Answer:

shaded area ≈ 69.53 cm²

Step-by-step explanation:

the shaded area (A) is calculated as

A = area of square - area of circle

area of square = 18² = 324

area of circle = πr² ( r is the radius )

the diameter of the circle = 18 , so r = 18 ÷ 2 = 9

area of circle = π × 9² = 81π

then

A = 324 - 81π ≈ 69.53 cm² ( to 2 decimal places )

Based on the supply graph and demand graph shown above, the price at the point of equilibrium is $ 30.

Demand refers to quantity of a commodity that the consumers are willing to, able to purchase at a given price during a given period of time. Supply refers to quantity of a commodity that the producers are willing to, able to offer for sale at a given price during a given period of time.

Demand curve slopes downward due to inverse relationship between price and quantity demanded whereas supply curve slopes upward due to direct relationship between quantity supplied and price. When both demand and supply curve intersect with each other balance is achieved. Intersection point between demand and supply curve is known as equilibrium.

At this point when prices are equal is known as equilibrium price and when quantiy demanded or supplied are equal it is known as equilibrium quantity. When we combine the given graph. Equilibrium is achieved at a point when price is equal to $ 30 and quantity is equal to 20 units.

The statement, yes, they are independent because P(student) = 0.8 and P(student | logo A) = 0.8.

To determine if being a student and preferring logo A are independent events, we need to compare the probabilities of these events occurring.

The probability of being a student, denoted as P(student), is given as 0.8. This means that out of the total population (125), 80% are students.

The probability of a student preferring logo A, denoted as P(student | logo A), is given as 0.8.

This means that out of the students (100), 80% prefer logo A.

If the events of being a student and preferring logo A are independent, then the probability of a student preferring logo A (P(student | logo A)) should be the same as the probability of being a student (P(student)).

However, in the given options, both options A and D state that P(student | logo A) = 0.8, which is the same as P(student).

Answer:

  see below

Step-by-step explanation:

You want the piecewise function that gives straight line segments between domain boundary points (-8, 5), (-2, -9), (1, -2), (8, 4).

The two-point equation for the slope of a line is ...

  m = (y2 -y1)/(x2 -x1)

For the first pair of points, the slope is ...

  m = (-9 -5)/(-2 -(-8)) = -14/6 = -7/3

The attached calculator image shows the computation of slope for the other two segments. Those slopes are 7/3 and 6/7.

The slope-intercept form of the equation for a line can be rearranged to give the y-intercept:

  y = mx + b

  b = y - mx

In the attached, we used the (x1, y1) point for each segment. For the first segment, the y-intercept is ...

  b = 5 -(-7/3)(-8) = -41/3

The other two y-intercepts are computed to be -13/3 and -20/7.

The piecewise function that models the given data is ...

The volume of the extra space in the box is 9.0 cubic inches.

To estimate the volume of the extra space in the box, we shall find the difference between the volume of the box and the volume of the cracker tower.

First, volume of the box:

The volume can be calculated as the product of the height, length, and width (we assume the width is the same as the side length since it is a square prism):

Box volume = height * length * width

Given:

height = 8 inches

side length = 2 inches

Box volume = 8 * 2  * 2

= 32  in³

Next, the volume of the cracker tower:

The tower of the cracker is cylindrical, so we shall use the formula for the volume of a cylinder to estimate the volume:

Tower volume = π * (radius²) * height

Given:

height = 7.9 inches

diameter = 1.9 inches

radius = diameter / 2 = 1.9  / 2 = 0.95

Tower volume = π * (0.95)² * 7.9

≈ 22.994 in³ (rounded to three decimal places)

Then, the volume of the extra space in the box:

Volume of the extra space = Tower volume - Box volume:

= 32 in³ - 22.994 in³

≈ 9.006 in³ (rounded to three decimal places)

Therefore, the volume of the extra space in the box = 9.0 in³.

The value of x in the expression is 66/114.

Let's begin by addressing the issue in detail:

Emma runs 12 km, hence the time it takes her to complete that distance is 12/x hours.

Emma cycles 26 kilometers at a speed that is 10 kilometers per hour faster than she runs.

Her cycling pace is therefore (x + 10) km/hr. Her cycle distance is 26 kilometers, which can be calculated as 26/(x + 10) hours.

Emma's total time spent cycling and running is 22 hours and 48 minutes. By dividing 48 minutes by 60, we can translate it to hours: 48/60 = 0.8 hours.

We can now formulate an equation to express the entire amount of time spent:

12/x + 26/(x + 10) = 22.8

To get rid of the denominators and solve this equation, multiply both sides by x(x + 10).

12(x + 10) + 26x = 22.8x(x + 10)

To make the calculation easier:

12x + 120 + 26x = 22.8x² + 228x

Combining comparable phrases

38x + 120 = 22.8x² + 228x

Changing the equation's order:

22.8x² + 228x - 38x - 120 = 0

22.8x² + 190x - 120 = 0

By dividing the equation by 0.4, the coefficients are made simpler:

57x² + 475x - 300 = 0

Solving the equation by x = (-b ± √(b² - 4ac)) / (2a),

x = (-475 ± √(475² - 4 * 57 * -300)) / (2 * 57)

Simplifying further:

x = (-475 ± √(225625 + 68400)) / 114

x = (-475 ± √293025) / 114

x = (-475 ± 541) / 114

Now, we can calculate the two possible solutions:

x₁ = (-475 + 541) / 114

x₁ = 66 / 114

x₁ ≈ 0.579

x₂ = (-475 - 541) / 114

x₂ = -1016 / 114

x₂ ≈ -8.912

Take x = 66/114

The 95% confidence interval for the total percentage of national park visitors who support supporting endangered species is approximately 33.3% to 52.7%.

To calculate the 95% confidence interval for the percentage of national park visitors who support supporting endangered species, we can use the formula:

Confidence Interval = Sample proportion ± (Critical value * Standard error)

Given that 43% of a sample of 100 visitors believe that additional funds should be used to preserve endangered species, the sample proportion is 0.43.

To calculate the standard error, we use the formula:

Standard Error = sqrt((p * (1 - p)) / n)

where p is the sample proportion and n is the sample size. In this case, p = 0.43 and n = 100.

Standard Error = sqrt((0.43 * (1 - 0.43)) / 100) ≈ 0.0495

The critical value for a 95% confidence interval can be obtained from a standard normal distribution table. For a 95% confidence level, the critical value is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = 0.43 ± (1.96 * 0.0495)

Confidence Interval = 0.43 ± 0.097

The lower bound of the confidence interval is 0.43 - 0.097 = 0.333

The upper bound of the confidence interval is 0.43 + 0.097 = 0.527

Therefore, the 95% confidence interval for the total percentage of national park visitors who support supporting endangered species is approximately 33.3% to 52.7%.

The shop initially has 0.884 jars of jam

The probability that both customers chose strawberry jam, is 0.25.

a) Let's assume the number of jars of strawberry jam is 3x and the number of jars of raspberry jam is x.

So, the total number of jars of jam in the shop is 3x + x = 4x.

According to the given information, the probability that both customers select strawberry jam is 11/20.

So, the probability of the first customer selecting a jar of strawberry jam = (3x/4x) = 3/4,

and the probability of the second customer

=  ((3x-1)/(4x-1)).

Now, (3/4) ((3x-1)/(4x-1)) = 11/20

(3/4) ((3x-1)/(4x-1)) = 11/20

20(3/4) ((3x-1)/(4x-1)) = 11

15 (3x-1) = 44  (4x-1)

45x - 15 = 176x - 44

176x - 45x = 44 - 15

131x = 29

x ≈ 29/131

Therefore, the value of x is 0.221

To find the initial number of jars of jam in the shop, we can substitute this value of x into the equation:

4x =  0.884

b) The probability of the first customer selecting strawberry jam is

= (3x)/(4x)

= 3/4.

Therefore, the probability that both customers chose strawberry jam is:

= (3/4) x ((3x-1)/(4x-1))

= (3/4)  ((3 x 0.221 - 1)/(4 x 0.221 - 1))

Simply use BODMAS or BIDMAS; this is the order of your operations. It is an acronym that tells you what to do in what order

Brackets: there are no brackets, move on to indices/order

Indices/Order: for the first step, do 5^2, which is 25, and √49, which is 7. The equation is no 12-5*9(7)-25

Division/Multiplication: For this step, multiply 5, 9 and 7 to get 315. The equation is now 12-315-25

Addition/subtraction: For the final step, just solve 12-315-25 in the traditional left to right way, which is -328.

I have grouped addition and subtraction as well as division and multiplication together because they are done at the same time; if a question has either both addition and subtraction or division and multiplication, just solve these parts from left to right.

From the first equation, we have[tex]b = \frac{2}{5} \times g[/tex]

Step 2: Substitute the expression for [tex]\bold{b}[/tex] into the second equation

Replace [tex]b[/tex] in the second equation with the expression we found in step 1.

[tex]\frac{2}{5} \times g + g = 42[/tex]

Step 3: Solve for [tex]\bold{g}[/tex]

Now, we have an equation with only one variable, [tex]g[/tex]:

[tex]\frac{2}{5} \times g + g = 42[/tex]

To solve for [tex]g[/tex], first find a common denominator for the fractions:

[tex]\frac{2}{5} \times g + \frac{5}{5} \times g = 42[/tex]

Combine the fractions:

[tex]\frac{7}{5} \times g = 42[/tex]

Now, multiply both sides of the equation by [tex]\frac{5}{7}[/tex] to isolate [tex]g[/tex]:

Step 4: Find the value of [tex]\bold{b}[/tex]

Now that we have the value of [tex]g[/tex], we can find the value of [tex]b[/tex] using the first equation:

So, there are 12 boys and 30 girls in the class.

Answer: The rental cost of each movie is $2 and each video game is approximately $5.5

Step-by-step explanation:

Let's assume the rental cost per movie is "m" and the rental cost per video game is "v". We can set up a system of linear equations based on the given information.

From the first month:

5m + 2v = 21 ----(1)

From the second month:

3m + 8v = 50 ----(2)

To solve the system of equations:

5m + 2v = 21 ----(1)

3m + 8v = 50 ----(2)

We can multiply equation (1) by 4 to make the coefficients of "m" the same:

4(5m + 2v) = 4(21)

20m + 8v = 84 ----(3)

Now, subtract equation (2) from equation (3):

(20m + 8v) - (3m + 8v) = 84 - 50

20m - 3m + 8v - 8v = 34

17m = 34

Divide both sides of the equation by 17:

m = 34 / 17

m = 2

Now that we have the value of "m," we can substitute it back into either equation (1) or (2) to solve for "v." Let's use equation (1):

5(2) + 2v = 21

10 + 2v = 21

2v = 21 - 10

2v = 11

v = 11 / 2

v = 5.5

Therefore, the solution to the system of equations is:

m = 2 and v = 5.5

The tangent from the external point are equal, so the x value is 3 units.

7) The measure of the arc XW is 180-105=75

8) The measure of the arc VWY is 105+75+85 = 265

9) We know that, tangent from the external point are equal

In circle C, AB=AD

26=8x+2

8x=24

x=24/8

x=3 units

10) 9x-3=7x+5

9x-7x=5+3

2x=8

x=8/2

x=4

Therefore, the tangent from the external point are equal, so the x value is 3 units.

Answer:

3

Step-by-step explanation:

To find the z-score for a data value of 155 in a normal distribution with a mean of 137 and a standard deviation of 6, you can use the formula:

z = (x - μ) / σ

where:

x is the data value,

μ is the mean, and

σ is the standard deviation.

Plugging in the values, we have:

z = (155 - 137) / 6

Calculating this expression:

z = 18 / 6 = 3

The translated coordinates are:

A: A'(-6, -5)  ⇒ A''(-3,-7)

B:  D'(2,-5)  ⇒  D''(8, -7)

C: C (2, 0)   ⇒ C'(5, -2)

D: D(5,-5)    ⇒ D'(8, -7)

E; C'(-1,0)     ⇒ C''(2, -2)

F: A (-3,-5)   ⇒ A'(0, -7)

G: B'(-5, 0 ) ⇒  B''(-2, -2)

H: B (-2, 0)  ⇒  B'(1, -2)

Here,

We have to apply a translation of 2 units down and 3 units right to these coordinates.

Translation means moving the entire polygon in a particular direction by a certain distance.

To apply the translation,

Add the same amount of distance to the x-coordinate of each vertex for the rightward motion, and subtract the same amount of distance from the y-coordinate of each vertex for the downward motion.

In this case,

the translation is 2 units down and 3 units right.

So the new coordinates will be:

A: A'(-6, -5) ⇒ A'( -6+ 3, -5-2)

              = A''(-3,-7)

B:  D'(2,-5)  ⇒ D'(5+3, -5 -2 )

                  = D''(8, -7)

Similarly apply for each coordinates we get,

C: C (2, 0)   ⇒ C'(5, -2)

D: D(5,-5)    ⇒ D'(8, -7)

E; C'(-1,0)     ⇒ C''(2, -2)

F: A (-3,-5)   ⇒ A'(0, -7)

G: B'(-5, 0 ) ⇒  B''(-2, -2)

H: B (-2, 0)  ⇒  B'(1, -2)
