Answer:

$-\frac{4}{3}$

Step-by-step explanation:

$-3 \frac{3}{5}$ ÷ $2 \frac{7}{10}$

Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.

$- \frac{18}{5}$ ÷ $\frac{27}{10}$

Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.

$-\frac{18}{5} * \frac{10}{27}$

$= -\frac{180}{135}$

Simplify;

= $-\frac{4}{3}$

artcher [175]

Answer:

3.3 hours.

Step-by-step explanation:

We have been given that a scientist is testing a new antibiotic by applying the antibiotic to a colony of 10,000 bacteria. The number of bacteria decreases by 75% every two hours.

Since number of bacteria is decreasing exponentially, so we will use exponential decay function.

$y=a*b^x$ , where,

a= Initial value,

b = For decay b is in form (1-r), where r is rate in decimal form.

Let us convert our given rate in decimal form.

$75\%=\frac{75}{100}=0.75$

As number of bacteria is decreasing every 2 hours, so number of bacteria decreased in 1 hour will be x/2.

Upon substituting our given values in above formula we will get,

$y=10,000(1-0.75)^{\frac{x}{2}}$

To find the number of hours it will take to for the bacteria colony to decrease to 1000, we will substitute y = 1,000 in our equation.

$1,000=10,000(0.25)^{\frac{x}{2}}$

Let us divide both sides of our equation by 10,000.

$\frac{1,000}{10,000}=\frac{10,000(0.25)^{\frac{x}{2}}}{10,000}$

$0.1=(0.25)^{\frac{x}{2}}$

Let us take natural log of both sides of our equation.

$ln(0.1)=ln((0.25)^{\frac{x}{2}})$

$ln(0.1)=\frac{x}{2}*ln(0.25)$

$-2.302585=\frac{x}{2}*-1.386294$

$x=\frac{-2.302585}{-1.386294}*2$

$x=1.660964*2$

$x=3.3219\approx 3.3$

Therefore, it will take 3.3 hours for the bacteria colony to decrease to 1000.

Consider a political discussion group consisting of 4 Democrats, 9 republicans, and 4 independents. Suppose that two group membe

iragen [17]

All in all, we are selecting from a pool of 17 members (4+9+4 = 17). So seeing we have 4 democrats, the probability would be 4/17.

Normally we would simplify the fraction from there but 4/17 is already the simplified form. Therefore that is already the answer.
