Answer:

8 and 15 are the lengths of the legs.

The tangent is the ratio of the lengths of legs.

In general, tan x = opp/adj

You have 8/15, so here 8 is the opposite leg and 15 is the adjacent leg.

Angle A is the right angle, so that is not it.

For which acute angle, B or C, is 8 opposite and 15 adjacent?

Answer: for angle B.

Therefore, 8/15 must be tan B.

What is the surface area of a coke bottle? <br>how do you figure it out?
svetlana [45]
Can or bottle? A can will be the calculation for the surface area of a cylinder which is A= 2 \pi rh+2 \pi  r^{2} if r is the radius of the circle on the top and bottom of the can and h is the height of the can. A can is basically two circles and a big rectangle. For a bottle I don't know there are too many components and no numbers to solve for that

Pls help me!!! I'm timed
Aleonysh [2.5K]
The domain is the x-axis and the range is the y-axis.

So the range of the function would be the Y values given.

So the range would be (3, 6, 9, 12, 15).

Researchers claim that 8% of people have blue eyes. Suppose the researchers' claim is true. Mrs. Greene has a Geometry class wit
vovikov84 [41]

Answer:

Probability that exactly 5 of them have blue eyes is 0.1165.

Step-by-step explanation:

We are given that Researchers claim that 8% of people have blue eyes. Suppose the researchers' claim is true. Mrs. Greene has a Geometry class with 40 students.

The above situation can be represented through Binomial distribution;

P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....

where, n = number of trials (samples) taken = 40 students

            r = number of success = exactly 5

           p = probability of success which in our question is % of people

                 having blue eyes, i.e; 8%

<em>LET X = Number of students having blue eyes</em>

So, it means X ~ Binom(n= 40,p=0.08)

Now, Probability that exactly 5 of them have blue eyes is given by = P(X = 5)

        P(X = 5) =  \binom{40}{5}\times 0.08^{5} \times (1-0.08)^{40-5}

                      =  658008 \times 0.08^{5}  \times 0.92^{35}

                      = 0.1165

                

Therefore, Probability that exactly 5 of them have blue eyes is 0.1165.
