The value of x from the figure shown is 2.19

According to the Pythagoras theorem, the square of the hypotenuse is equivalent to the sum of the square of other two sides.

From the given diagram, the expression below is true;

6^2 = 3^2 + (3+x)^2

Determine the value of x

36 = 9 + (9+6x + x^2)

36 = 18 +6x+x^2

x^2 + 6x - 18 = 0

On factorizing, the value of x is expressed as;

x = -3 + 3√3
x = -3 + 3(1.732)

x = 2.19

Hence the value of x from the figure shown is 2.19

The total proportion of shirts between two prices is 0.9431, which is obtained using the knowledge of proportion and statistics.

What is proportion?

In mathematics, a proportion is defined as the comparison between two numerical quantities. If both possess the same nature, they are called directly proportional, or else called inversely proportional.

Calculation of the proportion based on the problem

The mean and standard deviation are given to be 45 and 5 respectively

Calculate standard normal variate using the formula, z = (x - 45) / 5

Taking x = 37, we get,

z1 = (37 - 45) / 5

= -1.6

Using the z table, we get the value, z1 = 0.0548

Now, taking x = 59.35, we get,

z2 = (59.35 - 45) / 5

= 2.87

Using the z table, we get the value, z2 = 0.9979

The proportion between two prices is given by z = z2 - z1

z = 0.9979 - 0.0548

= 0.9431

Hence, the proportion of shirts between the two prices is 0.9431.

Step-by-step explanation:

The y-intercept is -5 so the line hits the y-axis at -5. The slope of the line is 1/2 so the line goes up one and to the right two each time.

The numbers from least to greatest are -

square root of 7, 2.8, square root of 7 and 4.6.

Descending pattern is defined as it is when numbers (and other objects) are arranged in descending order from the largest to the smallest numbers.

Ascending is defined like when numbers (or even other items) are positioned in ascending order from the smallest to the largest numbers.

We have the numbers provided as;

4.6, 2.8, square root of 17 and the square root of 7.

Then,

square root of 7

√7 = 2.645, and

square root of 17

√17 = 4.123

Thus, the given series becomes;

4.6, 2.8, 4.123, 2.645.

Now, arranging them according to ascending order (least to greatest).

2.645, 4.123, 2.8 and 4.6.

Therefore, the series becomes; square root of 7, 2.8, square root of 7 and 4.6.

After converting all the given units of length into meters we get,

[tex]108 in = 2.7432 m\\108 ft = 32.9184 m\\12 ft = 3.6576m\\1 yd= 0.9144m[/tex]

As per the question statement, we are supposed to convert these given units of length into meters i.e., 108 inches, 108 feet, 12 feet, 1 yard.

We know

[tex]1 foot = 12 inches[/tex]

[tex]1 inch = 2.54 cm\\[/tex]

[tex]12 inches = 2.54*12=30.48 cm\\1 cm = 0.01 m \\30.48 cm = 0.3048 m[/tex]

Therefore, we can infer that 1 foot = 0.3048 m

So,

[tex]108 in = 2.7432 m\\108 ft = 32.9184 m\\12 ft = 3.6576m\\[/tex]

A system of equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.

You can solve a system of equations by the adding or substitution methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.

First, you should convert the text of the question into a math expression. Then,

       5B+3L=92, where B= libretas  and L=lápices.

       2B+6L=56, where B= libretas  and L=lápices.

Therefore,

5B+3L=92 (1)

2B+6L=56  (2)

After that, you should multiply equation(1) by -2. Thus,

-10B-6L=-184(1)

2B+6L=56  (2)

Now, when you sum equations 1 and 2, you  eliminate L . Thus, from this sum, you will have:

-8B=-128

B=128/8

B=16

If B=16, from equation 2, you can find L.

2B+6L=56  (2)

2*16+6L=56

32+6L=56

6L=56-32

6L=24

The claim that a researcher may infer a causal link between variables if one effects another is False.

If a change in one variable's level results in a change in the other variable, then there is a causal relationship between the two variables. Keep in mind that correlation does not always imply causation. Two variables may be linked together without one of them directly contributing to the other's observable behavior.

For instance,

the chart below illustrates the relationship between ice cream sales and temperature. Any business can utilize the concept of causality. As is clear from the graph, there is a correlation between warmer weather and increased sales.

A casual relationship between two variables only exists when one of the variables actually causes the other to exist, which does not appear to be the case here. Instead, since a change in one variable affects the other, this scenario can be thought of as a correlated relationship.

On the number line, It is true to the claim that the solution to the expression 32 + (-17) is 17 units from 32 in the positive direction.

A number line is an illustration of a graded straight line that represents actual numbers. What we call a "number line" is really a horizontal line with regularly spaced number increments. The number line's response format is determined by the numbers it contains.

All possible numbers may be plotted along a line called a number line. Any real number may be represented by a single dot on a number line.

On the number line, we have the negative numbers on the -ve x-axis to the left and they are smaller than the positive numbers to the right, and this is immediately apparent when looking at a number line.

Given that:

= 32 + (-17)

= 32 - 17

= 17

We can therefore conclude that the given expression shows that we are 17 units far away from 32 in the positive x-axis on the number line.
