I figured it out!! Yay!

You take 7.8 and divide it by 24 which will get you 0.325
In order to get it match one of the options, multiply it by 10 (which will add 1 to 105!) Leaving you 3.25*106

One senior from the high schools will be selected at random. What is the probability that the senior selected will not be from h

DochEvi [55]

Using the probability concept, it is found that there is a 0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.

<h3>What is a probability? </h3>

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that:

538 seniors responded with a choice other than college.

Of those students, 99 + 83 + 49 + 31 + 63 + 71 = 396 are not from high school b.

Hence:

$p = \frac{396}{538} = 0.7361$

0.7361 = 73.61% probability that the senior selected will not be from high school b given that the senior responded with a choice other than college.

1. -3x=21 2. 13x=6 3. -12x=-7 answer the equation for points and brainiest.

andre [41]

Answer:

1. x = -7

2. x = 6/13

3. x = 7/12

Step-by-step explanation:

1. x = 21 / -3

x = -7

2. 13x = 6

x = 6 / 13

x = 6/13

3. -12x = -7

x = -7 / -12

x = 7/12

Hope that helps!

Rounded to the nearest dime ,what is the greatest amount of money that rounds to $105.40?What is the least amount of money that

victus00 [196]

$100.00 rounded value
$105.00 rounded value
$110.00 rounded value

For example,
14,494 
To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: 
10, 000 = ten thousand 
4, 000 = thousands 
400 = hundreds 
90 = tens 
4 = ones 
Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.

Are the functions f(x) = (x^2-1)/(x-1) and g(x)= x+1 equal for all x?

Vinvika [58]

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\$

$\bf f(x)=\cfrac{x^2-1}{x-1}\implies f(x)=\cfrac{x^2-1^2}{x-1}\implies f(x)=\cfrac{(\underline{x-1})(x+1)}{\underline{x-1}}
\\\\\\
f(x)=x+1\qquad \qquad \qquad \qquad \qquad g(x)=x+1\\\\
-------------------------------\\\\
\textit{they're, kinda, except that, when x = 1}
\\\\\\
g(x)=(1)+1\implies g(x)=2
\\\\\\
f(x)=\cfrac{(1)^2-1}{(1)-1}\implies f(x)=\cfrac{0}{0}\impliedby und efined$
