Answer:
its D) x = -8 is correct
All the values less than 7 are included in the number line. The graph on number line is shown in figure attached. In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
-Hops
- We have 52 cards in a deck of cards.
- We have 4 cards of the same number (4 jack, 4 aces...).
Probability of drawing a jack = 4/52
Probability of drawing a jack followed by an ace =(4/52)*(4/52)=0.00592
The mass of lead cylinder is: 859.10 grams
Step-by-step explanation:
In order to find the mass of a cylinder we have to find the volume first
Given
Radius = r = 2 cm
Height = h = 6 cm
The volume of cylinder is given by:
![V = \pi r^2h](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20r%5E2h)
Putting the values
![V = 3.14 * (2)^2 * 6\\= 3.14*4*6\\=75.36\ cm^3](https://tex.z-dn.net/?f=V%20%3D%203.14%20%2A%20%282%29%5E2%20%2A%206%5C%5C%3D%203.14%2A4%2A6%5C%5C%3D75.36%5C%20cm%5E3)
Now,
Density of lead per cm^3 = 11.4g
![Mass\ of\ cylinder = Volume*Density\\= 75.36*11.4\\=859.10\ grams](https://tex.z-dn.net/?f=Mass%5C%20of%5C%20cylinder%20%3D%20Volume%2ADensity%5C%5C%3D%2075.36%2A11.4%5C%5C%3D859.10%5C%20grams)
The mass of lead cylinder is: 859.10 grams
