What 4 numbers adding give you a sum of 15

alekssr [168]

Answer: 6 and 9, 7 and 8. 69, 78, 87, 96. So, there are only 4 combinations which would result in 15.

Step-by-step explanation:

Therefore the average sum of three numbers is 45:3=15. The number 15 is called the magic number of the 3x3 square. You can also achieve 15, if you add the middle number 5 three times. The odd numbers 1,3,7, and 9 occur twice in the reductions, the even numbers 2,4,6,8 three times and the number 5 once.

Nonamiya [84]

Answer:

$P(X>7.3) = \int_{5.5}^{7.3} \frac{1}{2} dx = \frac{1}{2} x \Big|_{6.5}^{7.3} = \frac{1}{2} (7.3-6.5)= 0.4$

And then we can find the probability replacing the last result and we got:

$P(X>7.3)= 1- P(X$

Step-by-step explanation:

For this case we have the following density function given:

$f(x) = \frac{1}{2} , 5.5 \leq X \leq 8.5$

And we want to find the following probability:

$P(X>7.3)$

We can find this probability with the complement rule like this:

$P(X>7.3)= 1- P(X$

And we can find the following probability:

$P(X>7.3) = \int_{5.5}^{7.3} \frac{1}{2} dx = \frac{1}{2} x \Big|_{6.5}^{7.3} = \frac{1}{2} (7.3-6.5)= 0.4$

And then we can find the probability replacing the last result and we got:

$P(X>7.3)= 1- P(X$

PLEASE HELP!!!! TIMED EXAM

alexandr402 [8]

Answer:

The correct option is V = one-third (6) (4) (8).

Step-by-step explanation:

The volume of a rectangular pyramid is:

$V=\frac{1}{3}\ l\times b\times h$

Here,

V = volume

l = length

b = base

h = height

The information provided is:

l = 6 inches

b = 4 inches

h = 8 inches.

Compute the equation of the volume of a rectangular pyramid as follows:

$V=\frac{1}{3}\ l\times b\times h$

$=\frac{1}{3}\times 6\times 4\times 8$

Thus, the correct option is V = one-third (6) (4) (8).
