Answer: Option 'B' is correct.

Step-by-step explanation:

Since we know that

Translation means that every point of the object that must be moved in the same direction for the same distance.

So, Chairs around a round table is the example of rotation.

Baby bird and mother bird is the situation in which mother bird is the largest version of her baby bird.

So, it is an example of enlargement.

Left and right hand is the reflection of each other.

But seats on a school bus is the example of translation as the every seat is moved in the same direction for the same distance.

Hence, Option 'B' is correct.

Answer: 0.71221

Step-by-step explanation:

We know that for binomial distribution :-

$\mu=np\ \ ;\ \sigma=\sqrt{np(1-p)}$ , where p is the proportion of success in each trial and n is the sample size.

Given : p=0.80 ; n=20

Then, $\mu=20(0.8)=16\ \ ;\ \sigma=\sqrt{20(0.8)(0.2)}=1.79$

Let X be the binomial variable.

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x=9

$z=\dfrac{9-16}{1.79}=-3.91$

For x=17

$z=\dfrac{17-16}{1.79}=0.56$

Then, the probability that more than 9 but less than 17 of the hotels in the sample is given by :-

$P(9$

Hence, the probability that more than 9 but less than 17 of the hotels in the sample = 0.71221

2y + 12 = -3x

Step-by-step explanation:

Divide y y by 1 1 . Divide 12 12 by 2 2 . Use the slope-intercept form to find the slope and y-intercept. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

Answer:

Mean = 2.95

Median = 3

Step-by-step explanation:

The mean of the number of visits of 40 adults to the gym is

$\dfrac{0\cdot 4+1\cdot 3+2\cdot 12+3\cdot 5+4\cdot 8+5\cdot 5+6\cdot 2+7\cdot 1}{40}=\\ \\=\dfrac{3+24+15+32+25+12+7}{40}=\dfrac{118}{40}=2.95$

The median of the data is the average number between 20th and 21th terms (because 40 is even number, so the middle term is the average between two middle terms).

20th term = 3 visits

21th term = 3 visits

Hence, median is 3 visits
