Answer:

c. 0.3974

Step-by-step explanation:

Given;

number of white balls, W = 17

number of red balls, R = 18

Total number of balls, T = 35

The number of ways the event will occur is given by

= P(2 whites) and P(2 reds)

= P(2whites) x P(2 reds)

= 17C2 x 18C2

= 136 x 153

= 20,808

The total number of possible outcome

= 35C4

= 52,360

The probability = 20,808 / 52,360

                          = 0.3974

The correct option is "C"

Probability that the sample contains two white balls and two red ones is equal to 0.3974.

So, option c. is correct.

Probability is a discipline of mathematics concerned with numerical explanations of the likelihood of an event occurring or the truth of a claim.

Number of white balls [tex]=\boldsymbol{17}[/tex]

Number of red balls [tex]=\boldsymbol{18}[/tex]

Total number of balls [tex]=\boldsymbol{35}[/tex]

Probability that the sample contains two white balls and two red ones  

[tex]=\frac{\binom{17}{2}\binom{18}{2}}{\binom{35}{4}}[/tex]

[tex]=\frac{\frac{17!}{15!2!}\frac{18!}{16!2!}}{\binom{35!}{31!4!}}[/tex]

[tex]=\boldsymbol{0.3974}[/tex]

So, option c. is correct.

Step-by-step explanation:

Answer:

The central angle of the sector is 0.5 radian

Step-by-step explanation:

given;

radius of the circle, r = 80 mi

area of the sector, A = 1600 mi²

Area of sector is given by;

A = ¹/₂r²θ

where;

θ is the central angle (in radians) of the sector

[tex]\theta = \frac{2A}{r^2}\\\\\theta = \frac{2*1600}{80^2}\\\\ \theta = 0.5 \ radian[/tex]

Therefore, the central angle of the sector is 0.5 radian

The central angle (in radians) of the sector is 28.66 degrees

The formula for calculating the area of a sector is expressed as:

[tex]A = \theta/360 \times \pi r^2[/tex]

Given the following parameters

radius r = 80mi

Area of sector A = 1600mi²

Substitute the given parameters into the formula

1600 = Ф/360 * (3.14)(80)²

1600 * 360 = 20,096Ф

Ф = 576000/20,096

Ф =28.66 degrees

Hence the central angle (in radians) of the sector is 28.66 degrees

The total cost would be $9.45

Step-by-step explanation:

Answer:

well, there is already $900 so 1800-900=900   now we need 4% of 900 which is $36   900 divided by 36 is 25

it will take 25 years

Step-by-step explanation:

plz mark brainliest i answered first

The number of years that will it take for the value of the account to reach $1,800 should be 25 years.

Since the deposited amount is $900

The rate of interest is 4%

The future value is $1,800

So here the balance amount should be

= $1,800 - $900

= $900

Now 4% of $900 = 36

So the number of year should be

= [tex]900\div 36[/tex]

= 25 years

hence, The number of years that will it take for the value of the account to reach $1,800 should be 25 years.

y=x^2+1 (Graph Example), 4x+2=2(x+6) (Solve Example)

Answer:

y(0) = 3

Step-by-step explanation:

This is solved by plugging in each option one by one, and seeing which one results in a positive value for dy/dt.

dy/dt = (4 − 1) (1 − 2²) = -9

dy/dt = (7 − 1) (1 − 1²) = 0

dy/dt = (1 − 1) (1 − 2²) = 0

dy/dt = (-4 − 1) (1 − 0²) = -5

dy/dt = (3 − 1) (1 − 0²) = 2

Only the last option fits.
