Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>
The answer is false.
Counterexample:
If a = 4 and b = 2
(4 - 2)^2 = 4
4^2 - 2^2 = 12
Since these answers are not the same this equation is false.
the answer is:
C. -23 + 6 = x
Step-by-step explanation:
- (-6) = + 6
Answer:
C. Over the course of many games, one would expect the mean number of hits per game to be the mean of the random variable.
Step-by-step explanation:
Mean is the ratio of sum of observations to the total number of observation.
It represent the whole data. Thus, Mean of hits per game is the mean of those hits of game. Thus, option C is correct.
mean is based on all the observation not few or most. Thus Option A is incorrect.
Observations are different from mean, So hits per game can be different from the mean of hits of game. Thus, Option B is incorrect.
The Mean of hits per game can be less and more from half of the observation. It is totally depends on the value of the observations. Thus, We can't chose option D as correct.
So firstly, we have to find out what 9% of $1,512 is. We can do this by multiplying 0.09(decimal form of 9%) and 1512 together, which gets you $136.08. This is the interest.
Next, add $136.08 and $1,512 together, which is 1648.08. This is the amount he needed to pay.
Now to find out how much he did pay, multiply 0.82 (decimal form of 82%) and 1648.08 together, which gets you 1351.43. $1351.43, or A, was the amount that Joel paid.
