Answer:

Solution:

The greatest of Winnie's even numbers is $2\times 30 = 60,$ so her sum is

\[2+4+6+\cdots + 58 + 60.\]For Grogg's sum, there are five odd numbers between $0$ and $-10$, five between $-10$ and $-20$, and so on, so Grogg's sum is

\[(-1)+(-3)+(-5)+\cdots+(-57)+(-59).\]

We could compute these sums separately and find their difference, but instead, we'll look for a clever way to regroup to compute the difference

\[(2+4+6+\cdots +58+60)-((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Noting that Winnie's list steps up by 2 at each term while Grogg's steps down by 2 at each step, we write Winnie's list backwards, so that each list goes down by 2 at each step:

\[(60+58+56+\cdots + 4+2) - ((-1)+(-3)+(-5)+\cdots +(-57)+(-59)).\]Now, we see that the difference between a term in Winnie's backwards list and the corresponding term in Grogg's list is always the same:

\begin{align*}

60-(-1) &= 61,\\

58-(-3) &= 61,\\

56-(-5) &=61,\\

\vdots&\\

2-(-59) &= 61.

\end{align*}There are 30 such differences, so Winnie's sum is $30\times 61 = \boxed{1{,}830}$ greater than Grogg's sum.

Answer:

[tex]y - 4x = 1[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (1,5)[/tex]

[tex](x_2,y_2) = (3,13)[/tex]

Required

The equation of the line

Back up:

First, calculate the slope(m)

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{13-5}{3-1}[/tex]

[tex]m = \frac{8}{2}[/tex]

[tex]m = 4[/tex]

Calculate the area using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y- 5 = 4(x - 1)[/tex]

[tex]y- 5 = 4x - 4[/tex]

Collect Like Terms

[tex]y - 4x = 5 - 4[/tex]

[tex]y - 4x = 1[/tex]

Answer:

12.56 inches

Step-by-step explanation:

Circumference: C = 2*pi*r

I will be using 3.14 in place of pi

Divide the diameters by 2, so 3 for Zoey and 5 for Sam

Multiply (2*3.14*3) and (2*3.14*5)

For Zoey you get 18.84 and for Sam you get 31.4

31.4-18.84= 12.56 in difference

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

32=4(n−5);−s+11=17

Rewrite equations:

32=4n−20;−s+11=17

Step: Solve 32=4n−20 for n:

32=4n−20

32+−4n=4n−20+−4n(Add -4n to both sides)

−4n+32=−20

−4n+32+−32=−20+−32(Add -32 to both sides)

−4n=−52

−4n/ −4 =/ −52/ −4

(Divide both sides by -4)

n=13

Step: Substitute 13 for n in  −s+11=17:

−s+11=17

−s+11=17

−s+11+−11=17+−11(Add -11 to both sides)

−s=6

−s/ −1 = 6/ −1

(Divide both sides by -1)

s=−6

Answer:

n=13 and s=−6

Answer:

36 days

Step-by-step explanation:

Given

[tex]p = 0.15[/tex] -- probability of coming late to work

[tex]n = 240[/tex] -- number of days

Required

Determine the expected number of days of coming late (E(x))

This is calculated using:

[tex]E(x) = np[/tex]

[tex]E(x) = 240 * 0.15[/tex]

[tex]E(x) = 36[/tex]

The expected number of days is 36
