Answer:

The given statement is true.

Step-by-step explanation:

The given statement is true.

The correlation between two variables is +0.98.

  • Coefficient of correlation measure linear relation between two variables.
  • The positive coefficient of correlation tells that with increase in one variable leads to increase in other variables.

Thus, a positive correlation of 0.98 means that the two variables have a strong relationship and with increase in one variable, the other variable increases.

In circle P diameter QS measures 30 cm.
kow [346]

<u>Given</u>:

The diameter of the circle P is 30 cm.

The radius of the circle P is 15 cm.

The measure of ∠RPS is 125°

We need to determine the arc length of QR.

<u>Measure of ∠QPR:</u>

The angles QPR and RPS are linear pairs.

Thus, we have;

\angle QPR + \angle RPS=180^{\circ}

Substituting the values, we have;

\angle QPR + 125^{\circ}=180^{\circ}

          \angle QPR =55^{\circ}

Thus, the measure of ∠QPR is 55°

<u>Arc length of QR:</u>

The arc length of QR can be determined using the formula,

Arc \ length =(\frac{\theta}{360})2 \pi r

Substituting \theta=55 and r =15, we get;

Arc \ length =(\frac{55}{360})2 (3.14)(15)

Arc\  length = \frac{5181}{360}

Arc \ length =14.4 \ cm

Thus, the arc length of QR is 14.4 cm.

Hence, Option d is the correct answer.
