Answer:
y=1
Step-by-step explanation:
-3y+3+8y-24=6y+7-5y
5y+3=7+y
4y=4
y=1
You want to use this equation:
11.50-1.80-3.45=y, where y is his profit.
Since he spends 3.45 and 1.80, we're subtracting it, but he will gain 11.50 to mow the lawn.
Therefore, the answer is $6.25, or b).
For given Poisson distribution, <span>μ=8.
</span>P(x)=μ^x*e^(-<span>μ)/x!
so
P(4)=1.5^4*e^(-1.5)/4!= 0.04707 approx.</span>
Answer:
b
Step-by-step explanation:
thats the answer
Answer:
x = 90°
y = 40°
z = 40°
Explanation (Concepts) :
A straight line has total 180° angle. A square has 4 sides of each 90° angle. A triangle is build up of 180° interior angle.
Workouts:
z + 90° + 50° = 180°
z = 180° - 90° - 50°
z = 40°
=================
x + 90° = 180°
x = 180° - 90°
x = 90°
==================
50° + 90° + y = 180°
y = 180° - 90° - 50°
y = 40°
