Solve the equation square root X-6+2 = 6 for the variable. Show each step of your solution process

zhannawk [14.2K]

The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22

A packet of garden seeds contains 250 seeds. The information printed on the packet indicates that the germination rate for this

Westkost [7]

Answer:

Expectation=240

standard deviation=3.098

Step-by-step explanation:

This is a binomial probability function with n=250 and probability of success is 96%

-The expected value is calculated as:

$E(X)=np\\\\=250\times 0.96\\\\=240$

Hence, the expected germination is 240 seeds

b. From a above, we have the value of p=0.96 and n=250.

The standard deviation of germination is therefore calculated using the formula:

$\sigma=\sqrt{np(1-p)}, \ \ \ \\\\=\sqrt{250\times 0.96(1-0.96)}\\\\\\=3.098$

Hence, the standard deviation of germination is 3.098

Describe how you would test a sample of food to show it contains protein.

harkovskaia [24]

Step-by-step explanation:

Iodine test for starch

Method:

Place one spatula of the food sample on a dish or 1 cm3 if the sample is liquid.

Using a dropper, place a few drops of iodine solution onto the food.

Record any change in the colour of the solution.

Starch is detected using iodine solution. This turns blue-black in the presence of starch.

Answer:

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

Given the equation

$6x+y=6$

Writing in the slope-intercept form of the line equation

$y = -6x + 6$

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

$y-y_1=m\left(x-x_1\right)$

$y - (-5) = -6 (x - 2)$

$y+5=-6\left(x-2\right)$

subtract 5 from both sides

$y+5-5=-6\left(x-2\right)-5$

$y=-6x+7$

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$
