Answer:

the answer would be C) square root of 250 units

Step-by-step explanation:

5x5=25 and 15x15=225 you would then add them together and get 250 and the reason why it isnt 250 units is  because to find the hypotenuse you would need to find the square root of 250! Hope this helps! :3

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?
Karolina [17]
270 minutes = 4,5 hours = 4 hours and 30 minutes
60 minutes = 1 hour

63 miles per 270 minutes
x miles per 1 hour = 60 minutes

\dfrac{63[miles]}{x[miles]} = \dfrac{270[minutes]}{60[minutes]}

63 \cdot 60 = 270x
3780 = 270x\quad |:270
x=14[miles]

His average speed is 14 miles per hour.

Vlad1618 [11]

Answer:

The critical region for α= 0.05 is Z > ± 1.645

The calculated value of Z= 1.100

Step-by-step explanation:

The null and alternate hypotheses are given

H0: μ ≤ 43

H1: μ > 43  one tail test

∝= 0.05

n= 29

Standard Deviation= s= 4.1

Mean = μ0 = 44

For one tail test the z value of α= ± 1.645

The critical region for α= 0.05 is Z > ± 1.645

The test statistic is given by

z=μ0-μ/ s/√n

Z= 44-43/4.1/√29

Z= 1/4.1/√29

Z= 1.100

Since the calculated value Z= 1.100 does not  fall in the critical region , We reject H0 and may conclude that the mean number of calls per salesperson per week is not more than 43

When building the Channel, the English and French each started drilling on opposite sides of the English Channel. The two sectio
Alekssandra [29.7K]

Suppose the English could drill the Channel in 6.2 years, then they drill with speed \dfrac{L}{6.2} km per year, where L is the length of the English Channel. If the French could drill in 5.8 years, then their speed of drillling is \dfrac{L}{5.8} km per year.

Together their speed will be

\dfrac{L}{6.2} +\dfrac{L}{5.8} =\dfrac{5.8L+6.2L}{6.2\cdot 5.8}=\dfrac{12L}{35.96}=\dfrac{3L}{8.99}.

If they drill together, they will spend

\dfrac{L}{\frac{3L}{8.99}} =\dfrac{8.99}{3}=2.9966666....\approx 3 years.

Answer: it would have taken nearly 3 years.
