<u>Answer:</u>

<u>ii) £120</u>

<u>iii) £2,400</u>

<u>a) 10 workers</u>

<u>c) 4 workers more to be employed.</u>

<u>Step-by-step explanation:</u>

ii) To find the buying price we deduct 20% (percent) from the selling price of £150.

= 20/100 x 150

= £30 (Next we substract this value from the selling price of £150) = €150 - £30 = £120

iii) A 12% interest per annum Implies a 12 percent of the borrowed amount of 20,000, which is calculated as

12% or 12/100 x 20,000 = £2,400

a) Put simply, we create an equation for the problem.

4 men * 10 days = 40 man days.

X men * 4 days = 40 man days.

Let's substitute the equation:

(X/ 4) * (4/ 10) = 40 / 40

(X/4) * 0.4= 1 (collect like terms)

0.4 * x = 4

0.4x/0.4= 4/0.4

x = 10 workers.

(c) 4 extra workers to would need to be employed since we have six already available (10-6=4).

scores on the act college entrance exam follow a bell-shaped distribution with mean 18 and standard deviation 6. Wayne's standar
WITCHER [35]

Answer:

His actual score is 15

Step-by-step explanation:

Here, we are interested in calculating Wayne’s actual score on the ACT

when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.

Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.

The formula for the z-score or standard score is given below;

z-score = (x - mean)/SD

where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6

So, substituting these values into the z-score equation, we have;

-0.5 = (x-18)/6

x-18 = 6(-0.5)

x -18 = -3

x = -3 + 18

x = 15
