The relationship between the mean and median of the collected data is that the mean will be smaller than the median.

Since the SAT Math scores for these students will be mostly high scores, the distribution will be skewed to the left. Thus, the few low scores (outliers) will make the mean smaller than the median.

Outliers that do not change the mean have an impact just on the mean. As a result, the mean is frequently lower than that of the median when the distribution of data is skewed to the left. The mean is frequently higher than the median when the distribution is tilted toward the right. We anticipate that the mean and median in symmetrical distribution will be about identical in value. This is a crucial link between the connection here between mean and median as well as the distribution's form. Nevertheless, it isn't applicable to all sets of data. Collections of data sets are where exceptions happen much more frequently.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options.
Elza [17]

Question is Incomplete; Complete question is given below.

Which expressions are equivalent to 8 (negative 10 x + 3.5 y minus 7)? Select two options. Negative 80 x + 24.5 y minus 56 Negative 80 x + 28 y minus 56 80 x + 28 y + 56 4 (negative 20 x + 7 y minus 14) Negative 4 (negative 20 x + 7 y minus 14)

Answer:

Negative 80 x + 28 y minus 56

4 (negative 20 x + 7 y minus 14)

Step-by-step explanation:

Given:

8(-10x+3.5y-7)

We need to find the equivalent expression for given expression.

Solution:

8(-10x+3.5y-7)

First we will apply distributive property for given expression.

a(x+y) =ax+ay

So we get;

8\times-10x+8\times3.5y-8\times7\\\\-80x+28y-56

Hence first expression equivalent to given expression is -80x+28y-56.

Now again evaluating the expression we get;

We will take 4 as common factor from the expression we get;

-4\times20x+4\times7y-4\times14\\\\4(-20x+7y-14)

Hence second expression equivalent to given expression is 4(-20x+7y-14).

Choose your favourite cars and describe about it. Speak for about 3 minutes.
Soloha48 [4]

Answer:

LAMBORGHINI

Step-by-step explanation:

The fact that Ferruccio Lamborghini first owned a Ferrari during his younger stage and it wasn't up to par for him still amazes me. He also had the guts to "repair" what was wrong with the Ferrari he had in his opinion and so Ferrari did not like that someone who at the time had a work related in the farms was telling him the imperfections that there was with a Ferrari since they were top tier luxury cars.

This is where the whole legacy that Ferruccio Lamborghini would leave behind started. He decided to switch fixing Ferraris as a hobby to making it a passion. Ever since Ferruccio's goal was to build a car that was equal or better than any Ferrari model at that time. People believed this was impossible!

In modern day standards both brands have continued to grow each making unique cars for different styles of people but If I had to chose one, It would be Lamborghini (Gallardo Super Trofeo) :)

Given the following: P(A) =0.3 P(B) = 0.2 P(A OR B) = 0.5 P(A AND B) = 0 Which of the following is true?a. A and B are disjoint.
erastova [34]

Answer:

a. A and B are disjoint

Step-by-step explanation:

We know that P(A and B)=0, It means that event A and event B have nothing in common and it means that event A and event B are disjoints events.

The event A and event B are independent if

P( A and B)= P(A)*P(B)

P(A)*P(B)=0.3*0.2=0.06

So, P(A and B)≠P(A)*P(B)

Hence events A and B are not independent.

Option a is A and B are disjoints which is correct

Option b is A and B are neither disjoints nor independent which is partially false as A and B are disjoints event.

Option c states that A and B are independent which is clearly false.

Option d states that A and B are disjoints and independent which is partially false as A and B are not independent.

Hence the correct option is option A.
