Answer:
A) The actual length of the microchip is 3 centimeters.
B) The actual width of the microchip is 2 centimeters
C) The ratio of the original scale drawing measurements to the new scale drawing measurements is 2 inches to 3 inches.
Step-by-step explanation:
A) actual length = scale length × reciprocal of scale factor
The scale is 2 inches to 1 centimeter, so the scale factor is. 2in/1cm The reciprocal of the scale factor is. 1cm/2in The length of the chip in the scale drawing is 6 inches.
= 6 in. x (1cm/2in)
= 3 cm
B) actual width = scale width × reciprocal of scale factor
= 4 in. x (1cm/2in)
= 2 cm
C) The original scale drawing, the microchip was 6 inches long. It is now 9 inches long.
Ratio: 6in/9 in 3in/2in
The microchip was 4 inches wide. In the new scale drawing, the microchip is 6 inches wide.
Ratio: 4in/6in 2in/3in
Answer:
0.9973
Step-by-step explanation:
Given :
Probability of girl, probability of success , 1 - p = 1 - 0.519 = 0.481
1 - p = 0.481
n = 9
Probability that atleast one is girl
Usingbthe binomial probability distribution :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
USing the binomial probability calculator :
p(x ≥ 1) = p(x=1) + p(x=2) + p(x=3) + p(x=4) + p(x=5) + p(x=6) + p(x=7) + p(x=8) + p(x=9)
p(x ≥ 1) = 0.9973 ( from calculator).
