Can someone help me with this please?

Answer:

10

Step-by-step explanation:

If the decimal is .5 or above, round up to the next whole number. If the decimal is below .5, round down to the last whole number. Because .7 is greater than .5, we round up to 10.

Answer:

10

Step-by-step explanation:

In rounding, we look at the digit one place to the right of what we are rounding to.  If that digit that is one place to the right is 5 or greater, we increase our digit by one.  If that digit that is one place to the right is 4 or less, we leave our digit as it is.

No because their ratios are different and not equivalent

A Average speed distance of 60 km in 1 hr, 56km in 2hr ,70km in 3hr, 50km in 4hr,65km in 5 hr, 60 km in 6 hr = 14.61 km/hr

Given:

Average speed=Total distance /Total time

60 km in 1 hr,

56km in 2hr ,

70km in 3hr,

50km in 4hr,

65km in 5 hr,

60 km in 6 hr

Average speed=207/21=14.61

The average speed of a body is the mean value of its speed across time. The formula for average speed is required since the speed of a moving body is not constant and fluctuates over time. Even with changing speed, the values of total time and total distance traversed may be employed, and we can get a single number to describe the complete motion using the average speed calculation.

A body's average speed is equal to the overall distance traveled divided by the entire time spent. The average speed formula is as follows:

Formula for Average Speed:

Average Speed = Total Distance Traveled / Time Spent

(5 + 4)/2 = 9/2

(1 - 4)/2= -3/2

The measures of angles B and C are 118° and 62°, respectively.

A system of three angles is generated by two lines intersecting each other. In accordance with Euclidean geometry, angle C is opposite to the angle with measure 62° and angle B is supplementary to the same angle.

When two angles are opposite, then both have the same measure, and when two angles are supplementary, then the sum of their measures equals 180°. Therefore, the measures of angles B and C are 118° and 62°, respectively.

The factor that provides the basis for the grading of newly diagnosed malignant tumours is degree of differentiation.

The level of differentiation impacts an individual's capacity to control their emotions, thoughts, individuality, and connections to others. The degree of any differential equation can be obtained when it is expressed as a polynomial; otherwise, the degree cannot be defined.

The mechanisms by which immature cells develop into mature cells with particular roles are described in biology. This indicates the degree to which tumour tissue resembles the healthy tissue from which it originated in the context of cancer. Compared to poorly or undifferentiated cancer cells, well-differentiated cancer cells resemble normal cells more and grow and spread more slowly. Tumour grading systems, which vary for each form of cancer, use differentiation.

The range of the set of scores is 13.

Here,

The set of scores:

7, 8, 11, 15, 17, 20

We have to find the range of the set of scores.

What is Range of set?

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.

Now,

The highest number = 20

The lowest number = 7

Hence, Range of the data set = 20 - 7 = 13

a. A model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

b. The difference in feet between car A and car B after 10 seconds is 4 feet

c. To tell which car is in the lead,

Since the distance in feet of car A from the starting line is modeled by the function f(t) = 0.25t² + 22t - 1, where t is the time in seconds since the start of the race.

Also, the distance in feet of car B from the starting line is modeled by the function g(t) = -0.1t² + 25t.

The difference in distance between car A and car B d(t) is the difference between their distance from the starting line.

So, d(t) = f(t) - g(t)

= 0.25t² + 22t - 1 - ( -0.1t² + 25t)

= 0.25t² + 22t - 1 + 0.1t² - 25t

= 0.35t² - 3t - 1

So, a model for the difference in feet between car A and car B is d(t) = = 0.35t² - 3t - 1.

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1.

To find the difference in distance after 10 seconds, we substitute t = 10 into d(t).

So, d(t) = 0.35t² - 3t - 1.

d(10) = 0.35(10)² - 3(10) - 1

= 0.35(100) - 30 - 1

= 35 - 31

= 4 feet

So, the difference in feet between car A and car B after 10 seconds is 4 feet

Since the difference in distance in feet between car A and car B  is d(t) = 0.35t² - 3t - 1

= f(t) - g(t)

Since

There are 5354 people were in the arena.

Percentage:

The term percentage is referred as a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100.

The formula for calculating the percentage is,

Percentage = (Actual value/Total value) x 100

Given,

Here we have that, 4550 men in the arena comprised 85% of the people in the arena.

Now we need to find how many people were in the arena.

Let p be the number of people in Arena.

So, based on the percentage formula,

It can be written as,

=> 85% = (4550 / p) x 100

=> 85/100 = 4550 /p

=> 0.85 = 4550/p

=> 4550/0.85 = p

=> p = 5354

Therefore, there are 5354 people were in the arena.

The null hypothesis is a typical statistical theory which suggests that no statistical relationship and significance exists in a set of given single observed variable, between two sets of observed data and measured phenomena.

Critical value is a cut-off value that is used to mark the start of a region where the test statistic, obtained in hypothesis testing, is unlikely to fall in. In hypothesis testing, the critical value is compared with the obtained test statistic to determine whether the null hypothesis has to be rejected or not.

So, when  we compared the obtained value with the critical value then after that  Reject the null hypothesis if the obtained value is more extreme than the critical value.

The coordinates of the point 3/10 of the way between A and B are (-19/15, 1/5).

Let P be the point that is 3/10 of a way from A to B. This means that it divides P in the ratio 3:10 = AP/PB = 3/10.

To find the coordinates, use the internal division formula, which is given as:

x = (mx₂ + nx₁)/(m + n)

y = (my₂ + ny₁)/(m + n)

Where,

(x₁, y₁) = A(-3, -5)

(x₂, y₂) = B(12, 4)

m = 3 and n = 10.

Substitute the values to find the x and y coordinates of point P.

y = (3×4 + 10(-5))/(3 +10)

On solving;

y = -19/15

Solve for x coordinates;

y = (3(12) + 10(-3)/(3 +10)

on solving;

y = 1/5

Therefore, the coordinates of the point 3/10 a way from A and B is (-19/15, 1/5).

The height and width are the two dimensions that are used to measure the perimeter of a rectangular frame.

Perimeter(p)=2×[height(h)+width(w)]

The given dimensions of the frame is that the height is [tex]\frac{2}{3}[/tex] the width.
