Y = -3x + 13
Steps and the graph are on paper
Answer:
1) 18m²
2) 25cm²
Step-by-step explanation:
1)
- a = ½ × b × h
- a = ½ × 9 × 4
- a = ½ × 36
- a = 18m²
2)
- a = ½ × b × h
- a = ½ × 10 × 5
- a = 5 × 5
- a = 25 cm²
Answer:

Step-by-step explanation:
We have been an integral
. We are asked to find the general solution for the given indefinite integral.
We can rewrite our given integral as:


Now, we will apply the sum rule of integrals as:


Using common integral
, we will get:

Now, we will use power rule of integrals as:




We know that integral of a constant is equal to constant times x, so integral of 1 would be x.

Therefore, our required integral would be
.
Answer:
P( x = 2) = 0.4
Or 40%
Step-by-step explanation:
Given that wildcat has 0.5 probability of winning if they play nine times
Probability = possible outcomes ÷ required outcome
The required outcome = 9
Probability = 0.5
Let calculate the possible outcomes
Possible outcomes = 0.5 × 9 = 4.5 games
the probability that the Wildcats win two of the games will be
P( x = 2) = 2/4.5 = 0.44
Or 44%
