Answer: 2x = $90

Step-by-step explanation:

From the question, we are informed that Brady is selling candy bars for a school fundraiser to help pay for new sports uniforms and that he gets paid $2 for every candy bar he sells, and he made a total of $90 on Saturday.

The equation showing the number of candy bars Brady sold on Saturday goes thus:

Let the number of candy bars sold on Saturday be x.

Since each candy bar is sold for $2 and he made a total of $90, this means that the $90 gotten is the product of each candy bar and the amount sold which we represented by x. Therefore the equation will be:

2 × x = $90

2x = $90

We can further solve to get x.

2x = 90

x = 90/2

x = 45

That means 45 candy bars were sold.

Answer:

hi, so i belive the correct option to your question is:

2x = 90

Step-by-step explanation:

it just makes the most sense to me because 2x which could mean two times which in the equation it says he makes to dollars per candy bar sold, so it makes more sence for it to be 2x rather than 90x. and then it says he made a total of ninty dollars on saturday which is a key factor in solving this equation so think it would be 2x = 90$.

im really not sure if this logic makes sence, im not super good with algebra but i hope this helps you out.

Answer:

The answer is below

Step-by-step explanation:

Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.

The distance between two points on the coordinate plane is given as:

\(Distance=\sqrt{(x_2-x_1}^2+(y_2-y_1)^2 \\\\Therefore\ in\ triangle\ PQR:\\\\|QR|=\sqrt{(-2-(-2))^2+(4-0)^2}=4\\\\|PQ|=\sqrt{(-2-4)^2+(0-4)^2}=\sqrt{52}=2\sqrt{13} \\\\|PR|=\sqrt{(-2-4)^2+(4-4)^2}=6\)

In triangle STU:

\(|ST|=\sqrt{(-1-2)^2+(-2-(-4))^2}=\sqrt{13}\\\\|SU|=\sqrt{(-1-2)^2+(-4-(-4))^2} =3\\\\|TU|=\sqrt{(-1-(-1))^2+(-4-(-2))^2}=2\)

|QR| / |TU| = 4/2 = 2

|PR| / |SU| = 6/3 = 2

|PQ| / |ST| = 2√13 / √13 = 2

Hence:

|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|

Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.

Similar triangles may or may not be congruent

Triangles PQR and STU are similar by SSS theorem.

The vertices of triangle PQR are given as:

\(P= (4, 4)\)

\(Q= (-2, 0)\)

\(R = (-2, 4)\)

The vertices of triangle STU are given as:

\(S = (2, -4)\)

\(T = (-1, -2)\)

\(U =(-1, -4)\)

Start by calculating the side lengths of the two triangles, using the following distance formula

\(d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}\)

For triangle PQR, we have:

\(PQ = \sqrt{(4 --2)^2 + (4 -0)^2} = \sqrt{52}\)

\(PR = \sqrt{(4 --2)^2 + (4 -4)^2} = 6\)

\(QR = \sqrt{(-2 --2)^2 + (0 -4)^2} = 4\)

For triangle STU, we have:

\(ST= \sqrt{(2 --1)^2 + (-4 --2)^2} = \sqrt{13}\)

\(SU= \sqrt{(2 --1)^2 + (-4 --4)^2} = 3\)

\(TU= \sqrt{(-1 --1)^2 + (-2 --4)^2} = 2\)

Check if the side lengths of both triangles are similar, by dividing corresponding sides

\(k = \frac{PQ}{ST} = \frac{\sqrt{52}}{\sqrt{13}} = 2\)

\(k = \frac{PR}{SU} = \frac{6}{3} = 2\)

\(k = \frac{QR}{TU} = \frac{4}{2} = 2\)

Because the scale factors of the side lengths are the same, then both triangles are similar by SSS theorem.

Step-by-step explanation:

Interactions involving dummy variables can provide insights into the different effects of independent variables across categories.

1. Dummy variables are binary variables that represent categorical variables in a regression analysis. When interactions are included between dummy variables and other independent variables, it allows for differential effects of the independent variables based on the different levels of the categorical variable.

For example, let's consider a regression model to predict income based on education level and gender. We can include an interaction term between education level (represented by dummy variables for different levels) and gender. This interaction term allows us to examine whether the effect of education level on income differs between males and females. It helps capture any gender-specific differences in the relationship between education and income.

1.2 The linear probability model (LPM) is a common approach to estimate the probability of an event occurring using a linear regression framework. However, it has several problems:

1. The predicted probabilities from the LPM can fall outside the [0, 1] range: Since the LPM does not impose any restrictions on the predicted probabilities, they can sometimes exceed the valid probability range. This violates the assumption of probabilities being bounded between 0 and 1.

2. Heteroscedasticity: The LPM assumes constant error variance across the range of the predictors. However, in practice, the variability of the error term may change with different levels of the predictors, resulting in heteroscedasticity. This violates the assumption of homoscedasticity.

3. Non-linearity: The LPM assumes a linear relationship between the predictors and the probability of the event. However, this may not always be the case, and using a linear model can result in misspecification.

To remedy these problems, an alternative to the LPM is to use logistic regression or probit regression models. These models explicitly model the probability of an event occurring and address the issues mentioned above. They provide predicted probabilities that fall within the valid range of 0 to 1, account for heteroscedasticity, and allow for non-linear relationships between the predictors and the probability of the event.

Algebraic expression are the expression which consist the variables, coefficients of variables and constants.

The algebraic expression are used represent the general problem in the mathematical way to solve them.

Pete is making decorations for a dinner party. The instructions tell him to use 9 flowers for a medium-sized decoration which has 2 lilies, 1 rose, 3 carnations, 2 daffodils and 1 iris.

The ratio of daffodils to total flower is,

n=2/9.

To make a large decoration, Pete uses 36 flowers. Let suppose the daffodils flower he needs for this is x. Thus,

x=36*(2/9)

x=4*2

x=8

The rose flower is increased from 1 to 2. Thus, the total number of flower also be twice for decoration.

Flower=2*9

Flower=18

Now Pete uses 10 lilies instead of 2 which is 5 times the medium-sized decoration. Thus, the carnations to be needed is,

Carnations=3*5

Carnations=15

A regular polygon with angles that all measure 162 degrees has 20 sides.

Let's first consider a formula to find the measure of an interior angle of a regular polygon. We can use the formula:

Interior angle = (n-2) x 180 / n,

where n is the number of sides of the polygon.

If all angles of the polygon measure 162 degrees, then we can set up an equation:

(n-2) x 180 / n = 162

Multiplying both sides by n, we get:

(n-2) x 180 = 162n

Expanding the left side, we get:

180n - 360 = 162n

Subtracting 162n from both sides, we get:

The probability of either the system or the backup working properly is 1 - 0.02 = 0.98. Which is 0.02 x 0.02 = 0.0004 or 0.04%. Therefore, the probability that neither the system nor its backup is working properly at the end of the 30 days is very low, only 0.04%.

To find the probability that neither the primary computer system nor the backup system is working properly at the end of the 30-day period, we'll need to use the given probability of each system working properly (98%) and the fact that the systems work or fail independently.

Step 1: Find the probability of each system failing
Since each system has a 98% chance of working properly, the probability of it failing is 100% - 98% = 2%.

Step 2: Calculate the probability that both systems fail
Since the systems work or fail independently, we can multiply the probabilities of each system failing together:
2% (primary failing) x 2% (backup failing) = 0.02 x 0.02 = 0.0004

Step 3: Convert the probability to a percentage
0.0004 x 100% = 0.04%

Therefore, the probability that neither the primary computer system nor its backup are working properly at the end of the 30-day period is 0.04%.

The probability of at least one defective rivet in a seam requiring 27 rivets, assuming they are independently defective with the same probability, is approximately 68.3%.

To solve this problem, we can use the concept of probability and the binomial distribution.

The probability of a rivet being defective is denoted by "p". Since each rivet is defective independently of the others, the probability of a rivet not being defective (i.e., being good) is 1 - p.

The seam will need to be reworked if any of the 27 rivets is defective. Therefore, we want to calculate the probability that at least one rivet is defective.

The probability of at least one defective rivet can be found using the complement rule: subtracting the probability of no defective rivets from 1.

The probability of no defective rivets is given by (1 - p) raised to the power of 27 (since each rivet is independent).

So, the probability of at least one defective rivet is:

P(at least one defective rivet) = 1 - P(no defective rivets)

P(at least one defective rivet) = 1 - (1 - p)^27

Now, we can substitute any desired value for the probability of a defective rivet, "p," to calculate the probability of at least one defective rivet.

For example, if we assume a defective rivet probability of p = 0.05 (5%), the calculation would be as follows:

P(at least one defective rivet) = 1 - (1 - 0.05)^27

P(at least one defective rivet) ≈ 0.683

Therefore, with a 5% probability of a rivet being defective, the probability of at least one defective rivet in the seam is approximately 0.683 or 68.3%.

The equation 15s + 34t = 1 has infinitely many integer solutions, which can be represented as (s, t) = (-7/15 - 2k, k), where k is an integer.

To find integers s and t such that 15s + 34t = 1, we can use the extended Euclidean algorithm.

We start by applying the Euclidean algorithm to the original equation. We divide 34 by 15 and get a quotient of 2 and a remainder of 4. Therefore, we can rewrite the equation as:
15s + 34t = 1
15s + 2(15t + 4) = 1
15(s + 2t) + 8 = 1

Now, we have a new equation 15(s + 2t) + 8 = 1. We can ignore the 8 for now and focus on solving for s + 2t. We can rewrite the equation as:
15(s + 2t) = 1 - 8
15(s + 2t) = -7

To find the multiplicative inverse of 15 modulo 7, we can use the extended Euclidean algorithm. We divide 15 by 7 and get a quotient of 2 and a remainder of 1. We then divide 7 by 1 and get a quotient of 7 and a remainder of 0.

Working backward, we can express 1 as a linear combination of 15 and 7:
1 = 15 - 2(7)

Now, we can substitute -7 with the linear combination of 15 and 7:
15(s + 2t) = 1 - 8
15(s + 2t) = 15 - 2(7) - 8
15(s + 2t) = 15 - 14 - 8
15(s + 2t) = -7

Since 15 is relatively prime to 7, we can divide both sides of the equation by 15:
s + 2t = -7/15

To find integer solutions for s and t, we can set t as a parameter, say t = k, where k is an integer. Then, we can solve for s:
s + 2k = -7/15
s = -7/15 - 2k

Therefore, for any integer value of k, we can find corresponding integer solutions for s and t:
s = -7/15 - 2k
t = k

This means that there are infinitely many integer solutions to the equation 15s + 34t = 1, and they can be represented as (s, t) = (-7/15 - 2k, k), where k is an integer.

The probability of choosing all five white balls correctly can be calculated using the formula for combinations, where the order does not matter and the balls are chosen without replacement. The probability is given by:

P(Choosing all 5 white balls correctly) = (Number of ways to choose 5 white balls correctly) / (Total number of possible combinations)

The number of ways to choose 5 white balls correctly is 1, as there is only one correct combination.

The total number of possible combinations can be calculated using the formula for combinations, where we choose 5 balls out of 69. It is given by:

Total number of combinations = \({}^{69}C_5\)

Next, we need to calculate the probability of choosing the correct red ball from a bowl of 29 red balls. Since there is only one correct red ball, the probability is 1/29.

Finally, to find the likelihood of being the winner of the Powerball lottery, we multiply the probability of choosing all five white balls correctly by the probability of choosing the correct red ball:

((y-b)²/(y-b+1) = (y-b)(y-b)/(y-b+1) = (y-b)²/(y-b+1)

Now, we can combine the two terms in the equation by finding a common denominator:

(y-b)²/(y-b+1) + (y-b)/(y-b+1) = [(y-b)² + (y-b)]/(y-b+1)

Next, we can combine the terms in the numerator by factoring out (y-b):

[(y-b)² + (y-b)]/(y-b+1) = (y-b)(y-b+1)/(y-b+1)

Finally, we can cancel out the common factor of (y-b+1) in the numerator and denominator to get the polynomial:

(y-b)(y-b+1)/(y-b+1) = y-b

Thus, the probability that a quarter will land on a purple tile is 80%.

The total area of the floor is covered with 50 square-foot tiles. However, some of these tiles are not purple. We are not given the exact number of non-purple tiles, but we are provided with a table that lists some of them.

To find the probability that a quarter will land on a purple tile, we need to first determine the total area of the purple tiles.

If we assume that all the non-purple tiles are the same size as the purple tiles, then we can calculate the total area of the non-purple tiles using the information in the table.

The table lists five tiles that are not purple, and each of these tiles has an area of 2 square feet.

Therefore, the total area of the non-purple tiles is 5 x 2 = 10 square feet.

Subtracting the area of the non-purple tiles from the total area of the floor, we get the area of the purple tiles:
50 - 10 = 40 square feet

Therefore, the probability that a quarter will land on a purple tile is:
Area of purple tiles / Total area of floor = 40 / 50 = 0.8 or 80%

In other words, if you toss a quarter onto this floor at random, there is an 80% chance that it will land on a purple tile.
