Which of the following equations will have a negative solution?
Answers
Answer:
The third equation, [tex]7\frac{1}{2} +m = 4\frac{2}{3}[/tex].
Step-by-step explanation:
In this question, we have to solve the equation for each of the options and after doing so we will see that the only option that will have m equal a positive number is the third option. Here is how we solve that equation:
[tex]7\frac{1}{2} +m = 4\frac{2}{3} \\m = 4\frac{2}{3} - 7\frac{1}{2}\\m = -2\frac{5}{6}[/tex]

Suppose that diameters of a new species of apple have a bell-shaped distribution with a mean of 7.23cm and a standard deviation of 0.35cm. Using the empirical rule, what percentage of the apples have diameters that are no more than 6.18cm? Please do not round your answer.
Answers
Answer:
0.15% of the apples have diameters that are no more than 6.18cm.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.23, standard deviation = 0.35.
What percentage of the apples have diameters that are no more than 6.18cm?
6.18 = 7.23 - 3*0.35
So 6.18cm is three standard deviations below the mean.
99.7% of the measures are within 3 standard deviations of the mean. The normal distribution is symmetric, which means that (100-99.7)/2 = 0.15% is 3 standard deviations or more below the mean, and 0.15% is 3 standard deviations or more above the mean.
Thus, 0.15% of the apples have diameters that are no more than 6.18cm.

The stadium vending company finds that sales of hot dogs average 35,000 hot dogs per game when the hot dogs sell for $2.50 each. For each 25 cent increase in the price, the sales per game drop by 2000 hot dogs. Determine a function R x that models the total revenue per game, where x is the number of $0.25 increases in the price of a hot dog.
Answers
Answer:
A function R x that models the total revenue per game is as follows:
Rx = 87,5000 + 3,750x – 500x^2.
Step-by-step explanation:
Based on the information in the question, we have:
Rx = Total revenue per game
x = Number of $0.25 increases in the price of a hot dog
Average sales of hot dogs = 35,000
Effect of each 25 cent increase in the price on average sales = 35,000 - 2000x
Effect of each 25 cent increase in the price on selling price = 2.5 + 0.25x
Therefore, we have:
Rx = (35,000 - 2000x)(2.5 + 0.25x)
This can be solved further by opening the brackets as follows:
Rx = 87,5000 + 8,750x - 5,000x - 500x^2
Rx = 87,5000 + 3,750x – 500x^2
Therefore, a function R x that models the total revenue per game is Rx = 87,5000 + 3,750x – 500x^2.

There are 14 horses and 56 camels at the stable. What fraction of animals in the stable are horses?
Answers
Answer:
1/4
Step-by-step explanation:
if you do it on a calculator it comes out to 0.25 which equals 1/4
Step-by-step explanation: Since there are 14 horses, 14 - 6 -5 = 3 are black.
a) 3 out of 14 are black, so probability is 3/14 chosen horse will be black
b) 1 - 3/14 = 11/14 probability will not be black
c) 6 are brown and 3 are black, so 9/14 probability chosen horse will be either.

The formula for the area of a trapezoid is:
[tex]\frac{(b_{1}+b_{2})*h}{2}[/tex]
Where b1 and b2 are the bases and h is the height. We are given 2.9 and 10.9 as the bases and 5.6 as the height. We can plug these values into the formula:
[tex]\frac{(2.9+10.9)*5.6}{2}[/tex]
After entering the expression in the calculator, you get:
38.64 km^2
This is the first option.

Half the circle = 25.12 squared inches
Area of a triangle = base x height /2
