Final answer:
A French dessert chef can make 30 portions of sorbet from 3 kilograms, with each portion weighing 1/10 of a kilogram, by simply dividing the total weight by the weight of one portion.
Explanation:
The subject of this question is Mathematics, specifically related to division and units of measurement. To find out how many portions each weighing 1/10 of a kilogram can be made from 3 kilograms of sorbet, we divide the total amount of sorbet by the weight of one portion. Therefore, we perform the division:
Determine the weight of one portion: 1/10 kg.
Divide the total weight of sorbet by the weight of one portion: 3 kg ÷ (1/10 kg).
The division gives us the result of 30 portions because 3 ÷ (1/10) is equivalent to 3 × 10.
So, a French dessert chef can create 30 portions of sorbet, with each portion weighing 1/10 of a kilogram.

find the inverse of y=x2-10x
y = x^2 - 10x + 25 - 25
y = (x-5)^2 - 25
y+25 = (x-5)^2
x-5 = +/-sqrt(y+25)
And you get TWO inverses:
x = 5 + sqrt(y+25), for x>=5
x = 5 - sqrt(y+25), for x<=5
Answer:
[tex]y=5\pm \sqrt{(25+x)}[/tex]
Step-by-step explanation:
We are asked to find the inverse for the function [tex]y=x^2-10x[/tex].
We know that to find inverse, we interchange x and y values and then solve for y.
After interchanging x and y values, we will get:
[tex]x=y^2-10y[/tex]
Switch sides:
[tex]y^2-10y=x[/tex]
[tex]y^2-10y-x=x-x[/tex]
[tex]y^2-10y-x=0[/tex]
Now, we will use quadratic formula to solve for y.
[tex]y=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
[tex]y=\frac{-(-10)\pm \sqrt{(-10)^2-4(1)(-x)}}{2(1)}[/tex]
[tex]y=\frac{10\pm \sqrt{100+4x}}{2}[/tex]
[tex]y=\frac{10\pm \sqrt{4*25+4x}}{2}[/tex]
[tex]y=\frac{10\pm \sqrt{4(25+x)}}{2}[/tex]
[tex]y=\frac{10\pm 2\sqrt{(25+x)}}{2}[/tex]
[tex]y=5\pm \sqrt{(25+x)}[/tex]
Therefore, the inverse function for our given function would be [tex]y=5\pm \sqrt{(25+x)}[/tex].

A right triangle has legs that are 15 feet and 25 feet long.
What is the length of the hypotenuse?
15^2 + 25^2 = X62
225 + 625 = x^2
850 = x^2
x = 5sqrt(34)
if you need it as a decimal = 29.1547
Answer: The length of the hypotenuse is 5√34 units.
Step-by-step explanation: Given that a right-angled triangle has legs of length 15 ft and 25 ft.
We are to find the length of the hypotenuse.
As shown in the attached figure, AB and BC are the legs of the right-angled triangle ABC. AC is the hypotenuse of the triangle.
Also, AB = 15 ft and BC = 25 ft.
From Pythagoras theorem, we have
[tex]AC^2=AB^2+BC^2\\\\\Rightarrow AC^2=(15)^2+(25)^2\\\\\Rightarrow AC^2=225+625\\\\\Rightarrow AC^2=850\\\\\Rightarrow AC=\sqrt{850}\\\\\Rightarrow AC=5\sqrt{34}.[/tex]
Thus, the length of the hypotenuse is 5√34 units.

The table below shows data from a survey about the amount of time students spend doing homework each week. The students were either in college or in high school:
High Low Q1 Q3 IQR Median Mean σ
College 50 5 7.5 15 7.5 11 13.8 6.4
HS 16 0 9.5 14.5 5 13 . 10.7 5.3
Which of the choices below best describes how to measure the spread of this data? (Hint: Use the minimum and maximum values to check for outliers.) (2 points) A:Both spreads are best described with the IQR.
B:Both spreads are best described with the standard deviation.
C:The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
D:The college spread is best described by the standard deviation. The high school spread is best described by the IQR.
Answer:
Option A is correct
Step-by-step explanation:
Given is a table which shows data from a survey about the amount of time students spend doing homework each week.
College HS
High 50 16
Low 5 0
Q1 7.5 9.5
Q3 15 14.5
IQR 7.5 5
Median 11 13
Mean 13.8 10.7
Std dev 6.4 5.3
1.5IQR 11.25 7.5
Q1-1.5IQR -9.38 -12
Q3+1.5IQR 37.5 29.5
WE find that there is only one outlier in college with 50 as high.
Except that all others are well within IQR range. Hence outliers are minimum
So option A is right.
Final answer:
To determine the spread of data on student homework hours, IQR and standard deviation are used. The college data's spread is best described by IQR, while the high school data's spread is best described by standard deviation, making Option C the most suitable choice.
Explanation:
To measure the spread of the data for the amount of time students spend doing homework each week, we have two primary measures: the Interquartile Range (IQR) and the standard deviation (σ). IQR represents the difference between the third quartile (Q3) and the first quartile (Q1) and describes the spread of the middle 50% of the data. The standard deviation indicates how much the values in the dataset deviate from the mean, which can help in understanding the overall spread including potential outliers.
When dealing with outliers, it's important to consider that potential outliers are typically identified as values that are more than 1.5 × IQR above Q3 or below Q1. We would use the minimum (Low) and maximum (High) values provided alongside the IQR to check for outliers. For the college data, with a High of 50 and a Low of 5, the range is 45. For high school, the range is 16. Outliers could potentially affect the standard deviation significantly, making IQR a better measure for the middle spread of data.
Based on this, the college data with a wider range may be more affected by outliers, whereas the high school data with a smaller range may not. Therefore, the spread for the college data can be better described by the IQR, while the standard deviation can be a good measure for the high school data. This suggests that Option C: "The college spread is best described by the IQR. The high school spread is best described by the standard deviation." is the most suitable choice.
If f is differentiable at x = c, then f is continuous at x = c.
True
False
Answer:
This is true!
Step-by-step explanation:
P.S: keep in mind that the opposite is not true! If f is continuous at x = c, then f is NOT differentiable at x = c.
:)))
If f is differentiable at x = c, then f is continuous at x = c is not true.
What is differentiable?Any point inside the range of a function's purview has a derivative, making it a computable function of one real variable. In these other phrases, each interior site in the domain of an invertible method's graph does indeed have a non-vertical line segment.
F is NOT differentiable at x = c if it is continuous at x = c.
When working with units, this quality is highly helpful since, if a curve is discrete, we automatically infer that it is indeed continuous.

Which answer represents the series in sigma notation?
[tex]\sum^5_{j=1} (5j-12)[/tex] represents the series in sigma notation.
What is sigma notation?The symbol Σ (sigma) is generally used to denote a sum of multiple terms. This symbol is generally accompanied by an index that varies to encompass all terms that must be considered in the sum.
Given is a series (-7 + (-2) + 3 + 8 + 13), we need to define it in sigma notation,
Therefore,
For j = 1 up to j = 5
j = 1
(5j - 12) = (5(1) - 12) = 5 - 12 = - 7
j = 2
(5j - 12) = (5(2) - 12) = 10 - 12 = - 2
j = 3
(5j - 12) = (5(3) - 12) = 15 - 12 = 3
j = 4
(5j - 12) = (5(4) - 12) = 20 - 12 = 8
j = 5
(5j - 12) = (5(5) - 12) = 25 - 12 = 13
This gives us the given series,
(-7 + (-2) + 3 + 8 + 13)
Hence, [tex]\sum^5_{j=1} (5j-12)[/tex] represents the series in sigma notation.

It takes 4 pounds of grapes to make 1 pound of raisins. How many pounds of grapes would you need to make 3000 pounds of raisins?
Final answer:
To make 3000 pounds of raisins, you would need 12000 pounds of grapes, as it takes 4 pounds of grapes to make 1 pound of raisins.
Explanation:
The question asks us to find out how many pounds of grapes are needed to make 3000 pounds of raisins.
Given that it takes 4 pounds of grapes to make 1 pound of raisins, we can set up a proportion to solve for the total weight of grapes needed. The proportion will be:
4 pounds of grapes / 1 pound of raisins = x pounds of grapes / 3000 pounds of raisins
Multiplying both sides of the proportion by 3000 pounds of raisins gives us:
4 pounds of grapes x 3000 pounds of raisins = x pounds of grapes x 1 pound of raisins
So,
x = 4 x 3000
x = 12000 pounds of grapes.
Therefore, you would need 12000 pounds of grapes to make 3000 pounds of raisins.

Answer:
[tex](1.12 x 10^5) (6.06 x 10^5) = 6.787 x 10^{10}\\[/tex]
[tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2} = 6.14 * 10 ^ {-3}\\[/tex]
Step-by-step explanation:
To solve this problem we must solve all 4 operations.
For the first one we have:
[tex](1.12 x 10^5) (6.06 x 10^5)[/tex]
When we have multiplication of powers of equal base (10) the same base is placed and the exponents are added
So:
[tex]1.12 * 6.06 x 10^{5+5} = 6.787 x 10^{10}\\[/tex]
Therefore the answer to this question is correct.
For the second question we have:
[tex](2 x 10^1) (3.0 x 10^1)[/tex]
Then following the same procedure as in the previous question we have:
[tex]2 * 3.0 x 10 ^ {1 + 1} = 6 x 10 ^ 2\\[/tex]
Then the answer shown in the statement is not correct, because 10 must be squared, product of the sum of its exponents (1 + 1)
For the third question we have:
[tex](2,775 x 10^{-4}) (4,775 x 10^4)\\2.775 * 4.775 x 10 ^{(- 4) +4} = 13.251 x10 ^ 0\\[/tex]
Then it is verified that the answer for this operation is no correct
[tex]13.25\neq 1.325[/tex]
Finally, for the fourth question we have:
[tex]\frac{5}{(8.14 x 10 ^ 2)}\\[/tex]
This we can write it as:
[tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2}\\[/tex]
In division of powers of equal base (10 in this case) the same base is placed and the exponents are subtracted:
[tex]\frac{0.5}{8.14 x 10 ^ {1-2}} = 0.0614 x 10 ^ {-1} = 6.14 * 10 ^ {-3}\\[/tex]
Finally, the problems that show correct answers are:
[tex](1.12 x 10^5) (6.06 x 10^5) = 6.787 x 10^{10}\\[/tex]
[tex]\frac{0.5 x 10 ^ 1}{8.14 x 10 ^ 2} = 6.14 * 10 ^ {-3}\\[/tex]

Answer:
1. C) Inverse Property of Multiplication
2. None of these. The answer is Associative property of Addition
3. C) Inverse Property of Multiplication
4. None of these. The answer is Associative property of Multiplication
Step-by-step explanation:
1.
Given a number a , the inverse property of multiplication states that
a * 1/a = 1
and 1/a is called the multiplicative inverse of a.
So 8 * 1/8 = 1 features the inverse property of multiplication where a = 8.
2.
Given three numbers a,b,c , the associative property of addition states that a + (b + c) = (a + b) + c
In this case, a = -5, b = 8 and c = 10
3.
-4 x -1/4 = 1 features the inverse property of multiplication where a = -4.
4.
Given three numbers a,b,c , the associative property of multiplication states that (a * b) * c = a * (b * c)
In this case, a = a, b = b and c = 3
