Question 4: 11 p The sum of the digits of a two-digit number is 14. When the digits are reversed the new number is 36 less than
svetoff [14.1K]

Answer:

  95

Step-by-step explanation:

Let x represent the ones digit. The tens digit will be higher, because reversing the digits results in a lower number. Its value is (14 -x). The given relation is ...

  (10(14-x) +x) -(10x +(14 -x)) = 36 . . . . reversing the digits gives 36 less

  140 -9x -9x -14 = 36 . . . . eliminate parentheses

  90 = 18x . . . . . . . . add 18x-36

  5 = x . . . . . . ones digit

  14-5 = 9 . . . tens digit

The original number is 95.

__

<em>Check</em>

  95 -59 = 36

_____

<em>Additional comment</em>

The difference in value when the digits of a 2-digit number are reversed is always 9 times the difference in the digits. This means the difference in the digits is 36/9 = 4. Since the sum of digits is 14, the two digits are (14+4)/2 = 9 and (14-4)/2 = 5. 95 is the number of interest.

The solutions to a "sum and difference" problem are half the sum and half the difference of the given sum and difference. That is how we know the larger digit is (1/2)(14 + 4), for example.

We worked this "the hard way" using the above equation. It can actually be worked in your head if you're familiar with these generic solutions.

A certain circuit board consists of two resistors, green and red. The circuit board manufacturer has two huge bins filled with t
Lesechka [4]

Answer:

(a) 0.675

(b) 0.3

Step-by-step explanation:

P(R) = 90\% = 0.9 (Probability of functional red)

P(\sim R) = 90\% = 1 - 0.9 = 0.1 (Probability of non-functional red)

P(G) = 75\% = 0.75 (Probability of functional green)

P(\sim G) = 1 - P(G) = 1 - 0.75 = 0.25 (Probability of non-functional green)

(a) The probability the board is functional is the probability that the red and the green resistors are functional.

P(\text{board is functional}) = P(R\cap G) = P(R) \times P(G) = 0.9\times0.75 = 0.675

(b) The probability that exactly one of the resistors chosen is functional is the probability that either red is functional and green is not or green is functional and red is not.

P(\text{exactly one is functional}) = P((R\cap \sim G) \cup (G\cap \sim R))

P(\text{exactly one is functional}) = P(R\cap \sim G) + P(G\cap \sim R) = (P(R) \times P(\sim G)) + (P(G) \times P(\sim R))

P(\text{exactly one is functional}) = (0.9 \times 0.25) + (0.75 \times 0.1) = 0.225 + 0.075 = 0.3

kirill [66]

Answer:

Tax: $3.36

Total Cost: 51.36

Step-by-step explanation:

First, we need to figure out the tax, which is 7% of 48. Meaning that the tax is $3.36. Then, we add that to the cost of the sweater which is $48, which means that the total cost is 3.36 + 48 = $51.36
