Answer:
B changes at x = +2 where the others change at x = -2
Step-by-step explanation:
Answer:
Opposite sides are congruent (AB = DC).
Opposite angels are congruent (D = B).
Consecutive angles are supplementary (A + D = 180°).
If one angle is right, then all angles are right.
The diagonals of a parallelogram bisect each other.
Each diagonal of a parallelogram separates it into two congruent triangles.
Step-by-step explanation:
Answer:
a 0.20
Step-by-step explanation:
The standard error of the mean can be calculated using the formula
SE=
where
- s is the population standard deviation of the time spend on the computer (1.4 hours)
- N is the sample size of the data collected. (49)
Using the numbers SE=
=0.20
First, find the length of the third side of the piece of jewelry by using the Pythagorean Theorem.
Then, find the perimeter of the piece of jewelry by adding all the sides. And after doing all that your total answer should be 36mm
Cost/amount is constant
1235/95=x/285
cross multiply or time both sides by (95 times 283)
351975=95x
divide oth sies by 95
3705=x
the cost is $3705
