SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses
Step 2: T-test analysis
Step 3: t-test with the significance level
Step 4: Comparing
So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.
Answer and Step-by-step explanation:
1. slope intercept
2. point-slope form
3. standard
Explanation:
1.
A <u>slope intercept form</u> equation is when it's set up as y = m x + b
m = slope
b = y-intercept
2. <u>A point-slope form</u> is when a line passes through a point
and the equation is set up as y
−b = m (
x−a)
m = slope
(a, b) A point that the line passes through
3. <u>standard lope form</u> is when the equation is set up as
Ax + By = C
Answer:
34347
Step-by-step explanation:
Use the formula s=p(1+r/k)^kt
p=30000
r=7% (interest)
k=1 (because of per annum)
t= 2 (years)
Hence: 30000(1+0.07/1)^1(2) = 34347
Let's start with the blue states. Out of 50 states, 28 of them were blue.
Therefore, the fraction would be 28/50. Let's reduce it.
28/50=14/25 --> these are the lowest terms for this fraction
Use a calculator to find the decimal solution --> 14/25= .56
Now, let's do the red states. Out of the 50 states, 22 of them were blue.
22/50=11/25 --> lowest terms
Use a calculator --> 11/25= .43
Answer:
120 pages can be printed in 1 hour.
Step-by-step explanation:
First divide 36 by 18 to figure out how many pages can be printed in a minute.
Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.
Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.
Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.
Hope this helps!
