24 seconds, 24 minutes, 24 hours, 24 days, 24 weeks, 24 months, 24 years, equals how many days?

Vedmedyk [2.9K]

Answer:

1345.01694448 days

Step-by-step explanation:

24 weeks = 24 x 7 = 168 days

24 months = 24 x 30 x 7 = 168 x 7 = 1176 days

24 seconds = 0.000277778 days

24 minutes = 0.0166667 days

24 hours = 1 day

Total = 1345.01694448 days

When you have two side lengths of 2in and 4.5in What is the other side length?

nika2105 [10]

Answer:

The solution for the other side length is the interval

(2.5,6.5)

Step-by-step explanation:

I will assume that is a triangle

we know that

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Let

x ---> the measure of the third side

Applying the Triangle Inequality Theorem

1) $2+4.5 > x$

$6.5 > x$

Rewrite

$x < 6.5\ in$

2) $2+x> 4.5$

$x> 2.5\ in$

therefore

The solution for the other side length is the interval

(2.5,6.5)

Find (f −1)'(a). f(x) = 4 + x2 + tan(πx/2), −1 < x < 1, a = 4

Vinvika [58]

Answer:

The solution is $(f^{-1})'(a) = \frac{2}{\pi }$

Step-by-step explanation:

From the question we are told that

The function is $f(x) = 4 + x^2 + tan [\frac{ \pi x}{2} ]$ , -1 < x < 1 a = 4

Here we are told find $(f^{-1}) (a)$

Let equate

$f(x) = a$

$4 + x^2 + tan[\frac{\pi x }{2} ] = 4$

$x^2 + tan[\frac{\pi x }{2} ] = 0$

For the equation above to be valid x must be equal to 0

Now when x = 0

$f(0) = 4+0^2 + tan [\frac{ \pi * 0}{2} ]$

=> $f(0) = 4$

=> $0 = f^{-1} (4)$

Differentiating f(x)

$f(x)' = 0 + 2x + sec^2 (\frac{\pi x}{2} )\cdot \frac{\pi}{2}$

Now

since $0 = f^{-1} (4)$

We have

$f(0)' = 0 + \frac{\pi }{2} sec^2 (0)$

$f(0)' = \frac{\pi }{2}$

Now

$(f^{-1})'(a) = \frac{1}{(\frac{\pi}{2} )}$

$(f^{-1})'(a) = \frac{2}{\pi }$

A standard deck of playing cards has 52 cards: 13 spades, 13 clubs, 13 hearts, and 13 diamonds. What is the probability of drawi

Vaselesa [24]

13 spades, 52 cards total

probability of drawing a single spade = 13/52 = 1/4

If we replace that card, then the probability of drawing of drawing a spade is still 1/4 as nothing has changed

Overall, the probability of getting two spades in a row is (1/4)*(1/4) = 1/16

note: the two events are independent because of the replacement happening

---------

The answer as a fraction is 1/16

As a decimal, that would be 0.0625 which converts to 6.25%
