David played a video game 5 times. The list shows his scores.

1 answer:

6 0

You would add up all of the numbers and then divide them by 5 since you have a total of 5 different sets of numbers (To get the mean). Then you have to find the median by putting all of the numbers in numerical order and get the number in the middle. Finally you subtract the median from the mean and you end up getting “B” as your answer.

Square root of50 is it rational true or false

morpeh [17]

Rational numbers end
irrational numbers do not
pi is an irrational number
√2 is an irrational number
so
√50=√2 times √25=√2 times 5
irrational times rational =irrational
√2=irrational

answer is false, it is rrational

Factor the polynomial F(x) =x^3-x^2-4x+4 completely.

Norma-Jean [14]

Answer:

Step-by-step explanation:

PART 1:

Possible roots by noticing the coefficient of first term:

x = 1, -1

PART 2:

1 | 1 -1 -4 4

1 0 -4

1 0 -4 0

The remainder is zero, hence one factor is (x-1)

PART 3:

$x^3-x^2-4x+4=(x^2-4)(x-1)\\\\x^3-x^2-4x+4=(x+2)(x-2)(x-1)$

PART 4:

$f(x)=(x+2)(x-2)(x-1)\\\\=(x^2-4)(x-1)\\\\=x^3-4x-x^2+4\\\\=x^3-x^2-4x+4$

Rich deposited money into a bank account that earned 2.5% simple interest each year. After 2 years, he had earned $14.65 in inte

photoshop1234 [79]

we know that

The simple interest formula is equal to

$I=Prt$

where

P is the Principal amount of money to be invested

I is the amount of money in interest

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=2\ years\\ I=\$14.65\\r=0.025$

substitute in the formula above and solve for P

$14.65=P(0.025)(2)$

$P=14.65/[(0.025)(2)]$

$P=\$293$

therefore

the answer is

$\$293$

Which is a good comparison of the estimated sum and the actual sum of 7 7/8 + 2 2/11?

Ipatiy [6.2K]

7 7/8 can be estimated to 8

2 2/11 can be estimated to 2

8 + 2 = 10

7 7/8 = 56+7/8 = 63/8

2 2/11 = 22+2/11 = 24/11

63/8 + 24/11 = 693+192/88 = 10.06

So do you see how similar 10 and 10.06 are to each other? :)
