2.75=2 3/4 because you would say 2.75 as two and seventy-five hundredths. Seventy-five hundredths is just like 3 quarters out of 4 because 1 quarter=25. 2=50. 3=75. So, 2.75 as a fraction in simplest form is 2 3/4.
Hope I helped:D
Answer:
A
Step-by-step explanation:
Given
y - 3x = - 14
Rearrange expressing y in terms of x by adding 3x to both sides
y = 3x - 14, that is
g(x) = 3x - 14 → A
Answer:
Step-by-step explanation:
We want to determine a 90% confidence interval for the mean amount of time that teens spend online each week.
Number of sample, n = 41
Mean, u = 43.1 hours
Standard deviation, s = 5.91 hours
For a confidence level of 90%, the corresponding z value is 1.645. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
43.1 ± 1.645 × 5.91/√41
= 43.1 ± 1.645 × 0.923
= 43.1 ± 1.52
The lower end of the confidence interval is 43.1 - 1.52 =41.58
The upper end of the confidence interval is 43.1 + 1.52 =44.62
Therefore, with 90% confidence interval, the mean amount of time that teens spend online each week is between 41.58 and 44.62

The solutions are
1. If A=B implies c = then A ∪ B = B
<span>2. If B is inside A </span><span>e = then A ∩ B = B
</span>3. A ∪ Ø implies d = A
4. A ∩ Ø imiplies <span>a = Ø
</span>5. B ∪ Ø implies b = B
