short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so

Answer:
-14
Step-by-step explanation:
step 1:
Subtract 11 from both sides.
y+11−11<−3−11
y<−14
Answer:
(a) 13 ounces.
(b) 1.732 ounces.
(c) 0.5
(d) 0.33
Step-by-step explanation:
Given : The amount of water dispensed follows a continuous uniform distribution from 10 ounces to 16 ounces. So, a=10 and b=16.
(a) The average amount of water dispensed by the machine = (a+b)/2 = (10+16)/2 = 13 ounces.
(b) The standard deviation of the amount of water dispensed = = √36/12 =√3 = 1.732 ounces.
(c) P (13 or more ounces will be dispensed in a given glass) = = = 0.5
(d) P (between 12 and 14 ounces will be dispensed in a given glass) = ( here a=12 and b=14.) = = 0.33
Answer:
7 1/2 m
Step-by-step explanation:
C = πd
in this problem, d = 15 which means that r = 15/2 or 7 1/2
