Two point form:
y-(-7)/3-(-7)=x-6/-6-6
Rearrange to get y=-5/6x -2 (slope intercept form)
or y= 5x+6y=-12 (standard form)
Step-by-step explanation:
-x - 3 = x + 3
Solving like terms
-3 - 3 = x + x
-6 = 2x
-6 / 2 = x
-3 = x
The circumference is pi times diameter, so put 25.12 over pi to get the diameter. That would be 8. Then divide by 2 to get the radius. That would be 4
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
Remember that Interest is equal to

Subtracting the lower boundary of 1492 grams from the mean of 3234 gives you 1742 grams below the mean. Dividing 1742 by the standard deviation of 871 gives you 2 standard deviations below the curve. Now doing the same with the upper limit of 4976 grams also gives you 2 standard deviations above the mean (4976-3234)/871 = 2
So you now look for what percentage of the population lies within 2 standard deviations of the mean. Standard lookup tables will indicate that 95.4499736% of the population will be within 2Ď of the mean. So multiply 1278 by 0.954499736 giving 1219.851. Then round to the nearest whole number and you have an estimated 1220 babies that weigh between 1492 grams and 4976 grams.</span>
