The probability of getting all three tosses to head is 1/8.

We have,

When a coin is tossed, there are two possible outcomes:

heads (H) or tails (T).

Since there are three tosses, the total number of possible outcomes.

2³ = 8.

The probability of getting heads on one toss is 1/2.

The probability of getting heads on all three tosses is the product of the probabilities of getting heads on each individual toss:

P(HHH) = P(H) x P(H) x P(H) = (1/2) x (1/2) x (1/2) = 1/8.

Therefore,

The probability of getting all three tosses to head is 1/8.

The candidate's campaign should sample 9604 voters for a 95% confidence interval with a margin of error of 1%.

To calculate the sample size needed for a 95% confidence interval with a margin of error of 1%, we can use the formula:

n = (z*σ/E)²

where:

n = sample size

z = z-score for the desired confidence level (95% corresponds to a z-score of 1.96)

σ = standard deviation of the population (unknown in this case, so we'll use 0.5 as a conservative estimate since we don't know the actual proportion)

E = margin of error (0.01 or 1%)

Plugging in the values, we get:

n = \((\frac{1.96*0.5}{0.01})^2\)

n = 9604

Rounding to the nearest voter, the candidate's campaign should sample 9604 voters for a 95% confidence interval with a margin of error of 1%.

Answer:

a=4  b = -16  c=9

Step-by-step explanation:

4(x-2)^2 -7

We need to FOIL out the (x-2) ^2

( x-2)^2 = (x-2) (x-2) = x^2 -2x -2x+4 = x^2 -4x+4

Replace this in the equation

4( x^2 -4x+4) -7

Distribute

4x^2 -16x +16 -7

Combine like terms

4x^2 -16x +9

a=4  b = -16  c=9

When 24 is divided by 849, the result would be 8/283 or 0.0283.

When 24 is divided by 849, the result would be a value that is less than 1.

This is because 24 is less than 849 and so 849 would be unable to go into it a single time.

The result would then be:

= 24/849

Simplifying it can be done by using the GCF of 3:

= (24 / 3) / (849 / 3)

= 8/283

= 0.0283

Answer:

Total gallon of fuel used = \(11.428\) gallons

Step-by-step explanation:

Given -

The total distance travelled by car in one gallon of gas = 21 miles

Total distance travelled each day = 48 miles

Number of days days in a week in which Candice drive is 5 days

Total miles travelled per week = \(48*5\) = 240 miles

Total gallon of fuel used = \(\frac{240}{21} = 11.428\) gallons

-14 is the value of the expression b - 3a at a =6 and b = 4.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given an expression b - 3a

For this expression given,

a = 6 and b = 4

Thus the value of expression at given values

=> b - 3a

=> 4 - 3 * 6

=>4 - 18

=> -14

The mean of the distribution of X = 2.4

The mean of a binomial distribution represents the average number of successes or occurrences of an event in a given number of trials.

In this scenario, the event is a college student preferring pizza over tacos, and the distribution follows a binomial distribution.

The mean of the distribution is calculated by multiplying the number of trials (sample size) by the probability of success.

In this case, the sample size is 8 students, and the probability of a student preferring pizza is 30% or 0.30.

Multiplying 8 by 0.30 gives us a mean of 2.4.

This means that, on average, out of the 8 randomly selected college students, we can expect approximately 2.4 students to prefer pizza.

The percent of change from 10 inches to 25 inches can be calculated by determining the difference between the two values, dividing it by the original value, and then multiplying by 100. The percent of change is 150%.

To find the percent of change from 10 inches to 25 inches, we first calculate the difference between the two values: 25 - 10 = 15 inches.

Next, we divide the difference by the original value (10 inches): 15 / 10 = 1.5.

To express this as a percentage, we multiply the result by 100: 1.5 * 100 = 150%.

Therefore, the percent of change from 10 inches to 25 inches is 150%. This indicates an increase of 150% from the original value of 10 inches to the final value of 25 inches.

The probability that a randomly selected student is interested in a "spinning-room" and also that they are a "graduate-student" is 0.428.

The total number of students that are surveyed is = 500 students,

Out of the 500 students surveyed, 41 are interested in a spinning room and are in year 1-2,

⇒ 75 are interested and are in year 3-4, and

⇒ 87 are interested and are graduate students.

So, the total number of students interested in a spinning room is

⇒ 41 + 75 + 87 = 203,

Out of these 203 students interested in a spinning room, 87 are graduate students.

So, probability that randomly selected student is interested in "spinning-room" and is a "graduate-student" is :

⇒ P(spinning room and graduate student) = 87/203,

⇒ P(spinning room and graduate student) = 0.428,
