Otrada [13]3 years ago

B is the answer. Look at the first word, Conditional. That means that something has to happen in order to work. Such as, your parent making you do your chores before you can go play with your friends. Hence you have to win a first game in order to win a second.

A triangle has a perimeter of 51 cm. If the three sides of the triangle are n, 4n-4, and 4n-8, what is the length of each side?
True [87]

Answer:

see below

Step-by-step explanation:

The three sides add to 51

n      +    4n-4    +   4n-8   = 51

9n -12 = 51

9n = 63

n = 7        4n-4 = 24      4n-8 = 20

US Department of Transportation As part of a study on transportation safety, the US Department of Transportation collected data
Nonamiya [84]

Answer:

  • we can conclude that for every single unit of : x, y would be increased by 0.2871.  and intersection of x and y will be through =1.5974
  • it  can be  concluded that they are strongly positively correlated. There is strong and positive correlation between them. i.e the number of fatal accidents and the drivers under the age of 21

Step-by-step explanation:

WITH THE GIVEN DATA

A ) using regression to investigate the relationship between the number of fatal accidents and the percentage of drivers under the age pf 21

to fit into a regression line we must have ∝ and β

where β = \frac{S_{xy} }{S_{xx} }   = 0.2871

and ∝ = y - βx   =  - 1.5974

regression line = ∝ + β * x

insert values into regression line equation

regression line = -1.5974 + 0.2871 * x

we can conclude that for every single unit of : x, y would be increased by 0.2871.  and intersection of x and y will be through =1.5974

B ) conclusion and recommendations can you derive from your analysis

it  can be  concluded that they are strongly positively correlated. There is strong and positive correlation between them. i.e the number of fatal accidents and the drivers under the age of 21

using the correlation coefficient  ( r ) = \frac{S_{xy} }{\sqrt{S_{xx}*S_{xy}  } }    = 0.8394
