Answer:

(x,y) -> (-y,x), second option.

Step-by-step explanation:

Rotation of 90 degrees about the origin:

The rule for a rotation of a point (x,y) 90 degrees about the origin is given by:

(x,y) -> (-y,x)

This is that the question asks, and so, this is the answer, which is the second option.

player A led a baseball league in runs batted in for the 2006 regular season. Player B, who came in second to Player A, had 12 f
Nikitich [7]
Let x be the number of batted runs for player A, then the number of batted runs for player B is x - 12

Given that both <span>players brought home 248 runs during the 2006 regular season, this means that

x + x - 12 = 248
2x = 248 - 12 = 236
x = 236 / 2 = 118.

The United States Postal Service reports 95% of first-class mail within the same city is delivered within two days of the time o
choli [55]

Answer:

Step-by-step explanation:

This is a binomial probability distribution because the outcome is either a randomly selected first-class mail within the same city is delivered within two days of the time of mailing or more days. The probability of success, p is that it is delivered within 2 days. Therefore,

p = 95/100 = 0.95

q(probability of success) = 1 - p = 1 - 0.95 = 0.05

n = number of samples = 6

1)The probability that all six arrive within two days, P(x = 6) would be determined from the binomial probability distribution calculator. Therefore,

P(x = 6) = 0.74

2) P(x = 5) = 0.23

3) mean = np = 6 × 0.95 = 5.7

4) Variance = npq = 6 × 0.95 × 0.05 = 0.285

Standard deviation = √0.285 = 0.53

*Translate into an algebraic expression: How much 50% sugar syrup can you make if you have x grams of sugar?
Irina-Kira [14]

Answer:

w = x/50% = x/50/100

Step-by-step explanation:

We would turn the above question into an algebraic expression using variables.

To make a sugar syrup, we need sugar and water to form the solution.

Amount of sugar = x gram

Let amount of water = w gram

Sugar syrup solution = 50%

Sugar syrup solution = (amount of sugar)/(amount of water) × 100

50% = x/w × 100%

50% = x/w

Making w subject formula

w = x/50%

w = x/50/100
