Nathan And Jordan Design Surveys To Determine The Average Amount Of Time Bicyclists In A Race Spend Training

Answers

Answer 1

Answer: A) Nathan’s because his sample was more random

Step-by-step explanation: sampling methods quiz on edge

Answer 2

Nathan's sample is likely to be the most valid. Nathan's because his sample contained elements of the population.

What is a Survey?

In order to gather information on a service, product, or process, a survey is described as an act of looking at a process or asking a predetermined sample of people. Surveys used to gather data ask a specific set of individuals about their beliefs, actions, or knowledge.

Given, To find out how much time cyclists are in a race train on average each week, Nathan and Jordan develop questionnaires. Every fifth cyclist who crosses the finish line after a race is surveyed by Nathan. Jordan takes a survey of the top five cyclists who cross the finish line.

Since Nathan's sample contained elements of the population.

and it is more random.

The sample used by Nathan is probably the most reliable. Nathan's because the population was represented in his sample.

The longer leg of the right triangle is 8 more than the shorter leg. The hypotonuse is 8 more than the longer leg. FInd all 3 sides

Answers

Answer:

4[tex]\sqrt{13}[/tex]

4[tex]\sqrt{13}[/tex] + 8

4[tex]\sqrt{13}[/tex] + 16

Step-by-step explanation:

as per the given information:

shorter leg = x

longer leg = x + 8

hypotonuse = x + 8 + 8

remember the Pythagorean theorem, which states

x^2 + y^2 = n^2

where x and y are the legs and n is the hypotenuse

so now one can set up an equation:

x^2 + ( x + 8 )^2 = ( x + 16 ) ^2

simplify and solve using inverse operations:

first preform the square

x^2 + x^2 + 16x + 64 = x^2 + 32x + 256

then preform inverse opertations and simplify

2x^2 + 16x + 64 = x^2 + 32x + 256

-x^2                       -x^2

x^2 + 16x + 64 = 32x + 256

       -16x            -16x

x^2 + 64 = 16x + 256

       - 64             -64

x^2 = 16x + 192

-16x     -16x

x^2 - 16 = 192

x^2 -4^2 = 192

remember the differnt ways of writing a special square

(x - 4) (x + 4) = 192

x = 4[tex]\sqrt{13}[/tex]

now add 8 to find the longer leg

4[tex]\sqrt{13}[/tex] + 8

an add another 8 to find the hypotenuse

4[tex]\sqrt{13}[/tex] + 8 + 8

4[tex]\sqrt{13}[/tex] + 16

Communities A,B and C are faced with acute water problem. The distance between communities A and B is 5km and that of A and C 7km. The angle between path AB and AC is 45degrees. If a well is dug for the three communities such that it would have equal distance to the path linking each communities. (a) Indicate by a way of sketching the exact place to dig the well? (b) Measure the distance between communities B and C?

Answers

Answer:

a) by finding the incentre

b) 5 km

Step-by-step explanation:

Let the communities A, B and C be shown by the three points of the triangle as shown in the figure below. As the angle between the path Ab and Ac is 45 degrees this is an isosceles triangle having two angles equal. As this is an isosceles triangle it must also have two sides equal .

a) the in center   point can be used to  have equal distance to the path linking each communities.

We take a compass and draw arcs on the two sides of the vertex and placing the compass on the arcs bisect each angle made by the triangles arms.

Joining the bisectors the lines meet at a point which is highlighted by a circle in the diagram.

This is the incentre which is equidistant from each vertex.

b) Using Pythagorus theorem

c² = a² + b²

7²= 5² + b²

b²= 24

b= 4.89= 5 km

The path between B and C is also 5 km.

Which situation requires the use of the cube root?
A. Determine the surface area of a cube given the side
B. Determine the volume of a cube given the side
C. Determine the side of the cube given the volume
D. Determine the volume of a sphere given the radius

Answers

Answer:

C

Step-by-step explanation:

Mathematically, the volume of a cube of side L is given as;

V = L^3

Now, given V and we want to find L, what we shall simply do is to find the cube root of both sides

By finding the cube roots of both sides, we can easily get the value of the side of the cube in question

Which statement about the ordered pairs (3, -8) and (4, 4) is true for the equation 3x - y/4 = 11?

A. Neither ordered pair is a solution.

B. Both ordered pairs are solutions.

C. (4, 4) is a solution to the equation but not (3, -8).

D. (3, -8) is a solution to the equation but not (4, 4). ​

Answers

Answer:

Neither ordered pair is a solution.

Step-by-step explanation:

If we substitute an ordered pair which is the correct solution, we will obtain the value at the right hand side of the equation.

Now let us try it;

Substitute (3,-8)

3(3)-(-8)/4 = 9 +8/4 =17/4

Again;

3(4) - 4/4 = 8/4 =2

Hence, none of the ordered pairs is a solution.

-7 squared is -49, -49 plus 49 is 0.

(-7)^2=49 and 7^2=49

Kenny had a total of 140 minutes to read, do homework, and play video games. he spent x minutes reading. he spent 2(x + 5) minutes doing homework and he spent 25 minutes playing video games. How many minutes did Kenny spent reading?

Answers

Answer:

35 min

Step-by-step explanation:

given that the total time spent is 140min

and that the time spent reading is x minutes

and also that the time spent doing home work is 2(x+5)

the time spent playing video game is 25

the expression for the total time is given as

total = reading +homework +video game

140=x+2(x+5)+25

solving for x we have

140=x+2x+10+25

140=3x+35

140-35=3x

105=3x

x=105/3

x=35

kenny spent 35 min reading

Time spend for reading is 35 minutes

Given that;

Total number of minutes Kenny have = 140 minutes

Time spend for reading = x

Time spend for homework = 2(x + 5) = 2x + 10

Time spend for games = 25 minutes

Find:

Time spend for reading

Computation:

Total number of minutes Kenny have = Time spend for reading + Time spend for homework + Time spend for games

140 = x + 2x + 10 + 25

3x + 35 = 140

3x = 105

x = 105 / 3

x = 35

So,

Time spend for reading = 35 minutes

Steve and Brian are both avid bicyclists. Each week, Steve rides for a total of 2x hours at an average speed of x miles per hour.
sBrian rides 6 more hours a week than Steve, but at an average speed that is 4 miles per hour less than Steve's average speed.
Which of the following functions will give the total distance that Brian rides each week, in miles?

Answers

Answer:

m(x) = 2x^2 - 2x - 24

Step-by-step explanation:

We will use the speed formula for this.

d/t = s

d is distance

t is time

s is speed

since we are looking for a function that gives the distance, we must rewrite

the equation to have d on one side of the equation by itself. We will do this by multiplying both sides by t.

(d/t)t = (s)t

which simplifies to:

d = st

Now we must find out what s and t are.

t: Steve's time riding is 2x hours, and Brian's is 6 more hours, so

Brian's time riding is 2x + 6.

so t = 2x + 6.

s: Steve's speed is x mph. Brian's is 4 less than that so

s = x - 4.

Now we can plug in what we know the the formula we made: d=st

d = (2x + 6)(x-4)

now we can FOIL.

(2x)(x)= 2x^2

(2x)(-4)= -8x

(6)(x) = 6x

(6)(-4) = -24

d = 2x^2 - 8x + 6x - 24

simplify:

Answer: d = 2x^2 -2x - 24

Which value of x satisfies the equation |-2x|=10

Answers

Answer:

Step-by-step explanation:

First you will divide I-2xI on both sides that should look like this:

       -2x/-2 = 10/-2

when you divide it your -2‘s should cancel out and you should be left with

         -x=10/-2

when You divide 10/-2 you should get -5

         10/-2= -5

your answer should look like this then

         -x=-5

-5 is just one of your answers the other is 5

To get rid of the negative on the -X you have to didvide it by both sides

        -x/-x=-5/-x

your answer should be

          X= 5

your final answers are

      -5 or 5

The value of x is "5".

Equation:

[tex]|-2x|=10[/tex]

x=?

[tex]\to |-2x|=10\\\\\to 2x=10\\\\\to x=\frac{10}{2}\\\\\to x= 5[/tex]
