mr_godi [17]

It is going to be 450 / 24 to get the amount of people in each class which will give 75 / 4. then the number of people who play golf is 75/4 * 4 which gives 75. so 75 people play golf

2 hour 40 min after a raft left pier A and traveled downstream, a motorboat left pier B and traveled upstream toward the raft. T

Answer:

3 km/h

Step-by-step explanation:

Let c represent the speed of the current in km/h, and t the time in hours after the raft leaves point A. 2 hours 40 minutes is 8/3 hours.

Distance = Speed × Time

The watercraft meet at a point 27 km upstream from B, so we have two equations involving these variables:

27 = 44 - ct

27 = (12-c)(t -8/3)

Equating these two versions of "27", we have ...

44 -ct = 12t -32 -ct +(8/3)c

76 = 12t + 8/3·c . . . . . add 32+ct

9t +2c = 57 . . . . multiply by 3/4

t = (57 -2c)/9 . . . .solve for t

Now, we can substitute this into the first of the above equations, after rearranging it to ...

ct = 17

c(57 -2c)/9 = 17

2c^2 -57c +153 = 0 . . . . multiply by 9, subtract the left side

c = (57-√((-57)^2 -4(2)(153)))/(2·2) = (57 -√2025)/4 = 12/4 . . . . quadratic formula

c = 3

The speed of the current is 3 km/h.

A simple random sample of 100 concert tickets was drawn from a normal population. The mean and standard deviation of the sample

alexandr402 [8]

Answer:

We accept the null hypothesis and the population mean is $120.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 100

Sample mean, $\bar{x}$ = $120

Alpha, α = 0.01

Sample standard deviation, s = $25

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 125\\H_A: \mu \neq 125$

We use two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = -2.0$

p-value one tail= 0.024

p-value two tail= 0.048

Conclusion:

Since the p-value for two tailed test is greater than the significance level, we fail to reject the null hypothesis and accept it.

Thus, the population mean is $120.
