Enter the value of p so the expression 5/6 - 1/3n is equivalent to p(5-2n).

Answers

Let's solve for p when the two expressions are equal.

p(5-2n)=\frac{5}6 - \frac{1}3n \n\n p=\frac{\frac{5}6-\frac{1}3n}{5-2n}*\frac{6}6= (5-2n)/(6(5-2n)) = \boxed{\frac{1}6}

I ran into this same problem here on Brainly a couple of
weeks ago.  Only the drawing was posted, without asking
a question.  This one has some words with it, but it's not much
better than the other one was.

When you read it carefully, you can see blanks where there's
supposed to be something more written:

WHAT is equal to 3x + 9 ?

WHAT is equal to 8x + 11 ?

WHAT is equal to 5x - 8 ?

Find the  measures of WHAT, WHAT, and WHAT ?

You can't do a thing with this as it is.  It doesn't tell you
anything that you can work with.

If A is to the left of B on a number line, which of the following must be true?A.) A<B
B.) A=B
C.) A>B

Answers

Answer:

A.A<B

Step-by-step explanation:

We have been given that A is one the left of B on a number line. We are asked to choose the correct option from our given choices about the given condition.

We know that the value of numbers on number line increases from left to right.

Since A is on the left of B on number line, therefore, the value of a must be less than B and option A is the correct choice.

A box plot was made to represent the number of matches won by 14 participants in a tennis tournament. The box plot had the box shifted to the right so that the left tail was much longer than the right tail. Based on the box plot, which conclusion is correct? (A)The mean and median of matches won are equal.
(B)The mean of matches won is more than the median of matches won.
(C)Most of the participants won many matches, but there were some participants who won very few matches compared to the others.
(D)Most of the participants won very few matches, but there were some participants who won many matches compared to the others.

Answers

Answer:

(C)- Most of the participants won many matches, but there were some participants who won very few matches compared to the others.

Step-by-step explanation:

The Box plot isshifted to the right this means it is right-skewed data thus left tail is much longer than right tail. Hence, Option (C) is correct.

Option (A) means than neither right tail is longer nor left, the box will remain in middle only. So it is incorrect.

Option (B) is incorrect because Box Plot doesn't give us idea about mean.

Option (D) is also not correct because if this happened then box will shifted to the left
The box plot had the box shifted to the right so that the left tail was much longer than the right tail. Based on the box plot, the conclusion that is correct is Most of the participants won very few matches, but there were some participants who won many matches compared to the others. The answer is letter D
