Answer:
k= 20
Step-by-step explanation:
You start with this equation:
k-16=4
Add 16 on both sides.
k=4+16
Simply.
k=20
If you want to check your answer, you can just plug 20 into where k is back into the equation:)
Hope this helps!
Answer:
(3,0) & (-6,3)

Lol I just answered the same question minutes ago. Here is the answer I gave him/her.
Total Cost : 1800
12 dollars * 16 hours = 192 dollars earned
0.2 percent * 192 = 38.4 dollars saved
A.She earns 192 dollars every week
B. she will save 38.4 dollars * 7 weeks = 268.8 dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. 30.1 days * 38.4 = 1,155.84 dollars every month.
D. it will take her about 2 months to save the money. To be exact: 1.6 months.
Hope this helped!
Answer:
4.01% probability that the battery will break down during the warranty period
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
a. What is the probability that the battery will break down during the warranty period
Warranty of 2 years = 24 months. So this is the pvalue of Z when X = 24.
has a pvalue of 0.0401
4.01% probability that the battery will break down during the warranty period
Answer:
32
Step-by-step explanation:
To compare how much more Lola hiked we need the miles that each one hiked.
Elton hiked 16 miles each day for 12 days, the total amount of miles he hiked we can found by multiplying 16 by 12:
16miles(12) = 192 miles
Lola hiked 14 miles each day but for 16 days, so the total amount of miles she hiked can be found by multiplying 14 by 16:
14miles(16days) = 224
The difference of miles we found by subtracting 192 (elton's miles) from 224 (lola's miles)
224 - 192 = 32
