Hi there!

9 + 1/2 (7n - 26) - 8n
= 9 + 7n*1/2 - 26*1/2 - 8n
= 9 + 3.5n - 13 - 8n
= 9 - 13 + 3.5n - 8n
= -4 + 11.5n

Hope this helps!

Mia's checking account balance is overdrawn by $52.65.

Svetach [21]

Answer:

A

Step-by-step explanation:

So to start, Mia has an account that is overdrawn by $52.65 so her account is negative 52.65. She then adds 135.50 and used 24.30 so you would add 135.50 and 24.30 respectively. This would be (-52.65) + (132.50) - (24.30). This then would get you $58.55

murzikaleks [220]

Answer:

1.20

Step-by-step explanation:

Let mean be represented by M and standard deviation by d. The score will be x and sample number of games be n

To get the test statistic, t for Fernanda's test, we use the formula

$t=\frac {M-x}{\frac{s}{\sqrt n}}$

Substituting 156 for mean, M then 150 for score x and 30 for standard deviation while 36 for n then

$t=\frac {156-150}{\frac{30}{\sqrt 36}}$

t=1.20 when put in two decimal place
