Answer:

consistent independent

Step-by-step explanation:

x+y = -4 y = -x -4

y = 2x-1

The equations do not have the same slope , so they are not the same line

therefore the are not dependent

If they do not have the same slope, they cannot be parallel and cannot be inconsistent

The two lines must be consistent independent

14x+10y=72 14x+4y=96 Solve the following system of equations using any method

Anarel [89]

  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)

Identify the type of hypothesis test below. H0:X=10.2, Ha:X>10.2 Select the correct answer below: The hypothesis test is two-

Ganezh [65]

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.

A sporting goods store charges $27 for 3 basketballs and $90 for 5 boxes of sneakers. A coach orders 40 basketballs and 7 boxes

ValentinkaMS [17]

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, $\frac{27}{3}$ 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 $\frac{90}{5}$ 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
