7. An administrator surveys a random sample of 48 out of 900 middle school students. Using the
survey results, the administrator predicts that 225 students are in favor of the new dress code.
How many of the 48 students surveyed were in favor of the new dress code?

Answers

Answer 1

Answer:

12 students

Step-by-step explanation:

225 is 25% of 900 and 25% of 48 is 12.

Answer 2

The number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

An administrator surveys a random sample of 48 out of 900 middle school students.

Using the survey results, the administrator predicts that 225 students are in favor of the new dress code.

The proportion of sample = 225/900

= 0.25

In percent sample:

= 0.25x100 %

= 25%

A number of students surveyed were in favor of the new dress code:

= 25% of 48

= (25x48)/100

= 1200/100

= 12

Thus, the number of students is 12 that is surveyed were in favor of the new dress code the answer is 12.

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees

Answers

Answer:

This is the correct way to set up the equation:

9x + 88 + 6x + 182 = 180

I'm going to move some things around so we can combine like terms. It now reads:

9x + 6x + 88 + 182 = 180

9x + 6x = 15x, so the equation now reads:

15x + 88 + 182 = 180

88 + 182 = 270, so the equation reads:

15x + 270 = 180

Subtract the 270 from both sides. 180 - 270 is -90:

15x = -90

Divide both sides by 15. -90 divided by 15 = -6:

x = -6

Now we can substitute -6 back into the separate equations.

9(-6) + 88 = ?

9 times -6 is -54. -54 + 88 = 34.

6(-6) + 182 = ?

6 times -6 = -36. -36 + 182 = 146

Now we can add 34 and 146 together.

34 + 146 = 180

You roll a die and flip a coin. What is the probability of NOT rolling a 4 on the die and flipping a heads on the coin?

Answers

Answer:

The probability of not rolling a 4 on the die and flipping heads on the coin is 5/6.

Step-by-step explanation:

Assuming the die is 6-sided, the probability of not rolling a 4 is 5/6, because all other possible values other than 4 can be rolled to make the probability true. 5/6

The probability of flipping heads on the coin is 1/2, considering there are 2 sides on the coin, heads, and tails.

To find the probability of both these events occurring, multiply both the probabilities together. (5/6) * (1/2) = 5/12.

Tell whether the difference between two negative integers is always, sometimes, or never positive. The difference between two negative integers is (blank) positive.

Answer:

Step-by-step explanation:

The difference is sometimes positive. If the second number is smaller than the first, then the result will be positive..

28.3

Step-by-step explanation:

Use the Pythagorean theorem a^2 + b^2 = c^2

x is a, 17 is b, and 33 is c

x^2 + 17^2 = 33^2

Simplify:

x^2 + 289 = 1089

Subtract 289 from both sides:

x^2 = 800

Square root both sides:

x = √800

√800 is 28.28427, or 28.3

The atmosphere is composed of different levels. The first level, called troposphere, is the nearest to the Earth, about 11 km thick. Most clouds and weather are found in this layer. Next is the stratosphere which is about 11-48 km above the Earths surface. In it is the ozone layer which absorbs most of the harmful ultraviolet radiation from the sun. The mesosphere is above the stratosphere in which the atmosphere is very rarefied, and the temperature decreases with altitude. The fourth layer is the thermosphere which starts at about 55 km. The temperature is so hot that it cannot be measured by the thermometer. Temperature maybe a thousand degrees high. The second to the last is the exosphere, the region beyond the thermosphere, Finally, the ionosphere overlaps the other layers from above the Earth. The air is ionized by the Suns ultraviolet rays. These ionized layers affect the transmittance and reflectance of radio waves. All in all, there are six levels of the Earths atmosphere.1. What kind of paragraph is it? 2.
