I need help with this. Both Standard Deviation and the Mean. Both have answer choices of Decrease, Increase, or stay the same.

almond37 [142]

Answer:

The mean will stay the same.

The standard deviation will decrease.

Step-by-step explanation:

For the 5 cards, she has received, the mean will be:

μ=(∑x)/n

=125/5

=25

The mean is 25 and the standard deviation is 10.

σ=10

If a new card is received with $25, then the sum will be $150

So the new mean will be:

μ'=(∑x)/n

=150/6

=25

And the new standard deviation will be:

σ'= 9.12

We can clearly see that

μ= μ'

and

σ> σ'

So the mean will remain the same and standard deviation will decrease. .

15 is at least the quotient of a number and 6 increased by 3

crimeas [40]

Answer:

The number is $x\geq 72$

Step-by-step explanation:

Given:

Quotient $\geq$ 15

Let the number be $x$

The quotient is 15 of a number and 6 which is increaase by 3

Hence forming the inequality expression from the question given we get;

$\frac{x}{6}+3\geq 15$

Now Solving the above equation we get,

$\frac{x}{6}+3\geq 15\\\\\frac{x}{6}\geq 15-3\\\\\frac{x}{6}\geq 12\\\\x\geq 12\times6\\x\geq 72$

Hence the number is $x\geq 72$
