Answer:

<h2>A good estimate would be</h2>

\frac{9}{20} and \frac{11}{20}.

Step-by-step explanation:

To solve this problem, you can find the probability of each case, red chips and yellow chips, which are gonna be simple probabilities, that is, the quotient between the number of events and the number of possible outcomes.

We know that the student reaches nine red chips out of 20, the probability is

P_{red}=\frac{9}{20}

Also, the students reaches eleven yellow chips out of 20, so

P_{yellow} =\frac{11}{20}

Thefeore, a good estimate would be \frac{9}{20} and \frac{11}{20}.

Pls only answer if yk it ill give correct one BRAINLIEST!!
Dmitry [639]

Answer:

X=10, x=4

Step-by-step explanation:

first, divide 14 by 2, and square it; giving you

x^2-14x+(7)^2=-40

Because 7^2 is 49, you have to add 49 to the other side; giving you

x^2-14x+(7)^2=9

Then factor the left side; giving you (x-7)^2=9

Take the square root of both sides, giving you

(x-7)^2= plus or minus 3

Then solve to get two solutions, 10 and 4

Find d<br><br> a * a * a = 216<br> a * b * c = 96<br> b * c = 52<br> a + b + c = d
Slav-nsk [51]

a\cdot a\cdot a=216\\\\a^3=216\to a=\sqrt[3]{216}\\\\\boxed{a=6}\\\\\text{Substitute}\ b\cdot c=52\ \text{to the second expression}\ a\cdot b\cdot c=96:\\\\abc96\ \wedge\ bc=52\to a(52)=96\qquad\text{divide both sides by 52}\\\\a=\dfrac{96}{52}\to a=\dfrac{24}{13}\neq6

a = 6 and a = 24/13  FALSE!!!
