Studies show that people who live in very cold climates have a 30% chance of getting influenza and a 15% chance of getting appen
il63 [147K]

Answer: The probability a person has both diagnoses = 4.5%

Step-by-step explanation:

Given: Chances of getting influenza = 30% = 0.30

Chances of getting appendicitis  = 15% = 0.15

Since both the events are independent , so the probability a person has both diagnoses will be

P(influenza and appendicitis) =P(influenza) x P(appendicitis)

=0.30\times0.15\\\\=0.045\\\\=4.5\%

Hence, the probability a person has both diagnoses = 4.5%

(2a+b)^2÷(3b-1) when a= -2 and b=5
WINSTONCH [101]
Evaluate (2 a + b)^2/(3 b - 1) where a = -2 and b = 5:
(2 a + b)^2/(3 b - 1) = (5 - 2×2)^2/(3×5 - 1)

3×5 = 15:
(5 - 2×2)^2/(15 - 1)

 | 1 | 5
- | | 1
 | 1 | 4:
(5 - 2×2)^2/14

2 (-2) = -4:
(-4 + 5)^2/14

5 - 4 = 1:
1^2/14

1^2 = 1:

Answer: 1/14

Use the subtraction property of equality to complete this statement. If y = 3 and 8x + y = 12, then
Over [174]
8x + y = 12 (substitute 3 for y) 
<span>8x + 3 = 12 </span>
<span>8x = 9 </span>
<span>x = 9/8 </span>

<span>If y = 3 and 8x + y = 12, then x = 9/8.

HOPE THIS HELPS!!</span>
