The perimeter of a kite is 52 meters. If one side measures 19 meters find the measure of the opposite side.
Setler [38]

For any kite, we have two pairs of congruent adjacent sides. In general, the kite would have sides of x, x, y , y. In this case, x = 19 is known while y is unknown.

The four sides add up to 52, so

x+x+y+y = perimeter

19+19+y+y = 52

38+2y = 52

2y+38-38 = 52-38 .... subtract 38 from both sides

2y = 14

2y/2 = 14/2 ... divide both sides by 2

y = 7

Therefore the opposite side of the 19 meter side is 7 meters

<h3>Answer: B) 7 meters</h3>

Please helppp 15 pointsss What is the y-coordinate of the solution for the system of equations?
Lina20 [59]

y = 3x - 1

x - y = -9


Subs y in second equation.


x - (3x - 1) = -9

x - 3x + 1 = -9

-2x = -9 - 1

-2x = -10

x = -10/-2

x = 5


Subs x


y = 3x - 1

y = 3.5 - 1

y = 15 - 1

y = 14

PLEASE HELP
zhuklara [117]
Beck add like terms so you get
4x^2 -4x-15
lucy factor our negative so you left with -4x^2 +5x -10 +8x^2 -9x -5
simplify 4x^2 -4x -15
therefore both students answers simplify to 4x^2 -4x -15

A die is rolled 23 times and the number of twos that come up is tallied. If this experiment is repeated many times, find the sta
Anon25 [30]

The probability of rolling a 2 is 1/6. If X is a random variable representing the number of 2s that are obtained after rolling a die 23 times, then X follows a binomial distribution with success probability p = 1/6 across n = 23 trials.

The variance of a binomial distribution with parameters p and n is n p (1 - p), so the standard deviation in this case would be

√(23 • 1/6 • 5/6) ≈ 1.8
