worty [1.4K]

Answer:

2080

Step-by-step explanation:

The solution to these equations might best be found using Cramer's Rule. It tells you ...

x = (56939×3 -41655×2)/(-236×3 +838×2) = 87507/968 ≈ 90.400

This is years after 1990, so the year the incomes become the same is predicted to be ...

1990 +90.4 = 2080.4

The median incomes will be the same in the year 2080.

The 90km/h bus runs between the two stations in 2 hours and 20 minutes.

AnnZ [28]

Answer:

1. distance is 210km

2. distance is 163•3km

Step-by-step explanation:

SPEED=DISTANCE÷TIME

90km/h= X ÷ 2 hrs and 20mins

CHANGE 20 MINS INTO HRS

1 hr = 60mins

? = 20mins

20mins * 1hr= 1/3hr

60mins

Speed=distance÷time

90km/h= X ÷ 21/3

Distance= speed * time

X = 90km/h * 21/3hrs

distance is 210km

Speed=distance ÷

70km/h= X ÷ 21/3hrs

Distance=speed * time

X = 70km/h * 21/3hrs

JulijaS [17]

Answer: 0.3125.

Step-by-step explanation:

The chance of having a boy is 0.5,
the chance of having a girl is also 0.5.

Outcome 1: all boys

boy boy boy boy

0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Outcome 2: first child is a girl, all others are boys

girl boy boy boy

0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Outcome 3: second child is a girl, all others are boys

boy girl boy boy

0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Outcome 4: third child is a girl, all others are boys

boy boy girl boy

0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Outcome 5: fourth child is a girl, all others are boys

boy boy boy girl

0.5 * 0.5 * 0.5 * 0.5 = 0.0625

Therefore,

0.0625 + 0.0625 + 0.0625 + 0.0625 + 0.0625 = 0.0625 * 5 = 0.3125
