Given :
Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
To Find :
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice.
Solution :
Amount of litre used in 14 days is :
V = 14× ( 1/4 )
V = 3.5 liter
Lowest price to pay is :
P = 2 × Cost of one 2 L carton
P = £(2 × 3.60)
P = £7.2
The lowest price Martin can pay for this juice is £7.2 .
Hence, this is the required solution.
Answer:
architects, builders, carpenters, plumbers, and electricians
Let x be a random variable representing the mean weight of a one-year-old Hereford bull. Then
a.) P(x < 1100) = P (z < (X - mean)/sd) = P(z < (1100 - 1150)/80) = P(z < -0.625) = 1 - P(z < 0.625) = 1 - 0.73401 = 0.2660
b.) The middle (50%) of Hereford weights will weigh the mean weight of the sample. i.e. the middle (50%) of the Hereford weights will be 1150 pounds
Answer:
5
Step-by-step explanation:
Original equation:
Divide both sides by 7
Rewrite in log
You can do mental math to realize this equals 5, or plug this into your calculate (if it allows you to set the base), but if you can't do either, you can use the change of base formula:
You get:
When you calculate using a calculator you should get 5
