Write down the formula of median​

Answers

Answer:

[tex]D = 1[/tex] --- Determinant

[tex]M = \frac{N+1}{2}th[/tex] --- Median

Step-by-step explanation:

Given

[tex]5m^2 - m = 0[/tex]

Required

Calculate the determinant (D)

This is calculated using

[tex]D = b^2 - 4ac[/tex]

In [tex]5m^2 - m = 0[/tex]

[tex]a = 5[/tex], [tex]b = -1[/tex] and [tex]c = 0[/tex]

So, we have:

[tex]D = b^2 - 4ac[/tex]

[tex]D = (-1)^2 - 4 *5*0[/tex]

[tex]D = 1 - 0[/tex]

[tex]D = 1[/tex]

simply combining like teams 3a-2b-ab-(a-b+ab)-4ab+2b-a STEP explanation plss​

Answers

Answer:

-6 a b + b + a

Step-by-step explanation:

Simplify the following:

-(a - b + a b) - a b - 4 a b + 2 b - 2 b + 3 a - a

Hint: | Group like terms in 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a.

Grouping like terms, 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a = -(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b):

-(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in -a b - 4 a b.

a b (-1) + a b (-4) = -5 a b:

-(a b - b + a) + -5 a b + (3 a - a) + (2 b - 2 b)

Hint: | Combine like terms in 3 a - a.

3 a - a = 2 a:

-(a b - b + a) - 5 a b + 2 a + (2 b - 2 b)

Hint: | Look for the difference of two identical terms.

2 b - 2 b = 0:

-(a b - b + a) - 5 a b + 2 a

Hint: | Distribute -1 over a b - b + a.

-(a b - b + a) = -a b + b - a:

-a b + b - a - 5 a b + 2 a

Hint: | Group like terms in -a b - 5 a b + b + 2 a - a.

Grouping like terms, -a b - 5 a b + b + 2 a - a = (-a b - 5 a b) + b + (-a + 2 a):

(-a b - 5 a b) + b + (-a + 2 a)

Hint: | Combine like terms in -a b - 5 a b.

a b (-1) + a b (-5) = -6 a b:

-6 a b + b + (2 a - a)

Hint: | Combine like terms in 2 a - a.

2 a - a = a:

Answer: -6 a b + b + a

The local news is conducting a poll of the residents' opinions regarding a new traffic law that is being proposed. At the end of a news segment, viewers had the opportunity to dial in or use social media to choose whether they agree or disagree with the law. A large sample size was represented, and this poll was repeated again one week later with similar results. When working with this data, what best applies?

Answers

Options :

a. The surveys are biased because people chose to respond or not.

b. Because of the large sample size, the results are most accurate of all members of the community.

c. The same sampling methods were used for both polls, demonstrating reliability.

Answer:

a. The surveys are biased because people chose to respond or not

Step-by-step explanation:

When surveys incorporates a large number of people of a whole population, coupled with the fact that subjects of the survey or research are not compelled to make a choice or air their opinion. In the scenario above, opinion about the new policy is to be expressed by a large audience whereby there is a high tendency that some will no interest in the news nor its content. Leaving only those audience who are more interested and likely the most affected by the policy to respond. This way there will be no distinction between those who disagree and those who fail to respond. It would be more advisable to employ a sample audience who are interested and woykd give a verdict on the policy.

Ricky spent $44 total on a baseball mitt and a ball. If the mitt cost
$2 more than 5 times the cost of the ball, find the cost of each
item.

Answers

Answer:

The baseball mitt was $37 and the ball was $7

Step-by-step explanation:

Let m represent the cost of the mitt and let b represent the cost of the ball

Set up a system of equations:

m + b = 44

m = 5b + 2

Solve by substitution by plugging in 5b + 2 as m in the first equation:

5b + 2 + b = 44

Solve for b:

6b + 2 = 44

6b = 42

b = 7

Plug in 7 into the first equation and solve for m:

m + b = 44

m + 7 = 44

m = 37

So, the baseball mitt was $37 and the ball was $7

factor 1/8 out of 1/8x-49/8​

Answers

Answer:

1/8(x - 49)

Step-by-step explanation:

When we factor out something, we are basically finding common factors from multiple terms to take out. Example:

ab + ac; factored out: a(b + c)

If we want to factor out 1/8 from 1/8x - 49/8, we simply divide the two terms by 1/8.

[tex]\frac{1/8}{1/8x}[/tex] The 1/8 cancel out giving us x so:

1/8(x - __)

The next term,

[tex]\frac{49/8}{1/8}[/tex]

When two fractions divide, you flip the bottom one and multiply them both,

[tex]\frac{49}{8} *\frac{8}{1}[/tex]

giving us 49.

The answer is: 1/8(x - 49)
