Answer:

The z-score for an ACT score of 26 is 0.17.

Step-by-step explanation:

Z-score:

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 pvalue, we get the probability that the value of the measure is greater than X.

In a particular year, the mean score on the ACT test was 25 and the standard deviation was 5.9.

This means that [tex]\mu = 25, \sigma = 5.9[/tex]

Find the z-score for an ACT score of 26.

This is Z when X = 26. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{26 - 25}{5.9}[/tex]

[tex]Z = 0.17[/tex]

The z-score for an ACT score of 26 is 0.17.

Answer:

[tex]-\frac{8}{5} = -1\frac{3}{5}[/tex]

Step-by-step explanation:

[tex]1 \frac{4}{5} = \frac{9}{5}[/tex]

[tex]-3 \frac{4}{10} = -\frac{34}{10} = -\frac{17}{5}[/tex]

Multiply the whole number by the denominator and add that to the numerator. I simplified [tex]-\frac{34}{10}[/tex] by dividing by two getting [tex]-\frac{17}{5}[/tex]. Then add [tex]\frac{9}{5}[/tex] and [tex]-\frac{17}{5}[/tex] together. Then put [tex]-\frac{8}{5}[/tex] into a mixed fraction. How many times does 5 go into 8 and what is the remainder? The answer is -1 times and the remainder is 3. The mixed fraction is [tex]-1 \frac{3}{5}[/tex].

The expression 1 4/10 + (-3 4/10 gives the value -1 3/5.

Mixed fractions are type of fractions which consist of a whole number part and a fractional part.

Mixed fractions are of the form a b/c where a is the whole number part and b/c is the fractional part.

Given expression is,

1 4/5 + (-3 4/10)

Since a positive and negative combined, it becomes negative.

Also mixed fractions can be converted into improper fractions.

1 4/5 + (-3 4/10) = 1 4/5 - 3 4/10

                         = [(1 × 5 + 4) / 5] - [(3 × 10 + 4) / 10]

                         = (9 / 5) - (34 / 10)

Making the denominator of first fraction equal by multiplying with 2 on both numerator and denominator,

1 4/5 + (-3 4/10) = [(9 × 2) / (5 × 2)] - [34 / 10]

                         = (18 / 10) - (34 / 10)

                         = -16 / 10

                         = -1 6/10

                         = -1 3/5

Hence the value of the expression is -1 3/5.

Answer: 200

Step-by-step explanation:

174 rounded to the nearest hundred is:

200

When rounding to the nearest hundred, like we did with 174 above, we use the following rules:

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Explanation + answers

Because there are lengths going from 0 to 1, the lines must mean either decimals or fractions (we'll use fractions for this.)

1. There are twelve lines from 0 and 1, which we can use as the denominator for our fraction. This means the length of each line is 1/12.

2. In order to find where K's point is at, we simply need to count until we get to it. After counting, I see that K is on point 8/12, which we can simplify to get a smaller number. If we simplify once, we get 4/6, which we can again simplify to get 2/3. This gives us the answer K is on point 8/12 or 2/3.

Answer:

291.875

Step-by-step explanation:

16 x 291.875= 4670

Given:

Selling price of each CD = $5.00

Cost price of each CD = $1.25

Number of CDs ordered = 300

Profit must be at least $500.

To find:

The number of CDs needs to sell.

Solution:

Let n be the number of CDs needs to sell.

Selling price of each CD = $5.00

Selling price of x CDs = $5n

Cost price of each CD = $1.25

Cost price of 300 CDs = 300×$1.25

                                      = $375

We know that,

[tex]Profit=S.P.-C.P.[/tex]

[tex]Profit=5n-375[/tex]

Profit must be at least $500. it means profit must be greater than or equal to $500.

[tex]5n-375\geq 500[/tex]

[tex]5n\geq 500+375[/tex]

[tex]n\geq \dfrac{875}{5}[/tex]

[tex]n\geq 175[/tex]

All options are incorrect. The required inequality is n is greater than or equal to 175.

Answer:

433333333333

Step-by-step explanation:

The complete arithmetic sequence will be 92, 89, 86, 83, and 80.

Let a₁ be the first term and d be a common difference.

Then the nth term of the arithmetic sequence is given as,

aₙ = a₁ + (n - 1)d

The first term (a₁) is 92 and the fifth term (a₅) is 80.

Then the common difference between the terms will be given as,

a₅ = a₁ + (5 - 1)d

80 = 92 + 4d

-12 = 4d

d = -3

Then the missing terms will be

92, 92 - 3, 92 - 6, 92 - 9, and 92 - 12

92, 89, 86, 83, and 80

Thus, the complete arithmetic sequence will be 92, 89, 86, 83, and 80.
