An ABC News poll asked adults whether they felt genetically modified food was safe to eat. Thirty-five percent felt it was safe, 52% felt it was not safe, and 13% had no opinion.

Rod is a drummer who purchases his drumsticks online. When practicing with the newest pair, he notices they feel heavier than usual. When he weighs one of the sticks, he finds that it is 2.66 oz. The manufacturer's website states that the average weight of each stick is 2.25 oz with a standard deviation of 0.17 oz. Assume that the weight of the drumsticks is normally distributed.What is the probability of the stick's weight being 2.66 oz or greater

Answers

Answer: 0.0080

Step-by-step explanation:

Given : The manufacturer's website states that the average weight of each stick is $\mu=2.25$ oz with a standard deviation of $\sigma=0.17$ oz.

We assume the weight of the drumsticks is normally distributed.

Using formula $z=(x-\mu)/(\sigma)$ , the z-value corresponds x=2.66 will be :-

$z=(2.66-2.25)/(0.17)\approx2.41$

By using the standard normal distribution table for z, we get

P-value = $P(z\geq2.41)=1-P(z<2.41)$

$\n\n=1-0.9920237=0.0079763\approx0.0080$

Hence, the probability of the stick's weight being 2.66 oz or greater=0.0080

Which of the following is the quotient of the rational expressions shown below? 5x/2x+3 / x+1/3x

Answers

find the attached picture.

The given fraction involves two Rational Expressions, one in numerator and one in denominator.

The rational expression in the denominator can be multiplied to the numerator after taking its reciprocal, this will help to simplify the expression as shown below:

$( (5x)/(2x+3) )/( (x+1)/(3x) ) \n \n = (5x)/(2x+3) * (3x)/(x+1) \n \n = (15 x^(2) )/((2x+3)(x+1))$

There are no common factors in the numerator and the denominator so the expression cannot be simplified any further.
