Answer: 98.6 - x ≥ 2 or x - 98.6 ≥ 2
Step-by-step explanation:
Since, the normal temperature = 98.6° F
Also, the temperature that differs from normal by at least 2°F is considered unhealthy.
If the temperature is x degree F,
Then, we have two conditions,
Condition 1 : x > 98.6,
The difference between 98.6 and x = x - 98.6
Then the inequality be,
x - 98.6 ≥ 2
Condition 2 : x < 98.6
The difference between 98.6 and x = 98.6 - x
Then the inequality be,
98.6 - x ≥ 2
The answer will be: Y = -2/5x - 4
Slope intercept form: y= Mx+b
You find the slope (M) using: rise/run formula
You find (b) by looking at the y-intercept
53.24-34.99=18.25
$1 will buy 20 minutes of long distance calling
x$18.25 = 365 minutes @ $34.99
$132-$34.99=$97.01
20x97=1,940 minutes
minimum=365 minutes
maximum=1,940 minutes
Hope this helps.
The answer is C. 16/55 because P(Q and R) = P (Q) . P (R) (for independent events Q and R)
So, the prob. is 4/5 * 4/11 = 16/55 = D.
6.5 is the answer to your question
