Rule: (b^m)^n = b^(mn) (Multiply the exponents m and n together.)

Thus, (b^5)^2 = b^(5*2) = b^10 (answer)

A two digit number is to be formed from the digits 0,1,2,3,4 Repetition of the is allowed. find the probability that the number

ra1l [238]

<h2>Answer:</h2>

<u>Sample space</u> = {10, 11, 12, 13, 14, 20, 21, 22, 23, 24, 30, 31, 32, 33, 34, 40, 41, 42, 43, 44}

∴ n(S) = 20 .

[i] <u>Let A be the event that the number so formed is a prime number</u>.

∴ A = {11,13,23,31,41,43}

∴ n(A) = 6

So, P(A) = n(A)/n(S) = 6/20

∴ P(A) = 3/10.

[ii] <u>Let B be the event that the number so formed is a multiple of 4</u>.

∴ B = {12,20,24,32,40,44}

∴ n(B) = 6

So, P(B) = n(B)/n(S) = 6/20

∴ P(B) = 3/10.

[iii] <u>Let C be the event that the number so formed is a multiple of 11</u>.

∴ C = {11,22,33,44}

∴ n(C) = 4

So, P(C) = n(C)/n(S) = 4/20

∴ P(C) = 1/5.

A box contains 3 defective batteries and 7 good ones. You reach in and pull out three

fomenos

Answer:

The expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

Step-by-step explanation:

Given that a box contains 3 defective batteries and 7 good ones, and I reach in and pull out three batteries, to determine what is the expected number of defective batteries, the following calculation must be performed:

3 + 7 = 100

3 = X

10 = 100

3 = X

3 x 100/10 = X

300/10 = X

30 = X

3 x 3/10 = X

0.9 = X

Therefore, the expected number of defective batteries to be pulled out is 0.9, which rounded to the nearest integer gives a total of 1, that is, 1 of the 3 batteries is expected to be defective.

If you can help me in this I would be very Thankful guys

Answer:

OAB = 75

OAB = 45

OMN = 60

Step-by-step explanation:

so there is a rule for corresponding angles are equal to one another

in this question the corresponding angles would be angle OMN and angle OAB

meaning that since OMN is 45 degrees, then OAB would also be 45 degrees

FOR ANGLE ONM

To find angle ONM, we know that the angle of a straight line is equal to 180 degrees.

If part of the straight line is 120 degrees, then the remaining would mean

180-120 = 60 degrees

thus ONM is 60 degrees

Earlier, we found that corresponding angles are equal and ONM and OBA are corresponding angles which means

OBA also equals 60 degrees.

To find angle OMN, the angles in a triangle add up to 180, since we know angles M and angle N, then

180 - 45 - 60 = 75 degrees

Solve 2 ÷ x =5

Volgvan

So to help with the first one
2 / x = 5
multiply the x on both sides
2 = 5x
divide by 5 to isolate the x
2/5 = x

For the second one
We will use the diamond to help us find the common factor
\ 1 /
\ /
\ /
2 / \ 4
/ 3 \
/ \

1) the product
2) and 4) the two numbers
and 3) is sum

10 is the product and -7 is the sum
so what two numbers (factors of 10)
will equal -7 when added

so we have these numbers that will equal the product of +10 and we will need to find the ones that will equal -7 as the sum
10*1, 2*5, -1*-10, -2*-5
if we add the two numbers we will find respectively
11, 7, -11, -7
As you can see that -2 + -5 = +10 and -2+-5= +10
So we have found the two numbers
now before we factor the expression looks like
( x + a) (x + b)
and when factored looks like
x^2 + (a+b)x + (a*b)
Now we can plug in the numbers and solve to see if -2 and -5 are right
(x + -2) (x + -5)
we will factor it
x^2 +-5x + -2x + 10
x^2 + -7x + 10
so a = -2 and b = -5

Hope this helps :)
