Two dice are rolled. What is the probability that the sum of the numbers rolled is either 4 or 9? Express your answer as a fraction in lowest terms or a decimal rounded to
the nearest millionth.

Answers

Answer:

1/4

Step-by-step explanation:

There are 36 possible combinations. Of those 36, the ones that add up to either 6 or 9 are:

1+5, 2+4, 3+3, 4+2, 5+1, 3+6, 4+5, 5+4, 6+3

There are 9 combinations that add up to either 6 or 9. So the probability is 9/36, or 1/4.

Write an equation (any form) for the quadratic graphed below

Answers

Answer:

[tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

Explanation:

Since it is flipped and now extending to negative infinity, we make [tex]x^2[/tex] negative, so it is [tex]-x^2[/tex].

Lastly, there are a few shifts, it is shifted right once and up once.

To shift it right once, you would subtract a 1 from x directly: [tex]-(x - 1)^2[/tex]

To shift it up once, you would add 1 to the entire equation: [tex]-(x - 1)^2 + 1[/tex]

To account for the stretching, it would be: [tex]-\frac{1}{2} (x - 1)^2 + 1[/tex]

A set of 200 scores is normally distributed with a mean of 60 and . a standard deviation of 12. a, What are the z-scores corresponding to the. raw scores .of 76, 38; and 50

Answers

Answer:

Z scores for:

a) 76 = 1.33333

b) 38 = -1.83333

c) 50 = -0.83333

Step-by-step explanation:

Z score formula is:

z = (x-μ)/σ where

x is the raw score

μ is the population mean

σ is the population standard deviation.

Mean = 60

Standard deviation = 12.

a) 76

z = (x-μ)/σ

z = 76 - 60/12

z score = 1.33333

b) 38

z = (x-μ)/σ

z = 38 - 60/12

z score = -1.83333

c) 50

z = (x-μ)/σ

z = 50 - 60/12

z score = -0.83333

Please ASAP What is the remainder when x3−2x2−51x−108 is divided by x−2?

Answers

Answer:

[tex]-210[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=x^3-2x^2-51x-108[/tex]

And we want to find the remainder when it is divided by [tex](x-2)[/tex].

We can use the Polynomial Remainder Theorem, where if we have a function [tex]f(x)[/tex] divided by a binomial [tex](x-a)[/tex], then our remainder will be [tex]f(a)[/tex].

Here, our divisor is [tex](x-2)[/tex], so our a is 2.

Therefore, our remainder will be [tex]f(2)[/tex]. Let's substitute this for x. This yields:

[tex]f(2)=(2)^3-2(2)^2-51(2)-108[/tex]

Evaluate. Do the exponents:

[tex]f(2)=8-2(4)-51(2)-108[/tex]

Multiply:

[tex]f(2)=8-8-102-108[/tex]

Subtract:

[tex]f(2)=-210[/tex]

So, our remainder is -210.

And we're done!

Answers

Answer:

Step-by-step explanation:

in order to compare all the numbers, we have to express them all in the same form to compare them easily, we will choose to convert all of them to decimal form:

20% = 20/100 = 0.2

1/3 = 0.33333

3.4 x 10⁻¹ = 0.34

-5/2 = -2.5

comparing all these numbers, it is now clear that in decending order:

0.34 > 0.33333 > 0.2 > -2.5

3.4 x 10⁻¹ > 1/3 > 20% > -5/2
