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:

[tex]\sin(N) = 0.66[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

The total cost for the laptop for 3 years is $1174.20.

Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.

a × b means that a is added to itself b times or b is added to itself a times.

Given that,

Cost of the laptop when purchased = $780

Daily cost = $0.36

Number of days in 3 years = 3 × 365 = 1095 days

Cost for the laptop for 3 years = 1095 × $0.36

                                                   = $394.20

Total 3 year cost = $394.20 + $780

                            = $1174.20

Hence the total cost for the laptop is $1174.20.

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:

The equation is ( x² / 9 ) - ( y² / 7 ) = 1

Step-by-step explanation:

Given the data in question;

hyperbola is centered at the  origin, this means h and k are all equals to 0.

Vertices: (-3,0) and (3,0)

Since y-coordinates are constant, this implies it is a hyperbola with horizontal transverse axis.

h - a = -3

0 - a = -3

a = 3

Foci: (-4,0) and (4,0)

h - c = -4

0 - c = -4

c = 4

we know that, for a hyperbola

c² = a² + b²

so

⇒ ( 4 )² = ( 3 )² + b²

16 = 9 + b²

b² = 16 - 9

b² = 7

So the equation for the hyperbola will be;

⇒ ( (x-h)² / a² ) - ( (y-k)² / b² ) = 1

so we substitute

⇒ ( (x-0)² / 3² ) - ( (y-0)² / 7 ) = 1

⇒ ( x² / 3² ) - ( y² / 7 ) = 1

⇒ ( x² / 9 ) - ( y² / 7 ) = 1

Therefore, The equation is ( x² / 9 ) - ( y² / 7 ) = 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°

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:

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
