70 mph for 4 hours?
3) I drive to Bude in Cornwall from Sheffield in about 6
hours. The distance from Sheffield to Bude is 315 miles.
What is my average speed?
4) The distance from Leeds to London is 210 miles. The train
travels at an average speed of 90 mph. If I catch the 9.30 am
train in London, at what time should I expect to arrive in
Leeds?
5) How long will an athlete take to run 2000 m at an average
speed of 4 metres per second?
6) The distance between Sheffield and Land’s End is 420
miles.
a) What is the average speed of a journey from Sheffield to
Land’s End that takes 8 hours 45 minutes?
b) If Sam covered the distance at an average speed of 63
mph, how long would it take him?
Answer:
1 --- The cyclist's average speed was 18 miles per hour.
2 --- I would travel 280 miles far.
3 --- Your average speed was 52.5 miles per hour.
4 --- You should expect to arrive in Leeds at 11:50 AM.
5 --- The athlete will run 2000 m in 8 minutes and 20 seconds.
6A --- The average speed of the journey is 48 miles per hour.
6B --- It will take him 6 hours and 40 minutes.
Step-by-step explanation:
1) 90 / 5 = 18
2) 70 x 4 = 280
3) 315 / 6 = 52.5
4) 210 / 90 = 2.3333
0.333 = 0:20
9:30 + 2:20 = 11:50
5) 2000 / 4 = 500
500 / 60 = 8.3333
0.3333 = 0:20
8.3333 = 8:20
6A) 0:45 = 0.75
420 / 8.75 = 48
6B) 420 / 63 = 6.666
6.6666 = 6:40

Answer:
m < -7
Step-by-step explanation:
Maybe you want to find the value of m.
Subtract 5, then divide by -3.
-3m +5 > 26 . . . given
-3m > 21 . . . . . . subtract 5 from both sides
m < -7 . . . . . . . . divide by -3. Dividing by a negative number reverses the inequality.

Looking for right triangle side a is 1 inch long,and side b is 2 inches long. What is the length of side c?
Answer:
[tex]\sqrt{5}[/tex]
Step-by-step explanation:
[tex]a^{2} + b^{2} = c^{2}[/tex]
In this situation a = 1, b = 2
[tex]1^{2} + 2^{2} = c^{2}[/tex]
1 + 4 = [tex]c^{2}[/tex]
5 = [tex]c^{2}[/tex]
c = [tex]\sqrt{5}[/tex]
This is an important mathematical theorem to know. It's called the Pythagorean Theorem.
A curve has equation y = f(x). (a) Write an expression for the slope of the secant line through the points P(2, f(2)) and Q(x, f(x)). x − 2 f(x) − f(2) f(2) − 2 f(x) − x f(x) − x f(2) − 2 f(x) − f(2) x − 2 (b) Write an expression for the slope of the tangent line at P. lim x→0 f(x) − f(2) x − 2 lim x→2 x − 2 f(x) − f(2) lim x→2 f(x) − f(2) x − 2 lim x→0 f(x) − x f(2) − 2
Does the point (7, 4) satisfy the equation y = x − 3?
Answer:
Yes.

7=4-(-3)
Then, we do keep, change, change
7 = 4+3
Y = 7
The equation is true, so that means the points are.

20% of the applicants for a certain sales position are fluent in both Chinese and Spanish. Suppose that four jobs requiring fluency in Chinese and Spanish are open. Find the probability that two unqualified applicants are interviewed before finding the fourth qualified applicant, if the applicants are interviewed sequentially and at random.
Answer:
The probability that two unqualified applicants are interviewed before finding the fourth qualified applicant = 0.164
Step-by-step explanation:
Let,
The number of unqualified applicants are interviewed before finding the fourth qualified applicant = x
So,
X be the negative Binomial (n = 4 , P = [tex]\frac{20}{100} = 0.2[/tex] )
As , we know that
P(X = n ) = ⁿ⁺⁴⁻¹Cₙ × (1 - 0.2 )⁴ × (0.2)ⁿ for n = 0, 1, 2, ....
As we have to find the probability that two unqualified applicants are interviewed before finding the fourth qualified applicant
⇒n = 2
∴
P(X = 2 ) = ²⁺⁴⁻¹C₂ × (1 - 0.2 )⁴ × (0.2)² for n = 0, 1, 2, ....
= ⁵C₂ × (0.8 )⁴ × (0.2)²
= [tex]\frac{5!}{2! (5-2)!}[/tex] × 0.41 × 0.04
= [tex]\frac{5.4.3!}{2.1! (3)!}[/tex] × 0.0164
= [tex]\frac{5.4}{2}[/tex] × 0.0164
= 10 × 0.0164 = 0.164
∴ we get
The probability that two unqualified applicants are interviewed before finding the fourth qualified applicant = 0.164

What are regular polygons?A regular polygon is a closed shape that has straight sides of equal length and interior angles of equal measure.
This means that all of the sides and angles of a regular polygon are congruent (i.e., have the same size).
We have,
Some examples of regular polygons include equilateral triangles, squares, pentagons, hexagons, and so on.
A regular polygon can have any number of sides, and its name reflects the number of sides it has.
For example, a polygon with three sides is called a triangle, a polygon with four sides is called a quadrilateral, a polygon with five sides is called a pentagon, and so on.
Thus,
Figure C appears to have all sides and angles the same.

Answer:
h(x)≥ 5
Step-by-step explanation:
If h(x) = x+2
Range is the output value for all input variables x
If x <3
h(x) < 3 + 2
h(x) < 5
Also h(x) = -x+8, if x ≥3
h(x ) = -3 + 8
h(x)≥ 5
Combining both inequalities
h(x)≥ 5
5 ≤ h(x) < 5
Hence the required range is h(x)≥ 5

A field is a rectangle with a perimeter of 1240 feet. The length is 400 feet more than the width. Find the width and length of the rectangular field.
The width
Answer: The length is 510 and the width is 110.
Step-by-step explanation:
To find the area of a rectangle, you will have to add the 2 times the length plus 2 times the width because a rectangle have 4 sides. Two widths and two lengths.
You can now use the formula P= 2l + 2w
were P is the perimeter , l is the length, and w is the width.
the length is 400 more than the width, so we can represent that by the equation, l = w + 400
And now we know that the width is w.
So now we will input the perimeter, length, and into the formula to solve for w.
1240 = 2(w + 400) + 2w
1240 = 2w + 800 + 2w
1240 = 4w + 800
-800 -800
440 = 4w
w = 110
L= 110 + 400
L = 510
Check :
1240 = 2(510) + 2(110)
1240 = 1020 + 220
1240 = 1240
Job-sharing is an innovative employment alternative that originated in Sweden and is becoming popular in the United States (for example, in 2001, 26% of companies in the U.S. offered it as a flexible work option). Firms that offer job-sharing plans allow two or more persons to work part-time, sharing one full-time job. For example, two job-sharers might alternate work weeks, with one working while the other is off. Job-sharers never work at the same time, and may not even know each other. Job-sharing is particularly attractive to working mothers and to people who frequently lose their jobs due to fluctuations in the economy. In a recent survey of 1,035 major U.S. firms, approximately 23% offer job-sharing to their employees.
For each of the questions, select the correct answer from choices i. through xi. listed below.
a. What is the population of interest?

What is a population and parameter?The entire group or system which we are taking in consideration is population. Nothing bigger than it lies there in consideration.
Ex: If we're taking about health problem in a country, then the whole country people form a population.
If we're taking about numbers on a 6 face die, then those 6 numbers on 6 faces form a population.
Those numbers who summarize information about population are called parameter.
What is sample and statistic?A portion of population taken and analyzed to predict information about population is called sample of that population.
Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.
Those numbers who summarize information about sample are called statistic.
(Statistic is different than statistics)

William bought 5 rulers for $7.50. If r represents the cost of one ruler, which equation represents this situation?
Group of answer choices
5r = 7.50
r/5 = 7.50
r + 5 = 7.50
7.50r = 5
Answer:
5r = 7.50
Step-by-step explanation:
As, the cost of 1 ruler = r
So, r times 5 ruler will give u the cost of 5 rulers, which is 7.50
So, 5r = 7.50
