There was a great deal of publicity a few years ago about allegationes that gravel companies delivered less gravel tian contacts demanded. After a lengthy investigation, the cily managers concluded that
the allegations were unfounded. However, they also claimed that it was too expensive to measure
every load and were forced to rely upon the bonesty of the catrictor! Having successfully
completed an introductory statisties course and having been just hired by the city, you point out that it
is not necessary to weigh every truck; why not just weigh a sample? Your survisor is not convinced
and asks for a demonstration
A current contract for a 1 kilometer stretch of road requires gravel till for a width of 10 meters and
a depth of 1 meter The successful bidder estimated it will take 500 tandem-track loads of gravel. The
total amount of gravel required is 10,000 m' So the moun volume of gravel in the 500 trucks must be
at least 20 m.

no, because the sides are not congruent

d

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
