Identify least to greatest 4/25 .15 7% .28

IRISSAK [1]

Answer:

7%, .15, 4/25, .28

Step-by-step explanation:

7% is 0.07 because it mean per hundred. .15 is next because when you divide 4/25 you get 0.16 so yeah then 4/25 is third then .28 is last because it is the greatest.

A vehicle arriving at an intersection can turn right, turn left, or continue straight ahead. The experiment consists of observin

Temka [501]

Answer:

a) Sample space (S) = {TR, TL, Cs}

b) Pr(Vehicle Turns) = 2/3.

Step-by-step explanation:

a) By sample space (S) we mean the list all possible outcome of an event. From the illustration in the question, only three (3) outcome is possible:

i) Vehicle Turn Right (TR)

ii) Vehicle Turn Left (TL)

iii) Continue Straight ahead (Cs)

And since the experiment consists of observing the movement of a single vehicle through the intersection, then, the sample space (S) is:

==> {TR, TL, Cs}

b) Since we are assuming that all sample points are equally likely, it imply that they have equal probability of occurring. And by probability:

Pr(TR) = 1/3

Pr(TL) = 1/3

Pr(Cs) = 1/3

Meanwhile, the question wants us to find the probability that the vehicle turns. This means, the vehicle turning either right or left. Thus;

Pr(vehicle turns) = Pr(TR) or Pr(TL) = Pr(TR) + Pr(TL)

Pr(vehicle turns) = (1/3) + (1/3) = 2/3

Quadratic formula. pls help

crimeas [40]

Answer:

$x=-1,\frac{5}{7}$

Step-by-step explanation:

1) Split the second term in $7{x}^{2}+2x-5$ into two terms.

1 - Multiply the coefficient of the first term by the constant term.

$7\times -5=-35$

2 - Ask: Which two numbers add up to 2 and multiply to -35?

7 and -5.

3 - Split 2x as the sum of 7x and -5x.

$7x^2+7x-5x-5$

2) Factor out common terms in the first two terms, then in the last two terms.

$7x(x+1)-5(x+1)=0$

3) Factor out the common term x+1.

$(x+1)(7x-5)=0$

4) Solve for x.

1 - Ask: When will (x+1)(7x-5) equal zero?

When x + 1 0 or 7x-5=0

2 - Solve each of the 2 equations above.

$x=-1,\frac{5}{7}$
