A mathematics test has 15 items. In how many ways can a student answer the exam with 9 correct answers and 6 wrong answers?
a. 15
b. 30
c. 90
d. 5,005
Answer:
Surprisingly the answer is 5,005.
Basically this is asking "in how many ways can you choose 9 things from a set of 15 things".
You will need to use the formula found at the top of this page:
https://www.1728.org/combinat.htm
Filling in the formula in which 'r' = 9 and n = '15'
combinations = n! / (r! * (n-r))!
combinations = 15*14*13*12*11*10 * 9! / (9! * 6!)
combinations = 15*14*13*12*11*10 / 6*5*4*3*2*1
combinations = 14 * 13 * 11 * 10 / 4
= 14 * 13 * 11 * 2.5
= 5,005
answer is "d"

Kevin is hiking on a trail that is 1.8 miles long. So far, he has hiked 80% of the total distance.
How many more miles does Kevin have to hike in order to complete the trail? Complete the explanation on how you found your answer.
Kevin has to hike 0.36 more miles in order to complete the trail.
Part 2 out of 2
Since Kevin has hiked 80% of the trail, he has 100% - 80% or ?%
So, 20% of 1.8 = ? × 1.8 = 0.36.
Answer:
Part 1: 4.5
Part 2: 20%, 0.2
Step-by-step explanation:
1. 1.8 = 80% We need to understand this.
So we can do this then:
2. 1.8/8 = 80%/8
3. 0.225 = 1%
4. 0.225 * 20
5. 4.5
(this is part 1 btw)
Part 2!
20% since 100-80 is 20.
20% -> 0.2

Answer: the top right
Step-by-step explanation:
solve each system of equations by showing the process of substitution.
a) y=-1/4 x and x+2y=4
b) y=-x-2 and 3x+3y=6
c) -8x+2y=4 and y=4x+2
pLS help
Answer:
A. {x,y}={-2,-3}
// Solve equation [2] for the variable x
[2] x = 2y + 4
// Plug this in for variable x in equation [1]
[1] (2y+4) - y = 1
[1] y = -3
// Solve equation [1] for the variable y
[1] y = - 3
// By now we know this much :
x = 2y+4
y = -3
// Use the y value to solve for x
x = 2(-3)+4 = -2
B. [1] 3x=3y-6
[2] y=x+2
Equations Simplified or Rearranged :
[1] 3x - 3y = -6
[2] -x + y = 2
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 2
// Plug this in for variable y in equation [1]
[1] 3x - 3•(x +2) = -6
[1] 0 = 0 => Infinitely many solutions
C.Step by Step Solution

System of Linear Equations entered :
[1] 4x - y = 2
[2] 8x - 2y = 4
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 4x - 2
// Plug this in for variable y in equation [2]
[2] 8x - 2•(4x-2) = 4
[2] 0 = 0 => Infinitely many solutions
Answer:
Step-by-step explanation:
a) y = -1/4x --------------(I)
x + 2y = 4 -----------------(II)
Substitute y = (-1/4)x in equation (I)
[tex]x + 2*\dfrac{-1}{4}x=4\\\\\\x -\dfrac{1}{2}x=4\\\\Multiply \ the \ entire \ equation \ by \ 2 \\\\2x -x = 8\\\\x=8[/tex]
[tex]Substitute \ x = 8 \ in \ equation \ (I)\\\\y=\dfrac{-1}{4}*8\\\\\\y = -2[/tex]
Answer: x = 8 ; y = -2
b) y = -x - 2 --------------(i)
3x + 3y = 6 -----------(ii)
Divide equation (ii) by m
x + y = 2
y = -x + 2 ----(iii)
From (i) and (iii), it shows that these lines have same slope. So, they are parallel lines
Answer: No solution
3) -8x + 2y =4
2y = 8x + 4
Divide the entire equation by 2
y = 4x + 2 -------------(i)
y = 4x + 2 ----------------(ii)
From (i) and (ii), we come to know that these lines coincide.So, they have infinite solutions.

Seventy percent of what number is 35?
Seventy percent of fifty (50) is 35
What is the percentage?The percent or percentage of a number is the division of the number with 100.
From the given information, we are being told that 70% of a number is 35.
Let's assume that the unknown number is: (x)It means that:
70% of x = 35
[tex]\mathbf{(\dfrac{70}{100})x = 35}[/tex]
0.7x = 35
Divide both sides by 0.7
x = 35/0.7
x = 50

use multiplcation to solve the proportion. b/65 = 7/13
Answer:
b = 35
Step-by-step explanation:
Use the butterfly method (Cross multiply):
b × 13 = 13b
65 × 7 = 455
So you would have:
13b = 455
Divide both sides by 13.
You will get b = 35
Hope this helps!
Answer: b=35
Step-by-step explanation:
[tex]\frac{b}{65}=\frac{7}{13}[/tex]
Multiply both sides by 65:
[tex]\frac{65b}{65}=\frac{7\cdot \:65}{13}[/tex]

Answer:
420 calories is your answer.
