The sum of the surfaces of the five faces of a triangular prism is its surface area.

Having two triangular bases and three rectangular sides, a triangular prism is a type of polyhedron. It is a three-dimensional object with two base faces and three side faces that are joined by edges.

There are 6 vertices, 5 edges, and 5 faces on it. The other 3 faces have a rectangle-like shape, while the 2 bases are structured like a triangle. Camping tents, chocolate candies, roofs, etc. are a few instances of triangular prisms in the real world.

A solid object called a prism has plane faces enclosing each of its four sides. Faces in a prism come in two different varieties. Bases are used to describe the top and bottom faces, which are identical.

12 cm is the triangle's base.

triangle's height is 8 cm.

Triangle's length is 32 cm (10 + 10 + 10 cm).

Triangle width is 16 cm.

The rectangle's area is 512 cm2 (l x b = 32 x 16).

Triangle area equals 1/2 x 12 x 8 = 48 cm2.

Two triangles are present, therefore 48 + 48 = 96 cm2.

512 + 96 = 608 cm2 after adding all these values.

Answer: 5/2187

Step-by-step explanation: The equation for geometric sequence is (a (subroot) n = a (subroot) 1) x ratio^(n-1).

The ratio of the perimeter of the smaller to larger rectangle is 3:4

The dimension of the smaller rectangle = 3 by 9

The dimension of the larger rectangle = 5 by 11

The perimeter of a rectangle is given by the relation :

Perimeter = 2(Length + width)

Perimeter of smaller rectangle = 2(3+9) = 24 ft²

Perimeter of larger rectangle = 2(5+11) = 32 ft²

Answer:$182

Step-by-step explanation:

so 17.3333333333 * 10.5 = 182

Since the test statistic (2.53) falls within the critical values (-2.576 and 2.576), we fail to reject the null hypothesis.

To test the claim that the proportion of American adults who eat salad once a week is equal to 80%, we will conduct a hypothesis test.

Claim: p = 0.80

Opposite: p ≠ 0.80

The test is a two-tailed z-test.

Sample proportion (p) = 374/445 = 0.8404

Test statistic= (0.8404 - 0.80) / sqrt((0.80 * (1 - 0.80)) / 445)

z = 2.53 (rounded to 2 decimals)

Significance level (α) = 0.005, so the critical values for a two-tailed test are -2.576 and 2.576.

Since the test statistic (2.53) falls within the critical values (-2.576 and 2.576), we fail to reject the null hypothesis.

The tangent at any point of a circle is perpendicular to the radius through the point of contact by showing that line PQ coincides with the radius OP.

Let us assume that we have a circle with center O and radius r.

Let P be any point on the circle .

And let Q be the point of intersection of the tangent to the circle at P and the radius OP,

To prove that PQ is perpendicular to OP.

First, we observe that OP is a radius of the circle and therefore its length is r.

Since PQ is tangent to the circle at point P,

It is perpendicular to the radius drawn from the center of the circle to point P.

As the tangent to a circle is perpendicular to the radius drawn to the point of contact.

This implies, angle QOP is a right angle.

Next, triangle OPQ is a right triangle with right angle at Q.

By the Pythagorean Theorem, we have,

OP²= OQ² + PQ²

Substituting r for OP and noting that OQ = r since Q is on the radius. we have,

⇒ r² = r²+ PQ²

Subtracting r² from both sides, we get,

⇒ PQ² = 0

This implies that PQ = 0,

In other words, that point Q coincides with point P.

PQ is a line that coincides with the radius OP.

And since angle QOP is a right angle, we can conclude that PQ is perpendicular to OP.

Therefore, it is proved that the tangent at any point of a circle is perpendicular to the radius through the point of contact.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Let x represent the length of fence parallel to the river. Then the dimension of perpendicular to the river will be half the remaining fence: (640-x)/2. The total area will be ...

  A = x(640-x)/2

This is the equation of a parabola that opens downward. It has zeros at x=0 and x=640, so its axis of symmetry is x = (0+640)/2 = 320. That is, the peak of the area curve is found when x=320.

The dimensions of the garden with the largest area are 160 ft wide by 320 ft long, where the long side is the river side.

Mrs. Grubbs would get more cookie to eat by choosing the 4 smaller cookies with diameter 5 cm each rather than the single cookie with diameter 14 cm.

To compare the amount of cookie Mrs. Grubbs would get by eating a single cookie with diameter 14 cm and 4 smaller cookies with diameter 5 cm each, we need to consider the total area of the cookies.

The area of a cookie with diameter 14 cm can be calculated as follows:

A = πr^2 = π(7 cm)^2 = 49π cm^2

where r is the radius of the cookie.

On the other hand, the area of a single small cookie can be calculated as follows:

A1 = \(πr^2\) = \(π(2.5 cm)^2\)= \(6.25π cm^2\)

where r is the radius of the small cookie.

Therefore, the total area of 4 small cookies is:

A2 = 4A1 = \(4(6.25π cm^2)\) = \(25π cm^2\)

Comparing the two options, we see that the total area of the 4 small cookies is greater than the area of the single large cookie:

A2 > A

\(25π cm^2 > 49π cm^2\)

It's worth noting that this comparison assumes that the thickness or volume of the cookies is the same for both options. If the cookies have different thicknesses, then the comparison would need to take into account the volume of the cookies instead of just the area.

Answer:

\(f(n) = f(n- 1) * 2\); \(f(1) = 3\)

Step-by-step explanation:

Given

\(1\ minute = 3\ friends\)

Every other minute

\(Each\ friend = 2\ other\ friends\)

Required

Determine the recursive function

Let the number of minutes be represented with n.

The initial condition can be represented as:

\(n = 1\)

\(f(1) = 3\) --- i.e. 3 friends initially at the first minute

At every other minutes:

\(n \ge 2\) i.e 2 minutes upwards

This means that n follows the following sequence

\(n \to n, n -1, n -2,n -3, n - 4,.....,4,3,2\)

Note that the difference between each term is 1.

This means that recursive function has to be defined backwards i.e.

\(f(n) = f(n- 1) * k\)

Where k = 2

i.e. The number of friends that received the video from each friend

So, we have:

\(f(n) = f(n- 1) * 2\)

Hence, the recursive function is:

\(f(n) = f(n- 1) * 2\); \(f(1) = 3\)

Step-by-step explanation:

1. You know what 2^3 is, right? That's 2*2*2. 2*2 is 4, and then 4*2 is 8. So that is 3/8.

2. (-1/4)^2 is (-1/4)*(-1/4), right? So that is (-1*-1)/(4*4). Two negatives make a positive, so -1*-1=1. 4*4 is 16, so we have 1/16.

Answer:

 \(P(X  < 35) =  32.3 \%\)

b

\(P(\= X  < 35) =  0.6 \%\)

Here the probability of koalas mean temperature being less than 35 °C is very small hence the koalas are not healthy

c

A potential confounding variable for this study is  the population of the koalas because in the first question the population was not taken into account and the probability was  \(P(X  < 35) =  32.3 \%\) but when the population was taken into account (i.e  n =  30) the probability became

\(P(\= X  < 35) =  0.6 \%\)  

Step-by-step explanation:

From the question we are told that

  The mean is  \(\mu =  35.6^oC\)

   The standard deviation is  \(s =  1.3^oC\)

   The sample size is  n = 30

Generally the  probability that a health koala has a body temperature less than 35.0°C is mathematically represented as

     \(P(X  < 35) =  P(\frac{X  - \mu }{s}  < \frac{35 - 35.6}{1.3} )\)

Here  \((\frac{X  - \mu }{s} =  Z (The   \ standardized \  value \  of  \  X )\)

So

    \(P(X  < 35) =  P(Z < -0.46)\)

From the z-table  P(Z <  -0.46) =  0.323

So  

    \(P(X  < 35) =  0.323 \)

Converting to percentage

      \(P(X  < 35) =  0.323  * 100 \)

      \(P(X  < 35) =  32.3 \%\)

considering question b

The sample mean is  \(\= x =  35\)

Generally the standard error of the mean is mathematically represented as

   \(\sigma_{\= x} =  \frac{s}{\sqrt{n} }\)

=>  \(\sigma_{\= x} =  \frac{1.3}{\sqrt{30} }\)

=>  \(\sigma_{\= x} =  0.2373 \)

Generally the probability of the mean body temperature of koalas being less than 35.0°C is mathematically represented as

 \(P(\= X  < 35) =  P(\frac{\= X  -  \mu  }{\sigma_{\= x }} <  \frac{35 -35.6}{0.2373 }  )\)

\(P(\= X  < 35) =  P(Z< -2.53  )\)

From the z-table  we have that

   \(P(Z< -2.53  ) =  0.006\)

So

 \(P(\= X  < 35) = 0.006 /tex]

Converting to percentage

      \(P(\= X  < 35) =   0.006  * 100 \)

      \(P(\= X  < 35) =  0.6 \%\)

Here the probability of koalas mean temperature being less than 35 °C is very small hence the koalas are not healthy

A potential confounding variable for this study is  the population of the koalas because in the first question the population was not taken into account and the probability was  \(P(X  < 35) =  32.3 \%\) but when the population was taken into account (i.e  n =  30) the probability became
