Both descriptive and inferential statistics rely on the same set of data. Descriptive statistics rely solely on this set of data, whilst inferential statistics also rely on this data in order to make generalisations about a larger population.

the numbers 2-12 are written on cards and placed in the bag.what is the probability of picking an even number then replacing it

lorasvet [3.4K]

We have the cards numbered as 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12.

Sample number is, n(S)=11.

We pick a card and want to get even number like 2, 4, 6, 8, 10, and 12.

Probability of picking an even number would be :-

P(even numbers) = $\frac{6}{11}$

Now we replace the card and want to get a 7 in second attempt.

Probability of picking a 7 would be :-

P(number 7) = $\frac{1}{11}$

Now Probability of this event = P(even numbers) × P(number 7)

Probability = $(\frac{6}{11} )(\frac{1}{11} ) = \frac{6}{121}$

So final answer is $\frac{6}{121}$ .

M WXZ=81°, and m 2 is 23° more than m 1. Find m 1.

BaLLatris [955]

$\begin{gathered} m\angle1+m\angle2=m\angle WXZ \\ m\angle1=m\angle WXZ-m\angle2 \\ m\angle1=81-m\angle2 \end{gathered}$

Besides, we have that

$m\angle2=23+m\angle1$

If we replace this equation in the previous one, we have

$\begin{gathered} m\angle1=81-(23+m\angle1) \\ m\angle1=81-23-m\angle1 \\ 2m\angle1=58 \\ m\angle1=\frac{58}{2} \\ m\angle1=21 \end{gathered}$

Then the angle 1 has measure 21 degrees.

Eveloped By An Engine With A Displacement Of 220 Cu In. If A 360 Cu In. Engine Of The Same Kind Develops 210 Hp? This problem ha

exis [7]

Answer:

about 130 hp

Step-by-step explanation:

The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:

(220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp
