6.) Lamb's-quarter weed is a common weed that inhibits the growth of corn. In a study, corn was planted at the same rate across 16 plots of land, and then the plots were weeded at different rates to allow a specific number of weeds to grow. No weeds other than lamb's-quarter were allowed to grow at all. The study aimed to see how much corn yield was affected by the presence of increased number of lamb's- quarter weeds per meter. When the study is finished, the data is found to have a moderately strong negative correlation of -0.72. Calculate the value of the variance.
O A. 72%
O B. 100%
O C. 51.8%
O D. 28% ​

Answer:

It would be 86/9 because you would need to make it improper

Step-by-step explanation:

Answer: its still going to get 9 5/9 or 86/9 theres no common divisor for them

Step-by-step explanation:

Answer:

x=3.2

Step-by-step explanation:

4(6 – x) + 4 = 2 (3x + 1) – 6

24 - 4x + 4 = 6x + 2 - 6

28 - 4x = 6x -4

-4x - 6x = - 4 - 28

-10x = - 32

divide both sides

x = 16/5 or x = 3.2

hope this helps :)

Parallel lines are defined to be two lines that will never intersect even when they go on infinitely. Think of it like railroad tracks. The rails must always be parallel, or the train will gets stuck. By observing lines L and M, you'll notice both lines make perfect railroad tracks, and they will never intersect. These lines are parallel.

Answer:

Many situations will call for you to round decimals to the nearest tenth to make the number easier to work with. Once you understand how to find the tenths and hundredths place, the process is very similar to rounding whole numbers.

Answer:

6

Step-by-step explanation:

The way you wrote it, it is already rounded.....

The value I remember for pi is 3.14159. This is rounded to the nearest 10-thousandth. Another way of saying the same thing is that it is "rounded to 5 decimal places".

pi--rounded off in decreasing precision:

3.14159

3.1416

3.142

3.14

3.1

3

Watch out for a trap in rounding:

Suppose I start with 5.49. To the nearest 10th, it would be 5.5. To the nearest whole digit, it is 5, not 6. If the original number were 5.51, then rounded to the nearest whole digit would be 6.

-10 :)

Hey champ! Here's the 'splination!

equation: 50-5x=100

50=-5x. (subtract 50 from both sides)

-10=x (divide both sides by -5)

Answer:

It's 10 times larger.

Step-by-step explanation:

If you just have 500,000, and the other one is 50,000, That means 50,000 x 10 is 500,000.

Step-by-step explanation:

Answer:

37.875 lb (37 lb 14 oz)

Step-by-step explanation:

(There are 16 oz in 1 lb)

68 lb = (68 x 16 =) 1,088 oz

1,088 oz + 13 oz = 1,101 oz

30 lb = (30 x 16 =) 480 oz

480 oz + 15 oz = 495 oz

1,101 oz - 495 oz = 606 oz = (606 oz ÷ 16 =) 37.875 lb

Final answer:

37.875 lb (37 lb 14 oz)

Step-by-step explanation:

Answer:

The correct option is f.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

It is provided that an experimenter flips a coin 100 times and gets 58 heads.

That is the sample proportion of heads is, [tex]\hat p=0.58[/tex].

The critical value of z for 90% confidence level is, z = 1.645.

*Use a z-table.

Compute the 90% confidence interval for the probability of flipping a head with this coin as follows:

[tex]CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]

     [tex]=0.58\pm 1.645\cdot\sqrt{\frac{0.58\times(1-0.58)}{100}}\\\\=0.58\pm 0.0812\\\\=(0.4988, 0.6612)\\\\\approx (0.499, 0.661)[/tex]

Thus, the 90% confidence interval for the probability of flipping a head with this coin is (0.499, 0.661).

The correct option is f.

Step-by-step explanation:

the answer would be in the y=m(m=slope of the line)x + b( the y intercept) so it works be

y=3x+-3

Answer:

5.7 units

Step-by-step explanation:

The distance from point P to QS is the distance from point P (1, 1) to the point of interception R(-3, 5).

Use distance formula to calculate distance between P and R:

[tex] PR = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] P (1, 1) = (x_1, y_1) [/tex]

[tex] R(-3, 5) = (x_2, y_2) [/tex]

Plug in the values into the formula.

[tex] PR = \sqrt{(-3 - 1)^2 + (5 - 1)^2} [/tex]

[tex] PR = \sqrt{(-4)^2 + (4)^2} [/tex]

[tex] PR = \sqrt{16 + 16} [/tex]

[tex] PR = \sqrt{32} [/tex]

[tex] PR = 5.7 units [/tex] (to nearest tenth)

Step-by-step explanation:

Answer:

[tex]\frac{1}{2}[/tex] blocks

Step-by-step explanation:

If it takes 15 minutes to walk 7 1/2 blocks, it should be 15:17[tex]\frac{1}{2}[/tex]

The left side is minutes and the right side is the number of blocks

15:17[tex]\frac{1}{2}[/tex]

 1: ?  Since we are figuring out how many blocks he can walk in a minute, the left side is 1 and the right side is a question mark because we have not figured it out yet.

15: 17 [tex]\frac{1}{2}[/tex]    Divide by 15 on both sides because that is the "distance" from 15 to1

 1 : ?

1: [tex]\frac{1}{2}[/tex]

So the answer is [tex]\frac{1}{2}[/tex]
