Answer:
2
Step-by-step explanation:
PEMDAS says to do the equations in parentheses first
(14-4) = 10
PEMDAS then says to do multiplication or division, whichever comes first in the equation, which is multiplication in this case
(10)2 = 20
20 ÷ 10 = 2
Answer:
The answer is C
Step-by-step explanation: because it is reflecting and is backwards.
Answer:
x = 2.25, y = 2.5
Step-by-step explanation:
-2x + 2y = -2 .............equ (1)
2x + 3y = 12 .............equ (2)
equ (1) + equ (2)
-2x + 2y = -2
+ 2x + 2y = 12
=> 0 + 4y = 10
=> 4y/4 = 10/4
=> y = 2½
Substitute for y in equ (2)
i. e, 2x + 3y = 12
=> 2x + 3(10/4) =12
=> 2x + 30/4 = 12
=> 2x = 12 - 30/4
=> 2x = (48 - 30)/4
=> 2x = 18/4
=> 8x = 18
=> x = 18/8
=> x = 2^2/8 or 2.25
x = 2.25, y = 2.5

Answer:
a. 0.26
b. 0.7
c. 0.38
Step-by-step explanation:
For a)
For sponsored studies: 62 % found the products favorable. The percentage is 0.62.
For non-sponsored studies 46% found the products favorable. The percentage is 0.46
Total probability = P(A) × P (B)
= 0.46 × 0.62
= 0.2604
For b)
Probability for the food industry = 0.7
For c) 1 - ( 0.62) = 0.38
