Hooke’s law states that the distance that a spring is stretched by hanging object varies directly as the mass of the object. If the distance is 20 cm when the mass is 3 kg, what is the distance when the mass is 5 kg?

Answer:

B.

Step-by-step explanation:

Answer:

48 inches

Step-by-step explanation:

Given:

A square and an equilateral triangle have the same perimeter

Each side of the triangle is 4 inches longer than each side of the square.

What to find:

What is the perimeter of the square =?

Solution:

Let the side of the square be  

Then the side of the triangle will be  

The Perimeter of square = Perimeter of an equilateral triangle

=  

Subtracting both sides by  

side of the square,  = 12 inches

side of triangle will be , 12 + 4 = 16 inches

Now, the perimeter of the square =  

Therefore, the perimeter of the square is 48 inches.

divide the volume value by 8

Answer:

y + 5 = -3(x + 8)

General Formulas and Concepts:

Point-Slope Form: y - y₁ = m(x - x₁)

x₁ - x coordinate

y₁ - y coordinate

m - slope

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Parallel Lines always have the same slope but different y-intercepts.

Step-by-step explanation:

Step 1: Define

Given (Parallel Line): y = -3x + 9

Point (-8, -5)

Step 2: Find variables

Slope m of parallel lines = -3

Step 3: Find parallel line equation

y₁ = -5

x₁ = -8

m = -3

y + 5 = -3(x + 8)

Answer:

FALSE

Step-by-step explanation:

The statement is false the arithmetic sequence should have a common difference.

The sequence in which every next number is the addition of the constant quantity in the series is termed the arithmetic progression

An example of the arithmetic sequence is,

2,5,8,11,.........

The common difference is 5 - 2 = 3.

When there is a constant between the two successive numbers in the series then it is called a geometric series. In other words, every next term is multiplied by that constant term to form a geometric progression.

An example of the geometric sequence is,

2,4,8,16,.............

The common ratio is 4 / 2 = 2

Therefore, the statement is false the arithmetic sequence should have a common difference.

Answer: 11!

Step-by-step explanation:

Answer:

Explained below.

Step-by-step explanation:

The probability density function of lifetime in months of a transistor in a certain application is:

[tex]f(x)=0.4\cdot e^{-0.4x};x>0[/tex]

The probability density function suggests that the random variable X follows a exponential function with parameter λ = 0.4.

(a)

Compute the mean lifetime as follows:

[tex]\mu=\frac{1}{\lambda}=\frac{1}{0.40}=2.5[/tex]

Thus, the mean lifetime is 2.5 months.

(b)

Compute the standard deviation of the lifetimes as follows:

[tex]\sigma=\sqrt{\frac{1}{\lambda^{2}}}=\sqrt{\frac{1}{0.40^{2}}}=2.5[/tex]

Thus, the standard deviation of the lifetimes is 2.5 months.

(c)

The cumulative distribution function of the lifetime is:

[tex]CDF=1-e^{-0.40x}[/tex]

(d)

Compute the probability that the lifetime will be less than 6 months as follows:

[tex]P(X<6)=\int\limits^{6}_{0} {0.40\cdot e^{-0.40x}} \, dx[/tex]

               [tex]=0.40\times [\frac{e^{-0.40x}}{-0.40}]^{6}_{0}\\\\=-1\times [e^{-0.40\times6}-e^{-0.40\times0}]\\\\=-0.090718+1\\\\=0.909282\\\\\approx 0.9093[/tex]

Thus, the probability that the lifetime will be less than 6 months is 0.9093.

(e)

Compute the 60th percentile of the lifetime as follows:

[tex]P(X<x)=0.60\\\\\int\limits^{x}_{0} {0.40\cdot e^{-0.40x}} \, dx=0.60\\\\0.40\times [\frac{e^{-0.40x}}{-0.40}]^{x}_{0}=0.60\\\\-1\times [e^{-0.40\times x}-e^{-0.40\times0}]=0.60\\\\1-e^{-0.40x}=0.60\\\\e^{-0.40x}=0.40\\\\-0.40x=\ln(0.40)\\\\-0.40x=-0.916291\\\\x=2.2907275\\\\x\approx 2.3[/tex]

Thus, the 60th percentile of the lifetime is 2.3 months.

Answer:

It is an overestimate.

Step-by-step explanation:

If you round 5 to the nearest 10, you get ten. If you round 11.45, to the nearest ten, you also get 10. Your estimate is 100. Your real answer is 57.25.

Answer:

Let b = profit on a blue car

w = profit on a white car

r = profit on a red car

b = w + 10 (1)

r = w - 7 (2)

2r = b -2

2r-b= -2 (3)

Subtract eq. (2) by 2q. (1)

r - b = 0 - 7 - 10

r - b = -17 (4)

Subtract eq. (3) by eq. (4)

r - 0 = -2 - (-17)

r = 15

in eq (2)

r = w - 7

15 = w - 7

w = 22

in eq (1)

b = w + 10

b = 22 + 10

b = 32
