If A denotes some event, what does Ā denote?

If P(A) = 0.992, what is the value of P(Ā)?

Answer :

A denotes some event , Ā denotes the complement of A that is Ā contains all the events that does not occur in A.

Given: P(A) = 0.992

We know total probability =1

P(A) + P(Ā)= 1

P(Ā)= 1 - P(A)

P(Ā)= 1 - 0.992 = 0.008

P(Ā) = 0.008

9*15=135

15*4.8=72

9*4.8=43.2

135+72+43.2= 250.2ft (Surface Area)

9*15*4.8=648ft (Volume)

Answer:

As shown in the attached figure we have

$tan(\alpha )=\frac{282}{359}\\\\\therefore \alpha =tan^{-1}(\frac{282}{359})\\\alpha =37.95^{o}$

Now we have $\alpha =\lambda$

Thus angle of depression is $37.95^{0}$

16. Which is greater, 4^-2 or<br> 2^-4? How do you know?<br> Those are exponents.

gladu [14]

Answer:

Both are equal to $\frac{1}{16}$

Step-by-step explanation:

If the exponent is negative we can turn it into a fraction and make it positive.

This means the number goes to the denominator and the numerator becomes one. Therefore the following.

$4^{-2} = \frac{1}{4^{2} } =\frac{1}{16}$

$2^{-4} =\frac{1}{2^{4} } = \frac{1}{16}$

Komok [63]

Answer:

$5x - 7 {x}^{2} - {(2x)}^{2} \\ = ( {2}^{2} {x}^{2} ) - 7 {x}^{2} + 5x \\ = 4 {x}^{2} - 7 {x}^{2} + 5x \\ = x(4x - 7x + 5) \\ = x( 5 - 3x) \\ = { \underline{ \underline{ \: \: 5x - 3 {x}^{2} \: \: }}}$
