Answer:

  Michael is wrong

Step-by-step explanation:

You want to know which student has misunderstood their grade computation, given the mean and median scores shown.

The mean of the test grades is their sum, divided by their number. The values shown for the mean grades are correct.

"Average" is another name for "mean." Thus the students' grade average will be the value of their mean grade, not their median grade.

Michael in incorrect in assuming that his median grade of 70% earns him a C in the class.

Answer:

Step-by-step explanation:

To make the race close, the length of the race should be 450 meters.

Here's the reasoning behind the answer:

Let's first calculate how long it would take for Emile to catch up to Henri, assuming Henri starts 45 meters ahead.

The time it takes Emile to cover the same 45-meter distance is 45/2.5 = 18 seconds.

During this time, Henri would have walked a distance of 1 x 18 = 18 meters.

So, after 18 seconds, Emile will have caught up to Henri and will be 27 meters ahead of him (45 - 18 = 27).

To make the race close, we want Henri to finish just a split second before Emile. So, we can assume that Henri will finish the race just as Emile catches up to him.

Let's call the total distance of the race "d."

So, Henri will walk d meters, while Emile will walk d + 27 meters (the 27 meters is the distance Emile has to walk after catching up to Henri).

We can set up an equation to solve for d:

d/1 = (d + 27)/2.5

Solving for d, we get:

d = 450

So, the race should be 450 meters long for Henri to win in a close race.

Answer:

She will earn $148.50 in overtime this week.

Step-by-step explanation:

First, you multiply 11 by 1.5. That gets you 16.5. So, for every overtime hour she works, she gets $16.50. Since she works 9 overtime hours, you multiply 16.5 by 9 to 148.5. So, she earns $148.50 for overtime this week.

The probability of drawing two red playing cards in succession from a preferred deck of playing cards is 1/4

The opportunity of drawing a red card on the first draw is 26/52 because there are 26 red cards out of a complete fifty-two playing cards.

Since the first card is replaced, the deck remains the same for the second draw. Therefore, the probability of drawing a red card on the second draw is likewise 26/52.

To calculate the probability of two unbiased occasions going on, we multiply the possibilities of each occasion together:

P(2 cards are red) = (26/52) * (26/52)

Simplifying:

P(2 cards are red) = (1/2) * (1/2)

P(2 playing cards are red) = 1/4

Therefore, the probability of drawing red playing cards in succession is 1/4.

To write an inequality that illustrates the weight limit for a group of adults and children on the fishing boat, let's assume that the letter a corresponds to the number of adults and the letter c corresponds to the number of children.

So, let's calculate:

The total weight on the boat by people corresponds to:

Now, let's add 200 pounds of equipment to this amount, and remembering that the total weight cannot exceed 1200 pounds, so we will find the following inequality:

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that situations can be represented with an integer​ that, when combined with the opposite of −5​, makes​ 0.

If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.

Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Answer:

the solution to the inequality is e > 25.

Step-by-step explanation:

To solve for e in the inequality -16+e>9, we can start by isolating e on one side of the inequality.

We can begin by adding 16 to both sides of the inequality to cancel out the -16:

-16 + e > 9

-16 + e + 16 > 9 + 16

e > 25

Answer:14

Step-by-step :The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(9/14, 2/7) = 14

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(914×11)+(27×22)=?

Complete the multiplication and the equation becomes

914+414=?

The two fractions now have like denominators so you can add the numerators.

Then:

9+414=1314

This fraction cannot be reduced.

Therefore:

914+27=1314

* Note: You said to help with two problems, but the screenshots you attached are two different images of the same question. I'm not sure whether or not that was intentional, but either way I thought I should let you know.

Your answer should be:

-5/14

The explanation is as follows:

Our equations for this question is -9/14 + 2/7. This includes two fractions: -9/14 and +2/7.

First things first, we have to find a common denominator. Once we find a common denominator, we must change either one or both fractions, which includes both the numerator and denominator of said fraction(s), to fit the new denominator. In this case, our denominators are 14 and 7. Finding a new denominator is quite simple. We simply have to double 7, or multiply 7 by 2, in order to get 14. Since we get 14 from 7 already, we do not have to change -9/14. Instead, we will multiply 2/7 by 2. Both the numerator and the denominator will be multiplied. 2 * 2 = 4. Our new numerator is 4. 7 * 2 = 14. Our new denominator is 14. This creates a new fraction of 4/14. When replacing the equation with the new fraction, we are left with -9/14 + 4/14.

Now that all of the fractions have the same denominator, we can properly combine them; this time around, we will be adding the two fractions (as can be seen with the addition sign in the equation). When adding fractions, the numerators are combined, but the denominators are not. In fact, that is why we must have the same denominator for all of the fractions. For this equation, we will add the numerators of -9 and 4 and bring the denominator over. -9 is a negative number, meaning that it is less than 0. 4, or +4, is a positive number, meaning that is greater than 0. Since -9 and 4 are on opposite sides of the spectrum, whichever number is either more negative or more positive will be victorious. -9 is more negative than +4, so our answer will be negative. -9 + 4 = -5. (You can just think about -9 and decrease the value by +1 four times to have the effect of +4.) -5 is our new numerator. After bringing the denominator over, we are left with the fraction of -5/14.

Simplest form is literally just the most simple form of a fraction. The simplicity of a fraction is determined by how low of a value its denominator is. You decrease the value of the denominator by dividing it. However, whatever you divide the denominator by, you must also divide the numerator by. You cannot have a decimal value for neither the numerator nor the denominator. For example, if you were to divide -5/14 by 2, you would get -2.5/7. Since -2.5 is a decimal, this fraction is illegitimate/not allowed. With that being said, there is nothing that you can divide -5/14 by to get a smaller denominator that is not a fraction. (If you want to check, you can divide -5/14 by anything from 2-14 - but preferably not 1 since you will end up with the same exact fraction.)

Therefore, -9/14 + 2/7 = -5/14.

P.S, Here's a quick little tip or piece of advice I edited in because I figured it may help somewhere along the line. You can always try to use a math calculator to help (you); and, yes, they do have explanations. Good luck!

Answer:

Let's start by using variables to represent the ages of the three people:

Let L be Liz's age.

Let D be Debbie's age.

Let F be Freya's age.

From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:

L = (2/3)D

We also know that Debbie's age is half of Freya's age, so we can write:

D = (1/2)F

To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:

F = 2D

Now we can substitute this expression for F into the equation for Liz's age:

L = (2/3)D = (2/3)(1/2)F = (1/3)F

So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Step-by-step explanation:

for the future look up '___ of a circle'

and enter the radius (if u are given the diameter divide it by 2)

Answer:

circumference = 37.68 (37.7 if you're rounding it)

Area = 113.04 (113.1 if you're rounding it)

Step-by-step explanation:

The formula for circumference is C=2πr (2 times pi times radius)

If the diameter is 12, the radius is 6.

2 x 3.14 x 6 = 37.7

The formula for area is A=πr2 (pi x radius to the second power)

The radius is 6. Six to the second power is 36.

36 x 3.14 = 113.04
