Answer:

n ≥ -17

Step-by-step explanation:

Writing a symbolic inequality, we get:

10 - 3n ≤ 61

Solve this for 3n by adding 3n to both sides of this equation:

10 ≤ 61 + 3n

Solve for n by subtracting 61 from both sides and then dividing all of the resulting terms by 3:

-51 ≤ 3n (divide both sides by 3):

-17 ≤ n, or

n ≥ -17

what is the probability of randomly selecting a score between 1 and 2 standard deviations below the mean?

velikii [3]

Answer:

0.13591.

Step-by-step explanation:

We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.

We know that z-score tells us that a data point is how many standard deviation above or below mean.

To solve our given problem, we need to find area between z-score of -2 and -1 that is $P(-2$ .

We will use formula $P(a$ to solve our given problem.

$P(-2$

Using normal distribution table, we will get:

$P(-2$

Therefore, the probability of randomly selecting a score between 1 and 2 standard deviations below the mean would be 0.13591.

The sum of three consecutive odd numbers is 183. What is the second number in the sequence?

atroni [7]

Answer:

Step-by-step explanation:

If you want only the middle number, then call it x

the largest of the 3 is x + 1

The smallest of the 3 is x - 1

Add

x + 1 + x - 1 + x = 183 Cancel the 1s out.

x + x + x = 183 Combine the like terms on the left

3x = 183 Divide by 3

x = 183/3 Do the division

x = 61

The middle number is 61

Which phrase represents the algebraic expression 3p+6/7p-9

omeli [17]

Answer:

The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine

Step-by-step explanation:

3p = three x a number

7p = seven x a number

3p+6 = sum of three x a number plus six

7p-9 = difference of seven x the number minus nine

(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine
