Answer:
She will thin she has 96 extra dollars.
Step-by-step explanation:
Since she recorded it as a credit she thinks that she added that to her account, and let´s say that in her account she had $100, now she has to pay $48, so in reality she has $100-$48=52, so she actually has $52 in her account, but in her checkbook she has that she had $100 and added$48, so she will have: $100+$48=$148, that a $96 deficit from her actual account to her checkbook.
Answer:
a) (x, y) = (1, 7)
Step-by-step explanation:
Let be the following system of inequalties:
We can find the right option by evaluating each option in the system of inequalities:
a) (x, y) = (1, 7)
Then,
(TRUE)
(FALSE)
(1, 7) is not a solution of the system of inequalities.
b) (x, y) = (1, -7)
Then,
(TRUE)
(TRUE)
(1, -7) is a solution of the system of inequalities.
c) (x, y) = (1, -5)
Then,
(TRUE)
(TRUE)
(1, -5) is a solution of the system of inequalities.
d) (x, y) = (-1, 6)
Then,
(TRUE)
(TRUE)
(-1, 6) is a solution of the system of inequalties.
Therefore, we conclude that correct answer is A.
Answer:
Null hypothesis would be:
C. The true proportion of residents who have recently had the flu is 0.05.
Alternative hypothesis would be:
E. The true proportion of residents who have recently had the flu is greater than 0.05.
Step-by-step explanation:
Hypothesis testing is made to estimate the true population proportion<em> using the sample info. </em>
The purpose is to provide sufficient evidence to support that the true proportion of people who have recently had the flu is greater than 0.05. Therefore null and alternative hypotheses use this proportion.
Answer:
See below:
Step-by-step explanation:
So first, Paul has a number that he got before he multiplied it, we can call that 
, and for his answer after doubling it. we'll call it 
.
So with this information, we know that 
so we can use that to make an equation.
We can solve it by first dividing on both sides and getting our answer.
Cheers! We get our final answer of 6.55.
