Answer:
9
Step-by-step explanation:
if she has 14 and then spends 5 she will have 9. 4-5=9
Slope =change of y over change of x
(2, −5) and (4, 1)
M= 1-(-5)/4-2
M=6/2
M=3
So the slope is 3.
If you need the equation
Y=mx+b
(4, 1)
1= 3(4)+b
1=12+b
1-12=b
-11=b
So equation
Y=3x-11
Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
Answer:
A) H0: μ = 11 vs. Ha: μ > 11
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
The null hypothesis is that the average number of headaches per student during a semester of Statistics is 11.
H0: μ = 11
The alternative hypothesis is that the average number of headaches per student during a semester of Statistics is greater than 11.
Ha: μ > 11
