Answer and Step-by-step explanation:
Let's solve your equation step-by-step.
−2x−4=−4x+3
Step 1: Add 4x to both sides.
−2x−4+4x=−4x+3+4x
2x−4=3
Step 2: Add 4 to both sides.
2x−4+4=3+4
2x=7
Step 3: Divide both sides by 2.
2x/2 =7/2
So x is
7/2
In the hypothesis, based on the 90% confidence interval, (0.02, 0.12), there is convincing evidence that the new formula of laundry detergent is better because the interval is entirely above 0
<h3>How to illustrate the information?</h3>
Let's define the null hypothesis and alternative hypothesis first.
H0:p1-p2=0
Ha:p1-p2>0
Also, 90% CI is (0.02,0.12), we know that if the 0 of the null hypothesis is not in the confidence interval then we reject the null hypothesis.
In the given scenario 0 is not within the given interval, hence we reject the null hypothesis and accept the claim that new detergent A cleans better.

Answer:
Step-by-step explanation:
The blue section is a right triangle. Use the Pythagorean Theorem to find the hypotenuse.
base of right triangle = 6 cm
height of right triangle = 8 cm
hypotenuse = √(6²+8²) = √100 = 10 cm
