paid in the future, expressed in today's dollars.

From the PV-FV table for an interest rate of 10 percent and a time period of 15 years, we find the PVF to be 0.239.

Next, we divide the desired future value ($80,000) by the PVF to calculate the amount that should be set aside each year:

Amount to set aside each year = Future Value / PVF

= $80,000 / 0.239

≈ $334,728.87

Therefore, approximately $334,728.87 should be set aside each year at the end of the period to accumulate $80,000 after 15 years with an interest rate of 10 percent.

Answer:

y = 3

Step-by-step explanation:

We move all terms to the left:

26y-4-(68+2y)=0

We add all the numbers together, and all the variables

26y-(2y+68)-4=0

We get rid of parentheses

26y-2y-68-4=0

We add all the numbers together, and all the variables

24y-72=0

We move all terms containing y to the left, all other terms to the right

Answer:

ACD on edge2020

Step-by-step explanation:

The correct values function represented in the table is of y = acos(bx) are-

A function whose value increases algebraically as the independent variable increases algebraically across some range.

A function whose value declines as the independent variable rises over a specified range is referred to as a decreasing function.

Refer the attached table and graph.

Option (1) The function increases on the interval (π, 2π) is correct.

By graph, it is clear that the value of function is increasing between interval (π, 2π).

Option (2) The graph is compressed horizontally by a factor of One-half is incorrect.

Option (3) The frequency is StartFraction 1 Over 2 pi EndFraction is correct.

frequency = 1/time period

From the graph, time period in which function is repeating is 2π. thus frequency = 1/2π.

Option (4) The maximum value of the function is 6 is correct.

As shown in the graph, the range for the function goes up to 6.

Option (5) The period is π is incorrect.

The period for the the function is repeating is 2π not π.

Table 3

x | y

50 | 10

60 | 12

70 | 14

80 | 16

Step-by-step explanation:

x = time in minutes

y = distance travelled

Given that the bike travelled 7 miles after 35 minutes at a constant speed, the rate of change = [tex] \frac{7}{35} = \frac{1}{5} [/tex].

Thus, the table that represents the relationship between the time in minutes, x, and the distance the bike travles, y would have the same rate of change of ⅕.

Calculate the rate of change of each table using any two given pairs on the table:

Table 1: using (50, 10) and (55, 12)

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 10}{55 - 50} = \frac{2}{5} [/tex]

Table 2: using (60, 10) and (72, 12)

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 10}{72 - 60} = \frac{2}{12} = \frac{1}{6} [/tex]

Table 3: using (50, 10) and (60, 12)

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 10}{60 - 50} = \frac{2}{10} = \frac{1}{5} [/tex]

This table has the same rate of change.

Table 4: using (70, 10) and (84, 12)

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 10}{84 - 70} = \frac{2}{14} = \frac{1}{7} [/tex]

Table 3 represents the relationship between the time in minutes, x, and the distance the bike travles, y.

Step-by-step explanation:

The Finance charge for Zeke's bobsled purchase is $197.50.

To find the finance charge for Zeke's bobsled purchase, we need to calculate the total amount he will pay in monthly payments over the 2.5-year period and subtract the initial purchase price.

Given:

Purchase price (bobsled) = $1250

Down payment = $450

Monthly payment = $48.25

Duration of payments = 2.5 years

Step 1: Calculate the total amount paid in monthly payments.

First, we need to determine the total number of monthly payments Zeke will make over 2.5 years. Since there are 12 months in a year, the total number of payments will be 2.5 years * 12 months/year = 30 payments.

Next, we calculate the total amount paid in monthly payments by multiplying the monthly payment by the number of payments:

Total monthly payments = Monthly payment * Number of payments

Total monthly payments = $48.25 * 30 = $1447.50

Step 2: Calculate the finance charge.

The finance charge is the difference between the total amount paid in monthly payments and the purchase price:

Finance charge = Total monthly payments - Purchase price

Finance charge = $1447.50 - $1250 = $197.50

Therefore, the finance charge for Zeke's bobsled purchase is $197.50.

Answer:

10 m

Step-by-step explanation:

A square has all equal side lengths. If that is the case, the we have 4 sides that equal each other:

x + x + x + x = 40 m

4x = 40m

x = 10m

So each side is 10 m long.

Answer: Each side is 10 m

Step-by-step explanation: The perimeter is the total length of all the sides.

A square has 4 equal sides, so you divide the perimeter by 4.

40m÷4 = 10m

Step-by-step explanation:

Given pairs of side lengths that represent two sides of a triangle, you want an inequality representing possible lengths for the third side.

The triangle inequality requires the sum of the two shortest sides be greater than the longest side. Translated to this problem, it means the third side must have a length between the difference and the sum of the other two sides. For third side x, we require ...

  13 -8 < x < 13 +8

  5 < x < 21

  23.6 -11.5 < x < 23.6 +11.5

  12.1 < x < 35.1

  22 -15 < x < 22 +15

  7 < x < 37
