5. 1:175, if 2ft= 350 ft in life 1ft feet would probably be 175. (Cross multiplication)
6.a)100miles, 1 inch= 20mile so 5 inches multiplied by 20 miles gives you 100miles
b) 10 inches from Appleton. 1inch:20miles (cross multiply to get 10inches)
x :200miles
c)25000 miles will reach the equator so 50000 miles will go around the world! So, if 1inch:20miles,(50000/20=2500inches) And if 12inches:1ft, 2500inches * 1ft/12 inches to get 208.33.
7.a) 1inch:2.5miles(5inches*2.5miles/1) 5inches would be 12.5miles.
b)1inch:2.5miles, 41miles?. (1inch*41miles/2.5miles=x) x=16.4, so 41miles=16.4inches
c)No. Because they have different scales.
2463.01 would be the area for one circle just
Answer: 10.00
Step-by-step explanation:
You had to multiply and divide and see what you get.
Answer:
0.1587
Step-by-step explanation:
Here, mean=μ=100 and standard deviation=σ=16.
We have to find P(average MDI scores of 64 children > 102)=P(xbar>102).
n=64
μxbar=μ=100
σxbar=σ/√n=16/√64=16/8=2
P(xbar>102)=P((xbar-μxbar)/σxbar>(102-100)/2)
P(xbar>102)=P(z>1)
P(xbar>102)=P(0<z<∞)-P(0<z<1)
P(xbar>102)=0.5-0.3413
P(xbar>102)=0.1587
Thus, the probability that the average is greater than 102 is 15.87%
