a) Observed: 42 Expected: 22.5

B) Observed: 42 Expected: 24

C) Observed: 57 Expected: 24

D) Observed: 57 Expected: 22.5

Answers

The observed frequency = 42, and the expected is 22.5.

option A.

What is the observed and expected frequencies?

The observed and expected frequencies for the boys participating in soccer is calculated as follows;

Total boys = 18 + 42 + 12 = 72

Total girls = 30 + 15 + 18 = 63

Total number of the students = 72 + 63 = 135

Ratio of boys = 72/135 = 0.533

Ratio of girls = 63 / 135 = 0.467

The observed and expected frequencies for the boys participating in soccer is calculated as follows;

Expected frequency = 0.534 x 42

= 22.4

Thus, the observed frequency = 42, and the expected is 22.5.

#SPJ1

Answer:

Observed: 42

Expected: 24

Step-by-step explanation:

If we simply go to the chart then we can directly see the observed frequency for boys participating in soccer is 42.

To find the expected frequency, we need to find the number of occurrences if the null hypothesis is true, which in this case, was that the three options are equally likely, or if the three options were all evenly distributed.

First, add up all the options in the boys column:

18 plus 42 plus 12 equals 72

If each of these three options were evenly distributed among the 72 boys, we would need to divide the total evenly between the three options:

72 divided by 3 equals 24

This means we would expect 24 boys to choose tennis, 24 boys to choose soccer, and 24 boys to choose swimming.

Find the x intercepts of the parabola with vertex (-1,2) and y intercept (0,3).

Answers

The x intercepts of the parabola with  vertex (-1,2) and y intercept (0,3) does not exist

Finding the x intercepts of the parabola

From the question, we have the following parameters that can be used in our computation:

vertex (-1,2) and y intercept (0,3).

A parabola is represented as

y = a(x - h)² + k

Where

Vertex = (h, k)

Using the above as a guide, we have the following:

y = a(x + 1)² + 2

Also, we have

a(0 + 1)² + 2 = 3

So, we have

a = 1

This means that

y = (x + 1)² + 2

Set to 0 to calculate the x-intercepts

(x + 1)² + 2 = 0

This gives

(x + 1)² = -2

Take the square root

(x + 1) = comple numbers

B y = -1/3x + 8
C y= 1/3x + 4
D y= 3x - 12

Answers

Answer:

C. y = 1/3x + 4

Step-by-step explanation:

To find the equation of the line that passes through the given points, we can use the slope-intercept form of the equation of a line, which is:

y = mx + b

where m is the slope of the line and b is the y-intercept.

To find the slope of the line, we can use the formula:

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

where (x1, y1) and (x2, y2) are any two points on the line. We can choose the points (x1,y1) = (-3,3) and (x2,y2) = (6,6) from the table.

m = (6 - 3) / (6 - (-3)) = 3/9 = 1/3

Now that we have the slope, we can use the point-slope form of the equation of a line to find the y-intercept:

y - y1 = m(x - x1)

where (x1,y1) is any point on the line. We can choose the point (x1,y1) = (3,5) from the table.

y - 5 = (1/3)(x - 3)

Now we can solve for y to get the equation in slope-intercept form:

y = (1/3)x + (5 - 1/3*3)

y = (1/3)x + 4

Therefore, the equation of the line that passes through the given points is C) y= 1/3x + 4.

Answers

Investment B is an ordinary  subvention with$ 3,906.64 in the account after one time. The correct answer is option d.    

To determine which investment is an ordinary  subvention and the  unborn value after one time, we first need to understand that an ordinary  subvention is a series of equal payments made at the end of each period.

Given the table, we can see that Investment A has payments starting in January and ends in November( missing December), while Investment B starts in February and ends in December.

thus, Investment B is the ordinary  subvention since the payments are made at the end of each month.  Now let's calculate the  unborn value of Investment B after one time  

1. Convert the periodic interest rate to a yearly rate( 10.035)(1/12)- 1 ≈0.002867

2. Determine the number of payments made 11 months  3. Use the  unborn value of  subvention formula FV =  P *(( 1 r) n- 1)/ r  

Where P =  yearly payment($ 350),

r =  yearly interest rate(0.002867), and n =  number of payments( 11) . Plug in the values

FV =  350 *(( 10.002867) 11- 1)/0.002867 ≈3906.64  

So, Investment B is an ordinary  subvention with$ 3,906.64 in the account after one time. The correct answer is optiond.

Where:

x and y represent the data points.m represent the slope.

First of all, we would find the slope of function B;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-1 + 2)/(3 - 0)

Slope (m) B = 1/3.

At data point (0, -1) and a slope of 1/3, function B can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

The table shows how many Calories Lance burns jogging on a treadmill for different lengths of time. Lance's goal today is to burn 380 Calories. If he has been jogging for 25.5 minutes, for how many more minutes does he still need to jog? Assume the situation is proportional.

Answers

Lance needs to jog for an additional 316.08-25.5 = 290.58  minutes to burn 380 Calories.          

The information given in the table to  produce a direct equation that relates the number of Calories burned to the time spent jogging. Let's use the  pitch- intercept form y =  mx b, where y represents the number of Calories burned( in hundreds), x represents the time spent jogging( in  twinkles), m represents the rate of Calories burned( in hundreds per  nanosecond), and b represents the  original Calories burned( in hundreds).  To find m, we can use the points( 10, 13) and( 15, 19), which represent two ordered  dyads on the line. We can find the  pitch of the line using the  pitch formula  

m = ( y2- y1)/( x2- x1)  m = ( 19- 13)/( 15- 10)  

m = 1.2  So the equation for the line is  y = 1.2 x b.

 To find b, we can use the point

( 10, 13)  = 1.2( 10) b  b = 0.7

 So the complete equation for the line is  y = 1.2 x0.7  Now we can use this equation to  break for x, the number of  twinkles Lance needs to jog to burn 380 Calories.  

380 = 1.2 x0.7  = 1.2 x  x = 316.08

So Lance needs to jog for an additional 316.08-25.5 = 290.58  minutes to burn 380 Calories.

While browsing at her local farmers' market, Lexi stops at a booth selling fancy candles and hand soaps. She has

Graph the inequality that represents how many candles, x, and hand soaps, y, Lexi can buy.
Plot points on the boundary line. Select the line to switch between solid and dotted. Select a region to shade it.

Answers

The graph represents the valid region of the number of candles and hand soaps that Lexi can buy with her $50 budget.

To shade the region that satisfies the inequality, we need to determine which side of the line represents the valid region. Since the inequality is less than or equal to, the valid region is the one below the line.

Let x be the number of candles that Lexi buys and y be the number of hand soaps that she buys. The cost of x candles is 12.50x and the cost of y hand soaps is 5y. Lexi has $50 to spend, so we can write the following inequality:

12.50x + 5y ≤ 50

To graph this inequality, we first need to graph the boundary line, which is the equation obtained by replacing the inequality sign with an equal sign:

12.50x + 5y = 50

We can rewrite this equation in slope-intercept form as:

y = -2.50x + 10

To plot points on the boundary line, we can choose any two values of x and solve for the corresponding values of y. For example, if we let x = 0, then y = 10, so one point on the line is (0,10). If we let x = 4, then y = 0, so another point on the line is (4,0).

We can now graph the boundary line, which has a slope of -2.50 (meaning it goes down and to the right) and a y-intercept of 10 (meaning it intersects the y-axis at the point (0,10)). To switch between a solid and dotted line, select the "solid line" or "dotted line" option in the graphing tool.

2/5 = (2 * y)/(5 * y) = 2y/5y

Next, we'll rewrite 4/y as an equivalent fraction with the denominator 5y:

4/y = (4 * 5)/(y * 5) = 20/5y

Now, we can rewrite the expression with the common denominator 5y:

2y/5y - 20/5y + 3

Since the denominators are now the same, we can combine the numerators:

(2y - 20 + 3 * 5y)/(5y)

Simplifying further:

(2y - 20 + 15y)/(5y) = (17y - 20)/(5y)

Thus, the expression 2/5 - 4/y + 3 can be expressed as a single fraction: (17y - 20)/(5y).

If m d=18 and m c = 45 what is m bc

Answers

The measure of angle BC is 27 degrees.

To find the measure of angle BC, we need to use the angle sum property of triangles. In triangle ABC, the sum of all angles is equal to 180 degrees. We know that angle ACD is a straight angle and therefore measures 180 - 45 = 135 degrees.

Additionally, we know that angle ADB is also a straight angle and therefore measures 180 - 18 = 162 degrees.

To find angle BCD, we subtract the measure of angle ACD from the measure of angle ADB, which gives us:

m BCD = m ADB - m ACD
m BCD = 162 - 135
m BCD = 27 degrees

A plumber charges fixed and per hour. He did a job for a neighbor for 3 hours, he charged $140. To another
neighbor the plumber charged him $232 for 7 hours.

1.Find out how much he charges per hour
2. how much fixed rate
3. the equation that tells how much the plumber earns.
4. how much would you earn if you worked 5.75 hours

Answers

The plumber charges $23 per hour, the plumber charges a fixed rate of $71 and If someone worked for 5.75 hours, their earnings would be $203.25

To find the plumber's hourly rate, we can use the given information and set up two equations:

3h + f = 140 (where h is the hourly rate and f is the fixed rate for the first job)

7h + f = 232 (where h is the hourly rate and f is the fixed rate for the second job)

We can solve for h by subtracting the first equation from the second equation:

4h = 92

h = 23

Therefore, the plumber charges $23 per hour.

To find the plumber's fixed rate, we can substitute h = 23 into one of the equations and solve for f:

3h + f = 140

3(23) + f = 140

69 + f = 140

f = 71

Therefore, the plumber charges a fixed rate of $71.

The equation that tells how much the plumber earns can be written as:

Earnings = (hourly rate x number of hours) + fixed rate

or E = 23h + 71

If someone worked for 5.75 hours, their earnings would be:

Earnings = (hourly rate x number of hours) + fixed rate

Earnings = (23 x 5.75) + 71

Earnings = 132.25 + 71

Earnings = $203.25

Answers

The right Riemann sum is an overestimate.

The left Riemann sum is an underestimate.

For n=2, the interval [0,1] is divided into 2 subintervals of equal width, so Δx = (1-0)/2 = 1/2.

Left Riemann Sum with n=2:

The left endpoints of the subintervals are x=0 and x=1/2.

f(0) = e⁰ = 1

f(1/2) = [tex]e^1^/^2[/tex]

So, the left Riemann sum is:

Δx[f(0) + f(1/2)] = (1/2)[1 +[tex]e^1^/^2[/tex]] = (1/2) + (1/2)[tex]e^1^/^2[/tex]

sum = (1/2) + (1/2)[tex]e^1^/^2[/tex]

Right Riemann Sum with n=2:

The right endpoints of the subintervals are x=1/2 and x=1.

f(1/2) = [tex]e^1^/^2[/tex]

f(1) = e¹ = e

So, the right Riemann sum is:

Δx[f(1/2) + f(1)] = (1/2)[[tex]e^1^/^2[/tex] + e] = (1/2)[tex]e^1^/^2[/tex] + (1/2)e

sum = (1/2)[tex]e^1^/^2[/tex]+ (1/2)e

Since [tex]e^1^/^2[/tex] > 1, the right Riemann sum is an overestimate, and the left Riemann sum is an underestimate.

The given expression; = (27 · 3  -  1719 ÷ 1719) ÷ 8 + 5² - 3³  + (8 · 4  -  2·13)

We will simplify the expression as follows;

(27 · 3  -  1719 ÷ 1719) = (81  -  1719/1719) = (81 - 1) = 80

(8 · 4  -  2·13) = (32  -  26) = 6

= 80 ÷ 8 + 5² - 3³  + 6

= (80/8) +  5² - 3³  + 6

= 10 +  5² - 3³  + 6

= (10 + 5² + 6) - 3³

= 41 - 27
