How to write in inqvality
Kitty [74]

Answer:

If you mean "How do I write an inequality?", the answer is COEFFICIENTxVARIABLE {any symbol} COEFFICIENTxVARIABLE >/< INTEGER

In other words, you should have something like this: -3x + 4v < 63

Or this: 51x - 16v > 11

Or anything along those lines.

A triangle has a side lengths of 3 centimeters, 5 centimeters, and 4 centimeters. Abe used converse of the Pythagorean Theorem t
fgiga [73]
No, Abe is incorrect.

If you don’t know which side is the hypotenuse, you have to try every possibility.

3^ + 4^ = 5^
25 = 25

The triangle is a right triangle. The side which is 5 cm long is the hypotenuse.

2 3/6 boxes and 1 2/3 boxes were recycled what is the total
Liono4ka [1.6K]
Since you are recycling the boxes you will be subtracting 2 3/6 and 1 2/3 since you’re a denominators you’re not mad she have to find a common denominator which would be six. So you have to do 2/2 x 2/3 = 4/6. So then you would do 3/6 - 4/6 = 1/6. Then you would subtract 1-2=1. Then you would do 1 + 1/6 = 1 1/6

So the answer is 1 1/6.

Answer:  g = -4  and   h =1     or   g= -1  and h = -2

Step-by-step explanation:

If two exponents have the same base and are multiplied together,  you will keep the base unchange and add the exponents.  

So looking at the equation, the base is 2 for both and they are raised to the powers  g and h, meaning that if  g and h are added together they have  to equal -3.

So find two numbers that their sum is -3.

For example,  -1 and -2 add up to -3, -4 and 1 add up to -3.

The probability that a student uses Smarthinking Online Tutoring on a regular basis is 0.31 . In a group of 21 students, what is
Ivenika [448]

Answer: 0.0241

Step-by-step explanation:

This is solved using the probability distribution formula for random variables where the combination formula for selection is used to determine the probability of these random variables occurring. This formula is denoted by:

P(X=r) = nCr × p^r × q^n-r

Where:

n = number of sampled variable which in this case = 21

r = variable outcome being determined which in this case = 5

p = probability of success of the variable which in this case = 0.31

q= 1- p = 1 - 0.31 = 0.69

P(X=5) = 21C5 × 0.31^5 × 0.69^16

P(X=5) = 0.0241
