Answer:

0.1248 = 12.48% probability of getting 3 blues.

Step-by-step explanation:

The M&Ms are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x successes is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of successes.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[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]

In this question:

7 + 4 + 4 + 2 + 3 + 3 = 23 total M&Ms, which means that [tex]N = 23[/tex]

Sample of 5 means that [tex]n = 5[/tex]

7 blue means that [tex]k = 7[/tex]

What is the probability of getting 3 blues?

This is P(X = 3).

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 3) = h(3,23,5,7) = \frac{C_{7,3}*C_{16,2}}{C_{23,5}} = 0.1248[/tex]

0.1248 = 12.48% probability of getting 3 blues.

Answer:

d. (600 - 81π) units ³

Step-by-step explanation:

Volume of the shaded portion = volume of triangular pyramid - volume of cone

= ⅓*A*h - ⅓πr²h

Where,

A = 15*10 = 150 units²

r = ½(9) = 4.5 units

h = 12

Plug in the values

Volume of the shaded portion = ⅓*150*12 - ⅓*π*4.5²*12

= (600 - 81π) units³

Answer:

Let the length of the sari be xm

cost of

2

1

=Rs 220

then cost of 1m=2(Rs220)=Rs440

Cost of the sari =x(Rs440)=Rs440x

But given that the cost of sari =Rs2640

Implies that

440x = 2640

Implies that

x=

Answer:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]

Step-by-step explanation:

Given

See attachment for Venn diagram

Required

Determine [tex]P(Foreign\ Language\ n\ Sport)[/tex]

First, we calculate the population of the set.

This is calculated as:

[tex]Total = Sport + Foreign\ Language + None + Both[/tex]

This gives

[tex]Total = 23 + 10 + 3+14[/tex]

[tex]Total = 50[/tex]

So, the required probability is:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{n(Foreign\ Language\ n\ Sport)}{Total}[/tex]

[tex]P(Foreign\ Language\ n\ Sport) = \frac{14}{50}[/tex]

14 represents the intersection between Foreign and Sport i.e. n(Foreign n Sport)

So, we have:

[tex]P(Foreign\ Language\ n\ Sport) = \frac{7}{25}[/tex]

Answer:

13 of August,

Step-by-step explanation:

All of them worked together at day number zero (August 1).

We know that Elvis works every 3rd day

So he will work at:

day 3, day 6, day 9, etc.

We know that Izzy works every 4th day, then she will work at:

day 4, day 8, day 12, etc.

We know that Janaisa works every 6th day, so she will work at:

day 6, day 12, etc.

We just need to find a day where the 3 of them work, this is equivalent to finding a common multiple of the numbers: 3, 4 and 6.

To do it, we can just write the multiples of each one of these numbers and see which one is the first common multiple:

3)

3*1 = 3

3*2 = 6

3*3 = 9

3*4 = 12

3*5 = 15

...

4)

4*1 = 4

4*2 = 8

4*3 = 12

4*4 = 16

...

6)

6*1 = 6

6*2 = 12

So we can see that 12 is a common multiple of the 3 numbers.

Then they will work together 12 days after August 1th.

That would be the 13 of August,

Answer:

52.38%

Step-by-step explanation:

P(991<X<997) = normalcdf(991,997,993,4) = 0.5328, therefore, about 52.38% of the bottles have volumes between 991 mL and 997 mL

The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%

Given that,

A bottler of drinking water fills plastic bottles with a mean volume of 993 milliliters (mL),

And standard deviation of 4 ml. The fill volumes are normally distributed.

We have to determine,

What proportion of bottles have volumes between 991 mL and 997 mL.

According to the question,

Mean of the drinking bottle = 993ml

[tex]\mu = 993[/tex]

And standard deviation of = 4 mL

[tex]\sigma = 4[/tex]

The proportion of bottles have volumes between 991 mL and 997 mL is,

[tex]= P (991<X<997) \\\\= P ( \dfrac{991-993}{4} <X < \dfrac{997-993}{4}) \\\\P( -0.5 < X < 1) = 0.5328 = 53.28\ percent[/tex]

Hence, The required proportion of bottles have volumes between 991 mL and 997 mL is 53.28%.

Answer:

x = 1    y = 3    z = 1

Step-by-step explanation:

(1)  x - 3y - z = -9           (2)   -2x + y + 2z = 3        (3)   2x + y + 3z = 8

                                2x(1)     2x - 6y - 2z = -18      (2)  -2x + y + 2z = 3

                                                 - 5y = -15                           2y + 5z = 11

                                                      y = 3                            2(3) + 5z = 11

                                                                                            6 + 5z = 11

                                                                                                  5z = 5

                                                                                                    z = 1

       x - 3(3) - 1 = -9

       x - 9 - 1 = -9

            x - 10 = -9

            x = 1

Answer:

A. 55°

Step-by-step explanation:

Complementary angles are angles that add up to give us 90°.

Since <A and <B are complementary angles, it implies that:

m<A + m<B = 90°

If m<A = 35°, therefore:

35° + m<B = 90°

Subtract 35° from each side

m<B = 90° - 35°

m<B = 55°
