A statistics teacher has 20 students in her class. Here is a graph showing the scores of the 20 students on a recent test.

A dotplot titled Graph A. A number line labeled test scores goes from 60 to 100. 64, 1; 75, 2; 80, 2; 85, 3; 87, 1; 88, 2; 90, 2; 91, 1; 92, 2; 95, 3; 96, 1; 98, 1.

The teacher selects a random sample of 5 students from the class. Here is a graph displaying the scores of the students she selected.

A dotplot titled Graph B. A number line labeled test scores goes from 85 to 97. 85, 1; 87, 1; 90, 1; 95, 1; 97, 1.

The teacher calculates the mean of this sample of 5 scores and plots it on a number line. She then repeats this process 100 times. Here are the results.

A dotplot titled Graph C. A number line labeled test scores goes from 86 to 97.

Which of the following gives the correct order of the graphs of the population distribution, distribution of a single sample, and an approximate sampling distribution, respectively?

A, B, C
A, C, B
C, B, A

Answer: Perimeter = 74

Step-by-step explanation:

Answer:

a) ∠x = 59°

c) ∠x = 79°

Step-by-step explanation:

a) ∠x = ∠EIH because they are alternate interior angles

c) ∠BEF = 41° because they are alternate interior angles

the sum of all three interior angles of a triangle = 180°

∠x = 180° - 60° - 41° = 79°

Answer:

a.x=58°[alternate angle]

b.x=55°[alternate angle]

c.x=180-101=79°[co- interior angle]

d.x=134°[alternate angle]

Answer:

19feet

Step-by-step explanation:

Given the expression for height of a man expressed as;

h = -16t² + 32t + 3

We are to find the maximum height reached by the man;

At the max height dh/dt = -32t + 32

v(t) = -32t + 32

0 = -32t + 32

32t = 32

t = 32/32

t = 1.sec

Substitute t = 1 into the expression given

h = -16(1)² + 32(1) + 3

h = -16 + 35

h = 19feet

Hence the maximum height reached by the man is 19feet

Answer:

its DDDDDDD

Step-by-step explanation:

Answer:

the object is in the air on the time interval (0.24 sec, 6.51 sec)

Step-by-step explanation:

The object is 'in the air' for all t such that h> 0.  We need to find the roots of h = -16t^2 + 108t - 25 = 0.  From the graph we see that both t values are positive.  Once we find them, we subtract the smaller t from the larger t, which results in the length of time the object is in the air.

Use the quadratic formula to find the roots of h(t).  The coefficients of t are {-16, 108, -25}, and so the discriminant b^2 - 4ac is

108² - 4(-16)(-25) = 11664 - 1600 = 10064, whose square root is 100.32.

Then the quadratic formula x = (-b ± √[b² - 4ac)/(2a) becomes

      -108 ± 100.32       108 ± 100.32

t = ---------------------- = --------------------- = 3.375 ± 3.135

             2(-16)                      32

or t = 6.51 or t = 0.24  (both times expressed in seconds).

So, again, the object is in the air on the time interval (0.24 sec, 6.51 sec)

Answer:

You save $266. The television costs $2394.

Step-by-step explanation:

10% off the original price is $266. The television is 10% off, meaning the new price is 90% of the original price. Therefore, you can subtract $2660 - $266 or multiply 90% × $2660.

Answer:

This is because the cube root of -1 gives a real number while the square root gives a complex number root value which we cannot write as an integer

Step-by-step explanation:

This is because, -1 raised to the power of 3 will give -1

However, -1 does not have any real root

Take for example, the square of -1 is 1

Hence the square root of -1 is not a real number which we can write as integer but a complex number which is not real

Answer:

$4,555

Step-by-step explanation:

According to the scenario, calculation of the given data are as follows,

Total deposit (P) = $2,500

Annual interest (r) = 12%

Time period (t) = 5 years

We can calculate the balance after 5 years if compounded continuously by using following formula,

FV = P[tex]e^{rt}[/tex]

By putting the value, we get

FV = $2,500 × [tex]e^{(0.12 * 5)}[/tex]

= $2,500 ×[tex]e^{.60}[/tex]

= $2,500 × 1.822

= $4,555

Answer:

Step-by-step explanation:

Answer:

Yes, the statement "An exponential decay function represents a quantity that has a decreasing halving time" is true. In addition, this process can be expressed by the following differential equation, where N is the quantity and λ (lambda) is a positive rate called the exponential decay constant: d N d t = − λ N . {displaystyle {frac {dN} {dt}}=-lambda N.}

I think the answer is C. x^2

Answer:

y = 10x

(x is a set of odd numbers between 11 and 99)

Step-by-step explanation:

Given;

divisor = 20

remainder, = 10

let the 3 - digits dividend = y

let the quotient = x

Arranging all in mixed fraction;

[tex]\frac{y}{20} = x\frac{10}{20} \\\\\frac{y}{20} = \frac{10x}{20} \\\\\frac{y}{20} = \frac{x}{2} \\\\2y = 20x\\\\y = 10x[/tex]

where x = 11, 13, 15, 17, 19 - - - - - - - 99

The divisor would be between 5 and 49. So I chose 38. 38x20 is 760. 760+ 10 (which is the remainder) is 770.

Therefore, The divisor would be 38 and the dividend would be 770.

Have a great day!
