4n-3=4n-2 subtract 4n from both sides
-3=-2
Since -3!=-2, there is no solution.
So your answer is a.
The diameter of a circle is 16 kilometers. Then the area of the circle is
<u>Solution:</u>
Given that , the diameter of a circle is 16 kilometers
We have to find the area of the circle .
Radius is half of diameter.
<em><u>The area of circle is given as:</u></em>
Hence, the area of the circle is 201.062
For the selection to be 10, there has to be at least 3 girls. So there's a 1/4 chance of 3 girls picked, 1/4 4 girls, 1/4 5 girls and 1/4 6 girls. Because the sum of people has to be 10, if 4 girls are picked, to make 10 people there is a 1/1 chance of 6 boys. 1/4 * 1/1 = 1/4. So 1/4 chance of 4 girls and 6 boys
Answer:
45 degrees
Step-by-step explanation:
All triangles equal 180 degrees so your just add the two existing angles which gets you 135 then you do 180-135, therefore giving you 45
Answer:
651.
Step-by-step explanation:
Note: In the given series it should be -29 instead of 29 because 29 cannot be a term of AP whose first term is 91 and common difference is -6.
Consider the given series is
It is the sum of an AP. Here,
First term = 91
Common difference = 85 - 91 = -6
Last term = -29
nth term of an AP is
where, a is first term and d is common difference.
Sum of AP is
Therefore, the sum of given series is 651.
