Aisha recorded the heights, in centimetres, of some girls.
She used her results to work out the information in this table,
Least height
142 cm
Lower quartile
154 cm
Interquartile range
17 cm
Median
162 cm
Range
40 cm
Aisha drew this box plot for the information in the table.
The box plot is not fully correct.
130
140
180
190
150 160 170
Height (centimetres)
Write down the two things Aisha should do to make the box plot fully correct.
Answers
Answer:
The median is marked at 161cm instead of 162cm.
The right part of the box (the upper quartile) is marked at 172cm, while the interquartile range is 17cm, so the upper quartile should be at 154cm + 17cm = 171cm.
Median and higher quartile are the two changes that Aisha should do to make the box plot fully correct.
What is box plot?Box plot is a type of chart often used in explanatory data analysis. A graphical rendition of statistical data based on the minimum, first quartile, median, third quartile, and maximum.
For the given situation,
Least height - 142 cm
Lower quartile - 154 cm
Inter quartile range - 17 cm
Median - 162 cm
Range - 40 cm
The higher quartile can be calculated as
Higher quartile = Lower quartile + Inter quartile range
⇒ Higher quartile = [tex]154+17[/tex]
⇒ Higher quartile = [tex]171[/tex]
From the box plot shown, the values of median and higher quartile are drawn wrong.
In diagram,
The median is at 161 but it should be drawn in 162.The higher quartile is at 172 but it should be drawn in 171.Hence we can conclude that median and higher quartile are the two changes that Aisha should do to make the box plot fully correct.

Terrell got 1 3/4 pounds of ground meat and 2 1/6 of ground chicken. he used 1 2/3 pounds of ground chicken to make a casserole. how much ground chicken did he have left?
Answers
Answer:
Okay so we have to solve this in separate parts. Like so, its wiill go like this: 2+ 1/6 - 1 - 2/3. So we see that we have 2 and 1 as whole. Subtract 2 - 1 is 1 right. Now for fractional part 1/6 - 2/3. Since its uneven, we have to find the LCD which is 6. This forms of our fractions into 1/6- 4/6. 1/6 - 4/6 is 3/6. simplify it would result in 1/2. The amount of ground chicken that Terrell has left is 1/2.

2.For the equation in above evaluate the notation using the values below. Please
enter the exact value.
X1 =0
Y1 = 5
Z1 = 0
X2 = 1
Y2 = 26
Z2 = -2
X3 = 12
Y3 = -2
Z3 = 3
X4 = -1
Y4 = 25
Z4 = 24
Answers
Answer:
(a) Expanded form:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
(b) The value of the expression: -21
Step-by-step explanation:
Given
[tex]\sum \limit^4_{i=1}\ ((X_i+X_iY_i) - X_iZ_i)[/tex]
Solving (a): The expanded form:
This means that we substitute the values of i from 1 to 4 in the above expression.
So, the expression becomes:
[tex]((X_1 + X_1Y_1) - X_1Z_1) + ((X_2 + X_2Y_2) - X_2Z_2) + ((X_3 + X_3Y_3) - X_3Z_3) + ((X_4 + X_4Y_4) - X_4Z_4)[/tex]
Solving (b): The value of the expression
To do this, we simply substitute the given values of X1, X2....... in the expression.
This gives:
So, the expression becomes:
[tex]((0 + 0*5) - 0*0) + ((1 + 1*26) - 1*-2) + ((12 + 12*-2) - 12*3) + ((-1 + -1*25) - -1*24)[/tex]
Simplify each bracket
[tex]((0 + 0) - 0) + ((1 + 26) +2) + ((12 -24) - 36) + ((-1 -25) +24)[/tex]
[tex]0 + 29 -48 -2[/tex]
[tex]-21[/tex]
Hence, the result of the expression is -21

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=". The word equation and its cognates in other languages may have subtly different meanings; for example, while in English, any equality is an equation. Solving an equation containing variables consists of determining which values of the variables make the equality true.

Given function is,
f(x) = -4(x - 3)² + 1
A). Negative sign of the coefficient (-4) tells that the parabola opens downwards.
And 4 represents that the parent function is stretched vertically by 4 units.
B). By comparing this equation with the vertex form of the quadratic function,
f(x) = a(x - h)² + k
Here, (h, k) is the vertex of parabola.
Vertex of the given parabola → (3, 1)
C). Axis of symmetry → x = 3
D). Domain of the given quadratic function → (-∞, ∞)
Range of the given function → (-∞, 1)
