Answer: Loss, 200 Rs

Step-by-step explanation:

Given

Sharad bought  a quintal of onion i.e. [tex]1000\ kg[/tex] for [tex]Rs.\ 2000[/tex]

So, the cost price of onion is

[tex]\Rightarrow \dfrac{2000}{100}=20\ \text{Rs per kg}[/tex]

He sells it at [tex]18\ \text{Rs. per kg}[/tex]

Here, the Selling price is less than the cost price

So, he incurs a loss of [tex]2\ \text{Rs per kg}[/tex]

For a quintal it is

[tex]\Rightarrow 2\times 100=200\ \text{Rs}[/tex]

[tex]\Rightarrow \text{Loss }\ \%=\dfrac{C.P.-S.P.}{C.P.}\times 100\\\\\Rightarrow \text{Loss }\ \%=\dfrac{20-18}{20}\times 100=10\%[/tex]

Answer:

4 1/2

Step-by-step explanation:

.

Answer:

4 1/2

Step-by-step explanation:

9/2 as a mixed fraction.

= 9 ÷ 2

= 4 which leaves a remainder of 1

▪Take the 4 as the whole number, take the remainder 1 and place it over the denominator which is 2

You then get your answer.

4 1/2

Answer:

Standard deviation = 0.59

Step-by-step explanation:

Given data → 5.6, 5.2, 4.6, 4.9, 5.7, 6.4

Mean of the given data = [tex]\frac{5.6+5.2+4.6+4.9+5.7+6.4}{6}[/tex]

                                       = 5.4

   Data (x)              (x - mean)            (x - mean)²

     5.6             5.6 - 5.4 = 0.2             (0.2)² = 0.04

     5.2             5.2 - 5.4 = -0.2            (-0.2)² = 0.04

     4.6             4.6 - 5.4 = -0.8            (-0.8)² = 0.64

     4.9             4.9 - 5.4 = -0.5            (-0.5)² = 0.25

     5.7             5.7 - 5.4 = -0.3             (-0.3)² = 0.09

     6.4             6.4 - 5.4 = 1                  (1)² = 1

  N = 6                                                [tex]\sum (x-mean)^2[/tex] = 2.06

Since, Standard deviation = [tex]\sqrt{\frac{\sum (x-mean)^2}{N}}[/tex]

                                           = [tex]\sqrt{\frac{2.06}{6} }[/tex]

                                           = 0.5859

                                           ≈ 0.59

Answer:

16 units²

Step-by-step explanation:

Area of the right triangle = ½ × base × height

base = 8

height = 4

Substitute

Area = ½ × 8 × 4

Area = ½ × 32

Area = 16 units²

Answer:

The bolts with diameter less than 5.57 millimeters and with diameter greater than 5.85 millimeters should be rejected.

Step-by-step explanation:

We have been given that the diameters of bolts produced in a machine shop are normally distributed with a mean of 5.71 millimeters and a standard deviation of 0.08 millimeters.

Let us find the sample score that corresponds to z-score of bottom 4%.

From normal distribution table we got z-score corresponding to bottom 4% is -1.75 and z-score corresponding to top 4% or data above 96% is 1.75.

Upon substituting these values in z-score formula we will get our sample scores (x) as:

Therefore, the bolts with diameters less than 5.57 millimeters should be rejected.

Now let us find sample score corresponding to z-score of 1.75 as upper limit.

Therefore, the bolts with diameters greater than 5.85 millimeters should be rejected

Answer:

6.30 millimeters and 6.50 millimeters.

Answer:

  (b)  10.5 in

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3πr²h . . . . . . for radius r and height h

Then the height is ...

  h = 3V/(πr²)

Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...

  h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in

The height of the cone is about 10.5 inches.

Answer:

M=1

Step-by-step explanation:

m-1/4=3/4 add 1/4 to both sides and you get m=1

Answer:

M = 1

Step-by-step explanation:

M-1/4=3/4

add 1/4 to both sides of the equation:

M - 1/4 + 1/4 = 3/4 + 1/4

simplify:

M = 1

Answer:

B

Step-by-step explanation:

Anything times zero is zero, so any whole number can be the second one so long as the first is 0.

The sum doesnt have to equal zero because non zero numbers multiplied by zero still equal zero.

Answer:

i think 80

Step-by-step explanation:

Answer:

a) Trials are independent, and there is a fixed number of trials, which means that the binomial probability distribution can be used.

b) 0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

a)

For each senior, there are only two possible outcomes. Either they disapprove daily pot smoking, or they do not. The seniors are selected at random, which means that the probability of one disapproving daily pot smoking is independent of other seniors, that is, the trials are independent. There is also a fixed number of trials.

b)

70% disapprove of daily pot smoking, according to a report in Parade, which means that [tex]p = 0.7[/tex]

12 seniors means that [tex]n = 12[/tex]

The probability is P(X = 1).

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{12,1}.(0.7)^{1}.(0.3)^{11} = 0.000015[/tex]

0.000015 = 0.0015% probability that exactly one of the 12 seniors disapproves daily pot smoking
