Pedro must make $330 on the 6th day to have a mean average of $200.

Step-by-step explanation:

Formula for Mean Average

Mean Average = $\frac{Sum of data}{Total number of data}$

DATA:

1st day = $120

2nd day = $110

3rd day = $200

4th day = $300

5th day = $140

6th day = x

Solution:

Mean Average = $\frac{Sum of data}{Total number of data}$

200 = $\frac{120+110+200+300+140+x}{6}$

200*6 = 870+x

1200 - 870 = x

x = 330

Pedro must make $330 on the 6th day to have a mean average of $200.

Which phrase is best represented by the algebraic expression x/4 -2

Ber [7]

Answer:

D) 2 less than the quotient of x divided by 4

Step-by-step explanation:

Since it's x/4 there has to be a quotient or division involved in the sentence, which eliminates A and B. Since there's a -2, C is eliminated since it doesn't include 2.

Triangle EFG in which segment EF measures 3 units and segment FG measures 5 units

Softa [21]

Answer:

Yes

Step-by-step explanation:

It can be 6 units. The rule relating to the sides of the triangle is that you should be able to add two sides and get a length that is longer than the third side. You usually add the lower two numbers because it basically says that it will work for all sides but, if you're still in doubt you just have to compare the numbers.

For Example

3+5 is greater than 6

5+6 is greater than 3

6+3 is greater than 5.

All of these makes sense so 6 can be a possible answer.
