When the 10 is to a negative power you move the decimal to the left. in this case its 5 spots. i believe your answer is .00005003
Answer:
(xy - 4)(xy + 4).
Step-by-step explanation:
The is the difference of 2 squares.
a^2 - b^2 = (a - b)(a + b: so we have:
x^2y^2 - 16 = (xy - 4)(xy + 4)
The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Carson is going on a work trip. He will get reimbursed for his expenses for driving his own car.
He will get a flat rate of 30, plus $1.25 per mile (m) he drives.
The equation formed;
R = 30 + 1.25m
The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.

Answer:
5
Step-by-step explanation:
Given :
Observed values = 5, 10, 15
Expected freqencies = 10
χ² = Σ(observed - Expected)² / Expected
χ² = (5-10)²/10 + (10-10)²/10 + (15-10)²/10
χ² = 25/10 + 0/10 + 25/10
χ² = 2.5 + 0 + 2.5
χ² = 5
