What is the additive inverse of -3.2?

Mathematics
1 answer:
Serhud [2]3 years ago
8 0

Answer:

3.2

Step-by-step explanation:

The additive inverse is what do we add to make it zero

x + -3.2 =0

Add 3.2 to each side

x+-3.2+3.2 = 0+3.2

x = 3.2

The additive inverse is 3.2

Mekhanik [1.2K]

Answer:

(B) No. A binomial probability model applies to only two outcomes per trial.

Step-by-step explanation:

The binomial probability is the probability of having x sucesses on n repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.

Since in our problem there are three possible outcomes, the binomial probability cannot be used.

The correct answer is (B)

(B) No. A binomial probability model applies to only two outcomes per trial.

Can u solve the answer
pickupchik [31]

Answer:

She needs 50 ft² of wood to cover the table

Step-by-step explanation:

You need to know the formula for area of a trapezoid, which is

A = (B1 + B2)h/s     (add the bases together, multiply by the height, then divide

                                by 2)

We are given B1 = 12, B2 = 8, and h = 5, so plug them in and simplify

A = (12 + 8)(5)/2

 

    A = (20)(5)/2

       A = 100/2

         A = 50 ft²

Evaluate for x=4 and y=-3 write in simplest form<br> 2y/x2
lorasvet [3.4K]

Hello from MrBillDoesMath!

Answer:

I think your formula  (2y/x2) is equivalent to

(2*y)/(x^2)      where x^2 means x-squared.

If so, then

(2*y)/(x^2) = (2*3)/(4*4) = 6/16 = 3/8

Thank you,

MrB

the first side of a triangle measures 4 in. less than the second side, the third side is 3 in. more than the first side, and the
Shtirlitz [24]
Start by representing the lengths of the three sides of your triangle:

first side:  x-4 (inches)
second side:  x (inches)
third side:  (x-4) + 3 (inches)

Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):

x-4  +  x  +  x-4  -3  =  15

3x-11=15
3x=26
x=26/3

Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).
