The scientific notation of 0.25 is 2.5 x 10⁻¹
Scientific notation is used to handle numbers that are very big or very small.
It has 3 parts, the coefficient, the base and the exponent.
There must be 1 digit before the decimal point in the coefficient.
10 is always the base
the exponent signifies the number of places the decimal has moved from its original location to the location before 1 digit. Positive exponent signifies that the decimal point is shifted to the right. Negative exponent signifies that the decimal point is shifted to the left.
In the above scientific notationl
2. 5 is the coefficient
10 is the base
-1 is the exponent. the decimal point shifted one place to the left.
Answer:
0.75 days (im a bit unsure but i tried my best, hope this helps :) )
Step-by-step explanation:
If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.
8: 560
x: 525
x= 7.5 (which is considered 7)
Then, find how long it takes to sample 525 samples, when 560 are done in 36 hours;
560: 36
525: x
x= 33.75 (which is considered 34 hours)
The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator
8; 34
15; x
it will become
15:34
8: x
x= 18 hours
Divide by 24 for days hence 0.75 days
Answer:
Part A: When the temperature increases, the number of ice cream cones sold increases. It shows close to a linear relationship.
Part B: y = 2x+5
Step-by-step explanation:
Part A: When the temperature increases, the number of ice cream cones sold increases. It shows close to a linear relationship.
Part B: To write the line of best fit, use the points that run a line through the data.
You can connect (0,5) and (25,55) and have a line through the middle of the data.
This line intercepts the y-axis at (0,5) so b=5.
It's slope is

The slope is 2 and b=5 so y = 2x + 5.
