One way to show that a statement is NOT a good definition is to find a ____

Pleas help asap. Thank you A.53° B.39° C.37° D.27°

Viktor [21]

You will use the functions soh cah toa. you know that angle b is 90 so the other 2 angles have to add up to 90°. with the Pythagorean theorem we can get that cb is 12 feet. so we now have all side lengths and 1 angle. you can pick out that 53° will be your final answer after doing the basic functions!

A basketball player throws the ball up to another player who dunks it at the hoop. The ball leaves the hands of the first player

amid [387]

Answer:

The ball will take 1 sec

Step-by-step explanation:

∵ The distance from the ground when the ball leaves = 6 ft

∵ The distance from the ground when the ball catches = 10 ft

∴ The difference between two position = 10 - 6 = 4 ft

∵ s = ut - 1/2 at² ⇒ s is the distance , u is the initial velocity , a is acceleration of gravity and t is the time

∵ s = 4 feet , u = 20 feet/sec and a ≅ 32 feet/sec²

∴ 4 = 20t -32/2 t²

∴ 16t² - 20t + 4 = 0

∴ (4t - 4)(4t - 1) = 0

∴ 4t - 4 = 0 ⇒ t = 1 and 4t - 1 = 0 ⇒ t = 1/4

∴ The ball will take 1 sec to go from first player to the second player

Note: 1/4 sec is the time of the ball after leaves the position of the first player by 4 feet above the initial position.

X=6. y=5. 12×+3y please help me

IgorLugansk [536]

Answer:

Your answer: 87

Step-by-step explanation:

Since you are given what both variables are in the equation, this problem requires you to plug it in.

12(6)+3(5)= ?

You can either do this in a calculator, or do this one step at a time.

12(6)=72

3(5)=15

72+15=87

A ski resort gets an average of 2,000 customers per weekday with a standard deviation of 800 customers. Assume the underlying di

ladessa [460]

Answer:

0.62% probability that a ski resort averages more than 3,000 customers per weekday over the course of four weekdays

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
