Answer:

Polynomials are closed under addition and subtraction, which is fancy mathspeak that means that whenever we add or subtract two polynomials, we always get another polynomial. In that way, they behave a lot like the numbers you're probably already familiar with. Adding and subtracting:

Two integers gives you another integer
Two rational numbers gives you another rational number
Two real numbers gives you another real number

And it works the same with polynomials!

Felipe rented a truck for one day. there was a base fee of $14.95, and there was an additional charge of 87 cents for each mile

jeka94

Answer:

Felipe drove the truck for 1.26 miles

Step-by-step explanation:

Given :

Base fee = $14.95

Additional charge for each mile driven = 87 cents

Amount Felipe paid when he returned the truck = $124.57

To Find:

How many miles did he drive the truck =?

Solution:

Let number of miles Felipe drove be X

Then according to the question,

Base fare + 87(number of miles driven) = 124.57

Substituting the known values,

14.95 + 87(x) = 124.57

124.57- 14.95 = 87 x

109.62 = 8x

x = $\frac{109.62}{87}$

x = 1.26

Because the two distributions displayed below have similar shapes, they have the same standard deviation. true or false

sukhopar [10]

Since there is no files attached to see the shape of the distribution, let us just have it this way:

The statement, "Because the two distributions displayed below have similar shapes, they have the same standard deviation." is false. This is false because distributions having the same mean and standard deviation can have very different shape of distribution.

Is this relationship a function?

Oduvanchick [21]

Answer:

No, this is not a function.

Step-by-step explanation:

*Domain - {0,1,3,5}

*Range - {2,5,2,4.8}

Rule: A function is a special type of relation in which each value of the domain is paired with exactly one value of the range.

Since 0 pairs with both 2 and 5, this would not be a function.

Hope this helps!

The number of pencils in one pack = 6

The number pencil each student gets =2

To find:

The number of packs of pencils that is to be bought = ?

Solution:

To give all the 118 fourth grade students each 2 pencils , the total number of pencils needed will be

= > $118 \times 2$

=> 236 Pencils

We know that a pack contains 6 pencils, so the number of pack that has to be bought , in order to have 236 pencils will be

=> $\frac{ \text{total number of pencils}}{\text{ number of pencils per pack }}$

On substituting the values

=> $\frac{236}{6}$

=> 39.33

=> 40
