Answer: Loss = Rs. 416
Step-by-step explanation:
Since CP is more than SP, it is a loss.
Loss = CP - SP
Loss = 9000 - 8584
Loss = 416
Step-by-step explanation:
Longest side of cuboid: 7cm
Height of cylinder:
2 × 7 = 14 cm
Volume of cuboid:
7x3x4=84![cm^3](https://tex.z-dn.net/?f=cm%5E3)
Volume of cylinder:
![84=14\pi r^2 \\r=\sqrt{\frac{6}{\pi} } \ \ \ cm\\r=1.38 \ cm\\](https://tex.z-dn.net/?f=84%3D14%5Cpi%20r%5E2%20%5C%5Cr%3D%5Csqrt%7B%5Cfrac%7B6%7D%7B%5Cpi%7D%20%7D%20%20%5C%20%5C%20%5C%20%20cm%5C%5Cr%3D1.38%20%5C%20cm%5C%5C)
Surface area of the cylinder:

<h3>
Answer: D. Kira used published data that is quantitative.</h3>
The published data refers to the government census info being published online. She did not do an observational study because she didn't go to each household herself (rather let the census workers do that task).
The data is quantitative because she is looking at the number of people living in homes in her city. Quantitative data is simply dealing with quantities or numbers. Contrast this with qualitative data that talks about something like color choice.
Answer:
Option C is correct
P(A or B) = 0.65
Step-by-step explanation:
<u>Given:
</u>
P(A) =0.5
P(B)=0.30
P(A and B) =0.15
( The probability of the happening of both independent events will be there product) P( A and B ) =P(A).P(B)
<u>Solution:</u>
To find the probability of the Happening of event A either event B we will use the following formula
P(A or B) = P(A) + P(B)-P(A and B)
= 0.5 + 0.3 - 0.15
=0.65
