Answer: the answer is B, or P(B|C)=9/24=0.38

Step-by-step explanation:

If you look at the table, you can see that 9 is where BC is. So, 9 is the numerator. The denominator is 24 because that is the total number.

Also, I got this answer correct on Edge

Answer: P(B|C)=\dfrac{9}{24}=0.38

Step-by-step explanation:

The formula for conditional probability :-

P(M|N)=\dfrac{P(M\cap N)}{P(N)}

From the given table it can be seen that ,

Total = 70

n(C)=24

Then , the probability of having B:-

\text{P(C)}=\dfrac{\text{n(C)}}{\text{Total}}\\\\=\dfrac{24}{70}

Also, n(B\cap C)=9

Then , the probability of having the intersection of B and C :-

P(B\cap C)=\dfrac{n(B\cap C)}{\text{Total}}\\\\=\dfrac{9}{70}

Then , by the formula of conditional probability , we have :-

P(B|C)=\dfrac{P(B\cap C)}{P(C)}\\\\=\dfrac{\dfrac{9}{70}}{\dfrac{24}{70}}\\\\=\dfrac{9}{24}=\dfrac{3}{8}=0.375\approx0.38

Answer:

7over9 or -7over9

Step-by-step explanation:

81x power 2 - 8 = 41

(left side) (right side)

first we let the 8 from left side go to the right side,so it will be +8:

81x power 2 = 41+ 8

=49

so now we let the 81 from left side go to right side, so it will be ÷81:

x power 2= 49 over 81

and now we let the power 2 (square) go to the other side so it will become square root:

x = + - √49 over 81

at the end, you will get 2 answers which is 7 over 9 and - 7 over 9

The edge length of a cube is 17 cm. Identify the length of its diagonal. Round to the nearest tenth, if necessary. HELP PLEASE!!
lara31 [8.8K]

Answer:

29.4 cm

Step-by-step explanation:

The length of the space diagonal can be found to be the root of the squares of the three orthogonal edge lengths. For a cube, those edge lengths are all the same, so the diagonal length is ...

d = √(17^2 + 17^2 +17^2) = 17√3 ≈ 29.4 . . . . cm

_____

Consider a rectangular prism with edge lengths a, b, c. Then the face diagonal of the face perpendicular to edge "a" has length ...

(face diagonal)^2 = (b^2 +c^2)

and the space diagonal has length ...

(space diagonal)^2 = a^2 + (face diagonal)^2 = a^2 +b^2 +c^2

So, the length of the space diagonal is ...

space diagonal = √(a^2 +b^2 +c^2)

when the prism is a cube, these are all the same (a=b=c). This is the formula we used above.

......ssssssssssssssssssssssssssssssssssssshhhhhh
Darina [25.2K]

Hey there! I'm happy to help!

Step 2 is incorrect. She added 4 and 2 first, but you are supposed to multiply and divide first. Then she multiplied 6 and 6, which is 36. Then she divided 36 and 2, which is 18, and then she subtracted 7, giving her 11. Step 2 is what threw the whole thing off.

Here is what Sandy should have done.

STEP 1: 6·4+2÷2-7

STEP 2: 24+1-7

STEP 3: 25-7

STEP 4: 18

I hope that this helps! Have a wonderful day! :D

4-58. Lisa plans to retire on her 61st birthday. On her
mojhsa [17]

Answer:

Lisa invest "$2180.81" in her bank.

Step-by-step explanation:

The given values are:

On Lisa's 62nd birthday,

she withdraw = $10,000

The annuity of $A will remain at 3 percent for 40 years. The retirement pension of $10000 lasts 23 years at rate percentage of 3 but begins 40 years later.

⇒  A\times (\frac{P}{A} ,3 \ percent,40) - 10000 (\frac{P}{A} ,3 \ percent,23)\times \frac{1}{(1.03)40} = 0

⇒  A\times 23.1148 - 10000\times 16.4436\times 0.3066 = 0

⇒  A = 10000\times 16.4436\times \frac{0.3066}{23.1148}

⇒      = 10000\times 16.4436\times 0.0132

⇒      =2180.81 ($)
