1.
-2x = 10
x = 10/(-2)
x = -5
2.
1/2 x = 5
x = 5 * 2
x = 10
3.
5x = -20
x = -20/5
x = -4
4.
9x = 36
x = 36/9
x = 4
Answer:
Implied though not plainly expressed, or said metaphorically not litteraly
Step-by-step explanation:
this is definiton from google combined with mine hope this helps.
Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.
Answer:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
Step-by-step explanation:

1. Null and alternative hypothesis

2. Significance level

Freedom degrees is given by:

For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:

3. Test statistic



In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if 

Conclusion:
It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.
