Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.

Answer:

1/26

Step-by-step explanation:

This is a case of joint probability.  We find the two probabilities separately and then multiply the results together:

P(odd number on cube) = 3/6 = 1/2; P(7 from a deck)) = 13/52 = 1/13

Then the desired joint probability is (1/2)(1/13) = 1/26

Note that the two events here are entirely separate and independent.

Which table shows a proportional relationship between x and y?
oksano4ka [1.4K]
The top one. Think about the difference between each one: X goes from 1 to 2 and Y goes from 5 to 10. Each number you go up, Y increases by 5. This means there is a proportional relationship.

The value of the definite integral / 212x – sin(x) dx / 122x-sin(x) is
blondinia [14]

Hi there!

\boxed{= 70 + cos(12) - cos(2) \approx 71.26}

\int\limits^{12}_{2} {x-sin(x)} \, dx

We can evaluate using the power rule and trig rules:

\int x^n = \frac{x^{n+1}}{n+1}

\int x = \frac{1}{2}x^{2}

\int -sin(x) = cos(x)

Therefore:

\int\limits^{12}_{2} {x-sin(x)} \, dx = [\frac{1}{2}x^{2}+cos(x)]_{2}^{12}

Evaluate:

(\frac{1}{2}(12^{2})+cos(12)) - (\frac{1}{2}(2^2)+cos(2))\\= (72 + cos(12)) - (2 + cos(2))\\\\= 70 + cos(12) - cos(2) \approx 71.26
