In sanja primary school the male students are 56 and female students are 44%. What are the total students?​

Answers

Answer:

100

Step-by-step explanation:

Male students take up 100%-44% = 56% of the whole school.

Let x be the total number of students.

56/x = 56%

56/x = 56/100

x = 100

Therefore there are 100 students in total.

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

f ( -1 ) = 2^2/3

f ( 0 ) = 2

f ( 1 ) = 0

f ( 2 ) = -6

f ( 3 ) = -24

Hence , the function is f ( 2 ) = -6

is 369/100 greater than 849/100

Answers

9514 1404 393

Answer:

  no

Step-by-step explanation:

When fractions have the same denominator, you can compare the numerators.

  369 < 849

369/100 is not greater than 849/100

__

Here, you can convert these to decimal numbers and do the comparison in the usual way:

  3.69 < 8.49

The most-significant digits are in the same number place (units), and they are different. The number with the smaller most-significant digit is smaller.

Answer:

no

Step-by-step explanation:

369/100=3.69

849/100=8.49

3.69<8.49

Many states assess the skills of their students in various grades. One of the tests provided by a national association assesses the reading skills of 12th-grade students. In a recent year, the national mean score was 286 and the standard deviation was 38. Assuming that these scores are approximately Normally distributed, N(286, 38), use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.

Answers

Answer:

95% of these scores are between 210 and 362.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 286, Standard deviation = 38

Use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.

This is within 2 standard deviations of the mean. So

286 - 2*38 = 286 - 76 = 210

286 + 2*38 = 286 + 76 = 362

95% of these scores are between 210 and 362.

Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios.

The longest side of the triangle is called the hypotenuse and the other two sides are the legs.

The sine ratio relates the opposite side of an angle of the triangle with the hypotenuse:

[tex]\displaystyle \sin B=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]

Here, the opposite leg to angle B is the side CA=2, and the hypotenuse is the side AB=3, thus:

[tex]\displaystyle \sin \angle B=\frac{2}{3}=0.667[/tex]

Calculating the inverse sine function:

[tex]\angle B=\arcsin (0.667)[/tex]
