Step-by-step explanation:
3 - 8 = x^3 + x
Answer:
There is sufficient evidence. A further explanation is provided below.
Step-by-step explanation:
According to the question,
The alternative as well as null hypothesis will be:
![H_0:\mu = 16](https://tex.z-dn.net/?f=H_0%3A%5Cmu%20%3D%2016)
![H_a:\mu>16](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3E16)
The test statistics will be:
⇒ ![z = \frac{\frac{\bar x - \mu}{\sigma} }{\sqrt{n} }](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B%5Cfrac%7B%5Cbar%20x%20-%20%5Cmu%7D%7B%5Csigma%7D%20%7D%7B%5Csqrt%7Bn%7D%20%7D)
By putting the values, we get
⇒ ![=\frac{\frac{16.06-16}{0.24} }{\sqrt{96} }](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B16.06-16%7D%7B0.24%7D%20%7D%7B%5Csqrt%7B96%7D%20%7D)
⇒ ![=\frac{\frac{0.06}{0.24} }{\sqrt{96} }](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Cfrac%7B0.06%7D%7B0.24%7D%20%7D%7B%5Csqrt%7B96%7D%20%7D)
⇒ ![=2.45](https://tex.z-dn.net/?f=%3D2.45)
Or,
The p-value will be:
= 0.0071
i.e.,
⇒ ![p-value< \alpha](https://tex.z-dn.net/?f=p-value%3C%20%5Calpha)
Thus the above is the correct answer.
Answer:
30 square millimeters
Step-by-step explanation:
3 x 3 = 9
3 x 1 = 3
there are two sides with the area 9 therefore...
9 x 2 = 18
There are four sides with the area 3 therefore...
3 x 4 = 12
Therefore the suface area is
12 + 18 = 30
Answer:(Fog)(-6)=29
Step-by-step explanation:
(fog)=-3(2x+2)-1
=-6x-6-1
=-6x-7
(fog)(-6)= -6(-6)-7
=36-7
=29
Answer:
The new can can hold upto volume of 476.69 cubic centimeters.
Step-by-step explanation:
Diameter of the can = d = 6 cm
Radius of the can = r = 0.5d = 0.5 × 6 cm = 3 cm
Height of the can = h = 12 cm
Company wants to increase the dimensions of their cans by a multiple of 1.12. So, the new dimension will be:
r'= 3 cm × 1.12 = 3.36 cm
h' = 12 cm × 1.12 =13.44 cm
Volume of the = can = V
Volume of a cylinder = ![\pi r^2h](https://tex.z-dn.net/?f=%5Cpi%20r%5E2h)
![V=\pi r'^2h'](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%27%5E2h%27)
![=3.14\times (3.36 cm)^2\times 13.44 cm=476.6808 cm^3\approx 476.68 cm^3](https://tex.z-dn.net/?f=%3D3.14%5Ctimes%20%283.36%20cm%29%5E2%5Ctimes%2013.44%20cm%3D476.6808%20cm%5E3%5Capprox%20476.68%20cm%5E3)
The new can can hold upto volume of 476.69 cubic centimeters.
