Answer:

Present-day cells evolved from a common prokaryotic ancestor along three lines of descent, giving rise to archaebacteria, eubacteria, and eukaryotes.

Changed the composition of the oceans. Most of the iron was precipitated out by early life.

Changed the composition of the atmosphere.  Oxygen became available in abundance.

Answer:

200

Step-by-step explanation:

If the equation is T-7p=150, and 1550 tickets are sold, T would be equal to 1550. So the equation becomes 1550-7p=150. Add 150 to both sides to get 1400-7p=0. then add 7p to both sides to get 1400=7p. Divide by 7 to get 200=p

Answer:

4/6=0.67  1/3=0.3

Step-by-step explanation:

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

The profit on a blue car is $32

Step-by-step explanation:

The answer is 10

Step-by-step explanation:

you would the Pythagorean theorem, which is: A squared plus B squared equals C squared. C is always the longer side, also known as the hypotenuse and A and B ae the legs, or the two shorter sides.

Answer:

x = 10

Step-by-step explanation:

8^2+ 6^2 = c^2

64 + 36 = 100

Then square root 100

so x=10

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:

Hi! The answer is actually C. 3

Step-by-step explanation:

Based on the number of exemptions claimed by Selina and her biweekly gross pay, her state tax will be $16.80.

Here, we have,

given that,

from the given information, we get,

Selina is to pay 21% of her federal taxes.

Seeing as she claims a single exemption and falls in the $840 to $860 bracket, the table shows that her federal tax contribution would be $80.

State taxes are therefore:

= 80 x 21%

= $16.80

#SPJ7

Answer:

20

Step-by-step explanation:

Since 0.454 kg = 1 pound,

         0.5675 kg = [tex]\frac{0.5675}{0.454}[/tex] pound = 1.25 pounds= (1.25 * 16) ounces = 20 (ounces)

Answer:

0.5675

Step-by-step explanation:

16/0.454 = x/0.5675...16 oz to 0.454 kg = x oz to 0.5675 kg

cross multiply

0.454x = 16(0.5675)

0.454x = 9.08

x = 9.08/0.454

x = 20.....20 oz are in 0.5675 kg

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.

Answer:

y = 28.1739x² + 45.6478x + 617.4879 ;

$3891.36

Step-by-step explanation:

Given the data above :

We can employ an online quadratic model calculator to create a quadratic model of the data:

Year(t) ____0 ____1 ____2 ____3 ____4 ____5 (P)-603.46_695.39_871.96_972.35_1224.53_1571.52

The quadratic function obtained is :

y = 28.1739x² + 45.6478x + 617.4879

Using the model ; the price of gold in 2016 will be :

X = 2016 = 10 years (2016 - 2006)

y = 28.1739(10)^2 + 45.6478(10) + 617.4879 = 3891.3559

Hence, the predicted price of gold in 2016 using the model will be $3891.36

Answer:

y=  1/4 x - 6

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:

x = -12/7

Step-by-step explanation:

Answer:

[tex]\frac{3}{5}\left(15x-20\right)=-6x+4\left(x-6\right)[/tex]

[tex]9x-12=-6x+4x-24[/tex]

[tex]9x-12=-2x-24[/tex]

[tex]9x-12+12=-2x-24+12[/tex]

[tex]9x=-2x-12[/tex]

[tex]9x+2x=-2x-12+2x[/tex]

[tex]11x=-12[/tex]

[tex]\frac{11x}{11}=\frac{-12}{11}[/tex]

[tex]x=-\frac{12}{11}[/tex]  or  [tex]x=-1.090[/tex]
