The box plots show the student grades on a chapter test compared to the grades on a retest in the same class. Box plots titled Chapter Test versus Retest with horizontal axis labeled Class Marks ranges from 0 to 100. Chapter Test box plot with minimum between 40 and 50 and maximum between 90 and 100 has interquartile ranges approximately between 50 and 80 and median approximately at 70. Retest box plot with minimum between 50 and 60 and maximum approximately at 100 has interquartile ranges approximately between 60 and 80 and median approximately between 60 and 70. Which of the following best describes the information about the medians? The chapter test and retest medians are almost the same. The chapter test and retest Q3 are the same, but the chapter test has the higher median. The chapter test median is much higher than the retest median. The low outlier on the chapter test pulls the median lower.

Answer:

59.4 km

Step-by-step explanation:

use the formula distance = velocity x time

where velocity = 4.95 km/sec

time = 12 sec

plugin values into the formula

distance = 4.95 km/sec x 12 sec

distance = 59.4 km

therefore,

thor's hammer travelled 59.4 km

Answer:

1. Statisticians and operations research analysts.

2. 167,582.3 persons.

3. 40%.

4. Pharmacist

Step-by-step explanation:

1.  According to data from the U.S. Bureau of Labor Statistics,  Statisticians and Operations Research analysts are among the fastest-growing occupations in terms of their percent growth, having high projected growth rates of 33.8 percent and 30.2 percent.

2. People who are expected to work as Mathematicians by 2026 are projected to grow up to 27.9 percent (167,582.3 persons).

3. About 40% of the fastest-growing careers are in the health & human services industry. This is the case because as the human population continues to increase, the need for healthcare providers will increase rapidly.

4. Considering the lower projection of 22% for this career,  it gives better prospects for getting employment due to the limited supply of Pharmacists.

Answer: flight to NYC

distance: 740 rate: 495+x time: 740/495+x

flight home:

distance: 740 rate: 495-x time: 740/495-x

Step-by-step explanation: the plane is flying with the wind when flying to NYC so the planes speed, or rate, can be modeled as 495+x

on the flight back home plane is flying against the wind so the planes speed, or rate, can be modeled as 495-x

Answer:

Order from least to greatest: 1/5, 0.75, 1/2, 04.

Explanation:

1/5 is the least because 0.75 is equivalent to 1/4 and 1/2 is greater than both of those. 04 is a whole number because the 0 doesn't matter if there's no decimal point, which there isn't. So take away the 0 and you get the whole number 4! Hope this helped :)

Answer:

Step-by-step explanation:

this problem focuses on the combined work rate

both can finish the work under 63 minute

let bobby mow the lawn in x minute

Billy will then mow the lawn in x-25 minutes

Let the completed job = 1 (a mowed lawn)

we can now apply the combined work formula for the two boys as

[tex]\frac{63}{x}+\frac{63}{x-25}=1[/tex]

multiplying through by x(x-25 )we have

[tex]63(x-25)+63x= x(x-25)[/tex]

open bracket we have

[tex]63x-1575+63x= x^2-25x[/tex]

rearranging and collecting like terms we have

[tex]0=x^2-25x-63x-63x+1575 \\\\0=x^2-151x+1575 \\\\x^2-151x+1575=0[/tex]

we can now use the quadractic formula

[tex]x=\frac{-b\frac{+}{} \sqrt{b^2-4ac} }{2a}[/tex]

a= 1

b= -151

c= 1575

[tex]x=\frac{-(-151)\frac{+}{} \sqrt{151^2-4*1*1575} }{2*1}[/tex]

[tex]x=\frac{-(-151)\frac{+}{} \sqrt{22801-6300} }{2} \\\\x=\frac{-(-151)\frac{+}{} \sqrt{16501} }{2} \\\\x=\frac{-(-151)\frac{+}{} 128.45}{2} \\\\[/tex]

[tex]x=\frac{-(-151)+128.45}{2} \\\\\x=\frac{279.45}{2} \\\\x=139.72 \\\\\\x=\frac{-(-151)-128.45}{2}\\\\x=\frac{151-128.45}{2}\\\\x=\frac{22.55}{2}\\\\x=11.27[/tex]

the first answer x= 139.72 approximately 140 minutes mins is correct for  Bobby's time

let us check

[tex]\frac{63}{140}+\frac{63}{140-25}=1\\\\\\0.45+\frac{63}{115} =1\\\\0.45+0.5478=1\\0.997 =1[/tex]

we can see that the solution approximates to 1

Answer: what are you talking about????????

Step-by-step explanation:

Given: triangle NOP is similar to triangle WXY

We know that NOP has a base length of 4 while triangle WXY has a base length of 10

10 / 4 = 2.5

The scale factor = 2.5

We also know that all similar triangles have congruent angles

The measure of angle X on triangle WXY = 58 degrees because its corresponding angle on triangle NOP = 58 degrees.

We know that all the angles of a triangle add up to 180.

The measure of angle P for triangle NOP is:

180 - (49 + 58) = 73 degrees. This means that the measure of angle Y for triangle WXY is also 73 degrees.

We know that the scale factor = 2.5 so 12 / 2.5 = 4.8

NP / WY = 12 / 4.8 = 2.5

The length of WX = 6 * 2.5 = 15

The length of NP = WY / 2.5 = 12 / 2.5 = 4.8

The scale factor of triangle NOP to triangle WXY is 2/5 =0.4.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, ΔNOP∼ΔWXY

NO/WX =OP/XY =NP/WY

6/WX =4/10 =NP/12

a) The scale factor is 4/10 =2/5

b) m∠X=58

c) m∠Y=

m∠N+m∠O+m∠P

=49°+58°+m∠P=180°

107°+m∠P=180°

m∠P=73°

So, m∠Y=73°

d. 6/WX =4/10 =NP/12

4/10 =NP/12

2/5=NP/12

NP=24/5

NP=4.8

So, NP/WY =4.8/12

e) WX

6/WX =4/10

60=4WX

WX=60/4

WX=15

f) NP

4/10 =NP/12

2/5=NP/12

NP=24/5

NP=4.8

Therefore, the scale factor of triangle NOP to triangle WXY is 2/5 =0.4.

Answer:

Step-by-step explanation:

The graph which represent the function f ( x ) = 4 [ x ] is graph B

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = 4 [ x ]

And , function f(x) = 4[x] represents the greatest integer function, which returns the largest integer less than or equal to x

The graph of the greatest integer function consists of horizontal segments, with jumps at the integers. Since the function is multiplied by 4 in this case, the distance between the jumps will be 1/4 of the original distance.

Hence , the graph is Option B
