The addition equation to represent Jackson's net change in money is x + (-y) = 4.63
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register.
WE need to Write an addition equation to represent Jackson's net change in money.
Given that :
The change received = 4.63
The Net change in money :
Let initial amount before purchase is represented by x
The Cost of item purchased = y (negative as it is incurred)
The Net change in money:
Initial amount + cost of item purchased = change received
x + (-y) = 4.63
Therefore, an addition equation to represent Jackson's net change in money is x + (-y) = 4.63

Answer:
x = -1
Step-by-step explanation:
8x + 16 = 8
8x = 8 - 16
8x = -8
x = 8/-8
x = -1
Answer:
From this finding, it can be said that the sample proportion is greater than the population proportion because the test statistic (z = 2.45) is positive.
Step-by-step explanation:
H0: p = 0.35
Ha: p > 0.35
The test is a one-tailed test because the alternate hypothesis is expressed using greater than.
The test statistic (z) for a proportion is given as (p' - p) ÷ sqrt [p(1-p)/n]
p' is sample proportion
p is population proportion
n is sample size
For the test statistic z to be positive, p' must be greater than p.
