Answer:
The third and fourth options.
Step-by-step explanation:
You simplify the inequality first...
-6x + 15 < 10 - 5x
-x < -5
x > 5
The first option is incorrect since it is less than.
The second option is basically -5x < 15; x > -3; that's incorrect.
The third option is basically -x < -5; x > 5; that is correct!
The fourth option is correct since it shows more than 5.
The fifth option is incorrect because it shows less than -5.
Hope this helps!
Answer:
f(x) = 0 on x= -1 and x = -2
Step-by-step explanation:
Given function is:
In order to find the value of x on which the function will have value zero we have to factorize the function and find zeroes of the function. The method used will be factorization of polynomial as the function is in polynomial form.
So,
To find the zeroes, putting the function = 0
Hence,
f(x) = 0 on x= -1 and x = -2
Answer:
0.84134
Step-by-step explanation:
Given that:
Mean, m = 70
Standard deviation, s = 10
P(x ≥ 60)
Obtain the standardized score (Zscore) :
Z = (x - m) / s
Z = (60 - 70) / 10
Z = - 10 / 10
Zscore = - 1
P(Z ≥ 1) = 0.84134 (Z probability calculator)
