Let's start making our expression.
Just take the number 40 and change it around.

That's a good start.
49 is equal to 7×7, or 7². 9 is equal to 3×3, or 3².
So we can also write this as

You can really do whatever you want with it as long as it's still 40, just make sure you've got an exponent there. Here's another example.
Answer:
a=0.62, b=7/9, c=10/9

SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses

Step 2: T-test analysis

Step 3: t-test with the significance level

Step 4: Comparing

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.
Answer:
Malcolm is showing evidence of gambler's fallacy.
This is the tendency to think previous results can affect future performance of an event that is fundamentally random.
Step-by-step explanation:
Since each round of the roulette-style game is independent of each other. The probability that 8 will come up at any time remains the same, equal to the probability of each number from 1 to 10 coming up. That it has not come up in the last 15 minutes does not increase or decrease the probability that it would come up afterwards.
Answer:
no, the plants will not be the same height.
Step-by-step explanation:
if you distribute 3 into the parenthesis (4x+2) it will give you 12x+6. if you distribute the other equation, 6 into the parenthesis (2x+2) it will give you 12x+12.
