Answer: How to add fractions and compare.

Step-by-step explanation:

When adding fractions, add the numerators first. If the numerator turns out to be more than the denominator, you have to turn it into a mixed fraction.

1 Divide-The quotient is the whole number, remainder is the numerator and the denominator stays the same.

Using the butterfly method, you can compare fractions.

For example: Which is greater? 4/7 3/5

Multiply it criss cross, you do 4 x 5=20 and7 x 3=21

20 is greater than 21

Hope this helps

dalvyx [7]

Answer:

a = 1/2 (b) (h)

Step-by-step explanation:

Use Pythagorean theorem for sub triangle on the left: 8^2 + h^2 = 22^2

Use Pythagorean again for sub triangle on the right: x^2 + h^2= 31^2

Find your base: 8+x=b

Find entire area: a = 1/2 (b) (h)

Suppose you are repeating a classic study of starfish and their impact on the ecosystems of tide pools. Using historic data coll

Travka [436]

Answer:

The probability of the number of starfish dropping below 3 is 0.0463.

Step-by-step explanation:

Let X represent the number of starfish in the tide pool.

X follows a Poisson distribution with mean 6.4.

The formula for Poisson distribution is as follows.

$P(X=x) = e^{-6.4} * [6.4^{x} / x!] when x = 0, 1, ...$

$P(X = x) = 0$ otherwise

We need to find the probability that the number of starfish in the tide pool drops below 3.

Therefore, the required probability is:

P(X < 3) = P(X = 0) + P(X = 1) + P(X=2)

$P(X < 3) = e^{-6.4} + (e^{-6.4}*6.4) + (e^{-6.4}*6.4^{2}/2)$

P(X < 3) = 0.00166 + 0.01063 + 0.03403

P (X < 3) = 0.0463
