A high-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. Suppose that the radius

lord [1]

The increase of the radius is a linear increase since we have the constant rate of 0.07 inches per second

The equation for a linear growth/decay is given by the form $y=mx+c$ where $m$ is the rate of increase and $c$ is the value of $y$ when $x=0$

We have
$m = 0.07$
$c=36$ when $t=0$

So the equation is $r=0.07t+36$

The length of the radius when $t=400$ seconds is
$r=0.07(400)+36$
$r=64$ inches

Classify the following random variables as discrete or continuous: X: the number of automobile accidents per year in Virginia. Y

Bess [88]

Answer:

X: Discrete random variable

Y: Continuous random variable

M: Continuous random variable

N: Discrete random variable

P: Discrete random variable

Q: Continuous random variable

Step-by-step explanation:

A discrete random variable is a variable that takes countable values such as 0,1,2,3, etc. A continuous random variable is a variable that takes measurable values such as 0.1,1.3,2.6,3.8, etc.

X,N and P are discrete random variables because they have countable values such that Number of automobile accidents,number of eggs laid and number of building permits can be counted as 0,1,2,3, and so on.

Y,M and Q are continuous random variables because they don't have countable values such that the length of time to play,the amount of milk produced and the weight of grain can be measured but can't be counted.

Annual Social Security benefit = 0.42 x $37,991 = $15,956.22
Annual bills = $1,755 x 12 = $21,060
Outstanding annual bill to be settled after using the Social Security benefit = $21,060 - $15,956.22 = $5,103.78
Monthly supplementary money needed = $5,103.78/12 = $425.32

In a circle, a chord of 50 cm bisects a chord of 40 cm. Find the length of the longer segment of the 50 cm chord.

Andreyy89

Answer:

<u>The length of the longer segment of the 50 cm chord = 40</u>

Step-by-step explanation:

let the length of the longer segment of the 50 cm chord = x

so, the other segment = 50 - x

A chord of 50 cm bisects a chord of 40 cm

using the Intersecting Chords Theorem

so, x(50-x) = 20 * 20

50x - x² = 400

x² - 50x + 400 = 0

(x - 40)(x - 10) = 0

x = 40 or x = 10

<u>So, the the length of the longer segment of the 50 cm chord = 40</u>
