A bag has 4 red marbles, 5 blue marbles, and 6 green marbles. What is the probability if choosing a red marble from the bag, not putting it back, and then choosing a green marble?
Answer: 4/35
Step-by-step explanation:
Number of red marbles = 4
Number of blue marbles = 5
Number of green marbles = 6
Total number of marbles = 4+5+6 = 15
When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.
Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:
= 4/15 × 6/14
= 24/210
= 4/35
simplify the algebraic expression!!
Answer:
[tex]\frac{y^{3}}{2z^{7}}[/tex]
Step-by-step explanation:
1. Move z^ − 3 to the denominator using the negative exponent rule b ^− n = 1/ b ^n
2. Multiply z ^4 by z ^3 by adding the exponents.
3. Cancel the common factor of 4 and 8
4. Cancel the common factor of x^2

The length of a rectangle is 1 m less than twice the width, and the area of the rectangle is 21 m?. Find the dimensions of the rectangle.
Answer:
length = 6
width = 3 1/2
Step-by-step explanation:
l = length
w = width
l = 2w-1
w(2w-1) = 21
2w² - 1 - 21 = 0
(2w - 7)(w + 3) = 0
w = 7/2 = 3 1/2
find 'l': l = 2(7/2) - 1 = 7-1 = 6

Answer:
2x^2+3x^4+1
Step-by-step explanation:
a trinomial is composed by three monomials.
So only A and B can be correct
the degree of a polynomial is the same of the monomial that compose it with the biggest degree
so the answer is B because the monomial with the biggest degree is 3x^4 (its degree is 4)

What is distribution in probability?By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.
E(X) = ∑( x ∗ P(x))
Given a probability histogram for a discrete random variable X.
We will drive the P(x) for every value of x.
P(X=1)=0.1
P(X=2)=0.2
P(X=3)=0.3
P(X=4)=0.25
P(X=5)=0.15
Putting these values in a summation equation to find E(x)
E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15
E(x) = 3.15
Therefore E(x) for the given histogram far random variable x will be 3.15.

(3x^2+7)+(2x^2-5x+10)
Answer:
5x² - 5x + 17
Step-by-step explanation:
(3x² + 7) + (2x² - 5x + 10)
Combine the like terms.
3x² + 2x² = 5x²
-5x does not have a like term, so there is no change.
7 + 10 = 17
Combine them, and the final equation is
5x² - 5x + 17.
Answer: 5x² - 5x + 17

Answer:

8*3+6=30
hope its right
Answer:
30
Step-by-step explanation:
So when they give us an anwser or a number that we can possibly plug in, its pretty simple. In our case we got the information that x=3. So if we ever see x in the expression, then we can plug in the information that they gave us into the expression. Let's view the expression, we can notice that there is once x that's being multiplied with 8. And since x is 3 we can do 8x3 and then add the 6 so the expression will look like 8(3)+6 which you solve and get 30.

Brenda's car averages 375 miles for each 15 gallon tank of gas. How many tanks of gas
will she use on an 1125 mile road trip?
Answer:
3
Step-by-step explanation:
We know that she uses one tank of gas every 375mi, so we can just divide.
1125 / 375 = 3
To check our work we can just multiply.
375 x 3 = 1125.
So she uses 3 tanks on the trip. I hope this helps :)

If the given lengths of a triangle are 16 and 10 which can NOT be the third side?
A.21
B.22
C.25
D.27
Answer:
D.27Step-by-step explanation:
This is because,
According to Triangle Inequality Property:
Measurement of any two sides of a triangle is always greater than the third side.
Here,
10 + 16 = 26 > 21
10 + 16 = 26 > 22
10 + 16 = 26 > 22
But,
10 + 16 = 26 < 27
Hence,
Option D: 27 can't be the measurement of the triangle.
