Answer:

the answer should be V = a³=2³=8cm³

Answer:

8cm

Step-by-step explanation:

The volume of a cube is length x width x height. If it a equal cube, all sides should be the same. Meaning that 2 x 2 x 2, equaling 8 would be the answer.

Answer:

increasing

Step-by-step explanation:

Answer:

1288 c m 3

Step-by-step explanation:

To work out volume, you just do the simple calculation of height x width x length. So what we need to do here is 6 x 7.5 x 22.9 =  

1212.5 c m 3  .

The decimal is a 5 so that is rounded up to give the nearest meter hence the answer to the question is  

1288 c m 3  .

The requried, tables that represent the same function are tables 1 and 3.

In mathematics, a function is a relationship between two sets of numbers, known as the domain and range, in which each element in the domain is associated with exactly one element in the range.

Here,
The tables that represent the same function are:

x|y

4|8

6|7

x|y

2|8

8|5

For two tables to represent the same function, they must have the same output for the same input. In the first table, input 4 gives output 8 and input 6 gives output 7. In the second table, input 2 gives output 8 and input 8 gives output 5. Therefore, these two tables represent the same function.

The other tables do not represent the same function, as they have different outputs for the same input values.

  3/8 pizza

Step-by-step explanation:

If 1/4 of the 4/4 of the pizza was gone, 3/4 remained. When that is split in half, each half is (3/4)(1/2) = 3/8 of the pizza.

Each gets 3/8 of the pizza.

What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability that you will have to deal with no more than 4 incidents be P ( x ≤ 4 )

Now , the success is one of your customers once every 9 weeks

So , p = 1/9

q = 1 - p = 8/9

x = 4

Number of trials n = 52 weeks

And , the probability that you will have to deal with no more than 4 incidents be P ( x ≤ 4 ) is

P ( x ≤ 4 ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

Substituting the values in the equation , we get

P ( x ≤ 4 ) = [ 52! / ( 48 )! 4! ] ( 1/9 )⁴( 8/9 )⁴⁸

On simplifying the equation , we get

P ( x ≤ 4 ) = 0.3008

P ( x ≤ 4 ) = 30.08 %

Therefore , the value of P ( x ≤ 4 ) is 30.08 %

Hence , the probability of no more than 4 incidents is 30.08 %

Answer:

A = 48

Step-by-step explanation:

In this equation, we can factor out the expression [tex](\frac{1}{7} )^x[/tex]. If we do so, the expression becomes:

[tex](\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)[/tex]

We can simplify to get:

[tex](\frac{1}{7} )^x(49 - 1)[/tex]

and get:

[tex]48*(\frac{1}{7})^x[/tex]

Therefore, A = 48

Answer:

D. 8​

Step-by-step explanation:

y varies jointly as x and z

y = k(xz)

-------------------------

Find k, the constant of variation

y = 12 when x = -2 and z=3

12 = k(-2 * 3)

12 = k(-6)

k = -2

-------------------------

find y when x is 4 and z is -1

using k = -2

y = -2(4 * -1)

y = -2(-4)

y = 8
