Find the range for these data.
Answer:
Hello Love!
All range is in math Is the highest number subtracted by the smallest number so our equation is 15 - 0 = 15
so 15 is our range!

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.

Answer:
You can find X in an equation by doing the opposite operation from both sides. For example, let"s do 5x=25. Since there is multiplication, we can use division to isolate the variable. You would divide both sides by the coifeiccent to get x=5.

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.

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.

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.

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. If a car is driving down Dexter Street, what is the probability that it does not get stopped at either light?
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.
