Answer:
C. Angles X and Z are supplementary
Step-by-step explanation:
A: This is true because in Angle Y, a right angle is shown. A right angle is worth 90°.
B: This is true because X, Y, and Z are supplementary (add to 180), and given that Angle Y is 90 degrees, 180 - 90. Thus, they're complementary.
C: This is false and the correct answer choice because Angle Y exists too. Angle X and Z, added together, would make 90 degrees, not 180.
D: This is true because Angles Y and Z are right next to each other, and that's what adjacent means.
Therefore, the answer is C.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Your answer would be approximately 30 women because:
40/6=6.6 (repeating)
since there cant be .6 of a woman, we will get rid of .6
now we have 40/6=6
finally:
6*5= 30
i hope this helps you! :)
Answer:
D. It is the method that is most likely to give a true representative sample.
Step-by-step explanation:
The advantage of selecting a random sample is that is without bias, so being a true representative sample.
For example, if you want to estimate the proportion of the population of a certain city that is going to vote for a candidate in the elections, you must select at a place where different people passes, not one uniform place like a school, just a simple example.
So the correct answer is:
D. It is the method that is most likely to give a true representative sample.
Answer:
-9(7+3)x
Step-by-step explanation:
7+3=10×9=90 so that'll be 90x
A cyclist traveling at 26 mph is followed 6 hours later by a car traveling at 78 mph.
Let x be the time taken by the cyclist
Speed of the cyclist = 26 mph
WE know distance = speed * time
so distance traveled by cyclist = 26*x
car started 6 hours later
(x-6) is the time taken by the car
Speed of the car = 78 mph
distance traveled by car = 78(x-6)
when the car overtakes the cyclist then the distance becomes same
so 26x= 78(x-6)
solve for x
26 x = 78x - 468
Subtract 78x on both sides
-52x = -468
Divide both sides b y 52
so x= 9
Time taken by the cyclist = 9 hours
car started 6 hours later
So time taken by the car = 9-6 = 3 hours
it will take 3 hours for the car to overtake the cyclist
