The three children are x, 2x, and x+5
So set up an equation: x+2x+x+5=57
Solve: 4x=52 so x=13
So the ages are...

13, 18, 26

Check: 13+18+26=57

Two fair dice are tossed, and the up face on each die is recorded. Find the probability of observing each of the following event

Paladinen [302]

Answer:

Step-by-step explanation:

The sample space is shown in the attached photo.

Probability = number of favourable outcomes/total number of outcomes.

Looking at the diagram, the total possible outcomes is 36.

A) from the diagram, the total number of events in which the sum of the numbers is odd is 18. Therefore, the probability that the sum of the numbers is odd is

18/36 = 1/2

B) the total number of events in which the sum of the numbers is 10 or more is 6. Therefore, the probability that the sum of the numbers is 10 or more is

6/36 = 1/6

C) the total number of events in which 3 appears on each of the two dice is 1. Therefore, the probability that 3 appears on each of the two dice is

1/36

*NEED HELP??!!! The regression equation y = 3.648 • 1.182x approximates the cost to go on a safari, y, given the number of years

Ghella [55]

Answer:

D) $9.95

Corrected question;

! The regression equation y = 3.648 • 1.182^x approximates the cost to go on a safari, y, given the number of years since it opened in 2005, x. Which is the best estimate for the cost of a vehicle to drive through the safari in 2011?

Step-by-step explanation:

Given;

The regression equation

y = 3.648 • 1.182^x

Where;

x = number of years since it opened in 2005

y = the cost to go on a safari

For this case;

x at 2011 = 2011 - 2005

x = 6 years

Substituting into the regression equation;

y = 3.648 × 1.182^(6)

y = 9.948547753694156132352

y = $9.95
