<h3>What is a Frequency?</h3>
Frequency is the number of times a data point or a set of points within an interval appears often in a data set.
The corresponding frequency to each of the interval given for the data would be as follows:
50 - 54: 2
55 - 59: 6
60 - 64: 7
65 - 69: 3
70 - 74: 2

Answer:
p(x) = f(x) - g(x) = -0.04x² + 20.96x - 71
Explanation:
The sales are given by f(x) = 24.96x and the cost are represented by g(x) = 0.04x² + 4x + 71.
Then, the profit is equal to
p(x) = f(x) - g(x)
p(x) = 24.96x - (0.04x² + 4x + 71)
p(x) = 24.96x - 0.04x² - 4x - 71
p(x) = -0.04x² + 20.96x - 71
Therefore, the answer is
p(x) = f(x) - g(x) = -0.04x² + 20.96x - 71
Answer:
A) 20ml
Step-by-step explanation:
You have a 2.5% solution (in 100 of the solution you have 2.5 of solvent), then if the dose that is being supplied to the cat is 5mg / kg it means:
if 1000 gr is equivalent to 100%
5 gr is equivalent to X;
X= (100%*5gr)/1000gr → X= 0.5%, , Therefore the amount of milliliters that should be supplied of 2.5% is:
if 100ml hava a concentration of 2.5, how many mililiters are necesary in a concentration 0.5
X=(0.5%*100ml)/2.5% → X=20ml
Answer: P = A/6
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
