Suppose you flip a coin and spin a spinner that is divided into 8 equal regions. Of the 8 equal regions, 3 are red, 4 are black and 1 green. What is the probability of "tails" on the coin, and the spinner landing on red?
 (Hint: How many spaces are on the spinner total?)Immersive Reader(5 Points)

Answers

Answer:

18.75%

Step-by-step explanation:

The probability of the coin is 1/2, because it only has two options (tail or head).

Now, in the case of roulette, it has a total of 8 options, and the red region has 3 parts, that is, of the 8 options, roulette 3 is red, therefore the probability is 3/8

Now the final probability is the multiplication of the probability of both events:

(1/2) * (3/8) = 0.1875s 18.75%

In other words, the probability of these two events happening, that the tail comes out and is red, i

How many solutions does the system 2y=10x-14 and 5x-y=7 have

Answers

Answer: 1 solution at (2.8, 7)

Answer:

All real numbers

Step-by-step explanation:

Take 2y=10x-14 and divide both sides by 2. Once you do that, you get y=5x-7. Use substitution and plug that into 5x-y=7. You get 5x-(5x-7)=7 which eventually simplifies to 7=7 which shows that you can plug in an infinite number of solutions so the answer is all real numbers.

A colony of bacteria is growing exponentially according to the function below, where t is in hours. What will the approximate number of bacteria after 7 hours? B(t)=4*e^0.8t Answers: A. 45,674 / B. 1082 / C. 270 / D. 635,818

Answers

We are given with the situation of bacteria multiplying into colonies. We are given also with the function of B(t)= 4e^0.8t where t is the time of multiplication. We just have to substiture the given time of 7 hours to find teh final count. The answer is approximately 1082. Answer is  B. 

The approximate number of bacteria after 7 hours is 1082.

We are given with the situation of bacteria multiplying into colonies.

We are given also with the function of B(t)= 4e^0.8t

where t is the time of multiplication.

What is the exponential function?

A function whose value is a constant raised to the power of the argument, especially the function where the constant is e.

We just have to substitute the given time of 7 hours to find teh final count.

The answer is approximately 1082.

Therefore the correct option is  B.

Give the nth term and the next term of this

8,13,18,23,28

Answers

so it's add 5 to each so the next term would be 33

so first term is 8 so
1st term=8
2nd term=8+5 so therefor the equation is
the nth term is 8+5n-5
so therfor first term is 8+5(1)-5=8+5-5=8

second term=8+5(2)-5=8+5=13

equation is nth term=8+5n-5
Your answer is going to be 33. All it is doing is adding up 5
