Answer:

B:21.6

Step-by-step explanation:

12²+18²=C

144+324=468

V468=21.6

Answer:

B 21.6

Step-by-step explanation:

You can solve this using the Pythagorean theorem:

h² = l² + w²

h² = 18² + 12²

h² = 324 + 144

h² = 468

h = √468

h ≈ 21.6

Answer:

The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.

Step-by-step explanation:

We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 15 - 1 = 14

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.761

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}} = 1.761\frac{345}{\sqrt{15}} = 157[/tex]

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 6784 - 157 = 6627

The upper end of the interval is the sample mean added to M. So it is 6784 + 157 = 6941

The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.

Answer:

The number of seconds required to complete 7 revolutions is 236.28 s.

Step-by-step explanation:

Given;

speed of the point on the wheel, ω = 32π/9 rad/min

number of revolutions made by the point, θ = 7 rev

The time taken for the point to make 7 revolutions is calculated as follows;

1 rev = 2π rad

[tex]time (t) = \frac{\theta }{\omega} = \theta \ \times \frac{1}{\omega} \\\\t = (7 \ rev \ \times \frac{2 \pi \ rad}{1 \ rev} ) \ \times (\frac{1}{32 \pi/9 \ \frac{rad}{\min} } )\\\\t = (7 \times 2\pi \ \ rad) \times (\frac{9}{32 \pi }\frac{\min}{rad}) \\\\t = 14 \pi \ (rad) \ \times \ \frac{9}{32 \pi}\ (\frac{\min}{rad} )\\\\t = \frac{14 \times 9}{32} \ \min\\\\t = 3.938 \ \min\\\\t = 3.938 \ (\min) \times \frac{60 \ s}{1 \ \min} \\\\t = 236.28 \ s[/tex]

Therefor, the number of seconds required to complete 7 revolutions is 236.28 s.

If you need to round up to the nearest tenth for this question, you'd put 236.3

Answer:

78.125

Step-by-step explanation:

0.32*x = 25

x = 25/0.32 = 78.125

Answer:

78.125

Step-by-step explanation:

Let the number be Y

32% of Y = 25

32/100 x Y = 25

32Y = 25x100

32Y = 2500

divide both sides by 32

Y = 2500/32

Y = 78.125

To find the rate, you must divide the distance traveled by the time it took.

17.5 m is the distance while time it took was 5 seconds.

So,

17.5 ÷ 5 = 3.5 m/s

The rate of the anchor is 3.5 m/s

Note: I did not ignore the negative sign in the distance but rather acknowledged it as a magnitude. This meant that the anchor was dropping down instead of going up.

Answer:

X n Y , X n Y

Step-by-step explanation:

1) Use Associative law:

X n (X n Y) =  (X n X) n Y

Idempotent law:

= X n Y

2) it is in the 'distributed' form, thus we need to reverse the distribution,

akin to 'factorization':

(X n Y) u (X n Y) = (X n (Y u Y))

which can be further simplified using idempotent law:

= X n Y
