terms?
Answer:
s = -43.245
Step-by-step explanation:
First, you move the constant to the right:
-s=44-0.755
Calculate:
-s=43.245
Then, you change the signs:
s=-43.245
To explain your reasoning, you can say that:
To add any complex numbers together, you add the constants to each other and the numbers together.
Answer:
B. -2t^2+3t+4
Step-by-step explanation:
The standard form as
ax^2 + bx + c
Option B meets that requirement, even though it has a '-' in front
All the given polynomials, A. t^4-1, B. -2t^2+3t+4 and C. 4t-7 are in standard form since their terms are written in descending order of their degrees.
In mathematical terms, a polynomial is in standard form if its terms are written in descending order of their degree, i.e. the power of the variable. This means the term with the highest power should be listed first, followed by the term with the next highest power, and so on. Let's look at the options:
So, in conclusion, the polynomials in standard form from the provided options are A. t^4-1, B. -2t^2+3t+4 and C. 4t-7.

Answer:
27.76% probability that a randomly selected bag of this size has 10 or more green candies
Step-by-step explanation:
I am going to use the normal approximation to the binomial to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
Normal probability distribution
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that , .
In this problem, we have that:
So
What is the probability that a randomly selected bag of this size has 10 or more green candies
Using continuity correction, this is , which is 1 subtracted by the pvalue of Z when X = 9.5. So
has a pvalue of 0.7224
1 - 0.7224 = 0.2776
27.76% probability that a randomly selected bag of this size has 10 or more green candies
Answer:
Step-by-step explanation:
The number x of green candies in a bag of 40 candies follows a binomial distribution, because we have:
So, the probability that in a bag of 40 candies, x are green is calculated as:
Replacing, n by 40 and p by 0.2, we get:
So, the probability that a randomly selected bag of this size has 10 or more green candies is equal to:
Where
So, we can calculated P(0) and P(1) as:
At the same way, we can calculated P(2), P(3), P(4), P(5), P(6), P(7), P(8) and P(9) and get that P(x<10) is equal to:
Finally, the probability that a randomly selected bag of this size has 10 or more green candies is:
To calculate the cost per patient over the four-year period, we need to add up the costs for each year and then divide by the number of years.
The costs per patient for the four years are:
Year 1: $43
Year 2: $46.5
Year 3: $49.8
Year 4: $53.63
To find the total cost over the four years, we add up these costs:
$43 + $46.5 + $49.8 + $53.63 = $193.93
Now, we divide the total cost by the number of years (which is 4) to find the average cost per patient over the four-year period:
$193.93 / 4 = $48.48
Therefore, the cost per patient over the four-year period is approximately $48.48.
The cost per patient over the four-year period is $193.16.
To find the cost per patient over the four-year period, we need to calculate the percent increase for each year and then multiply the percent increase by the previous year's cost. Here are the steps:
Therefore, the cost per patient over the four-year period is $193.16.
