Answer:
Step-by-step explanation:
CP=Rs 3000
SP=Rs 3300
since SP is greater than CP there is profit
profit%=sp-cp/cp*100%
=3300-3000/3000*100%
=300/3000*100%
=(300*100/3000)%
=30000/3000%
=10%
Answer:
10 percentStep-by-step explanation:
cp=Rs3000
sp=Rs3300
so cp<sp there is profit
profit=sp-cp
=Rs3300-Rs3000
=Rs300
Now
profit percent =profit × 100percent
cp
= 300 ×100
3000
=10percent

When 6 is subtracted from twice the
Sum of a number and 8 the result
is 5. Find the number.
According to the question,
The equation will be:
[tex](2x + 8) - 6 = 5[/tex]By solving the bracket, we get
→ [tex]2x + 8 - 6 = 5[/tex]

After a recent trip to the zoo, students were asked to write a statement about the big cats at the zoo.Which of the statements uses categorical data?
the answer is I don't know
Dean Kuroff started a business of rehabbing old homes. He recently purchased a circa-1800 Victorian mansion and converted it into a three-family residence. Yesterday, one of his tenants complained that the refrigerator was not working properly. Dean’s cash flow is not extensive, so he was not excited about purchasing a new refrigerator. He is considering two other options: purchase a used refrigerator or repair the current unit. He can purchase a new one for $600, and it will easily last three years. If he repairs the current one, he estimates a repair cost of $150, but he also believes that there is only a 25% chance that it will last a full three years and he will end up purchasing a new one anyway. If he buys a used refrigerator for $200, he estimates that there is a 0.4 probability that it will last at least three years. If it breaks down, he will still have the option of repairing it for $150 or buying a new one. Develop a decision tree for this situation and determine Dean’s optimal strategy.
Answer:
The decision tree is a explained as follows
Step-by-step explanation:
Currently two options are available
Purchase a new refrigerator for $600.Repair this refrigerator for $150, There is only 25% chance that the refrigerator will work for the next three years. $37.5 ($150 * 0.25) There is 75% chance that the refrigerator will need to be purchased a new refrigerator for $600. $450 ($600 * 75%)3. If he buys a used refrigerator for $200 there is 40% chance that it will work for next three years. $80 ($200 * 40%)
But there is 60% chance that the refrigerator will not work and he willa. Repair the refrigerator for $150. $90 ($150 * 60%)
b. Buy a new refrigerator for $600. $360 ($600 * 60%)

Joe swims 3 m North and then 5 m South. What is his distance? What is his displacement?
Swim
a) Distance: 8 m, Displacement: 2 m North.
b) Distance: 8 m, Displacement: 2 m South
c) Distance: 2 m, Displacement: 8 m North
d) Distance: 2 m, Displacement: 8 m South.
Answer:
Option "B" is the correct answer to the following question.
Step-by-step explanation:
Given:
Joe swim = 3 meter north
Jow swim = 5 meter south
Find:
Distance travel by Joe
Displacemnet by Joe
Computtaion:
The overall travel of an item without consideration to direction is called distance.
So,
Distance travel by Joe = 3 + 5
Distance travel by Joe = 8 meter
The term "displacement" refers to a shift in an object's location.
Displacemnet by Joe = 5 - 3
Displacemnet by Joe = 2 meter South
Consider the function f (x) = StartFraction x squared + 11 x minus 12 Over x minus 1 EndFraction.
Which statement describes the discontinuity at x = 1?
a jump discontinuity that cannot be removed by extending the function
an infinite discontinuity that cannot be removed by extending the function
a removable discontinuity that can be removed by extending the function to include f(1) = 13
a removable discontinuity that can be removed by extending the function to include f(1) = –11
IT'S C!
Answer:
"a removable discontinuity that can be removed by extending the function to include f(1) = 13"
Step-by-step explanation:
We have the function:
[tex]f(x) = \frac{x^2 + 11*x - 12}{x - 1}[/tex]
Here we have a problem when x = 1, because that makes the denominator to be equal to zero.
For now, let's see what happens to the numerator when x = 1
1^2 + 11*1 - 12 = 12 - 12 = 0
So x = 1 is a root of the numerator.
Let's find the other root of the numerator, here we can use Bhaskara's formula:
[tex]x = \frac{-11 \pm \sqrt{11^2 - 4*1*(-12)} }{2*1} = \frac{-11 \pm 13}{2}[/tex]
Then the two roots are:
x = (-11 + 13)/2 = 1
x = (-11 - 13)/2 = -12
And remember that a quadratic equation:
y = a*x^2 + b*x + c
With roots p and k, can be written as:
y = a*(x - p)*(x - k)
Then we can rewrite our numerator as:
1*(x - 1)*(x - (-12)) = (x - 1)*(x + 12)
Replacing that in the equation for f(x), we get:
[tex]f(x) = \frac{x^2 + 11*x - 12}{x - 1} = \frac{(x - 1)*(x + 12)}{(x - 1)} = \frac{x - 1}{x -1} *(x + 12)[/tex]
f(x) = x + 12
And, when evaluated in x = 1, we get:
f(1) = 1 + 12 = 13
Then the correct option is:
"a removable discontinuity that can be removed by extending the function to include f(1) = 13"

The 9th term of a sequence is 39, 366.
What is Geometric Progression?In mathematics, a sequence known as a geometric progression (GP) is one in which each following term is generated by multiplying each preceding term by a constant integer, known as a common ratio. This progression is sometimes referred to as a pattern-following geometric sequence of numbers.
We have the series: 6, 18, 54, ...
as, the series in Geometric Progression.
So, the common ratio = 18/6 = 3
and, 54/ 18= 3
Using the formula
[tex]a_n[/tex] = a[tex]r^{n-1[/tex]
So, for n= 9
[tex]a_9[/tex] = a[tex]r^{9-1[/tex]
[tex]a_9[/tex] = a[tex]r^{8[/tex]
[tex]a_9[/tex] = 6 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
[tex]a_9[/tex] = 39,336

A psychiatrist is interested in finding a 90% confidence interval for the tics per hour exhibited by children with Tourette syndrome. The data below show the tics in an observed hour for 13 randomly selected children with Tourette syndrome. The population standard deviation is σ=4.08.
Required:
a. To compute the confidence interval use a, z or t distribution?
b. With 90% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between ______ and _______ .
Answer:
a) z-distribution is used, as we have the standard deviation for the population.
b) Between [tex]\overline{x} - 1.86[/tex] and [tex]\overline{x} + 1.86[/tex], in which [tex]\overline{x}[/tex] is the sample mean of tics per hour.
Step-by-step explanation:
a. To compute the confidence interval use a, z or t distribution?
We have the standard deviation for the population, and thus, the z-distribution is used.
b. With 90% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between ______ and _______ .
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.9}{2} = 0.05[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.05 = 0.95[/tex], so Z = 1.645.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
[tex]M = 1.645\frac{4.08}{\sqrt{13}} = 1.86[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is [tex]\overline{x} - 1.86[/tex]
The upper end of the interval is the sample mean added to M. So it is [tex]\overline{x} + 1.86[/tex]
Between [tex]\overline{x} - 1.86[/tex] and [tex]\overline{x} + 1.86[/tex], in which [tex]\overline{x}[/tex] is the sample mean of tics per hour.

One bag contains 6 red, 2 blue, and 3 yellow balls. A second bag contains 2 red, 4 blue, and 5 yellow balls. A third bag contains 3 red, 7 blue, and 1 yellow ball. One bag is selected at random. If 1 ball is drawn from the selected bag, what is the probability that the ball drawn is yellow?
Using it's concept, it is found that there is a 0.2727 = 27.27% probability that the ball drawn is yellow.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that the probabilities are as follows:
1/3 probability of picking the first bag, then 3/11 probability of picking a yellow ball.1/3 probability of picking the second bag, then 5/11 probability of picking a yellow ball.1/3 probability of picking the third bag, then 1/11 probability of picking a yellow ball.Then, the probability of picking a yellow ball is given by:
[tex]p = \frac{1}{3}\left(\frac{3}{11} + \frac{5}{11} + \frac{1}{11}\right) = \frac{9}{33} = 0.2727[/tex]
0.2727 = 27.27% probability that the ball drawn is yellow.
