Answer:
There is difference in the scores of males and females
Step-by-step explanation:
Given that a professor teaches a certain section of material using a lot of examples with sports and cars to illustrate. He is concerned that this may have biased his instruction to favor male students
Since simple variances are unequal, we can do t test for comparison of two means with unequal variances
Group Group One Group Two
Mean 84.00 78.00
SD 4.00 8.00
SEM 1.26 2.53
N 10 10
The mean of Group One minus Group Two equals 6.00
95% confidence interval of this difference: From 0.06 to 11.94
t = 2.1213
df = 18
standard error of difference = 2.828
The two-tailed P value equals 0.0480
Since p <0.05 we reject null hypothesis
There is difference in the scores of males and females
Solution: -3(-5) + 2(-5) -1= 4
Explanation:
Since the value of x is given you have to plug in or substitute it in for x in the equation. The work is shown above.
Answer:
The correct option is d.
Step-by-step explanation:
The given equations are
.... (1)
.... (2)
In equation 2, multiply both sides by 2.
.... (3)
Now add equation (1) and (3).
Divide both sides by 5.
Put this value in equation (2).
Therefore the solution of the system of equation is (2.4,0.2) and the system has only one solution. Option d is correct.

Answer:
Simplified version: 10x^5 - 1x^4 + 2x^3 - 6
Step-by-step explanation:
Since your birthday is 10/1/2006 we can use 1012006 as our digits.
We can make a random polynomial: 10x^5 - 1x^4 + 2x^3 + 0 x^2 + 0x - 6
(since 0 are meaningless we can simply this further into the below equation)
10x^5 - 1x^4 + 2x^3 - 6
