Answer:

The slope of Car 1’s graph is 5 greater than the slope of Car 2’s graph.

Step-by-step explanation:

Given: A graph for car 1 goes through points (2, 50) and (4, 100). A graph for car 2 goes through points (2, 40) and (4, 80).

To find: Slopes of car 1 and car 2

Solution:

Slope of line joining points \((x_1,y_1),(x_2,y_2)\) is given by \(\frac{y_2-y_1}{x_2-x_1}\)

Slope of line joining points (2, 50) and (4, 100) = \(\frac{100-50}{4-2}=\frac{50}{2}=25\)

Slope of line joining points (2, 40) and (4, 80) = \(\frac{80-40}{4-2}=\frac{40}{2}=20\)

The slope of Car 1's graph is 25 and the slope of Car 2's graph is 20.

So,

the slope of Car 1’s graph is \(25-20=5\) greater than the slope of Car 2’s graph.

Answer:

There is a probability of 0 that the student plays both string and brass.

Step-by-step explanation:

Looking at the universal set, there are 40 students at this high school, 15 of which play string, 20 play brass, and 5 play neither (probably drummers).  Note how there is no intersection of A and B, which is the probability we are looking for.

Since there is no intersection in the universal set between subset A and subset B, you can say that there is a probability of 0 since there is no overlap between the two subsets.

Answer:

70

Step-by-step explanation:

x is present in the algebraic expression, therefore, option A is correct.- x is present in the expression, therefore, option B is correct.- x + y is present in the expression, therefore, option D is correct.

The given expression is: 3x[3(x + y)]^3x[3(x + y)]^3 × (x + 3)(x + y)

To simplify the given expression, we will first solve the expression within the brackets as follows:

(3(x + y))^3 = (3)³(x + y)³ = 27(x + y)³

Now, we will substitute the above value in the expression:

3x[3(x + y)]^3 = 3

x × 27(x + y)³ = 81x(x + y)³

Multiplying both terms of (x + 3)(x + y), we get:

(x + 3)(x + y)

= x(x + y) + 3(x + y) + 3y

= x² + xy + 3x + 3y + yx + 3y

= x² + 4xy + 6y + 3x

The final expression after substituting the value of 3x[3(x + y)]^3 and (x + 3)(x + y) is:

81x(x + y)³ × (x² + 4xy + 6y + 3x)

= 81x(x + y)³x² + 81xy(x + y) + 6xy + 27x(x + y)

= 81x³ + 189xy² + 81x²y + 6xy + 27x² + 81xy

Now, let's check which options are correct:- 3x is present in the expression, therefore, option A is correct.- x is present in the expression, therefore, option B is correct.- x + y is present in the expression, therefore, option D is correct.

Answer:

the answer would be 20.

Step-by-step explanation:

-

Answer:

\((((-2)^{4} )/(-4))-(2*(-3)*(8-4))\\\) = 20

Step-by-step explanation:

breaking into 2 parts:

calculate within parenthesis: \((((-2)^{4} )/(-4))\) = 16/(-4) = -4

calculate within parenthesis: (2*(-3)*(8-4)) = (2*(-3)*(4)) = -24

add and subtract (left to right): -4-(-24)=20

The decimal number 0.616 is \(1\frac{2}{5}\) percent of the number 44.

Let x be the \(1\frac{2}{5} \%\) of 44.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Now, \(1\frac{2}{5} \%\) can be written as \(\frac{7}{5} \%\).

So, \(\frac{7}{5} \%\) of \(44\) \(=x\)

\(0.014\times44=x\)

\(x=0.616\)

Therefore, the decimal number 0.616 is \(1\frac{2}{5}\) percent of the number 44.

The probability of rolling a 2 is 1/36.

The probability of rolling a 3 is 2/36.

The probability of rolling a 4 is 3/36.

The probability of rolling a 5 is 4/36.

The probability of rolling a 6 is 5/36.

The probability of rolling a 7 is 6/36.

The probability of rolling an 8 is 5/36.

The probability of rolling a 9 is 4/36.

The probability of rolling a 10 is 3/36.

The probability of rolling an 11 is 2/36.

The probability of rolling a 12 is 1/36.

Using these probabilities, you can answer your questions:

Probability of rolling a number bigger than 7 is the sum of the probabilities of rolling an 8, 9, 10, 11, and 12.

5/36 + 4/36 + 3/36 + 2/36 + 1/36 = 15/36 which reduces to 5/12

The probability of rolling a number not divisible by 6 is from the combinations 1,5 : 2,4 : 3,3 : 4,2 : 5,1 : and 6,6.

1 - 6/36 of possible combinations, which reduces to 1 - 1/6, which is reduced to 5/6.

Answer:

Step-by-step explanation:

Beth’s hair can be represented as 1 since everyone else is a fraction of her hair  so we just convert the other 2 fractions to make them have the same denominator

4x3/5x3=12/15

2x5/3x5=10/15

10 is less than 12 so carol has the shortest hair

Hopes this helps please mark brainliest

To help visualize, let's say Beth's hair is 15 inches:

Beth = 15"

Abbey = 4/5 * 15" = 12"

Carol =  2/3 * 15" = 10"

Carol has the shortest hair.

Alma was definitely correct to say that the tickets are $14 each.

The total amount in dollars the class have for tickets to the science museum

is $140.

The teacher writes as follows:

Alma says the tickets are $14 each.

Mohammed says that 14 students are going for the trip

The teacher divided 140 by 10. This means the number of student in the class is 10 not 14 as Mohammed enunciated.

The teacher divided the total amount available for the ticket($140) by the number of student in the class(10). Then the quotient ($14) is the amount in dollars which each student will pay for the ticket to the science museum.

Therefore, Alma was definitely correct.

Step-by-step explanation:

this is because there is only one side that is diffrent

Because lines a and b are parallel and lines e and f are parallel, the value of "x" is 82 degrees.

Parallel lines are coplanar infinite straight lines that do not cross at any point in geometry. Parallel planes are planes that never intersect in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance. Parallel lines are lines that are always the same distance apart in a plane. Parallel lines never cross. Perpendicular lines are those that connect at a straight angle (90 degrees). Parallel lines are lines in a plane that never intersect, no matter how far they are extended. The distance between the parallel lines is continuous since they never intersect.

Here,

Remember that vertical angles are generated by crossing lines that form two non-adjacent angles. These angles are congruent because they have the same vertex.

Take a look at the attached figure. Because lines "a" and "b" are parallel, the angles 82° and x° are vertical angles. As a result, they are congruent.

The value of "x" is 82 degree as lines a and b are parallel and lines e and f are parallel.

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

Given the equation x^2 = 2y.

The coordinates of the point are (4,1).We have to find the abscissa on the curve that is nearest to this point.So, let's solve this question:

To find the abscissa on the curve x2 = 2y which is nearest to the point (4,1), we need to apply the distance formula.In terms of x, the formula for the distance between a point on the curve and (4,1) can be written as:√[(x - 4)^2 + (y - 1)^2]But since x^2 = 2y, we can substitute 2x^2 for y:√[(x - 4)^2 + (2x^2 - 1)^2].

Now we need to find the value of x that will minimize this expression.

We can do this by finding the critical point of the function: f(x) = √[(x - 4)^2 + (2x^2 - 1)^2]To do this, we take the derivative of f(x) and set it equal to zero: f '(x) = (x - 4) / √[(x - 4)^2 + (2x^2 - 1)^2] + 4x(2x^2 - 1) / √[(x - 4)^2 + (2x^2 - 1)^2] = 0.

Now we can solve for x by simplifying this equation: (x - 4) + 4x(2x^2 - 1) = 0x - 4 + 8x^3 - 4x = 0x (8x^2 - 3) = 4x = √(3/8)The abscissa on the curve x^2 = 2y that is nearest to the point (4,1) is x = √(3/8).T

he main answer is that the abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The abscissa on the curve x^2 = 2y which is nearest to the point (4,1) is x = √(3/8).

The interquartile range (IQR) formula is: IQR = Q3 - Q1, where Q1 is the first quartile and Q3 is the third quartile of a dataset.

The interquartile range (IQR) is a measure of variability in a dataset that represents the range between the first quartile (Q1) and the third quartile (Q3). The first quartile (Q1) is the value that separates the lowest 25% of the data from the rest of the dataset, and the third quartile (Q3) is the value that separates the highest 25% of the data from the rest of the dataset.

Therefore, the IQR formula is simply the difference between the third and first quartiles: IQR = Q3 - Q1. The IQR is commonly used to identify outliers in a dataset, where any data points that fall outside of the range Q1 - 1.5IQR to Q3 + 1.5IQR are considered outliers.
