Answer:
b
Step-by-step explanation:
1/5 is equal to 20% =.2 it stops there
Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean
15 sandwiches
3 tomatoes= 5 sandwiches.
So if there's 9, that makes 3 groups of 3 tomatoes which would make 3x5 or 5+5+5 ;-;
15.
Subtract 14x from both sides. Then divide both sides by 19

The equation is now in slope intercept form y = mx+b
m = -14/19 is the slope
b = 20/19 is the y intercept
