There are 10 vehicles in a parking lot: 3 suvs and 7 trucks. what is the probability that of any 7 randomly chosen vehicles, exactly 1 is an suv? a. 0.142 b. 0.175 c. 0. 333 d. 0.428

B. 0.175

Step-by-step explanation:

We are given that,

Total number of vehicles = 10

Number of SUV = 3

Number of trucks = 7

Probability to select any random 7 vehicles out of 100 is .

It is required to select exactly 1 SUV.

Thus, we have, out of the 7 vehicles, exactly 1 is a SUV and other 6 are trucks.

So, the probability of selecting exactly 1 SUV is

i.e. Required probability =

i.e.  Required probability =

i.e.  Required probability =

i.e.  Required probability = 0.175

Hence, the probability to randomly select exactly 1 SUV from 7 vehicles is 0.175

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
