You can use normalCdf(.72,.78,.75,.01) to find the answer or if you standardize your numbers (z scores) normalCdf(-3,3,0,1).
Answer:
7,228,202%
Step-by-step explanation:
Population at first census in 1979 was 3929
If the Population had increased to 284,000,000 by 2000, the population increase will be;
284,000,000-3929
= 283,996,071
%increase in population = increment/initial population×100%
= 283,996,071/3929×100%
= 7,228,202%
This means that the population has increased by 7,228,202%
Answer:
D. x ≤ -18
Step-by-step explanation:
-x/6 ≥ 3
Multiply both sides by 6.
-x ≥ 3 × 6
-x ≥ 18
Multiply both sides by -1 and reverse the inequality.
x ≤ 18 × -1
x ≤ -18
Answer:
There is a solution. Here's how:
Step-by-step explanation:
So, you work out the problem, and you lay it out here:
5-4+7+1=5-4+7x+1.
First, you start by subtracting 5 from both sides, which cancels both of the 5s. Here's your equation now:
-4+7+1=-4+7x+1
Next, you add 4 to both sides, which makes you identify the identity.
Here's your equation now:
7+1=7x+1
Now, you subtract 1 from both sides.
Here's your equation now:
7=7x
Finally, divide both sides by 7, while identifying the identity.
x=1.
Answer: large pizza
Work:
1) You can determine the arc of a slice that is 1/12 of the whole pizza using the diameter.
2) First, calculate the total circumference of each pizza.
Formula for the circumference: 2π×radius
radius = diameter / 2
medium pizza: 2π (12 / 2) = 12π ≈ 37.70 in
large pizza: 2π (16/2) = 16π ≈ 50.27 in
3) arc of a 1/12 sector
arc of a 1/12 sector = circumferece × 1/12
medium pizza: 37.70 in / 12 = 3.14 in
large pizza: 50.27 in / 12 = 4.19 ↔ this is pretty close to 4.25
So, at the end we have found that the sector of 4.25 in left belongs to a large pizza.
