After 3000 impressions, ad A has a CTR of 2% and a conversion rate of 25%, and ad B has a CTR of 4% and a conversion rate of 10%
leva [86]

Answer: A

Step-by-step explanation:

3000 impressions

A CTR 2%    conversion 25%

2% of 3000 = 2/100 . 3000 = 60 clicks

25% of 60 = 25/100 . 60 = 15

B CTR 4%    conversion 10%

4% of 3000 = 4/100 . 3000 = 120 clicks

10% of 60 = 10/100 . 120 = 12

This way, A converted more than B

Identify the reference angle
ser-zykov [4K]

Answer:

Below in bold.

Step-by-step explanation:

300 degrees - reference angle is |360 - 300 |= 60 degrees

225 = 225 - 180 = 45 degrees

480 = 480 - 360 = 120 so it is 180 - 120 = 60 degrees.

-210 = |-210 + 180| = 30 degrees.

If the measure of arc GH= 90° and the measure of arc EF= 45°, calculate m∠GDH.
user100 [1]

Answer:

∠ GDH = 67.5°

Step-by-step explanation:

The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.

∠ GDH = \frac{1}{2}(GH + EF) = \frac{1}{2} (90 + 45)° = 0.5 × 135° = 67.5°
