Keeli was asked to approximate the square root of 38 to the nearest whole number.

1 answer:

4 0

We know that 36<38<64

so sqrt36 < sqrt 38 < sqrt 64 it is equivalent to 6< sqrt38 < 8

since 38 is closer to 36 than it is to 64, so 6 is <span>approximate the square root of 38 as a whole number</span>

Ace Truck leases its 10-ft box truck at $30/day and $0.50/mi, whereas Acme Truck leases a similar truck at $25/day and $0.55/mi.

Answer:

Ace Truck

$C(m) = 30 + 0.5*m$

Acme Truck

$C(m) = 25 + 0.55*m$

Step-by-step explanation:

The cost function to lease a box truck from a company has the following format:

$C(m) = F + a*m$

In which F is the fixed cost and a is the cost per mile m.

(a) Find the daily cost of leasing from each company as a function of the number of miles driven.

Ace Truck

$30/day and $0.50/mi. This means that $F = 30, a = 0.50$ . So

$C(m) = 30 + 0.5*m$

Acme Truck

$25/day and $0.55/mi. This means that $F = 25 a = 0.55$ . So

$C(m) = 25 + 0.55*m$

Hypergeometric Distribution is the probability distribution of a hypergeometric random variable.

The hypergeometric distribution is used to calculate the statistical importance of having drawn a specific k successes (out of n total draws) from the aforementioned population in the hypergeometric test uses.
