Find the value of x and y.

Mrrafil [7]

Answer:

Step-by-step explanation:

CD and AB are parallel; DB transverse

∠D + ∠B = 180 {co interior angles}

112 + 27 + y = 180

139 + y = 180

y = 180 - 139

y = 41

In ΔABC,

49 + x + y = 180 ( sum of all angles of triangle}

49 + x + 41 = 180

90 + x = 180

x = 180 - 90

x = 90

All Seasons Plumbing has two service trucks that frequently need repair. If the probability the first truck is available is 0.75

oksano4ka [1.4K]

Answer: There is a probability of 0.05 that there is neither truck is available.

Step-by-step explanation:

Since we have given that

Probability that the first truck is available = 0.75

Probability that the second truck is available = 0.50

Probability that both trucks are available = 0.30

So, probability that either first truck or second truck is available is given by

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\P(A\cup B)=0.75+0.50-0.30\\\\P(A\cup B)=0.95$

We need to find the probability that neither truck is available.

so, P(A∪B)'=1-P(A∪B)

$P(A\cup B)'=1-0.95=0.05$

Hence, there is a probability of 0.05 that there is neither truck is available.

47. Which of the following represents 0.2% of 1/5?

erica [24]

First think of what 0.2% is as a fraction,

$0.2\%=\frac{0.2}{100}=\frac{2\cdot10^{-1}}{10^2}=\frac{2}{10^3}=\frac{2}{1000}$

Now multiply the fraction by a fifth,

$\frac{2}{1000}\cdot\frac{1}{5}=\frac{2}{5000}$

Which then simplifies to,

$\frac{2}{5000}=\boxed{\frac{1}{2500}}$

Hope this helps :)
