Answer:
77.1107
Step-by-step explanation:
for an approximate result, divide the mass value by 2.205
hopefully this help's
Answer:
0.7938
Step-by-step explanation:
z1 = (125-100)/15 = 1.667
P( < 125) = 0.9522
z2 = (85-100)/15 = -1
P( > 85) = 0.8413
0.9522 + 0.8413 - 1 = 0.7935
Answer:
1. Fill in the box with 1
2. Fill in the box with -2
Step-by-step explanation:
Expression:
![(-2x^3 + [\ ]x)(x^{[\ ]}+1.5) = A](https://tex.z-dn.net/?f=%28-2x%5E3%20%2B%20%5B%5C%20%5Dx%29%28x%5E%7B%5B%5C%20%5D%7D%2B1.5%29%20%3D%20A)
Solving (1): Fill in the box to make it a polynomial.
To make it a polynomial, we simply fill in the box with a positive integer (say 1)
Fill in the box with 1
![(-2x^3 + [1]x)(x^{[1]}+1.5) = A](https://tex.z-dn.net/?f=%28-2x%5E3%20%2B%20%5B1%5Dx%29%28x%5E%7B%5B1%5D%7D%2B1.5%29%20%3D%20A)

The above expression is a polynomial.
This will work for any positive integer filled in the box
Solving (2): Fill in the box to make it not a polynomial.
The powers of a polynomial are greater than or equal to 0.
So, when the boxes are filled with a negative integer (say -2), the expression will cease to be a polynomial
Fill in the box with -2
![(-2x^3 + [-2]x)(x^{[-2]}+1.5) = A](https://tex.z-dn.net/?f=%28-2x%5E3%20%2B%20%5B-2%5Dx%29%28x%5E%7B%5B-2%5D%7D%2B1.5%29%20%3D%20A)

Notice that the least power of x is -1.
Hence, this is not a polynomial.
The number of adult tickets and children tickets sold were 92 and 220 respectively
What differentiate adult tickets from children's
The adult tickets can be represented by a while children's ticket is c
The total number of tickets sold which is 312 means the sum of a and c
a+c=312
Total value of adult tickets=a*12
total value of children tickets=c*5
12a+5c=2204
Solve for a in the first equation
a=312-c
substitute for a in the second equation
12a+5c=2204
12(312-c)+5c=2204
3744-12c+5c=2203
3744-2203=12c-5c
1541=7c
c=1541/7
c=220
a=312-220
a=92
