Answers
Using it's concept, the probabilities are given as follows:
a) 0.5455 = 54.55%.
b) 0.5909 = 59.09%.
c) 0.4615 = 46.15%.
d) 0.5556 = 55.56%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
Item a:
Out of 110 people, 60 prefer sprite, hence the probability is:
p = 60/110 = 0.5455 = 54.55%.
Item b:
Out of 110 people, 65 are between 21 and 40, hence the probability is:
p = 65/110 = 0.5909 = 59.09%.
Item c:
65 people are between 21 and 40, and of those, 30 drink lemonade, hence the probability is:
p = 30/65 = 0.4615 = 46.15%.
Item d:
45 people are under 21 years of age, and of those, 25 drink sprite, hence the probability is:
p = 25/45 = 0.5556 = 55.56%.

The total cost of flooring a room at Rs .9.50 per square meter is Rs 760, If the length of the room is 10 m, find its breadth.
Answers
Answer:
8 metre
Step-by-step explanation:
cost of flooring per square metre = Rs .9.50
total cost of flooring= Rs760
Area of room= 760/9.50
= 80 m^2
Area of the given room= Lenght × Breadth
length of the room is = 10 m
80= 10 × Breadth
Breadth= 80/10= 8 m
Hence, breadth of the room is 8metre

Answers

Celia used celery, carrots, and tomatoes in a recipe. Use the clues to find the amount of each ingredient she used. CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup. CLUE 2: There is less celery than tomatoes. CLUE 3: There is less tomatoes than carrots.
Answers
Answer:
Celery = 3/8 cups
Tomatoes = 2/5 cups
Carrot = 5/4 cups
Step-by-step explanation:
CLUE 1: The amounts were 2/5 cup, 3/4 cup, and 5/8 cup
CLUE 2: There is less celery than tomatoes.
CLUE 3: There is less tomatoes than carrots
From clue 2 and 3:
Tomato > Celery ; Carrots > tomatoes
From least to highest :
Celery < Tomatoes < Carrot
Arranging clue 1 in ascending order :
2/5 = 0.4
3/8 = 0.375
5/4 = 1. 25
Hence,
3/8 < 2/5 < 5/4
Celery = 3/8 cups
Tomatoes = 2/5 cups
Carrot = 5/4 cups

Answers
Answer:
122.09 (the answer may change depending on how many decimals you need if you need more or less just follow the steps using however many decimals)
Step-by-step explanation:
to get the other triangle side do 18-11= 7
then use the Pythagoras theorem to solve for the other side so 7^2+b^2=11^2
49+b^2= 121
121-49= b^2
72=b^2
b= 8.48(simplified)
then use that side to get the area of the rectangle:
8.42×11=92.62
then get area of the triangle:
1/2(8.42×7)=29.47
add the 2 areas to get total area:
92.62+29.47=122.09

Twice the complement of an angle is 24 degrees less than its supplement. What is the measure of the angle?
Answers
Answer:
2(90-x)=180-x-24
solve this
180-2x=156-x
solve the rest on your own
Hope it helps!
The measure of the angle will be 24 degree.
What is Complementary angle?
When sum of two angles are 90 degrees then the two angles are called Complementary angles.
Given that;
The expression is,
''Twice the complement of an angle is 24 degrees less than its supplement.''
Now,
Let measure of an angle = x degree
The complement of an angle x = (90 - x) degree
The supplement of an angle x = (180 - x) degree
Then, By the given condition we can formulate;
2 ( 90 - x) = (180 - x) - 24
180 - 2x = 180 - x - 24
180 - 2x = 156 - x
Subtract 180 both sides;
180 - 2x - 180 = 156 - x - 180
- 2x = - x - 24
Take negative sign common,
2x = x + 24
Subtract x both side,
2x - x = 24
x = 24
Thus, The measure of the angle will be 24 degree.
