Answer:
a. Chi-square test of independence
Step-by-step explanation:
The chi square statistics is also used to test the hypothesis about the independence of two variables each of which is classified into a number of categories or attributes.
In the given problem the Equal , more or less are the attributes.
The goodness of fit test is applicable when the cell probabilities depend upon the unknown parameters provided that the unknown parameters are replaced with their estimates and provided that one degree of freedom is deducted for each parameter estimated.
Answer:
Hello!
answer: a = 5
b = 8
Step-by-step explanation:
since we are given 1 side of the parellogram we can use that to figure out the rest! parellograms will add up to 360 degrees since 1 angle is 115 that means the other will be 115 115 + 115 = 230
360 - 230 = 130 since there 2 angles across from each other they will both equal the same so 130 ÷ 2 = 65 so both of these angles will have to equal 65 because 65 + 65 + 115 + 115 = 360 a = 5 because 14 x 5 = 70 and 70 - 5 = 65 b = 8 because 8 x 8 = 64 and 64 + 1 = 65 Hope this helps you understand!
Your total volume would be 150 cubic feet and the weight would be .1
Answer:
x = -1, 0, 2
Step-by-step explanation:
p(x) = 5x³ − 5x² − 10x
Factor the greatest common factor:
p(x) = 5x (x² − x − 2)
Now factor the quadratic. You can use the AC method, the quadratic formula, the rational root test, or trial and error.
p(x) = 5x (x − 2) (x + 1)
Finally, set each factor equal to 0 and solve for x.
5x = 0 → x = 0
x − 2 = 0 → x = 2
x + 1 = 0 → x = -1
The did not combine like terms correctly.
Step SHOULD'VE went like this:
20-26=-6 & -34+60=26
-6+9=3
3=26
Divide!
3÷3=0 ⇒26÷3=8.6666.....
or (rounded)
the answer would be 8.7
