Answer:
6° F
Step-by-step explanation:
To get average of 10 days highs, we need to add all and divide by 10.
Average = 
And, the normal high temp is given as 82.
<em>How much higher is 88 than 82??</em>
<em />
It is 88 - 82 = 6°F above
Let x represent the amount of money he invested at 11% and y money he invested at 12%. Now we write system of equations:
x*1.11 + y*1.12 = 70 000 + 7900
x + y = 70 000
We will multiply second equation with 1.11
x*1.11 + y*1.11 = 77700
and subtract if from first:
0.01*y = 200
y = 20000
x = 70000 - 20000 = 50000
Answer:
92%
Step-by-step explanation:
The percentage of apartments rented for less than $600 is given by the sum of all of the apartments in the 300 to 400, 400 to 500 and 500 to 600 intervals divided by the total number of apartments sampled (250).

92% of the apartments rented for less than $600.
Answer: 3/7 is the pocket money he spends on sweets
Step-by-step explanation:
Let the amount student spends be x
He spends 17/35x on transport and fruits
He spends 5/6 (x - 17/35x) on sweets
5/6 * (x -17/35x)
5/6 * 18/35x
= 3/7x
Answer:
0.025
Step-by-step explanation:
-This is a conditional probability problem.
-Let L denote lens defect and C charging defect.
#We first calculate the probability of a camera having a lens defect;

#Calculate the probability of a camera having a charging defect:

The the probability that a camera has a lens defect given that it has a charging defect is calculated as:

Hence, the probability that a camera has a lens defect given that it has a charging defect is 0.025
