Answer:
The correct answer is C.
Step-by-step explanation:
There are 8 slots on Spinner B.
3 of those slots have squares.
Hence out of all the slots, 3/8 of them have squares.
Hope this helps:) Goodluck!
The mid point of DE is (3,-1)
This can be found with Pythagorean Theorem
The length of “a” is 6. The length of “b” is 4.
The length of DE is ≈ 7.21. The midpoint of this value is found at coordinates (3,-1)
Answer:
Parallelogram
Step-by-step explanation:
All of the choices are parallelograms.
Hope I helped!
Placed them equal to each other.
3x + 6 = 4x - 2
6 (+2) = 4x (-3x)
8 = x
plug in x to both of the expressions
3(8) + 6 = 24 + 6 = 30
4(8) - 2 = 32 - 2 = 30
True
x = 8
hope this helps
B is wrong, because you do not set them equal to 180 ( you set them equal to each other). Next, it is wrong, because they messed up the end too.
hope this helps
Answer:
Test = 17.143 ;
Pvalue = 0 ;
Reject the Null ;
(-0.028 ; - 0.022) ;
We conclude that content are different.
Step-by-step explanation:
Given that:
μ1 = μ
n1 = 36 ; n2 = 36
x1 = 0.78616 ; x2 = 0.81111
s1 = 0.04444 ; s2 = 0.00752
Test statistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(0.78616 - 0.81111) / √(0.00444²/36 + 0.00752²/36)
- 0.02495 / 0.0014554
= 17.143
Pvalue :
Z < 17.143
Pvalue = 0
Since Pvalue < α ; Reject the Null
The confidence interval using a confidence interval calculator is (-0.028 ; - 0.022)
Since the interval does not contain Zero ; then we reject the Null and conclude that the content are different.
