In the graph y will always be smaller than 1/5(x) - 4 in the inequality x−5y<20.

Mathematical expressions with inequalities on both sides are known as inequalities. In an inequality, we compare two values as opposed to equations. In between, the equal sign is changed to a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Olivia is chosen for the 12U softball team. What age is Olivia? Because it doesn't say "equals," you are unaware of Olivia's age. But since you already know Olivia's age should be below or equal to 12, you can write it as Olivia's Age 12. This scenario relates to inequalities in the real world.

First we will write the equation in the y-intercept form

y = mx + b

So,

⇒ x−5y<20    

⇒ x -5y - 20 < 20 - 20

⇒  x -5y - 20 < 0

⇒ x -5y - 20 - x +20 < - x +20

⇒ -5y < - x +20

⇒ 5y < x - 20

⇒ y < 1/5(x) - 4

Here slope is 1/5

So the graph is give below ↓↓↓

Thus, In the graph y will always be smaller than 1/5(x) - 4 in the inequality x−5y<20.

We have that the empirical rule to construct a 68% confidence interval can be expressed with the following general rule:

in this case, we have the following information:

then, the confidence interval with 68% of confidence is:

therefore, the confidence interval with 68% of confidence is (282,342)

Answer: (307,317)

Step-by-step explanation:

The population standard deviation is known (and is assumed to be normally distributed). Using the Empirical Rule, we know that approximately 68% of the data lies within one standard deviation of the mean. So, the confidence coefficient is zα2=1, approximately.The point estimate for the population mean, μ, is the sample mean, x¯=312.  The standard error for the sampling distribution is σx¯=σn√, where σ is the population standard deviation and n is the sample size. So, the standard error is σx¯=30n√. We did not list a decimal approximation because the instructions stated that only the final answer should be rounded. The error bound for the mean (EBM) is given by the formula EBM=zα2(σn√)=1(3030√). Again, we did not list a decimal approximation because the instructions stated that only the final answer should be rounded. Finally, we can calculate the confidence interval at the desired level of significance using the formula (point estimate−EBM , point estimate+EBM)(312−1(3030‾‾‾√),312+1(3030‾‾‾√))(307,317)

Vertical angles are always congruent - they always have the same angle measure. If one angle is 40 degrees, the vertical angle across from it will also be 40 degrees.

The angles that occupy the same relative location when a transversal cuts two or more lines are known as corresponding angles.

The figure's matching angle pairings are:

∠1 and ∠5 and ∠2 and ∠6 and ∠7 and ∠8

The matching angles are equivalent when the lines are parallel.

The pairs of angles on one side of the transversal and inside the two lines that make up a transversal that cuts two lines are known as the successive internal angles.

The further internal angles in the illustration above are:

∠3, ∠6, ∠4, and ∠5.

When a transversal cuts two parallel lines, supplemental pairs of subsequent interior angles result.

Pairs of angles on one line are generated when two parallel lines are sliced by a transversal, and these alternate internal angles are congruent.

The pairs of angles outside the two lines and on either side of a transversal that cuts two lines are referred to as the alternate external angles

∠1 and ∠7; ∠2 and ∠8;

When a transversal divides two parallel lines, the resulting alternate exterior angles are congruent.

Answer:

40 years old

Step-by-step explanation:

Define the variables:

Given Ryan is 93 years younger than Stacy:

⇒ r = s - 93

Given 9 years ago, Stacy's age was 4 times Ryan's age:

⇒ 4(r - 9) = (s - 9)

Substitute the first equation into the second equation and solve for s:

⇒ 4(s - 93 - 9) = (s - 9)

⇒ 4(s - 102) = s - 9

⇒ 4s - 408 = s - 9

⇒ 3s = 399

⇒ s = 133

Substitute the found value of s into the second equation and solve for r:

⇒ r = 133 - 93

⇒ r = 40

Therefore, Ryan is 40 years old now.

The missing measurement for z would be 6 yds.

The volume of the rectangular prism is the product of the base area and the height.

Given the volume of a rectangular prism is 24 yds cubed

Length of prism = z

Width of prism = 1 yds

Height of prism = 4 yds

The volume of the rectangular prism would be :

volume of the rectangular prism = Base Area × Height

volume of the rectangular prism = Length × Width × Height

Substitute the values in the above formula,

24 yds cubed = z × 1 × 4

Apply the multiplication operation, and we get

24 = 4 z

z = 24/4

z = 6 yds

Therefore, the missing measurement for z would be 6 yds.

Each equation 3x + 5 and 4x + 8 which is equivalent to each other is matched giving the value 4.

Equations with identical solutions or answers are said to be equivalent. It's common to compare linear equations to one another. When graphed, linear equations result in lines that are straight, have a slope, and have a y-intercept.

The characteristics that make linear equations linear are crucial in determining whether or not the equations will be equivalent when comparing linear equations. There are mathematical ways to determine whether the solutions to the equivalent equations are the same even though it may not initially appear that way.

To match the equation we need to find x first

3x + 5 = 4x + 8

⇒ 5 - 8= 4x - 3x

⇒ x = -3

Putting the value of x in respective equations

⇒ 3(-3) + 5 = 4(-3) + 8

⇒ -9 + 5 = -12 + 8

⇒ 4 = 4

Thus, each equation 3x + 5 and 4x + 8 which is equivalent to each other is matched giving the value 4.
