Answer:

d. y = 5x/2 + 1, y = 5x/2 + 7

Step-by-step explanation:

Both lines have the same slope (5/2) , so they are parallel.

Answer:

[tex]x=16y^2-5[/tex]

Step-by-step explanation:

Lets solve for x.

[tex]\frac{\sqrt{x+5} }{4} =y[/tex]

Multiply both sides of the equation by 4.

[tex]\sqrt{x+5}=4y[/tex]

Eliminate the square root on the left side raising both sides of the equation to the power of 2.

[tex]\sqrt{x+5}^2=(4y)^2[/tex]

The square root and the exponent on the left side cancel out leaving us with

[tex]x+5=(4y)^2[/tex]

Distribute the exponent on the right side.

[tex]x+5=4^2y^2[/tex]

Simplify.

[tex]x+5=16y^2[/tex]

Subtract 5 from both sides.

The smaller of the numbers, given the ratio and the larger number, can be found to be 393.

Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.

The ratio is given such that it is 5 : 3 . What this means is that for every 3 of the smaller number, there is 5 of the larger number.

Given that the larger number is 655 therefore, the smaller number would be:

= ( Ratio of smaller number x Larger number ) / Ratio of larger number

Ratio of smaller number = 3

Ratio of larger number = 5

Answer: 126 marbles

Step-by-step explanation:

Let the marbles with Sam be x

so, marbles with Ravi will be 4x

we know total marbles are 630 which means

    x + 4x = 630

      x     =  126

so marbles with Sam & Ravi will be 126 & 504.

To make marbles equal each should have 315 marbles.

So, Ravi has to give 315 - 126 = 189 marbles to Sam.

The missing piece of information in the proof is that m ∠ DOA and m ∠ BOC are vertical opposite angles.

According to the equality's subtraction property, equality is unaffected by removing the same amount from both sides of an equation. When the same quantity or value is removed from both sides of an equation, the resultant difference is also identical on both sides.

Both the equality's addition and subtraction properties are related. The same integer added to or subtracted from both sides of an equation maintains equality on both sides.

To prove that m ∠ BOC = 90°.

Given that m ∠ AOB exists a right angle triangle.

Therefore; m ∠ BOC must also be equivalent to 90°.

Since m ∠ BOC and m ∠ AOB are right angles, it follows that m ∠ DOA and m ∠ BOC are also vertical opposing angles and, as such, are equal.

So, the fact that m ∠ DOA and m ∠ BOC are vertical opposing angles is the crucial piece of information missing from the proof.

The complete question is:

Given: AOB is a right angle

Prove: m BOC = 90°

Since AOB is a right angle, it is 90°. AOB is supplementary to BOC,

so m AOB + m BOC = 180°. By the substitution property of equality,

There is a 0.2209 = 22.09% probability that three students will arrive during a randomly chosen office hour.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin.

The coin is fair, thus the outcomes "heads" and "tails" are equally likely; the likelihood of "heads" is equal to the likelihood of "tails"; and because there are no other conceivable outcomes, the likelihood of either "heads" or "tails" is 1/2 (which is also an acceptable spelling).

by applying the same operation on both sides of the equation (so that the equality remains).

x + 38 = 79

to get "x = ...", we need to eliminate the "+ 38" in the x side.

The equation of the line is y = -5/2x + 5.

1. We know that the equation of a straight line is given by y = mx + c, where m is the slope of the line and c is the y-intercept.

2. We need to find the slope of line l. To find the slope, we can use the formula: m = (y2-y1)/(x2-x1). In this case, we have y2 = 1, y1 = 5, x2 = 2, and x1 = 0. Therefore, m = (1-5)/(2-0) = -4/2 = -2.

3. We now have the slope of line l, so we can find the equation of the line which is parallel to l and which passes through the point (3,0). To do this, we can use the formula y = mx + c, where m is the slope of the line and c is the y-intercept.

The point that is equidistant of the points (7, 3) and (13, -1) is (3.33, -9)

Remember the distance between two points (x₁, y₁) and (x₂, y₂) can be written as:

distance = √( (x₂ - x₁)² + ( y₂ -  y₁)²)

We want to find a point (x, y), that lies on the line y = -9 that is equidistant to  (7, 3) and (13, -1)

We can rewrite our point as (x, -9)

And the distances to the given points are:

distance = √( (x - 7)² + ( -9 - 3)²)

distance = √( (x - 13)² + ( -9 + 1)²)

These distances must be equal, (that is what equidistant means) so we can write:

√( (x - 7)² + ( -9 - 3)²) = √( (x - 13)² + ( -9 + 1)²)

Now we can remove the square root and simplify the equation:

(x - 7)² + ( -9 - 3)² =  (x - 13)² + ( -9 + 1)²

(x - 7)² + 144 = (x - 13)² + 64

x^2 - 14x + 49 + 144 = x^2 - 26x + 169 + 64

By finding the Greatest Common Factor we can conclude that the possible dimensions of the sports field are a width of 70 yards and a length 9-6d yards.

There are two theories needed to solve the problem:

Dimensions of an object are defined as a measure of length, width, or height extended in a certain direction.

The Greatest Common Factor (GCF) of two or more numbers is the largest number that can be evenly divisible by these numbers.

We can assume that the sports field is a rectangle since we know that:

- the width is at least 50 yards

- the area is (630-420d) yard square

To find the dimension of the sports field, we have to find the GCF of 490 and 210, by enumerating their prime factors and multiplying those factors both numbers have in common.

490 = 2 × 5 × 7 × 7

210 = 2 × 5 × 3 × 7

So the GCF is 2 × 5 × 7 = 70

This GCF depicts one of the dimensions of the sports field, which we denote as d₁.

By substituting the value of one dimension, the value of another dimension (d₂) can be obtained:

Area = d₁ x d₂

d₂ = Area / d₁

    = (630-420d) / 70

    = 9-6d

The correct expression for the given error interval is; 12.5 cm ≤ l ≤ 13.4

Error intervals are defined as the limits of accuracy when a number has been rounded or truncated. These error intervals are the range of possible values that a number could have been before it was rounded or truncated.

Now, we can also say that Error interval is the range of values (between the upper and lower bounds) in which the precise value could possibly be.

Now, since the precise value is given as 13 cm after approximation to the nearest centimeter, then the lower bound will be 12.5 because it is the lowest number that can be approximated to 13.

Answer:

16x feet

Step-by-step explanation:

A scale of 1/4" = 4' means that every 1/4 inch on the drawing or map represents 4 feet in the actual measurement. To find the actual length of a line on the drawing or map, you need to multiply the length of the line in inches on the drawing by the denominator of the scale, and then divide by the numerator of the scale.

The formula is:

Actual length = (length on the drawing or map x scale denominator) / scale numerator.

In this case, the length on the drawing or map is x inches, and the scale is 1/4" = 4'.

So the actual length is: (x inches x 4') / 1/4" = 16x feet

Therefore, the actual length of the line on the drawing or map is 16x feet.

The slope or gradient of a line in mathematics is a quantity that specifies both the direction and the steepness of the line. The slope of a line indicates its steepness. Slope is computed mathematically as "rise over run" (change in y divided by change in x). A slope is the steepness of a hill. The same is true for a line's steepness. The slope is defined as the ratio of the vertical change between two places, known as the rise, to the horizontal change between those same two points, known as the run.

To calculate the probability that the proportion of couples in the sample who are racially or ethnically mixed will be greater than .10, we can use a normal approximation to the binomial distribution.

First, we need to calculate the mean and standard deviation of the proportion of mixed couples in a sample of 200.

The mean is calculated as:

mean = n * p

where n is the sample size (200) and p is the proportion of mixed couples in the population (assumed to be .10).

So: mean = 200 * .10 = 20

The standard deviation is calculated as:

standard deviation = sqrt(n * p * (1-p))

where n is the sample size (200), p is the proportion of mixed couples in the population (assumed to be .10), and sqrt is the square root function.

So: standard deviation = sqrt (200 * .10 * .90) = sqrt (18) = 4.24

We can use the standard normal distribution to calculate this probability. The standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1. We can convert our random variable X to a standard normal variable using the following formula:

Z = (X - mean) / standard deviation

So: Z = (X - 20) / 4.24

To find the probability that X is greater than .10, we can use a standard normal table or calculator to find the probability that Z is greater than (X - 20) / 4.24

This probability is 0.48, so the probability that the proportion of couples in the sample who are racially or ethnically mixed will be greater than .10 is 48%.
