By using the travel distance formula, we found out that it takes 1 hour for the car and the truck to meet if they leave at the same time and travel toward each other.

It is given to us that -

Two cities are 145 miles apart

Truck travels this distance in 2.5 hours

Car is 1.5 times as fast as the truck

We have to find out the time taken for the car and the truck to meet if they leave at the same time, and travel toward each other.

We know that -

[tex]Speed = \frac{Distance}{Time}[/tex] ----- (1)

Let us say that the speed of the truck is given by [tex]S_{t}[/tex] and the speed of the car is given by [tex]S_{c}[/tex].

Now, from equation (1), we can say that the speed of the truck,

[tex]S_{t}=\frac{145}{2.5} \\= > S_{t}= 58 miles per hour[/tex] ----- (2)

It is given to us that the car is 1.5 times as fast as the truck

=> [tex]S_{c}= 1.5 * 58\\= > S_{c}= 87 miles per hour[/tex] ----- (3)

It is mentioned that the car and the truck leave at the same time to meet each other.

Let us say that the truck meets the car at a distance 'd'.

This implies that the distance travelled by the car to meet the truck at a given point = (145-d)  --- (4)

From equation (1), we can say that

[tex]Time = \frac{Distance}{Speed}[/tex]

Also, we know that -

Time taken by truck to travel d miles = Time taken by car to travel (145-d) miles

[tex]\frac{d}{58}=\frac{145-d}{87} \\= > 87d = 8410-58d\\= > 145d=8410\\= > d = 58[/tex]

Thus, the truck will travel 58 miles to meet car after they leave at the same time.

So, the time taken for the car and truck to meet =

[tex]\frac{58 miles}{58 miles per hour} = 1 hour[/tex]

Therefore, according to the distance formula, it takes 1 hour for the car and the truck to meet if they leave at the same time and travel toward each other.

mean of the data set = sum / frequency

mean = 7.293.

Hence the point of estimate = 7.293

b) Using p-value> q(.80)

p> 1.282

And the sample average is just mean(x)

p>7.2933

So our margin of error is

e <- 1.282*(2.3001/sqrt(15))

e<0.7614

The lower and upper bounds are:

= mean(x) - e = 6.5319

= mean(x) + me = 8.0547

Hence the lower and upper bounds for the p-value will be 6.5319 and 8.0547 .

A statistical calculation known as a p-value is employed to assess the applicability of a hypothesis to the data. A p-value establishes the likelihood that the outcomes that were observed would occur if the null hypothesis were true.

The value of Tim's house at the start of 2018 is £146410

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

Initial value = 100,000

Rate of increase = 10%

The value of the house x years after 2014 can be represented as the following exponential function

Value = Initial value * (1 + rate)ˣ

So, we have

Value = 100000 * (1 + 10%)ˣ

2018 is 4 years after 2014

This means that x = 4

The net present value formula helps us to determine the net present value of boat repair model B14 model by Cleveland Cove enterprises.

so, the net present value is 384,285.714.

Net present value: The net present value is applied to a series of cash flows occurring at different times. The present value of a cash flow always depends on the interval of time between now and the cash flow.

NPV = Rt /(1+i)^t

where , Rt --> net cash flow at time t

i --> discount rate

t --> time of cash flow

We have given that , A company has narrowed their choices down to two: the B14 Model and the F54 Model.

F54 Model :

Residual value , = 18,000

Annual net cash inflow = 30,000

investment = 230,000

time , t = 10

rate of return,r = 12%

B14 Model :

Residual value , = 10,000

Annual net cash inflow = 80,000

investment = 330,000

time , t = 10

rate of return,r = 8%

we have to calculate the net present value for model B14.

so, Net present Value = present value of annually cash - investment

present value of annually cash

= 80000/1.12 = 71,428.571

Net present value =71,428.571 ×10 - 330000

= 714,285.71 - 330,000 = 384,285.714

The proximal tubule reabsorbs all of the filtered glucose and amino acids, as well as salt, chloride, potassium, and bicarbonate. So the option b is correct.

In the given question, we have to check most of the glucose that is filtered through the glomerulus undergoes reabsorption in the:

a. distal tubule

b. proximal tubule

c. descending limp of the loop of Henle

d. ascending limb of the loop of Henle

The proximal tubule reabsorbs all of the filtered glucose and amino acids, as well as salt, chloride, potassium, and bicarbonate. Additionally, sodium ion and glucose were co-transported in the proximal tubule by the co-transporter SGLT (sodium dependent glucose transporter). The ability to transport glucose distinguishes two SGLT (SGLT1 and SGLT2). Since SGLT2 is abundant in the S1 and S2 segments of the proximal tubule and SGLT1 has a high affinity for glucose, it filters 90% of the glucose. Option (b) is correct, therefore.

Option (a) is False, since the distal tubule is crucial to maintaining a healthy acid-base balance. The amount of extracellular fluid is regulated.

The descending limb of the Henle loop, which is involved in reabsorption of salt, urea, and water, makes option (c) incorrect.

Option (d) is likewise untrue because the ascending limb of the loop of Henle allows for the reabsorption of sodium, calcium, bicarbonate, chloride, and magnesium but not glucose.

The probability that a person will buy pop corn and soda is 9/20

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it. Probability can range from 0 to 1, where 0 means the event to be an impossible one and 1 indicates a certain event.

probability = sample space / total possible outcome

The total possible outcome here is 100

The correct answer is the measure of two angles are 37.5° and 22.5°.

It is given that the measure of two angles are in the ratio 5:3 . Let the one angle be 5x and the other angle be 3x.

Difference of the angles = 5x - 3x

According to the question, the measure of the larger angle is 30° greater than half the difference of the angles

Thus we can write it as:

⇒ 5x - 1/2(5x-3x) =30°

⇒ 10x- (5x-3x) = 60°

⇒ 8x =  60°

⇒ x = 7.5°

Thus, the larger angle = 5x = 5×7.5= 37.5° and the smaller angle = 3x = 3× 7.5 = 22.5°

Hence, the measure of two angles are 37.5° and 22.5°.
