Answer:

x=4

Explanation:

1.5(4+x)−3=4.5(x−2)

Step 1: Simplify both sides of the equation.

1.5(4+x)−3=4.5(x−2)

(1.5)(4)+(1.5)(x)+−3=(4.5)(x)+(4.5)(−2)(Distribute)

6+1.5x+−3=4.5x+−9

(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)

1.5x+3=4.5x−9

Step 2: Subtract 4.5x from both sides.

1.5x+3−4.5x=4.5x−9−4.5x

−3x+3=−9

Step 3: Subtract 3 from both sides.

−3x+3−3=−9−3

−3x=−12

Step 4: Divide both sides by -3.

−3x−3=−12−3

x=4

Each of 6 samples has a different standard deviation. How many of the 6

ivann1987 [24]

The number of six samples that could belong to the same population is equivalent to six.

Option A is the correct answer.

<h3>What is the standard deviation?</h3>

The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.

The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.

Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

The graph of y=f(x) is shown above. Which of the following could be the graph of y=f′′(x)?.

AfilCa [17]

The true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).

Start by calculating the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

So, we have:

$m = \frac{3-0}{0--5}$

Simplify

$m = \frac{3}{5}$

The equation of the line is then calculated as:

$y = m(x -x_1) + y_1$

This gives

$y = \frac 35(x -0) + 3$

Open bracket

$y = \frac 35x + 3$

Express y as a function of x

$f(x) = \frac 35x + 3$

Hence, the true statement about the graph of f(x) is $f(x) = \frac 35x + 3$

the volumes of two similar solids are 210 m3 and 1,680 m3. the surface area of the larger solid is 856 m2. what is the surface a

kolezko [41]

The surface area of the smaller solid is found to be 214 square meters.

<h3>What is Surface area?</h3>

The surface area is given as the sum of the area of all the faces of a three-dimensional object.

The same shape has equivalent ratio of the surface area to volume. It is given as:

$\rm \dfrac{\sqrt{area_1}}{\sqrt{area_2}}=\dfrac{\sqrt[3]{Volume_1} }{\sqrt[3]{Volume_2} }$

On considering the power of 6 at both the sides of the equation:

$\rm \dfrac{area_1^2}{area_2^2}=\dfrac{volume_1}{volume_2}$

Considering area 1 and volume 1 for the larger solid, and area 2 and volume 2 for the smaller solid, substituting the values give:

$\rm\dfrac{(856\;m^2)^3}{(area_^2)^3}=\dfrac{(1680\;m^3)^2}{(210\;m^3)^2}$

By solving the above equation, the area of the smaller solid is found as 214 square meters. Thus, option B is correct.

President Reagan’s new approach to the Cold War reveal about his foreign-policy strategy is:

<u>C. He wanted to work for peace from a position of military strength. </u>

<u />

The Cold War was a period in history between the United States and Russia (then known as the Soviet Union) where there were conflicts which led to trade embargoes, diplomatic issues and threats of war.

The two leaders of America and the Soviet Union respectively, President Reagan and Comrade Gorbachev were engaged in war of words and President Reagan tried to make peace and evoid conflict, even though the United States were stronger from a military perspective

Therefore, the correct answer is option C
