Answer:
Unit rate is $7 per pound.
6 pounds will cost $42
You can buy 10 pounds for $70
Step-by-step explanation:
28/4 = $7 --> Unit rate is $7 per pound.
7 × 6 = $42 --> 6 pounds will cost $42
70/7= 10 --> You can buy 10 pounds for $70
Answer:
The mode would be 45.
Step-by-step explanation:
The mode is 45 because a mode is the most repeated number in a set.
Answer:
A) 0.1538
Step-by-step explanation:
4 members are going to be chosen:
M1 - M2 - M3 - M4
We have to find the probability that for each member, one without experience is chosen. There is no replacents.
Initially, we have 15 students, of which 10 have none experience. So the probability that M1 is chosen as a student with no experience is .
Then, there are 14 students, of which 9 have no experience. So the probability that M2 is chosen as a student with no experience is .
For the third member, there are 13 students, of which 8 have no experience. So the probability that M3 is chosen as a student with no experience is .
For the last member, there are 12 students, of which 7 have no experience. So the probability that M4 is chosen as a student with no experience is .
What is the probability that none of the members chosen for the team have any competition experience?
This is
The correct answer is:
A) 0.1538
The exponent symbol when typing is ^. so I so rewrite this for you.
(15x^8 / 24y^5) / (4x^4 / 8y^2)
I assumed you meant 8y squared because you said 8 squared.
now when we divide by a fraction, we can actually multiply by it's reciprocal and get the same thing. The word reciprocal really just means flip it over. so:
(15x^8 / 24y^5) * (8y^2 / 4x^4)
let's reduce the coefficients ( the numbers in front of the x and y) to make it easier.
We have 15/24 which can be reduced to 5/8
and 8/4 which is 2/1
so:
(5x^8 / 8y^5) * (2y^2 / x^4)
multiply numerator and denominator
(10x^8y^2) / (8x^4y^5)
now reduce coeffient. 10/8 is 5/4
reduce x: x^8/x^4 is x^4
reduce y: y^2/y^5 is 1/y^3
now put together
5x^4 / 4y^3
so C
The sum of angles in a quadrilateral = 360 degrees.
Let the fourth angle be x:
Therefore: 60 + 95 + 150 + x = 360
305 + x = 360
x = 360 - 305
x = 55
Option B. I hope this helps.
