To solve this we use the z statistic. The formula for z
score is:
z = (x – u) / s
where x is the sample value = less than 16, u is the
sample mean = 16.1, s is standard dev = 0.1
z = (16 – 16.1) / 0.1
z = - 1
From the standard distribution tables at z = - 1,
P (z = -1) = 0.1587
<span>So about 15.87% is underweight.</span>
Answer:
19(200+4d)+25(50+5d)
Step-by-step explanation:
To represent this as an expression, we could multiply the amount of each booth by their own equations and expenses. The expression for a food booth is 200+4d, since they charge 200 at the start and add 4 dollars for every day.
The expression for the game booth is 50+5d, since they charge 50 initially and charge 5 for every day.
Now we can just multiply the expressions by their amount and add them together.
19(200+4d)+25(50+5d)
There's your expression!
Hope this helps :D
