A single die is rolled. find the probability of rolling an eveneven number or a number less than 55.
sineoko [7]
The numbers less than 5 or even are {1, 2, 3, 4, 6}. This is 5 of the 6 possible numbers.

The probability of getting one of these on a single roll of a single die is 5/6.

Given the following cumulative frequency table, what is the mean of the distribution?
kipiarov [429]

Use the cumulative frequencies to figure out what the individual frequencies would be. Check out the attached image for the table of x values with their corresponding frequency (f) values. Note how the partial sums add up to the cumulative frequency values.

Once you know the frequency f values, multiply each x and f pair together in each row. The column labeled "x*f" represents each product. Afterward, add up everything in the x*f column to get the final answer 6.8

please help will give brainlest+30 points Snowy's Snow Cones has a special bubble gum snow cone on sale. The cone is a regular s
natali 33 [55]

Answer:

Hello There!

`~~~~~~~~~~~~~~~~~~~~~

If you subtract the volume of the sphere from the cone, you'll get the volume you can fill with flavored ice. Right?

Volume (sphere) = \frac{4}{3}\pi r^3

Volume(sphere) = \frac{1}{3}\pi r^2 . h

So that means, The volume left to put in flavored ice is :

Volume(sphere) = \frac{1}{3}\pi r^2h - \frac{4}{3}\pi r^2

So putting in the value for radius and height of the cone and radius of the sphere in the 2nd term will do the thing, I think.

.......

Okay, I think they didn't raise the power but wrote the exponent beside the number. It must be c. They wrote 32 so as to say 3^2 and wrote 0.553 to say (0.55)^3

So the answer is (C)

Hope this helped you. Brainliest would be nice!

Can someone please help me answer this? 2x2 + x -21​
Readme [11.4K]

Answer:

(x - 3)(2x + 7)

Step-by-step explanation:

Assuming you require the expression factorised.

Given

2x² + x - 21

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 21 = - 42 and sum = + 1

The factors are - 6 and + 7

Use these factors to split the x- term

2x² - 6x + 7x - 21 ( factor the first/second and third/fourth terms )

= 2x( x - 3) + 7(x - 3) ← factor out (x - 3) from each term

= (x - 3)(2x + 7) ← in factored form
