The height of the average fourth grader is 137cm 1mm. This height can be determined by multiplying 3 by the average height of a newborn baby.

Given information,

The average height of babies = 45 cm 7mm

45 cm 7 mm is equivalent to 45.7 cm (since there are 10 millimeters in a centimeter).

Let the height of a fourth grader be x.

According to the question,

The height of a fourth grader (x) = 3 × the average height of a newborn baby

The height of a fourth grader (x) = 3 × 45.7

The height of a fourth grader (x)= 137.1 = 137cm 1mm

Therefore, the height of a fourth grader is 137cm 1mm.

Angle C of the triangle measures 40°.

Side AC = 18.84

Side AB= 25.79

Given triangle,

∠A = 112°

∠B = 28°

BC = 37

Now,

Sum of all the interior angles of triangle is 180.

So,

∠A + ∠B +∠C = 180°

112° + 28° + ∠C = 180°

∠C = 40°

Now,

According to sine rule,

Ratio of side length to the sine of the opposite angle is equal.

Thus,

a/SinA = b/SinB = c/SinC

Let,

BC = a

AC = b

AB = c

So,

a/Sin112 = b/Sin28 = c/Sin40

37/0.921 = b/0.469 = C/0.642

Solving,

AB = c = 25.79

AC = b = 18.84

The dollar value of total revenue at each price is $[tex]0[/tex], $[tex]10[/tex], $[tex]12[/tex], $[tex]12[/tex], $[tex]10[/tex], and $[tex]6[/tex]. Total revenue will be the greatest at a price of $[tex]4[/tex], with [tex]3[/tex] units sold.

To find the dollar value of total revenue at each price, we can multiply the price by the corresponding quantity in the demand schedule:

Price: $[tex]6[/tex]

Quantity: [tex]0[/tex]

Total Revenue: $[tex]6 \times 0[/tex] = $[tex]0[/tex]

Price: $[tex]5[/tex]

Quantity: [tex]2[/tex]

Total Revenue: $[tex]5 \times 2[/tex] = $[tex]10[/tex]

Total Revenue: $[tex]2 \times 5[/tex] = $[tex]10[/tex]

Price: $[tex]1[/tex]

Quantity: [tex]6[/tex]

Total Revenue: $[tex]1 \times 6[/tex] = $[tex]6[/tex]

To determine at which price the total revenue will be the greatest, we observe that the highest total revenue occurs at the price with the highest quantity sold. In this case, the price with the highest quantity is $[tex]3[/tex], and the corresponding quantity sold is [tex]4[/tex] units.

The probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75, or 75%.

To find the probability that a customer ordered vanilla ice cream given they ordered a sundae, we can use the concept of conditional probability.

The conditional probability of an event A given event B is denoted as P(A|B) and is calculated as the probability of both events A and B occurring divided by the probability of event B.

In this case, we want to find P(vanilla|sundae), which represents the probability of a customer ordering vanilla ice cream given that they ordered a sundae.

Using the given probabilities:

P(vanilla) = 0.3

P(sundae) = 0.2

P(vanilla and sundae) = 0.15

The probability of a customer ordering a sundae is the denominator for the conditional probability. Therefore, P(sundae) will be the denominator.

P(vanilla|sundae) = P(vanilla and sundae) / P(sundae)

Substituting the given values:

P(vanilla|sundae) = 0.15 / 0.2

Now we can simplify:

P(vanilla|sundae) = 0.15 / 0.2

= 0.75

Therefore, the probability that a customer ordered vanilla ice cream given they ordered a sundae is 0.75, or 75%.

In conclusion, based on the given probabilities, there is a 75% chance that a customer who ordered a sundae also ordered vanilla ice cream.

Step-by-step explanation:

The probability that a given student said math was their favorite subject was 3.44

The mathematical notion of probability measures the possibility of an event happening. A number between 0 and 1 is used to indicate it, with 0 denoting impossibility (the event won't happen) and 1 denoting certainty (the event will unquestionably happen). In probability theory, the probability of an event is determined based on a set of assumptions or information available. It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Here, the total outcome is 299 and favorable outcome is 87.

Hence, the probability is 299/87 = 3.44

Therefore, probability that a given student said math was their favorite subject was 3.44.

The sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.

Using the formula:

D = 10 * log(I/I0),

where D represents the sound intensity in decibels, I is the given sound intensity, and I0 is the reference intensity of 10^-12 watts per square meter.

Substituting the given values:

D = 10 * log(8.2*10^2 / 10^-12).

To simplify the calculation, we can rewrite the division as multiplication by the reciprocal:

D = 10 * log(8.2*10^2 * 10^12).

Using the logarithm property log(a * b) = log(a) + log(b):

D = 10 * (log(8.2) + log(10^2) + log(10^12)).

Using the logarithm property log(a^b) = b * log(a):

D = 10 * (log(8.2) + 2 * log(10) + 12 * log(10)).

Since log(10) = 1:

D = 10 * (log(8.2) + 2 + 12).

D = 10 * (log(8.2) + 14).

Using a calculator or logarithm table, we can find log(8.2) ≈ 0.913.

D = 10 * (0.913 + 14).

D = 10 * 14.913.

D ≈ 149.13.

Therefore, the sound emitted from the jet plane has a sound intensity of approximately 149.13 decibels.

Answer: Area = = 38.5 - Perimeter - 29.6819.

Step-by-step explanation:

To find the perimeter and area of a triangle with vertices L(5,5), M(-2,-4), and N(5,-6), we can use the distance formula and the formula for the area of a triangle.

Perimeter:

The perimeter of a triangle is the sum of the lengths of its sides. We can find the lengths of each side using the distance formula, which states that the distance between two points (x1, y1) and (x2, y2) is given by:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Using this formula, we can calculate the lengths of LM, MN, and NL:

LM = √((-2 - 5)^2 + (-4 - 5)^2)

= √((-7)^2 + (-9)^2)

= √(49 + 81)

= √130

MN = √((5 - (-2))^2 + (-6 - (-4))^2)

= √((7)^2 + (-2)^2)

= √(49 + 4)

= √53

NL = √((5 - 5)^2 + (-6 - 5)^2)

= √((0)^2 + (-11)^2)

= √(0 + 121)

= √121

= 11

The perimeter of the triangle is the sum of these three sides:

Perimeter = LM + MN + NL

= √130 + √53 + 11 = 29.6819

Area:

To calculate the area of the triangle, we can use the formula for the area of a triangle using the coordinates of its vertices. The formula is given by:

Area = 0.5 * |x1(y2 - y3) + x2(y3 - y1) + x3(y1 - y2)|

Using the coordinates of L(5,5), M(-2,-4), and N(5,-6), we can calculate the area:

Area = 0.5 * |5(-4 - (-6)) + (-2)(-6 - 5) + 5(5 - (-4))|

= 0.5 * |5(2) + (-2)(-11) + 5(9)|

= 0.5 * |10 + 22 + 45|

= 0.5 * |77|

= 38.5

Therefore, the perimeter of the triangle is given by √130 + √53 + 11 = 29.6819 units, and the area of the triangle is 38.5 square units.

The value of x indicated in the right angle of EFG is determined as 36.

option D.

The value of x is calculated by applying the principle of sum of angles in a right angle triangle as follows;

A right triangle has a right angle and two angles that are complementary.

If angle EFG is a right angle, then the sum of angles at point F is 90 degrees.

The value of x is calculated by setting up the following equations;

2x + 6 + 12 = 90
