Answer:

Step-by-step explanation:

Time taken for task 1:

Distance= 750m= 0.75 km

Speed= 10 km/hr

Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec

Time taken for task 2:

t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec

Time taken for task 3:

t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec

Total time took:

T1 +T2+T3= 40 mins and 30 second (approximately)

Answer:

D) 35 yards for $90.

Step-by-step explanation:

We have been given four options and we are asked to choose the option that represents the best deal.

Let us find the cost of per yard cloth for our given choices.

A. $\text{ Price offered by option A}=\frac{\$20}{5\text{ yards}}$

$\text{ Price offered by option A}=\frac{\$4}{\text{ yard}}$

Therefore, option A offers $4 per yard of cloth.

B. $\text{ Price offered by option B}=\frac{\$30}{10\text{ yards}}$

$\text{ Price offered by option B}=\frac{\$3}{\text{ yard}}$

Therefore, option B offers $3 per yard of cloth.

C. $\text{ Price offered by option C}=\frac{\$55}{20\text{ yards}}$

$\text{ Price offered by option C}=\frac{\$2.75}{\text{ yards}}$

Therefore, option C offers $2.75 per yard of cloth.

D. $\text{ Price offered by option D}=\frac{\$90}{35\text{ yards}}$

$\text{ Price offered by option D}=\frac{\$2.57}{\text{ yard}}$

Therefore, option D offers $2.57 per yard of cloth.

Since price offered by option D is less than other option D is the best deal.

Kay [80]

The z-score of the number of teens that transfered schools is the standard score

The obtained value of z is 5

<h3>How to determine the value of z?</h3>

The given parameters are:

Population mean, μ = 50
Population standard deviation, σ = 10
Sample, x = 100
Sample mean = 59

The z-value is calculated using:

z = (x - μ)/σ

Substitute known values in the above formula

z = (100 - 50)/10

Evaluate the difference

z = 50/10

Evaluate the quotient

z = 5

Hence, the obtained value of z is 5
