Answer: Probability of the arrow landing on a green colored section is \dfrac{1}{4}

Step-by-step explanation:

Since we have given that

Probability of the arrow landing on a section colored blue = \dfrac{6}{20}

Probability of the arrow landing on a section colored red = \dfrac{9}{20}

Since there are only three sections i.e. red, blue and green.

We need to find the probability of the arrow landing on a section colored green.

Required probability is given by

1-(\dfrac{9}{20}+\dfrac{6}{20})\\\\=1-\dfrac{15}{20}\\\\=\dfrac{20-15}{20}\\\\=\dfrac{5}{20}\\\\=\dfrac{1}{4}

Hence, Probability of the arrow landing on a green colored section is \dfrac{1}{4}

The answer would be 5/20 because you add the probability of red and blue (15/20), then subtract from the total (20) which would make it 5/20.

[x + 3y = -4] [2x + 6y = 5]
stealth61 [152]

Step-by-step explanation:

x+3y=-4(eqn1)

x=-4-3y

from (eqn 2)

2(-4-3y)+6y=5

-8-6y+6y=5

y=5+8=13.

y=13

from eqn 1

x+3(13)=-4

x+39=-4

x=-4-39

x=-43.

The value
ehidna [41]

Answer:

A

Step-by-step explanation:

Check the solution by substituting x = \frac{\pi }{2} into the left side of the equation

2sin²x - sinx - 1

= 2sin²(\frac{\pi }{2} ) - sin (\frac{\pi }{2} ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

= right side

\frac{\pi }{2} is therefore a solution to the equation

N which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?
OLEGan [10]

Answer:

53,901

Step-by-step explanation:

Here is the complete question :

In which number does the digit 5 have a value that is ten times greater than the value of the digit 5 in the number 245,093?

43,567

45,248

53,901

562,011

In the number 245,093 :

3 = units

9 = tens

0 = hundred

5 = thousand

4 = ten thousand

2 = hundred thousand

the value of 5 in the number is 5000. the number that would have a value that it 10 times greater than 5 in 245,093 must occupy the value  of ten thousand.

looking through the options, it is only in 53,901 that 5 occupies a value of ten thousand
