Answer:

2. A 4-column table with 3 rows. The columns are labeled First Spinner and the rows are labeled Second spinner. Column 1 has entries 2A, 2B, 2C. Column 2 has entries 4A, 4B, 4C. Column 3 has entries 6A, 6B, 6C. Column 4 has entries 8A, 8B, 8C.

Step-by-step explanation:

Franz and his friends are using the spinners below to play a game.

A spinner has 4 equal sections labeled 2, 4, 6, 8. Another spinner has 3 equal sections labeled A, B, C.

If one turn consists of spinning each spinner once, the table which will show all the possible outcomes for one turn will be,

A major airline is concerned that the waiting time for customers at its ticket counter may be exceeding its target average of 19

sertanlavr [38]

Answer:

a) Statement is true

b) Statement incorrect. Company goal is to attend customer at 190 second at the most. So test should be one tail test (right)

c) We have to reject H₀, and differences between sample mean and the hypothesized population mean should not be attributed only to sampling error

Step-by-step explanation:

a) as the significance level is = 0,02 that means α = 0,02 (the chance of error type I ) and the β (chance of type error II is

1 - 0.02 = 0,98

b) The company establishe in 190 seconds time for customer at its ticket counter (if this time is smaller is excellent ) company is concerned about bigger time because that could be an issue for customers. Therefore the test should be a one test-tail to the right

c) test statistic

Hypothesis test should be:

null hypothesis H₀ = 190

alternative hypothesis H₀ > 190

t(s) = ( μ - μ₀ ) / s/√n ⇒ t(s) = ( 202 - 190 )/(28/√100 )

t(s) = 12*10/28

t(s) = 4.286

That value is far away of any of the values found for 99 degree of fredom and between α ( 0,025 and 0,01 ). We have to reject H₀, and differences between sample mean and the hypothesized population mean should not be attributed only to sampling error

If we look table t-student we will find that for 99 degree of freedom and α = 0.02.

Solve the system using elimination: -3x - 3y = 12 -9x + 3y = -24 The answer is not (-1,-3)

FinnZ [79.3K]

Answer:

{x = 1, y = -5

Step-by-step explanation:

Solve the following system:

{-3 x - 3 y = 12 | (equation 1)

{3 y - 9 x = -24 | (equation 2)

Swap equation 1 with equation 2:

{-(9 x) + 3 y = -24 | (equation 1)

{-(3 x) - 3 y = 12 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{-(9 x) + 3 y = -24 | (equation 1)

0 x - 4 y = 20 | (equation 2)

Divide equation 1 by 3:

{-(3 x) + y = -8 | (equation 1)

{0 x - 4 y = 20 | (equation 2)

Divide equation 2 by 4:

{-(3 x) + y = -8 | (equation 1)

{0 x - y = 5 | (equation 2)

Multiply equation 2 by -1:

{-(3 x) + y = -8 | (equation 1)

{0 x+y = -5 | (equation 2)

Subtract equation 2 from equation 1:

{-(3 x)+0 y = -3 | (equation 1)

{0 x+y = -5 | (equation 2)

Divide equation 1 by -3:

{x+0 y = 1 | (equation 1)

{0 x+y = -5 | (equation 2)

Collect results:

Answer: {x = 1 , y = -5

The answer to all of these problems

-BARSIC- [3]

1) area of a cicular pool
area of a circle=πr^2 d=2.5 then r=2.5/2
A=3.14 *(2.5/2)^2
A=4.906m^2 A=4.9m^2

2) arae of a coin
(if i read it right d=15mm?)
A=πr^2 d=15 then r=15/2
A=3.14*(15/2)^2 =176.6mm^2

Rest all are same problems u try to solve it
