Answer :
1. Choose A, 2. Choose B, 3. Choose C, 4. Choose A, 5. Choose A
Explanation :
1. 91, 85, __, 73, __, 61
We see that each number has a difference of 6. Therefore, 91 minus 6 is 85. 85 minus 6 is 79, 79 minus 6 is 73, 73 minus 6 is 67, 67 minus 6 is 61.
Therefore, the missing numbers are :
91, 85, 79, 73, 67, 61
So, choose A.
2. 38, 46, __, 62, __, 78
We see that each number has a difference of 8. So, 38 plus 8 is 46, 46 plus 8 is 54, 54 plus 8 is 62, 62 plus 8 is 70, 70 plus 8 is 78.
Therefore, the missing numbers are :
38, 46, 54, 62, 70, 78
So, choose B
3. 34, 39, __, __, 54, 59
We see that each number has a difference of 5. So, 34 plus 5 is 39, 39 plus 5 is 44, 44 plus 5 is 49, 49 plus 5 is 54, 54 plus 5 is 59.
Therefore, the missing numbers are :
34, 39, 44, 49, 54, 59
So, choose C
4. 15, 30, __, 60, __.
We see that each number has a difference of 15. So, 15 plus 15 is 30, 30 plus 15 is 45, 45 plus 15 is 60, 60 plus 15 is 75.
Therefore, the missing numbers are :
15, 30, 45, 60, 75.
So, choose A.
5. 829 x __ = 829
∴ 829 x 1 = 829
So, choose A.

Step-by-step explanation:

Step-by-step explanation:
The students are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question, we have that:
13 + 7 = 20 teachers, which means that N = 20.
7 history teachers means that k = 7.
Two teachers for each student, which means that n = 2.
What is the approximate probability that a random student on the trip will be assigned to a group led by two history teachers?
This is P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,20,2,7) = \frac{C_{7,2}*C_{13,0}}{C_{20,0}} = 0.1105[/tex]
So close to 11.1%, and the correct answer is given by option A.

Answer:
To use a unit cube, you have to multiply the length and the width just like finding the area of a 2D shape. You will then take your "area" and multiply that by the height of the object.
Step-by-step explanation:
Example, if I have a rectangular prism that is 10 inches long, 4 inches wide, and 6 inches tall, I can multiply 10 and 4 to get 40. I will then take the 6 inches, and multiply it to 40. 40x6=240. The volume of my prism is 240.
I would also like to point out that you can multiply the factors in any order because of the commutative property
A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 17 cm
long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the
bookmark? Use 3.14 for it.
The area of the bookmark is
cm?
Answers
Answer:
80.56
Step-by-step explanation:
To find the rectangle area you just multiply its length by its width:
17 * 4 = 68
You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula: [tex]\pi*r^2[/tex]
Since the radius (r) is 2 and [tex]\pi[/tex] is 3.14, you have the following equation:
A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 (A is Area)
Sum the rectangle's area with the circle's area:
12.56 + 68 = 80.56

Answers
Answer:
y = -27 when x = 9 and z = -3
Step-by-step explanation:
y = kxz is the joint variation where k is a constant
Substitute the knowns in to find k
-50 = k( -10)(5)
-50 = -50k
k = 1
y = xz
Now find y
y = 9*-3

Explanation for Number 7.
The exterior angle is always equl to the sum of the two opposite interior angles.
The two opposite interior angles: 62 and (7x + 14)
The exterior angle: (15x - 4)
So you would set it up like _____ = ______ to solve for x
62 + (7x +14) = 15x - 4
62 + 7x + 14 = 15x - 4
Then move the terms
76 + 7x = 15x - 4
Collect the like terms and Calculate
7x - 15x = -4 - 76

factorise 4a-6ab-18ac
Answers
Answer:
Step-by-step explanation:
4a-6ab-18ac
=2a(2-3b-9c)
The required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).
What is factorisation?In mathematics, factorisation or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.
The given equation is,
4a-6ab-18ac
So factorising each term we have,
4a = 2*2*a
6ab = 2*3*a*b
18ac = 2*3*3*a*c
Thus the equation becomes,
4a-6ab-18ac = 2*2*a - 2*3*a*b - 2*3*3*a*c
taking 2*a common we get,
4a-6ab-18ac = 2a(2 - 3b - 3*3*c)
or, 4a-6ab-18ac = 2a(2 - 3b - 9c)
which is the the required factorisation of the equation.
Thus, the required factorisation of the given equation is 4a-6ab-18ac = 2a(2 - 3b - 9c).

You are looking to save money to start a business. You currently have $500 saved up. We JustWantUrMoney Bank offers a savings account with 12%
interest, compounded annually. How much money would you have after 10 years? Round to the nearest cent, if necessary.
Answers
Answer:
You would have $1552.9 after 10 years.
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
You currently have $500 saved up.
This means that [tex]P = 500[/tex]
12% interest, compounded annually.
This means that [tex]r = 0.12, n = 1[/tex].
How much money would you have after 10 years?
This is A(10). So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]A(10) = 500(1 + \frac{0.12}{1})^{10}[/tex]
[tex]A(10) = 1552.9[/tex]
You would have $1552.9 after 10 years.
