Probabilities are less than or equal to one.
Probability indicates how often something happens. If probability is 1, it happens every time. It cannot go over 1.

Probabilities are <u>less than or equal to one.</u> (option B)

<u>Explanation</u> :-

<em>Probability </em><em>m</em><em>e</em><em>a</em><em>n</em><em>s</em><em> </em><em>the chances of occurrence of an event. If there are 100% chances of its occurence then the probability for that </em><em>event</em><em> will be 1, and if there are no chances then it will be 0. </em><em>I</em><em>f chances are undefined, then probability will lie between 0 and 1, but it will never go beyond 0 and above 1.</em>

<u>Formula for calculating probability</u> :-

P(E) = No. of outcomes/Total no. of

outcomes.

Hope it helps!

Jess borrows 250 from the bank. The band chargEs 11% simple interest over 2 years.
Inessa [10]

Answer:

$305

Step-by-step explanation:

You have to use the following formula to calculate the accrued amount:

A=P(1 + rt), where:

A= accrued amount

P= principal amount= $250

r= rate of interest= 11%

t= time period= 2 years

Now, you have to replace the values in the formula:

A=250*(1+0.11*2)

A=250*(1+0.22)

A=250*1.22

A=305

According to this, at the end of 2 years, Jess owes the bank $305.

Find the distance from A(-8,-3,-2) and B(-4,8,0) , find ||AB||
RUDIKE [14]

Answer:

||AB|| = 11.8743

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, (x_1,y_1,z_1) and (x_2,y_2,z_2). The distance between them is given by:

D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}

Distance from A(-8,-3,-2) and B(-4,8,0)

||AB|| = \sqrt{(-4-(-8))^2+(8-(-3))^2+(0-(-2))^2}

||AB|| = \sqrt{4^2 + 11^2 + 2^2}

||AB|| = 11.8743

What is the recursive rule for the following sequence: -9, -2, 5, 12, ….
tino4ka555 [31]

Answer:

The answer is option (C)=an-1+7

Step-by-step explanation:

A recursive rule is a formula that in which each term is expressed as a function of its preceding term(s), meaning in order to get to the nth term you have to express it in a form of the term that comes before it. In our case the a(n-1) term

So for the sequence -9, -2, 5, 12

The nth term is any number on the sequence and

  • -2 is the a(n-1) term for -9
  • 5 is the a(n-1) term for -2
  • 12 is the a(n-1) term for 5

So we need to find out what we have to do to the preceding term to get the next.

To get -2 from -9 we have to add 7 to -9; -9+7=-2

To get 5 from -2 we have to add 7 to -2; -2+7=5

To get 12 from 5 we add 7 to 5; 7+5=12

So the recursive rule would be= a n-1+7

What is 2/9 + 1/9 + 1/6 in fraction form
Nikitich [7]
We get all these to have the same denominators for all the fractions.

2*2/9*2 = 4/18
1*2/9*2 = 2/18
1*3/6*3 = 3/18

Now we can add all the numerators.

4/18 + 2/18 + 3/18 = 9/18

Simplify our answer by dividing both numbers by 3, then by 2.

9/3 and 18/3 = 3/6= 1/2

Our final answer is 1/2
