Answer:
So , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.
Step-by-step explanation:
The properties of parallelograms are as follows:
i) the diagonals of a parallelogram bisect each other
ii) opposite sides are congruent
iii) opposite angles are congruent
iv) consecutive angles are supplementary
v) the diagonals are angle bisectors only if all the sides of the parallelogram are equal.
So , the correct option is the diagonals are angle bisectors which is not a characteristic of all parallelograms.
Answer:
The value of the test statistic z for this hypothesis test is -2.79
Step-by-step explanation:
Consider the provided information.
To calculate the test statistic use the formula:
Where, z is Test statistics, n is Sample size, p₀ = Null hypothesized value and = Observed proportion.
p₀ = 0.50
Thus 1-p₀= 0.50
42% responded that if they had a cell phone, thus
The sample size is 305.
Substitute the respective values in the above formula.
Hence, the value of the test statistic z for this hypothesis test is -2.79
Answer:
3 + -5 = -2 because adding a negative is basically subtracting.
So 3 + -5 = 3 - 5 = -2
