According to the line of best fit, the value of time when the temperature reach 100°c, the boiling point of water is 5.
<h3>What is linear regression?</h3>
Linear regression is a type of regression which is used to model the statement in which the growth or decay initially with constant rate, and then slow down with respect to time.
The table shows the temperature of an amount of water set on a stove to boil, recorded every half minute. a 2-row table with 10 columns.
- Time (minutes X) 0, 0.5,1.0, 1.5, 2.0,2.5,3.0, 3.5, 4, 4.5.
- Temperature (° Celsius Y) 75, 79, 83, 86, 89, 91, 93, 94, 95, 95.5.
The sum of time is 22.5 and the sum of temperature value is 880.5. In this table,
- The mean of time value, 2.25.
- The mean of temperature value 88.05
- Sum of squares 20.625
- Sum of products 93.625
The regression equation for this data can be given as,
![\hat y=4.53939 X+77.83636](https://tex.z-dn.net/?f=%5Chat%20y%3D4.53939%20X%2B77.83636)
Put the value of temperature (y) 100 in this equation.
![100=4.53939 X+77.83636\\X=\dfrac{100-77.83636}{4.53939}\\X\approx 5](https://tex.z-dn.net/?f=100%3D4.53939%20X%2B77.83636%5C%5CX%3D%5Cdfrac%7B100-77.83636%7D%7B4.53939%7D%5C%5CX%5Capprox%205)
Hence, according to the line of best fit, the value of time when the temperature reach 100°c, the boiling point of water is 5.

Answer:
3 1/3 gum balls per friend
Step-by-step explanation:
Packs of gum balls Pete has = 4
Each pack = 5 gum balls
Total gum balls Pete has = Number of packs of gum balls × Number of gum balls in each pack
= 4 × 5
= 20 gum balls
Pete gives the same number of gum balls to 6 friends.
Each friend gets = Total gum balls / number of friends
= 20 gum balls / 6 friends
= 3 2/6 gum balls per friend
= 3 1/3 gum balls per friend
Answer:
4th Option, 45.1
Step-by-step explanation:
Cos(Ф) = ![\frac{12}{17}](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B17%7D)
Ф = Cos⁻¹ (
)
Ф = 45.1
