Answer:
(-2,-2)
Step-by-step explanation:
you would be going down the cooridante plane so that would only change the y value.
Answer:
D. Since the P-value is less than 0.05, we reject the null hypothesis and conclude that there is a difference in the softness level achieved by the two processes.
Step-by-step explanation:
H0: μ1 - μ2 = 0
Ha: μ1 - μ2 ≠ 0
Test statistic t = 3.328, P-value = 0.0014, DF = 69.97
The Critical value for df = 69.97 is t ( ∝/2) (df): ±1.9945
The calculated t value falls in the critical region so H0 is rejected
As P - value is less than significance level H0 is rejected .
It is a two tailed test and the P - value is0.0014 which is less than 0.05 the significance level.
This means the softness achieved by Process A is considered to be not equal to the softness achieved by the Process-B .
Only choice D is correct.
Answer:
So, The answer would be 1=k
Step-by-step explanation:
My step is to make a T-chart, as u make it put X on one side and Y on the other
So what i did was i put 0 for both of them because it had start at 0
then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k
And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k
So you would put the answer as 1
thats it Answer-1

Answer:
Speed of Jet in Still Air = 265 miles per hour
Speed of Wind = 22 miles per hour
Step-by-step explanation:
Let x be speed of jet
and c be speed of wind
We know D = RT, where
D is distance
R is rate
T is time
For first leg:
1435 miles in 5 hours, the rate is:
Rate = 287 mph
For second leg:
1215 miles in 5 hours, the rate is:
Rate = 243 mph
So 287 is with wind and 243 against wind, thus we can write:
x + c = 287
x - c = 243
Adding gives us:
2x = 530
x = 265 miles per hour [still rate]
Speed of wind:
x + c = 287
265 + c = 287
c = 22 miles per hour [speed of wind]
It’s just like solving a positive fraction find a common denominator and Add or subtract
