Answer:

1 1/12

Explanation: you're gonna subtract (2-1) and (3/4-2/3) but first write the numerators as the least common denominator which is 12. so you do 9-8/12 = 1 1/12. If it needs to be an improper fraction then 13/12.

A company studied the number of lost-time accidents occurring at its Brownsville, Texas, plant. Historical records show that 6%

Georgia [21]

Answer:

$\% E = 0.9 \%$

$\%E_1 = 10.1 \%$

Step-by-step explanation:

From the question we are told that

The probability that an employees suffered lost-time accidents last year is $P(e) = 0.06$

The probability that an employees suffered lost-time accident during the current year is

$P(c) = 0.05$

The probability that an employee will suffer lost time during the current year given that the employee suffered lost time last year is

$P(c | e) = 0.15$

Generally the probability that an employee will experience lost time in both year is mathematically represented as

$P(c \ n \ e) = P(e) * P(c \ |\ e)$

=> $P(c \ n \ e) = 0.06* 0.15$

=> $P(c \ n \ e) = 0.009$

Generally the percentage of employees that will experience lost time in both year is mathematically represented as

$\% E = P(e \ n \ c ) * 100$

=> $\% E = 0.009 * 100$

=> $\% E = 0.9 \%$

Generally the probability that an employee will experience at least one lost time accident over the two-year period is mathematically represented as

$P(e \ u \ c) = P(e) + P(c) - P(e \ n \ c)$

=> $P(e \ u \ c) = 0.06 + 0.05 - 0.009$

=> $P(e \ u \ c) = 0.101$

Generally the percentage of the employees who will suffer at least one lost-time accident over the two-year period is mathematically represented as

$\%E_1 = P(e \ u \ c) * 100$

=> $\%E_1 = 0.101* 100$

=> $\%E_1 = 10.1 \%$

If I deposit $100,000 in a retirement account that gives 8 % paid annually, what will be balance after 25 years?

Zinaida [17]

Answer:

$300,000

Step-by-step explanation:

To find 8% of 100,000 all you need to do is multiply 100,000 by .08.

100,000 (.08) = 8,000

The 8,000 accounts for one year, so now you have to multiply 8,000 by 25.

8,000 (25) = 200,000

Now add the initial amount to the additional 200,00 that will be paid to the retirement account.

100,000 + 200,000 = 300,000

The answer is $300,000.

Suppose that the functions q and r are defined as follows.

satela [25.4K]

Answer:

(r o g)(2) = 4

(q o r)(2) = 14

Step-by-step explanation:

Given

$g(x) = x^2 + 5$

$r(x) = \sqrt{x + 7}$

Solving (a): (r o q)(2)

In function:

(r o g)(x) = r(g(x))

So, first we calculate g(2)

$g(x) = x^2 + 5$

$g(2) = 2^2 + 5$

$g(2) = 4 + 5$

$g(2) = 9$

Next, we calculate r(g(2))

Substitute 9 for g(2)in r(g(2))

r(q(2)) = r(9)

This gives:

$r(x) = \sqrt{x + 7}$

$r(9) = \sqrt{9 +7{$

$r(9) = \sqrt{16}$ {

$r(9) = 4$

Hence:

(r o g)(2) = 4

Solving (b): (q o r)(2)

So, first we calculate r(2)

$r(x) = \sqrt{x + 7}$

$r(2) = \sqrt{2 + 7}$

$r(2) = \sqrt{9}$

$r(2) = 3$

Next, we calculate g(r(2))

Substitute 3 for r(2)in g(r(2))

g(r(2)) = g(3)

$g(x) = x^2 + 5$

$g(3) = 3^2 + 5$

$g(3) = 9 + 5$

$g(3) = 14$

Hence:

(q o r)(2) = 14
