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.

Can someone please help me find the measure of the exterior angle.
Answer:
X=128°
Step-by-step explanation:
Because an exterior angle of a triangle is equal to of the two opposite interior angle.
The sum of the exterior and interior angle is equal to 180°
In this case the part marked red = 90° because is a right angled triangle.
90+38=128
180- 128=52
180- 52=128
x=128.
Answer:
128 degrees.
Step-by-step explanation:
Simply add 38 degrees with 90 degrees.

If a number becomes 2.5 times smaller, by what percent was it decreased?
Answer: 40%
Step-by-step explanation: 1 Divided by 2.5 is 0.4, or 40%.
The number decreased by 150%
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here a number becomes 2.5 times smaller than let the number be x then the value of the number the decrease is = x - 2.5x
= -1.5x
Thus the percentage decrease is = -1.5x/x × 100
= - 150%
Hence, The number decreased by 150%

What is 4x + 10 = -26
Answer:
x = -9
Step-by-step explanation:
I'm assuming you're looking for X.
So first, you'll want to subtract 10 from both sides of the equation.
4x + 10 = -26
- 10 | -10
4x = -36
Then from there, you'll want to divide by 4. This allows us to get x by itself.
4x = -36
/4 | /4
x = -9
The value of 'x' is -9 in the given equation.
To solve the equation 4x + 10 = -26, follow these steps:
Step 1: Isolate the variable term by subtracting 10 from both sides of the equation.
4x + 10 - 10 = -26 - 10
4x = -36
Step 2: Solve for 'x' by dividing both sides of the equation by 4.
4x / 4 = -36 / 4
x = -9
So, the value of 'x' is -9.
