is the answer because if you take the games won and lost this is what you get
Step-by-step explanation:
The foundational concept of algebra is to use the alphabetical letters to find the unknown number.
Algebra is the concept that uses the alphabetical letters such as x, y, z, etc. to calculate the unknow numbers. here the letters are also called as variables. The values that are known in the expression as termed as constants.
The general operations performed on the algebra is
- Addition = x + y
- Subtraction = x - y
- Multiplication = x * y
- Division = x / y
Here the alphabets x and y are called variables.
Order of operations:
The order of operation in algebra is given as follows
- Perform all the operations inside the brackets
- Perform the operations on roots and exponents
- Perform all the division and multiplication operations moving from left to right
- Perform all the addition and subtraction operations from left to right.

Answer:
0.025 ;
(-0.7198 ; 0.7698)
Step-by-step explanation:
From the table :
_____________ private schls ___ public schls
Sample size, n _____ 80 __________ 520
P, NBC teachers ___ 0.175 ________ 0.150
P1 = P of private school teachers
P2 = P of public school teachers
Difference in proportion :
P1 - P12 = 0.175 - 0.150.= 0.025
The 90% confidence interval for 2 - sample proportion :
C.I = (p1-p2) ± [Zcritical * √(p1(1-p1)/n1 + (p2(1-p2)/n2)]
Zcritical at 90% = 1.645
C.I = 0.025 ± [1.645 * √((0.175*0.825)/80 + (0.150*0.850)/520)]
C.I = 0.025 ± [1.645 * √(0.0018046875 + 0.0002451)]
C.I = 0.025 ± 1.645 * 0.0452755
C.I = 0.025 ± 0.07448
C.I = (-0.7198 ; 0.7698)
The amount that you should be willing to rent an additional oven when the order size is 1 dozen cookies is the amount that is less than the profit of producing those cookies.
<h3 /><h3>What amount should be paid to rent an additional oven?</h3>
The dozen cookies that Kristen’s Cookie Company are about to make are an additional order which means that they do not have the ovens to make it.
They will therefore have to rent an additional oven. If they did this, the amount they pay for the additional oven should not give them losses. They should therefore rent the oven at a cost that is less than the profit they will get for the additional 1 dozen cookies.
