Your teacher is giving out fruit for lunch. A paper bag contains 4 apples, 6 pears, and 8 oranges. What is the probability you will pick an orange at random? What is the complement to this event? What is the probability of the complement? Which fruit is more likely to be chosen?
Answer:
What is the probability you will pick an orange at random? 4/9
What is the complement to this event? Pulling either an apple or a pear from the bag
What is the probability of the complement? 5/9
Which fruit is more likely to be chosen? Orange
The probability you will pick an orange at random is 4/9, the complement event is taking an apple or a pear out of the bag, and the probability of complement event is 5/9, and the fruit is orange.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have the total number of fruits = 4+6+8 = 18
The probability you will pick an orange at random = 8/18 = 4/9
Complement of the above event: Taking an apple or a pear out of the bag
The probability of the complement
P = 1 - 4/9 = 5/9
As the probability of the choosing an orange is greater than others, so the orange is the fruit which is more likely to be chosen.
Thus, the probability you will pick an orange at random is 4/9, the complement event is taking an apple or a pear out of the bag, and the probability of complement event is 5/9, and the fruit is orange.

Answer: V = 1649.34
Step-by-step explanation:
The formula for solving the volume of a right cylinder is V = pi r^2h where r = radius and h = height.
We know that radius is half the diameter so r = 5 because the diameter is 10 ft. We already know height = 21 so our equation looks like pi x 5^2 x 21
5^2 = 5 x 5= 25
so pi x 25 x 21 = 1649.34
Answer:
V ≈ 1649.34 ft³
Step-by-step explanation:
Volume of a Cylinder: V = πr²h
Diameter = 2 · radius
Step 1: Define
d = 10 ft
h = 21 ft
Step 2: Substitute and Evaluate
10 = 2r
r = 5
V = π(5)²(21)
V = π(25)(21)
V = 525π
V ≈ 1649.34 ft³

In a class of 31 students, there are 17 females. What is the ratio of males to females in the class?
Answer:
14
Step-by-step explanation:
The ratio of males to females in the class is 14:17.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Number of students= 31
Number of females= 17
Number of males = 31- 17
= 14
So, ratio of males to females in the class
= 14/ 17
= 14: 17
Hence, the ratio of males to females in the class is 14:17.

Write the vertex form of a parabola that has the same shape as the parent graph of f(x) = x^2 but with the vertex point
at (5, 4).
Answer:
f(x) = (x - 5)² + 4Step-by-step explanation:
Parent graph: f(x) = ax² and vertex (h, k) means the vertex form of a parabola that has the same shape: f(x) = a(x - h)² + k
f(x) = x² ⇒ a = 1
vertex: (5, 4) ⇒ h = 5, k = 4
Vertex form of a parabola that has the same shape as the parent graph of f(x) = x^2 and the vertex (5, 4):
f(x) = (x - 5)² + 4
A store has 2 separate displays of color markers. There are 16 sets of color markers in each display. There are 14 markers in each set. What is the total number of markers on display?
Answer:
The total number of markers on display is 448 markers.
Step-by-step explanation:
Given;
number of sets of color markers in each display, = 16
number of markers in each set, = 14
The number of markers in a single display = 16 x 14 = 224 markers
The total number of markers on the 2 display is = 2 x 224 markers = 448 markers.
Therefore, the total number of markers on display is 448 markers.

Answer: x^(3/8)
====================================================
Explanation:
The rule we use is
[tex]\Large \sqrt[n]{x^m} = x^{m/n}[/tex]
This allows us to go from root form to exponent form, and vice versa.
The index of the root is the denominator of the fractional exponent.
In this case, m = 3 and n = 8, so,
[tex]\Large \sqrt[8]{x^3} = x^{3/8}[/tex]
Answer:
x^(3/8)
Step-by-step explanation:
It's in your genes: Human genetic material (DNA) is made up of sequences of the molecules adenosine (A), guanine (G), cytosine (C), and thymine (T), which are called bases. A codon is a sequence of three bases. Replications are allowed, so AAA, CGC, and so forth are codons. Codons are important because each codon causes a different protein to be created (a) how many different codons (b) how many different codons are there in which all three bases are different (c) the bases A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which the first base is a purine and the second and third are pyrimidines?
Answer:
a. 64
b. 24
c. 16
d. 6/16
e. 1/8
Explanation:
a. How many different codones are there?
Answer: there are 64 different codons
b. How many different codons are there in which all three bases are different?
Answer:there are 24 different codons in which all three bases are different
c. The base A and G are called purines, while C and T are called pyrimidines. How many different codons are there in which first base is purines and second base is pyrimidines
Answer: there are 16 different codons where the which first base is purines and second base is pyrimidines
d. What is the probability that all three bases are different?
Answer: probability of all three bases being different is
Number of codons with three different bases / total number of codons
= 24/64 = 6/16
e. What is the probability that first base is purines and second and third base is pyrimidines?
Answer: prob is number of codons with first base being purine and second and third base being pyrimidines / total number of codons

Ms. Smith bought 30 boxes of pencils in the beginning of the year. Each box cost $2.15 including tax. 6/15 of the boxes she bought have been used. How much money did she spend on the remaining boxes?
Answer:
$45
Step-by-step explanation:
In order to begin solving this problem, we need to first calculate the number of remaining (unused) boxes. We do this by multiplying the total number of boxes by the percentage of boxes remaining. Since Mr. Smith used 6/15 of the boxes we know that there are 9/15 remaining (15-6 = 9). If we divide 9 by 15 we get 0.60 which is the percentage of remaining boxes in decimal form. Now we simply multiply this by the total initial number of boxes
30 * 0.60 = 18 remaining boxes
Now that we know how many unused boxes there are, we simply multiply this number by the cost of each box.
18 * $2.15 = $45
