Answer:
area of the semicircle=
diameter²=9²+21.6²
=81+466.56
diameter² =547.56
diameter=√547.56
=23.4
radius of the semicircle=diameter/2=23.4/2
=11.7
area of the semicircle=1/2πr²
=1/2×3.14×11.7²
=214.9173m²
area of the triangle=1/2×9×21.6
=97.2m²
area of the shaded region=214.9173m²-97.2m²
=117.7173m²
round it as possible

Please find x and y!!!!!! URGENT! Bots taken down
Answers
Answer:
x = 11, y = 22
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan60° = [tex]\sqrt{3}[/tex] , then
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{11\sqrt{3} }{x}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by x )
11[tex]\sqrt{3}[/tex] = x × [tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
11 = x
Using Pythagoras' identity in the right triangle
y² = x² + (11[tex]\sqrt{3}[/tex] )² = 11² + 363 = 121 + 363 = 484 ( square root of both sides )
y = [tex]\sqrt{484}[/tex] = 22
What additional information is needed to show that ABC = DEF by SSS?
Answers
Answer:
D.) AC ≈ DF
Step-by-step explanation:
The SSS (Side-Side-Side) congruence postulate states that 2 triangles will be congruent assuming that all 3 of their sides are congruent.
In this case, we know that:
AB ≈ DECB ≈ FESo, that's two pairs of congruent sides. We need one more pair of congruent sides to prove SSS congruence. The last two remaining are sides CA and FD!

Based on data taken from airline fares and distances flown, it is determined that the equation of the least-squares regression line is ŷ = 102.50 + 0.65x, where ŷ is the predicted fare and x is the distance, in miles. One of the flights was 500 miles and its residual was 115.00.
What was the fare for this flight?
102.50
312.50
427.50
542.50
Answers
Answer:
542.50
Step-by-step explanation:
Given:
Least square regression equation :
y = 102.50 + 0.65x + residual
y = predicted fare
x = distance in miles
Intercept = 102.50
Slope = 0.65
Distance in miles, x = 500 miles
y = 102.50 + 0.65(500) + 115
y = 102.50 + 325 + 115
y = 427.5 + 115
y = 542.50
Answer:
Don't know why everyone downvoted the first answer. Maybe you guys suck at clicking. It's correct.
Your answer is 542.50 (D)
102.50 + 65(500) = 427.5
427.5 + 115 = 542.50
You add the residue.

One experiment had 10 players spinning, another experiment had 100 players spinning. Which experiment is more likely to come closer to matching its theoretical probability.
Answers
Answer: Experiment with 100 players sprinting
Step-by-step explanation:
When it comes to experiments using samples to find out the effect of a variable on an entire population by finding out the representative effect on the sample, the larger the size of the sample, the better.
A larger sample comes closer to being the actual size of the population so when this larger sample is experimented upon, the results it gives will be closer to the results that would be gotten if we experimented on the entire population. The 100 player sprinting experiment would therefore come closer to matching its theoretical probability.

Answer:
x = 11
Step-by-step explanation:
Since this is a triangle, all interior angles add up to 180 so:
57 + 73 + 3x + 17 = 180
3x + 147 = 180
3x = 180 - 147
3x = 33
x = 11

Based on the data in the table, what is the probability that the next piece of candy Katherine pulls out of the jar will be blue?
O
A
7/100
B.
7/50
C.
7/43
D.
1/5
Answers
The probability of blue candy from the jar of total candy 50 is 7/50. Thus, option B is correct.
Probability is defined as the chance of occurrence of events. From, the given data the total number candies in the jar is 50.
Thus, the total number of events (sample space, S) = 50
number of possible outcomes from the event n(S) = 50
number of blue candies in the jar(favourable outcomes) = 7
Probability of taking the blue candies from the jar,
P(A) = no. of. favourable outcomes / number of possible outcomes
= 7 / 50
The probability of taking blue candy from the jar = 7/50
Thus, the ideal solution is option B.
