Answer: Option 'd' is correct.
Step-by-step explanation:
Since we have given that
Margin of error = 0.5 years
Standard deviation = 5
At 90% confidence, z = 1.645
We need to find the minimum size of the sample they must take.
So,
Hence, Option 'd' is correct.
First you need to solve for x by subtracting 9 from both sides (-3x less than/equal to 6), then dividing the inequality by -3, which would also flip the sign, so to speak. now you would have x is greater than/ equal to -2. now you would draw a circle above -2, fill it in since it is equal to, and draw the arrow going toward 0 (I think)
I believe the answer should be C
Answer: CP = Rs 78.667
Step-by-step explanation:
The data given to us are
Selling price = Rs. 118
Profit percentage = 50
Now using the form formula
CP = ( SP * 100 ) / ( 100 + percentage profit).
Where;
Cp is cost price and Sp is selling price
So we input our numbers
CP = ( 118 × 100 ) / ( 100 + 50)
CP = 11800 / 150
CP = Rs 78.667
Answer:
We have to multiply P(A) and P(B) which is 0.0045 * 0.01 * 100 (to make it a percentage) = 0.0045%.
