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:

Elanor's standardized score is 1.19
Gerald's standardized score is 0.72
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

The measures of the legs of a right triangle are 15 m and 20 m. Use the triangle measures and substitute the lengths for a and b

DochEvi [55]

Answer:

Step-by-step explanation:

We can use the Pythagorean theorem to determine the length of the hypotenuse

a^2 + b^2 = c^2

15^2 + 20 ^2 = c^2

225 + 400 = c^2

625 = c^2

Take the square root of each side

sqrt(625) = sqrt(c^2)

25 = c

Write your own two equations that would have a solution of (3, 6).

andrey2020 [161]

Answer:

y = 2x

y = 3x - 3

Step-by-step explanation:

Hi,

y = 2x

6 = 2(3)

6 = 6

That's a solution

y = 3x - 3

6 = 3(3) - 3

6 = 9 - 3

6 = 6

That's a solution

Hope this helps :)

Use the given information to solve for x and y

Anuta_ua [19.1K]

Answer:

x = 10 and y = 7

Step-by-step explanation:

Equalateral triangle means all sides are equal.

x = 10, easy

make y + 3 = 10

y = 7

Easy, no real math needed. lol
