Answer:
non linear
Step-by-step explanation:
linear means a straight line graph. This type is quadratic since it has a parabola.
Answer:
Step-by-step explanation:
z value of 14.9 = (16.3 - 14.9) / 2
= 0.7
= .7580
z value of 12.9 = (16.3 - 12.9) / 2
= 1.7
=.9554
Required probability = .9554 - .7580
= .1974
or 19.74 % .
Answer:
630
Step-by-step explanation:
10 times 21= 210÷2= 105
35×21=735-105=630
The factored form for this question is (5x-1)(x-5)
Okay so...
x² = 5x + 24 move it, so one side equals zero.
x² - 5x - 24 =0 factors of 24 is 3 and 8 when you subtract 8 from 3 you get -5.
(x+3)(x-8)
x+3= 0 or x-8=0
x= -3 or x=8
b. 2x² - 5x + 1=0
quadratic formula = -b +-√b²-4ac / 2a
a= 2 b= -5 c=1
-(-5) +-√(-5)² - 4(2)(1) / 2(2)
5+-√25 - 8 / 4
=5 +- √17 / 4
x= 5/4 + √17 / 4 or x= 5/4 - √17/4
i couldn't find the plus-minus sign that why there's (+-)
i hope this helps! :)
