Answer:

12 students

Step-by-step explanation:

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

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

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.

Answer:

240 people

Step-by-step explanation:

6/20=x/800

800*6=20x

4800=20x

240=x

Therefore, you would expect 240 people to be wearing a hat

1) 5N in one direction and 5N in the other direction will cancel out.

= 0N

2) 3N in one direction and 5N in the same direction will amplify the force. Add them up

= 8N

The probability that it does not get stopped at either light is 14/25.

We have given

Of the two lights on Dexter Street, the probability of the lights being red is 20% for the first light and 30% for the second light.

What is the formula for probability?

The probability of an event A is defined as the ratio of the number of favorable events that occurred in A /total number of events in a sample space

Red light for the first:

The Probability of the red light is 20 out of 100 so you would just find the difference which is 80%.

80/100

Red light for the second:

The Probability of the second red light is 30 out of 100 so you would just find the difference which is 70%.

70/100

The probability of not being stopped at either, multiply across and reduce.

[tex]80/100 * 70/100= 14/25[/tex]

Therefore, The probability that it does not get stopped at either light is 14/25.

Answer:

Proof of Construction: The compass was used as a measuring tool to obtain (and copy) the length of the given segment. Since the given segment and the copy are the same length, the segments are congruent.

Note: You may also think of the length from A to B as being the radius of a circle with center at A. By copying the circle at A', the radii segments will be congruent.

Answer:

r = 62

Step-by-step explanation:

Angles add up to 180 so:

r + r + 56 = 180

2r + 56 = 180

2r = 180 - 56

2r = 124

r = 62

Answer:D

Step-by-step explanation:

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

Answer:

F([tex]\frac{a}{2}[/tex]) = [tex]\frac{24}{a} +\frac{1}{2}\\[/tex]

Step-by-step explanation:

so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have [tex]\frac{12}{\frac{a}{2} }[/tex], if you can't see that, its 12/a/2. In other words, this is 12 ÷ [tex]\frac{a}{2}[/tex] , which you can also format as 12 ·[tex]\frac{2}{a}[/tex], because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!

i did the test

The correct graph that shows this rotation is shown in Option 3.

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

Given that;

Quadrilateral ABCD is rotated 90° about the origin.

Now, We know that;

Condition of 90° clockwise rotation: (x, y) becomes (y,-x)

Hence, For Option 1;

A = (- 2, - 2)

A' = (2, - 2)

Foe option 2;

A = (- 2, - 2)

A' = (2, 2)

Thus, This shows correct graph of rotation.

Answer:

x = 1/3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x + 4/9 = 7/9

Step 2: Subtract 4/9 from both sides.

x + 4/9 - 4/9 = 7/9 - 4/9

x = 1/3

Answer:

x = 1/3 (or) 3/9

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ (4/9) + x = 7/9

Then the value of x will be,

→ (4/9) + x = 7/9

→ x = (7/9) - (4/9)

→ x = (7 - 4)/9

→ x = 3/9

→ [ x = 1/3 ]

Hence, the value of x is 1/3.

Answer:

56 degrees

Step-by-step explanation:

Because DF is a line that makes it 180 degrees we know that the other two angles on that line are are 60 and 64 now we can make an equation:
