we call n - the number
2×n + 15 = 3×n + 8
2×n - 3×n = 8 - 15
-n = -7 │ ×(-1)
n=7
Two shaped are merged so
One is square and the other is trapezoid so,
AREA OF SQUARE=4*4
=16
AREA OF TRAPEZOID=(2+4)x4/2
So,rhe answer will be
12+16=28
HOPE IT IS HELPFUL
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.
Okay
Explanation : okayyyyyyyyyyyy
Answer:
8421
Step-by-step explanation:
8050 < abcd < 8500
We must have a = 8, so the number is 8bcd.
The value of a is 20 times the value of b, or a= 2b.
a = 8, so b = 4.
The value of b is 20 times the value of c, or b = 2c.
b = 4, so c = 2.
The value of c is 20 times the value of d, or c = 2d.
c = 2, so d = 1.
The secret number is 8421.
