A professor graded the final exams and found that the mean score was 70 points. Which of the following can you conclude?
larisa86 [58]

Answer:  C) 50% of the students scored below 70%

<u>Step-by-step explanation:</u>

Mean is the average.  To find the mean (aka average) you add up all of the scores and divide by the number of tests.  

B) The mean can be 70 without any test scoring 70% so B is not true.

A) Since B is not true, then A is not a valid option.

D) We don't know any of the other data so don't know if it is skewed left, skewed right, or normal.  Therefore, option D is not true.

C) If the average is 70%, then half received grades above that score and half received grades below that score.  So, option C is TRUE!

Josephine solved a quadratic equation. Her work is shown below.
mariarad [96]

Answer:

Step-by-step explanation:

hello :

5(x + 7)² = 245

(x + 7)² = 49

x=0 is solution but you have other solution -14 because :(-14+7)² = (-7)² =49

here is an solution Step-by-step :

(x + 7)² = 49  means : (x + 7)² = 7²

(x + 7)² - 7²=0   use identity : a²-b² = (a-b)(a+b)

a=x+7  and b= 7

(x+7-7)(x+7+7) = 0

x(x+14)=0

x=0 or x+14=0

so : x=0 or x= -14

mars1129 [50]

The factored expression ofx^3 - 7x^2 -5x +35 is (x^2 - 5)(x - 7)

<h3>What is an expression?</h3>

An expression is an algebraic term used for a mathematical statement that includes addition subtraction multiplication and division

x^3 – 7x^2 – 5x + 35

factor the given equation

x^2(x – 7) – 5(x - 7)

Factor out x - 7

(x^2 - 5)(x - 7)

Therefore, the factored expression is (x^2 - 5)(x - 7)
