Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
Answer:
[0.9 months, 32.69 months]
Step-by-step explanation:
The mean is
The standard deviation is
Now, we have to find two values a and b such that the area under the Normal curve with mean 16.8 and standard deviation 8.1092 between a and b equals <em>95% = 0.95
</em>
Using a spreadsheet we find these values are
a = 0.906
b = 32.694
<h3>(See picture)
</h3>
and our 95% confidence interval for the mean number of months elapsed since the last visit to a dentist for the population of students participating in the program rounded to two decimal places is
[0.9 months, 32.69 months]
Answer:
(i) A = {1,3}
(ii) B = {1,100}
Step-by-step explanation:
1,2,3,100
Odd no.s are: 1 & 3
Perfect squares are: 1 & 100
Answer:
Typically the answer is Graph the y intercept because when you do slope intercept you cant always start with the origin unless you don't have a b to base it off of.
V=(1/3)(area of the base)(<span>altitude)
V=</span>(1/3)(6²)(6)= 72 m³
Hope this helps :3
