The counterexample for the conditional statement "If two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers" will be 2/3 x 9.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.
It is given if the two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers.
If the two positive numbers are x and y from the given condition,
xy > x
xy> y
The two numbers are obtained as 2/3 and 9.
=2/3 x 9
=6
Thus, the counterexample for the conditional statement "If two positive numbers are multiplied together, then the product will be greater than both of the two positive numbers" will be 2/3 x 9.

Solve for x: 2/5 = x/24
Answer:
x=9.6
Step-by-step explanation:
We are given the proportion:
[tex]\frac{2}{5}=\frac{x}{24}[/tex]
We are asked to solve for x. Therefore, we must isolate x on one side of the proportion.
x is being divided by 24. The inverse of division is multiplication. Multiply both sides of the proportion by 24.
[tex]24*\frac{2}{5}=\frac{x}{24}*24[/tex]
[tex]24*\frac{2}{5}=z[/tex]
[tex]24*0.4=x[/tex]
[tex]9.6=x[/tex]
[tex]x=9.6[/tex]
x is equal to 9.6 The complete proportion is [tex]\frac{2}{5}=\frac{9.6}{24}[/tex]

A poultry farmer wishes to estimate the average incubation period (the number of days between a hen laying her egg and the time the egg hatches) for eggs on his farm. He plans to take a sample and make a 98% confidence interval, and would like a margin of error of half a day. It is known that the distribution of incubation lengths has a standard deviation of 1.5 days. How many eggs does he need to sample to create the desired interval
Answer:
49 eggs.
Step-by-step explanation:
The formula for Margin of Error =
z × standard deviation/√number of samples
z = z score of 98% confidence interval = 2.326
Margin of Error = Half a day = 1/2day = 0.5 day
Standard deviation = 1.5 days
Number of samples = number of eggs he needs to sample = unknown.
Imputing these above values into the formula
Margin of Error = z × standard deviation/√number of samples
0.5 = 2.326 × 1.5/√n
Cross Multiply
0.5 × √n = 2.326 × 1.5
√n = 2.326 × 1.5/0.5
√n = 3.489/0.5
√n = 6.978
Square both sides
(√n)² = 6.978²
n = 48.692484
n ≈ Approximately to the nearest whole number = 49
Therefore, the number of eggs he needs to sample to create the desired interval is approximately to the nearest whole number 49 eggs

Form the graph it is clear that the lines intersect each other at (2,-1).
Therefore, the solution of given system of equations is (2,-1).
Cookies cost $3 each, and candies cost $2 each. Tim has
$25. Which inequality represents the number of cookies, x,
and the number of candies, y, that Tim can buy?
Answer:
8x < 12y
Step-by-step explanation:
If you divide 25 by 3, you get 8.3333... (the threes go on forever), which you can round to 8, because little Timmy isn't going to buy .3 of a cookie. If you divide 25 by 2, you get 12.5, which you round down to 12. I know you normally don't round 5 down, but we are talking about food here.
Therefore, Tim can buy less cookies than candies. He can buy 8 cookies, and 12 candies.
Either way, Timmy's gonna be fat.

Minus 2x on both sides
4 = 4x - 10
Add 10 on both sides
14 = 4x
Divide by 4 on both sides
14/4 = x
x = 14/4

The graph shows the distribution of weights (in pounds) of male duck-billed platypuses. The distribution is approximately Normal, with a mean of 3.75 pounds and a standard deviation of 0.52 pounds. What percent of male duck-billed platypuses have a weight of between 2.71 and 4.79 pounds?
Answer:
Choice B) The distribution is approximately Normal, with a mean of 3.75 pounds and a standard deviation of 0.52 pounds.
Step-by-step explanation:
Using the normal distribution principle, the percentage with weight between 2.71 and 4.79 is 95.45%
Using the Zscore relation :
Zscore = (X - μ) ÷ σFor X = 2.71 :
Zscore = (2.71 - 3.75) ÷ 0.52 = - 2
Using a normal distribution table :
P(Z < - 2) = 0.02275
For X = 4.79 :
Zscore = (4.79 - 3.75) ÷ 0.52 = 2
Using a normal distribution table :
P(Z < 2) = 0.97725
P(Z < 2) - P(Z < - 2) = 0.97725 - 0.02275 = 0.9545
Therefore, the required percentage is 95.45%
