A child. Should no longer use a boister seat when they reach 4'9" tall Janet is 59 inches tall. Can she go without a booster seat

Answer:

B.

Step-by-step explanation:

you know that (a+b+c)/d is the same as a/d + b/d + c/d.

and (a×b)/(c×d) is the same as (a/c)×(b/d).

and the powers of variables subtract when the variables are divided, and the powers add when the variables are multiplied.

14a⁸y³ / 7a⁴y

14/7 = 2

a⁸/a⁴ = a⁴

y³/y = y²

=> 2a⁴y² is the first part. that eliminates already all other answer options. only B can be right.

but let's practice and look at the second part :

-7a⁴y⁵ / 7a⁴y

-7/7 = -1

a⁴/a⁴ = 1

y⁵/y = y⁴

=> -y⁴ is the second part. B is still confirmed.

the third part :

28a¹²y² / 7a⁴y

28/7 = 4

a¹²/a⁴ = a⁸

y²/y = y

=> + 4a⁸y is the third part. B confirmed.

Answer:

answer is false

Answer:

(a) The unit rate for car B is greater because the slope is greater than the slope for car A.

Step-by-step explanation:

We have been given a graph that represents the distance cars A and B travel. We are asked to choose the correct option about our given graphs.

Since slope represents the change in y-value with respect to change in per unit x value, so slope is also unit rate of the graph.

Let us find the slope of car A using points (8,5) and (0,0).

Let us find the slope of car B using points (5,8) and (0,0).

We can see that slope of car B is greater than slope of car A, therefore, option A is the correct choice.

55 adult tickets were sold that day.

Let us assume the number of adult tickets sold is x.

Given that the child admission is $5.50 and adult admission is $9.80.

We will set up the following equations:

Simplifying the equations:

x + 131 - x = 131

9.80x + 720.50 - 5.50x = 957.00

Combining like terms:

131 = 131

4.30x = 236.50

Dividing both sides by 4.30:

x = 55.

The Diameter of the circular area that gets watered by the sprinkler is 20 yards.

The equation provided is in the standard form for the equation of a circle:

(x - h)² + (y - k)² = r²

Where (h, k) represents the coordinates of the center of the circle, and r represents the radius.

Comparing the given equation (x - 11)² + (y - 3)² = 100 with the standard form, we can deduce that the center of the circle is at the point (11, 3), and the radius squared is 100.

To find the radius, we take the square root of the radius squared:

radius = √100 = 10 yards

The diameter of a circle is equal to twice the radius. Therefore, the diameter of the circular area that gets watered by the sprinkler is:

diameter = 2 * radius = 2 * 10 yards = 20 yards

Hence, the diameter of the circular area that gets watered by the sprinkler is 20 yards.

Step-by-step explanation:

Area of the region inside the circle r=4cos(theta) and outside the circle r=2 is 4π/3 + 2√3

A form created using the polar coordinate system is called a polar curve. Points on polar curves have varying distances from the origin (the pole), depending on the angle taken off the positive x-axis to calculate distance. Both well-known Cartesian shapes like ellipses and some less well-known shapes like cardioids and lemniscates can be described by polar curves.

r = 1 − cosθsin3θ

Polar curves are more useful for describing paths that are an absolute distance from a certain point than Cartesian curves, which are good for describing paths in terms of horizontal and vertical lengths. Polar curves can be used to explain directional microphone pickup patterns, which is a useful application. Depending on where the sound is coming from outside the microphone, a directional microphone will take up sounds with varied tonal characteristics. A cardioid microphone, for instance, has a pickup pattern like a cardioid.

The area between two polar curves can be found by subtracting the area inside the inner curve away from the area inside the outer curve.

The figure attached shows the bounded region of the two graphs. The red curve is  r=4cos⁡(θ) and the blue curve is r=2.

The points of intersection of the two curves are

θ = π/3 and 5π/3

The area is calculated as follows:

Since the bounded region is symmetric about the horizontal axis, we will find the area of the top region, and then multiply by 2, so as to get the total area.

A = 2 \(\(\int_{0}^{\pi /3}\) ½ (4 cos (θ)² − ½ (2)² dθ

  =  \(\(\int_{0}^{\pi /3}\) 16 cos2 (θ) − 4dθ

  = \(\(\int_{0}^{\pi /3}\) 8 (1+cos(2θ)) − 4dθ

  =\(\(\int_{0}^{\pi /3}\) 4 + 8 cos (2θ) dθ

  = [4θ + 4sin (2θ)] \(\(\int_{0}^{\pi /3}\)

  = 4π/3 + 2√3

Considering the properties of the normal curve, if we know the mean and standard deviation, we are then able to calculate the area under the curve between any score and the mean

Standard Deviation Normal distribution:

The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. The standard normal distribution is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation. For the standard normal distribution, 68% of the observations lie within 1 standard deviation of the mean; 95% lie within two standard deviation of the mean; and 99.9% lie within 3 standard deviations of the mean. However, when using a standard normal distribution, we will use "Z" to refer to a variable in the context of a standard normal distribution. Since the area under the standard curve = 1, we can begin to more precisely define the probabilities of specific observation.

(4) The series diverges by the Comparison Test. Each term is greater than that of a divergent geometric series.

To determine whether the series converges or diverges, we can use the Comparison Test.
First, we can simplify the series by dividing both the numerator and denominator by n:
[Infinity] (4 + 1/n) / (3 - 5/n)

As n approaches infinity, both the numerator and denominator approach 4/3, so we can write:
[Infinity] (4 + 1/n) / (3 - 5/n) = [Infinity] 4/3

Since the harmonic series [Infinity] 1/n diverges, we can conclude that the original series diverges as well.
Therefore, the correct answer is:

When designing a questionnaire, overcoming measurement errors can be reduced by various strategies. However, one of the options listed does not contribute to reducing measurement errors. The option that does not help in reducing measurement errors is: c. The use of many answer scale categories.

Measurement errors in questionnaires can arise due to various factors, such as respondent bias, response inconsistency, and ambiguous or confusing question wording. To minimize these errors, researchers employ different techniques. Let's examine the options:

a. The use of a linear rating scale with only the extreme categories labeled: This technique helps by simplifying the rating scale and providing clear reference points, which can enhance response accuracy.

b. Positioning difficult and important questions at the beginning and end of the questionnaire: This strategy is known as primacy and recency effects. Placing challenging and significant questions at the start and end can improve response quality as respondents are more focused and attentive during those sections.

c. The use of many answer scale categories: This option, contrary to the others, does not help in reducing measurement errors. Having numerous answer scale categories can increase respondent confusion, lead to midpoint bias, and result in inconsistent or inaccurate responses.

d. Positioning easy and straightforward questions in the questionnaire: This technique aims to create a smooth flow and encourage respondents to answer confidently. By placing easier questions strategically, respondents may feel more comfortable and provide accurate responses.

The values for g and f for the length of sides of the trapezium are 8 and 6 respectively.

Given the area of trapezium = 60 cm², then:

1/2 × (g + 4g) × f = 60 cm²

by simplification

f(g + 2) = 60 cm²...(1)

for the area of ABCD = 48 cm², then:

f × g = 48 cm²

f = 48/g...(2)

put 48/g for f in equation (1) to get g;

48/g(g + 2) = 60

60g = 48g + 96 {cross multiplication}

60g - 48g = 96 {collect like terms}

12g = 96

g = 96/11 {divide through by 11}

g = 8

The price of the item after the first month can be expressed as 300 - (0.20 * 300) or 300 * (1 - 0.20). The price of the item after the second month can be expressed as (300 - (0.20 * 300)) - (0.25 * (300 - (0.20 * 300))) or 300 * (1 - 0.20) * (1 - 0.25).

Expression 1: Price after the first month = 300 - (20% of 300)

We subtract 20% of the original price, which is equivalent to multiplying 300 by 0.20 and subtracting it from 300. This represents a 20% decrease in price.

Expression 2: Price after the first month = 300 * (1 - 20%)

We calculate the new price by multiplying the original price by 1 minus 20% (which is 0.20). This represents a 20% decrease in price.

Math drawing:

Let's consider a bar graph where the length of the bar represents the original price (300). We can visualize a 20% decrease by shading out 20% of the length of the bar.

[300] ------X------- (X represents the 20% decrease portion)

Expression 1: Price after the second month = (300 - 20%) - (25% of (300 - 20%))

We first calculate the price after the first month using one of the expressions from question 1. Then, we subtract 25% of that new price. This represents a 25% decrease in the already decreased price.

Expression 2: Price after the second month = 300 * (1 - 20%) * (1 - 25%)

We calculate the new price by multiplying the original price by (1 - 20%) to represent the first month's decrease, and then further multiply it by (1 - 25%) to represent the second month's decrease.

The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:

"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."

The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.

Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.

In conclusion, the converse statement does not hold for all figures. It is important to note that the converse of a true statement is not always true, and separate analysis is required to determine the validity of the converse in specific cases.
