Answer:

Theoretical Probability: 33%

Experimental Probability: 25%

Which is greater?: Theoretical

Step-by-step explanation:

If two out of the six sections are labeled as 2, you'd have a theoretical probability of [tex]\frac{1}{3}[/tex] or 33% of winning.

Based on Stacy's experiment results, the pointer landed on a winning spin 30 out of the 120 times it was spun. This makes the experimental probability [tex]\frac{1}{4}[/tex] or 25% of winning.

In this scenario, the theoretical probability is greater than the experimental probability.

Hope this helps~!

Answer:

We have two independent events.

A number cube, with 6 possible outcomes.

A spinner, with 3 possible outcomes.

Each element in the combined sample space will be something like:

(outcome of the number cube, outcome of the spinner).

Then the number of possible outcomes in the sample size is equal to the product between the number of outcomes in each event.

Sample space size = 6*3 = 18.

Answer:

The answer is D. With all the 18 options.

The total finance charge for a $4,250 loan at 13. 25% interest compounded monthly for 24 months is $670.54.

What is Compound Interest?

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter.

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex]

A is the final amount, P is the Initial principal balance, r is the interest rate, n is the number of times interest is applied per time period, t is the number of time periods elapsed.

As it is given that the principal amount is $4,250 while the interest rate is 13.25% compounded monthly and the principal amount is taken for 24 months, therefore,

[tex]A = P(1 + \frac{r}{n})^{nt}\\\\A = 4,250(1 + \frac{0.1325}{12})^{24 \times 2}\\\\A = 5,531.54[/tex]

Now, the total amount that is needed to be paid is $5,531.54, while $4,250 was the principal amount therefore, the finance charge or the interest is,

Financial Charge = Final amount - Principal amount

Financial Charge = $5531.54 - $4861 = $670.54

Hence, the total finance charge for a $4,250 loan at 13. 25% interest compounded monthly for 24 months is $670.54.

The area of the sector which has a central angle of 5π/7 radians and a diameter of 5.6 in is 8.79 in².

The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.

It can be calculated as,

[tex]A_{sector}=\dfrac{d^2\theta}{8}[/tex]

Here, (d) is the diameter of the circle and (θ) is the central angle.

The central angle of the sector is 5π/7 radians and the diameter of the sector is 5.6 in.

Put the values in the above formula as,

[tex]A_{sector}=\dfrac{(5.6)^2\times5\pi}{8\times7}\\A_{sector}=\dfrac{(5.6)^2\times5\pi}{8\times7}\\A_{sector}=8.79 \rm \; in^2[/tex]

Answer:

Option (C)

Step-by-step explanation:

Quadratic parent function has been given as,

f(x) = x²

If we reflect this function across the x-axis and vertically stretched by a scale factor of 'k',

g(x) = -kx²

This quadratic function passes through a point (1, -4),

g(1) = -k(1)²

-4 = -k

k = 4

Therefore, the new function after transformation will be,

g(x) = -4x²

Option (C) will be the correct option.  

The function g(x) is [tex]\rm g(x) = -4x^2\\[/tex].

Given that,

The function g(x) is a transformation of the quadratic parent function,

[tex]\rm f(x) = x^2[/tex]

We have to determine,

What function is g(x)?

According to the question,

The function f(x) is a transformation of the quadratic parent function,

[tex]\rm f(x) = x^2[/tex]

In the given figure the function g(x) reflect across the x-axis and is vertically stretched by a scale factor of 'k',

Then, The function g(x) is,

[tex]\rm g(x) = -kx^2[/tex]

Therefore,

The quadratic equation passes through the point (1,4),

[tex]\rm g(x) = -kx^2\\\\g(1) = -k(1)^2\\\\-4 = -k\\\\k= 4[/tex]

Therefore,

The function g(x) is,

[tex]\rm g(x) = -kx^2\\\\g(x) = -4x^2[/tex]

Hence, The required function g(x) is [tex]\rm g(x) = -4x^2\\[/tex].

The probabilities for each case are:

There are 8 reservations for passengers that may go or not, such that the probability of arriving to the flight is P = 0.42, and the probability of not arriving is Q = 0.58

a) There will be overbooking if 7 or more passengers go to the flight, the probability that the 8 attend is:

P(8) = (0.42)^8

The probability that 7 attend is:

P(7) = 8*(0.42)^7*(0.58)

(where the factor 8 is because there are 8 permutations)

The total probability is:

P = P(8) + P(7) = 0.012

b) Will be empty seats if less than 6 people go.

The probability that exactly 6 of these people go to the flight is:

P(6) = (28)*(0.42)^6*(0.58)^2

Where there are 28 permutations, that is why we used that factor.

Then, the probability of having empty seats is:

P = 1 - P(6) - P(7) - P(8) = 0.937
