Step-by-step explanation:

This event that's taking place is happening twice. The event is the mail getting delivered. It's happening two times. Luckily, you already know the probability of it happening once. Because it happens twice, you just square it. (0.9)^2. 0.81 chance of it happening in two consecutive days.

You make the exponent the amount of timeframe. for example since it is two consecutive days, it will be (0.90)^2. which is 0.81.

Use the model below to estimate the average annual growth rate of a certain country's population for 1950, 1988, and 2010, where

Morgarella [4.7K]

Answer:

The average annual growth rate of a certain country's population for 1950, 1988, and 2010 are 2.398, 0.9985 and 0.2236 respectively.

Step-by-step explanation:

The given equation is

$Y=-0.0000084x^3+0.00211x^2-0.205x+8.423$

Where Y is the annual growth rate of a certain country's population and x is the number of years after 1900.

Difference between 1950 and 1900 is 50.

Put x=50 in the given equation.

$Y=-0.0000084(50)^3+0.00211(50)^2-0.205(50)+8.423$

$Y=2.398$

Therefore the estimated average annual growth rate of the country's population for 1950 is 2.398.

Difference between 1988 and 1900 is 88.

Put x=88 in the given equation.

$Y=-0.0000084(88)^3+0.00211(88)^2-0.205(88)+8.423$

$Y=0.9984752\approx 0.9985$

Therefore the estimated average annual growth rate of the country's population for 1988 is 0.9985.

Difference between 2010 and 1900 is 110.

Put x=110 in the given equation.

$Y=-0.0000084(110)^3+0.00211(110)^2-0.205(110)+8.423$

$Y=0.2236$

Therefore the estimated average annual growth rate of the country's population for 2010 is 0.2236.

Natali5045456 [20]

Total units would be: 3+4 = 7

value of 1 unit = 28/7 = 4

ratio would be 3(4) & 4(4) = 12 & 16

AlexFokin [52]

Answer:

Hence option A and C are correct

Step-by-step explanation:

By putting value of 1.7 in each of the given equations of line as options should satisfy the equation

Option A

7– 7 = 3(1– 1)

0 = 0

Option B

y – 1 = 3(x – 7)

7-1 not equal to 3 (1-7)

Option C

y – 7 = 4(x – 1)

7 - 7 = 4 (1-1)

0 = 0

Option D

y – 1 = 4(x – 7)

7-1 is not equal to 4 (1-7)
