Create the following proportion:
=
Cross multiply.
10.5 x 1 = 10.5
4.75 x X = 4.75x
4.75x = 10.5
Divide both sides by 4.75x.
10.5/4.75 = 2.2

Answer:
There is sufficient statistical evidence to suggest that the average weight of the ground beef packaged in small trays is 1 pound
Step-by-step explanation:
Here we have to perform a t-test
Mean = Sample mean = 1.04 lb
μ = Population mean = 1 lb
s = Standard deviation of 0.19
n = Sample size = 45
Null hypothesis H₀ = 1
Alternative hypothesis Hₐ > 1
Therefore from
we have
t = 1.412
Critical t at 5% confidence level = 1.68
at 5 % confidence level we obtain the probability P is;
P = 0.0825 > 0.05 Therefore we accept our null hypothesis that the average weight of ground beef per pack is 1 pound.
Answer:
Speed = 1050 meters per seconds
Distance =10500 meters
Step-by-step explanation:
Car traveling at a speed of 63 kilometers per hour
Let us convert this into meter per second
Speed = kilometers per hour
Speed = --------(A)
1 kilometer = 1000 meters
1 hours = 3600 seconds
Replacing them in (A)
Speed =
Speed = meters per seconds
Speed = meters per seconds
Speed = 1050 meters per seconds
Distance = speed x time
Speed = 1050 mt per sec
time = 10 sec
Distance = 1050 x 10 = 10500 meters
