Eleanor scores 680 on the mathematics part of the SAT. The distribution of SAT math scores in recent years has been Normal with
Katen [24]

Answer:

  1. Elanor's standardized score is  1.19
  2. Gerald's standardized score is 0.72
  3. Elanor has higher score

Step-by-step explanation:

To compare Elanor's and Gerald's math scores, we need to standardize them and calculate their z-scores.

z score can be calculated using the formula

z=\frac{X-M}{s} where

  • X is the student's score
  • M is the mean score of the exam
  • s is the standard deviation of the exam

Elanor's standardized score is:

z(e) = \frac{680-554}{106} ≈ 1.19

Gerald's standardized score is:

z(g)= \frac{27-24.7}{3.2} ≈ 0.72

Since z(e) > z(g), Elanor has higher score

I NEED HELP WILL MARK BRAINLIEST!!!!!
Luden [163]

Answer:

The volume of cylinder is calculated by:

V = base area x height = pi x radius^2 x height

=>  3617.28 = 3.14 x 12^2 x height

=> 3617.28 = 452.16 x height

=> height = 3617.28/452.16 = 8 (cm)

Hope this helps!

angles X and Y are supplementary and the mesure of angle X is 24 degrees greater than the measure of angle Y. Find the measures
BartSMP [9]

Measures of angles are X = 102° and Y = 78°

Step-by-step explanation:

  • Step 1: Let ∠X = 24 + Y. As they are supplementary angles, ∠X + ∠Y = 180°

⇒ 24 + Y + Y = 180

⇒ 2Y = 180 - 24 = 156

⇒ Y = 156/2 = 78°

  • Step 2: Find measure of X

⇒ X = 24 + Y = 24 + 78 = 102°
