z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%
Answer:
Both angles have a measure of 134degrees, y = 27degrees.
Step-by-step explanation:
As per what is given in the problem:
There are 2 parallel lines, both are intersected by a transversal.
Remember the theorem, when two parallel lines are intersected by a transversal, then the alternate exterior angles are congruent.
The is meanse that:
3y + 53 = 7y - 55
Solve using inverse operations:
3y + 53 = 7y - 55
+55 +55
3y + 108 = 7y
-3y -3y
108 = 4y
/4 /4
27 = y
Now, substitute back in to find the value of the angle:
3y + 53
y = 27
3 ( 27 ) + 53
81 + 53
= 134
Since the angles are alternate exterior, they are congruent, hence both angles have a measure of 134degrees.
Answer:
3/23 miles per hour
Step-by-step explanation:
2 /23 mile
-----------------
2/3 hour
2/ 23 ÷ 2/3
Copy dot flip
2 /23 * 3/2
Rewriting
2/2 * 3/23
3/23 miles per hour
Answer:
33°C
Step-by-step explanation:
The time between 8:20 and 7:50 is 30 minutes. If it drops 1°C per minute you multiply this number by the amount of minutes which would be 30. This becomes 30°C. Then add the 3° it's at now to become 33°C.
