Answer and Step-by-step explanation:
(i) The solution for equation: 2(3x-3) - 5 = 2(x-3) + 15 is:
2(3x-3) - 5 = 2(x-3) + 15
6x - 6 - 5 = 2x - 6 +15
6x - 2x = - 6 + 15 + 6 + 5
4x = 20
x = 5
The solution x is a real number and equals 5.
(ii) Since the order of hot sauce that goes into the gumbo doesn't matter, use combination:
\(C^{10}_{3}\) = \(\frac{10!}{3! (10-3)!}\)
\(C^{10}_{3}\) = \(\frac{10.9.8.7!}{3.2.1.7!}\)
\(C^{10}_{3}\) = 120
There are 120 ways of picking 3 sauces out of 10.
(iii) Interest is calculated as:
interest = principal*rate*time
Principal is the value of the loan;
Rate is how much it will increase;
Time is for how long the loan will be taken. In this case, time is 9/12 since it was for months;
Interest = 3000 * \(\frac{11.75}{100}*\frac{9}{12}\)
Interest = 264.37
The interest the student will pay will be: $264.37.
Future Value = principal + interest
future value = 3000 + 264.37
future value = 3264.37
The future value for the student is $3264.37.
(iv) As shown in the image in the attachment, the sum of the equations equals 90:
2x + 30 + 2x + 40 = 90
4x = 20
x = 5
2x + 30 = 2.5 + 30 = 402x + 40 = 2.5 + 40 = 50The angles are 40° and 50°
Ayo runs a fairground game.In each turn, a player rolls a fair dice numbered 1 - 6 and spins a fair spinner numbered 1 - 12.It costs a player £1.40 for a turn.A player can win £6 or £3 as in the diagrams:If 216 people are to play, how much profit can Ayo expect to make?
Using the definition of expected value, it is found that Ayo can be expected to make a profit of £55.8.
The expected value is given by the sum of each outcome multiplied by it's respective probability.
In this problem:
The player wins $6, that is, Ayo loses £6, if he rolls a 6 and spins a 1, hence the probability is \(\frac{1}{6} \times \frac{1}{12} = \frac{1}{72}\).The player wins $3, that is, Ayo loses £3, if he rolls a 3 on at least one of the spinner or the dice, hence, considering three cases(both and either the spinner of the dice), the probability is \(\frac{1}{6} \times \frac{1}{12} + \frac{1}{6} \times \frac{11}{12} + \frac{5}{6} \times \frac{1}{12} = \frac{1 + 11 + 5}{72} = \frac{17}{72}\)In the other cases, Ayo wins £1.40, with \(1 - \frac{18}{72} = \frac{54}{72}\) probability.Hence, his expected profit for a single game is:
\(E(X) = -6\frac{1}{72} - 3\frac{17}{72} + 1.4\frac{54}{72} = \frac{-6 - 3(17) + 54(1.4)}{72} = 0.2583\)
For 216 games, the expected value is:
\(E = 216(0.2583) = 55.8\)
Ayo can be expected to make a profit of £55.8.

The calculated value of the degree measure of angle c is 16°
Finding the degree measure of angle cFrom the question, we have the following parameters that can be used in our computation:
The figure (see attachment)
The sum of angles in a triangle is 180 degrees
This means that

So, we have
x = 98
The measure of angle c is then calculated as
c + 2 * (180 - 98) = 180
Collect the like terms
c = 180 - 2 * (180 - 98)
Evaluate
c = 16

A batch of 150 iPads is inspected by choosing a sample of four iPads. Assume that 8 of the 150 iPads do not conform to specifications. How many samples of four contain exactly one non-conforming iPad
The given statement can be formulated as follows: A batch of 150 iPads is inspected by choosing a sample of four iPads. Eight of the 150 iPads do not conform to specifications.
How many samples of four contain exactly one non-conforming iPad?
Let's solve the given problem step by step.
Step 1: We have 8 non-conforming iPads and 142 conforming iPads in the batch of 150 iPads. We need to find the number of ways to choose 4 iPads that include exactly one non-conforming iPad.
Step 2: We choose one non-conforming iPad in 8 ways and choose 3 conforming iPads in 142C3 ways, where nCk is the number of ways to choose k objects from n distinct objects without regard to order.
Thus the total number of ways to choose 4 iPads with exactly one non-conforming iPad is given by:
=8 × 142C3
\(8 \times \frac{142 \times 141 \times 140}{3 \times 2 \times 1}\)

The relative frequency of heads is
A.reasonably close to
B.very different from
40%.
Mr. Clark's claim about the theoretical probability is likely to be
A.true
B.false
This means that the theoretical probability of tails is most likely
A.0.50
B.0.60
C.0.70
The relative frequency of heads is reasonably close to 40%.Mr. Clark's claim about the theoretical probability is likely to be false. This means that the theoretical probability of tails is most likely 0.60.
The relative frequency is the ratio of the number of times an event occurred to the total number of trials. In this case, the relative frequency of heads is 0.38 and tails is 0.62.The theoretical probability of an event is the number of favorable outcomes divided by the total number of possible outcomes.
Here, Mr. Clark claims that the coin is weighted so that the probability of heads is 40%. Therefore, the theoretical probability of heads is 0.40.However, the relative frequency of heads after 200 trials is only 0.38, which is reasonably close to 0.40. Hence, the relative frequency of heads is reasonably close to 40%.
Mr. Clark's claim about the theoretical probability of heads is likely to be false because the relative frequency of heads is less than the theoretical probability of heads (0.38 < 0.40).Therefore, the theoretical probability of tails is 1 - 0.40 = 0.60 because the coin is fair, so the probabilities of heads and tails should add up to 1. Thus, the theoretical probability of tails is most likely 0.60.

The given probability density function (pdf) is a valid pdf. The cumulative distribution function (cdf) can be calculated based on the pdf.
The probabilities of the random variable lying within specific intervals can be determined using the cdf. The value of the pdf at a specific point can also be calculated. Lastly, the 80th percentile of the distribution can be found using the cdf.
a. To show that the given function is a pdf, we need to ensure that it is non-negative over its domain and integrates to 1 over its entire range, which can be verified in this case.
b. The cdf, denoted as F(x), can be obtained by integrating the pdf from negative infinity up to x. In this case, since the pdf is constant between 1 and 6, the cdf will be a step function with a value of 0 up to x = 1, and a value of 0.2 from x = 1 to x = 6.
c. To find P(2 < X < 5), we calculate F(5) - F(2) using the cdf. Substituting the respective values, we get (0.2 * 5) - 0 = 1.
d. To find P(4 > X), we calculate 1 - F(4) using the cdf. Substituting the value, we get 1 - 0.2 = 0.8.
e. To find f(3), we simply substitute x = 3 into the given pdf, which gives a value of 0.2.
f. The 80th percentile corresponds to the value x for which F(x) = 0.8. From the cdf, we can see that F(x) = 0.2 for x ≤ 1, and F(x) = 0.2 for 1 < x ≤ 6. Therefore, the 80th percentile lies within the range 1 < x ≤ 6, specifically at x = 6.

comes with 4 different topping choices:
fudge, caramel, fruit, or plain. How many
unique ways can you order a frozen
yogurt? (You can only select one flavor of

To determine the number of unique ways to order a frozen yogurt with one flavor and one topping, we need to multiply the number of options for each category.
Starting with the yogurt flavor, there are three choices: vanilla, chocolate, and strawberry.
Next, for the toppings, there are four choices: fudge, caramel, fruit, or plain.
To find the total number of unique combinations, we can multiply the number of options for each category.
3 (yogurt flavors) x 4 (topping choices) = 12 unique ways to order a frozen yogurt.
So, there are 12 different ways you can order a frozen yogurt if you can only select one flavor of yogurt and one topping. This means that you can enjoy different combinations of frozen yogurt and toppings each time you order and never get bored.
However, it's always good to remember to keep a balanced and healthy diet even when enjoying sweet treats like frozen yogurt.

(Q2) The set of line segments _____ meet the requirements to form a triangle.8 cm4 cm3 cm
To form a triangle, the set of line segments must satisfy the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Therefore, we need to check if the given line segments 8 cm, 4 cm, and 3 cm meet this requirement.
We can start by checking if the sum of the two smaller sides (3 cm and 4 cm) is greater than the largest side (8 cm). 3 cm + 4 cm = 7 cm, which is less than 8 cm. Therefore, these three line segments cannot form a triangle.
In general, for a set of line segments to form a triangle, the largest side must be smaller than the sum of the other two sides. In this case, the line segment of 8 cm is too long compared to the other two sides, which makes it impossible to form a triangle.
In conclusion, there are no line segments that meet the requirements to form a triangle with lengths of 8 cm, 4 cm, and 3 cm.

what is a way that i can get 3x and 2x to cancel out in this problem? i need to get - 5y = -13 and + 15y = -3 alone.
problem:
3x + 5y = -13
2x + 15y= 3
Answer:
For 3x + 5y = -13 the answer is x= -13/3 + 5y/3
and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)
Step-by-step:
For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.
For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).
