Answer:
C. The standard deviation of the sample mean will be smaller than the population standard deviation.
Step-by-step explanation: Standard deviation is described as the square root variance,it is a Mathematical and statistical analysis tool used to understand the variation of treatments or values around the Mean.
The higher the Population the more the chances for deviation from the Mean, samples are always less than the entire population so the chances for variations will be less with sample than with the population.

Step-by-step explanation:
1) 3 gallons=36 miles
16 gallons=?
so it will be
or you can do like this
1 gallons=12 miles so if 16 gallons multiply with 12 it will be 192
2)2 hours=$28.50
? =$99.75
so it will be
so it will be 7 hours
3) 4.5 km= 5 hours
? =60 hours
the answer will be 54 kilometer
4) $9.60=3cm
$22.40=?
7 cm
5) $145.50=50 miles
$552.90=?
190 miles
6)$239.85=359
$1.95=?
2.92 liter
7)
220=60 hours
?=3 hours
11 miles
8)1 gallon= $17.50
8.2 gallon=?
$143.50
9)7cm=2 minute
? =13 minute
45.5 cm
10)17=4 acres
? =244 acre
1037 kg
11) 1= $2.85
4.4=?
$12.54
12)
$2.50=5 oz
$32.50=?
65 oz
By determining the length of TV using TV^2=15^2+10^2-2(15)(10)cos80, and then determining the value of x using 15^2=TV^2+10^2-2(TV)(10)cosx.
Answer:
≈9.64 gallons
Step-by-step explanation:
To solve, we can figure out how many quarts are in a minute and use that to figure out how many quarts are in an hour. Then, we can convert quarts to gallons.
4.5 quarts = 7 minutes
First, we can find how many quarts equal 1 minute. To do this, we can divide both sides by 7 because anything divided by itself equals 1
4.5/7 quarts = 1 minute
Next, we want to figure out how many quarts go into 60 minutes, or 1 hour. To do this, we can multiply both sides by 60 because 1 * 60 = 60
4.5 * 60 / 7 quarts = 60 minutes = 1 hour
We now know how many quarts are in an hour, so we can now convert quarts to gallons
4 quarts = 1 gallon
divide both sides by 4
1 quart = 1/4 gallons
To get from quarts to gallons, we can divide by 4, so we have
(4.5 * 60 / 7)/4 = 4.5 * 60 / 28
≈9.64 gallons
