Point (a,a) lies on the graph of the equation 3y = 2x -4 find the value of a

Igoryamba

Substituting (x, y) with (a, a), since we have:

3a=2a-4, which means that 3a-2a=-4, that is a=-4.

So, the point is (-4, -4).

Remark: a point which lies in the graph of an equation is a solution of that equation. So x=a, y=a satisfies the equation 3y = 2x -4, which makes our substitution legitimate.

Answer: (-4, -4).

Answer:

The calculated t-value is t=0.47.

Step-by-step explanation:

The question is incomplete:

"Americans typically eat quickly and do not spend time enjoying their meal. A researcher plans to test if those trained in mindfulness will take more time to enjoy their meal (that is, they will spend more time eating than the general population). The general population spends an average of 68 minutes per day combined eating their three meals. The researcher trains a sample of 16 individuals in mindfulness and then collects data on how long they spend eating per day. The sample mean for those trained in mindfulness equals 74; the SS = 150. What is the calculated t-value? Round your answer to two decimal places."

The degrees of freedom are (n-1)=(16-1)=15

The standard deviation is:

$s=\sqrt{\frac{SS}{n-1}}=\sqrt{\frac{150}{16-1}}=\sqrt{10}=3.16$
