Answer:

$\frac{3}{5}$

Step-by-step explanation:

<u>Operations With Fractions</u>

Evaluate the expression:

$\displaystyle \frac{\frac{3}{4}}{\frac{5}{4}}$

The division of fractions is can be done by multiplying the fraction on the numerator by the reciprocal of the fraction on the denominator:

$\displaystyle \frac{\frac{3}{4}}{\frac{5}{4}}=\frac{3}{4}\cdot\frac{4}{5}$

Simplifying:

$\displaystyle \frac{\frac{3}{4}}{\frac{5}{4}}=\frac{3}{5}$

Answer: $\frac{3}{5}$

Since, we don't have the actual graph, I cannot give you a final answer. However, I can explain how to find the answer.

If you are looking for the color that the fans like the least, just pick the bar that is the smallest. This will be the correct answer.

Answer:

a) The probability that at least 5 ties are too tight is P=0.0432.

b) The probability that at most 12 ties are too tight is P=1.

Step-by-step explanation:

In this problem, we could represent the proabilities of this events with the Binomial distirbution, with parameter p=0.1 and sample size n=20.

a) We can express the probability that at least 5 ties are too tight as:

$P(x\geq5)=1-\sum\limits^4_{k=0} {\frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}}\\\\P(x\geq5)=1-(0.1216+0.2702+0.2852+0.1901+0.0898)\\\\P(x\geq5)=1-0.9568=0.0432$

The probability that at least 5 ties are too tight is P=0.0432.

a) We can express the probability that at most 12 ties are too tight as:

$P(x\leq 12)=\sum\limits^{12}_{k=0} {\frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}}\\\\P(x\leq 12)=0.1216+0.2702+0.2852+0.1901+0.0898+0.0319+0.0089+0.0020+0.0004+0.0001+0.0000+0.0000+0.0000\\\\P(x\leq 12)=1$

The probability that at most 12 ties are too tight is P=1.

Evaluate log base 12 of y^2, given log base 12=16

Ostrovityanka [42]

Answer:

y = 12^8

Step-by-step explanation:

Log base 12, y^2 = 16

y2 = 12^16

y = sqrt ( 12^16) = (12^16)^1/2

y = 12^8
