200

If the number is divisible by 5, then the last digit should be either 5 or 0.

First digit is fixed.

Second digit can be 10 ways.

Third digit can be 10 ways.

Fourth digit can be 2 ways.

So total number of digits 1 x 10 x 10 x 2 = 200

iragen [17]

Answer:

The correct option is d

Step-by-step explanation:

From the question we are told that

The sample size is n = 64

The mean is $\= x = 320$

The standard deviation is $\sigma = 120$

Generally the standard error of the mean is mathematically represented as

$\sigma_x = \frac{\sigma}{ \sqrt{n} }$

=> $\sigma_x = \frac{120}{ \sqrt{64} }$

=> $\sigma_x =15$

6x+Q=Px+15 what values of P and Q result in an equation with exactly one solution?

NNADVOKAT [17]

P = 6

Q = 15

How to solve:

Note the equal sign. This means that both expression's out come must equal each other. For that to happen, everything inside both expressions must equal each other. In this case:

6x + Q = Px + 15; 6x + 15 = 6x + 15
