Suppose a sample of 313 tankers is drawn. Of these ships, 235 did not have spills. Using the data, estimate the proportion of oil tankers that had spills.

Answer:

Step-by-step explanation:

for number 8 we have to use the equation πr^2, so plugging 9 into the equation would give us π(9^2). squaring the 9 gives us 81, and 81 times π equals ~25.

for number 9 we need to use the same equation, πr^2 to find the area, but since we are given the diameter we do not need to use r^2. Instead, we can use π(106) which gives us 333.

tep explanation:

Answer:

f(x)=2x^2+4x+6

f(x)=2(x^2+2x)+6

f(x)+?=2(x^2+2x+?)+6

f(x)+?=2(x^2+2x+1)+6

f(x)+2x1=2(x^2+2x+?)+6

f(x)+2=2(x^2+2x+1)+6

f(x)=2(x+1)^2+6-2

f(x)=2(x+1)^2+4

Answer:

f(x)=2(x+1)^2+4

Step-by-step explanation:

The first missing quantity is force due to gravity, and it is 215.1 N.

The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.

The force between two masses is determined by applying Newton's law of universal gravitation as shown below;

[tex]F = \frac{GMm}{R^2}[/tex]

where;

The first missing quantity is force due to gravity, and it is calculated as follows;

[tex]F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N[/tex]

The second missing quantity is distance between the statellite and the Earth,

[tex]R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km[/tex]

Answer:

4

Step-by-step explanation:

5x/2 - 1 = 9

add 1 to each side

5x/2 = 10

multiply both sides by 2

5x = 20

divide both sides by 5

x=4

Answer:

x=4

Step-by-step explanation:

5x-2=18 (multiply 9 with 2=18)

5x=18+2 (move 2 to the other side)

5x=20 (add 18 and 2=20)

X=4 (divide 20 and 5 =4)

Which graph indeed?

Eliminate the parameter:

x = t - 4   ⇒   t = x + 4

⇒   y = t² + 5 = (x + 4)² + 5

which is the equation of a parabola with vertex at (-4, 5) and opening upwards, plotted with domain

-1 ≤ t ≤ 2   ⇒   -1 ≤ x + 4 ≤ 2   ⇒   -5 ≤ x ≤ -2

The perimeter of any shape is the length of all the sides added up:

1. For the rectangle

Answer:

Step-by-step explanation:

ax² + bx + c = 0

[tex]x_{1}[/tex] = [tex]\frac{-b - \sqrt{b^2 -4ac} }{2a}[/tex]

[tex]x_{2}[/tex] = [tex]\frac{-b+\sqrt{b^2 -4ac} }{2a}[/tex]

~~~~~~~~~~~~~~~~~~~

x² + 4x - 16 = 0

a = 1 , b = 4 , c = - 16

[tex]x_{1}[/tex] = ( - 4 - [tex]\sqrt{16+64}[/tex] ) ÷ 2 = - 2 - 4√5

[tex]x_{2}[/tex] = - 2 + 4√5
