A motorcycle costs 12000. The value of the motorcycle deceases 6% each year. What is the rate each month

quester [9]

There are 12 months in a year and each year it decreases 6% so therefore each month it decreases .5%.

If you were asking the the amount it depreciates each month then you take .5% or .005 of 12000 which is 60 dollars a month.

The measure of one of the small angles of a right triangle is 15 less than twice the measure of the other small angle. Find the

gulaghasi [49]

Answer:

35° and 55°

Step-by-step explanation:

The sum of the angles of a right rectagle is 180°, with a right angle of 90°.

The tell us that A = 2B-15, so:

180° = 90° + A + B

180° = 90° + 2B - 15 + B

180° - 90° + 15 = 2B + B

105° = 3B

B = 105°/3 = 35°

Now, let's find A:

A = 180° - 90° - 35° = 55°

In an effort to determine the most effective way to teach safety principles to a group of employees, four different methods were

musickatia [10]

Answer:

critical value = 5.29

Step-by-step explanation:

Given that they are divided into 4 groups and a sample of 5 test was selected

N = 5 * 4 = 20

k = 4

∝ = 0.01

Df for numerator ( SS group )= k - 1 = 3

Df for denominator ( SSE group ) = N - k = 20 - 4 = 16

DF ( degree of freedom )

Next we will use the F table to determine the critical value

Critical value = $F_{16,3,0.01}$ = 5.29
