Answer:
z = -2.85
Step-by-step explanation:
Since the number of nuts per can is normally distributed:
Mean number of nuts (μ)= 500 nuts
Standard Deviation (σ)= 20 nuts
X = 443 nuts
For any given number of nuts X, the z-score is given by:
The z-score for this can of nuts with 443 nuts is -2.85.
Let Paul's house be at the origin of a coordinate grid. then Mary lives at (-6,-9) and Benjamin lives at (7,3). using the distance formula for these two points gives us d=√(-6-7)² + (-9-3)².
d=√169+144 or√313 miles, or about 17.69 miles.
Answer:
The sports shop has 21 part-time employees.
Step-by-step explanation:
Solution:
What is 25% of 84?
.Y is 25% of 84
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 25% * 84
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 84
Y = 21
Or another quicker way....
50% is half of the whole, and 25 is half of 50.
84/2/2
equals 21 too, I don't recommend to use it as row form.
Step-by-step explanation:
a · b = (4)(3) + (5)(6)
