Answer:
√85
Step-by-step explanation:
for this, you will probably need to draw a graph. Plot the points, and then you will notice that you can draw a triangle with one side being the x-axis ( go on to (-6,0) then drop down unitll you hit the point (-6;-7)
// use the pythagoream theorem to find the length
the distance of the leg on the x-axis is 6 (calculate 0-(-6))
the distance of the leg that is dropping down is -7 (calculate 0-(-7))
then we have 2 legs and need to find the hypotenuse.
Pythagorean theorem a^2 + b^2 = c^2
substitute :
6^2 + 7^2 = c^2
36+49 = 85
c= √85
50% because there are two possible answers. Your probability of guessing it correctly is 1 out of 2, which is one half. 50%
Any score between 76 and 84 will be 1 deviation from the mean.
To figure this out you subtract 4 from 80 (80-4 = 76) and you add 4 to 80 (80+4) = 84 and that tells you that most of the scores will fall between 76 and 84 which is 1 deviation from the mean.
Idk what the answer is but dab if u see this
Answer:
24
Explanation:
(23+32)-(3×4)-(52-5)+(7×4)
(55)-(12)-(47)+(28)
- 55-12=43
- -47+28= -19
- 43-19=24
