Answer:

6.63 \leq \mu_D \leq 9.15

For this case since the confidence interval not contains the value 0 we can conclude that we have a significant effect in terms of the loss weight since the confidence interval just show positive values, this conclusion can be made at a significance of 5%

Step-by-step explanation:

For this case we know that the confidence interval for the weight loss program is given by:

6.63 \leq \mu_D \leq 9.15

For this case since the confidence interval not contains the value 0 we can conclude that we have a significant effect in terms of the loss weight since the confidence interval just show positive values, this conclusion can be made at a significance of 5%

Please help me with this question​

Applying the formula for the area of a sector and length of an arc, the value of k is calculated as: 27.

<h3>What is the Area of a Sector?</h3>

Area of a sector of a circle = ∅/360 × πr²

<h3>What is the Length of an Arc?</h3>

Length of arc = ∅/360 × 2πr

Given the following:

  • Radius (r) = 9 cm
  • Length of arc = 6π cm
  • Area of sector = kπ cm²

Find ∅ of the sector using the formula for length of acr:

∅/360 × 2πr = 6π

Plug in the value of r

∅/360 × 2π(9) = 6π

∅/360 × 18π = 6π

Divide both sides by 18π

∅/360 = 6π/18π

∅/360 = 1/3

Multiply both sides by 360

∅ = 1/3 × 360

∅ = 120°

Find the area of the sector:

Area = ∅/360 × πr² = 120/360 × π(9²)

Area = 1/3 × π81

Area = 27π

Therefore, the value of k is 27.

Answer:

  • y-intercept: 2000
  • rate of change: 500

Step-by-step explanation:

When Timon starts, he is already $2000 in debt. If we represent Timon's debt with positive numbers, the y-intercept will be $2000.

Timon's debt seems to be increasing at the rate of $500 per month. That value is the rate of change.

After m months, Timon's debt d will be ...

  d = 500m + 2000
