Answer:

31/20

Step-by-step explanation:

You need to plug in x as y-3.

so instead of 10x+10y=1 it is 10(y-3)+10y=1

Then just simplify the equation to find the value of y

Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2
Lynna [10]

The equivalent expression to the given expression is \mathbf{=-(\dfrac{7}{4}x+5)}

<h3>What is an algebraic expression?</h3>

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2

=\dfrac{1}{2}x -\dfrac{9}{4}x +2 -7

=\dfrac{1}{2}x -\dfrac{9}{4}x -5

=-\dfrac{7}{4}x-5

\mathbf{=-(\dfrac{7}{4}x+5)}

Using conversions between odds and probabilities, we have that:

1. A) 4:21

2. 0.952 probability that a bag of flour passes inspection.

3. C) 1:39

4. 41:59.

5. 14:11

  • A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
  • An odd is given by a:b, in which <u>a is the number of successes and b is the number of failures</u>.

Item 1:

  • Probability of 0.16, thus, for 100 trials, <u>16 successes and 84 failures</u>, and the odd is:

16:84, which, simplifying by 4, is 4:21.

Item 2:

  • Odd of 20:1 means that 20 + 1 = <u>21 trials, there are 20 successes</u>, thus, the probability is:

p = \frac{20}{21} = 0.952

0.952 probability that a bag of flour passes inspection.

Item 3:

  • Probability of 0.025, thus, for 100 trials, <u>2.5 successes and 97.5 failures</u>, and the odd is:

2.5:97.5, which, simplifying by 2.5, is 1:39.

Item 4:

  • 59% probability that he will take the longest trail, thus 100 - 59 = 41% probability of him <u>not tanking the longest trail</u>, thus, the odds against him taking the longest trail is 41:59.

Item 5:

  • Probability of 0.56, thus, for 100 trials, <u>56 successes and 44 failures</u>, and the odd is:

56:44, which, simplifying by 4, is 14:11.

Each number after the first is derived in the same way from the previous number. What is the number that logically follows 63?
alexdok [17]

The number that logically follows 63 would be 31.

arithmetic progression

We arrive at this logical conclusion by finding the common difference between the second number (94) and (63) in the arithmetic series.

That is, 94 - 63 = 31

Adding this common difference (31) in reversal would lead to the same logical order: 31+63 = 94. Hence, 31 is the number that logically follows 63. Remember, once we know the common difference in the numeric series, it allows us what number should logically follow.
