Answer:

Option (b) is correct.

The measure of angle y is 39°

Step-by-step explanation:

Given : A right angled triangle with some measurements.

We have to find the value of y.

Consider the given triangle,

Using trigonometric ratios,

We know tangent is the ratio of perpendicular to its base.

Mathematically written as

\tan\theta=\frac{Perpendicular}{base}

So, for given triangle, \theta=y

and for y, perpendicular is 8 and base is 10

Substitue, we have,

\tan y=\frac{8}{10}

Simplify, we have,

\tan y=\frac{4}{5}

Taking inverse of tan both side, we have,

\tan^{-1}(\tan y)=\tan^{-1}(\frac{4}{5})

y=\tan^{-1}(\frac{8}{10})

Simplify , we have,

y=38.65^{\circ}

Thus, the measure of angle y is 39°

So if 123 x 47= 5781, 123 x 0.47= 57.81, why? because its exactly like dividing the number by 100, instead of dividing in the end, we divided one of the multipliers :)

In New York City, 45% of all blood donors have type O blood. (Based on data from the Greater New York Blood Program). Find the p
quester [9]

Answer:

0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.

Step-by-step explanation:

For each donor, there are only two possible outcomes. Either they have type O blood, or they do not. The donors are selected randomly, which means that the probability of a donor having type A blood is independent from other donors. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In New York City, 45% of all blood donors have type O blood.

This means that p = 0.45.

Find the probability that 5 randomly selected blood donors in NYC all have Group O blood.

This is P(X = 5) when n = 5. So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 5) = C_{5,5}.(0.45)^{5}.(0.55)^{0} = 0.0185

0.0185 = 1.85% probability that 5 randomly selected blood donors in NYC all have Group O blood.
