The length of a rectangle is 5 less than twice the width, and the area of the rectangle is 52 ft^2. Find the dimensions of the rectangle.

Answer:

KL = 28

YZ = 76

LZ = 38

Step-by-step explanation:

Because J K and L are midpoints, the segment lengths are half of the segments from the XYZ triangle.

Think of it like this: ZLK is just ZXY scaled to half.

From that we get:

KL = YX/2 = 56/2 = 28

YZ = 2*KJ = 2*38 = 76

LZ = YZ/2 = 76/2 = 38

Answer: KL= 28

Explanation: YJ and JK are 28 each and together they add up to 56. Since KL has the same measure as YJ, its measure is 28.

Answer: YZ= 76

Explanation: JK is half the measure of ZY, so if you multiply 38 by 2 you get 76.

Answer: LZ= 38

Explanation: LZ=JK, so LZ=38

Answer:

A) Airplane A has a lesser median

Step-by-step explanation:

If you look at the photo you see both airplane A and airplane B and if you were to line them up

airplane A=3

airplane B=4 ½  

so clearly airplane A would have a lesser median than airplane B

Answer: [tex](12,-3)\ \text{or}\ (3,-12)[/tex]

Step-by-step explanation:

Given

The product of integers is -36

The difference of integers is 15

Suppose the integers are x and y

[tex]\Rightarrow x-y=15\\\Rightarrow x=15+y\\\Rightarrow xy=-36[/tex]

Put the value of [tex]x[/tex] in the product

[tex]\Rightarrow (15+y)y=-36\\\Rightarrow 15y+y^2+36=0\\\Rightarrow y^2+12y+3y+36=0\\\Rightarrow y(y+12)+3(y+12)=0\\\Rightarrow (y+12)(y+3)=0\\\Rightarrow y=-3\ \text{or}\ -12[/tex]

[tex]\therefore x=12\ \text{or}\ 3[/tex]

Pairs of integers are [tex](12,-3)\ \text{or}\ (3,-12)[/tex]

Answer:

20 students offered both physics and biology.

Step-by-step explanation:

n(Total) = 50

n(Physics) = 40

n(Biology) = 30

Let n(Physics and Biology) = x

n(Physics only) = 40 -x

n(Biology only) = 30 - x

40 - x + 30 - x + x = 50

70 - x = 50

x = 20

Step-by-step explanation:

Green vines attached to the trunk of the tree had wound themselves toward the top of the canopy. Ants used the vine as their private highway, avoiding all the creases and crags of the bark, to freely move at top speed from top to bottom or bottom to top depending on their current chore. At least this was the way it was supposed to be. Something had damaged the vine overnight halfway up the tree leaving a gap in the once pristine ant highway.

The whole numbers will be:

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

Remember that a square root will have a whole number as an outcome only if the input is a square number.

Then, what we can do here is just find all the square numbers smaller than 200.

1*1 = 1

2*2 = 4

3*3 = 9

4*4 = 16

5*5 = 25

6*6 = 36

7*7 = 49

8*8 = 64

9*9 = 81

10*10 = 100

11*11 = 121

12*12 = 144

13*13 = 169

14*14 = 196

Then, if we take the square roots of all the natural numbers from 1 to 200, we will have 14 whole numbers as outcomes, and these will be:

{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14}

Answer:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

Step-by-step explanation:

A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.

Time is the number of hours, so it is mean, and not proportion.

Variable of interest is time to complete the round, and since it is measured in hours it is a quantitative variable.

The answer is:

The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.

The confidence interval for a population of variable of interest time is normally distributed  . The Confidence interval for proportion mean should be constructed because the  variable of interest is the time taken to complete one round of golf score, time to complete the round.

Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables  of  the sample taken which is a  quantitative variable.

The confidence interval for the normally distributed variable of interest is determined by the equation as formulated below

[tex]\rm Confidence\; Interval = \mu - Z \sigma/\sqrt{n} \;\;to \; \mu + Z \sigma/\sqrt{n} \\Where\\\mu = Sample\; mean \\Z = Z \; score \\\\\sigma = Sample\; standard \; deviation \\n = Sample \; size[/tex]

We have to  indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest.

A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.

The goal of the research was to estimate the amount of time  it typically takes to complete a round of golf on Saturday morning

As given by the language of the question we can conclude that the variable of interest is the time taken to complete one round of golf.

So we consider that the time variable is normally distributed

Also time variable is quantitative variable.

So we can fill in the blanks

The confidence interval for a population of variable of interest time is normally distributed .The Confidence interval for  proportion mean should be constructed because the  variable of interest is the time taken to complete one round of golf score, time to complete the round.

Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables  of  the sample taken which is a  quantitative variable.
