To find how high school students feel about hot lunches, Adam walks to the nearest high school and
gives a survey postcard to every twentieth student that enters the building. He asks the students to mail
the postcard in if they choose to participate in the study.
Why might the method used be biased?
Asking every twentieth student does not accurately represent the student population.
It is likely that student opinions in one particular high school do not accurately represent the opinions
of all high school students.
Students that take the time to complete the survey and mail it in probably feel strongly about hot
lunches.

the question is below
Answer: 45
Step-by-step explanation:
90-45 is 45 because there’s a right angle which is 90 degrees and these two angles both stem from that right angle so then the two would be equal to 90. It’s called complementary angles.

Answer:
(a) 58 m²
Step-by-step explanation:
The area of a composite figure is found by dividing it into simpler shapes whose area formulas are known.
DivisionExtending the horizontal line to the left, we find it divides the shape into an upper rectangle with dimensions 2 m wide and 4 m high, and a lower rectangle with dimensions 10 m wide and 5 m high.
Rectangle areaThe area of a rectangle is the product of its dimensions:
A = LW . . . . . where L is the length and W is the width
The upper rectangle has an area of ...
A = (4 m)(2 m) = 8 m²
The lower rectangle has an area of ...
A = (10 m)(5 m) = 50 m²
Total areaThe area of the figure is the sum of the areas of the upper and lower rectangles:
A = (8 m²) +(50 m²) = 58 m²
The area of the figure is 58 square meters.
Additional comment
The area can also be figured by considering an enclosing rectangle 9 m high by 10 m wide, for an area of (9 m)(10 m) = 90 m². From this rectangle, a rectangle 4 m high and 8 m wide is removed from the upper right corner. The removed area is (4 m)(8 m) = 32 m². Then the remaining area is ...
90 m² -32 m² = 58 m² . . . . the area of the figure shown
Caleb throws a ball three times for his dog Leo. For each throw, Leo either
catches the ball or misses it. Identify the sample space (the correct list of
possible outcomes) for the results.
C = catch, M = miss
The notation CMC means Leo caught the first ball, missed the second one,
and caught the third one.
A. {CCCC, CCMM, MMMM}
B. {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
C. {CCC, CMC, MMM}
D. {CC, CM, MC, MM}
Answer:
B {CCC, CCM, CMC, MCC, MMC, MCM, CMM, MMM}
Step-by-step explanation:
Ima try to explain this in the process of elimination:
A isn't right since he only throws the ball 3 times
C isn't right, since he could catch it, miss, then catch again and would still match the criteria stated.
D Isn't right since he threw it 3 times, not twice
that only leaved B to be correct! Hope this helps!

Answer:
I believe the answer is B.
Step-by-step explanation:
The questions says for every 1 hour she reads a book, she reads 0.25 hours with a magazine. Answer B says 2 hours for book, meaning that you wouldn’t have 0.25, you would have 0.5. So for books, you’d go up every 2 hours, and for magazines, you’d continue going up in half’s!

Answer:
132cm
Step-by-step explanation:
Split there firgue into shapes you know
there is a rectangle and a Trapezoid
A = bh
A = 7×4
A = 28cm
Trapezoid
A = 1/2h(b+b)
A = 1/2×8(19+7)
A = 1/2×8(26)
A = 1/2(208)
A = 104cm
Add them together
104 + 28 = 132
Look at figure A and figure B on the coordinate plane below.

Sophia has $6 to spend on lunch during a basketball tournament. The concession stands sell sodas for $0.75 and all of their food items for $1.50. What is the maximum number of food items Sophia can purchase if she buys one drink?
Important info:
- Sophia has $6 to spend on lunch
- Concession stands sell sodas for $0.75
- All of their food items for $1.50
- Pretend she buys one drink
- Find the maximum amount of food she can buy now.
Process:
Subtract 600 and 75 since $6 = 600 cents
600 - 75 = 525
So Sophia has $5 and 25 cents left
Each food item is worth $1.50 which is 150 cents and she currently has $5.25 which is 525 cents
So divided 525 and 150
525 / 150 = 3.5
Unfortunately she can't buy half of a food item so the answer would be 3
Final Answer:
3, Sophia can buy 3 food items after buying 1 drink
