Answer:

The weight of an object when the mass is 10 kg

will be 30 N.

Let the weight of an object whose mass is 10 kg

be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

8/10 = 24/x

Cross multiply

8x =24 x 10

8x=240

x = 240/8

x = 30

Therefore, the weight of an object when the mass

is 10 kg will be 30 N.

D, (13, 4.5)

Step-by-step explanation:

(question asked for midpoint so my bad if this isnt what you wanted)

to calculate the median of a vector, you would have to do a simple calculation to get the answer

for the x coordinate, (9 + 17) / 2 would be 13

for the y coordinate, 5 + 4 / 2 would be 4.5

combining those would give you the answer (13, 4.5)

x = 108

y = 36

z = 72

=============================================================

Explanation:

Check out the diagram below. I have added letters of x, y and z in places to help find the values of y and z. Note the triangle on top is isosceles (since a regular polygon has all sides equal; therefore the triangle on top has the top diagonal sides equal).

Before we find either y or z, let's find x.

For any regular polygon, the interior angles are all the same measure. They sum to 180(n-2). In this case, n = 5, so the angles sum to 180(5-2) = 540. Each individual interior angle is 540/n = 540/5 = 108 degrees

x = 108

Another way to find this interior angle is to first find the exterior angle. For any convex polygon (regular or not), the exterior angles always add to 360. When we talk about regular polygons, each individual exterior angle is 360/n. So in this case, we have 360/5 = 72 as one exterior angle. The adjacent interior angle is therefore x = 180-72 = 108. So there are two ways to find the measure of an interior angle.

--------

Referring to the diagram, specifically the isosceles triangle on top, we can see that it has angles of x, y and y. They add to x+y+y = x+2y. Set this equal to 180, plug in x = 108 and solve for y

x+2y = 180

108+2y = 180

2y = 180-108

2y = 72

y = 72/2

y = 36

--------

The bottom most triangle is a congruent copy of the triangle on top. We have another isosceles triangle with the same side lengths as before. This triangle also has x, y and y as mentioned above.

Notice the adjacent angles of y and z in the bottom left corner. They must add to 108 as this was the measure of the interior angle of a regular pentagon. So,

y+z = x

36+z = 108

z = 108-36

z = 72

The formation's height is 31 meters to the closest meter.

In mathematics, height is defined as the vertical distance between an object's top and bottom. It is also referred to as 'altitude.' The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.

Height, altitude, and elevation all refer to the vertical distance between the top and bottom of something or between a base and anything above it. Height is a standard bodily measurement that is commonly measured in feet (ft) + inches (in) in the United States and centimeters (cm) abroad. Because they are length measurements, the SI unit would be meters.

We can use the tangent function to calculate the formation's height, h.

tan ( 36°) = h/43

Here, we have to multiply both sides by 43 we get,

43tan (36°)= h

h=31m

Therefore, the height of the formation to the nearest meter is 31m.

Step-by-step explanation:

The expected value of the machine after 6 years is approximately $4086.

To find the value of the machine after each year, we can use the formula:

Vn = V0 x (1 - r)ⁿ

where Vn is the value of the machine at the end of year n, V0 is the initial value of the machine, r is the depreciation rate (0.20 in this case), and n is the number of years.

For the first year, we have:

V1 = 25000 x (1 - 0.20)¹ = 20000

For the second year, we have:

V2 = 25000 x (1 - 0.20)² = 16000

Continuing this pattern, we find that the value of the machine at the end of the sixth year is:

V6 = 25000 x (1 - 0.20)⁶ = 4085.76

Answer:

First, we need to calculate the total cost of Lisa's and Tracy's lunches before tax and tip.

Lisa's lunch = $6

Tracy's lunch = $7

Total before tax and tip = $6 + $7 = $13

Now we need to add the 5% sales tax:

$13 x 0.05 = $0.65

Total after tax = $13 + $0.65 = $13.65

Finally, we need to add the 15% tip:

$13.65 x 0.15 = $2.05

Total bill = $13.65 + $2.05 = $15.70

Therefore, the total bill, including tax and tip, is $15.70.

Answer:

Step-by-step explanation:

6 + 7 = 13

Now for the sales tax and tip, we need to add 15 and 5 together which is 20. So now we need to multiply 13 times the decimal equivalent of 20%. So, 0.20 x 13 = 2.6

2.6 + 13 = 15.6

The answer is 15.6

The total mass of the paper clips in the box will be C. 2.226 × 10^1

Scientific notation is a method of displaying very large or very small numbers in a more simplified format. We know that entire numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers in the millions place after the decimal required to be represented in a simpler format.

Since the mass of a paper clip is 7.0 x 10−4 mg and a box of paper clips has 3.18 x 104 paper clips, the total mass of the paper clips in the box will be:

= (7.0 × 20^-4) × 3.18 ÷ 10^4)

i belive this is the answer becuase 3 divided by (3/4)

The function composition exists an operation " ∘ " that brings two functions f and g, and has a function h = g ∘ f such that h(x) = g(f(x)).

Let the functions be f(x) = 4x² + 1 and g(x) = x² - 3

The correct answer is (f o g)(x) = 4x⁴ - 96x + 37 and

(g o f)(x) = 16x⁴ + 8x² - 2.

The function composition exists an operation " ∘ " that brings two functions f and g, and has a function h = g ∘ f such that h(x) = g(f(x)). In this operation, the function g exists used for the outcome of applying the function f to x.

Given:

f(x) = 4x² + 1 and g(x) = x² - 3

a) (f o g)(x) = f[g(x)]

f[g(x)] = 4(x² - 3)² + 1

substitute the value of g(x) in the above equation, and we get

    = 4(x⁴ - 24x + 9) + 1

simplifying the above equation

    = 4x⁴ - 96x + 36 + 1

    = 4x⁴ - 96x + 37

(f o g)(x) = 4x⁴ - 96x + 37

b) (g o f)(x) = g[f(x)]

substitute the value of g(x) in the above equation, and we get

g[f(x)] = (4x² + 1)²- 3

      = 16x⁴ + 8x² + 1 - 3

simplifying the above equation

      = 16x⁴ + 8x² - 2

(g o f)(x) = 16x⁴ + 8x² - 2.

Therefore, the correct answer is (f o g)(x) = 4x⁴ - 96x + 37 and

(g o f)(x) = 16x⁴ + 8x² - 2.

1) Option B, which states that the confidence interval size shrank from 0.99 to 0.90, is the right answer.

2) Option D is the best decision. Confidence interval: 0.88

1) Confidence intervals are ranges of estimates for unknown parameters in frequentist statistics. Confidence intervals are given a confidence level. The most common level is 95%, but other levels, such as 90% or 99%, may be used as well.

Therefore, option B is the correct choice, which states that the confidence interval size decreased from 0.99 to 0.90

2) Probability is another word for confidence in statistics. An estimate that falls between the upper and lower values of a confidence interval, such as one constructed with a 95% level of confidence, is 95 out of 100 times likely to be accurate.

It can be calculated as:

t critical value 0.12 (two tail) = 1.62797
