Answer:

I mean I can give you some of my advice on 7 but I'm not too great on the others, but I hope this will help:

Step-by-step explanation:

Okay so on 7 you first need to figure out the amount of people in each grade and then you need to look at the premade answers and try to split it up AND on the total part you need to put how many people all together. If I'm not mistaken, I'm pretty sure there are more right-handed people, then left-handed people on 7th graders.

2 If a hockey team loses 33% of the games they play, what is the probability that this team will win exactly 10 games out of the

Gekata [30.6K]

They lose 33% of games i.e 0.33
They win 67% of games i e 0.67

So

P(A)=0.33
P(A')=0.67

Now

They win from 15games=10
They lose=5

The required probability

$\\ \rm\rightarrowtail P(A')^{10}\times P(A)^5\times ^{15}C_{10}$

$\\ \rm\rightarrowtail (0.33)^{5}\times (0.67)^{10}\times \dfrac{15!}{5!10!}$

$\\ \rm\rightarrow 0.0039(0.0182)\times\dfrac{15(14)(13)(12)(11)10!}{5!10!}$

$\\ \rm\rightarrowtail 0.00007098\times \dfrac{360360}{120}$

$\\ \rm\rightarrowtail 0.00007098(3003)$

$\\ \rm\rightarrowtail 0.213$

So probability

0.213(100)=21.3%

Answer:

It removes the repeating part of the decimal from the equation.

Step-by-step explanation:

Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q

1) --------------

x = 0.555555

2) --------------

10x = 5.555555

3) --------------

10 x - x = 5.555555 - 0.555555
9x = 5
x = 5/9

So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Correct option is the first one.

Rachel hikes at a steady rate from a ranger station to a campground that is 20 mi away. After 2 h, she is 13 mi from the campgro

umka2103 [35]

From 2 hours to 4 hours she traveled 7 miles.

7 miles / 2 hours = 3.5 miles per hour.

The slope is 3.5 , which is 3.5 miles per hour, which is how fast she is walking.
