In a survey, 105 students like Maths, 25 didn’t like Maths, 95 didn’t like Science, 83 like Maths but not Science. Find by drawing Venn-diagram. How many students like –
a. At least one subject
b. Exactly one subject
c. At most one subject
Answer:
a = 118
b = 96
c = 108
Step-by-step explanation:
105 + 25 = 130
130 students
83 = maths ONLY
105 - 83 - 22
22 = maths and science
95 didnt like science
130 - 95 = 35
35 liked science
35 - 22 = 13
13 people liked science ONLY
83 + 22 + 13 = 118
130 - 118 = 12
leaving 12 as the people who like neither
130 - 22 = 108 = people who like 0 or 1 subject (at most one subject)
Solve: (2x - 3)^2 = -4
Answer:
No real solutions;
[tex]x=i+1.5[/tex]
Step-by-step explanation:
The easiest method to solve an algebraic equation is to use inverse operations. This applies to the given equation;
[tex](2x-3)^2=-4\\[/tex]
- Take the square root of both sides
[tex]\sqrt{}[/tex]
==================================================================
As one can see, the right side is a negative number. However, one cannot take the square root of a negative number and get a real result. Therefore, one must use imaginary numbers. Remember, the imaginary unit ([tex]i[/tex]) represents ([tex]\sqrt{-1}[/tex]).
==================================================================
[tex]2x-3=2i[/tex]
- Add (3) to undo the (-3)
[tex]+3[/tex]
[tex]2x=2i+3[/tex]
- Divide by (2) to remove the coefficient of (2x)
÷[tex]2[/tex] ÷
[tex]x=\frac{2i+3}{2}[/tex]
Simplify,
[tex]x=i+1.5[/tex]

A shipping container is in the shape of a right rectangular prism with a length of 2 feet, a width of 3 feet, and a height of 5 feet. The container is completely filled with contents that weigh, on average, 0.84 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
13 pounds
Step-by-step explanation:
volume = base area × height
area of a rectangular triangle = a×b/2
Vp = (2×3/2) × 5 = 3×5 = 15 ft³
weight of contents = 15 × 0.84 = 12.6 pounds = 13 pounds rounded.
Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK
Answer:
IK = 20
Step-by-step explanation:
If Point J is on the line segment IK, then;
IK = IJ + JK
Given that
IJ = 4
IK = 5x
JK = 4x
Substitute into the expression
5x = 4 + 4x
5x - 4x = 4
x = 4
Get the value of IK
IK = 5x
IK = 5(4)
IK = 20
Hence the numerical length of IK is 20
find out the shortest distance between the point (3,4) and the line 3x+4y+25=0
Answer:
Hence, shortest distance is 0
Step-by-step explanation:
4y = -3x+25
y = -3/4x + 25/4
When x = 3,
y = -9/4 + 25/4
y = 4
Hence, when x =3,

The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the data. What does this number measure?
Answer:
19 measures the median
Step-by-step explanation:
The dot plot is not shown, but the question can still be answered.
We have:
[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]
[tex]n = 8[/tex]
Calculate the median position using:
[tex]Median = \frac{n + 1}{2}th[/tex]
[tex]Median = \frac{8 + 1}{2}th[/tex]
[tex]Median = \frac{9}{2}th[/tex]
[tex]Median = 4.5th[/tex]
4.5th means the median is the mean of the 4th and 5th item.
We have:
[tex]4th = 18[/tex]
[tex]5th = 20[/tex]
So:
[tex]Median = \frac{18 + 20}{2}[/tex]
[tex]Median = \frac{38}{2}[/tex]
[tex]Median = 19[/tex]

[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
Step-by-step explanation:
2r² + 7r - 1 = 3r²
2r² + 7r - 1 - 3r² = 0
- r² + 7r - 1 = 0
- (r² - 7r + 1) = 0
- (r² - 7r + 1) ÷ - 1 = 0 ÷ - 1
r² - 7r + 1 = 0
[tex]r=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
r² - 7r + 1 = 0
a = 1
b = - 7
c = 1
[tex]r=\frac{-(-7)±\sqrt{(-7)^{2}-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{45 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{(3)(3)(5) } }{2(1)}[/tex]
[tex]r=\frac{7±(\sqrt{3 } )(\sqrt{3})(\sqrt{5}) }{2(1)}[/tex]
[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Two separate equations
[tex]r=\frac{7+3\sqrt{5} }{2}[/tex]
[tex]r=\frac{7-3\sqrt{5} }{2}[/tex]

rhombus wxyz with vertices w(1 0) x(4,-1) y(5,-4) and z(2,-3)
Answer:
W 2,3
X 5,3
Y 1,2
Z 8,4
Step-by-step explanation:
The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the coordinates of the rhombus be represented as WXYZ
where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )
Now , the dilation scale factor is k = 3 centered at origin
So , result of this transformation is an image with the same shape as the original
The coordinates of the dilated figure is W'X'Y'Z'
where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
Hence , the dilation is solved

A box contains 4 marbles: 1 blue, 1 yellow, 1 green, and 1 white. A marble is randomly drawn from the box and a number cube, labeled 1 through 6, is tossed. What is the probability of getting a yellow marble and an odd number? Express as a fraction in simplest form.
Answer:
The answer is 1/8
Step-by-step explanation:
There are 4 marbles in the box and one of them is a yellow marble. The odds of getting a yellow marble fr the box is 1/4.
A number cube labeled 1 through 6 has 6 numbers, which are 1, 2, 3, 4, 5 and 6. The odd numbers in the cube are 1, 3 and 5. The probability of getting an odd number from the cube is 3/6, which is simplified to 1/2.
To find the probability of both cases occurring, both fractions should be multiplied.
1/4 * 1/2 = 1/8

Answer:
Y = 9
Step-by-step explanation:
Answer:
y = 9
Step-by-step explanation:
2 + 4 ( y - 1 ) = 2y + 16
step 1 distribute the 4
4 * y = 4y
4 * -1 = -4
we now have 2 + 4y - 4 = 2y + 16
step 2 combine like terms
2 - 4 = - 2
we now have - 2 + 4y = 2y + 16
step 3 add 2 to each side
-2 + 2 cancels out
16 + 2 = 18
we now have 4y = 2y + 18
step 4 subtract 2y from each side
2y - 2y cancels out
4y - 2y = 2y
we now have 2y = 18
step 5 divide each side by 2
2y / 2 = y
18 / 2 = 9
we're left with y = 9
