Answer:

6 18/25 = 6.72

Step-by-step explanation:

The right triangles are similar, so corresponding sides are proportional.

∆XZY ~ ∆ZWY

XZ/XY = ZW/ZY

24/25 = x/7

x = 7(24/25) = 168/25

x = 6 18/25 = 6.72

At a particular garage, 60% of the customers require an oil change, 20% require tire rotation, and 75% of customers require at l

Answer:

a. 5%

b. 55%

c. 70%

Step-by-step explanation:

a. The probability of customer wanting both services (P(O&T)) is:

$P(O)+P(T)+P(O\&T) = 0.75\\P(O)+P(O\&T) =0.60\\P(T)+P(O\&T) = 0.20\\P(O)+P(T)+P(O\&T) -[P(O)+P(T)+2P(O\&T)]=0.75 -(0.60-0.20)\\P(O\&T)=0.05=5\%$

The probability is 5%

b. The probability that the customer will need an oil change, but not a tire rotation (P(O)) is :

$P(O)+P(O\&T) = 0.60\\P(O\&T) = 0.05\\P(O) =0.60-0.05 = 0.55 = 55\%$

The probability is 55%

c. The probability that the customer will want exactly one of these two services (P(O)+P(T)) is:

$P(O)+P(T)+P(O\&T) = 0.75\\P(O\&T) = 0.05\\P(O)+P(T) =0.75-0.05 = 0.70 = 70\%$

The probability is 70%

Trig please help

enot [183]

Answer:

One

Step-by-step explanation:

9/sin(34) = 6/sinC

sinC = 0.372795269

C = 21.9, 158.1

Since 158.1 + 34 = 192.1 > 180

It will not form a triangle

So,

Only one triangle with angle 21.9° at C

Answer:

Y+5=2(x+1) if (5,10)

10+5=2(5+1)

15=2(6)

15=12

Y+5=2(x+1) if (-1,-5)

-5+5=2(-1+1)

0=2(0)

0=0
