Answer:

Step-by-step explanation:

Multiplying bases with exponents means you have to multiply the base and add the exponent. So:

(10⁴)(5²) = 50⁶

(10³)(5³) = 50⁶

Now the equation is (50⁶/50⁶)³

Anything divided by itself will be one, so the number inside the parentheses is 1.

Now the equation is 1³, and 1x1x1 is 1.

If A denotes some event, what does Upper A overbar denote? If P(A)equals0.999, what is the value of P(Upper A overbar)? Wh

meriva

Answer:

<h3>The event $P(\overline{A})$ denotes the complement of event A.</h3><h3>The value of $P(\overline{A})$ is 0.001</h3>

Step-by-step explanation:

Given that A denotes some event .

And also given that P(A)=0.999

<h3>To find the value of $P(\overline{A})$ :</h3>

Here the event $P(\overline{A})$ denotes the complement of event A Therefore $P(\overline{A})$ contains all the events that does not occur in A.

We know that the total probability is 1

So we have that

$P(A)+P(\overline{A})=1$

$P(\overline{A})=1 -P(A)$

$=1-0.999$

$=0.001$

Hence the complement of event A is $P(\overline{A})=0.001$

<h3>Therefore the value is $P(\overline{A})=0.001$ </h3>

Which of the following are solutions to the equation below?

Natasha2012 [34]

Both A and C would be solutions to the equation.

In order to solve for this you must first get the equation equal to 0.

2x^2+5x+8=6 ----> subtract 6 from both sides
2x^2 + 5x + 2 = 0

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.

a = 2 (because it is the coefficient to x^2)
b = 5 (because it is the coefficient to x)
c = 2 (because it is the end number)

Now we can plug these values into the quadratic equation.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

$\frac{-5 +/- \sqrt{5^{2} - 4(2)(2) } }{2(2)}$

$\frac{-5 +/- \sqrt{9} }{4}$

$\frac{-5 +/- 3 }{4}$

$\frac{-5 + 3 }{4}$ or -1/2 for the first answer

$\frac{-5 - 3 }{4}$ or -2 for the second answer

Find the sum of the sequence 36 37 38 39 ... 109=

uysha [10]

It's an arithmetic sequence:

$a_1=36;\ a_2=37;\ a_3=38;\ ...\ ;\ a_{74}=109\\\\S_n=\dfrac{a_1+a_n}{2}\cdot n\\\\a_1=36;\ n=74;\ a_{74}=109\\\\S_{74}=\dfrac{36+109}{2}\cdot74=\dfrac{145}{2}\cdot74=72.5\cdot74=5365$
