Answer:
8x + 24
Step-by-step explanation:
Given photograph length L = 7" and width W = 5"
Also that the frame is 2x" longer and 2x" wider
hence,
new length = ( 7 + 2x) inches
new width= ( 5 + 2x) inches
Hence perimeter of frame,
= 2 x ( new length + new width)
= 2 [( 7 + 2x) + ( 5 + 2x)]
= 2 (4x + 12)
= 8x + 24 (Answer)
A full rotation is represented by 360 degrees or 2pi radians, so
2/3 of a full rotation is repr. by (2/3)(360 deg) or (2/3)(2pi rad). (Simplify these.)
Answer:
a) the value of 135 because it is not greater than 136.5
Step-by-step explanation:
Given that
n = sample size =85
Mean = 146
std dev =34
Std error of sample = 34/sqrt 85
= 3.6878
99% z critical value = 2.58
Margin of error = ±9.515
Confidence interval lower bound = 146-9.515 = 136.485
Upper bound = 146+9.515 =155.515
Hence we find that 135 is less than lower bound, hence 135 does not lie within 99% confidence interval
a) the value of 135 because it is not greater than 136.5
