2*2=4

if both measures are doubled, then the result will be doubled too.

The value of x, obtained using the property of bisected angles is 10

Bisected angles are angles that are split by a line segment in two to create two angles of the same measure.

The specified information indicates;

[tex]\overrightarrow{GI}[/tex] bisects ∠DGH

m∠DGI = x - 3

m∠IGH = 2·x - 13

The angle addition postulate indicates that we get;

m∠DGH = m∠DGI + m∠IGH

The definition of the bisected angle ∠DGH indicates that we get;

∠DGI = ∠IGH

Therefore;

x - 3 = 2·x - 13

2·x - 13 = x - 3

The measure of angle a is 30° , angle b is 60° and angle c is 105°  calculated from the properties of angles and of triangle.

When two straight lines intersect each other at some angle, say line AB intersect line CD, then the opposite angles formed by the two lines are called vertically opposite angles. A pair of vertically opposite angles are equal to each other.

Angle a is formed at the intersection of the two straight lines, say AB and CD. The angle opposite to angle is 30°.

Thus from the definition of vertically opposite angles we get,

Angle a = 30° , since pair of vertically opposite angles are equal to each other.

In a right angle triangle one of three angles is 90° and the other two angles are acute angles. The sum of all the angles of a triangle is 180°.

Say  ΔMNO is a right angle triangle where angle a is one of the other two acute angles (where angle a = 30°).

The third angle (acute) is b.

Thus from the sum of triangle we get,

Angle a + Angle b + 90° = 180°

⇒ 30° + Angle b + 90° = 180°

⇒ Angle b = 60°

Here angle c is an angle labelled in a triangle (on the left of the previous triangle, say ΔMNO).

Two angles are said to be adjacent angles when they have a common vertex and side. The pair of adjacent angles sum to 180° , that is they are supplementary angles.

The adjacent angle of Angle c is 75°.

Thus, Angle c + 75° = 180°

⇒ Angle c = 105°

Answer:

To write the equation of the line that represents Calvin’s spending on candy, we need to first find the slope and the y-intercept of the line.

We can use the two points given in the problem: (4, 28) and (10, 25)

Slope (m) = (y2 - y1) / (x2 - x1)

= (25 - 28) / (10 - 4)

= -3/6

= -1/2

The slope represents the rate at which Calvin is spending money on candy.

Now, we can use the point-slope form of the equation of a line to find the equation of the line.

y - y1 = m(x - x1)

y - 28 = (-1/2)(x - 4)

y - 28 = (-1/2)x + 2

y = (-1/2)x + 30

Therefore, the equation of the line that represents Calvin’s spending on candy is y = (-1/2)x + 30.

Answer: Equation that represents his spending on candy- y = (³⁄₁₀) x

X = number of candy

Step-by-step explanation:

y = money spend            x = number of candy

y = (m)x

cost for 10 pieces of candy = $(28 - 25) = $3

⇛ 3 = (m)x10 (x = 10 & y = 3)

⇛m=(³⁄₁₀)

Therefore the equation representing his spending on candy is

⇛ y = (³⁄₁₀) x

The margin of error is an important factor in determining the sample size needed to estimate a parameter, it is not the only factor - False.

Other factors that need to be considered include the level of confidence desired, the variability of the population being sampled, and the size of the population.

The margin of error is the amount of error that is acceptable in the estimate of the parameter. The smaller the margin of error desired, the larger the sample size needed.

A higher level of confidence requires a larger sample size, as there is less room for error in the estimate. The variability of the population being sampled also plays a role in determining the sample size needed.

Finally, the size of the population being sampled also affects the sample size needed.

A smaller population requires a smaller sample size, while a larger population requires a larger sample size to ensure a representative sample.

In summary, while the margin of error is an important factor in determining the sample size needed to estimate a parameter, it is not the only factor.

The measure of side ‘b’ in the given triangle ABC, with angle A measuring 54 degrees and angle C measuring 59 degrees and side BC measuring 11 is option-c:12.516, which is found using Sine-law.

In a scalene or oblique triangle (a non-right triangle), the law of sine describes the relationship between the sides and angles. Trigonometric laws such as the law of sines and law of cosines are crucial when "solving a triangle" by calculating the unknown angles or sides. The ratio of a triangle's side lengths to the sine of each of its opposite angles must be equal in order for the sine rule to apply. Triangle side length ratios to their corresponding opposite angles are connected by the law of sines. All three sides and the diagonal angles maintain the same ratio.

Given that ∠A= 54° ,∠C= 59° & side BC=a=11

We know that ∠A + ∠B + ∠C = 180°   {angle sum property}

Consider △ABC,

54° + 59° +  ∠B = 180°

113° +  ∠B = 180°

∠B = 180°- 113°

∠B = 67°

Applying Sine-Law,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B} = \frac{C}{sin\ C}[/tex]

By using,

[tex]\frac{A}{sin\ A} =\frac{B}{sin\ B}[/tex] , we get:

The value of k is approximately 0.034. The projected Hispanic resident population in 2015 is approximately 73.9 million. The Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.

To find k, we can use the fact that A = 35.3 million when t = 0 (i.e., in 2000), and A = 50.5 million when t = 10 (i.e., in 2010). Substituting these values into the exponential growth function, we get

35.3 = 35.3e^0k

50.5 = 35.3e^(10k)

Dividing the second equation by the first equation, we get

50.5/35.3 = e^(10k)

Taking the natural logarithm of both sides, we get

ln(50.5/35.3) = 10k

Solving for k, we get

k ≈ 0.034

Therefore, the exponential growth function is A = 35.3e^(0.034t).

To project the Hispanic resident population in 2015, we need to find A when t = 15 (i.e., 15 years after 2000). Substituting t = 15 into the exponential growth function, we get

A = 35.3e^(0.034*15) ≈ 73.9 million

Therefore, the projected Hispanic resident population in 2015 is approximately 73.9 million.

To find the year in which the Hispanic resident population reaches 70 million, we need to solve the exponential growth function for t when A = 70. Substituting A = 70 into the exponential growth function, we get

70 = 35.3e^(0.034t)

Dividing both sides by 35.3, we get

e^(0.034t) = 70/35.3

Taking the natural logarithm of both sides, we get

0.034t = ln(70/35.3)

Solving for t, we get

t ≈ 24.7

Therefore, the Hispanic resident population will reach 70 million in approximately 24.7 years after 2000, which corresponds to the year 2024.
