Is 12:30 equivalent to 16:40

2 answers:

5 0

If the difference (i.e. subtraction) between the two values is zero, then the answer is yes, they are the same . . .

16:40 = 16 hours and 40 min
12:30 = 12 hours and 30 min

(16h + 40m) - (12h + 30m)

(16h - 12h) + (40m - 30m)

(4h) + (10m)

4h + 10m

4:10 > 0:00 . . . so the answer is no, they are not the same

They're not the same time. 12:30 ='s 13:30
below is the time that we use and the time thats equal to it in Navy time:
12:30 = 12:30
1:30 = 13:30
2:30 = 14:30
3:30 = 15:30
4:30 = 16:30
5:30 = 17:30
6:30 = 18:30
7:30 = 19:30
8:30 = 20:30
9:30 = 21:30
10:30 = 22:30
11:30 = 23:30

Serjik [45]

Answer:

The 95% confidence interval for the true proportion of mice that will test positive under similar conditions is (0.5291, 0.6429).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence interval $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

Z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

In a collection of experiments under the same conditions, 44 of 75 mice test positive for lymphadenopathy. This means that $n = 75$ and $\pi = \frac{44}{75} = 0.586$ .

Compute a 95% confidence interval for the true proportion of mice that will test positive under similar conditions.

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.586 - 1.96\sqrt{\frac{0.586*0.414}{75}} = 0.5291$

The upper limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.586 + 1.96\sqrt{\frac{0.586*0.414}{75}} = 0.6429$

The 95% confidence interval for the true proportion of mice that will test positive under similar conditions is (0.5291, 0.6429).

Help please. Having some trouble with this question

xeze [42]

Answer:

The answer to your question is 55 ft

Step-by-step explanation:

Data

Person's height = 5 ft

Person's shadow = 10 ft

Tree's height = ?

Tree's shadow = 110 ft

- Use the Thales' theorem to solve this problem

Person's height / Person's shadow = Tree's height / Tree's shadow

- Substitution

5 / 10 = x / 110

-Solve for x

x = 5 (110) / 10

-Simplification

x = 550 / 10

-Result

x = 55 ft

-Conclusion

The tree is 55 ft height

Alison is playing a video game. At the end of each level, the player is given either a bag of gold or a magic wand.

Igoryamba

Outcome Bag of Gold Magic Wand
Relative frequency 0.32 0.68

The relative frequency of getting a bag of gold is .......... reasonably close

.32 is close to 30% so

Alison's claim about the theoretical probability is likely to be 2............true

Further, this means that the theoretical probability of getting a magic wand is most likely 3............1 - 30% = 70%
