Answer 1

Answer:

Use Close Call to practice two-digit addition or subtraction. The best math card games are simple at heart. To play Close Call, each player deals themselves four cards then determines how to arrange them so they make two two-digit numbers that add up as close as possible to 100 without going over.

A bag contains 4 g r e e n marbles, 8 b l a c k marbles, and 7 b l u e marbles. If a marble is drawn from the bag, replaced, and another marble is drawn, what is the probability of drawing first a g r e e n marble and then a b l u e marble

Answers

Answer:

[tex]P(Green\ and\ Blue) = 0.0776[/tex]

Step-by-step explanation:

Given

[tex]Green = 4[/tex]

[tex]Black = 8[/tex]

[tex]Blue=7[/tex]

Required

Determine the probability of selecting green then blue marble

This probability is represented as:

[tex]P(Green\ and\ Blue)[/tex]

And it is calculated using:

[tex]P(Green\ and\ Blue) = P(Green) * P(Blue)[/tex]

[tex]P(Green\ and\ Blue) = \frac{n(Green)}{Total} * \frac{n(Blue)}{Total}[/tex]

Total marble is:

[tex]Total = 4 + 8 + 7[/tex]

[tex]Total = 19[/tex]

So, we have:

[tex]P(Green\ and\ Blue) = \frac{4}{19} * \frac{7}{19}[/tex]

[tex]P(Green\ and\ Blue) = \frac{4*7}{19*19}[/tex]

[tex]P(Green\ and\ Blue) = \frac{28}{361}[/tex]

[tex]P(Green\ and\ Blue) = 0.0776[/tex] -- approximated

Hence, the required probability is approximately 0.0776

Answers

Answer:

Step-by-step explanation:

Set the two equations equal

8 + 1.25x = 10+.75x

Subtract .75x from each side

8 + 1.25x-.75x = 10+.75x-.75x

8 + .5x = 10

Subtract 8 from each side

8-8 + .5x=10-8

.5x =2

Divide each side by .5

.5x/.5 = 2/.5

a bag contains only red , yellow brown and green marbles
the probabilities of selecting each colour are below
red - 5x
green - 2x
brown - 3x
yellow - 4x
find the probability of selecting a green marble

Answers

Answer:

1/7

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur. this is expressed as;

Probability = Expected outcome/Total outcome

From the question, the total number of marbles is the total outcome

Total outcome = 5x + 2x + 3x + 4x

Total outcome = 14x

Since we are to find the probability of selecting a green marble, the expected outcome will be total number of green marbles which is 2x

Pr(selecting green marbles) = 2x/14x

Pr(selecting green marbles) = 1/7

Hence the probability of selecting a green marble is 1/7

What is the slope of the line through -2, one and two, -5 in the center of X, Y coordinate plane

Answers

Answer:

Answer:

A. -5(x + 2) = -4x - 12 - x + 2

Step-by-step explanation:

The equation that has infinitely many solutions will be the same on both sides.

A is the correct answer.

Simplify the equation by distributing -5 and adding like terms:

-5(x + 2) = -4x - 12 - x + 2

-5x - 10 = -4x - 12 - x + 2

-5x - 10 = -5x - 10

So, this equation is the same on both sides and will have infinitely many solutions.

A is the correct answer.

Answer:

A has infinitely many solutions

Step-by-step explanation:

Once you distribute A you get

-5x-10= -4x-12-x+2

Once you simplfy all that you get

-5x-10= -5x-10

You can check this by putting in a random number and both sides will be equal.

if f(x)=15x-7 then f^-1(x)

Answers

Hi!

So, we need to find the inverse of the function f(x) = 15x - 7.

To start, we must turn the f(x) into a y.

y = 15x - 7.

Now, we swap all the x variables for the y variables, and swap all the y variables for the x variables!

x = 15y - 7.

Now, we simply must work on isolating y. Assuming you know how to isolate a variable, we must do the steps below -

x = 15y - 7.

Add 7 on both sides.

x + 7 = 15y - 7 + 7.

We cannot add x and 7, as they are not like terms. So, they will remain like that, while the 7 on the right side of the equation is eliminated.

x + 7 = 15y.

Now we are going to divide both sides by 15, thus leaving y by itself.

= 15y / 15.

Since we cannot divide the left side of the equation by 15, it will remain as such. With the y variable completely isolated, our final inverse function will be:

= .

Hopefully, this helps! =)

What is the equation of the line that passes through the point (4,7) and has a slope of -1/4

Answers

Answer:

Step-by-step explanation:

since you are given the slope and a point....

use point slope formula y-y1 = m(x-x1)

y - 7 = -1/4 (x - 4)

then get that into the slope intercept form , use the formula y = mx + b as your target

y -7 = -1/4x +1

y = -1/4x +1 +7

y = -1/4x + 8 that's your answer
