Answer:

x = 35

Step-by-step explanation:

the 3 angles lie on a straight line and sum to 180° , that is

40 + 2x + 30 + 40 = 180

110 + 2x = 180 ( subtract 110 from both sides )

2x = 70 ( divide both sides by 2 )

x = 35

Answer:

y = 3.3x + 20

Step-by-step explanation:

-2/3x +1/5y = 4   y = mx + b

-2/3x + 1/5y = 4

-2/3                -2/3

1/5y = 2/3 + 4

1/5  / 2/3 = 3.3

1/5 / 4 = 20

y = 3.3x + 20

We have shown that the first difference system with scaled feedback by a is equal to the summation formula.

The first difference system with scaled feedback by a is given by:

We can rewrite this equation in terms of summation notation:

By substituting k = i - 1, we can rewrite the summation as:

Now, we can use the property of summation that states that ∑ a[i]b[i] = a ∑ b[i], where a is a constant, to rewrite the equation as:

Since [] is a constant, we can divide both sides of the equation by [] to get:

Finally, we can simplify the left-hand side of the equation to get:

This equation is equivalent to the summation formula given in the question:

Therefore, we have shown that the first difference system with scaled feedback by a is equal to the summation formula.

The scatterplot shows the weakest negative linear correlation is On a graph points are grouped closely together and increase. Option A.

The scatterplot showing the weakest negative linear correlation is the following scatterplot. The dots are scattered along the decreasing trend line. The weakest linear relationship is indicated by a correlation coefficient equal to 0. A positive correlation means that an increase in one variable tends to increase the other variable.

A negative correlation means that as one variable increases the other tends to decrease. Plotted points indicate correlations between variables if any. The scatterplot above is an example of a weak negative correlation. In this graph, y values ​​decrease as x values ​​increase, but the pattern does not resemble a straight line.

Answer:

Step-by-step explanation:

the equation of a circle in standard form is

(x - h )² + (y - k )² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (- 3, 6 ) and r = 2 , then

(x - (- 3) )² + (y - 6)² = 2² , that is

(x + 3)² + (y - 6)² = 4

Step-by-step explanation:

5⁴×5² = 5⁶

10⁶/10³ = 10³

so, we have 5⁶/10³ = 15.625

and in scientific notation we have to write the first digit (which is not 0) in front of the decimal point, and the following digits of the number as pairings after the decimal point, and then indicate a multiplication with a power of 10 to tell us the right position of the decimal point in the plain number.

so, 15.625 as plain number is

1.5625 × 10¹ in scientific notation.

therefore option 1 is correct.

The radian value of 72/8 is given by \(\frac{\pi}{20}\) radian.

We know that 1 = \(\frac{\pi}{180}\) radian

So given the number is 72/8

72/8 = 9

1 = \(\frac{\pi}{180}\) radian

9 \(=\frac{\pi}{180}\times9=\frac{\pi}{20}\) radian

Hence the radian value of 72/8 is \(\frac{\pi}{20}\) radian.

Answer: I just did this it’s “yes, because AB=BC” I believe sorry if it’s wrong

Step-by-step explanation: you can go on a app and put the points so it can graph 4 u

An isosceles triangle is a triangle whose two sides are of equal length. Triangle ABC is an isosceles triangle because of AB= BC.

An isosceles triangle is a triangle whose two sides are of equal length while the third side is of different length.

For the triangle to be an isosceles triangle, we need to find the length of each side of the triangle. Therefore, the length will be,

\(AB = \sqrt{(-1-7)^2+(-8-(-2))^2} = \sqrt{(-8)^2+(-6)^2} = 10\)

\(BC = \sqrt{(5-(-1))^2+(0-(-8))^2} = \sqrt{(6)^2+(8)^2} = 10\)

\(AC = \sqrt{(5-7)^2+(0-(-2))^2} = \sqrt{(-2)^2+(2)^2} = 2\sqrt2\)

Since for a triangle to be an isosceles triangle, it is needed that the two sides of the triangle must be equal while the third side should have different lengths, and as in the given triangle the length of AB=BC. It is an isosceles triangle.

Hence, triangle ABC is an isosceles triangle because of AB= BC.

Answer:

y=-2/3-2

Step-by-step explanation:

Answer:

\(y\leq \frac{1}{2} x+3\)

Step-by-step explanation:

slope intercept form is \(y=mx+b\) where \(m\) is the gradient and \(b\) is the y-intercept (the number at which it crosses the y axis)

firstly find the equation for this line:

the gradient can be found with the formula \(\frac{y_{2} -y_{1} }{x_{2} -x_{1} }\)

so the gradient is \(\frac{4-3}{2-0}=\frac{1}{2} =0.5\)

the y intercept is where it crosses the y axis so it is simply 3

our equation for the line is now \(y=\frac{1}{2} x+3\) but the question is asking for an equality where the shaded area is BELOW the line.

so the inequality is \(y\leq \frac{1}{2} x+3\)

Answer:

y ≤ \(\frac{1}{2}\) x + 3

Step-by-step explanation:

the equation of the line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 3) ← 2 points on the line

m = \(\frac{3-0}{0-(-6)}\) = \(\frac{3}{0+6}\) = \(\frac{3}{6}\) = \(\frac{1}{2}\)

the line crosses the y- axis at (0, 3 ) ⇒ c = 3

y = \(\frac{1}{2}\) x + 3 ← is the equation of the line

the solution lies below the line and on the line.

as line is solid use ≤

y ≤ \(\frac{1}{2}\) x + 3

y=(x+3)^2-1

The correct shape which have created this three-dimensional object is shown in Option A.

Now, We know that;

When a body is rotating, there is a line that all the parts are turning about.  

The parts farther away from that line travel on larger circle around that line, so they are moving faster.  

Parts closer to the line follow smaller circles and move more slowly as a result.  

Points right on the line do not travel at all.  

Hence, On the diagram you can see the greatest circle, formed by rotation.

The points that form this circle are at the greatest distance from the axis of rotation.

So you can see that only first or second options are true.

But the second one is false, because the figure is not symmetric and therefore, formed shape must not be symmetric too.

Hence: correct option is A.

hello

to solve this question, we need to write down details we have first in order to take some key facts into consideration.

1 bus (70 students + 6 chaperones) = $1300

1 van (10 students +1 chaperone) = $80

we have to take into consideration that the trip can only accomodate only 60 chaperone and also find the least expensive options to take.

the total number of students in senior class = 630 students

the best option would be to pick 7 buses and 15 vans

7 buses would be

7 buses would accomodate 490 students and will require

7 buses will accomodate 490 students and would require 42 chaperones.

now we would need at least 14 vans to accomodate the remaining students.

Answer:

Step-by-step explanation:

Mathematical

y = x - 3

y = 2x + 8

----

x - 3 = 2x + 8

-x = 11

x = -11

If x = -11:

y = -11 -3

y = - 14

y = 2

(-11,-14)

The grapical solution is attached, and it confirms (-11,-14).

Answer: f(x) = -1/2(x+3)

Example: g(x) = -1/2(-x-3)

This function is a dilation and a reflection of the parent function f(x) because when graphed, the two functions have the same shape but are reflected over the y-axis and are half the size of the original.

At a significance level of 0.01, we can confidently state that the student's claim is true.

The hypothesis in this question can be stated as follows:

Null Hypothesis: H0: μ1 = μ2 (There is no difference between the mean of four-year college enrollment and two-year college enrollment.)

Alternative Hypothesis: H1: μ1 > μ2 (Mean enrollment of four-year colleges is greater than the mean enrollment of two-year colleges in the United States.)

The significance level (α) is given as 0.01, which represents the probability of rejecting the null hypothesis when it is actually true.

To calculate the test statistic, we can use the formula:

z = ((X1 - X2) - (μ1 - μ2)) / √((σ1² / n1) + (σ2²  / n2))

Substituting the given values:

z = ((6193 - 4305) - (0)) / √((598²  / 35) + (572²  / 35))

z = 10.33

Since this is a right-tailed test, we need to compare the test statistic with the critical value. At a significance level of 0.01, the critical value is 2.33.

The calculated test statistic (10.33) is greater than the critical value (2.33). Therefore, we reject the null hypothesis and conclude that there is enough evidence to support the claim that the mean enrollment at four-year colleges is higher than at two-year colleges in the United States.

In conclusion, at a significance level of 0.01, we can confidently state that the student's claim is true. The mean enrollment at four-year colleges is higher than at two-year colleges in the United States.
