The answer would be 3.75 or 15/4.
Answer:
y=(1/2)x-2
Step-by-step explanation:
Remember y=mx+b equation.
If is perpendicular to y=-2x+1 that has the slope -2, then the slope is negative reciprocal so is 1/2
Use the (x-x1)m= (y-y1) equation and the given point (2, -1),
so (x-2)1/2=(y+1); x-2=2y+2; 2y=x-2-2; 2y=x-4; y=(1/2)x-2
We know that
The Volume<span> is the </span>measurement<span> of how much space a three dimensional </span>object<span> takes up
</span><span>If the three dimensions are expressed in cm, the multiplication of the three measurements is
</span>cm*cm*cm--------> cm³
therefore
the answer is the option
cubic centimeters
Answer:
a)
b) 86.5 years
Step-by-step explanation:
All values are rounded to 2 decimal places
a) We can find line by using y =mx+b
Therefore the line of best fit is
b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005
Therefore the estimated life expectancy of someone born in 2005 is 86.5 years
PS. Please give brainliest answer this was a lot of working out
L = 0.403 is the lower end of the confidence interval
U = 0.487 is the upper end of the confidence interval
The margin of error E is
E = (U-L)/2
E = (0.487-0.403)/2
E = 0.042
Which is half the distance from the lower to upper end
---------------------------
The midpoint of the confidence interval is the value of (read out as "p hat")
phat = (U+L)/2
phat = (0.487+0.403)/2
phat = 0.445
---------------------------
Answer: The confidence interval (0.403, 0.487) can be rewritten into the form
