ILL BRAINLIEST YOU PLEASE HELP ME

Answer:

y = 32.5

x = 13

Step-by-step explanation:

opposite angles of the parallelogram are equal to each other.

parallelograms form 360° in total

so 60+ 55 = 115 * 2 (because two angles) = 230

360 - 230 = 130 (divide this by two to get one angle of the parallelogram) so 65°

2y = 65 °. and 5x = 65 °

y = 32.5

x = 13

Let X denote the life of a semiconductor laser (in hours) with the following probabilities: P(X ≤ 5000) = 0.05 and P(X > 7000
Anna [14]

Answer:

a) P [ x ≤ 7000] is 0.55

b) P [ x > 5000 ] = 0.95

c)  P [ 5000 < x ≤ 7000 ] = 0,5

Step-by-step explanation:

a)  P [ x > 7000 ]  =  0.45   straightforward    P [ x ≤ 7000] is 0.55

The whole spectrum of probabilities is 1 which in this particular case is divided in two parts having 7000 as a limit, then we subtact 1 - 0.45

b) P [ x ≤ 5000]  = 0.05   again we get P [ x > 5000] taking 1-0.05 to get

P [ x > 5000 ] = 0.95

c) P [ 5000 < x ≤ 7000 ]

Under Normal curve distribution the probability of  x ≤ 7000 includes values   smallers  ( to the left of 5000) so we subtract from 0.55 - 0.05 = 0.50

c) P [ 5000 < x ≤ 7000 ] = 0,5

During a basketball game a player makes 12 of 18 free throws attempted write the ratio as fraction reduced to the lowest term
umka21 [38]
To make this a fraction, let's put \frac{12}{18} . We can divide both top and bottom by 6, leaving us with \frac{2}{3} . This is as far as we can reduce it, making it your answer. I hope this helps!
