Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.
Step-by-step explanation:
According to given statement;
Length of individual stringing beads = 0.19 inches
Rounding off = 0.2 inches
Length of row of 9 beads = 9* rounded off length of individual beads
Length of row of 9 beads = 9*0.2
Length of row of 9 beads = 1.80 inches
Since the beads are about 0.20 inches, the length of a row of 9 beads will be approximately 9 × 0.20 = 1.80 inches.

Answer:
soln,
price of textbook = $40
tax% = 10%
now,
tax amount = 10% of $40
= 10\100*40
= 10*4/10
= 40/10
= $4.
again,
final price = cost of textbook+tax
=$40+$4
=$44.
Step-by-step explanation:
so the total price of a Textbook is $40 which is 100% and the tax is 10% so you need to find tax from the price of the textbook which is 10% of the price of the textbook then add the price of the textbook with the tax amount which is the final cost .
Answer:
The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars is 0.0099
Step-by-step explanation:
A set of electric toothbrush prices are normally distributed with a mean of 87 dollars and a standard deviation of 8 dollars.
Standard deviation = 
We are supposed to find proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars i.e.P(104.60<x<108.20)
At x = 104.60
Z= 2.2
At x=108.20
Z= 2.65
Refer the z table for p value :
P(x<108.20)-P(x<104.60)=P(Z<2.65)-P(Z<2.2)=0.9960-0.9861=0.0099
Hence The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars is 0.0099
