Answer:
2/13 or 0.15 , 1/4 and 5 /18 or 0.28
Step-by-step explanation:
20/26 ÷ 5 =?
10/13 ÷ 5 = 2/13 or 0.15
28/56 ÷ 2 =?
1/2 ÷ 2 = 1/4
75/90 ÷ 3 =?
5/6 ÷ 3 =5 /18 or 0.28
This has nothing to do with zero. It is not mentioned at all. If y = 0 then D would apply, but no such restriction is present. The answer is not D
There has to be 3 numbers multiplied together to use the associative properties of multiplication as in (2 * 3) * 5 = 2 * (3 * 5) . The order that we multiply does not matter.
The commutative property could be true, and it is you second best answer (believe it or not) but, 1 * y = y * 1 is kind of trivial. So don't pick B until we find out about A
This often shows up 1 * x is the same thing as x. This is called the multiplicative identity.

Answer:
a. The null hypothesis for this test is that the observed distribution is the same as uniform distribution
b. The degrees of freedom do you have for this test is 4
c. The calculated value of the test statistic is 9.250
Step-by-step explanation:
a. According to the given data we can conclude that the null hypothesis for this test is that the observed distribution is the same as uniform distribution.
b. In order to calculate the degrees of freedom do you have for this test we would have to make the following calculation:
degrees of freedom=k-1
degrees of freedom=5-1
degrees of freedom=4
c. In order to calculate the value of the test statistic first we have to calculate the frecuency expected as follows:
expected frecuency=total observed frecuency/total number of category
expected frecuency=1,000/5
expected frecuency=200
Hence, to calculate the value of the test statistic we have to calculate the following formula:
x∧2=∑(fo-fe)∧2/fe
=(185-200)∧2/200+(230-200)∧2/200+(215-200)∧2/200+(180-200)∧2+(190-200)∧2
=9.250
The calculated value of the test statistic is 9.250
8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.
Your answer would be 2.
