Take the distance of thr graphed number and make sure you’re looking at the right quadrants
Answer:
The solution of given system is
Step-by-step explanation:
<u>Explanation</u>:-
Given 12t−2<−5t+36
<u>Step(i)</u>:-
Adding '5t' on both sides, we get
12t - 2 +5t < -5t +36 +5t
17t -2 < 36
<u>Step(ii)</u>:-
Adding ' 2' on both sides , we get
17t -2 +2 < 36 + 2
17t < 38
<u>Step(iii)</u>:-
Dividing '17' on both sides , we get
<u>Conclusion</u>:-
The solution of given system is
Answer:
Step-by-step explanation:
To find: inequality that describes the numbers x less-than 7
Solution:
An inequality compares two values a and b such that either one is less than i.e., a < b, greater than i.e., a > b, or simply not equal to another value i.e., a ≠ b. It describes a non-equal comparison two mathematical expressions.
Inequality that describes the numbers x less-than 7 is
Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4
∴ P(A or B)= 11/20
