Answer: -2
Step 1: Write an equation
Before we are able to solve, we need to write an equation. We can do this by breaking down the equation. We are told to find the sum of -4 and the difference of another two numbers. Sum means addition, so we will add -4 to the difference of 3 and 1. Because we are adding to the difference, we will put 3 and 1 inside of parentheses, and find the difference before we add. Knowing this, we can write the equation. Let’s do this now.
-4+(3-1)
Step 2: Solve
Now that we have the equation we can solve for the answer. Let’s start by finding the difference, as indicated by the parentheses. After that, we can find the sum of that number and -4 by adding them together. We can do this now.
-4+(3-1)
-4+2
-2
This is your answer! The sum of -4 and the difference of 3 and 1 is -2. Hope this helps! Comment below for more questions.
So the first thing you do is you divide 1024 by 256. you will come out with the answer of 4. it takes 4 seconds to download 1 megabyte. but, it takes 4 megabytes, so you need to multiply 4 by 4. you will get 16. it takes 16 seconds to download 1 song.
to figure out how many songs Lindy can download in 2 hours, you multiply 60 by 60. you will get an answer of 3600. there are 3,600 seconds in an hour. now to find out how many are in 2 hours you multiply 3,600 by 2. you will get a sum of 7,200
now to figure out how many songs Lindy can download in 2 hours, you divide 7,200 by 16. you will come out with a quotient of 450.
Lindy can download a total of 450 songs in the space of 2 hours.
Answer:
Step-by-step explanation:
Represent Green with G
So,
Required
Determine the probability that 10 out of 16 prefer green
This question is an illustration of binomial distribution and will be solved using the following binomial distribution formula.
In this case:
-- number of people
-- those that prefer green
So, the expression becomes:
Substitute 50% for G (Express as decimal)
Apply law of indices
Solve 16C10
<em>Hence, the required probability is 0.1222</em>
