Adam tried to compute the average of his 7 test scores. He mistakenly divided the correct sum of all of his test scores by 6, which yielded 84. What is Adam’s correct average test score?

Answers

Answer 1

Answer: Adam got the sum of his grades right, but he divided that correct figure by 6, getting 84 Before that division, the sum of his grades must have been 84 * 6, or 504. He should have divided 504 by 7, getting 72. Answer: His correct average test score is 72.

Which represents a quadratic function?f(x) = −8x3 − 16x2 − 4x

f (x) = x 2 + 2x − 5

f(x) = + 1

f(x) = 0x2 − 9x + 7

A quadratic function is one of the form f(x) = ax^2 + bx + c, where a, b, and c are numbers with a not equal to zero. In the given question, the only function that satisfies the condition of a quadratic function is f(x) = x^2 + 2x - 5 and thus is the correct answer to the question.

Answer:

f (x) = 3/4 x ^2 + 2x − 5

Step-by-step explanation:

Which function has a range of {y|y ≤ 5}?f(x) = (x – 4)^2 + 5

f(x) = –(x – 4)^2 + 5

f(x) = (x – 5)^2 + 4

f(x) = –(x – 5)^2 + 4

basically see the vertices
y=a(x-h)^2+k
(h,k) is vertex

also, when a is negative, graph opens down
when a is positive, graph opens up

y<5
k musbe 5

eliminate last 2

since less than, must open down

Hello,

$((4)/(3))/(2)=(4)/(6)=(2)/(3)$

$((8)/(9))/((4)/(3))=(8*3)/(9*4)=(2)/(3)$

$((16)/(27))/((8)/(9))=(16*9)/(27*8)=(2)/(3)$

The sequence is geometric .
