Levart [38]

Answer:

a. 5.26

Step-by-step explanation:

As, the standard deviation of the distribution of the difference between mean is 0.76 so the t score will be simply calculated by dividing the difference of means by standard deviation of the distribution of the difference between mean as hypothesized difference is zero.

t score=Xbar A- Xbar B/Sd of difference of means

t score=55-51/0.76

t score=4/0.76=5.26

X^2 - 25 = 25 solve for x

Nezavi [6.7K]

Answer:

$\tt x=\pm5\sqrt{2}$

Step-by-step explanation:

$\tt x^2 - 25 = 25$

$\tt x^2-25+25=25+25$ (Add 25 to both sides)

$\tt x^2=50$ ( Take square of both sides)

$\tt x=x=\sqrt{50},\:x=-\sqrt{50}$

$\tt x=\pm5\sqrt{2}$

Bianka has a credit line of $8,000. She had a previous balance of $567.91 and made a payment of

Artyom0805 [142]

Answer: $\$ 6371.12$

Step-by-step explanation:

We have the following data:

Bianka's credit line = $8,000

Bianka's previous balance = $567.91

Payments = $1,200

Total purchases = $986.79

Finance charge = $10.00

Well, firstly we have to find Bianka's current balance, which is her previous balance minus all her payments, purchases and charges:

Bianka's current balance = Bianka's previous balance - (Payments + Total purchases + Finance charge)

Bianka's current balance = $567.91 - ($1,200 + $986.79 + $10.00)

Bianka's current balance = -$1628.88

Now we can find her available credit, which is her credit line with the addition of the calculated current balance:

Bianka's available credit = Bianka's credit line + Bianka's current balance

Bianka's available credit = $8,000 + (-$1628.88)

<u>Finally we have:</u>

Bianka's available credit = $6371.12
