There are 18 girls and 12 boys in class. What is the probability that a new kid in senior class will be a boy?
valentinak56 [21]
There are 18 + 12 total students.

18 are girls and 12 are boys, since the total is 30 students, that's the amount of probable outcomes, and since there are 12 boys, that's the amount of favorable outcomes, thus

12/30 or 0.4, 0.4 * 100 is 40%.

Can someone explain and give an example of spurious correlation?
scoundrel [369]

Answer:

A spurious correlation wrongly implies a cause and effect between two variables. For example, the number of astronauts dying in spacecraft is directly correlated to seatbelt use in cars: Use your seatbelt and save an astronaut life!

Interesting correlations are easy to find, but many will turn out to be spurious. Three examples are the skirt length theory, the Super Bowl indicator, and a suggested correlation between race and college completion rates.

Solve for x the triangles In Each pair LMN~LRS <br> Please help quickly and show work pleasee
Gala2k [10]

Given:

\Delta LMN\sim \Delta LRS

To find:

The value of x.

Solution:

We have,

\Delta LMN\sim \Delta LRS

We know that the corresponding sides of similar triangles are proportional. So,

\dfrac{LM}{LR}=\dfrac{LN}{LS}

\dfrac{18}{2x-18}=\dfrac{30}{10}

\dfrac{18}{2x-18}=3

18=3(2x-18)

Using distributive property, we get

18=3(2x)-3(18)

18=6x-54

18+54=6x

72=6x

Divide both sides by 6.

\dfrac{72}{6}=x

12=x

Therefore, the correct option is A.
