The trip from Carville to Nikpath requires $4\frac 12$ hours when traveling at an average speed of 70 miles per hour. How many h

KonstantinChe [14]

From the given speed and time, the distance of the trip can

be determined.

Correct response;

Number of hours the trip will take when traveling 60 mph is $\underline{5\frac{1}{4} \ hours}$

<h3>How is the time taken at a given speed calculated?</h3>

Given;

Time required for the trip from Carville to Nikpath = $4\frac{1}{2}$ hours

Average speed for the trip = 70 mph

Required;

The duration of the trip when traveling 60 mph

Solution;

Distance = Velocity × Time

Distance of trip = $\mathbf{4\frac{1}{2}}$ hour × 70 miles/hour = 315 miles

Duration of trip when traveling 60 mph is therefore;

$Time = \dfrac{315 \, miles}{60 \ miles/hour} = 5.25 \ hours = \mathbf{ 5\frac{1}{4} \ hours}$

Duration of trip when traveling 60 mph = $\underline{5\frac{1}{2} \ hours}$

A politician claims that a larger proportion of members of the news media are Democrats when compared to the general public. Let

kondaur [170]

Answer:

Null hypothesis: $p_1 -p_2 =0$ ,

Alternative hypothesis: $p_1 -p_2 > 0$

Step-by-step explanation:

Previous concepts

A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".

The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".

The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Solution to the problem

Some Notation

$p_1$ represent the proportion of the news media that is Democrat

$p_2$ represent the proportion of the public that is Democrat

On this case the claim that they want to test is: "That a larger proportion of members of the news media are Democrats when compared to the general public". So we want to check if the population proportion p1 is higher than p2, so this needs to be on the alternative hypothesis and on the null hypothesis we need to have the complement of the alternative hypothesis.

Null hypothesis: $p_1 \leq p_2$

Or $p_1 -p_2 \leq 0$

The null hypothesis can be on this way: $p_1 -p_2 =0$ , but is better put the complement of the alternative hypothesis.

Alternative hypothesis: $p_1 -p_2 > 0$

Here are 9 members on a board of directors. if they must elect a chairperson, a secretary, and a treasurer, how many different s

padilas [110]

Slot A = chairperson position
Slot B = secretary position
Slot C = treasurer position

There are 9 choices for slot A. After picking that person, there are 8 choices for slot B. Then 7 choices for slot C

Multiply those values out: 9*8*7 = 72*7 = 504

There are 504 ways to pick three people from a pool of nine.

Answer: 504

Note: order matters so this is a permutation. You can use the nPr permutation formula with n = 9 and r = 3 to get the same answer
