Answer: Elisa
Step-by-step explanation:
Since Elisa withdrew $23 at a time from her bank account and withdrew a total of $207, the number of times that Elisa withdrew will be:
= $207/$23
= 9 times
Since Frances withdrew $43 at a time from his bank account and withdrew a total of $172, the number of times that Frances withdrew will be:
= $172/$43
= 4 times.
Based on the calculations, we can see that Elisa made the greater number of withdrawal.
Answer:
Step-by-step explanation:
circumference of the circle, C=2*3.14*r
C=31.4
31.4=2*3.14*r
r=31.4/(2*3.14)=5
The answer is -3^15
You start with the brackets and (3^2x3^3) =3^5. Now we have -(3^5) ^3. Because the is one expoente out of the brackets and one in you multiple the exponent (3x5=15) and you distribute the negative sign you get -3^15. Hope this helps!
Agree.
By mathematical terms, a line stretches on in either direction for an infinite amount of points, something that is not measurable in the real world. Everything we loosely call 'lines' that we may spot, are in fact line segments. Take for instance the blue lines on a sheet of notebook paper. We may refer to them as lines but since they do have endpoints, they are line segments.
Part (a)
The raw score is x = 25. The mean and standard deviation are mu = 45 and sigma = 13.8 respectively.
The z score is computed with the formula below
z = (x-mu)/sigma
z = (25-45)/13.8
z = -1.449275 approximately
z = -1.45 is the final answer
========================================================
Part (b)
We want the z score to be larger than 2. So z > 2.
This is the same as wanting the expression (x-mu)/sigma to be larger than 2
(x-mu)/sigma > 2
(x-45)/13.8 > 2
x-45 > 2*13.8
x-45 > 27.6
x > 27.6+45
x > 72.6
If a customer's age is greater than 72.6 years, then this means they have a z score greater than 2. We can say they are more than 2 standard deviations above the mean.
If you need a whole number, then I'd round up to 73. Or you could pick any age larger than this.
