IM GIVING BRAINLIEST AND 100 POINTS NO JOKE. PLEASE HELP

Sav [38]

Answer:

i hope this helps

Step-by-step explanation:

if you have 100 people in the room and you interviewed all of them, (for number 6). that means that 70% of these people ate breakfast

70% of the total amount of people you interviewed is 70. That means that 70 people you interviewed, eat breakfast.

Then it also says, "of those 70% of people, 25% eat cereal"

That means 25% of those 70 people eat cereal, or 1/4 of that population does.

0.25 * 70 = 17.5. (of course you cannot have part of a person, but this is an example)

and of the 17.5 people, 30% of them eats it with extra sugar.

so 30% of 17.5 people is 5.25.

that means that there are 5.25 people who eat cereal with extra sugar.

i hope this helps, it took a while for me to try to help with this

i noticed that you made a mistake. the amount of people that eat cereal is 25% of 70% of the people. that means you have to find 0.25 of 0.7 <--- (you multiply not divide)

(0.25x 0.7) = 0.175

Find domain of y=rad20-6x

Evgesh-ka [11]

Domain, on an "even root" context, means, an even root cannot have a negative radicand, since say for example $\bf \sqrt{-25}\ne -5\qquad why?\implies (-5)(-5)=25$

so... you end up with an "imaginary value"

so... for the case of 20-6x
"x", the domain, or INPUT
can afford to have any value, so long it doesn't make the radicand negative

to check for that, let us make the expression to 0, and see what is "x" then

$\bf 20-6x=0\implies 20=6x\implies \cfrac{20}{6}=x\implies \cfrac{10}{3}=x$

now, if "x" is 10/3, let's see $\bf \sqrt{20-6\left( \frac{10}{3} \right)}\implies \sqrt{20-20}\implies \sqrt{0}\implies 0$

now, 0 is not negative, so the radicand is golden

BUT, if "x" has a value higher than 10/3, the radicand turns negative
for example $\bf x=\frac{11}{3}
\\\\\\

\sqrt{20-6\left( \frac{11}{3} \right)}\implies \sqrt{20-22}\implies \sqrt{-2}$

so.. that's not a good value for "x"

thus, the domain, or values "x" can safely take on, are all real numbers from 10/3 onwards, or to infinity if you wish
