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.

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.

Step-by-step explanation:

Answer:

the initial investment is $1,200

Step-by-step explanation:

The computation of the initial investment is shown below:

As we know that

Let us assume the investment be 100

So, the investment increased be 72

So,

Simple interest = Principal × rate of interest × time period

72 = Principal × 3% × 2 years

So, the principal is

= 72 ÷ 3% × 2

= $1,200

hence, the initial investment is $1,200

angle 5 = 81°

angle 6 = 99°

angle 7 = 81°

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:

N=15

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)

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°
