Two hundred sixty students were surveyed on whether they prefer apple juice or orange juice. A table of relative frequencies is shown. How many more girls prefer apple juice than boys?

Answer:

1. 0.1635

2. 0.0026

Step-by-step explanation:

The computation of the probability in the following cases are as follows:

1.

Given that

Mean = 25 minutes

ANd, the standard deviation is 6.1 minutes

So here the z score would be

= (31 - 25) ÷(6.1)

= 0.98

Now the probability is

= P(Z>0.98)

= 0.1635

2. the z score would be

= (8 - 25) ÷(6.1)

= -2.79

Now the probability is

= P(Z<-2.79)

= 0.0026

Answer:

[tex]42^{o}[/tex]

Step-by-step explanation:

The square angle indicates it is a right angle, which is [tex]90^{o}[/tex]

[tex]90^{o}[/tex] - [tex]48^{o}[/tex] = [tex]42^{o}[/tex]

Answer:

For this problem you will be multiplying 3 probabilities together: P(#1 is blue)*P(#2 is blue)*P(#3 is blue). For the first probability, we just need to divide the number of blue marbles by the total number of marbles which would be 8/18. For the 2nd probability, we need to remember that we have already removed 1 blue marble so that the number of blue marbles remaining is now 7 and the total number of marbles is now 17 to give us 7/17. We would repeat this process to get the third probability and then multiply all the probabilities together.

Answer:

110%

Step-by-step explanation:

During final exam, 172 students visited the math lab in total.

4 out of 11 were male. It means, females are 11-4 = 7. So, the percentage of female students who visited the math lab is :

[tex]F=\dfrac{7}{11}\times 172\\\\F=109.4\%\\\\=110\%[/tex]

Hence, this is the required solution.

Taxable income:

Taxable income includes wages, salaries, bonuses, and tips, as well as investment income and various types of unearned income. ... Taxable income also includes earnings generated from appreciated assets that have been sold during the year and from dividends and interest income.

Tax rebates:

A tax rebate (or tax refund) is money you reclaim from HMRC if you've paid too much tax. Travel tax refunds are a great example. If you're paying your own way to get to temporary workplaces, you can claim back some tax on your travel expenses.

Tax threshold:

The tax threshold is the amount of income below which you do not pay any income tax. The filing threshold is the income amount below which you do not have to file a tax return to Sars.

Answer: (a) The mean and standard deviation of the average payout  that Joe receives from his 14,000 bets are $0.60 and $0.1602 respectively.

(b) The probability that Joe's average payout per bet is between $0.50 and $0.70 is 0.4647.

Step-by-step explanation:

Let X = average payout of a bet.

The mean of the random variable X is, μ = $0.60.

The standard deviation of the random variable X is, σ = $18.96.

The number of total bets made is, n = 14000.

Since n = 14000 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample mean.

Thus, the mean and standard deviation of the average payout  that Joe receives from his 14,000 bets are $0.60 and $0.1602 respectively.

Compute the probability that Joe's average payout per bet is between $0.50 and $0.70 as follows:

=P (-0.62 < Z < 0.62)

= P (Z < 0.62) - P(Z < -0.62)

= P (Z < 0.62) - [1-P (Z < 0.62)

= 2P (Z < 0.62) - 1

= (2 x 0.73237) - 1

= 0.46474

≈ 0.4647

Answer:

Stepby-step explanation:

The certain number = n

232 = 5n-28

232+ 28 = 5n -28 + 28

260 = 5n

260/5 = 5n/5

52 = n

Answer:

the denominator

Step-by-step explanation:

the top is numerator ans bottom is denominator

The number 6 is the denominator of the given fraction.

"A fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator.

The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole."

"A denominator is the part of a fraction that comes below the fractional bar. The denominator shows the total amount of parts that make up a whole. A fraction can be identified by a horizontal bar between two numbers. This bar or symbol is known as the fractional bar. The number on the top is known as the numerator, and the number below the fractional bar is known as the denominator."

For any fraction [tex]\frac{a}{b}[/tex], 'a' is the numerator and 'b' is the denominator.

The given fraction is [tex]\frac{2}{6}[/tex].

Here, the number 6 is the denominator of the given fraction.

Answer:

child's ticket =  4.75        adult ticket=10.75.

Step-by-step explanation:

The cost of an adult ticket is 6 more than that of a child ticket, so will be denoted by c+6. Now, we are told that the cost of four child tickets and two adult tickets is 40.50, so we can put this in an equation and solve for c:

(c+6)+(c+6)+c+c+c+c=40.50

6c+12=40.50

6c=28.50

c=4.75

Therefore the cost of a child's ticket (c) is 4.75 and the cost of an adult ticket (c+6) is 10.75.
