The sample proportion is a point estimate of the population proportion. Therefore we need to convert the given percentage to a decimal fraction to find the best point estimate.
35/100 = 0.35
The best point estimate is 0.35.
Answer: 12 gallons
Step-by-step explanation:
Use proportion to estimate how much gas she needs for 204 miles.
10:120=x:204
204*10=120x
x=2040/120
x=17 gallons
For 204 mile trip Trina needs 17 gallons of gas. She has 5 gallons.
17-5=12
She will need 12 gallons of gas.
Answer:
19.79 ft
Step-by-step explanation:
Given data
We are given that the dimension of the room is
Length= 14ft
Width= 14ft
Required
The Diagonal of the room
Applying the Pythagoras theorem we have
D^2= L^2+W^2
substitute
D^2= 14^2+14^2
D^2= 196+196
D^2= 392
D= √392
D= 19.79 ft
Hence the distance from one corner to the other is 19.79 ft
