Answer:

See explanation

Step-by-step explanation:

1. The 1st Beatles song heard is the 5th song played means that first 4 songs are not Beatles songs (there are 100 - 10 = 90 such songs) and the 5th song is Beatles song (there are 10 such songs). Hence, the probability that the first Beatles song heard is the fifth song played is

\dfrac{C^{90}_4\cdot C^{10}_1}{C^{100}_5}=\dfrac{2,555,190\cdot 10}{75,287,520}\approx 0.3394

2. There are exactly two Beatles songs in the first five songs played means there are 2 Beatles songs and 3 not Betles songs (the number when these songs are played do not matter). Hence, the probability that there are exactly two Beatles songs in the first five songs played is

\dfrac{C^{10}_2\cdot C^{90}_3}{C^{100}_5}=\dfrac{45\cdot 117,480}{75,287,520}\approx 0.0702

Slope = -1/6; (12,-2)
stira [4]

Equation is y = -1/6x

Step-by-step explanation:

  • Step 1: Given that slope, m = -1/6 and a coordinate (12,-2). Write the equation and find the y-intercept, b.

⇒ y = mx + b

⇒ -2 = -1/6 × 12 + b

⇒ -2 = -2 + b

∴ b = 0

  • Step 2: Write the equation in slope intercept form.

⇒ y = -1/6x + 0

⇒ y = -1/6x

The area of a certain desert desert one is five times the area of another desert desert 2 if the sum of their areas is 24, 000,
sweet-ann [11.9K]

4,000,000 and 20,000,000 miles²

let x be the area of one desert then 5x is the area of the other

sum = x + 5x = 24,000,000

6x = 24,000,000

divide both sides by 6

x = 4,000,000

one desert is 4,000,000 miles²

and the other is (5 × 4,000,000)= 20,000,000 miles²
