Answer:

0.89417

Step-by-step explanation:

Using the relation to obtain the Zscore :

Z = (x - mean) ÷ standard deviation / sqrt(n)

x = 0.8535

Mean = 0.8565

Standard deviation = 0.0518

Sample size, n = 465

P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)

P(x ≥ 0.8535) = - 0.003 / 0.0024021

P(x ≥ 0.8535) = - 1.249

P(Z ≥ - 1.249) = 0.89417

if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.

No, it is not possible to make two triangles that are not congruent and have three pairs of congruent angles. This is because if two angles of a triangle are congruent, then the third angle must also be congruent by the Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees. If two triangles have three pairs of congruent angles, then all three angles in each triangle are congruent, meaning they have the same measure. However, this does not guarantee that the sides of the triangles are congruent. In order for two triangles to be congruent, they must have the same angle measures as well as the same side lengths. Therefore, if two triangles have three pairs of congruent angles, then they must be congruent to each other by the Angle-Angle-Angle (AAA) congruence theorem, and thus cannot be non-congruent.

Step-by-step explanation:

we use the point-slope approach :

y - y1 = m(x - x1)

m is the slope, and (x1, y1) is a point on the line.

so,

1.

y - 2 = 7(x - 1) = 7x - 7

y = 7x - 5

2.

y - -1 = -1×(x - 3) = -x + 3

y + 1 = -x + 3

y = -x + 2

3.

y - 5 = -4(x - -2) = -4x - 8 (3x a "-" is a "-" for 8)

y = -4x - 3

4.

y - 5 = 5/3 × (x - 3) = 5x/3 - 5

y = 5x/3 or 5/3 × x

Answer:

1. \(7x-y=5\)

2. \(x+y=2\)

3. \(4x+y=-3\)

4. \(5x-3y=0\)

Step-by-step explanation:

Since we already know the slope and the coordinates of one point, first use the point-slope form to create an equation.

\(y-k=m(x-h)\)

\(y-2=7(x-1)\)

\(y-2=7x-7\)

\(7x-y=5\)

\(y+1=-1(x-3)\)

\(y+1=-x+3\)

\(x+y=2\)

\(y-5=-4(x+2)\)

\(y-5=-4x-8\)

\(4x+y=-3\)

\(y-5=\frac{5}{3} (x-3)\)

\(y-5=\frac{5}{3}x-5\)

\(3y-15=5x-15\)

\(5x-3y=0\)

The measure of segments mAG, mAC, and mBC are 11.4, 16.1 and 7.1 respectively,

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
Apply Pythagoras theorem in triangle ABG,

mAG = √[7² + 9²]
mAG = √[49 + 81]
mAG = √[130] = 11.4
Apply Pythagoras theorem in triangle BGC,
mBC = √[10² - 7²]
mBC = √51
mBC = 7.1

Now

mAC = mAB  + mBC
mAC = 9 + 7.1
mAC = 16.1

Thus, the segments mAG, mAC, and mBC have measures of 11.4, 11.1, and 7.1, respectively.

Answer:

3:2

Step-by-step explanation:

The ratio of CM to ME is the ratio of lengths of the two segments.  Segment length is the square root of the sum of the squares of the differences of each coordinate direction.  For CM the difference of the x direction is

( -3-(+6) or -6 and the y direction (-7-(-4)) or 3.  Squaring each: -6^2 = 36 and 3^2 = 9.  The sum is 45 and the square root of 45 is 3 (5) ^1/2 by removal of the perfect squares.  For ME the x direction is 3 - (+7) = -4 and for the y direction is -4 - (-2) = 2.  Squaring each is -4^2 = 16 and 2^2 = 4. The sum is 20. The square rot of 20 is 2 (5) ^1/2.  The ratio is 3 (5)^ 1/2 : 2 (5) ^1/2 .  Since the square root of five is in both parts it can be removed.  Thus the ratio becomes 3 : 2.

By using  Fundamental Theorem of Calculus, we find the derivative of the function g(x) = In { sqrt( t + t^3)dt } limit from x to 0 is  ln(sqrt(x + x^3)).  The derivative of the function g(x) = { In (1+t^2) dt} where limit are from x to 1 is  ln(1 + x^2).

The Fundamental Theorem of Calculus, which states that if a function is defined as the definite integral of another function, then its derivative is equal to the integrand evaluated at the upper limit of integration.

So, applying this theorem, we have:

g'(x) = d/dx [∫x_0 ln(sqrt(t + t^3)) dt]

= ln(sqrt(x + x^3)) * d/dx (x) - ln(sqrt(0 + 0^3)) * d/dx (0)

= ln(sqrt(x + x^3))

Therefore, g'(x) = ln(sqrt(x + x^3)).

Using the Fundamental Theorem of Calculus, we have:

g'(x) = d/dx [∫1_x ln(1 + t^2) dt]

= ln(1 + x^2) * d/dx (x) - ln(1 + 1^2) * d/dx (1)

= ln(1 + x^2)

Therefore, g'(x) = ln(1 + x^2).

By solving an Inequality is almost the same as solving an equation.

We simply move x-term to the same term and the number or rather a constant to the same side.

\(4x - 5x > - 2 - 5 \\ - x > - 7\)

A quick reminder. If the coefficient for the variable that we want to solve is in negative. For Inequality, moving the negative coefficient for the variable to another side will force the Inequality sign to swap to opposite.

The area of the pentagon with vertices (0, 0), (3, 1), (1, 2), (0, 1), and (-2, 1) is 6 square units.

To find the area of a pentagon given its vertices, we can divide it into triangles and then calculate the area of each triangle separately.

Let's label the given vertices as A(0, 0), B(3, 1), C(1, 2), D(0, 1), and E(-2, 1). We can divide the pentagon into three triangles: ABD, BCD, and CDE.

To calculate the area of a triangle, we can use the shoelace formula. Let's apply it to each triangle:

Triangle ABD: Coordinates: A(0, 0), B(3, 1), D(0, 1)

Area(ABD) = |(0 * 1 + 3 * 1 + 0 * 0) - (0 * 3 + 1 * 0 + 1 * 0)| / 2

= |(0 + 3 + 0) - (0 + 0 + 0)| / 2

= |3 - 0| / 2

= 3 / 2

= 1.5 square units

Triangle BCD: Coordinates: B(3, 1), C(1, 2), D(0, 1)

Area(BCD) = |(3 * 2 + 1 * 0 + 0 * 1) - (1 * 1 + 2 * 0 + 3 * 0)| / 2

= |(6 + 0 + 0) - (1 + 0 + 0)| / 2

= |6 - 1| / 2

= 5 / 2

= 2.5 square units

Triangle CDE: Coordinates: C(1, 2), D(0, 1), E(-2, 1)

Area(CDE) = |(1 * 1 + 2 * 1 + (-2) * 0) - (2 * 0 + 1 * (-2) + 1 * 1)| / 2

= |(1 + 2 + 0) - (0 - 2 + 1)| / 2

= |3 - (-1)| / 2

= 4 / 2

= 2 square units

Now, we can sum up the areas of the three triangles to find the total area of the pentagon:

Total area = Area(ABD) + Area(BCD) + Area(CDE)

= 1.5 + 2.5 + 2

= 6 square units

Therefore, the area of the pentagon with vertices (0, 0), (3, 1), (1, 2), (0, 1), and (-2, 1) is 6 square units.

In conclusion the correct solution is 1.54 as the spending multiplier.

The spending multiplier is a measure of the impact of changes in spending on overall economic output. It represents the amount by which a change in spending is multiplied throughout the economy. In this case, the question provides a marginal propensity to consume (MPC) of 0.65.

The MPC represents the portion of additional income that individuals choose to spend rather than save. Since the MPC is 0.65, it means that for every additional dollar earned, individuals will spend 65 cents and save the remaining 35 cents.

To calculate the spending multiplier, we take the reciprocal of the MPC. In this case, the reciprocal of 0.65 is approximately 1.54. This means that a change in spending of $1 will result in a total change in economic output of approximately $1.54.

For example, if there is an increase in government spending by $100 million, the total impact on the economy will be approximately $154 million. This is because the initial increase in spending will lead to additional income for individuals, who in turn will spend a portion of that income, leading to further rounds of spending and economic activity.

Therefore, the correct answer is 1.54 as the spending multiplier.

The area of the rectangle ABCD is approximately 29.15 square units.

To find the area of the rectangle ABCD, we can use the formula for the area of a rectangle, which is given by the product of its length and width.

Let's first find the length and width of the rectangle using the coordinates of its vertices.

Length AB = distance between points A and B

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(1 - (-4))² + (4 - 4)²]

= √[5² + 0²]

= √25

= 5

Width BC = distance between points B and C

= √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(-4 - 1)² + (1 - 4)²]

= √[(-5)² + (-3)²]

= √[25 + 9]

= √34

Now that we have the length and width, we can calculate the area of the rectangle.

Area = Length × Width

= 5 × √34

≈ 5 × 5.83

≈ 29.15 square units

Therefore, the area of the rectangle ABCD is approximately 29.15 square units.

The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic if the expected frequency in each cell is at least 5. This rule of thumb ensures that the test statistic is more likely to follow a chi-square distribution.

The chi-square distribution provides a good approximation to the sampling distribution of the chi-square statistic if the expected frequency in each cell is at least 5. This is known as the "rule of thumb" for the chi-square test of independence. It ensures that the distribution is not too skewed or too flat, and that the test statistic is more likely to follow a chi-square distribution. When the expected frequency in any cell is less than 5, the chi-square test may not be appropriate, and alternative tests such as Fisher's exact test should be used instead.
