Q2: x'1 = -1/3, x'2 =2
Q3: i dont get this one sry
Answer:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42
Step-by-step explanation:
Information given
n=1045 represent the random sample selected
X=502 represent the college graduates with a mentor
estimated proportion of college graduates with a mentor
is the value that we want to test
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true proportion is higher than 0.42, the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info we got:
The p value for this case would be given by:
For this case the p value is lower than the significance level so then we have enough evidence to reject the null hypothesis so then we can conclude that the true proportion is significantly higher than 0.42
Answer:
1/4 of them were rotten
rotten ones = 1/4 × 12 = 3
ones that weren't rotten = 12 - 3 = 9
Answer:
Part 1) The product of 3 and 2y-4x=8 is 
Part 2) The original equation in slope intercept form is 
Part 3) The new equation in slope intercept form is 
Step-by-step explanation:
we have

step 1
Find out the product of 3 and 2y-4x=8
Multiply both sides by 3

Apply distributive property both sides

step 2
Find out the original equation in slope intercept form
The equation of the line in slope intercept form is

we have

Solve for y
That means ----> Isolate the variable y
Adds 4x both sides

Divide by 2 both sides

Simplify

step 3
Find out the new equation in slope intercept form
The equation of the line in slope intercept form is

we have

Solve for y
That means ----> Isolate the variable y
Adds 12x both sides

Divide by 6 both sides

Simplify

1. 5/y=2/3x +3
2. y= 7/1-4
3. y=2/5x8
4. y=-3/4 +1 I could be wrong but I think this is right
