Hi,
The like terms are 2xy, -xy and (1/2)xy, since they have the same variables and powers.
The z-score is given by:
z=(x-μ)/σ
but
x-μ=52
thus
z=52/√84681
z=0.1787
Thus:
P(X≤52)=0.9633
<span>4(c+2)= -28
Use distributive property
4c+8=-28
Subtract 8 from both sides
4c=-36
Divide 4 on both sides
Final Answer: c=-9</span>
1/3 is equal to 4/12.
1 goes into 3, 3 times, and 4 goes into 12 three times. Therefore 4/12 is also 1/3.
The range of a relation is the possible output values, the y-values.
