Rohan bought an almirah for Rs 15,600 and spent Rs 400 on its transportation. The total C.P is __________
Answers
From the question,
Rohan bought an almirah for =Rs.13600= cost price
Transportation cost =Rs.400
The total cost price of almirah =Rs.(13600+400)
The total cost price of almirah =Rs.(13600+400)=Rs.14000
He sold it for =Rs.16800= selling price
By comparing SP and CP=SP>CP, so there is a gain
Gain=SP−CP
=16800−14000
=Rs.2800
Gain %={(gain/CP)×100}
={(2800/14000)×100}
={2800/140}
=20%
The average of 15 test scores is 80. If the average of first eight test scores is 65 and that of the last eight test scores is 70, then the eighth score is 80.
True or False?
Answers
Answer:
FalseStep-by-step explanation:
The average of 15 test scores is 80.
The total is:
15*80 = 1200The average of first eight test scores is 65.
The total is:
8*65 = 520The average of last eight test scores is 70.
The total minus 8th score is:
8*70 - 80 = 480The sum gives us the total of 15 scores:
520 + 480 = 1000 < 1200The answer is FALSE

An industrial psychologist consulting with Lara music stores knows that the average number of complaints management receives each month throughout the industry is 6, but the standard deviation is unknown. Twenty of the Lara music stores were randomly selected to record complaints for one month; the mean of this sample was 3 and its standard deviation was 1.5. Using the .05 significance level, is the number of complaints received by Lara music stores different from the number of complaints received by music stores in general
Answers
Answer:
Step-by-step explanation:
H0 : μ ≥ 6
H1 : μ < 6
Test statistic :
n = 20
Sample Mean, x = 3
σ = 1.5
Test statistic = (x - μ) ÷ σ/sqrt(n)
Test statistic = (3 - 6) ÷ 1.5/sqrt(20)
Test statistic = - 3 / 0.3354101
Test statistic = −8.944271
Since, sample size is < 30 ;
Obtaining the Critical value using the from T;
Tcritical at 0.05, df = 19 = - 1.729
Tstatistic < Tcritical
−8.944271 < - 1.729
Hence, we reject the Null:
We can conclude that there is significant evidence that the number of complaints received by Lara music store is different from number of complaints received by music stores in general.
You buy a $90 item and it is discounted by $18. What is the discount's percentage?
Answers
Answer:
Hey the answer is 20%.
Step-by-step explanation:
You multiply the $90 with 20%,
but in order to figure that out you need to:
Calculate the savings: 20% of $90 = $18.
Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!

D.
(x − 10)2 = 21
Answers
I just want to mention that the question is wrongly written!
it's meant to be x² − 10x − 11 = 0 and not x2 − 10x − 11 = 0
and so the other equations!
Answer:
The answer is B: (x − 5)² = 36
Step-by-step explanation:
by solving the equations using the quadratic formula we found:
the solutions for x² − 10x − 11 = 0 | x = 11, -1
the solutions for A | x = 16, 4
the solutions for B | x = 11, -1
the solutions for C | x = [tex]\sqrt{21} +5[/tex], [tex]-\sqrt{21}+5[/tex]
the solutions for D | x = [tex]\sqrt{21}+10, -\sqrt{21}+10[/tex]
the given equation: x² − 10x − 11 = 0 and the equation B: (x − 5)² = 36 have the same solutions
Therfore B is the correct answer

Answer:
13.9
Step-by-step explanation:
Use the distance formula:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\[/tex]
The square root of 193 rounded to the nearest tenth is 13.9.

[tex]\boxed {\boxed {\sf 3 \ pounds \ of \$4 \ candy}}[/tex]
[tex]\boxed {\boxed {\sf 2.5 \ pounds \ of \$3.50 \ candy}}[/tex]
Step-by-step explanation:
Let's create a system of equation. First, define the variables. One type of candy is x and the other is y.
Now, create 2 equations, one for the weight and one for the price.
[tex]x+y=5.5[/tex]
[tex]4x+3.5y=20.75[/tex]
The first equation represents the mixture of both types of candy that weighs 5.5 pounds. The second represents the prices of the candy and the mixture.
Next. solve for the variables using substitution. Isolate a variable in the first equation. Let's isolate y by subtracting x.
[tex]x-x+y=5.5-x\\y= 5.5-x[/tex]
Now, we know what y is equal to, so we can substitute it into the second equation.
[tex]4x+ 3.5 (5.5-x)= 20.75[/tex]
Distribute the 3.5. Multiply each term by 3.5
[tex]4x+(3.5*5.5)+(3.5*-x)[/tex]
[tex]4x+19.25-3.5x= 20.75[/tex]
Combine like terms on the right side.
[tex]0.5x+19.25=20.75[/tex]
Subtract 19.25 from both sides of the equation to isolate the variable.
[tex]0.5x+19.25-19.25=20.75-19.25[/tex]
[tex]0.5x= 1.5[/tex]
Divide both sides by 0.5.
[tex]\frac {0.5x}{0.5}= \frac{1.5}{0.5}\\x=3[/tex]
Now we can substitute x back into the first equation and solve for y.
[tex]x+y=5.5\\3+y=5.5[/tex]
Subtract 3 from both sides to isolate the variable.
[tex]3-3+y=5.5-3\\y=2.5[/tex]
There was 3 pounds of the $4 candy and 2.5 pounds of the $3.50 candy.

If an equilateral triangle has a height of 8 metres find the length of each side. Round your answer to 2 decimal places.
Answers
Answer:
9.24 m to 2 DP's.
Step-by-step explanation:
Consider the right triangle formed from a side , altitude and 1/2 the base.
By pythagoras:
x^2 = 8^2 + (0.5x)^2 where x is the length of each side.
x^2 - 0.25x^2 = 64
0.75x^2 = 64
x^2 = 64/0.75 = 85.3333.
x = 9.2376 m.
What are all of the zeros in this equation?
Answers
Answer:
0, 1 and 1
Step-by-step explanation:
Given the expressions;
x^3-2x^2+x = 0
x(x^2-2x+1) = 0
x = 0 and x^2-2x+1 = 0
Factorize x^2-2x+1 = 0
x^2-x-x+1 = 0
x(x-1)-1(x-1) = 0
(x-1)(x-1)= 0
x = 1 twice
hence the zeros of the equation are 0, 1 and 1
