Answer:
14
Step-by-step explanation:
If we take Gabrielle's age as 2x and Mikhail's age as x, it equals to 3x. Divide 42 by 3, multiply by 1, you get 14.

A pool in the shape of a rectangular prism has a length of 12 m, a width of 6 m, and a depth of 1.5 m. Find the volume of water needed to fill the pool.
Answer:
108 m^3
Step-by-step explanation:
The volume of a rectangular prism is the product of all its sides. 12 * 6 * 1.5 = 108
A spinner has 14 equal sectors with different letters for each sector, as shown below:
Victoria spins the spinner 18 times, and it stops at the letter 'B' 10 times. If she spins the spinner a 20th time, what is the theoretical probability that this time it will stop at the letter 'B'?
PLZ SHOW WORK
BRAINLIEST PLEASE HELP
Answer:
1/14
Step-by-step explanation:
The sectors labeled are B, Y, G, C, P, F, O, V, M, A, D, E, H, and R.
Total number of sectors = 14.
When Victoria spins the spinner 18 times, and it stops at the letter B 10 times.
When Victoria spins the spinner the theoretical probability that this time it will stop at the letter B = Favourable outcomes ÷total number of outcomes.
Favourable outcomes =1 and Total number of outcomes = 14.
Hence Theoretical Probability = 1 over 14.

The data below represent commute timesâ (in minutes) and scores on aâ well-being survey. Complete partsâ (a) throughâ (d) below.
Commute Timeâ (minutes), x â 5 20 25 35 60 72 105
Well-Being Indexâ Score, y 69.1 67.8 67.1 66.6 65.0 65.0 62.3
Required:
Find theâ least-squares regression line treating the commuteâ time, x, as the explanatory variable and the indexâ score, y, as the response variable.
Answer:
y = - 0.0635x + 69.050 ;
For every unit increase in commute time, well being falls by 0.0635 on average ;
67.1
Step-by-step explanation:
Given :
Commute Time (minutes), x : 5 20 25 35 60 72 105
Well-Being Index Score, y : 69.1 67.8 67.1 66.6 65.0 65.0 62.3
The regression model obtained is :
y = - 0.0635x + 69.050
Where ;
y = Well being Index Score
x = Commute time
Slope = - 0.06352
Intercept = 69.0504
2.)
The slope value, - 0.0635 gives the rate of change in y per unit increase in x.
3.)
Well being Index for a person with commute time of 30 minutes
x = 30
y = - 0.06352(30) + 69.0504
y = 67.1448
y = 67.1 (1 decimal place)

[tex]Width = 11[/tex]
Required
The length
Area is calculated as:
[tex]Area = Length * Width[/tex]
Make Width, the subject

Milton purchases a 4-gallon aquariurn for his bedroom. To fill the aquarium with water, he uses a container with a capacity of 1 quart How many times will Milton fill and empty the container before the aquarium is full? Milton will fill and empty the container times.
Answer:
16 times
Step-by-step explanation:
Since he has a 4-gallon aquarium and a 1-quart container, and since there are 4 quarts in every gallon, he'll need to fill the aquarium with the container full 16 times because for every gallon, he'll need to fill the aquarium 4 times. This is the equation:
4*4=16 times
