A six-sided number cube is tossed and a coin is flipped.

1 answer:

4 0

4/6 numbers are greater than 2
1/2 chance of flipping heads
Multiply the two fractions together to get the probability
1/2*4/6=2/6=1/3
1/3 probability

KINNDAAAA need help. Will give Brainly! Need the full equation pls!

Alexxandr [17]

Hey, I’m pretty sure the answer is y=1/2x + 0.

To explain, we can plug the x value into the equation for all of the x values, and we will get our y value.

So the first one,

y=1/2(1) + 0 —> 1/2

The second one,

y=1/2(2) + 0 —> 1

And so forth, the rest of the equations will be correct. I hope that helps ! :D

Answers for the 2 boxes please:)

Answer:

(5,-5)

Step-by-step explanation:

Eliminate y-term

$(2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5$

We can eliminate x-term but for this system of equations, eliminating y-term is faster.

Substitute x = 5 in any given equations.

I will choose to substitute in the first equation.

$2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5$

Answer Check

Substitute both x-value and y-value in any given equations

$2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25$

The equation is true. (It is better to check both the answer for both equation.)

Thus the answer is (5,-5)

Midtown barber shop conducts 112 haircuts per day. assume each barber works 8 hours per day and take the same amount of time to

goblinko [34]

Since each barber works 8 hours per day, it means that the barber shop conducts 112 haircuts in 8 hours. This means that it conducts

$\cfrac{112}{8} = 14$

cuts per hour. Every barber can conduct two haircuts per hour. This means that a generic number $b$ of barbers conducts $2b$ cuts per hour. But we already know that the shop conducts 14 cuts per hour, so the number of barbers is given by

$2b = 14 \iff b = \cfrac{14}{2} = 7$

Two high-speed ferries leave at the same time from a city to go to the same island. The first ferry, the Cat, travels at 37 mile

LenaWriter [7]

Step-by-step explanation: They will be 11 miles apart after 1 hour.

EXPLANATION: If they are going at 37 and 26 miles, you subtract the total and you get 11, so in this case since 11 is the number we are trying to find, after 1 hour they are going 11 miles apart.
