15. Ankita bought 20 copy for Rs. 25 each. She got profit of Rs.200 while selling it. Find selling price of the copies.
Answer:
S.P = 225
Explanation:
Cost Price = 20 copies for Rs. 25
Selling price = 20 copies for ?
Profit = Rs. 200
Profit = S.P -C.P
Profit + C.P = S.P
200 + 25 = S.P
225 = S.P

1 lb = 16 ounces. A fourth of 16 is 4 (I found out by doing 16 / 4) therefore a one-fourth pound chicken weighs 4 oz.
I hope this helps!
Answer:
4 ounces
Step-by-step explanation:
one pound= 16 ounces
1/4th pound= [tex]\frac{1}{4} * 16[/tex]
= 4 ounces
Hence, [tex]\frac{1}{4}[/tex] pound = 4 ounces

The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62. In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35. (Round your answer to three decimal places)
Using the normal probability distribution and the central limit theorem, it is found that there is a 0.04 = 4% probability that the mean ticket price exceeds $35.
------------------------------------------
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
------------------------------------------
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
------------------------------------------
The average ticket price for a Spring Training baseball game is $32.61, with a standard deviation of $8.62.
This means that [tex]\mu = 32.61, \sigma = 8.62[/tex]
------------------------------------------
Sample of 40:
This means that [tex]n = 40, s = \frac{8.62}{\sqrt{40}}[/tex]
------------------------------------------
In a random sample of 40 Spring Training tickets, find the probability that the mean ticket price exceeds $35.
This is 1 subtracted by the p-value of Z when X = 35, so:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{35 - 32.61}{\frac{8.62}{\sqrt{40}}}[/tex]
[tex]Z = 1.754[/tex]
[tex]Z = 1.754[/tex] has a p-value of 0.96.
1 - 0.96 = 0.04
0.04 = 4% probability that the mean ticket price exceeds $35.

What is the least common multiple of 8, 17, and 14?
Answer:
952
Step-by-step explanation:
LCM(8,14) = (8 × 14) = (8 × 14) / 2 = 112 / 2 = 56
LCM(56,17) = (56 × 17)
= (56 × 17) / 1
= 952 / 1
= 952
Therefore,
LCM (Lowest common multiple) (8, 14, 17) = 952
The two vertices of a triangle are B(-3,1) and C(2,-2). If the coordinates of the intersection point H of the three heights are (9/11, 4/11), try to find the coordinates of another vertex A.
Answer:
(3,4)
Step-by-step explanation:
Find the equation of BH. (x+3)/(9/11+3)=(y-1)/(4/11-1)
(x+3)/(42/11)= (y-1)/(-7/11)
(x+3)*11/42= (y-1)*11/-7
x+3= -6(y-1)
x+3=-6y+6
y=-1/6x+1/2
m1=-1/6
AC: y=m2x+b
m1*m2=-1 (for perpendicular lines)
-1/6m2=-1
m2=6
-2=6*2+b
b=-14
y=6x-14
Find CH
(x-2)/(9/11-2)= (y+2)/(4/11+2)
(x-2)/(-13/11)= (y+2)/26/11
(x-2)*-11/13=(y+2)*11/26
(x-2)(-2)=y+2
-2x+4=y+2
y=-2x+2
m3=-2
AB: y=m4x+b
m3*m4=-1
-2*m4=-1
m4=0.5
Take the point B from AB
1=-3*0.5+b
b=2.5
y=0.5x+2.5
A is the point of intersection of two linesAB and AC
We have simultaneous equations
y=6x-14
y=0.5x+2.5
6x-14=0.5x+2.5
5.5x=16.5

Answer:
g(x) = 2sin(x) +3
Step-by-step explanation:
The transformation g(x) = c·f(x) +k represents a vertical scaling by a factor of c and a vertical shift by k units. You want the scale factor to be 2 and the vertical shift to be +3, so the transformed function is ...
g(x) = 2f(x) +3
g(x) = 2sin(x) +3

if 5-3(2a+1)=-4a+10, what is the value of a+2
Answer:
-2
BRAINLIEST, PLEASE!
Step-by-step explanation:
5 - 3(2a + 1) = -4a + 10
5 - 6a - 3 = -4a + 10
2 - 6a = -4a + 10
-2a = 8
a = -4
-4 + 2 = -2
Answer:
a+2 = -4+2 = -2
Step-by-step explanation:
5-3(2a+1)=-4a+10
Distribute
5 - 6a -3 = -4a +10
Combine like terms
-6a +2 = -4a +10
Add 6a to each side
-6a+2 +6a = -4a+6a +10
2 = 2a+10
Subtract 10 from each side
2-10 =2a+10-10
-8 = 2a
Divide by 2
-8/2 =2a/2
-4=a
11. Find the solutions of x^2-x-30 = 0.
Please give a walkthrough/step by step I am trying to learn how to do it!
To find the solutions of quadratic equation, there are two ways to do which are:
FactorizeQuadratic FormulaStep 1
- Factor the expression.
To factor the expression, refer below:
[tex] \displaystyle \large{ (x - a)(x - b) = {x}^{2} - bx - ax + ab}[/tex]
For bx and ax, both can be common-factored. Therefore
[tex] \displaystyle \large{ (x - a)(x - b) = {x}^{2} - (b + a)x + ab}[/tex]
From the above, we conclude that:
The middle term is b+aThe last term is a×bThus, we have to find two numbers that satisfy a+b and a×bFrom the expression, 30 comes from 5×6 and when 5-6 = -1. Therefore, a can be 5 and b can be 6.
[tex] \displaystyle \large{{x}^{2} - x - 30 = (x + 5)(x - 6)}[/tex]
Because in the middle term, it is -x which is negative, we have to let the highest number become negative.
From the factored expression:
The middle term = 5x + (-6x) = -xThe last term = 5 × (-6) = -30Then we replace the standard equation with factored form.
[tex] \displaystyle \large{ (x + 5)(x - 6) = 0}[/tex]
For this part, we solve like a linear equation where we isolate x. Just think you are solving two linear equations!
Hence
[tex] \displaystyle \large{ x = - 5, 6}[/tex]
Therefore, the solutions are x = -5, 6.
Evaluate using the order of operations. Show your work.

Answer:
27 square units
Step-by-step explanation:
The height is measured perpendicular to the base, so it is convenient to use a base such that the height is easily found. Here, the vertical line is a suitable base, as the height is the horizontal distance from that to the opposite vertex.
A = 1/2bh = 1/2(9)(6) = 27 . . . . square units = triangle area

The length of a rectangle is 2 cm more than 5
times the width. The perimeter is 196 cm. Find
the width and length.
length = 82 cm
width = 16 cm
Step-by-step explanation:
x = length
y = width
the perimeter of a rectangle is the lengths of all sides added together. so, 2×length plus 2× width
x = 5y + 2
196 = 2x + 2y
let's use the first equation as substitute in the second equation.
196 = 2×(5y + 2) + 2y = 10y + 4 + 2y = 12y + 4
12y = 192
y = 16 cm
x = 5y + 2 = 5×16 + 2 = 80 + 2 = 82 cm
