The triangles below are simular. which statement about the triangles is true?

Answer:

There is significant evidence that Jane has met the requirement.

Step-by-step explanation:

Given that:

μ = 100

μ > 100

Sample size, n = 16

Sample mean, x = 108

Sample standard deviation, s = 12

Level of significance, α = 0.1

Degree of freedom, df = n - 1 = 16 - 1 = 15

Test statistic

T = (x - μ) / s÷sqrt(n)

Tstatistic = (108 - 100) / 12 ÷ sqrt(16)

Tstatistic = 8 / 3

Tstatistic = 2.6667

Using the pvalue calculator :

Tstatistic at 0.1, df = 15 ;

P-value = 0.008799

Since pvalue < α

We reject the Null

The is no significant evidence to conclude that Jane has exceeded an average of more than $100

Step-by-step explanation:

Approximately 0.2% of the apples will be more than three standard deviations above the mean size. In a bin of 100 apples, 0.2% of 100=0.2% apples, this rounds down to zero apples that size or larger. (In a bin of 500 apples, there could be one apple of that size.)

Answer:

[tex]y + x = 3[/tex]

Step-by-step explanation:

The question is poorly formatted. However, I will take the parameters as follows:

Given

Perpendicular to: J(-3,2) and L(2,7)

Passes through: (3,0)

Required

Write an equation for the line

First, calculate the slope (m) of JL

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{7-2}{2+3}[/tex]

[tex]m = \frac{5}{5}[/tex]

[tex]m = 1[/tex]

Since the line is perpendicula4 to JL, the slope is:

[tex]m_2 = -\frac{1}{m}[/tex]

[tex]m_2 = -\frac{1}{1}[/tex]

[tex]m_2 = -1[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 0 = -1(x - 3)[/tex]

[tex]y - 0 = -x + 3[/tex]

[tex]y = -x + 3[/tex]

[tex]y + x = 3[/tex]

Answer:

The height of the building is of 244.95 feet.

Step-by-step explanation:

We use the Pythagorean Theorem to solve this question.

We have that:

The shadow of 50 feet is one side of the right triangle, while the height h is other side.

The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.

So

[tex]50^2 + h^2 = 250^2[/tex]

[tex]h^2 = \sqrt{250^2 - 50^2}[/tex]

[tex]h = 244.95[/tex]

The height of the building is of 244.95 feet.

Answer:

The responses to this questin can be defined as follows:

Step-by-step explanation:

Take system A. The predator must be there. If we feel the attacker is x, that drop in y (a further prey eaten) must raise by x. Growing x could render y falling much quicker because more predators become available. See the equation of [tex]\frac{dx}{dt}[/tex].

[tex]\frac{dx}{dt} = 3x(1- \frac{x}{10})-20xy[/tex]

It will see that dx/dt is an x both y function. It is indeed difficult to tell something about the dependence among [tex]\frac{dx}{dt}[/tex] and x, but it is quite easy: the higher to y, its higher the 20xy (since x and y are positive numbers). And therefore -20xy is much more negative, but [tex]\frac{dx}{dt}[/tex] is much worse. Going to find: the larger y, the less or even more negative [tex]\frac{dx}{dt}[/tex], the less x.

Test: It implies that higher y means less x (more prey) (fewer predators). Then, does the assumption which x is a predator confirmed? No, because more prey, and thus more predators, would mean better lunch for both the predators, People could see that x is now a prey as well as y a predator, even though more predators(y) exist.

They use the second equation to check this:

[tex]\frac{dy}{dt} = -\frac{5y+xy}{20}[/tex]

Perhaps, now we're just talking about basic dependency as of now: one is from dy/dt to x. A larger x means that the y (predator) is growing faster. For System B we are using the same rationale.Thus, x is a predator and y a predator (as high x indicates higher 25 x but this results in increased y population increase (EQ.2), as higher x means lower [tex]\frac{XY}{100}[/tex] and reduces x) Afterwards, we would like to learn which system has big and small predators. To conclusion, they must realize that this piranha does not impact that population of humans in the case of piranhas. However in cases where y = I and y = i+1 would not significantly differ from [tex]\frac{dx}{dt}[/tex] (alter in the number of individuals) (i is an arbitrary number of piranhas)

This function of system B can be seen: [tex]\frac{dx}{dt} = 0.3x - \frac{xy}{100}[/tex]. And what's the reason? Given the fact that the element beside y is [tex]\frac{1}{100}[/tex], another tiger shark is no worse than [tex]\frac{dx}{dt}[/tex] and therefore not willing to make a significant contribution to the elimination of global life. Through system A, they could see that the predator is huge because one predator implies a major shift in [tex]\frac{dx}{dt}[/tex] almost. I belive that, this message has been observed by you. But I also hope that throughout the end I have created no error:) This should try to not learn with your heart, since it is helpful when you grasp the task. Another way to approach the problem might be to try to consider [tex]\frac{dy}{dt}[/tex] instead of [tex]\frac{dx}{dt}[/tex] for both systems and then to see that what prey is tiny or large. This big predator should not imply many hunters with one location or each other and will eat a meal (System A seems to have this feature: [tex](\frac{dy}{dy} = -5y)[/tex]

Step-by-step explanation:

Answer:

radius = 6

apothem = 4.85

side length = 7.05

Step-by-step explanation:

sin 36 =x/6, x= 3.53, side length = 7.05

cos 36 = apothem/6, apothem = 4.85

Therefore, the values of the pentagon is the radius is 6, apothem=4.8 and the side length =3.48.

A pentagon is one of the many types of polygon having five sides and five angles. The word 'Pentagon' arises from two words, that are, ‘Penta’ and ‘Gonia,’ meaning five angles.

Let x be the side length of the pentagon.

As per the given information;

Apothem is the line from the center of the pentagon to a side, intersecting the side at 90 degrees right angle.

Sin(36) = x / 6

x = 6 × sin(36)

side length x = 6 × (0.58)

side length x  = 3.48

And

cos(36) = apothem / 6

Apothem = 6 cos36

Apothem = 6 (0.80)

Apothem = 4.8

Hence, the radius is 6, apothem=4.8 and the side length x=3.48.

The Highest common factor of 120,140,180 is  ( HCF) = 20

Step-by-step explanation:

Explanation:-

Given numbers  120,140,180

120 = 60 × 2

     = 30 × 2× 2

     = 15 × 2×2×2

    = 5×3× 2×2×2

Answer:

200 minutes of calls

Step-by-step explanation:

Let x represent the number of minutes of calls

Set up expressions that represent the costs for each plan:

0.14x + 21 can represent the first plan

0.10x + 29 can represent the second plan

Now, set them equal and solve for x to find when they will be equal:

0.14x + 21 = 0.10x + 29

0.04x + 21 = 29

0.04x = 8

x = 200

So, the costs will be equal with 200 minutes of calls

Answer:

76x2 = 152

280 - 152 = 128

128 ÷ 2 = 64

Answer:

the width is 64cm

Step-by-step explanation:

a rectangle has 4 sides, each set of opposite sides are congruent, perimeter is the distance around an object, so we need to add up all 4 sides and it should equal 280cm, we know one side is 76, so our equation should look as follows:

76 + x + 76 + x = 280

2x + 152 = 280

2x = 128

x=64

you can check the answer but substituting 64 for x and seeing if it comes out to 280

76+64+76+64=280

280=280
