A group of teachers decided that they would each bring a similar jar of candies to their classrooms so their
students could practice estimation. The students were told that whoever had the closest guess in the class
would win the candy, and so they all guessed how many candies were in their classroom's jar. The
distribution of individual guesses was strongly skewed to the right with a mean of 115 candies and a
standard deviation of 35 candies.
Suppose we took random samples of 6 students and calculated T as the sample mean of their guesses. We
can assume that the students in each sample are independent.
What will be the shape of the sampling distribution of ?

Answer:

A

Step-by-step explanation:

300-50-70+20

Answer:

I believe it would be answer A.

Step-by-step explanation:

When depositing, you're make an addition. Withdrawing, is removing. Making these checks had removed about 120 dollars out of his bank account, meaning the equation would be 300-50-70+20.

Hope this helps! :D

Answer:

c- use 1.0 as an estimate

Step-by-step explanation:

Answer:

x < 0

Explanation:

A negative times a negative equals a positive, and the expression is positive, so x has to be negative/less than 0

I know you already got the answer, but one of the links was deleted so I thought I'd post it as an answer instead of a comment :)

Answer:

  6π ≈ 18.8 miles

Step-by-step explanation:

The full circumference of a 12-mile circle is ...

  C = πd

  C = π(12 mi)

So, half the circumference of the circle is ...

  arc length = 1/2C = (12π mi)/2 = 6π mi ≈ 18.8 mi

Answer:

D. (12 x 10) + (5 x 4)

Step-by-step explanation:

If you draw a line separating the big square from the little square,  you have a 12 x 10 large square, and a 5 x 4 smaller square. We know the second dimension of the small square because the large square takes 10ft off of the total length of 4ft.

Calculate both areas separately, then add them together.

Answer:

i. A = $25 t + $150

ii. B = $35 t + $100

iii. Number of hours = 5

Step-by-step explanation:

For company A:

A = $25 t + $150

where A is the amount charged and t is the number of hours of landscaping.

For company B:

B = $35 t + $100

where B is the amount charged and t is the number of hours of landscaping.

When the time  is 5 hours, then:

i. A = $25 t + $150

     = $25 (5) + $150

     = $125 + $150

A = $275

ii. B = $35 t + $100

      = $35(5) + $100

      = $175 + $100

B = $275

Therefore, the number of hours that would make the cost of each company to be the same is 5 hours.

$15,840

Step-by-step explanation:

10% of 17600 = 1760

17600 - 1760 = 15840

Answer:

y  =  2 -  ( x - 1)²/9

Step-by-step explanation: See Annex

As the parameter t increases,  the value of x increases and the value of y decreases, we get the figure of the annex ( the arrow in the Annex indicates the way of the curve with t increasing.

b) to eliminate the parameter:

x  =  1  + 3*t    (1)          y  =  2  -  t²  (2)

Then  from equation (1)  t  = ( x  - 1 ) / 3

plugging that value in equation (2)

y  =  2  -  [ (  x  -  1 ) / 3 ]²

y  =  2  - ( x² + 1 - 2*x)/9

9*y  =  18  - x² + 1 - 2*x    or    y  =  2 -  ( x - 1)²/9

The curve is a parabol

Answer:

[tex]y' = (6,4)[/tex]

Step-by-step explanation:

Given

[tex]y = (3,2)[/tex]

[tex]x = (4,0)[/tex]

[tex]z = (2,-2)[/tex]

[tex]D_{(O,2)}[/tex]

Required

The image of y

[tex]D_{(O,2)}[/tex] implies that y is dilated by a scale factor of 2 across the origin.

So, the image of y is:

[tex]y' = 2 * y[/tex]

[tex]y' = 2 * (3,2)[/tex]

[tex]y' = (6,4)[/tex]

Answer:

The first three terms are: 25, 125 and 625

Step-by-step explanation:

Given

[tex]a =25; r = 5[/tex]

Required

The first three terms

The nth term of a geometry progression is:

[tex]T_n =ar^{n-1[/tex]

So, we have:

First term: [tex]n = 1[/tex]

[tex]T_n =ar^{n-1[/tex]

[tex]T_1 =25 * 5^{1-1[/tex]

[tex]T_1 =25 * 5^0[/tex]

[tex]T_1 =25 * 1[/tex]

[tex]T_1 =25[/tex]

Second term: [tex]n = 2[/tex]

[tex]T_n =ar^{n-1[/tex]

[tex]T_2 =25 * 5^{2-1[/tex]

[tex]T_2 =25 * 5^{1[/tex]

[tex]T_2 =25 * 5[/tex]

[tex]T_2 =125[/tex]

Third term: [tex]n = 3[/tex]

[tex]T_n =ar^{n-1[/tex]

[tex]T_3 =25 * 5^{3-1[/tex]

[tex]T_3 =25 * 5^{2[/tex]

[tex]T_3 =25 * 25[/tex]

[tex]T_3 =625[/tex]

The answer is J. When the circle on the graph is filled in, that means that number is included in the solution.

25x </= 300

Divide both sides by 25

x </= 12

Step-by-step explanation:

Answer:

1. Obtuse angle

2. 5

3. 117

Step-by-step explanation:

1. Any angle that is wider than 90 degrees is obtuse.

2. 180 = straight angle so, 180-140=40 8x5=40 so x=5

3. Supplementary angles are one angle that is 180 so, 180-63= 117

Answer:

a) The value of q is 0.2.

b) E(X) = 1.85.

Step-by-step explanation:

Question a:

The sum of all the probabilities must be 1. So

[tex]0.3 + x + 0.1 + 0.15 + 0.25 = 1[/tex]

[tex]x + 0.8 = 1[/tex]

[tex]x = 0.2[/tex]

The value of q is 0.2.

Question b:

Multiplication of each value of x by its probability. So

[tex]E(X) = 0*0.3 + 1*0.2 + 2*0.1 + 3*0.15 + 4*0.25 = 1.85[/tex]

So the answer is E(X) = 1.85.

Answer:

C. A = 0.5*d1*d2

D. A = bh

Step-by-step explanation:

The area of the rhombus can be found depending on what information is made available to us.

If given the lengths of the two diagonals (d1 and d2) of a rhombus which bisect each other, therefore, the formula for finding the area would be:

A = 0.5*d1*d2

Also, if we are given the height (h) and side (b), the formula to use would be:

A = bh

Answer:

The system of equations has one solution. The two equations are intersecting lines.

Step-by-step explanation:

if you want to use the substitution method, you would have to plug in y for 12x+2 in the second equation.

2(12x+2)=x+4

next, you have to distribute

24x+4=x+4

subtract 24x from each side

4=-23x+4

subtract 4 from each side

0=23x

divide each side by 23

x=0

now, plug in 0 to one equation.

y=12(0)+2

y=2

the lines intersect at one point, (0,2)
