Answer:

1.a. 5(x-6)

2.d=k-9

3.c.10 x+5

4.c.The quotient of some number and six.

5.a.The quotient of three times some number and five

6.b.x^5

Step-by-step explanation:

1.We are given that verbal expression ''five times the difference of a number and six''

We have to find its algebraic expression

Let x be the number

Difference of x and 6=x-6

We are multiplying  difference of x and 6 by 5

Then we get

5(x-6)

Option a is true

2.Verbal expression ''nine less than some number ''

Let k be the some number

Nine less than some number k

=k-9

Option d is true.

3.Five more than the product of ten and some number .

Let x be the some number

Product of 10 and some number x

Then we get 10 x

Now, 5 more than the product of 10 and x

Then, we get an algebraic expression

10 x+5

Hence, option c is true.

4.Given algebraic expression

Fraction with variable x in numerator and 6  in  the denominator .

We have to find its verbal expression

The quotient of some number and six.

Hence, option c is true.

5.We are given that an algebraic expression

3x\div5

We have to find its verbal expression

The quotient of three times some number and five

Where x is some number in algebraic expression.

Hence, option a is true.

6.We are given that verbal expression

''Some number to the power of 5''

We have to find the algebraic expression

Let x  be the some number

Then , the algebraic expression

x^5

Hence, option b is true.

A fish story: The mean length of one-year-old spotted flounder, in millimeters, is 127 with standard deviation of 22, and the me
pishuonlain [190]

Answer:

The z-score for this length is of 1.27.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

One-year-old flounder:

Mean of 127 with standard deviation of 22, which means that \mu = 127, \sigma = 22

Anna caught a one-year-old flounder that was 155 millimeters in length. What is the z-score for this length

This is Z when X = 155. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{155 - 127}{22}

Z = 1.27

The z-score for this length is of 1.27.
