Answer:

The t distribution can be used when finding a confidence interval for the population mean whenever the sample size is small.

Hence, the correct option is A.

To estimate the population mean we use a t-distribution to calculate the confidence interval. When we use a t-distribution the sample standard deviation is used to estimate the population standard deviation

Factor the expression using the GCF 75m+85
Sloan [31]

General Idea:

To find the Greatest Common Factor of binomial, we need to write each term as product of prime factors. GCF by definition means the product of common prime factors involved with its lowest terms. It is a number which will go in to both the terms in a binomial.

Given :

75m + 85

Applying the concept :

75m=3 \; \times \; 5^2 \; \times m\\\\85=5 \; \times \; 17\\\\GCF\; of\; 75m + 85 \;is\; 5

In order to get the expression inside the parenthesis after factoring GCF 5, we need to divide each term by what we factor out as shown below:

75m+85=5( \frac{75m}{5}  + \frac{85}{5}  )=5(15m+17)

Larry Thomas's charge account statement shows an unpaid balance of $800. The monthly finance charge is 1.5% of the unpaid balanc
lilavasa [31]

Answer:

The new account balance is <u>$812</u>.

Step-by-step explanation:

Given:

Larry Thomas's charge account statement shows an unpaid balance of $800.

The monthly finance charge is 1.5% of the unpaid balance.

Now, to find the new account balance.

Unpaid balance = $800.

Monthly finance charge of the unpaid balance = 1.5%.

Now, to get the new account balance:

$800 + 1.5% of $800.

=800+\frac{1.5}{100} \times 800.

=800+0.015\times 800.

=800+12.

=\$812.

Therefore, the new account balance is $812.
