Answer:
(C) 10.4 lb
Step-by-step explanation:
If Paul added each weight before adding, as you state, he got:
Apples 3.78 ⟶ 3.8
Peaches 2.12 ⟶ 2.1
Oranges 4.45 ⟶ <u> 4.4
</u>
Total 10.3 lb
If he did it this way, he did it <em>incorrectly</em>, and his answer isn't in the list of options, anyway. That's because his method introduces round-off errors.
The correct way is to add the numbers as given, and then round off <em>at the end</em>.
Apples 3.78
Peaches 2.12
Oranges <u> 4.45</u>
Total 10.35 ⟶ 10.4 lb
Note: When you drop a 5 f<em>ollowed by nothing</em>, you round off to the <em>nearest even number</em>.
Press that file☝️ it’s good lol
Answer:
6
Step-by-step explanation: You can set up the equation: = You square both sides to cancel out the squares which leaves you with = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with on both sides.
Answer:a. 0.13% b. 2.28%
Step-by-step explanation:
Let x denotes the useful life of batteries.
Given: months,
Since X is normally distributed.
The probability that batteries with a useful life of less than 38 months
The percent of batteries with a useful life of less than 38 months =0.13%
The probability that batteries will last longer than 68 months
The percent of batteries that will last longer than 68 months =2.28%
