The total amount of money that farmer will make to sell the tomatoes for $2 per tomato will be $14720.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
Multiplication = to multiply any two or more numbers or variables called multiplication.
The number of red tomato = 128 × 32
The number of yellow tomato = 102 × 32
The total cost will be,
2(128 × 32) + 2(102 × 32)
⇒ 2(4096) + 2(3264)

7.34 the gpas of all students enrolled at a large university have an approximate normal distribution with a mean of 3.02 and a standard deviation of .29. find the probability that the mean gpa of a random sample of 20 students selected from this university is
The probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher is 10.93%
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal probability distribution:Problems of normally distributed samples are solved using the z-score methods.
We know that, in a set with mean and standard deviation , the z-score of a measure X is given by:
Z = X - μ/σ
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 p-value, we get the probability that the value of the measure is greater than X.
Central Limit Theorem:The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a Skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
μ = 3.02 , σ = 0.29 , n = 20 and s = 0.29/√ 20 = 0.0648
Find the probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.
This is 1 subtracted by the p- value of Z when X = 3.10. So
By the Central Limit Theorem:
Z = X - μ / s
⇒ Z = 3.1 - 3.02/ 0.0648
⇒ Z = 1.23
The Z = 1.23 has a P- value of 0.8907
∴ 1 - 0.8907 = 0.1093
Now, for getting the percentage,
0.1093 × 100% = 10.93%
10.93% probability that the mean GPA of a random sample of 20 students selected from this university is 3.10 or higher.

Here is a scatterplot showing the relationship between the number of turnovers and the number of points scored for players in a recent NBA season. The correlation for these data is r = 0.92.
Interpret the correlation
Yes.There is a strong , positive association,so an increase in turnovers causes an increase in points for NBA players..
Given that,
This scatterplot illustrates the correlation between a player's turnover rate and their points scored during a recent NBA season. 3000 2500 2000 Points 1500 and r= 0.92
r = 0.92 A strong positive (upward sloping) linear relationship
While a correlation of 0.10 would be a modest positive correlation, a correlation of 0.97 is a significant negative correlation.
Hence, Yes. Because there is a significant positive correlation, more turnovers result in more points for NBA players.

Quotient is 51.97 by dividing 2,183 by 42. A quotient is the amount that results from dividing two numbers.
How to divide a number ?One of the four fundamental arithmetic operations, or how numbers are combined to create new numbers, is division. The additional operations are multiplication, addition, and subtraction.
Multiply the first fraction by the reciprocal of the second to divide rational expressions. We factor everything and search for common factors after rewriting the division as multiplication of the first statement by the reciprocal of the second. Separate logical expressions.
The number 2183 is called the numerator or dividend, and the number 42 is called the denominator or divisor.
The quotient of 2183 and 42, the ratio of 2183 and 42, as well as the fraction of 2183 and 42 all mean (almost) the same:

Graph of Cubic equationFrom the question, we are to determine graph of the given cubic equation.
The given cubic function is
f(x) = x³ - 10x² + 16x
To graph the equation, we will determine the value of f(x) for certain values of x
When x = 0
f(x) = x³ - 10x² + 16x
f(x) = (0)³ - 10(0)² + 16(0)
f(x) = 0
When x = 2
f(x) = x³ - 10x² + 16x
f(x) = (2)³ - 10(2)² + 16(2)
f(x) = 0
When x = 5
f(x) = x³ - 10x² + 16x
f(x) = (5)³ - 10(5)² + 16(5)
f(x) = -45
When x = 8
f(x) = x³ - 10x² + 16x
f(x) = (8)³ - 10(8)² + 16(8)
f(x) = 0
When x = 10
f(x) = x³ - 10x² + 16x
f(x) = (10)³ - 10(10)² + 16(10)
f(x) = 160

a machine makes 36 trophies every hour. The machine makes trophies for 8 and a half hours each day, on 5 days of the week. The trophies are pack into boxes. Each box holds 8 trophies.
How many boxes are needed for all the trophies made each week?
Answer: 1530
Step-by-step explanation: First, you would want to calculate how many are made in one day. 36 trophies are made per hour, for 8 1/2 hours. 36 x 8.5(8 and a half) is 306, so in one day, 306 are made. Then, all you have left is to multiply it by 5, for five days, and that would be 1530. Hope This Helps.
