Answer:  The P-Value is .039337. The result is not significant at p < .01.

Step-by-step explanation:

In the following Chi square table attached, the value is of df=8 and chi square statistic value of 16.22 is found to be between (15.507, X²₀.₀₅) and    ( 17.353, X²₀.₀₂₅).

Using the table for critical value calculation:-

Df=8 Critical value for 1%= 1.646, and we calculated our value of 17.353.

We can reject is on the basis of X²calculated > X²Critical.

The outcome doesn't falls to be in 1% of the distribution.

or

We can reject it on basis that the outcome between X²₀.₀₅ and X²₀.₀₂₅ whereas the required level of upper distribution is X²₀.₀₁

If your starting salary is $35,000 and you receive a 6% increase at the end of every year, what is the total amount, in dollars,
aksik [14]

The starting salary is $35,000.

Salary is increased by 6% at the end of every year.

Nos of years worked = 16 years

Total salary earned in 16 years is given by An * (( 1+i )^n - 1 ) / i

Where, An = Present Salary = $35000

i = Increase in salary per year = 6% = 0.06

n = number of years = 16

= 35000 * ( 1.06 ^16 - 1 ) / .06

= 35000 * ( 2.54035 - 1 ) / .06

= 35000 * 1.54035 / .06

= 898538

Total earnings in 16 years is $ 898538

Angie is going to varnish the floor. Continued on other side of the page She needs 1 litre of varnish for 5 m2 of floor. There a
nirvana33 [79]

Answer:

No, she doesn't have enough varnish for all the floors.

Step-by-step explanation:

Area of the floor, A= 10x6-5x2=50 m^2

Since 5 m^2 required 1 liter of varnish.

So, the amount of varnish required for 1 m^2 = 1/5= 0.2 liters.

The amount of varnish required for 50 m^2 = 0.2X50=10 liters.

Now, as 1 tin has 2.5 liters of varnish.

So, the total amount of varnish available = 3x2.5=7.5 liters, which is less than the total requirement.

Hence, she doesn't have enough varnish for all the floors.

Nonamiya [84]

Answer:

y = x + 4

Step-by-step explanation:

Add on both sides:

-2x + 2y = 8

+2x            +2x

2y = 2x + 8

Divide the equation by 2:

2y = 2x + 8

/2     /2    /2

y = x + 4
