Answer:

I think its 2/3 x 9

Step-by-step explanation:

My apologies if that isn't correct!

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.

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.

Answer:

7

Step-by-step explanation:

You have to put the numbers in order then find the middle number.

Numbers in order: 2,3,6,6,7,8,8,8,15

Then cross out the numbers on the end (one by one) until you get to the middle number. (If there are two numbers left once you're done then you add them then divide by 2)

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.

Answer:

x=11

Divide both sides of the equation by 2

4+3x=37

Subtract 4

3x=37-4

Subtract 37-4

3x=33

and divide by 3

x=11

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

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 :

For 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%

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]
