Answer:
-4
Step-by-step explanation:
arranging in ascending order
-20,-20,-17,-14,-4,2,7,7,13
number of terms=9
middle term= (n+1)/2=(9+1)/2=5th=-4
Answer:
-4
Step-by-step explanation:
To identify the media, you have to:
''Arrange your numbers in numerical order.
Count how many numbers you have.
If you have an odd number, divide by 2 and round up to get the position of the median number.
If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.''
If we follow the steps, the answer should be -4. With 9 data values, the middle number is the data value at position 5. And position 5 is -4. So the answer will be -4. Hope this helps !
Sarah made a certain number of bracelets for a craft show. Maria made 7 more than Sarah. Julie made 3 times as many as Maria. Which expression represents the total number of bracelets Julie made if Sarah made s bracelets?
Answer:
Total no of bracelets = 5s+28
Step-by-step explanation:
Let Sarah made s bracelets.
Maria made 7 more than Sarah i.e. 7+s
Julie made 3 times as many as Maria i.e. 3(7+s)
Total no of bracelets made is equal to the sum of the bracelets made by Sarah, Maria and Julie.
Total = s+ 7 + s + 3(7+s)
= 2s+7+21+3s
=2s+3s+21+7
= 5s+28
So, there are (5s+28) bracelets.
3.) 2x + 4 = -3x - 2; x = 1
Determine if the value of x is a solution to the equation
Answer:
x = 1 is not a solution to the equation
Step-by-step explanation:
2x + 4 = -3x - 2 x = 1
2(1) + 4 = -3(1) - 2
2 + 4 = -3 - 2
6 = -5 FALSE

A local little league has a total of 85 players, of whom 40% are left handed. How many left handed players are there ?
Answer: 34
Step-by-step explanation:
40 % is written as 0.4.
Multiply 0.4 x 85 (quantity) = 34
10x+50= 5x-25 solve for X
Answer:
-15
Step-by-step explanation:
10 x -15 = -150
-150 + 50 = -100
5 x -15 = -75
-75 - 25 = -100
A bank loans a customer $87,000 for a period of 15 years. The simple interest rate of the loan is 9.2%. What is the total amount that the customer will need to pay the bank over the 15 years?
Answer:
h. 207, 060
Step-by-step explanation:
Answer:
I= 120,060
Step-by-step explanation:
formula I=prt
Interest:
Principal: 87,000
rate:9.2% = 0.092
time: 15 year
I= 87,000(0.092) (15)
I= 87,000 (1.38)
I= 120,060
solve (x^3-4x)(2x^2-3x)
Answer:
= x^2 ( 2x^3- 3x^2 - 8x + 12)
Step-by-step explanation:
(x^3-4x) (2x^2-3x)
= x^3(2x^2-3x) -4x(2x^2-3x)
= 2x^5-3x^4-8x^3+12x^2
= x^2 ( 2x^3- 3x^2 - 8x + 12)
the sliding board is 15 feet long and meets the ground at a 40 degree angle. what is the height of the ladder?
Answer:
9.6 ft
Step-by-step explanation:
Sin=opposite/hypotenuse
The required height of the ladder is 9.6 feet.
Given that,
The sliding board is 15 feet long and meets the ground at a 40-degree angle.The height of the ladder is to be determined.
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
Here,
Let the height of the ladder be p
Now, applying trigonometric operations,
sin 40 = p / 15
p = 15 sin40
p = 0.64 * 15
p = 9.6
Thus, the required height of the ladder is 9.6 feet.

find the Sum of two consecutive odd numbers plus eighteen is 170
Answer:
75, 77
Step-by-step explanation:
Let the first odd number = 2x -1
Let the second odd number = 2x + 1
2x - 1 + 2x + 1 + 18 = 170 Combine like terms on the left.
4x + 18 = 170 Subtract 18 from both sides.
4x = 170 - 18 Combine like terms on the right
4x = 152 Divide by 4
4x/4 = 152/4
x = 38
2 * 38 - 1 = 75
2 * 38 + 1 = 77

Write the explicit formula for the arithmetic sequence 11, 14, 17, 20, . . . What is term number 54 in this sequence?
Answer:
Answer:
15 or 16. 54 is not listed.
Step-by-step explanation:
pretend that 11 is 0. that means 54 is 43.
then you do 43 divided by 3 or 43/3
but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.
Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.
Answer:
see explanation
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 11 and d = a₂ - a₁ = 14 - 11 = 3, then
[tex]a_{n}[/tex] = 11 + 3(n - 1) = 11 + 3n - 3 = 3n + 8
Thus
a₅₄ = 3(54) + 8 = 162 + 8 = 170

Find two numbers which differ by 4 and whose products is 45
Answer:
5, 9
Step-by-step explanation:
let
x= first number
y = second number
x- y= 4( equation 1)
xy=45( equation 2)
From equation 1
x= 4+y( equation 3)
put equation 3 into equation 2
( 4+y)y=45
4y+y^2=45
( y-5)(y+9)=0
y=5,-9
Then put y=5 into equation 3
x=9
Answer:
-9 and 5
Step-by-step explanation:
Let's call the first number N1 and the second number N2.
So, let's call N1 the smaller number and N1=x
Let's call N2 the larger number and N2=x+4.
X(X+4)=45
x^2+4x=45
x^2+4x-45=0
(x+9)(x-5)=0
X=-9, X=5
