Answer: y= 66
Step-by-step explanation: Well first you would do +7 on both sides and then it would be Y/6=4+7, then you would multiply 6 on both sides which then you would have y=24+42 which simplified it would be y=66
Expand: (x+5)(x+5)
Multiply: (x^2)(10x)(25)
Distrib. Prop: the same as line before
Multiply: (x^3)(5x^2)(10x^2)(50x)(25x)(125)
Answer:
A.
Step-by-step explanation:
124 * 11 = 1364
1364 + 328 = 1,692
Answer:
1245
Step-by-step explanation:
-Given the standard deviation is $9000 and the margin of error is $500.
-the minimum sample size at a 95% confidence level can be calculated using the formula:
Hence, the minimum sample size is 1245
*Since there's no data fromw which we are drawing our variables, we can manually input our parameters in excel and calculate as attached.
10ax - 5ay + 2bx - by
=10ax + 2bx - 5ay - by
=2x(5a + b ) - y(5a + b )
=(2x - y )(5a +b)
