Answer:

24 is 3/4 of 32.

Step-by-step explanation:

if you understand:

24 divided by 3 (3 in 3/4) is 8.

8 x 3 = 24, so if we need to fill in the extra 1 in 3/4 (making it 4/4), we would need to add another 8. 24 + 8 = 32. (u can look up ' what is 3/4 of 32 too ')

Answer:

look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.

given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°

now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°

Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180

aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°

Answer: The correct option is A.

Step-by-step explanation:

To calculate the distance between the points, we use the formula:

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

where,

d= distance

\(x_2\text{ and }x_1\) are the coordinates of the points on x-axis

\(y_2\text{ and }y_1\) are the coordinates of the points on y-axis

For the given points:

A(-4,3), B(2,5), C(3,2) and D(-3,0)

\(x_2=3\\x_1=-3\\y_2=2\\y_1=0\)

Putting values in above equation, we get:

\(CD=\sqrt{(3-(-3))^2+(2-0)^2}\\\\d=\sqrt{36+4}=6.32units\)

\(x_2=-4\\x_1=-3\\y_2=3\\y_1=0\)

Putting values in above equation, we get:

\(AD=\sqrt{(-4-(-3))^2+(-3-0)^2}\\\\d=\sqrt{1+9}=3.16units\)

To calculate the area of a reactangle, we use the equation:

\(Area=l\times b\)         ....(1)

where,

l = length of the rectangle = CD = 6.32 units

b = breadth of the rectangle = AD = 3.16 units

Putting values in equation 1, we get:

\(Area=6.32\times 3.16\\\\Area=20.0 \text{ square units}\)

Hence, the correct option is A.

Answer:

8cosx-cosy=8.

Step-by-step explanation:

dy/dx=8sinx/siny;

sinydy=8sinxdx;

-cosy= -8cosx+C;

according to the condition y(0)=pi/2:

-cos(pi/2)= -8cos0+C;

-8+C=0; ⇔ C=8, then

8cosx-cosy=8.

The solution to the given initial-value problem y' = (8 sin(x))/sin(y) with the given condition y(0) = π/2 is equal to y = -cos⁻¹(x).

To solve the initial-value problem y' = (8 sin(x))/sin(y) with the initial condition y(0) = π/2, separate variables and then integrate.

Separate variables.

y' = (8 sin(x))/sin(y). To separate variables, multiply both sides by sin(y) and divide by (8 sin(x)):

sin(y) dy = dx

Integrate both sides.

Now, integrate both sides of the equation with respect to their respective variables:

∫sin(y) dy = ∫dx

Integrating the left side:

∫sin(y) dy = -cos(y) + C₁ (where C₁ is the constant of integration)

Integrating the right side:

∫dx = x + C₂ (where C₂ is the constant of integration)

Apply initial condition.

Now, apply the initial condition y(0) = π/2 to find the values of C₁ and C₂:

When x = 0, y = π/2

cos(π/2) + C₁ = 0 (substitute y = π/2 into -cos(y) + C₁)

C₁ = 0 (since cos(π/2) = 0)

So, the equation becomes:

-cos(y) = x + C₂

Solve for y.

Now, isolate y on one side of the equation:

y =-cos⁻¹(x + C₂)

Find C₂ using the initial condition.

Now, use the initial condition y(0) = π/2 to find C₂:

When x = 0, y = π/2

π/2 = -cos⁻¹(0 + C₂)

cos⁻¹(C₂) = -π/2

C₂ = cos(-π/2) = 0

Final solution.

Finally, substitute C₂ = 0 into the equation y = -cos⁻¹(x + C₂) to get the final solution:

y = -cos⁻¹(x)

Therefore, the solution to the initial-value problem y' = (8 sin(x))/sin(y) with y(0) = π/2 is y = -cos⁻¹(x).

Answer:

a) \(\frac{19}{52}\)

b) \(\frac{7}{52}\)

Step-by-step explanation:

Total number of students = 52

Number of students who are democrats = 26

Number of students who are business majors = 12

Number of students who are business majors as well as democrats = 7

Now, lets come to the question.

a) Number of students who are democrats but not business majors =

(Number of democrats) - (Number of democrats as well as business majors)

⇒ 26 - 7

⇒ 19

∴ P (Democrat who is not a business major) = \(\frac{19}{52}\)

b) Number of students who are neither democrats nor business majors =

(Total number of students) - (Number of democrats + Number of business majors + Number of democrats as well as business majors)

⇒ 52 - (26 + 12 + 7)

⇒ 52 - 45

rabbits       2    3     5     7     11    15     18    22    27

the formula of quartiles is

Lower Quartile (Q1) = (N+1) * 1 / 4

Middle Quartile (Q2) = (N+1) * 2 / 4

Upper Quartile (Q3 )= (N+1) * 3 / 4

here N = 9

third quartile(Q3) = (N+1) * 3 / 4

third quartile(Q3) = (9 + 1)3/4

third quartile(Q3) = 7.5 term

third quartile(Q3) is the term between 7th and 8th week

third quartile(Q3) = (7th term + 8th term)/2

7th term = 18

8th term = 22

third quartile(Q3) = (18 + 22)/2

third quartile(Q3) = 20

6. Number of athletes own a TV or a store, but not a convertible = 13 + 34 +71

= 118.

The number of athletes did not own any of the three items need to subtract the number of athletes who own at least one item from the total number of athletes surveyed.

Total number of athletes surveyed = 259

Number of athletes own at least one item = 110 + 91 + 120 - 15 - 43 - 44 + 9 = 228

Number of athletes who did not own any of the three items = 259 - 228 = 31.

The number of athletes who owned a convertible and a TV but not a store need to subtract the number of athletes who own all three items from the number of athletes who own a convertible and a TV.

Number of athletes who own a convertible and a TV = 44

Number of athletes who own all three items = 9

Number of athletes who own a convertible and a TV but not a store = 44 - 9 = 35

The number of athletes who owned a convertible, or a TV need to add the number of athletes who own a convertible to the number of athletes who own a TV and then subtract the number of athletes own both a convertible and a TV.

Number of athletes who own a convertible or a TV = 110 + 91 - 44

\( \huge \boxed { - 3}\)

Step-by-step explanation:

The graph intercepts x-axis at (-3,0). Therefore x-intercept is - 3.

The difference between the selling price and the cost price is the profit he earned.

Profit = Selling Price - Cost Price

Profit = $216 - $180

Profit = $36

To find the percentage profit, we need to calculate what proportion of the cost price the profit represents, and express that as a percentage :

Percentage Profit = (Profit : Cost Price) * 100%

Percentage Profit = ($36 : $180) * 100%

Percentage Profit = 0.2 * 100%

Percentage Profit = 20%

Therefore, his percentage profit is 20%.

The probability that the population percentage would differ from the sample proportion of flops in a sample of 407 released films by less than 3% is roughly 0.8354, rounded to four decimal places.

For the trials we are looking at, the probability of receiving a success in a binomial distribution must stay constant. Since there are only two possible outcomes when tossing a coin, for instance, the probability of flipping a coin is 12 or 0.5 for each experiment we conduct.

To determine the likelihood that the sample proportion of flops is within 3% of the population proportion, we need to know the chance that |p - 0.09| 0.03.

We can suppose that the sample proportion's distribution is

approximately normal with mean μ = 0.09 and standard deviation σ = √((0.09)(0.91)/407)

≈ 0.017.

We may calculate the z-scores for the top and lower boundaries of the interval using the conventional normal distribution:

z1 = (0.06 - 0.09) / 0.017 ≈ -1.76

z2 = (0.12 - 0.09) / 0.017 ≈ 1.76

The probability between these two z-scores is represented by the region beneath the standard normal curve:

P(-1.76 < Z < 1.76)

= 0.9177 - 0.0823

= 0.8354

The equation of the ellipse is \((x - 3)^2 / 16 + (y - 3)^2 / 64 = 1.\)

To determine the equation of the ellipse, we need to find its major and minor axes, as well as the distance from each focus to the center.

Given that the foci of the ellipse are located at (3, 1) and (3, 5), we can determine that the center of the ellipse is at the midpoint between these two foci, which is (3, 3).

The endpoints of the minor axis are (7, -2) and (-1, -2), which tells us that the length of the minor axis is 7 - (-1) = 8 units.

Now, let's calculate the distance from the center to one of the foci. Using the distance formula, we have:

sqrt((3 - 3)^2 + (3 - 1)^2) = sqrt(0 + 4) = 2.

Since the foci are vertically aligned, the major axis is vertical. Therefore, the length of the major axis is twice the distance from the center to one of the foci, which gives us 2 \(\times\) 2 = 4 units.

Using the standard form of the equation for an ellipse centered at (h, k), with a horizontal major axis of length 2a and a vertical minor axis of length 2b, the equation is:

\((x - 3)^2 / 4^2 + (y - 3)^2 / 8^2 = 1.\)
