Find the missing the side of the triangle. A. 0 yd B. 30−−√ yd C. 25–√ yd D. 17−−√ yd
Answers
Answer:
Step-by-step explanation:
This a right triangle so we will use the Pythagorian theorem. x is the hypotenus.
■■■■■ Pythagorian theorem ■■■■■
● x^2 = √10^2 + √10^2
● x^2 = 10 + 10
● x^2 = 20
● x = √20 yd
The missing the side of the triangle is x = 2√5 yd
We can use Pythagoras' theorem to identify the missing side x because the triangle is right angled.
We have the Pythagorean theorem.
a² = b² - c²
where a represents the hypotenuse
The hypotenuse of the question is x.
Fill in the blanks with the values from the above formula.
We now have
x² = (√10)² + (√10)²
x² = 10 + 10
x²
Calculate the square root of both sides.
The final solution is as follows:
x = 2√5 yd

2.Calculate the cost of a can of baked beans, a packet of sugar and a packet of biscuits.
3.How much will 8 cans of baked beans,1 packet of sugar and 6 packets of biscuits cost?
Answers
packet of brown sugar = y
packet of biscuit = z
5x + 4y + 2z = 150 - 26 ⇒ 5x + 4y + 2z = 124 is the total cost of all items.
can of baked beans = x = 1/2 of z
packet of sugar = y = z - 3
5(z/2) + 4(z-3) + 2z = 124
5z/2 + 4z - 12 + 2z = 124
5z/2 + 6z = 124 + 12
2(5z/2 + 6z) = 2(136)
5z + 12z = 272
17z = 272
z = 16 cost of a packet of biscuit.
x = 1/2 of z = 16/2 = 8 cost of a can of baked beans
y = z - 3 = 16 - 3 = 13 cost of a packet of sugar
5x + 4y + 2z = 124
5(8) + 4(13) + 2(16) = 124
40 + 52 + 32 = 124
124 = 124
8(8) + 1(13) + 6(16) = 64 + 13 + 96 = 173 total cost on question 3.

Bias
Answers
Answer:
The answer is D, bias. If bias were a factor in an observational study(which it is not), then the study would be inaccurate due to someone's personal views affecting the results. Therefore bias is not a factor in the process of evaluating an observational study.
I don't know who verified the answer of the person why thought the answer was A, but they were incorrect.
So we choose between "Bias" and "Introduction".
I think that the correct answer is "Introduction" -as it doesn't include any new information about the study, and only summarizes previous work.
