.53= 53/100
53/100 cannot be simplified so the answer is 53/100
Answer:
The team won 32 games.
Step-by-step explanation:
x = games won
y = games lost
z = total games = 40
x = 4y <em>Won 4 times as many games as it lost</em>
x + y = 40 <em>Games won + games lost = Total games played</em>
4y + y = 40 <em>Sub 4y in for x, as established previously</em>
5y = 40
y = 8
x = 4y
x = 4(8)
x = 32
The team won 32 games.
Answer:
f(n) = 100·4^(n-1)
Step-by-step explanation:
The given function c(n) is apparently the multiplier for n days. Its value is 1 for n=1, so we simply need to multiply c(n) by 100:
f(n) = 100·c(n) = 100·4^(n-1)
Answer:
Step-by-step explanation:
They tell you the answer in the picture. Angle DAB is the lower left vertex, so its measure is 80°
Angle BCD is the upper right vertex.
Answer:
The sample proportion 
is within 0.03 of the true proportion of customers who are under age 21 is 0.803
Step-by-step explanation:
Total no. of customers = n = 400
We are given that the true population proportion of customers under age 21 is 0.68.
So, p =0.68
q=1-p=1-0.68=0.32
Standard deviation =
We are supposed to find the probability that the sample proportion is within 0.03 of the true proportion of customers who are under age 21 that is , what is the probability that is between 0.68 - 0.03 and 0.68+ 0.03
Using Z table
Hence the sample proportion is within 0.03 of the true proportion of customers who are under age 21 is 0.803
