The measure of the angle ABC from the diagram is equivalent to 78 degrees.

We need to find <ABC

Let us produce BA to meet PR at point G.

It is given that BG || PQ

Thus, <RGB and <QPR are corresponding angles.

This shows that <RGB = <QPR since they are corresponding angles.

On the other hand, <QPR = 102 degrees and <ABC are <RGB consecutive interior angles, then:

<ABC + <RGB = 180

<ABC + 102 = 180

<ABC = 180 - 102

<ABC = 78 degrees

Hence the measure of the angle ABC from the diagram is 78 degrees.

The value of c that satisfies the conclusion of the mean value theorem is c≈7.69.

The mean value theorem states that if a function f(x) is continuous on a closed interval [a,b] and differentiable on the open interval (a,b), then there exists at least one point c in (a,b) where the value of the derivative of f(x) is equal to the slope of the line connecting the endpoints of the interval, i.e., \(f'(c)=(f(b)-f(a))/(b-a).\)

Here, the function \(f(x)=x^(3/4)\) is continuous on the closed interval [0,16] and differentiable on the open interval (0,16), as the derivative of f(x) is \(f'(x)=(3/4)x^(-1/4)\), which is defined for all x in (0,16).

Therefore, we can apply the mean value theorem to this function on the interval [0,16].

To find the value of c that satisfies the conclusion of the mean value theorem, we first calculate the slope of the line connecting the endpoints of the interval: \((f(b)-f(a))/(b-a)=[(16)^(3/4)-(0)^(3/4)]/(16-0)\)=\(2sqrt(2).\) Then, we set f'(c)=2sqrt(2) and solve for c:

\(f'(c)=(3/4)c^(-1/4)=2sqrt(2)c^(-1/4)=(8/3)sqrt(2)c=(3/2)^(4/3)≈7.69\)

Therefore, the value of c that satisfies the conclusion of the mean value theorem is c≈7.69.

The values of a and b for the probability density function are a = 56 and b = 216.

According to the given information, the mean daily spending by Americans earning over $90,000 per year was $136 per day, and the probability density function is given by f(x) = 0.00625 for a ≤ x ≤ b.

To find the values of a and b for the probability density function, we can use the formula for the mean of a uniform distribution:

mean = (a + b)/2

Substituting the given mean value of $136 into the formula, we get:

136 = (a + b)/2

Multiplying both sides of the equation by 2, we get:

272 = a + b

Rearranging the equation, we get:

b = 272 - a

Now, we can use the formula for the area under the probability density function, which is equal to 1:

∫_a^b f(x) dx = 1

Substituting the given probability density function and the value of b into the formula, we get:

∫_a^(272-a) 0.00625 dx = 1

Simplifying the integral, we get:

0.00625(272 - 2a) = 1

Dividing both sides of the equation by 0.00625, we get:

272 - 2a = 160

Rearranging the equation, we get:

2a = 112

Dividing both sides of the equation by 2, we get:

a = 56

Substituting the value of a back into the equation for b, we get:

b = 272 - 56 = 216

Step-by-step explanation:

To solve this problem, we need to find the scale factor that will allow us to enlarge the 12" x 9" painting to fit the 24' x 16' wall.

First, we need to convert all the units to the same system. Let's convert the painting size to feet:

12 inches = 1 foot (since there are 12 inches in a foot)

9 inches = 0.75 feet (since 9/12 = 0.75)

So the size of the painting in feet is 1 foot by 0.75 feet.

Next, we can find the scale factor by dividing the size of the wall by the size of the painting:

Scale factor = (24 feet) / (1 foot) = 24

Scale factor = (16 feet) / (0.75 feet) = 21.33 (rounded to two decimal places)

We use the smaller of the two scale factors, which is 21.33, to ensure that the painting will fit within the dimensions of the wall.

Finally, we can find the size of the enlarged painting by multiplying the original size by the scale factor:

Width of enlarged painting = 1 foot x 21.33 = 21.33 feet

Height of enlarged painting = 0.75 feet x 21.33 = 15.99 feet

Therefore, the largest possible complete design that can be painted on the 24' x 16' wall is approximately 21.33 feet by 15.99 feet, using a scale factor of 21.33.

Answer:

the largest possible complete design that can be painted on the 24' x 16' wall is 21' x 15.75'

Step-by-step explanation:

Here, the double prime (double commas) ('') mean inches and the single prime(single comma) (') means foot.

So, the painting is (12" )(9") so it is 12 inches by 9 inches.

While the wall is (24')(16') so it is 24 feet by 16 feet.

We have to find the largest possible complete design that can be painted on the wall

Now, since 12 inches = 1 foot

And for the design to be complete, the design must fit on the wall

now, for every 12 inches we add to the height (the first part i.e 24)

We add 9 inches to the width (the 2nd part i.e. 16)

starting from one side,

we have,

(12 inch)(9 inch) = (1 feet)(9/12 feet)

(12 inch)x(9 inch) = (1 feet)x(3/4 feet)  (i)

where we get the 2nd term, 9/12 as follows,

Since,

\(12 \ inches = 1 foot\\so, \\1 \ inch = (1/12) feet\\and,\\9 \ inches = 9/12 \ feet\)

Now, 9/12 = 3/4

so, 9 inches = 3/4 feet

We have obtained the required ratio, we just now check how far this ratio can go until we exceed the limit of the wall, 24 feet by 16 feet,

so, for example,

Now, this means that when we increase the height by 12 inches = 1 foot,

we also have to increase the width by 3/4 feet = 9 inches

so, if we muliiply the height by 2, we also multiply the width by 2 to get,

(24 inch)x(18 inch) = (2 ft) x (3/2 ft)

now, (2 ft) x (3/2 ft) is smaller than (24 ft) x (16 ft),

Similarly, If we multiply the height by 24, we also have to multiply the width by 24, in which case we get,

24 ft by 24(3/4)ft

(24 ft) x (18 ft) which is greater than the allowed, (24 ft) x (16 ft) (i.e. 18 > 16)so this design cannot fit on the wall

(24 ft) x (18 ft) cannot be painted on the wall since the wall is smaller,

Trying 23, we get,

(23 ft) x (23(3/4) ft) = (23 ft) x (17.25 ft) which is still greater

so we try 22,

(22 ft) x (22(3/4) ft) = (22 ft) x (16.5 ft) which is Still greater

We try 21 to get,

(21 ft) x (21(3/4) ft) = (22 ft) x (15.75 ft) Which is smaller than the wall

So, the largest possible complete design that can be painted on a 24' x 16' wall is 22' x 15.75'

Doing this in another way,

1 inch = 1/12 feet

9 inches = 3/4 feet

We have to find the greatest possible ratio between the height and width of the painting that can be fitted on the wall,

the ratio is height/width = 12 inches/9 inches = 1 ft/(3/4 ft)

and this has to be the greatest ratio less than 24 ft/(16 ft)

If we multiply and divide the ratio by 21, we get,

\(21 \ ft/((21)(3/4\ ft))\)

which gives,

21 ft/ 15.75 ft

or in the other form, the painting is 21' x 15.75' < 24' x 16' (both 21' < 24' and 15,75' < 16')

But if we multiply by 22,

we get

22 ft /(22)(3/4) ft  

in the other form, the ratio is 22' x 16.5'

but since 16.5' is greater than 16',

the 22' x 16.5' design cannot be painted on the wall ( the wall has too little width 16' instead of 16.5')

So, the largest possible complete design that can be painted on the 24' x 16' wall is 21' x 15.75'

(a) To find the number of cars entering the parking garage over the interval 0 ≤ t ≤ 10, we need to integrate the rate of cars entering the garage with respect to time. ∫58cos(0.1635t - 0.642)dt from 0 to 10 gives approximately 822.6 cars.
(b) To find ′′(5), we need to differentiate the rate of cars leaving the garage with respect to time twice. ′′(t) = -65cos(0.281) and ′′(5) = -65cos(0.281) which is approximately -62.4 cars per hour per hour. This value represents the rate of change of the rate of cars leaving the garage at t = 5.
(c) To find the number of cars in the parking garage at time t = 10, we need to subtract the total number of cars leaving the garage from the total number of cars entering the garage from t = 0 to t = 10. This gives approximately 559 cars in the garage at t = 10.

There are 210 different committees that can be formed by selecting 6 people from a list of 10 people.

What is the combination?

Combinations are a way to count the number of ways to choose a subset of objects from a larger set, where the order of the objects does not matter.

To calculate the number of different committees that can be formed, we can use the concept of combinations.

In this case, we want to select 6 people from a list of 10 people, and the order in which the committee members are selected does not matter.

The formula for combinations is given by:

C(n, r) = n! / (r! * (n - r)!)

where C(n, r) represents the number of combinations of selecting r items from a set of n items, and ! denotes factorial.

Using this formula, we can calculate the number of different committees that can be formed:

C(10, 6) = 10! / (6! * (10 - 6)!)

Simplifying:

C(10, 6) = 10! / (6! * 4!)

10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

6! = 6 * 5 * 4 * 3 * 2 * 1

4! = 4 * 3 * 2 * 1

Substituting these values:

C(10, 6) = (10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) / ((6 * 5 * 4 * 3 * 2 * 1) * (4 * 3 * 2 * 1))

C(10, 6) = (10 * 9 * 8 * 7) / (4 * 3 * 2 * 1)

C(10, 6) = 210

Therefore, there are 210 different committees that can be formed by selecting 6 people from a list of 10 people.

Using the concept of Randomized Design ,we got 4 levels of treatment heave been done by farmer in this experiment.

1.Completely Randomized Design :-

A completely randomized design is basically the simplest experimental design, in terms of data analysis and convenience. With this design, subjects are randomly assigned to treatments.

This completely randomized design actually relies on randomization to control for the effects of extraneous variables. The experimenter actually assumes that, on average, extraneous factors will affect treatment conditions equally; so any relevant differences between conditions can fairly be attributed to the independent variable.

2.Double Blind Design :-

In an experiment, if subjects in the control group knows that they are receiving a placebo, the placebo effect will be reduced or will be eliminated; and the placebo will not serve its intended control purpose.

Blinding is basically the practice of not telling subjects whether they are receiving a placebo. In this way, subjects which are in the control and treatment groups experience the placebo effect equally. Often, knowledge of which groups receive placebos is also keep from analysts who evaluate the experiment. This practice is called double blinding. It prevents the analysts from "spilling the beans" to the subjects through subtle cues; and it assures that their evaluation is not tainted by the awareness of actual treatment conditions.

3.Matched Pairs Design :-

A matched pairs design is actually a special case of a randomized block design. It can be used when the experiment has basically only  two treatment conditions; and subjects can be grouped into pairs, on the basis of some blocking variable. Then, within each pair, subjects are randomly assigned to different treatments.

4.Randomized Block Design :-

With a randomized block design, the experimenter actually divides subjects into subgroups called blocks, such that the variability within blocks will become  less than the variability between blocks. Then, subjects within each block are randomly assigned to treatment conditions.

Hence, we got 4 levels of treatment have been done by farmer in this experiment.
