dishwashers. What is the experimental probability that the next appliance Luca sells will be a
dishwasher?
Write your answer as a fraction or whole number.
Answer:
1/2
Step-by-step explanation:
Answer:
0.50
Step-by-step explanation:
6 out of the total 12 appliances sold were dishwashers, so the experimental probability that the next appliance sold will be a dishwasher is 6/12, or 1/2, or 0.50.

Answer:
15.71cm
Step-by-step explanation:
perimeter of a semi circle=1/2(πdiameter)
1/2(3.142×10cm)
1/2(31.42cm)
15.71cm
Answer:
15.71 cm
Step-by-step explanation:
remember the formula for the circumference of a circle but make it half since it's a semi-circle
the perimeter of a circle is diameter x pi
since
the diameter is 10 and pi is 3.142
its 10 x 3.142
and that equals
31.42
that's a FULL circle so half of that
divide it by 2
31.42/2=15.71
so the diamater of the semi-circle is 15.71
hope this helps!

Each figure shows a triangle with one of its angle bisectors.
12) 22 - 38°. Find mZTRS.
Answer:
76 degrees
Step-by-step explanation:
this special line is an angle bisected.
that means it splits the angle at its starting point in 2 halves. as these names indicate, both parts are of equal size (half of the general angle).
we know one part (2) of this split angle : 38 degrees.
the other part (1) had to be equally sized : 38 degrees.
so, the total angle at point R is the sum of both split angles:
TRS = 38+38 = 76 degrees.

No, the point (1,-1) does not the satisfy the inequality 40x-22y<=50.
What is an inequality?
It is a type of equation in which greater than less than or equal to are used instead of only equal to.
How to solve an inequality?
To check whether whether a point satisfies an inequality or not we need to just put it in the inequality. So,
40x-22y<=50
40(1)-22(-1)=40+22=62
62 is not less than and not equal to 50. So it does not satisfies the inequality.

Answer:
Step-by-step explanation:
∠ADC = 90°
∠ADB + ∠BDC = 90
20 + ∠BDC = 90
∠BDC = 90 - 20 = 70
∠BDC = 70°
16) ∠PSR = ∠PSQ +∠QSR
= 60 + 10
= 70
18) ∠PSR = 130
∠PSQ + ∠QSR = 130
90+ ∠QSR = 130
∠QSR = 130 - 90
∠QSR = 40
19)∠ADC = ∠ADB + ∠BDC
= 120 +20
= 140
20) ∠PSR = 125
15. 70° because a right angle is 90° and we have the angle of ADB which is 20°. So 90°-20°=70°.
16. 70° because angle PSQ is 60° and angle QSR is 10°. So 60°+10°=70°.
17. 55° because it says it in the explanation. I assume this is a typo and they meant to ask the measurement of ADC and in that case it would be 130° because angle ADB is 75° and angle BDC is 55°. 75°+55°=130°.
18. 40° because angle PSQ is a right angle which means it's 90°. So 130°-90°=40°.
19. 140° because angle ADB is 120° and angle BDC is 20° so 120°+20°=140°.
20. 125° because again it's in the explanation. But if it's a typo and they meant what is the measurement of PSQ then it is 50° because PSR is 125° and QSR is 75° so 125°-75°=50°.
Hope this helps! :)
ABC is a triangle. AC = 9 cm, BC = 7 cm and angle BAC = 30°
Calculate the size of angle ABC.
9514 1404 393
Answer:
∠B = 40° or 140°
Step-by-step explanation:
The given angle is opposite the shortest of the given sides, so there are two possible solutions.
From the law of sines, ...
B = arcsin(b/a·sin(A)) = arcsin(9/7·sin(30°)) = arcsin(9/14)
Possible values for angle B are ...
B = arcsin(9/14) ≈ 40.0°
B = 180° -arcsin(9/14) ≈ 140.0°

How would you find out how many sixth through eighth grade students are interested in joining a running club?
The question is incomplete. The complete question is :
How would you find out how many sixth through eighth grade students are interested in joining a running club? Explain how to choose a sample that will give you a good representation of a whole population.
Answer :
the sample should be random
Explanation :
We have to find the number of student from 6th through 8th grade students those who wanted to join a running club by choosing a sample of population. So in order to choose a sample which will provide a good representation for the whole population is that the sample must be a [tex]\text{random sample}[/tex] from [tex]\text{entire set of students }[/tex] and it should also include enough students to be reliable. The smaller samples have a more variation that lead to a lesser reliable inference.
