Answer C, .6
Remember the acronym SOHCAHTOA. In particular the theee letter we want to look at are CAH. The C means Cosine, aka. Cos, and the A means adjacent, which shares the same meaning as next to, and the H means hypotenuse, which the last two refer to sides of the triangle. Using the acronym CAH, it helps to remember the Cosine ratio Cos(x)=A/H, meaning the cosine of x equals the adjacent side over the hypotenuse, with x being the angle in focus. Once that’s known, we can create a simple equation. In this problem, your x is angle A, the adjacent side measures .6, and the hypotenuse measures .5, which make up every variable we need to solve for x.
Once that’s plugged into the equation described before, we get Cos(A)=.3/.5 (*you may want to put parenthesis around the decimals in the numerator and denominator, I dont recall for sure but that being there or not might give you a different answer, if it does then the answer using parenthesis is right). From here on, because the question only asks for the cosine of a, figuring it out is as simple as simplifying .3 over .5. .3 is 60% or .6 of .5 which makes .6 your answer, which is the way to figure it no calculator.
Happy to use my semester of pre trig and trig to some good.
I also think the answer is D, who else agrees with me? Btw, thank you for posting this question. I enjoy answering fun things sometimes.
Answer:
Step-by-step explanation:
You would need to figure out how many students, so for example let's say 24 students, if she gives each student half a cup (a pint) and there is 32 cups 32 x 2 = 64, Then you would want to divide 64 by 2, that would give you 32 pints. So each student gets 32 pints of juice. Could be different if the number of students weren't 24. You're welcome!
Answer:
The appropriate hypothesis set for Andraya to test is:
Step-by-step explanation:
The makers of the game claim that the wheel has an equally likely probability of landing on each section.
That is, the makers claim that the probability of earning the grand prize is:
Andraya has played the game for several months and believes that the grand prize occurs less often than the game makers claim.
At the null hypothesis, we test if it happens as often as the makers claim, that is, the proportion is 0.125. So
At the alternate hypothesis, we test if it happens less ofter than the makers claim, that is, the proportion is less than 0.125. So
The appropriate hypothesis set for Andraya to test is:
