Answer:
or the fourth answer
Step-by-step explanation:
Apply the rule
to rewrite the exponentiation as a radical.
![5\sqrt[4]{x^1}](https://tex.z-dn.net/?f=5%5Csqrt%5B4%5D%7Bx%5E1%7D)
Anything raised to 1 is the base itself.
Answer = ![5\sqrt[4]{x}](https://tex.z-dn.net/?f=5%5Csqrt%5B4%5D%7Bx%7D)
Plz mark me brainliest, hope this helps.
Answer:
C.
Step-by-step explanation:
> is a dotted line and the area above it is shaded
< is a dotted line and the area below it is shades
≥ is solid line with the area above shaded
≤ is a solid line with the area below it shaded
The graph shows characteristics of ≥, and C is the only answer with ≥ in it
A) profit/original price x100 =percentage profit
(Profit: 360-300=$60)
=60/300 x100
=20%
b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720
Profit without discount: 720-600= $120
120-100= $20 discount
20/720 x100 =2.78%
Answer:
d. 20
Step-by-step explanation:
Standard deviation is 4.5
Margin error for the problem is 2 hours
Probability 95%, that means that the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
2 = 1.96 * 4.5/ √n
2 = 8.82/√n
√n = 8.82/2
√n = 4.41
n = 4.41^2
n = 19.44 ≈ 20
