ExtremeBDS [4]3 years ago
4 0

Answer:

m=2

Step-by-step explanation:

RS=2m+2

ST=3m+3

RT=15

m=2

RS=2(2)+2

RS=4+2

RS=6

ST=3(2)+3

ST=6+3

ST=9

Because S is in the middle of RT, if you add RS and ST together, you will get the length of RT.

6+9=15

- f(x) = 3x3 – 21ײ – 54x<br>Zero<br>Multiplicity<br>Effect​
xenn [34]

Answer:

x = 9 or x = 0 or x = -2

Step-by-step explanation:

Solve for x:

3 x^3 - 21 x^2 - 54 x = 0

The left hand side factors into a product with four terms:

3 x (x - 9) (x + 2) = 0

Divide both sides by 3:

x (x - 9) (x + 2) = 0

Split into three equations:

x - 9 = 0 or x = 0 or x + 2 = 0

Add 9 to both sides:

x = 9 or x = 0 or x + 2 = 0

Subtract 2 from both sides:

Answer:  x = 9 or x = 0 or x = -2

zhuklara [117]

Answer:

a. 5% of the employees will experience lost-time accidents in both years

b. 24% of the employees will suffer at least one lost-time accident over the two-year period

Step-by-step explanation:

a. What percentage of the employees will experience lost-time accidents in both years?

20% last year, of those who suffered last year, 25% during this year. So

p = 0.2*0.25 = 0.05

5% of the employees will experience lost-time accidents in both years.

b. What percentage of the employees will suffer at least one lost-time accident over the two-year period?

5% during the two years.

10% during the current year. 25% of employees who had lost-time accidents last year will experience a lost-time accident during the current year.

So the 10% is composed of 5% during both years(25% of 20%) and 5% of the 80% who did not suffer during the first year.

First year yes, not on the second.

75% of 20%. So, total:

0.05 + 0.05*0.8 + 0.75*0.2 = 0.24

24% of the employees will suffer at least one lost-time accident over the two-year period
