14x + 10y = 72
14x + 4y = 96
6y = -24
6 6
y = -4
14x + 10y = 72
14x + 10(-4) = 72
14x - 40 = 72
+ 40 + 40
14x = 112
14 14
x = 8
(x, y) = (8, -4)
Answer:
The hypothesis test is right-tailed
Step-by-step explanation:
To identify a one tailed test, the claim in the case study tests for the either of the two options of greater or less than the mean value in the null hypothesis.
While for a two tailed test, the claim always test for both options: greater and less than the mean value.
Thus given this: H0:X=10.2, Ha:X>10.2, there is only the option of > in the alternative claim thus it is a one tailed hypothesis test and right tailed.
A test with the greater than option is right tailed while that with the less than option is left tailed.

Answer:
<h3>
Let's start with the total money needed for basketballs</h3>
The total money the coach will need for 40 basketballs will be 40 times price of one basketball.
Thus we need to find the price of one basketball.
$27 for 3 basketballs
Thus for one basketball,
Which gives us,
'9'.
So for 40 basketballs 40 * $9
Which gives us $360.
<h3>
Now let's find the total money needed for sneakers.</h3><h3>
</h3>
The total money needed for sneakers is 7 times the cost of one sneaker.
So, we need to find the cost of 1 sneaker
which is
which gives us,
$18.
Thus total amount of money needed for sneakers is 9 * $18 which gives us
$162
So total amount the coach has to pay is $360+$162 <em>(total cost of basketballs + total cost of sneakers)</em>
=$552
Therefore, total amount the coach has to pay is $552
