D. A rotation 180° about Z'
Step-by-step explanation:
Answer:
1.17*10²
Step-by-step explanation:
Diameter of the sun is about 1.4 × 10⁶ km
1.4*10⁶ km = 1,400,000
Diameter of the planet venus is about 12000 km
12000 km = 1.2 × 10⁴
Ratio of the diameters
Sun : Venus
1.4 × 10⁶ km : 1.2 × 10⁴
1.4 × 10⁶ km / 1.2 × 10⁴
1.4 / 1.2 × 10^6-4
1.166 × 10²
Approximately
1.17 × 10²
Answer:
P=0.147
Step-by-step explanation:
As we know 80% of the trucks have good brakes. That means that probability the 1 randomly selected truck has good brakes is P(good brakes)=0.8 . So the probability that 1 randomly selected truck has bad brakes Q(bad brakes)=1-0.8-0.2
We have to find the probability, that at least 9 trucks from 16 have good brakes, however fewer than 12 trucks from 16 have good brakes. That actually means the the number of trucks with good brakes has to be 9, 10 or 11 trucks from 16.
We have to find the probability of each event (9, 10 or 11 trucks from 16 will pass the inspection) . To find the required probability 3 mentioned probabilitie have to be summarized.
So P(9/16 )= C16 9 * P(good brakes)^9*Q(bad brakes)^7
P(9/16 )= 16!/9!/7!*0.8^9*0.2^7= 11*13*5*16*0.8^9*0.2^7=approx 0.02
P(10/16)=16!/10!/6!*0.8^10*0.2^6=11*13*7*0.8^10*0.2^6=approx 0.007
P(11/16)=16!/11!/5!*0.8^11*0.2^5=13*21*16*0.8^11*0.2^5=approx 0.12
P(9≤x<12)=P(9/16)+P(10/16)+P(11/16)=0.02+0.007+0.12=0.147
Answer:first add 14.6 to both side of the equation and that will give you what is x equal to
