Answer:
y =36
z= 54
Step-by-step explanation:
The angles 3y and 2y form a straight line, so they add to 180 degrees.
3y+2y =180
5y = 180
Divide each side by 5
5y/5= 180/5
y =36
The angles z, y, from a 90 degree angle
z+y =90
z+36 = 90
Subtract 36 from each side
z+36-36 = 90-36
z = 54
9 goes into 430 47.777.... times repeateded. so 47.78
First we can figure out an hourly rate at which cars are washed. To do so, we need to divide 5 cars by 3 hours.
Then we need to multiply 7.5 hours by the rate. This will tell us how many cars are washed in 7.5 hours.
= 12.5 cars
9 and 3/8 is 75/8 as a mixed #.
Answer:
- P(Yellow)=0.25
- P(Not Red)=0.65
Step-by-step explanation:
P(Red)=0.35
P(Green)=0.4
(a)Since there are three colours inside the bag
P(Red)+P(Green)+P(Yellow)=1
0.35+0.4+P(Yellow)=1
P(Yellow)=1-(0.35+0.4)
P(Yellow)=0.25
(b) In probability, the sum of an event and its complement is 1.
Therefore:
P(Red)+P(Not Red)=1
0.35+P(Not Red)=1
P(Not Red)=1-0.35
P(Not Red)=0.65
