Hi there!
Answer:
The answer is "<span>Subtract 10, then divide by −4"
Explanation:
To solve a linear equation (for x) we need to isolate the variable (x). First we need to bring the variables to the left side (in this case, it is already on the correct place). Next up is bringing all the integers to the right side. Therefore, we must first subtract 10. Our final step is dividing by the number that is placed in front of x (in this case divide by </span><span>−4)
</span><span>
Solving the equation:
</span><span>−4x + 10 = 2
First subtract 10 (from both sides of the equation)
</span>−4x = −8
Divide by −4
x = −8 / −4 = 2
Therefore, the solution is x = 2
I hope this anwer helps you!
Answer:
c. One sided t-test
Step-by-step explanation:
One sided t test because we want to compare two means and alternative hypothesis is directional.
It’s supposed to be (5,9) both numbers positive
