Answer:
The p value is given by:
For this case the p value is higher than the significance level of 0.01 so then we have enough evidence to FAIl to reject the null hypothesis and we can't conclude that the true proportion is significanctly higher than 8%
Step-by-step explanation:
Information given
n=80 represent the random sample taken
X=9 represent the number fo items undefilled
estimated proportion of underfilled items
is the value that we want to test
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true proportion of items underfilled is higher than 0.08 and we got.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given by:
The p value is given by:
For this case the p value is higher than the significance level of 0.01 so then we have enough evidence to FAIl to reject the null hypothesis and we can't conclude that the true proportion is significanctly higher than 8%
Answer:
Step-by-step explanation:
I would have thought the answer would be whole numbers...
using top line....
5x-5y + 7x-15 = 180 (that is a line)
12x - 5y = 195
using bottom line
4x+ 4y +2x+ y = 180
6x + 5y =180
~~~~~~~~~~~~~~~~~~
12x - 5y = 195
6x + 5y =180
(fives cancel)
18x = 375
x = 20.83
y= 11
Answer:
Below
Step-by-step explanation:
First I found the area of the portion that extends off (if that makes sense??)
It is a triangle, so use A = bh/2
A = (2)(6) / 2
= 6 cm^2
Next I found the area of the rectangle using A = LW
A = (6)(3)
= 18 cm^2
Total area = 18 + 6
= 24 cm^2
Hope this helps! Best of luck <3
Answer:
The length of the width is 1
Step-by-step explanation:
Since we are not finding the hypotenuse and we are given it, we have to rearrange the a² + b² = c² equation because that equation is to find the hypotenuse of a right - angled triangle and we are not asked to find the hypotenuse but the width so
a² + b² = c²
→ Substitute in the values
( √3 )² + b² = 2²
→ Simplify equation
3 + b² = 4
→ Minus 3 from both sides to isolate b²
b² = 1
→ Square root both sides to isolate b
b = 1
