A window manufacturer claims that the seals break on only 4% of its windows. What is the probability that, in a sample of 10 windows, no seals will break?

0.96

Step-by-step explanation:

Total samples of window = 10smaples

Total seal break = 4% of 10

Total seal break = 0.04 * 10

Total seal break = 0.4

THis means that no seal will be break on 96% of the window i.e 9.6 windows

The probability that, in a sample of 10 windows, no seals will break is expressed

as;

Pr(no seal will break) = 9.6/10

Pr(no seal will break)  = 0.96

Hence the probability that no seals will break is 0.96

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The total nom of  code that can be used is equal to 5+3 = 8

Salesperson will make 6% of 1800

=(6/100)*1800

=108

Salesperson will make $108 in $1800 sales

Here,

tip=18%of $32

tip=(18/100)*32

=0.18*32

=$5.76

Total payment=32+5.76=$37.76

The wood before starting =12 feet

Left wood=6 feet

Wood used till now=12-6=6 feet

Picture frame built till now= 6/(3/4)

=8 pieces

Therefore, till now 8 pieces have been made.

The wood before starting =12 feet

Therefore, till now 8 pieces have been made.

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students
