Answer:
the second picture
Step-by-step explanation:
The number is 5. All you have to do is make an equation based on the information you have, x will represent the missing number so, x to the power of 10 divided by x to the power of 7 is equal to 125, then solve.
Answer:
Variance, Range, Standard deviation, Inter-quartile range
Step-by-step explanation:
The most commonly used measure of variability in a data set include;
Variance and standard deviation - measures the variability of a data set about a fixed location, the mean. Variance is the square of the standard deviation.
Range - this is the difference between the largest and the smallest values in a data set.
Inter-quartile range is simply the difference between the third and the first quartile where the second quartile is the median.
Other measures include;
Downside semi-variance
Answer:
for x >0
f(x)=5^x
f(1) = 5^1 = 5
f(2) = 5^2 = 25
f(3) = 5^3 = 125
f(4) = 5^4 = 625
Step-by-step explanation:
Step-by-step explanation:
Here's the first question and how to solve the second.
So the first business start with 250, that's your b in slope.
y = mx + b
y = mx + 250
Now, they charge 14 an hour so that's your m.
y = 14x + 250
x is the number of hours it takes.
The second business is straight up 22 per hour, so it's just y = mx, where b is 0.
y = 22x VS y = 14x + 250
Try plugging in different numbers and seeing how much it take to level out!
