Step-by-step explanation:
[tex]2 \times \dfrac{1}{2} \: kg \\ \\ = \frac{5}{2} kg \\ \\ = 2.5kg[/tex]kg of biscuit cost $ 15 .
We have been asked to find the cost of 2Kg of biscuits.
First Let's find the cost of 1Kg biscuit
[tex] \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = \dfrac{15}{2.5} \\ \\ \: \: \tt\implies \: cost \: of \: 1 \: kg \: biscuit \: = 6 \: dollar[/tex]
Then Cost of 2Kg biscuit would be
[tex] \tt\implies \: cost \: of \: 1kg \: biscuit \: = 2 \times 6 \\ \\ \tt\implies \: cost \: of \: 1kg \: biscuit \: = \: 12 \: dollar[/tex]
Hence, the cost of 2 kg biscuit is 12$ .

Find the area of each figure in square units.
show work
and explain how you got your answer
Answer:
20 square units
Step-by-step explanation:
The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.
Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.
A = bh
A = (5 units)(4 units) = 20 units²
The area is 20 square units.

Help i don’t understand this question
Answer:
828 in²
Step-by-step explanation:
To find the surface area of a triangular prism, you find the area of each side and add them together.
Find the area of each rectangular side:
Side 1 : 9 × 20 = 180 in²
Side 2 : 15 × 20 = 300 in²
Side 3 : 12 × 20 = 240 in²
Find the area of the triangular sides:
Area of a Triangle = [tex]\frac{1}{2}[/tex]bh
As you can see, 9 and 12 both work as the height/base for the triangular sides, so
Δ Side 1 = [tex]\frac{1}{2}[/tex]bh = [tex]\frac{1}{2}[/tex](9)(12) = 54
Δ Side 2 is also 54.
Add the areas of all the sides together:
180 + 300 + 240 + 54 + 54 = 828 in²

Find the value of xx, yy, and zz, in the rhombus below.
Answer:
Step-by-step explanation:
A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
3x - 4 = 3y + 8 = -2x - 9 = 39
The value of x is 43/3
The value of y is 31/3
The value of z is -24
What is a rhombus?A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.
We have,
Rhombus:
All four sides are equal.
So,
3x - 4 = 3y + 8 = -2x - 9 = 39
Now,
3x - 4 = 39
3x = 39 + 4 = 43
3x = 43
x = 43/3
3y + 8 = 39
3y = 39 - 8
3y = 31
y = 31/3
-2z - 9 = 39
-2z = 39 + 9
-2z = 48
z = -24
Thus,
The value of x is 43/3
The value of y is 31/3
The value of z is -24

If the radius of a circle is decreased by 20%, find the percentage decrease in its area.
Answer:
36%
Step-by-step explanation:
Area of circle is
[tex]\pi {r}^{2} [/tex]
If the radius is decreased by 20%. Then the radius will be
80% of the original radius.
So our radius is 0.8.
So our area is
[tex]\pi(0.8r) {}^{2} [/tex]
[tex]\pi(0.64 {r}^{2} )[/tex]
Since pi is constant, the radius only really matters.
We went from
[tex]1 {r}^{2} [/tex]
to
[tex]0.64 {r}^{2} [/tex]
So our area will decrease by 36%
Proof: Let the radius be 10.
So the area of circle will be
[tex]\pi(10) {}^{2} = 100\pi[/tex]
Let our other radius is 8 because 8 is a 20% decrease of the orginal radius
[tex]\pi(8) {}^{2} = 64\pi[/tex]
Next, we subtract the area to find decrease in area
[tex]100\pi - 64\pi = 36\pi[/tex]
Since pi is constant, we can ignore it so our decrease in area is 36%
the area of rectangle is x²+5x-36 sq. unit. its length and breadth is reduced by 2/2units. find new area of rectangle
Step-by-step explanation:
length × breadth = x² + 5x - 36
let's find, what expression was multiplied by what expression to give that result.
first we see, we have a pure x² term.
so, both start with (x + ...) or (x - ...).
then we see the last (constant) term -36.
so, we have a
(x + a)(x - b)
situation.
36 is the product of
6×6
9×4
12×3
18×2
the term +5x tells us that the difference between a and b must be 5. and a as the positive number must be bigger to give us the "+" (the multiplication contains "... + ax - bx ...").
and that means a = +9, b = -4
so, the original area calculation was
(x + 9)(x - 4) = x² + 5x - 36
when we decrease both factors by 2, we get
(x + 9 - 2)(x - 4 - 2) = (x + 7)(x - 6) = x² + x - 42
that is the new area of the rectangle.

The distance between City A and City B is 250 miles. A length of 1.6 feet represents this distance on a
certain wall map. City C and City D are 2.24 feet apart on this map. What is the actual distance
between City C and City D?
The actual distance between City C and City D is ? miles
Answer:
Y = city C - city D = 2.24 ft
2.24 ft / (1.6 ft / 250 mi) = 350 mi distance between C and D
Note: 250 mi / 1.6 ft = 156.25 mi / ft
156.25 mi / ft * 2.24 ft = 350 mi

P(N=8)
P(N>8)
P(N<8)
P(7 8)
Using the normal distribution, it is found that P(X = 8) is equals to zero.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.As in any continuous distribution, the probability of an exact value, that is, P(X = x), is of 0.Hence, from the last bullet point, it is found that P(X = 8) is equals to zero.

Step-by-step explanation:
In a class of 25 students, 7 students have 2 brothers or sisters. 4 students have 1 brother or sister. 3 students do not have any brothers or sisters. 6 students have 3 brothers or sisters. The remaining students have 4 brothers or sisters.
Part A
Use the drop-down menus to make the statement true.
The scale of the line plot should have Choose... (0, 1, 7, 8) as its least data value and Choose... (3, 4, 7, 25) as its greatest data value.
Part B
Use the drop-down menus to make each of the statements about the number of dots true.
There will be Choose... (1, 2, 3, 4) dots above 1.
There will be Choose... (4, 5, 6, 7) dots above 4.
There will be three dots above Choose... (0, 1, 2, 3)
Using the basis of how we must represent data on a graph, we can write:
A) The scale is 1, and the maximum value is 7.
B)
Above 1 we already know that there must be 4 dots. Above 4, there must be 6 dots. We only will have 3 dots above the 0 (3 students have 0 brothers or sisters).How to correctly represent the data?
First, we know that the sample has 25 people in it, an we measure the number of brothers, in such a way that the number of brothers/sisters goes from 0 to 5.
Then, the horizontal axis must go from 0 to 4, in such a way that above the 0 we have 3 dots (because 3 students have 0 brothers or sisters), above the 1 we have 4 dots (because 4 students have one brother or sisters), and so on.
7 students have 2 brothers or sisters (that is the largest number) so the vertical axis must go from 0 to 7.
A) The scale of the line plot is 1, each dot represents 1 student. And the greatest value is 7 (for the students with 2 brothers or sisters).
B)
Above 1 we already know that there must be 4 dots. Above 4, there must be 6 dots. We only will have 3 dots above the 0 (3 students have 0 brothers or sisters).If you want to learn more about plotting data, you can read:
