Answer:
Jaime's wrong, becuase the distance(absolute value) from the point estimate to the lower bound is different than he distance from the upper bound to the point estimate.
Step-by-step explanation:
The distance(absolute value) from the point estimate to the lower bound must be the same as the distance from the upper bound to the point estimate.
The point estimate is 0.14.
Jaime
Jaime's interval has a lower bound of 0.049 and an upper bound of 0.191
upper - point = 0.191 - 0.14 = 0.051
point - lower = 0.14 - 0.049 = 0.091
Jaime's wrong, becuase the distance(absolute value) from the point estimate to the lower bound is different than he distance from the upper bound to the point estimate.
Mariya
Just to check.
Mariya's interval has a lower bound of 0.079 and an upper bound of 0.201.
upper - point = 0.201 - 0.14 = 0.061
point - lower = 0.14 - 0.079 = 0.061
Mariya has the same distances, so it is correct.
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
The first eight is in the thousands place and the second eight is in the hundreds place.
23.8 inches squared if im wrong sorry but what i did was i added 7.4 plus 7.4 cause there are two of the same side then did the same with 4.5
Slope-intercept form y = mx + b
where m------> slope
b-------> y-intercept
m= (y1-y2)/(x1-x2)
P1(-3,5) (x1,y1)
P2(2,10) (x2,y2)
m= (5-10)/(-3-2)
m= (-5)/(-5)
m=1
Until now, the equation is y=mx+b
y=1.x+b
y=x+b
But, whe can plug the point P2(2,10) in y =x+b
10 =2 + b
10 - 2 = b
b= 8
Then, the equation is y=mx+b
y= x+8 <-------------------Solution
Verification P1(-3,5) y = x+8 5=-3+8 Ok
P2(2,10) y = x +8 10 = 2+8 Ok
