Which 2 teams scored a total of 100 points, red has 29 points, yellow has 38 points, Green has 41 points, blue has 76 points ora

Bess [88]

Answer:

Blue and Black

Step-by-step explanation:

hi! i think you're asking which of the 2 teams' points added together equal 100. if so, it would be blue and black because 76 + 24 = 100.

broken down: 70 + 20 = 90, 6 + 4 = 10, 90 + 10 = 100 :)

hope i understood this right!

Examine the system of equations.

11Alexandr11 [23.1K]

<h3><u>Explanation</u></h3>

Given the system of equations.

$y = - \frac{1}{4} x - 2 \\ x = 4$

Substitute x = 4 in the first equation.

$y = - \frac{1}{4} (4) - 2 \\ y = - 1 - 2 \\ y = - 3$

We have both x and y values. Therefore, we can answer in coordinate point form.

<h3><u>Answer</u></h3>

<u> $\large \boxed{(4, - 3)}$ </u>

How many 10-digit ternary strings are there that contain exactly two 0s, three 1s, and five 2s?

Svet_ta [14]

There are $\dbinom{10}2$ ways of picking 2 of the 10 available positions for a 0. 8 positions remain.

There are $\dbinom83$ ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's $\dbinom55=1$ way of doing that.

So we have

$\dbinom{10}2\dbinom83\dbinom55=\dfrac{10!}{2!(10-2)!}\dfrac{8!}{3!(8-3)!}\dfrac{5!}{5!(5-5)!}=2520$

The last expression has a more compact form in terms of the so-called multinomial coefficient,

$\dbinom{10}{2,3,5}=\dfrac{10!}{2!3!5!}=2520$

-1 3/5 divided by -2/3 written as mixed number

blondinia [14]

First, you must change all of this into improper fractions, like shown below.
$- \frac{8}{5}\div - \frac{2}{3} =$
Now you must change the sign.
$- \frac{8}{5}* - \frac{2}{3} =$
Then we must reciprocalize 2/3.
$- \frac{8}{5}* - \frac{3}{2} =$
Now we multiply, to get 2 4/10.
