2 1/2 + x = 3 1/2

3 1/2 - 2 1/2= 1

x = 1

A random variable x is uniformly distributed between 45 and 150: to 4 decimal places, what is the probability that x = 48?

klio [65]

It appears that the distribution in question may be a continuous uniform distribution. In that case there is an infinite number of possible values between 45 and 150. Therefore the probability that x is exactly 48 is zero.

Use set notation to write the members of the following set, or state that the set has no members

mars1129 [50]

Answer:

Odd numbers that are multiple of 5 and are in between 22 and 66 are-

25, 35, 45, 55, 65

Let this set be represented by A

A= {25, 35, 45, 55, 65}

the above form represents the set in its roster form

Find the x and y intercepts.

Roman55 [17]

-3/4x + 5/6 y = 15

Multiply through by 6

-9/2x + 5y = 90

Add 9/2x to both sides

5y = 90 + 9/2x

Divide both sides by 5

y = 18 + 9/10x

y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c

Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. The equation for the ball’s height, h,

zhenek [66]

Answer:

Therefore,

The ball strike the ground at time , t = 6 s

Step-by-step explanation:

Given:

The equation for the ball’s height, h, at time t seconds is

$h=-4.9t^{2}+19.6t+58.8$

To Find:

time, t = ? (When the ball strike the ground)

Solution:

When the ball strike the ground height, h will be ZERO,

So put h = 0 in above given equation for time,

$0=-4.9t^{2}+19.6t+58.8$

Which is a Quadratic Equation

Dividing throughout by - 4.9 we get

$0=t^{2}-4t-12$

On Factorizing, splitting the middle term we get

$t^{2}-6t+4t-12=0$

$t(t-6)+2(t-6)=0\\\\(t+2)(t-6)=0\\\\t=-2\ or\ t=6$

As time cannot be negative,

t = 6 s

Therefore,

The ball strike the ground at time , t = 6 s

Can you form a right triangle with the three lengths given? Why or why not? 4mi, 5mi, 6mi

Vladimir [108]

A right triangle must satisfy this equation: a^2 + b^2 = c^2

a= shortest length
b=medium length
c=the longest length

a triangle with sides 4,5,6 will satisfy not this equation because:
4^2 + 5^2 ≠ 6^2
16+25 = 41

41 ≠ 36

so the answer is C.

Hope this helps.
