Answer:
First blank: 4
Second blank: 3
Third blank: 8
Step-by-step explanation:
The expressions must be equivalent, yet one must read as 4 times the length of the box.
Looking at the given expression, 12x + 32, both numbers can be evenly divided by 4.
Since the blank spaces contain parenthesis, I can assume the problem is asking us to factor the numbers.
This means we put the number 4 on the outside of the parenthesis to display "4 times the side length."
4 × ? = 12
4 × 3 = 12
Substitute 12 for 3.
4 × ? = 32
4 × 8 = 32
Substitute 32 for 8.
4 (3x + 8)
1/3 x 2/4 = 2/12
For multiplying fractions do the top and bottom separately, so 1 x 2 and 3 x 4 giving the top part (numerator) as 2 and bottom part (denominator) as 12
Answer:
Step-by-step explanation:
standard deviation σ =5000
Mean μ = 36500
X = 30000
Probability that tire fails to reach 30000 miles
P(< 30000) = P( z < (30000-36500) / 5000 )
= P ( z < - 1.3 )
= .0968 ( from z table )
refund per mile = .01
refund for 30000 mile = .01 x 30000 = 300
expected cost of promotion
= 300 x .0968
= 29.04
b )
refund of $50 is equivalent to shortage of milage by 50 / .01 = 5000 miles
Probability of miles less than 30000 - 5000 = 25000
P ( X < 25000 ) = P ( z < (25000 - 36500) / 5000 )
P ( z < - 2.3 )
= 0.0107 Answer .
