Distance traveled in 3 hrs was (speed in mph)(3 hrs)
Then s(3 hrs) + 12 mi = 132 mi.
Therefore, 3s = 120, and s = 120 miles / 3 hrs = 40 mph (answer)
The y-value is the one on the right. Therefore, the y-value of P is 6. Following the rule, the y-value of P' is 6-16= -10.
Step-by-step explanation:
ah, here you go.
come on, now. you know this now ...
again, mutually exclusive attributes in the table (no overlap here) allow us to add the numbers for a total :
4+2+12+10 = 28 students in total.
how many of those 28 fulfill our desired criteria (has a brother) ?
well, it is the sum of the column "has a brother", as it does not matter, if there is also a sister or not.
so, it is 4 + 12 = 16
therefore, the probability to pick a student randomly, who has a brother is
16/28 = 4/7 = 0.571428571...
Answer:
0
Step-by-step explanation:
Given
- 0.4(3x - 2) +
← substitute x = 4 into the expression
= - 0.4(3(4) - 2) + 
= - 0.4(12 - 2) + 
= - 0.4(10) + 
= - 4 + 4 = 0
