sock, not replace it, and then draw another white sock without looking?
0.10=10%
0.098=9.8%
0.078=7.8%
0.08.=8.3%

I am not sure how sigma notation works, can somebody explain how to solve this? It isn't the second choice.

Masja [62]

Answer:

first answer is correct

Step-by-step explanation:

Hello, we want to write 2 + 4 + 6 + ... + 20

for n = 1, 2n = 2*1 =2

for n = 2, 2n = 2*2=4

for n = 3, 2n=2*3=6

etc

so

$\displaystyle \sum_{n=1}^{10} {2n} = 2*1 + 2*2 +2*3+2*4+...+2*10=2+4+6+8+...+20$

thanks

Rewrite the following linear equation to slope form :y+2=7(2x-4)

garik1379 [7]

Answer:

y = 14x -30

Step-by-step explanation:

The slope intercept form is:

y = mx + b,

Slope intercept form is useful for finding the slope and y intercept of a line, hence why it is called "slope intercept" because it is easy to see the slope and the y intercept of a line in this form. Since the slope denoted by m, and y intercept denoted by b are clearly given.

y + 2 = 7(2x - 4)

Distribute 7 across the parentheses by multiplying x and 2x and 4 by 7.

y+2 = 14x - 28

subtract 2 from both sides. This cancels the 2 on the left and moves it to the right, while keeping the equation balanced.

y+2 -2 = 14x - 28 -2

y = 14x - 30

y = 14x -30

As you can see our y = 14x -30 now looks like the point slope equation we had above. m = 14, and b = -30. This means the line goes up 14 for every single unit you move to the right, and intersects the y axis at (0, -30).

To get on the top players list , don needs to have a minimum average score of 225 after playing four games. His scores on his fi

Black_prince [1.1K]

Average must be 225 or more
4 games so
$\frac{score1+score2+score3+score4}{4} \geq 225$
score1=192
score2=214
score3=250
score4=?
so
$\frac{192+214+250+?}{4} \geq 225$
$\frac{656+?}{4} \geq 225$
times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides
?≥244

min score is 244
