Can someone help me with this question me and my friends are fighting over it?

1 answer:

4 0

Okay so I am not 100% sure but I think it is C. 1/12;

Because if you rearrange all the letters so that W is is the beginning you get 6 different combinations.

Then I multiplied those 6 combinations by 4 because there are 4 letters.

Once I multiplied I got 2/24 because there are 24 possibilities in total, and we are looking for the probability of getting those 2 combinations.

I simplified 2/24 to its lowest form and I got 2/24 = 1/12.

So the correct answer is C.1/12, hope this helps!

The population of a town has grown at an annual rate of 2.7%. How long does it take for it’s population of 18,450 people to doub

It would take 26 years.

The equation will be in the form y = a(1+r)ˣ, where a is the initial population, r is the growth rate as a decimal number, and x is the amount of time. Using our information we have

y = 18450(1+0.027)ˣ = 18450(1.027)ˣ

We want the population to be doubled; 18450*2 = 36900:
36900 = 18450(1.027)ˣ

Divide both sides by 18450:
36900/18450 = 18450(1.027)ˣ/18450
2 = 1.027ˣ

Using logarithms, we have
$\log_{1.027}2=x
\\
\\x=26.017$

Answer:

x=-3

Step-by-step explanation:

You need to delete the root by ^2. First you need to leave it alone

$\sqrt{x+7}-x=5\\\sqrt{x+7}=5-x\\(\sqrt{x+7} )^{2}=(5-x)^{2} \\x+7=25+10x+x^2\\x-10x=25+x^2-7\\-9x=18+x^2\\-x^2-9x-18=0\\-1(x^2+9x+18)=0\\x^2+9x+18=\frac{0}{-1}\\x^2+9x+18=0\\(x+6)(x+3)=0\\x+6=0 ===> x=-6\\x+3=0 ===> x=-3\\Checking\\\sqrt{-6+7}-(-6)=5===>\sqrt{1}+6=7\neq5 \\\\\sqrt{-3+7}-(-3)=5===>\sqrt{4}+3=5=5\\\\So \\x=-3$

There is a line that includes the point (3, 8) and has a slope of 6 . What is its equation in slope-intercept form ?

goldenfox [79]

Answer:

y=6x-10

Step-by-step explanation:

Use Point-Slope form to solve this problem

Point Slope Form: y-y1=m(x-x1)

M is your slope, in this case, m will be 6

Plug in the values of your coordinates (3,8), ambigously, 3 will be the value of x1 and 8 will be the value of y1.

New equation: y-8=6(x-3), start solving from here

y-8=6x-18

Use inverse operations to get y alone, opposite of subtraction is additiin so add 8 to both sides of the equation

y=6x-10
