Given that the<span> iq scores for large populations are centered at 100.
To get what percent of these 78 students have scores above 100 we conduct a normal distribution probability of the data.
P(x > 100) = P(z > (100 - 100)/sd) = P(z > 0) = 1 - P(z < 0) = 1 - 0.5 = 0.5 = 50%

Answer:
2.25
Step-by-step explanation: Replace the z with the value given (-18) and then multiply that by 1.1 you can then add it to 21.3 and then do the exponent
Sin 45=BC/1.3=.92
BC and AB are .92 cm
Area= .4225
Perimeter= 3.14

Answer:
5789 digits
Step-by-step explanation:
Given that the number of pages ares: 1,724
As we know that:
- (from 1 - 9) there are 9 one-digit numbers
- (from 10- 99) there are 90 two-digit numbers
- (from 100 - 999) there are 900 three-digit numbers
- (from 1,000 - 1,724) there are 725 four-digit numbers
So the total are:
