40.
Step-by-step explanation:
Base times height. This is a rhombus. 4 x 10 = 40. If you chop off the triangle to the right and place it on the left where 5 is, it'll be a rectangle. Formula for a rhombus is B x H, Base is 10, height is 4, and you get 40.

The median and interquartile range is used as a measure of center and measure variability to compare populations when:
When there are outliers in the data sets
When there are no big gaps in the middle of the data sets
When the plots representing the data are symmetrical
When there are no outliers in the data set
We have,
Use the median and interquartile range as measures of center and variability to compare populations shown on a box plot in the following scenarios:
- When there are outliers in the data sets:
The median and interquartile ranges are resistant to outliers, meaning they are not significantly influenced by extreme values.
- When there are no big gaps in the middle of the data sets:
The median is a measure of the center that is not affected by extreme values or outliers, making it appropriate when there are no significant gaps or clusters in the middle of the data sets.
The interquartile range, which measures the spread of the central 50% of the data, is also less influenced by extreme values compared to the range or standard deviation.
- When the plots representing the data are symmetrical:
The median is a suitable measure of center for symmetrical distributions, where the data is evenly distributed around the middle.
In such cases, the median provides a representative measure of the central tendency.
The interquartile range also captures the spread of the data within the central 50% and can be used as a measure of variability.
- When there are no outliers in the data set:
While the median and interquartile ranges are resistant to the influence of outliers, they can still be used effectively to compare populations when no outliers are present.
In the absence of outliers, the median accurately represents the central tendency, and the interquartile range provides a robust measure of variability.
Therefore,
When there are outliers in the data sets
When there are no big gaps in the middle of the data sets

The Smiths spend 8% of their budget on entertainment. Their total budget this year is $3,000 more than last year, and this year they plan to spend $3,600 on entertainment. What was their total budget last year?
Answers
Answer:
$6600
Step-by-step explanation:
3000+3600=6600
Answer:
Their total budget was $42000 last year.
Step-by-step explanation:
8% = 0.08
1.) 0.08( x + 3000 ) = 3600
2.) Distribute:
0.08x + 240 = 3600
3.) Use inverse operation to solve. Subtract 240 from each side:
0.08x + 240 = 3600
- 240 = - 240
0.08x = 3360
3.) divide 0.08 from each side:
0.08x = 3360
x = 42000

Final answer:
The quadratic trinomial x² - 10x + 4.75 is solved using the quadratic formula. The coefficients identified are a=1, b=-10, and c=4.75, and when substituted into the formula, it yields solutions x = 7 and x = 3.
Explanation:
Solving a Quadratic Equation Using the Quadratic Formula
To solve the quadratic trinomial x2−10x + 4.75 using the quadratic formula, 'x' equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a', we first identify the coefficients a, b, and c from the trinomial, which are in the standard form of ax2 + bx + c = 0.
Identifying coefficients: a = 1 (the coefficient of x²), b = -10 (the coefficient of x), c = 4.75 (the constant term).
Plugging the coefficients into the quadratic formula: x = −(-10) ± √((-10)2 − 4(1)(4.75)) / (2(1)).
Calculating the discriminant: Calculate b2 − 4ac which is 100 − 19.
Square root step: Take the square root of the discriminant, which is √81.
Final calculation: Compute the two possible values for x which are x = 5 + √81 / 2 and x = 5 − √81 / 2.
Solution: The roots are x = 5 + 9/2 and x = 5 − 9/2, simplifying to x = 7 and x = 3.
The final answer for the roots of the equation x² − 10x + 4.75 = 0 using the quadratic formula are x = 7 and x = 3.

The total surface area of the composite figure is 282 square units. Thus, the correct option is C.
What is the area?The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.
The top two nets are triangular prisms connected to the bases of a rectangular prism. The composite image is made up of all three prisms. The dark sections represent faces shared by the prisms.
The total surface area of the composite figure is calculated as,
A = 4(1/2 x 3 x 4) + 2(5 x 10) + 2(4 x 10) + 2(3 x 3) + 2(3 x 10)
A = 24 + 100 + 80 + 18 + 60

Given:
AB = 9 in, BC = 2 in
DE = 3 in, EF = 3 in
To find:
The area of the shape
Solution:
ABCH is a rectangle.
Area of rectangle = length × width
= AB × BC
= 9 × 2
Area of ABCH = 18 in²
GDEF is a square.
Area of square = side × side
= DE × EF
= 3 × 3
Area of GDEF = 9 in²
Area of the shape = Area of ABCH + Area of GDEF

We have to convert angle into radian.
We know that
Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]

Answers
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{3}[/tex] 81 = n, then
81 = [tex]3^{n}[/tex]
Note that 81 = [tex]3^{4}[/tex] , thus
[tex]3^{4}[/tex] = [tex]3^{n}[/tex]
Since the bases are equal then equate the exponents
n = 4
The value of log Subscript 3 Baseline 81 (i.e Log₃ 81) obtained is 4
Data obtained from the question Log₃ 81 =? How to determine the value of Log₃ 81Let Log₃ 81 be equal to n i.e
Log₃ 81 = n
The value of n can be obtained as follow:
Log₃ 81 = n
81 = 3ⁿ
Express 81 in index form with 3 as the base
3⁴ = 3ⁿ
Cancel out 3
n = 4
From the calculation made above, we can conclude that the value of log Subscript 3 Baseline 81 (i.e Log₃ 81) is 4

Find the inverse of function f.
f(x) = 1/3 - 1/21x
Answers
Answer:f⁻ (x) = 7 - 21 x.
We can also write it as:
y = 1/3 - 1/21 x
1 / 21 x = 1 / 3 - y
x = 7 - 21
To find the inverse of the function f(x) = 1/3 - 1/21x, interchange x and y in the equation, solve for y, and denote it as the inverse function, resulting in [tex]f^-1(x) = 7 - 21x[/tex].
The student is asking to find the inverse of the function f(x) = 1/3 - 1/21x. To find the inverse function, we need to first rewrite the function in the form y = 1/3 - 1/21x. Next, we switch x and y to get x = 1/3 - 1/21y. Then, solve for y, giving us the inverse. The steps are:
Replace f(x) with y: y = 1/3 - 1/21xInterchange x and y: x = 1/3 - 1/21yMultiply both sides by 21 to clear the fraction: 21x = 7 - yAdd y to both sides and subtract 7 from both sides: y + 21x = 7Isolate y: y = 7 - 21xFinally, replace y with f-1(x) to denote the inverse function:f-1(x) = 7 - 21x
