Answer:

[tex]1.8[/tex]

Step-by-step explanation:

Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:

[tex]T\propto \frac{1}{H}[/tex]

Convert 5 minutes to seconds:

[tex]5\cdot 60=300\:\mathrm{s}[/tex]

Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.

[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]

Step-by-step explanation:

Larval mosquitoes breath through trachea in their siphons. This is a structure analogous to the snorkel on a diesel electric submarine. It allows for gas exchange with the atmosphere while the remainder of the insect is submerged. The opening of the siphon is hydrophobic so it won’t get wet and blocked by water. This works well to keep the siphon and the trachea open under normal conditions. Oil when poured on water forms a thin film. When there are mosquitos in that water, when their siphons contact the oil layer, the oil wets and blocks their siphons and suffocates the mosquitoes. This works against most, but not all mossies, as evolution is an amazing process. Some mosquitoes (Mansonia, Coquilletidia) have a siphon designed to penetrate the air vessels in aquatic plants and they don’t need to come to the surface to breath like other mossies. So oil won’t work on these genera.

Answer: 9√2

Step-by-step explanation:

The length of each side of the square is 109/25 units.

Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².

The length of the diagonal of the square in given figure is 9 units.

Suppose each side of square be x unit.

Apply Pythagoras theorem to obtain length of the side as follows,

x² + x² = 9²

=> 2x² = 81

=> x² = 81/2

=> x = 6.36

       = 636/100

       = 159/25

Hence, the value of x in the simplest radical form is 6.36 units.

Answer:

The smaller number is -9.

Step-by-step explanation:

Let x and y be the two unknown numbers.

Their sum is -5. Hence:

[tex]x+y=-5[/tex]

Their difference is 13. Hence:

[tex]x-y=13[/tex]

This yields a system of equations. We can solve this using elimination. Adding the two equations together:

[tex](x+y)+(x-y)=(-5)+(13)[/tex]

Simplify:

[tex]2x=8[/tex]

Divide both sides by two. Thus:

[tex]x=4[/tex]

Using either equation (I'll use the first):

[tex](4)+y=-5\Rightarrow y=-9[/tex]

So, our two numbers are 4 and -9.

The smaller number is -9.

The item can be anything really. I'm going to add a trampoline which is a square shown in purple. The square is rotated 45 degrees so it looks like a diamond shape. The rotation isn't necessary but I figured to spice things up compared to the other figures which were mostly squares or rectangles. If we split the purple square into 4 triangles, and apply the pythagorean theorem, then we can find the length of each side of the purple square to be roughly 2.828 cm.

Scaling things up, the trampoline in real life is 2*2.828 = 5.656 meters along each dimension.

With any square the angles are always 90 degrees.

The formula for the area of a circle is:

Answer:

The answer is 28 ft

Step-by-step explanation:

Since two sevenths of the height of a sailboats tallest mast is 8 feet, we keep adding two sevenths until we get its tallest mast.

2/7 = 8 ft

4/7 = 16 ft

6/7 = 24 ft

(Adding 1/7 which is 4 feet)

we get 7/7 = 28 ft

Reject the null hypothesis and come to the conclusion that there is enough evidence to imply that the percentage of adults who are familiar with the company's name is much more than 40%.

In order to evaluate whether the percentage of individuals who recognize the company's brand name differs considerably from the company's target of 40%, we must conduct a hypothesis test.

Let p represent the percentage of adults who can name the company's brand. The corporation hopes that more than 40% of adults will recognize its brand name, hence the alternative hypothesis is that p > 0.4.

A one-sample z-test can be used to examine this claim. The test statistic is determined as follows:

[tex]z = \dfrac{(p' - p)} { \sqrt{\dfrac{(p (1 - p)} { n}}}[/tex]

Where p is the null hypothesis value, n is the sample size, and p is the sample proportion.

In this instance, n = 420, p = 0.4, and p' = 181/420 = 0.431. With these values entered into the formula, we obtain:

[tex]z = \dfrac{(0.431 - 0.4)} { \sqrt{(0.4 \times \dfrac{0.6} { 420} }}= 1.65[/tex]

The likelihood of obtaining a z-value of 1.65 or higher is 0.0495 using a basic normal distribution table or calculator (assuming the null hypothesis is true). This is the test's p-value.

When the p-value is less than 0.05, which is considered to be significant (and corresponds to a 95% confidence level), we

Hence, based on this sample of 420 adults, we would advise the company to keep running Super Bowl advertisements as it seems to be succeeding in raising brand recognition among the general public.
