tangare [24]3 years ago
3 0

Answer:

D

Step-by-step explanation:

So we want to figure out the measure of angle ?.

We already know that sides <em>opposite</em> and <em>adjacent</em> to the angle.

Therefore, we need to use tangent. Recall that tangent:

\tan(?)=opp/adj

Substitute 34 for the opposite and 48 for the adjacent:

\tan(?)=34/48

Divide (approximately):

\tan(?)=0.71

Take the inverse tangent of both sides:

?=\tan^{-1}(0.71)

So, our answer is D

And we're done!

A softball pitcher has a 0.675 probability of throwing a strike for each pitch and a 0.325 probability of throwing a ball. If th
Dafna11 [192]

Answer:

The probability that exactly 19 of them are strikes is 0.1504

Step-by-step explanation:

The binomial probability parameters given are;

The probability that the pitcher throwing a strike, p = 0.675

The probability that the pitcher throwing a ball. q = 0.325

The binomial probability is given as follows;

p(x) = _{n}C_{x}\cdot p^{x}\cdot q^{1-x}

Where:

x = Required probability

Therefore, the probability that the pitcher throws 19 strikes out of 29 pitches is found as follows;

The probability that exactly 19 of them are strikes is given as follows;

\binom{29}{19}(0.675)^{19}0.325^{10} = \frac{29!}{19!\times 10!}\times (0.675)^{19}\times 0.325^{10} = 0.1504

Hence the probability that exactly 19 of them are strikes = 0.1504

aev [14]

Answer: median and mean are the same

Step-by-step explanation:

The error committed by Michela is by saying

The median and mean are the same.

Because in statistics, we can't use mode to predict the median and the mean.
