From the z-table and at p67 or 0.67 (the decimal values in the table),
Z =0.44
See the attached photo (at the point where 0.6700 appears)
Multiply 1/5 and 1/4 so that everything has a common denominator of 200.
1/5*40/40 = 40/200
1/4*50/50 = 50/200
Answer:
2
Step-by-step explanation:
3x5 is 15 and 4x5 is 20
Answer:
Step-by-step explanation:
Store A price is 20x-7
store B price is 4(5x+7)
Where x represents the number of items.
Now, observe that the coefficient of both expressions is 20, because 4(5x+7)=20x+7
Remember that the coefficient of the x-variable is always the constant rate of change. Also, the given expressions can be expressed as linear functions
y=20x-7
y=20x+28
Observe that both Stores have already the same rate, which is 20.
Therefore, they have the same rate at any number of items dry cleaned.
What they have different is their initial condition, -7 and +7 respectively, but the rate is the same..
Answer:
B. Angle E=43
Step-by-step explanation:
Angles DEF are = to 73 degrees
73-43=30/2=15
15+15+43=73
