2-2N=3N+17
help plz thank you
Answer:
-3 = N
Step-by-step explanation:
2-2N=3N+17
Add 2N to each side
2-2N+2N=3N+2N+17
2 = 5N +17
Subtract 17 from each side
2-17 = 5N+17-17
-15 = 5N
Divide each side by 5
-15/5 = 5N/5
-3 = N
Answer:
N= -3
Step-by-step explanation:
First, bring 3N on to the left side by subtracting 3N with 2N
2-2N-3N=17
Then, move 2 to the right side by subtracting 17 and 2: -2N-3N= 17-2
Solving the like terms gives us -5N= 15
N= 15/-5
N= -3

Solve. Suppose that 1,000 students took a math examination wherein the maximum score that they can obtain is 100. Their average score is 70 with a standard of the deviation of 5. How many of the students obtained a score from 70 to 95?
Answer:
prolly like 689
Step-by-step explanation:
As per the given data, approximately 499 of the 1,000 students obtained a score from 70 to 95.
What is z-score?A standardized score is an example of a z-score. A z-score is a measure of how far a data point is from the mean in a distribution.
To solve this problem, we need to calculate the number of students who obtained a score from 70 to 95.
First, we need to calculate the z-scores for these two scores using the formula:
z = (score - mean) / standard deviation
For a score of 70:
z = (70 - 70) / 5 = 0
For a score of 95:
z = (95 - 70) / 5 = 5
Next, we need to find the area under the standard normal distribution curve between these two z-scores using a standard normal distribution table or calculator.
The area between z = 0 and z = 5 is approximately 0.499, or 49.9%.
Finally, we can calculate the number of students who obtained a score from 70 to 95 by multiplying this proportion by the total number of students:
Number of students = proportion x total number of students
Number of students = 0.499 x 1000
Number of students ≈ 499
Therefore, approximately 499 of the 1,000 students obtained a score from 70 to 95.

Please do correctly! I will mark you Brainliest!
Answer:
3(4+√2)
Step-by-step explanation:
Here we need to find the perimeter of the given figure. Here the given figure is made from a triangle and a square. The side lenght of the square is 3. We need to find the hypontenuse of the triangle in order to find Perimeter .
• Using Pythagoras Theorem :-
⇒ h² = p² + b²
⇒ h² = 3² + 3²
⇒ h² = 9 + 9
⇒ h² = 18
⇒ h = √[ 9 × 2 ]
⇒ h = 3√2 .
Therefore the perimeter will be ,
⇒ P = 3√2 + 3 + 3 + 3 + 3
⇒ P = 3√2 + 12
⇒ P = 3( 4 + √2)
Hence the perimeter of the figure is 3(4+√2) .The volume of a rectangular prism is 12 cubic inches. One of the dimensions of the prism is a fraction. What could the dimensions of the prism be? Give two possible answers.

In the triangle above, the measure of A is 66°, and the measure of B is 68°. What is the measure of C?
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°
