its is the same as multiplying normally .
For example 1-2-3-4-5-6-7-8- 2 times 2
you just take the starting number (2) and times it by the other number (2) and youll get 4
The quantities in the proportion you give add to 16 pounds, of which 2 pounds are cement. That is, cement constitutes 1/8 of the total weight.
For each yard of concrete, 4000 lb/8 = 500 lb of cement are used.
For 12.5 yards of concrete, 12.5 * 500 = 6,250 pounds of cement will be used.
_____
"yard" in this case is shorthand for "cubic yard".
Answer:
Therefore
, A=184
Step-by-step explanation:
Given function is

where T(t) is the temperature in °C and t is time in minute and A and k are constants.
She noticed that after 18 minutes the temperature of the pie is 138°C
Putting T(t) =138°C and t= 18 minutes


.....(1)
Again after 36 minutes it is 184°C
Putting T(t) =184°C and t= 36 minutes


.......(2)
Dividing (2) by (1)


Taking ln both sides




Putting the value k in equation (1)





⇒A= 184.
Therefore
, A=184

Critical value for 90% Confidence interval : 
a) Confidence interval :


Hence, a 90% confidence interval for the proportion of Americans who decide to not go to college because they cannot a ord it : 
b) Margin of error : E=1.5%=0.015
Formula for sample size : 
For p =0.48 , we have

Hence, the required sample size to survey = 3002
Answer:
The answer to this question can be defined as follows:
Step-by-step explanation:
In the first point:
Yes, the Finite Floating Point Structures are considered Where 


In the second point:
There is no device with a finite floating-point since the right side is
This equality never happens, then, with the rational numbers (
and
is rational).
