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?
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.
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.

Solve 4/9 plus x =7/9 x =
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.

Quadrilateral ABCD is rotated 90° about the origin. Select the graph that shows this rotation.
The correct graph that shows this rotation is shown in Option 3.
What is Translation?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.

A rectangle has sides that are 10 m, 10m, 5m, and 5 m. What is the rectangle’s length?
5m
20 m
10 m
30 m
The way the question is worded is a little confusing.
I think I would say 10m. It could be 5m, but usually they list length first, then width. The perimeter, the whole distance around the outside, is 30 m (10 + 10 + 5 +5)
The length of the rectangle will be 10 m.
What is a rectangle?A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
Given that, a rectangle has sides that are 10 m, 10 m, 5 m, and 5 m.
We need to find the length of the rectangle,
We have the dimensions 5 m x 10 m,
Lengths in a rectangle tells that how much the rectangle is long and the width tells how much the width tells about the breadth of the rectangle,
So, we can say that,
Length = 10 m
Width = 5 m
Hence, the length of the rectangle is 10 m.

Construct an isosceles triangle with the given base and the opposite angle to the base.
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.

the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)
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!
Side Note:
I know the format is terrible, but the answer is right so please bear with me :)I know the person asking this question asked it a year ago so i'm just answering it for future usersIf i'm guessing correctly, this question originated from RSM, and I found it googling rsm problems, and my answer is correct in RSM, so if you have this same question on your RSM homework, I promise you it's rightIf you got this from RSM homework, and you have other questions about the same types, like 7abcdegi, comment, because I have those answers tooIf you have any questions about this answer, also comment, I would love to helpIf the user who asked this question is still active, I would really appreciate brainliest if you think this deserves itHope this helps!!

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]
