Answer: A. $725.95

Step-by-step explanation:

First you need to add 129.95 * 5 since they bought 5 plus the delivery cost.

For the first one, the total cost will be:

The cost for the pallets + the cost of delivery.

We know each pallet costs $129.95, thus 5 pallets will cost:

5 * 129.95 = 649.75

$649.75

Adding the delivery of $76.20:

649.75 + 76.20 = 725.95

$725.95

Answer: the total cost is $725.95

For the 2nd one, we have two sides that are equal. 3 squares with the value of x, plus 6 circles each with a value of 1, is the same as 9 circles each with a value of 1.

The total value of the circles on the left is equal to 6, and the total value of the circles on the right is 9. We can say the following:

x + x + x + 6 = 9

If we subtract 6 from both sides, since 6-6 = 0 and 9-6 = 3...

x + x + x = 3

Now we can easily see that the value of x must be 1, as:

1 + 1 + 1 = 3

Answer: x = 1

A lighthouse keeper has a 10 degrees angle of depression between the horizontal light beam and the line of sight from the ship.

Andrei [34K]

107.75m
This is a trigonometric ratio problem. the angle of depression (10) is opposite the height (19m) and the distance is adjacent to the distance (x). opposite ad adjacent sides to the angle is a tangent problem.
$tan \theta = \frac{opp}{adj}$
plus in values, we know.
$tan (10) = \frac{19}{x}$
switch tan(10) and x using the products property.
$x = \frac{19}{tan (10)}$
plug in to calulator to get answer
x=107.75

The difference between the prediction interval and the confidence interval is that A. the prediction interval is narrower than t

Kitty [74]

Answer:

The prediction interval provides an interval estimation for a particular value of y while the confidence interval does it for the expected value of y.

Step-by-step explanation:

A. the prediction interval is narrower than the confidence interval.

the prediction interval is always wider than the confidence interval.

B. the prediction interval provides an interval estimation for the expected value of y while the confidence interval does it for a particular value of y.

False

C. the prediction interval provides an interval estimation for a particular value of y while the confidence interval does it for the expected value of y.

True

D. the confidence interval is wider than the prediction interval.

the prediction interval is wider
