Write a linear equation y=mx + b to represent the graph:

Mathematics
1 answer:
RUDIKE [14]3 years ago
8 0

Step-by-step explanation:

Firstly you need to understand some variables in the equation.

m= gradient

b= where the line cuts the y axis

Now we can try using any coordinate in the graph and see what the question becomes.

at a point where :

Y= -2 and X= 1

The equation becomes

-2=m(1)+-5

Then:

-2+5=m

m=3

So, we can now write the equation in the form of y=mx+b as follow.

Y=3x-5

In the spinner below, what is true about the probability of landing on 3 and the probability of landing on 4?
Karo-lina-s [1.5K]

Answer:

C.The probabilities are equal.  

The above statement is the only TRUE statement.

Step-by-step explanation:

Here, the given number of total possibilities are { 0,1,2,3,4,5,6,7,8,9}

So, number of total outcomes = 10

Let E : Event of spinner landing on 3

and E' : Even of spinner landing on 4

{Probability of Event E}  =  \frac{\textrm{Total number of favorable outcomes}}{\textrm{Toatl outcomes}}

\implies P(E) = \frac{1}{10}

⇒ P( landing on 3 ) = 1/10

and  P(E') = \frac{1}{10}

P( landing on 4 ) = 1/10

Now, the given statements are

A.The probability of landing on 3 is less than  probability of landing on 4.

FALSE, as both the probabilities are equal to 1/10.

B.The probability of landing on 3 is greater than probability of landing on 4.

FALSE, as both have same probabilities.

C.The probabilities are equal.

TRUE, both have same probability = 1/10

D.The probabilities cannot be predicted

FALSE, the probability are predictable.
