a teacher gives a 10-point to a class of 10 children.
a. is it possible for 9 of the 10 to score above average on the test? if so, give an example to show how. if not, explain why not.
b. is it possible for all 10 of the children to score above average on the test? if so, give example to show how. if not, explain why not.
Please help!!
Given what we know, we can say that it is possible for 9 out of 10 students to score above average, but it is not possible for all 10 to score above average.
How do we calculate an average score?In order to calculate the average score of the students, we must use addition.
We have to add all of the scores, in this case, 10 scores, and then divide by the number of scores.
One example of 9 out of 10 students scoring above average would be:
[tex]1 + 9 +9+9+9+9+9+9+9+9 = 82[/tex]
[tex]82/10 scores = 8.2[/tex]
This would leave us with an average score of 8.2 and 9 out of 10 students that have scored higher.
Given the way in which we calculate average scores, it is impossible for all 10 students to score above average since even if all 10 students get a perfect score, that would then become the average.

The actual length of a table is 45 1/2 inches. Harriet estimates the length of the table and finds her percent to be less than 4% What range of values represents Hamel's estimated length Enter your answers as decimals or mixed numbers in simplest form by filling in the boxes Harriet's estimated length is between inches and inches
Answer:
43.68 in and 47.32 inStep-by-step explanation:
The actual length is 45 1/2 and the estimate is within 4% of error range.
The lower range is:
45 1/2 - 4% = 91/2 - 4% = 91/2*96/100 = 91*48/100 = 43.68The higher range is:
45 1/2 + 4% = 91/2 + 4% = 91/2*104/100 = 91*47/100 =47.32So the range is between:
43.68 in and 47.32 insolve 4(x+5)=12 step by step
Answer:
x = -2
Step-by-step explanation:
you need to use the distribution property first!
4(x + 5) = 12 ------> 4x + 20 = 12
now you need to subtract 20 from both sides so that you can isolate x
4x = -8
finally, divide -8 by four so that x is alone, meaning solve to find x!
x = -2
Hey there!
4(x + 5) = 12
4(x) + 4(5) = 12
4x + 20 = 12
SUBTRACT 20 to BOTH SIDES
4x + 20 - 20 = 12 - 20
CANCEL out: 20 - 20 because it gives you 1
KEEP: 12 - 20 because it help solve for the x-value
NEW EQUATION: 4x = 12 - 20
SIMPLIFY IT!
4x = -8
DIVIDE 4 to BOTH SIDES
4x/4 = -8/4
CANCEL out: 4/4 because it gives you 1
KEEP: -8/4 because it gives the x-value
NEW EQUATION: x = -2
Therefore, your answer is s x = -2

Answer:
2x+y=6
Step-by-step explanation:
The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope-intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept.
The answer is 2x+y=6. Hope this helps :)
What fraction should be added with -4/9 to get 6/17 ?
(A) 104/163 (B) 136/151 (C) 122/153
Answer:
(C) 122/153
Step-by-step explanation:
Let x be the required fraction.
(-4/9) + x = 6/17
Add both sides by 4/9
x = (6/17) + (4/9)
= (54 + 68)/153
= 122/153
Answer:
x = 122/153Step-by-step explanation:
Let's create an equation to solve for the variable x. Then, isolate the x by adding 4/9 to both sides. Lastly, simplify and solve for the x variable.
-4/9 + x = 6/17=> 4/9 - 4/9 + x = 6/17 + 4/9=> x = 6/17 + 4/9=> x = 6(9)/17(9) + 4(17)/9(17)=> x = 54/153 + 68/153=> x = 122/153Looking at all the options, Option C is matching with our result.
Hence, Option C is correct.

A triangle has a 60° angle, and the two adjacent sides are 12 and "12 times the square root of 3". Find the radius of a circle with the same vertex as a center, if the arc in the triangle bisects the area of the triangle.
The radius of a circle with the same vertex as a center is 12 units
Application of Pythagoras theorem;To get the radius of the circle, we need to determine the diameter of the circle first:
According to SOH CAH TOA:
[tex]sin\theta = \frac{opp}{hyp} \\sin60 = \frac{12\sqrt{3}}{hyp} \\hyp =\frac{12\sqrt{3}}{sin60} \\hyp =\frac{2\times12\sqrt{3}}{\sqrt3}} \\hyp = 24 = diameter[/tex]
Determine the radius of the circle
Radius = dismeter/2
Radius = 24/2
Radius = 12
Hence the radius of a circle with the same vertex as a center is 12 units

write the number 66,190,000 using the number word "million" and then round to one decimal place
Answer:
66,190,000 = 66.19 million
round to 66.2 million
Step-by-step explanation:
The first four terms of an arithmetic sequence are: a, a + d, a + 2d, a + 3d. The first
four terms of another sequence are: A, Ar, Ar2, Ar3, where r 6= 1. The eight terms
satisfy:
a + A = 27 (1)
(a + d) + (Ar) = 27 (2)
(a + 2d) + (Ar2) = 39 (3)
(a + 3d) + (Ar3) = 87 (4)
By using the substitution a = 27 − A, or otherwise, find the all eight terms
The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509.
Determination of a given set of successive values of a sequence
By (1) we have that [tex]a = 27 - A[/tex], and we simplify the system of equations as follows:
[tex](27-A)+d + A\cdot r = 27[/tex]
[tex]d + (r-1)\cdot A = 0[/tex] (2b)
[tex](27-A) +2\cdot d + A\cdot r^{2} = 39[/tex]
[tex]2\cdot d + (r^{2}-1)\cdot A = 12[/tex] (3b)
[tex](27-A) +3\cdot d + A\cdot r^{3} = 87[/tex]
[tex]3\cdot d + (r^{3}-1)\cdot A = 60[/tex] (4b)
By (2b), we simplify the system of equations once again:
[tex]2\cdot (1-r)\cdot A+(r^{2}-1)\cdot A = 12[/tex]
[tex][2\cdot (1-r)+(r^{2}-1)]\cdot A = 12[/tex] (3c)
[tex]3\cdot (1-r)\cdot A + (r^{3}-1)\cdot A = 60[/tex]
[tex][3\cdot (1-r) + (r^{3}-1)]\cdot A = 60[/tex] (4c)
And by equalising (3c) and (4c) we have an expression in terms of [tex]r[/tex]:
[tex]\frac{12}{[2\cdot (1-r)+(r^{2}-1)]} = \frac{60}{[3\cdot (1-r)+(r^{3}-1)]}[/tex]
[tex]12\cdot [3\cdot (1-r)+(r^{3}-1)] = 60\cdot [2\cdot (1-r) + (r^{2}-1)][/tex]
[tex]36\cdot (1-r) +12\cdot (r^{3}-1) = 120\cdot (1-r)+60\cdot (r^{2}-1)[/tex]
[tex]84\cdot (1-r) +60\cdot (r^{2}-1)-12\cdot (r^{3}-1) = 0[/tex]
[tex]84-84\cdot r +60\cdot r^{2}-60-12\cdot r^{3}-12 = 0[/tex]
[tex]-12\cdot r^{3}+60\cdot r^{2}-84\cdot r +2 = 0[/tex] (5)
The roots of this third order polynomial are: [tex]r_{1} \approx 0.0242[/tex], [tex]r_{2} = 2.488 + i\,0.831[/tex] and [tex]r_{3} \approx 2.488-i\,0.831[/tex]. Since [tex]r[/tex] must be a real number, then [tex]r \approx 0.0242[/tex].
By (4c) we have the value of [tex]A[/tex]:
[tex]A = \frac{60}{3\cdot (1-0.0242)+(0.0242^{3}-1)}[/tex]
[tex]A \approx 31.130[/tex]
By (2b) we find the value of [tex]d[/tex]:
[tex]d = (1-0.0242)\cdot 31.130[/tex]
[tex]d = 30.377[/tex]
And by (1) we find the value of [tex]a[/tex]:
[tex]a = 27-A[/tex]
[tex]a = 27-31.130[/tex]
[tex]a = -4.13[/tex]
The first eight terms are calculated below:
[tex]n_{1} = 27[/tex]
[tex]n_{2} = 27[/tex]
[tex]n_{3} = 39[/tex]
[tex]n_{4} = 87[/tex]
[tex]n_{5} = [-4.13 + 4\cdot (30.377)]+(31.130)\cdot (0.0242)^{4} = 117.378[/tex]
[tex]n_{6} = [-4.13+5\cdot (30.377)+(31.130)\cdot (0.0242)^{5}] = 147.755[/tex]
[tex]n_{7} = [-4.13+6\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{6}] = 178.132[/tex]
[tex]n_{8} = [-4.13+7\cdot (30.377)\cdot (31.130)\cdot (0.0242)^{7}] = 208.509[/tex]
The first eight terms of the sequence are 27, 27, 39, 87, 117.378, 147.755, 178.132 and 208.509. [tex]\blacksquare[/tex]
