The percentage of price of mangoes was increased by 15% from November to January.
<u>Step-by-step explanation:</u>
- The price of mangoes in November = $12 per kilo
- The price of mangoes in January = $18 per kilo
- The cost has been increased from $12 to $18.
Therefore, the change in percentage is percentage increase.
Percentage increase = (difference between two prices / lower price) × 100
⇒ (18-12 / 12) × 100
⇒ (6 / 12) × 100
⇒ 50 %
Therefore, the percentage change from November to January is increase of 50 %.
That would be true because the adjacent side to B is 4 and the hypotenuse is 5 and the formula for cos b is adjacent/hypotenuse
Hope this helps!

Step-by-step explanation:
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 .
