Answer:
- The probability that the locker code begins with a prime number is 40%.
- The probability that the last digit of the locker code is an odd number is 40%
Step-by-step explanation:
- Prime numbers are the numbers that only divide with 1 or itself. So in this case it is 5 and 7.
The possible combinations are
1*4*3 (with 5) + 1*4*3(with 7) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
2. Odd numbers are those which don't divide with 2. So in this case it is 6 and 8.
The possible combinations are
1*4*3 (with 6) + 1*4*3(with 8) = 24
Total combinations are 5*4*3=60
(24/60)*100 = 40 %
1)Sin(29)=x/(30cm)
x=Sin(29)30cm
so be A is correct.
2) Cos A= a/b is correct because it is not true according to triangle.

Divide 4.55 by 0.13 (the cost of each bolt) to find out how many bolts Heidi can buy!
$4.55 ÷ $0.13 = 35
Heidi can buy 35 bolts with $4.55 !1

d dozen of eggs converted to numerical or variable expression:
=> There are 12pieces of eggs in 1 dozen, so
that is 12x1=12
=> Therefore, the numerical value is 12 x d or simply

We have:
z-score = 2.58
Proportion, p = 0.23
q = 1 - 0.23 = 0.77
Margin of error, E = 17% = 0.17
Step 1:
Multiply

by

= 0.23 × 0.77 = 0.1771
Step 2:
Divide z-score by the margin error = 2.58 ÷ 0.17 = 15.2
Step 3:
Square the answer from step 2 = 15.2² = 230.32
Step 4:
Multiply the answer from Step 1 by the answer in step 3
= 0.1771 × 230.32 = 40.79
The answer is the sample size is 40.79 rounded to 41
