2. WHICH ONE DOESN'T BELONG? Which circle does not belong with the other three? Explain your reasoning ( 6 in. 12 in. 1 ft 6 in.
The first circle doesn't belong to the other three as it has a radius in it whereas the other circles have a diameter.
Circle 4 is different from other other Circles.
What is radius and Diameter of Circle?The radius of a circle is the distance from the center of the circle to any point on its circumference. The diameter of a circle is a line segment that passes through the center of the circle and has its endpoints on the circumference.
1. In Circle 1, the radius is 6 inch
So, Diameter= 6 x 2= 12 inch
2. In Circle 2, the diameter is 1 feet
Diameter = 1 feet = 12 inch
3. In Circle 3, the diameter is 12 inch
4. In Circle 4, the diameter is 6 inch.
Since, Circle 1, 2 and 3 have the diameter 12 inch but the Circle 4 have the diameter 6 ich.
Thus, Circle 4 is different from other other Circles.

Suppose that 80%, percent of trees in a forest of 300 trees are infected with a virus, and we take an SRS of 5 trees to test for the virus. What is the probability that exactly 2 of the 5 trees have the virus? You may round your answer to the nearest hundredth. P(X=2)=P(X=2)=P, left parenthesis, X, equals, 2, right parenthesis, equals
Answer:
0.05
Step-by-step explanation:
Given that:
Number of samples, n = 5
Proportion, p = 80% = 0.8
P(x = 2)
Using binomial distribution formula ;
P(X = x) = nCx * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.8^2 * (1 - 0.8)^(5-2)
P(x = 2) = 5C2 * 0.8^2 * 0.2^3
P(x = 2) = 10 * 0.64 * 0.008
P(x = 2) = 0.0512
= 0.05 ( nearest hundredth)
find angle X on the given figure. m
Answer:
x = 51°
Step-by-step explanation:
In a rhombus, the diagonals bisect the angles, thus
∠ BAE = ∠ DAE = 39° , then ∠ A = 78°
∠ ADE = ∠ CDE = x , then ∠ D = 2x
In a rhombus, consecutive angles are supplementary
∠ A and ∠ D are consecutive angles , thus
78 + 2x = 180 ( subtract 78 from both sides )
2x = 102 ( divide both sides by 2 )
x = 51°
Answer:
X=51

answers for the 2 boxes please:)
Answer:
(6, - 9 )
Step-by-step explanation:
Given the 2 equations
6x + 2y = 18 → (1)
- 4x - 2y = - 6 → (2)
Adding the 2 equations term by term will eliminate the y- term, that is
2x + 0 = 12
2x = 12 ( divide both sides by 2 )
x = 6
Substitute x = 6 into either of the 2 equationsand solve for y
Substituting into (1)
6(6) + 2y = 18
36 + 2y = 18 ( subtract 36 from both sides )
2y = - 18 ( divide both sides by 2 )
y = - 9
solution is (6, - 9 )

Your friend used the proportion 40/100 = 80/? To find 40% of 80 and says that the answer is 200. Complete the explanation as to why your friend is incorrect and find the correct answer.
Answer: See explanation
Step-by-step explanation:
My friends calculation is wrong. 40% of 80 is not 200. It is:
= 40% of 80
= 40/100 × 80
= 0.4 × 80
= 32
He should have represented the missing number by x. Therefore,
40/100 = 80/x
Cross multiply
(40 × x) = (80 × 100)
40x = 8000
x = 8000/40
x = 200

0.1(0.5m+6)=2
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.

Answer:
(-4 , 8)
Step-by-step explanation:
The x-axis is the horizontal line. In this case, if you are reflecting over the x-axis, you are flipping the sign of the y-coordinate.
Same with the y-axis. If you are reflecting over the y-axis, you are flipping the sign of the x-coordinate.
In this case, reflect across the x-axis. Flip the sign of the y: (x , y)

x + 4y = 16
-X + 3y = -2
Answer:
(8, 2 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 16 → (1)
- x + 3y = - 2 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 + 7y = 14
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(2) = 16
x + 8 = 16 ( subtract 8 from both sides )
x = 8
solution is (8, 2 )

If DE = 16x - 3, EF = 9x + 11, and DF = 52, find HG.
*see attachement for diagram
Answer:
HG = 25.6
Step-by-step explanation:
Given:
DE = 16x - 3
EF = 9x + 11
DF = 52
Required:
HG
SOLUTION:
✔️First, find the value of x
Thus, since DE is congruent to EF, therefore:
16x - 3 = 9x + 11
Collect like terms
16x - 9x = 3 + 11
7x = 14
Divide both sides by 7
x = 2
✔️Find EH:
Since diagonals of a rhombus are perpendicular, therefore ∆EHF is a right triangle.
Thus, we would use pythagorean theorem to find EH
EH² = EF² - HF²
EF = 9x + 11
Plug in the value of x
EF = 9(2) + 11 = 18 + 11
EF = 29
HF = 52/2 = 26 (diagonals bisect each other)
EH² = 29² - 26² = 165
EH = √165
EH = 12.8 (nearest tenth)
✔️Find HG:
HG = 2(EH) (diagonals bisect each other)
HG = 2(12.8)
HG = 25.6
The measure of HG is 25.6
Properties of a square.For a square, all the sides of the square are equal
Given the following information
DE = 16x - 3EF = 9x + 11DF = 52,
First, find the value of x
Since DE is congruent to EF, therefore:
16x - 3 = 9x + 11
Collect like terms
16x - 9x = 3 + 11
7x = 14
x = 2
Find the measure of EH:
Since the diagonals of a rhombus are perpendicular, therefore ∆EHF is a right triangle.
Thus, we would use Pythagorean theorem to find EH
EH² = EF² - HF²
EF = 9x + 11
Plug in the value of x
EF = 9(2) + 11 = 18 + 11
EF = 29
HF = 52/2 = 26 (diagonals bisect each other)
EH² = 29² - 26² = 165
EH = √165
EH = 12.8 (nearest tenth)
Find the measure of HG:
HG = 2(EH) (diagonals bisect each other)
HG = 2(12.8)
HG = 25.6
Hence the measure of HG is 25.6

y∝√x If y=60 when x=36 find,y when x=16
Answer:
y = 10√16) = 40
Step-by-step explanation:
This says, "y is proportional to the square root of x." We are told that y = 60 when x = 36. Find the formula for this function. Then, determine what value y will take on when x = 16.
y = k√x becomes 60 = k√36, or 60 = 6k. Then k must be 10, and the formula is y = 10√x.
If x = 16, y = 10√16) = 40
