Kaitlyn Has A Bag With An Equal Number Of Red, Yellow, And Blue Marbles. She Makes A Tree Diagram To

Answers

Answer 1

Answer:

6/9

Step-by-step explanation:

there are the possibility that she takes different colors six times in 9 different possible results

Answer 2

The probability that both marbles selected are different colors is 2/3.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Given that, Kaitlyn has a bag with an equal number of red, yellow, and blue marbles.

From tree diagram, we have {RY, RB, RR, YR, YB, YY, BR, BY, BB}

Here, the probability = 6/9

= 2/3

Therefore, the probability that both marbles selected are different colors is 2/3.

What value of w makes this multiplication sentence true? 28 · (824 + 514) = 28 · 824 + 28 · w

w =

Answers

Answer:

514

Step-by-step explanation:

First, we need to find the value of the non-variable side.

824+514 =1,338.

1,338 multiplied by 28 is 37,464.

So now we have :  37, 464 = 28* 824 + 28* w

28* 824 is 23,072.

And then we have, 23,072 * 28w.

Subtract 37,464 by 23,072on both sides, which is equal to 14,392 = 28w

Finally, divide 14,392 by 28 on both sides to get 514 = w

Therefore, w is 514.

Good luck mate, hope this helps.

Answer:514

Step-by-step explanation:

1338 x 28 = 37464

28 x 824 = 23072

37464 - 23072 = 14392

28 x 514 = 14392

On Monday, Dana groomed 15 dogs in 10 hours and Monique groomed 10 dogs in 8 hours. They each earn $12.75 for each dog groomed. Assuming that for the rest of the week Dana and Monique groom the same number of dogs per workday as they did on Monday, what will be the difference between their weekly earnings?

Answers

Answer:

$127.50

Step-by-step explanation:

On Monday Dana earned: 15*12.75 in 10 hours

For 40 hours Dana will earn: 15*12.75*(40/10) = $765

On Monday Monique earned: 10*12.75

For 40 hours Monique will earn: 10*12.75*(40/8) = $637.50

The difference between the weekly earnings is: $765 - $637.50 = $127.50.

4. Exponential

6. Quadratic Function

7. Absolute Value

8. Quadratic Function

For starters, the basic of a function is that for every input there is it's own [nonrepeating] output.

In mathematics, the term linear function refers to two distinct but related notions. We usually describe this as y=mx+b.

Exponential functions are a function of the form {f(x)=ab^{x}} where b is a positive real number, and the argument x occurs as an exponent.

Quadratic function, a quadratic polynomial, a polynomial of degree 2, or simply a quadratic numeral.

An absolute value function contains an algebraic expression within absolute value symbols (the value of a number is its distance from 0 on the number line.) To graph an absolute value function, choose several values of x and find some ordered pairs.

Functions -as stated before have one output for every input. They cannot repeat the same output as the horizontal line would.

Examine the table below. The table shows the cost to order pizzas at a local pizza shop. Determine how much it would cost to order 5 pizzas.

Pizza(n) 3 6 9 12 15
Cost (C) $9.99 $19.98 $29.97 $39.96 $48.95

Answers

It would cost $16.65

$9.99 divided by 3 is 3.33 so we know one pizza costs $3.33. So now if I multiply the 5 pizzas times the cost of one I get 5 x $3.33 = $16.65
it would cost $16.65
9.99 divided by 3 = 3.33
3.33 x 5 = 16.65

The inequalities h>42 and h<60 represent the height requirements for an amusement park ride, where h represents a person's height in inches.


Write a sentence or draw a sign or that describes these rules as clearly as possible.

Answers

Answer:

42<h<60

H is greater than 42 but less than 60, 42 is less that h and h is less than 60

(I don’t understand what the question is asking for so just correct me if I answered it incorrectly)

According to this inequality, the H must be at least 60 inches taller than 42 inches.

What is linear inequality?

According to the mathematical definition of inequality, neither side is equal. In mathematics, inequality occurs when a non-equal comparison between two expressions or numbers results from the relationship. In this expression, the equal sign "=" can be substituted for any of the inequality symbols greater than (>), less than (<), greater than or equal to (≥), less than or equal to (≤), or not equal to (≠). Mathematically can take many forms, including polynomial inequality, rational inequality, and absolute value inequality.

Given h > 42 and h < 60,

where h is height in inches,

the equation for inequality is,

42 < h < 60

which says that the height of a person should be more than 42 inches and less than 60 inches.

Hence the equation is 42 < h < 60, height should more than 42 inches and less than 60 inches.

Answer: Equation: E= 20H

Earning's after 15 hours: E= 20(15)

                                          E = 300

Step-by-step explanation:

The equation would be E =20H. E means her total earnings. 20 is how much money she earns per hour. H is how many hours she tutors. If you put it all together, you get E = 20H.

To solve how much she would get for 15 hours, plug in 15 for H so E=20(15). 20 x 15 = 300. Therefore, she will get $300 after teaching for 15 hours.
