Answer: 14 inches
Step-by-step explanation:
From the question, we are informed that a rectangle has a width of 2 inches and a length of 3 inches and has been scaled by a factor of 7.
This simply means that we've to multiply the width of the rectangle by 7 and also multiply the length of the rectangle by 7.
Old width = 2 inches
New width= 2 inches × 7 = 14 inches
The new width of the rectangle is 14 inches
Answer:
maybe its 30688399329932080?
Step-by-step explanation:
Exterior Angle Theorem: The measure of an exterior angle is equal to the sum of its 2 remote interior angles (That don't form a linear pair with it)
So its 25 + 90 = 115 (D)
ALSO it clearly cant be A because if you look at the angle, its greater than 90 degrees.

Answer:
0.8224
Step-by-step explanation:
Data
- standard deviation, sd: $10
- first value of interest, x1: $63
- second value of interest, x2: $90
z-score for x1:
z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3
z-score for x2:
z2 = (x2 - mean)/sd = (90 - 76)/10 = 1.4
The proportion of wrist watch prices are between $63 and $90 is:
P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)
P(z < 1.4) = 0.9192 (see first picture attached)
P(z < -1.3) = 0.0968 (see second picture attached)
P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224
