Answer:
No, none of the number need to be 48 for the mean to be 48. To get a mean, you add up all the number and divide it by the amount of numbers.
Example:
the mean of 10, 79, 42, 88, 19, and 50 is 48, but the actual number 48 was not part of the set.
10 + 79 + 42 + 88 + 19 + 50 = 288
288 ÷ 6 = 48
When you have two squares stacked on top of each other, pretend the angle in the bottom left of the top square is a 90 degree angle, that means that the angle of the square right underneath, also sharing the line, is a 90 degree angle. Or whatever you would need to get it equal to 180, my example was 90/90.
Answer:
Astronomers directly use geometry in their work rather than accountants , judges, pharmacist and politicians.
They used geometry to measure velocity , direction, distance, relativity, momentum, and probability. They used it to look at objects in the sky with a telescope by setting a required angle to get a proper view .
But Accountants, judges, pharmacist and politicians are not in use of geometry directly or frequently.
Hence, Option 'B' is correct.
Step-by-step explanation:
Just combine like terms: all of the x^2 together, all of the x's together and all of the numbers:
3x2+5x2+5x-2-1
8x2+5x-3 simplified, so letter A
Answer:
b = 14
Step-by-step explanation:
9 + (5-b) = 0
9 + 5 - b = 0
14 - b = 0
+ b = + b
14= b
