So far this year, a company has sold 8.28×10^5 tablet computers. How many more tablets must the company sell for it's tablet sales to reach 1 million thisyear? Explain how you solved this problem
The standard
form of 8.28 × 105
is 828,000. Subtract this number
from 1 million: 1,000,000 - 828,000 = 172,000.
Answer: 172,000 or 1.72 × 105
The median is 9. mode is 7
Answer:
0.9544
Step-by-step explanation:
We are given that mean=18 and standard deviation=1 and we have to find P(16<X<20).
P(16<X<20)=P(z1<Z<z2)
z1=(x1-mean)/standard deviation
z1=(16-18)/1=-2
z2=(x2-mean)/standard deviation
z2=(20-18)/1=2
P(16<X<20)=P(z1<Z<z2)=P(-2<Z<2)
P(16<X<20)=P(-2<Z<0)+P(0<Z<2)
P(16<X<20)=0.4772+0.4772=0.9544
The probability that the height of a tree is between 16 and 20 feet is 95.44%
