the surface area of a square pyramid with side length 2 cm and slant height 5 cm.​

Answer:

6.4

Step-by-step explanation:

when rounding a number, the decimal points go from tenth, hundredth, and thousandth.

In this case, the number in the tenths place is 4.

Because the number next to 4, which is 2, is less than 5, it cannot raise the number of the number in the tenths place, so the 4 stays the same and the other two numbers after it are eliminated

This gives you 6.4 as your final answer.

I hope this helps you!

a. the probability of finding exactly 6 defects in a carpet roll is approximately 0.0403.

b. the probability of finding 3 or fewer defects in a carpet roll is approximately 0.135.

A) The probability of finding exactly 6 defects in a carpet roll can be calculated using the Poisson probability formula:

P(X = 6) = (e^-λ) * (λ^6) / 6!

where λ = 2.0 (the average number of defects per roll), and e is the mathematical constant approximately equal to 2.71828.

Plugging in the values, we get:

P(X = 6) = (e^-2) * (2^6) / 6! = 0.0403

So the probability of finding exactly 6 defects in a carpet roll is approximately 0.0403.

B) To find the probability of finding 3 or fewer defects in a carpet roll, we need to calculate the cumulative probability:

P(X ≤ 3) = Σ_{i=0}^3 P(X = i) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)

where P(X = i) is the probability of finding exactly i defects, which can be calculated using the Poisson probability formula.

Plugging in the values and adding the probabilities, we get:

P(X ≤ 3) = (e^-2) + (e^-2) * (2^1) / 1! + (e^-2) * (2^2) / 2! + (e^-2) * (2^3) / 3!

P(X ≤ 3) = 0.135

So the probability of finding 3 or fewer defects in a carpet roll is approximately 0.135.

Statistical conclusion validity is the extent to which inferences and conclusions drawn from statistical data are valid.

The main threat to statistical conclusion validity discussed in class is the potential for spurious correlations. This is when two variables appear to be related when in fact they are not.

Statistical conclusion validity is a measure of how valid the conclusions drawn from statistical data are. This is important because it allows us to draw valid inferences from the data. The main threat to statistical conclusion validity discussed in class is the potential for spurious correlations. This is when two variables appear to be related when in fact they are not. For example, a study may show that there is a correlation between ice cream sales and crime rate, when in fact it is merely a coincidence that both variables increase during the summer months. By controlling for other variables and using appropriate statistical tests, it is possible to identify and avoid spurious correlations.

The surface area of the given prism is 3744 square cm.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

Here the prism contains six surfaces out of these two are trapezoidal and the other is rectangular so the total surface area will be the sum of the area of the trapezoid and the rectangles.

The surface area will be calculated as,

SA = 2 [(24/2)(29+12) + ( 12 x 30 ) + ( 26 x 30 ) + ( 25 x 30 ) + ( 29 x 30)

SA = 984 + 360 + 780 + 750 + 870

SA = 3744 square cm

Therefore, the total surface area will be 3744 square cm.

Answer: 288.9

Step-by-step explanation:

Circumference of a circle is dπ.

So as you have the circumference we are trying to find the diameter so you would do 907.46/π=288.8534893 or 288.9 (1 decimal place)

Answer:

option 4

Step-by-step explanation:

Probability = number of favourable outcomes / total number of possible outcomes

total number of codes with an all odd digit = 3 x 5 x 7 x 2 = 120

total number of possible outcomes = 10 x 9 x 8 x 7 = 5040

probability all digits are odd = 120 / 5040

probability that the code does not consist of all odd digits = 1 - probability all digits are odd

1 - 120 / 5040 = 4920 / 5040

The magnitude of the vector sum of the four vectors = 278.158M

What is Magnitude?

The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics. Formally speaking, the size of an object is the displayed outcome of an ordering—of the class of objects to which it belongs.

A = 82(cos 64 degree x +sin 64 degree y )

= 35.946 x +73.701y

B = 82 X

C= 82 Xx

D= 82 x (cos 64 degree x +sin 64 degree y)

= 35.946 x +73.701y

net = A+B+C+D

= X (35.946+82+82+35.946) + (2*73.701)

=235.892 X + 147.402Y

The vector DC in terms of p is 2/3p and vector BC in terms of p and q is q + 1/2p

Given that,

ABCD is a trapezium.

An identical one pair of opposite sides that are parallel to one another make up a trapezium, which is a convex quadrilateral. When represented as a table on a piece of paper, the trapezium is a two-dimensional shape. A polygon with four sides and four vertices is referred to as a quadrilateral in Euclidean geometry. Because of this, a trapezium also has four vertices, four angles, and four sides.

To find : The vector DC in terms of p  and vector BC in terms of p and q.

a) DC /AB = 3/2 ⇒

DC = 3/2AB = 3/2p

Answer:

= 30m

Step-by-step explanation:

to find the length of the fence, find the perimeter of the triangle.

that is b + h + hyp assuming b is the base, h is height and hyp is hypotenuse.

we have the base; height and hypotenuse are not given.

to get the height,

area(A) = 30m2

base(B) = 12m

height(H) = ?

A = 0.5 x B x H

30m2 = 0.5 x 12m x H

30m2 = 6m x L

H = 30m2 / 6m

H = 5m

to get the hypotenuse,

we have to complete the Pythagorean family the base ,12, and height, 5. is in.

formula = a2 + b2 = c2, c is the hypotenuse, a and b can be interchanged either way with base and height.

             = (12 x 12) + ( 5 x 5) = c2

             = 144 + 25 = c2

             = 169 = c2

        c2 = 169

        c = 13

perimeter = b + h + hyp

                = 5 +12 + 13

                 = 30m

This answer is y -7x.Hope you like answer

The point-slope form of the equation y=2x-7 will be y + 7 = 2(x - 0).

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation of the line is y = 2x - 7. The point-slope form of the equation of the line will be written as:-

y = 2x - 7

y - (-7) = 2( x - 0 )

y + 7 = 2( x - 0 )

Therefore, the point-slope form of the equation y=2x-7 will be y + 7 = 2(x - 0).

The break-even point for the given equation c = 15n + 269,000  , r = 95n  representing cost and revenue is equal to Option c. 3363units ( round up to nearest whole unit ).

As given in the question,

Cost equation is represented by :

c = 15n + 269,000

Revenue equation is given by ;

r = 95n

For the break-even point the cost is always equal to the revenue as there is no profit no loss.

c = r

15n + 269,000 = 95n

⇒ 95n - 15n = 269,000

⇒ 80n = 269,000

⇒ n = 269,000 / 80

⇒ n = 3362.5

Answer:

5x^3+15x^2-35x

Step-by-step explanation:

Firstly, you want to combine the "x"s in the (5x*x^2) and the (5x*3x). Once you have that (you will get 5x^3 and 15x^2), you can move onto the last set of parenthesis. We can get 35x from here. Finally, the last step is to add the correct signs. Our final answer will then be 5x^3+15x^2-35x. I hope this helped and please don't hesitate to reach out with more questions!
