Answer:
49.865%
Step-by-step explanation:
Given that:
μ = 4 ; σ = 1
For x = 4
P(x < 4) :
Z score (x - μ) / σ
P(x < 7) - P(x < 4)
((7 - 4) / 1) - ((4 - 4) / 1)
P(Z < 3) - P(Z < 0)
Usibg the Z probability calculator :
0.99865 - 0.5
= 0.49865
= 0.49865 * 100
= 49.865%
252 will most likely support it because if you simplify 30 over 50 then u get 3 over 5, then 5 divided by 420 is 84. If you multiply 84 by 3 then you get 252

Answer:
solution (-∞,4.25)
Step-by-step explanation:
Given inequality is
.
Now we need to solve the given inequality. Describe the solution set using the set-builder or interval notation. Then, graph the solution set on a number line.





Hence solution set using interval notation is given by (-∞,4.25).
Graph will be an arrow pointing to the left of 4.25
