Answer:

0, 1, -1

Step-by-step explanation:

7x³ - 7x = 0

=> x(7x² - 7) = 0

=> 7x(x² - 1) = 0

=> x(x² - 1) = 0

=> x(x+1)(x-1) =0

=> x = 0 or x = -1 or x = 1

The value of x is 20.

The value of y is 30.

The value of x is 30.

The value of y is 4.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

3,

The triangle is an equilateral triangle.

Value of all the angles = 60°

All sides are equal.

Now,

46 = 16 + y

y = 46 - 16

y = 30

Now,

The sum of the three angles of the triangle is 180 degrees.

80 + 60 + (60 - x) = 180

140 + 60 - x = 180

200 - 180 = x  

x = 20

4.

There is an equilateral triangle.

5y = 20

y = 4

There is an isosceles triangle.

Where two sides are equal and the angle opposite to the equal sides are also equal.

This means,

(180 - 60) + x + x = 180

120 + 2x = 180

2x = 180 - 120

x = 60/2

x = 30

Thus,

3.

The value of x and y is 20 and 30.

4.

The value of x and y is 30 and 4.

Step-by-step explanation:

both side angles are 45°, that makes the triangle an isoceles triangle (both legs are equally long).

therefore, v = 7.

Pythagoras gives us

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90° angle), a and b being the legs.

in our case

u² = 7² + 7² = 49 × 2

u = sqrt(49 × 2) = 7 × sqrt(2)

Answer:124

Step-by-step explanation:

its right

The system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given:

Amir spent a total of $53.75 on breakfast sandwiches and bagels

Each breakfast sandwich costs $4.25, and each bagel costs $2.00

Calculate the equation as shown below,

4.25x + 2y = 53.75

Here, y = number of bangles and x = number of sandwiches,

y = x + 5

Solve the equation to get the values,

x  = 7 and y = 7 + 5 = 12

Therefore, the system of equations is 4.25x + 2y = 53.75, y = x + 5, and the number of bangles and breakfast sandwiches Amir bought is 12 and 7 respectively.

the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean

Data dispersion in regard to the mean is quantified by a standard deviation, or. Data are said to be more closely grouped around the mean when the standard deviation is low and more dispersed when the standard deviation is high.

The confidence interval of the proportion of people who order a burger at the Burger, using a 95% confidence level is; (0.817, 0.879)

A confidence interval is the likelihood of the parameters of a population to be found between a value set within a specified proportion of time.

The confidence interval at the 95% confidence level of a population proportion can be found by using the following formula;

[tex]\hat p = \pm z^* \cdot \sqrt{\dfrac{\hat {p} \cdot (1 - \hat{p})}{n} }[/tex]

Where:

z = The standard normal distribution value that reflects the 95% confidence level

[tex]\hat p[/tex] = The proportion of the sample that ordered burger

n = The size of the sample in the survey

The z-score at the 95% confidence level is about 1.96

[tex]\hat {p} = \dfrac{424}{500} =0.848[/tex]

Plugging in the values of z, [tex]\hat{p}[/tex], and n, the  confidence interval is therefore;

[tex]0.848 \pm 1.96 \times \sqrt{\dfrac{0.848\times (1 - 0.848)}{600} }[/tex]

Resolving the ± into plus and minus, we get;

[tex]0.848 + 1.96 \times \sqrt{\dfrac{0.848\times (1 - 0.848)}{600} } \approx 0.879[/tex]

[tex]0.848 - 1.96 \times \sqrt{\dfrac{0.848\times (1 - 0.848)}{600} } \approx 0.817[/tex]

Based on the definition of complementary angles, the value of d is: 10.

Complementary angles can be described as two angles that have a sum of 90 degrees when added together.

Given that the two angles, 24° and (7d - 4)°, are complementary angles, it implies that their sum will give a measure of 90°. Therefore, to find the value of d, the following equation would be created based on the definition of complementary angles:

24 + (7d - 4) = 90

Open the parentheses:

24 + 7d - 4 = 90

Combine like terms:

7d + 20 = 90

Subtract 20 from both sides

7d + 20 - 20 = 90 - 20

7d = 70

Divide both sides by 7

7d/7 = 70/7

d = 10

The value of d is: 10.
