406 divided by 140 makes 2.9 multiply that 100 and you arrive at 290%. Hope this helps!
Answer:
I think its a cute angle im not sure
Answer:
The 95% confidence interval would be given by (0.380;0.440)
The 99% confidence interval would be given by (0.370;0.450)
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The confidence interval for the mean is given by the following formula:
If we replace the values obtained we got:
The 95% confidence interval would be given by (0.380;0.440)
And for the 99% confident interval the critical value would be 2.58 and if we replace we got:
The 99% confidence interval would be given by (0.370;0.450)
Answer:
See below ↓↓
Step-by-step explanation:
1.
- 2/3 x 2/3
- Numerator (N) = 2 x 2 = 4
- Denominator (D) = 3 x 3 = 9
- Fraction = N/D = 4/9
- ⇒ 3. four ninths
2.
- Area completed = 4/6 x 2/5
- Numerator (N) = 4 x 2 = 8
- Denominator (D) = 6 x 5 = 30
- Fraction = N/D = 8/30
- ⇒ 4. eight thirtieths
