Answer:

The speed of marble is 1.5 m/s

Step-by-step explanation:

Consider the graph shown below.

As we know: speed=\frac{Distance}{Time}

To find the speed we need to substitute the value of distance and time by using the graph shown below.

From the graph we know when time was 0s marble covers a distance of 0 m.

When time was 2s marble covers a distance of 3 m.

Now substitute the value of distance and time in above formula.

speed=\frac{3}{2}

speed=1.5

Hence, the speed of marble is 1.5 m/s

It is known that 10% of the calculators shipped from a particular factory are defective. What is the probability that exactly th
IRINA_888 [86]

Answer:0.0081  or 0.81%

Step-by-step explanation:

The required probability is P(3,5,0.1)= C5 3 * p^3*q^2, where

C5 3=  5!/3/2=4*5/2=10

p is the probability that one randomly selected calculator is defective= 10%=0.1

q is the probability that one randomly selected calculator is non-defective.

q=1-p=1-0.1=0.9

So P(3,5,0.1)= 10*0.1^3*0.9^2=0.01*0.81=0.0081

Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.
inysia [295]
<h2>Hello!</h2><h2>Let me help you.</h2>

As I understand, you need to write an equation that relates t \ and \ y. This problem will be solved using equations. The problem states:

<em>Nick bought t candies and divided them equally between his y friends and me. Each of us got 7 candies.</em>

<em />

From this statement, we know that:

t: Number of candies Nick bought.

y: Number of friends.

Since I am included in this problem, the number of people involved here can be expressed as:

y+1

Since each of us got 7 candies, then it is true that:

\frac{t}{y+1}=7 \\ \\ t=7(y+1)

<em>So t (number of candies) is a function of y(number of friends).</em>
