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.

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°

GEOMETRY HELP PLEASE!! WILL MARK BRAINLEIST!
Answer:
FHG is 45 degrees
Step-by-step explanation:
For a square, each of the angles at the corners measure 90 degrees
Also, the two diagonals are equal and they bisect one another
Also, the diagonals bisect each of the angles at the corners making each angle lying in each triangle to be 45 degrees, thereby creating 4 isosceles right triangles
For FHG, looking at the triangle FHG, FG and GH are equal lengths as we have an isosceles right triangle
An isosceles right triangle is only possible when the two internal angles asides the right triangle are 45 degrees each
What this mean is that FHG measure is 45 degrees

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

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) .3x+3 solve for x PLLSSSS HELP giving brainliest
