Answer:

hypotenuse = squareroot of 61 cm. which is approximately 7.81025 cm

Step-by-step explanation:

5 squared + 6 squared = hypotenuse squared

square root of (5 squared + 6 squared)= hypotenuse

7.81

use the formula a^2+b^2=c^2
put number in formula accordingly
5^2+6^2=c^2

solve: 25+36=61

find the square root of 61

answer is 7.81

There are 412 students and 20 teachers taking buses on a trip to a museum. Each bus can seat a maximum of 48. Which inequality g

-BARSIC- [3]

The inequality $\mathrm{b} \geq \frac{\text { total number of travelers }}{\text { capacity of each bus }}$ gives the least number of buses, b, needed for the trip. The least number of buses is 9

Solution:

Given that, There are 412 students and 20 teachers taking buses on a trip to a museum.

Each bus can seat a maximum of 48.

We have to find which inequality gives the least number of buses, b, needed for the trip?

Now, there are 412 students and 20 teachers, so in total there are 412 + 20 = 432 travelers

The number of buses required “b” is given as:

$\text { (b) } \geq \frac{\text { total number of travelers }}{\text { capacity of each bus }}$

$\text { So, number of buses required } \geq \frac{432}{48}$

Number of buses required ≥ 9 buses.

But least number will be 9 from the above inequality.

Hence, the inequality $\mathrm{b} \geq \frac{\text {total number of travelers}}{\text {capacity of each bus}}$ gives least count of busses and least count is 9.

A 99% confidence interval for the mean μ of a population is computed from a random sample and found to be 6 ± 3. We may conclude

valentina_108 [34]

Answer:

A. there is a 99% probability that μ is between 3 and 9.

Step-by-step explanation:

From a random sample, we build a confidence interval, with a confidence level of x%.

The interpretation is that we are x% sure that the interval contains the true mean of the population.

In this problem:

99% confidence interval.

6 ± 3.

So between 6-3 = 3 and 6 + 3 = 9.

So we are 99% sure that the true population mean is between 3 and 9.

So the correct answer is:

A. there is a 99% probability that μ is between 3 and 9.

HELP ASAP!! LOTS OF POINTS!! WILL MARK BRIAN-LIST

KiRa [710]

Answer:

LSA = 532 yds ^2

Step-by-step explanation:

We do not add the triangles in because they are the bases and the bases do not get added in the lateral surface areas.

From left to right

Rectangle 1

A = lw = 9.9 *20 =198

Rectangle 2

A = lw = 6.8 *20 =136

Rectangle 3

A = lw = 9.9 *20 =198

Add them together

198+136+198

532

LSA = 532 yds ^2

(-4^-2) (49^-1/2) Evaluate the expression

Marizza181 [45]

Answer:

-1/112

Step-by-step explanation:

$-4^{-2}=\frac{1}{-4^2}=-\frac{1}{16} \\ \\ 49^{-1/2}=\frac{1}{49^{1/2}}=\frac{1}{7} \\ \\ (-1/16)(1/7)=-1/112$
