Maurice has a paper bag with three hard candies: two blueberries and one green apple. Yvonne and Kate ask if they can each have one. Yvonne closes her eyes and picks a candy from the bag, hoping for a blueberry. What are the chances she will pick a blueberry candy?
Answer:
The chances of Yvonne to get a blue berry candy in the two cases are 1 and 1/2 in case 1 and 2/3 in the case 2.
Step-by-step explanation:
Maurice has a paper bag with three hard candies
2 blueberries and 1 green apple
Yvonne and Kate want 1 candy each
It is not mentioned that ether Kate has taken a candy already before Yvonne or not so we will consider both the cases
Case 1
If Kate has picked a candy before Yvonne
If Kate gets an Apple green candy then the probability or Yvonne to get a Blueberry will be = 2/2 = 1 ( as there will 2 blueberry candy left in the bag)If Kate has taken a Blueberry candy then there will be 1 blueberry and 1 apple green candy in the bag so the probability of Yvonne to get a Blueberry candy will be = 1/2Case 2
If Kate has not taken any candy from the bag before Yvonne
Probability that Yvonne will get a blueberry candy will be = 2/3
Therefore the chances of Yvonne to get a blue berry candy in the two cases are 1 and 1/2 in case 1 and 2/3 in the case 2.

Answer:
x = 4
Well basically 20 divided by 5 is 4. which makes this clearly the answer because the slope is 20/x which is being divided. So when you times 5 x 4 you get 20. It all comes together in a way.
2. Solve:
у = 3х
x = -2y + 70
Answer: (10,30)
Step-by-step explanation:
y = 3x
x = -2y + 70
Solve by using the substitution method. Substitute the value for x into the first equation and solve for y.
y = 3(-2y + 70) Multiply it out
y = -6y + 210 Add 6y to both sides
+6y +6y
7y = 210
y = 30
Since y is equal to 30, input the value for y into the equation and solve for x.
30 = 3x Divide both sides by 3
x = 10

Answer:
Guava has the most, Nelli juice has second most, Mango juice has third most Papaw juice has 4th most, Woodaple has the least
Step-by-step explanation:
Answer:
From smallest portion to biggest
Wood apple juice,
Papaw juice,
Mango juice,
Nelli Juice
Step-by-step explanation:
By looking at this graph we cam tell Guava juice has the most since it has the biggest section.
Now we can tell Wood apple juice isn't a popular option because it has the smallest section
Now to fill in the gaps, Papaw juice has the second least amount, then Nelli has third least amount, and and Guava Juice has the most.

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1500 after 1 day, what is the size of
the colony after 3 days? How long is it until there are 80,000 mosquitoes?
The size of the colony after 3 days is approximately mosquitoes.
Answer:
There are 2,500 misquitos after 3 days and it takes 158 days to reach 80,000 mosquitos.

[tex] \sqrt[3]{( \frac{1}{8} - x)} = - \frac{1}{2} [/tex]
what is the answer?
∛(1/8 - x) = -1/2
Take the 3rd power of both sides and solve:
(∛(1/8 - x))³ = (-1/2)³
1/8 - x = -1/8
2/8 = x
x = 1/4

Element X is a radioactive isotope such that every 20 years, its mass
decreases by half. Given that the initial mass of a sample of Element X is 410
grams, how long would it be until the mass of the sample reached 270 grams,
to the nearest tenth of a year?
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t

In the given figure, ABCD is a trapezium in which AD || BC,
ABC = 90°, AD = 16 cm, AC = 41 cm and BC = 40 cm. Find the
area of the trapezium,
Answer:
252 cm²
Step-by-step explanation:
Find AB:
AB² = 41² - 40²
AB² = 81
AB = √81
AB = 9 cm
Area of the trapezium = ½(a + b) × h
Where,
a = 16 cm
b = 40 cm
h = 9 cm
Area = ½(16 + 40) × 9
Area = ½(56)×9
Area = 252 cm²

A publishing company conducted a survey asking readers whether they use e-readers. Of the 3,000 readers surveyed, 1,954 said they read books on an e-reader. Use this information to complete the statement. Round your answers to the nearest hundredth.
Answer: See explanation
Step-by-step explanation:
You didn't say what you would like to calculate but based on tbe information given in the question, I guess that you want to calculate the percentage of readers who use an e-reader. This will be:
Number of readers surveyed = 3,000
Number of readers reading on e-reader = 1,954
Percentage of e-readers would then be:
= (1954 / 3000) × 100
= 65.13%
