Answer:

Step-by-step explanation:

subtract 160 from both sides, you get -178, 2d divided by -178 is -89 so you get d=-89.

Answer:

d = -89

Step-by-step explanation:

2d + 160 = -18

Isolate the variable, d. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 160 from both sides:

2d + 160 (-160) = -18 (-160)

2d = -18 - 160

2d = -178

Divide 2 from both sides:

(2d)/2 = (-178)/2

d = -178/2

d = -89

d = -89 is your answer.

Between 5 to 12

There can be 6,7,8,9,10,11

And we can merely calculate that 7 is the one and only factor of 28 according to the question.

So,

There are 7 plants in each row,

A recent study asked U. S. Adults to name 10 historic events that occurred during their lifetime that have had the greatest impa

Nadusha1986 [10]

Using the z-distribution, as we are working with a proportion, it is found that the 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

In this problem, the parameters are:

$z = 2.575, n = 2000, \pi = 0.77$

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 - 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7458$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.77 + 2.575\sqrt{\frac{0.77(0.23)}{2000}} = 0.7942$

The 99% confidence interval for the proportion of all U. S. Adults who would include the 9/11 attacks on their list of 10 historic events is (0.7458, 0.7942). It means that we are 99% sure that the true proportion for all U.S. adults is between these two bounds.
