The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
Answer:
Center Z score = 4.5
The score is unusual
Step-by-step explanation:
The mean height of a basketball team is 6 feet with the standard deviation of 0.2 feet. The team center is 6.9 feet tall. Find the center Z score. Is the score unusual?
The formula for z score is:
z = (x-μ)/σ, where
x is the raw score = 6.9feet
μ is the population mean = 6feet
σ is the population standard deviation = 0.2 feet
Hence:
Z = 6.9 - 6/0.2
Z = 0.9/0.2
Z = 4.5
Yes this score is unusual

The answer to this problem is:
X= -1 Y=1
Solve for the variable
Answer:
40
Step-by-step explanation:
Try to get the variable alone by dividing 5/8 on both sides of the equations.
That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.
Answer:
40
Step-by-step explanation:
Multiply both sides by 8/5

Step-by-step explanation:
Mark should have rounded 271 to 250 and rounded 582 to 550: 250 + 550 = 800.
B.
00:00
Mark should have rounded 271 to 250 and rounded 582 to 600: 250 + 600 = 850.
C.
00:00
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Answer:
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Step-by-step explanation:
Rounding to the nearest hundred means rounding 271 to 300 and 550 to 600.
Think of it as
271 changes to 0.271
The 7 would be in the hundredths place.
7 is greater than 5; therefore, round up.
Now you have 0.3, change this back to it's normal decimal places to get 300.
550 changes to 0.550
Where the second 5 would be in the hundredths place.
5 is equal to 5; therefore, round up.
Now you have 0.6, change this back to it's normal decimal places to get 600.
Mark rounded to the nearest place which is not the same.

x + y = 10
y = ?
Answer:
x+y=10
y=10-x
To isolate y, you subtract x on both sides.

What value is equivalent to (5-3•2^3) + 9-4^2? PLS HURRYYY
Answer:
-26 is your answer
Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.
Hope this helped you!!!!
Help ur gurl out.
Lol
Explanation:
4²+4²≠8²
(4+4)²=8²
If you use PEMDAS you can find that 4²+4²=32 not 8² which equals 64
You can also find that (4+4)²=(8)²
4x + y = 7 and passes through the point (1, 8)?

covert this repeating decimal into a fraction
Answer: 4311/9900 or 479/1100
Step-by-step explanation:
Okie so in order to do this, we need to get rid of the repeating part of the decimal
==============================================================
Right now we have x = 0.435454545454...
If we multiply this by 100, we get
100x = 43.545454545454
And if we multiply by 10000 we get
10000x = 4354.5454545454
==============================================================
Subtract the two equations
10000x = 4354.5454545454
100x = 43.545454545454
------------------------------------------------- (notice: the repeating part will cancel out)
9900x = 4311
x = 4311/9900
If you simplify the fraction you get: 479/1100
The fraction that represents the repeating decimal is
[tex]\frac{479}{1100}[/tex]
Given :
A repeating decimal [tex]0.4354545454...............[/tex]
there is bar at 54 , so 54 is repeating
We need to convert this decimal into fraction
54 is repeating so we multiply by 100
Let x= [tex]0.4354545454...............\\[/tex]
[tex]100x=43.54545454...............[/tex]
Now we subtract x from 100x
[tex]100x=43.54545454...............\\ x= 0.4354545454...............\\-----------------------------------------\\ 99x=43.11[/tex]
Now divide both side by 99
[tex]x=\frac{43.11}{99} \\[/tex]
multiply top and bottom by 100 to remove the decimal
[tex]x=\frac{4311}{9900} \\Divide \; top \; and \; bottom \; by 9\\x=\frac{479}{1100}[/tex]

Write two division equations for each multiplication equation. 15⋅25=6 15 ⋅ 2 5 = 6 6⋅43=8 6 ⋅ 4 3 = 8 16⋅78=14
Answer:
[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]
[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]
[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]
Step-by-step explanation:
Given
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Required
Write 2 division equations
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
Express 15 as 15/1
[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]
Multiply numerator and denominator
[tex]\frac{30}{5} = 6[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 2)
So, we have:
[tex]\frac{30*2}{5*2} = 6[/tex]
[tex]\frac{60}{10} = 6[/tex] ---- (2)
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
Express 6 as 6/1
[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]
Multiply numerator and denominator
[tex]\frac{24}{3} = 8[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 4)
So, we have:
[tex]\frac{24*4}{3*4} = 8[/tex]
[tex]\frac{96}{12} = 8[/tex] ---- (2)
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Express 16 as 16/1
[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]
Multiply
[tex]\frac{112}{8} = 14[/tex] ---- This is (1)
Divide the fraction by a common term (e.g. 4)
[tex]\frac{112/4}{8/4} = 14[/tex]
[tex]\frac{28}{2} = 14[/tex]
if 1/4x +2y= 11/4
and - 6y - x = 7, what is
half of y?
Answer:
y/2 = 4.5
Step-by-step explanation:
1/4x + 2y = 11/4
distribute by 4 to eliminate fractions
x + 8y = 11
+ -x - 6y = 7
2y = 18
y = 9
half of 9 = 4 1/2
solve for x: tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) =sinø.(sin180-ø)
Answer:
Below.
Step-by-step explanation:
tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) = sinø(sin180-ø)
xcos(90+ø).(cos90-ø) = sinø(sin180-ø) - tan(180-ø).tan(90+ø)
x = (sinø(sin180-ø) - tan(180-ø).tan(90+ø)) / cos(90+ø).(cos90-ø)
x = - (sin^2ø + tanø(tan(90+ø)) / cos^2ø

- Drake and troy are building models. For every 10 pieces
Drake puts together, Troy puts together 6 pieces. If Troy
puts together 18 pieces, how many pieces does Drake
put together?
Answer:
30
Step-by-step explanation:
Looking at the question we will notice that every 6 that Troy puts together Drake makes 10 so its simple, Troy makes 18 so we divide that by 6 meaning we get 3. We then get 3 and multiply it by 10, Thus 30 shall be our answer.

Answer:
1 = 3
2 = 6
3 = 9
Step-by-step explanation:
for every # it is multiplied by 3 (ex. 7 • 3 = 21, 8 • 3 = 24, ect.)
therefore if it is multiplied by 3 each time
then 1 • 3 = 3
2 • 3 = 6
and 3 • 3 = 9

What is the area, in square meters, of the shaded region in the diagram?
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
