Answer:
Step-by-step explanation:
a) H0:
Ha:
(Two tailed test at 5% significance level)
b) n=30
Mean difference =
Std error of mean =
b) Test statistic t = mean diff/std error = -1.552
df = 30-1 =29
p value=0.0657
c) Since p > 0.05 our signi. level, we accept null hypothesis.
There is no significant difference between the means.
d) Using critical value we find that test statistic is > critical value left
So accept H0
2x - 4y = 8 → -4y = -2x + 8 → y = - 2
We know the slope (m) = 4, need to find y-intercept (b)
y = 4x + b
- 2 = 4x + b
- 2 = 4(6) + b
3 - 2 = 24 + b
1 = 24 + b
-23 = b
Equation: y = 4x - 23
Answer: C
Answer:
$100.4
Step-by-step explanation:
Compound Interest Formula:
A = P1 +
=> A = 100 x ( 1 + )^1 = 100.4 (If they asked ... interest rate ... per year, if not then depends - most likely to be days and therefore you will need to change 1 year = 365 days and you will also need to change 1 in the formula above to 365, then you will get the right ans)
