Answer:Angles 1 and 3 are vertical angles
Step-by-step explanation:
Same strategy as before: transform <em>X</em> ∼ Normal(76.0, 12.5) to <em>Z</em> ∼ Normal(0, 1) via
<em>Z</em> = (<em>X</em> - <em>µ</em>) / <em>σ</em> ↔ <em>X</em> = <em>µ</em> + <em>σ</em> <em>Z</em>
where <em>µ</em> is the mean and <em>σ</em> is the standard deviation of <em>X</em>.
P(<em>X</em> < 79) = P((<em>X</em> - 76.0) / 12.5 < (79 - 76.0) / 12.5)
… = P(<em>Z</em> < 0.24)
… ≈ 0.5948
Answer: 50 cents
Step-by-step explanation:
Company charges 8 cents per call and the call in question is 3 minutes. Cost is;
= 3 * 8
= 24 cents
Company however stipulates that a call is 8 cents per minute or a 50-cent minimum charge per completed call, whichever is greater.
<em>50 cents is greater than the per minute total charge of 24 cents so the cost will be 50 cents.</em>
The answer is: [C]: " 3.200 * 10⁷ h " .

Explanation:
________________________________
19.2 * 10⁸ min * (1 hr / 60 min) ;
= (19.2 * 10⁸)
_______________ ;
60
_____________________________
Divide EACH SIDE of the fraction by "10" ; to get:
___________
(19.2 * 10⁷)
_______________ ;
6
<span>______________________________
</span>⇒ (19.2) ÷ (6) = 3.2 ; so rewrite as:
_________________________________________________________
3.2 * 10⁷ ; which corresponds with:
