Erin wants to raise her math grade to a 90 to improve her chances of winning a math scholarship. Her math average for the last marking period was an 75. What is the percent increase that Erin needs to improve her grade?​

Answers

Answer:

20%

Step-by-step explanation:

She needs to improve her average by the difference between her 2 grades

That difference is 15 points and is a 20% increase

Using the fromula for increase/ initial value x 100= new %

so (90-75)/75 x 100 = 15/75 x 100 which is then equal to 20%

Slope=-3/4

Step-by-step explanation:

The slope is the rise/run or y/x

Points given for A are (-4, 3), for B (4, -3)

The formula for slope is m=y^2-y^1/x^2-x^1

https://calcworkshop.com/graphing-linear-equations/slope-formula/

So we'll plug in the information given into the formula.

-4-4/3--3

-8/3+3

AB and CD

Answers

Answer:

Parallel = AB and CD

Perpendicular = EF and CD

Neither: GH and EF

Step-by-step explanation:

Parallel lines will go on forever without touching, they are aligned with each other.

Perpendicular lines intersect with 4 right angles

The Parallel lines are AB and CD and Perpendicular lines are  EF and CD.

It is required to find the solution.

What is line?

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

The given figure shown as four lines are given AB , CD ,EF , CD  ,GH and EF.

According to given question we have

Parallel = AB and CD

Perpendicular = EF and CD

Neither parallel nor perpendicular lines: GH and EF

Parallel lines are those lines that are equidistant from each other and never meet, no matter how much they may be extended in either directions

Perpendicular lines are lines that intersect at a 90-degree angle.

Therefore , the Parallel lines are AB and CD and Perpendicular lines are  EF and CD.

C. Translates the graph 4 units downwards

Step-by-step explanation:

The -4 is the y-intercept which brings the graph down four units

In the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 shows the translation of graph units downwards which is option c.

What is  function?

Function is relationship between two or more that are variables that are expressed in equal to form. In a function each value of x must have a corresponding value of y which is known as codomain of function.

How to find function?

In the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 decreases the value of function by 4 units and because the y axis is vertical line. So the value which is  -4 pulls the function downwards by 4 units and this process is known as translation.

Hence in the function f(x)=[tex]\sqrt{x}[/tex]-4, -4 shows the translation of graph units downwards which is option c.

The screen at Dallas’ AT&T Stadium is 175 feet wide. A movie theatre screen with similar dimensions is 40 feet wide with a screen area of 1,024 ft². What is the area of the screen at AT&T Stadium? Round to the nearest square foot.

Answers

Answer:

The area of the screen at AT&T Stadium is 4,480 square feet.

Step-by-step explanation:

Given that the screen at Dallas' AT&T Stadium is 175 feet wide, and a movie theater screen with similar dimensions is 40 feet wide with a screen area of 1,024 ft², to determine what is the area of the screen at AT&T Stadium the following calculation must be done:

40 = 1,024

175 = X

175 x 1,024 / 40 = X

179,200 / 40 = X

4,480 = X

Thus, the area of the screen at AT&T Stadium is 4,480 square feet.

Answers

Answer:

the probability when the IQ is lower than 136 is 0.9641

Step-by-step explanation:

Given that

The mean is 100

The standard deviation is 20

We need to find out the probability when the IQ is lower than 136

So,

z value equivalent to 136 = (136 - 100)  ÷ 20 = 1.8

Now  

p (z < 1.8) = 0.9641

hence, the probability when the IQ is lower than 136 is 0.9641

In philosophy  and psychology, a nativist is a person who believes in an innate understanding of particular concepts. This includes innate knowledge and ideas which occur at birth and are not acquired through learning and experience.

In United States history, a nativist is a person who opposes immigration of any kind which is deemed "undesirable" and who advocates for the exclusive interests of native-born citizens, often from longtime American families. Nativists disliked Catholics as well as immigrants and minorities.
