Answer:
First, the classified triangle would be scalene triangle.
Step-by-step explanation:
Answer: X would equal 7 so X=7
Hey there!
So starting off we are going to take alllllll the numbers BEFORE the decimal, so in this case 987164.
Now 987164 represents the "ones" place.
Now lets do 3, 3 is going to represent AFTER the decimal, so 3 will be the "tens" place.
0 will be the hundreds
and 2 will be the thousands.

Answer:
The answer is D
Step-by-step explanation:
you have to find the square root of 390
Answer:
ŷ = 0.1286X - 123.2175 ;
r = 0.947
r² = 0.896
Step-by-step explanation:
Given the data:
Traffic Flow, X : ____Vehicke speed ;Y()
1257 ______________36
1329 ______________45
1227 ______________30
1336 ______________50
1349 ______________55
1124 ______________ 25
The estimated regression equation using a linear regression calculator based on the data given above is given thus:
ŷ = 0.1286X - 123.2175
Where ;
y = dependent variable (vehicle speed)
x = predictor variable (traffic flow)
Slope = 0.1286
Intercept = 123.2175
The correlation Coefficient, R, obtained using the correlation Coefficient calculator is 0.9465, This depicts a very strong positive relationship between traffic flow and vehicle speed.
The Coefficient of determination, R² which is the squared value of the correlation Coefficient = 0.9465² = 0.8958 gives the proportion of explained variance ; This means about 89.5% of variation in Vehicle speed can be explained by the regression line.
