Cathy used a probability simulator to pull three colored marbles from a bag and flip a coin 50 times. The results are shown in the table below. Using Kathy’s simulation, what is the probability of pulling a blue marble in the coin landing tails up?

Answer:

a: -3n+1

b:-5n-2

Step-by-step explanation:

a: it is -3+1 because you can see that the sequence is going down by 3, so it is the 3 times table, but because the number is 4, and 4 is 1 more than 3, you put plus one at the end. :)

b: similar to the last, it's going down by five, but it is two less this time, so you put minus two instead.

Hope this helps :),

Answer:

4 terms

22x+33

Step-by-step explanation:

1. You count 1, 2, 3, 4 because there are no like terms to combine

2. you can use the distributive property to multiply the terms

(2x times 11) plus (3 times 11)

Answer:

4 terms; 22x + 33

Step-by-step explanation:

Expressions are made out of terms. A term can be a number, a variable, or a mixture of them. They are either added or subtracted.

In 5m2 - mn + 4n + 7, the terms are:

There should be 4 terms in the expression.

Answer:

y = e^x

Step-by-step explanation:

The fastest way to do this is to use a graphing calc or an online graphing platform and check to see which graph matches the one given.

The graph of the exponential function approaches zero as the value of x approaches negative infinity. Then the correct option is C.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The graph of the logarithm function approaches the infinity as the value of x approaches zero. So the given graph can not be a logarithm graph.

The graph of the exponential function approaches zero as the value of x approaches negative infinity. And at x = 0, the value of the function is 1.

Answer: [tex]y \leq \frac{1}{2} x+3[/tex]

Step-by-step explanation:

If a function has a positive slope, that means the y value is increasing with respect to x. As you go down the x-axis, the y value will continuously increase.

First you want to plot the two sets of coords that they gave you, or else you wont know what the line looks like. Or, you could visually do it in your head. We're going down -4 on the x-axis and down 1 on the y-axis. Then for our second coords, we are going to 0 on the x-axis, then up 3 on the y-axis.

You could plot this for yourself, but im going to do it in my head for simplicity. We also need to find the slope of this function in order for us to find the y-intercept. The slope is change in y divided by the change in x. Subtract the initial position from the final position.

3 - 1 = 2

0 - (-4) = 4

2/4 = 1/2

The new equation is:

[tex]y=\frac{1}{2} x+b\\plugin(0,3)\\3=\frac{1}{2} (0)+b\\b=3[/tex]

Everything is shaded below and to the right of the line. They said the line was solid, so that means less than or equal to, [tex]\leq[/tex]

Step-by-step explanation:

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

4 + 6 > 9

Yes, these lengths can form a triangle.

3 + 4 > 2

Yes, these lengths can form a triangle.

2 + 2 > 3

Yes, these lengths can form a triangle.

1 + 1 = 2

No, these lengths cannot form a triangle.

Answer:

D

Step-by-step explanation:

the formula is

a + b > c

a+ c > b

b+ c > a

The answer is D because

given lenght(D answer) A=1 , B=1, C=2

Thus, follow the formula.

a+b>c

1+1>2 ❌

a+c>b

1+2>1 ✅

b+c>a

1+2>1 ✅

we know that a+b>c is wrong, so, it cant form a triangle

Answer:

Equation of a line y = mx + c

m = slope

m = 2

Using point ( -4,3)

Equation of the line is

y - 3 = 2(x +4)

y - 3 = 2x + 8

y = 2x + 8 + 3

y = 2x + 11

Answer:

CD = 7

Step-by-step explanation:

If BC = 7 and ACB ≈ DCE, if you continue the line through BC, you'll see that the rest of it is CD, meaning BC = CD giving you the answer.

Answer:

Solution ⇒ 7

Step-by-step explanation:

Let us list the Given;

[tex]ACB = DCE,\\AC = 5 units,\\BC = 7 units[/tex]

Knowing that Δ ACB ≅ Δ DCE, by CPCTC we can consider the following;

[tex]AC = CD,\\BC = CE,\\AB = DE[/tex]

If we have to find the length of CD, given BD = 7 units;

Answer:

£ 14,430

Step-by-step explanation:

Costing Price = £13,000

Increase = 11% of 13000

=> 11/100 × 13000

=> 11 × 130

=> £ 1430

Increased Price = 13,000+1430

=> £ 14,430

Answer:

$2,800 and $6,400

Step-by-step explanation:

Aquí, sabemos que hay un 20% de descuento en compras.

Entonces, para una persona que compró cosas por valor de $ 3,500, el monto que debe pagar será; 20/100 * 3500 = $ 700

Entonces, la cantidad a pagar = 3500-700 = $ 2,800

Para la persona que compró $ 8000, monto a pagar = 20/100 * 8,000 = $ 1,600

Cantidad a pagar = 8000-1600 = 6400

Answer:

first we will check if the coordinate (5,4) is a solution:

you fill in only the X-coordinate (or the y-coordinate). I fill in 5 for X:

y-4 = 7(5-6)

now we have to work this out like:

y-4 = 7 • -1

y -4 = -7

y = -3 if the coordinate was the solution for the y-coordinate the answer should be 4 but it isn't so coordinate (5,4) isn't a solution.

the same goes for coordinate (6,5):

y-4 = 7 (6-6)

y-4 = 0

y = 4 if the coordinate was the solution for the y-coordinate the answer should be 5 but it isn't so coordinate (6,5) isn't a solution.

so the answer is neither

Answer:

Neither

Step-by-step explanation:

Simplify the given equation.

y - 4 = 7(x - 6)

y - 4 = 7x - 42

y = 7x - 38

Now, take the point (5, 4) and test to see if this is a solution.

y = 7x - 38

4 = 7(5) - 38

4 = 35 - 38

4 ≠ -3

Since that point did not prove to be true, answer choices A and C are cancelled out.  Take point (6, 5) and test it.

y = 7x - 38

5 = 7(6) - 38

5 = 42 - 38

5 ≠ 4

Neither points provide a solution so D is the answer.

Answer:

the answer should be D

Step-by-step explanation:

I hope this will help you:)

Answer:

1.092 x 10^8

Step-by-step explanation:

(4.2 x 10^3)(2.6 x 10^4)

Multiply the numbers

4.2* 2.6 =10.92

Add the exponents

10^3 * 10 ^4 = 10 ^(3+4) = 10^7

10.92 * 10^7

But this is not scientific notation, there can only be one digit in front of the decimal

Move the decimal one place to the left and add one to the exponent

1.092 * 10 ^(7+1)

1.092 x 10^8

​

1 pound = 1.62 dollars.

Multiply total pounds by 1.62 for total dollars.

650 x 1.62 = $1,053
