Answer:
Option B
Step-by-step explanation:
As per the question:
The variance of the 48 Econ 202, = 16 inches
The variance of 63 Econ 203 = 14 inches
Now, to test the variance of two populations:
For 48 Econ 202:
For 63 Econ 203:
On comparing the two, the test statistics is given by;
F = 
F = 
Answer:
A. How much flour did she use for both cakes?
1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
3 17/20 lb
Step-by-step explanation:
Penny used 2/5lb. Of flour to bake a vanilla cake. She used another 3/4lb. Of flour to bake a chocolate cake
A. How much flour did she use for both cakes?
We solve the above question by adding up the pound of flour used for both cakes.
2/5lb Of flour + 3/4lb Of flour
Lowest common denominator = 20
= 8 + 15/20
= 23/20
= 1 3/20 lb flour
B. If she started with a 5lb. Bag, How much flour does she have left?
This is calculated as:
5 lb - 1 3/20 lb
= 3 17/20 lb
Molly spends 14.10 more on her scooter. I did this by doing 26.99 - 12.89.
The surface area of a sphere is: 4pr^2
(4p(36^2)ft^2)(gal/160ft^2)
(5184p ft^2)(gal/160ft^2)=32.4p gal which is approximately:
101.78 gal
So the company must purchase 102 gallons of paint.
Answer:
Area of resulting triangle will be 900 
.
Step-by-step explanation:
When sides of any polygon if scaled by a factor of k
then area is scaled by 
According to the above statement
therefore here in the question since area of original triangle was 36
and both base and height are scaled by a factor of 5.
therefore area of scaled triangle will be 
times of the original
that is 25 x 36 which gives 900
So area of resulting triangle will be 900
