Answer:

P(A) represents the probability that an adult has blue eyes.

$P(A^c)$ represents the probability that an adult does not have blue eyes.

Step-by-step explanation:

Given the event:

A: an adult has blue eyes

The complement of a set is another set that contains all the elements that are not in the original set.

Hence, the event $A^c$ must be:

$A^c$ : an adult does not have blue eyes

So P(A) represents the probability that an adult has blue eyes and $P(A^c)$ represents the probability that an adult does not have blue eyes.

AC = 2.87

Solution:

Given AB = 5

To find the length of AC:

The given triangle is a right triangle.

So we can use trigonometric formula.

$$\sin \theta=\frac{\text { Opposite }}{\text { Hypotenuse }}$

$$\Rightarrow \sin B=\frac{A C}{AB }$

$$\Rightarrow \sin 35^\circ=\frac{AC}{5 }$

$$\Rightarrow \sin 35^\circ\times 5=AC$

$$\Rightarrow 0.573\times 5=AC$

$$\Rightarrow 2.865=AC$

⇒ AC = 2.87

Hence the length of AC = 2.87.

While filling a pool 144centimeters deep, Fiona notices it has taken 2 hours to fill it up to a depth of 36 centimeters. 1a At w

Aneli [31]

Answer:

Rate at which pool is getting filled $0.18$ m/hr

Step-by-step explanation:

Given

Depth up to which the pool gets filled in two hours is equal to $36$ centimeter

As we know

One meter $= 100$ centimeter

So $36$ centimeter is equal to $0.36$ meter

Rate at which pool is getting filled is equal to height up to which water is filled in 2 hours divided by time taken

Rate at which pool is getting filled $\frac{0.36}{2} = 0.18$ m/hr

The price to ship a box varies directly as the weight of the box in pounds. A box that weighs 10 pounds costs $10.90 to ship.

nydimaria [60]

Well we can say 10.90/10 = the cost per pound to ship the item
we can infer this from the above text so
10.90/10 = 1.09.
So 1.09 * 37 = 40.33
$40.33
or 40 dollars and 33 cents to ship the second box with a weight of 37lb (pounds).
