Simon drove through some roadworks where the speed limit was 50 mph. Two cameras recorded the time taken to travel 1200 m throug

Tom [10]

Answer:

$Speed = 21.43m/s$

Step-by-step explanation:

Given

$Distance = 1200m$ -- of the roadworks

$Time\ Recorded = 56s$

Required

Determine the speed

In this case:

$Speed = \frac{Distance\ of\ Roadword}{Time\ Captured}$

$Speed = \frac{1200m}{56s}$

<em></em> $Speed = 21.43m/s$ <em> --- approximated</em>

Solve the equation for x. 2x2 − 72 = 0 Enter you solution in set notation.

CaHeK987 [17]

Answer:

The set of solution is {-6,6}

Step-by-step explanation:

That means 2x^2-72=0?

If yes, here the solution for this:

x^2-36=0 (divise both sides by 2)

x^2=36

x^2=6^2

We have x=6 or x= - 6

The set of solution is {-6,6}.

Hope that useful for you.

The figure above shows the probability density function for the random variable x. What is P(3≤x<7)?

qwelly [4]

The value of the probability P(3≤x<7) is 1

<h3>How to evaluate the probability expression?</h3>

The expression is given as: P(3≤x<7)

This is calculated using:

P(3 ≤ x < 7) = P(3) + P(4) + P(5) + P(6)

Using the figure of the probability density function (see attachment), we have:

P(3 ≤ x < 7) = 0.30 + 0.30 + 0.20 + 0.20

Evaluate

P(3 ≤ x < 7) = 1

Hence, the value of the expression is 1
