How many even positive integers less than 300 can be written using the number 2 4 5 and 8?

Mathematics
1 answer:
AfilCa [17]2 years ago
4 0

Answer:

18

Step-by-step explanation:

Let us first tackle 2-digit numbers.

They are 24, 25, 28, 42, 45, 48, 52, 54, 58, 82, 84, and 85. That makes 12 2-digit numbers.

Now for the 3-digit numbers:

245, 248, 254, 258, 284, and 285. That makes 6 3-digit numbers.

Therefore, there are 12 + 6 = 18 numbers under 300 that can be made using these numbers.

LMNO~QRST find the value of x.
adelina 88 [10]
Since both trapezoids are similar, so LMNO is a scaled version of QRST by some magnitude
so we can easily use the concept of ratios to find x
in other words: x÷2=6÷5
so x=6×2÷5=12/5=2.4
x=2.4

The following table shows the length and width of two rectangles:
faltersainse [42]
The perimeter of these can be found by adding length and width and then multiplying by two. 

Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2 
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.

Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6

And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8

So it would be C.

The probability that a 38-year-old white male will live another year is .99813. What premium would an insurance company charge t
alukav5142 [94]

Answer:

The insurance company should charge $1,873.5.

Step-by-step explanation:

Expected earnings:

1 - 0.99813 = 0.00187 probability of the company losing $1 million(if the client dies).

0.99813 probability of the company earning x(price of the insurance).

What premium would an insurance company charge to break even on a one-year $1 million term life insurance policy?

Break even means that the earnings are 0, so:

0.99813x - 0.00187(1000000) = 0

0.99813x = 0.00187(1000000)

x = \frac{0.00187(1000000)}{0.99813}

x = 1873.5

The insurance company should charge $1,873.5.
