Answer:
B) 0.0625
Step-by-step explanation:
f(x) = k / x
f(x)=0.5 when x = 0.3
f(x) = k / x
0.5 = k / 0.3
Cross product
0.5 * 0.3 = k
k = 0.15
What is f(x) when x = 2.4?
f(x) = k / x
f(x) = 0.15 / 2.4
f(x) = 0.0625
The answer is B) 0.0625

Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].
En el club de teatro asistieron 15 alumnos a clases .Si en total son 21 ¿ cual es la razon entre el total de alumnos y los ausentes
Answer:
La razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]
Step-by-step explanation:
En el club de teatro asistieron 15 alumnos a clases. En total, son 21 alumnos. Entonces la cantidad de alumnos ausentes se calcula como la diferencia entre la cantidad total de alumnos y la cantidad de asistentes, esto es:
21 alumnos - 15 alumnos= 6 alumnos
La cantidad de alumnos ausentes es 6.
La razón es la comparación de dos cantidades y se mide como el cociente entre dos números o cantidades comparables entre sí, que se expresa como una fracción. Es decir, la razón entre 2 números a y b es el cociente [tex]\frac{a}{b}[/tex].
Entonces, la razón entre el total de alumnos y los ausentes es [tex]\frac{6}{21} =\frac{2}{7}[/tex]

Plz help solve: Find the side length of a square with an area of 15/6 cm^2
Answer:
1.58 cm
Step-by-step explanation:
Area of a square = length ²
Area of the square = 15/6 cm²
Area of a square = length ²
15/6 = length²
Find the square root of both sides
√15/6 = √length²
√2.5 = length
1.58 cm = length
Alternatively,
√15/6 = √length²
√15/√6 = length
3.87 / 2.45 = length
1.58 cm = length
Therefore, side length of the square = 1.58 cm

The measure of QS.
Solution:
In triangle QRU and QST,
[tex]\angle RQU\cong \angle SQT[/tex] [Common angle]
[tex]\angle QRU\cong \angle QST[/tex] [Corresponding angle]
[tex]\triangle RQU\sim \triangle SQT[/tex] [AA property of similarity]
The corresponding sides of similar triangles are proportional.
[tex]\dfrac{QR}{QS}=\dfrac{QU}{QT}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{25+50}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{75}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{1}{3}[/tex]
On cross multiplication, we get
[tex]3(23)=1(QS)[/tex]
[tex]69=QS[/tex]
Therefore, the measure of QS is 69.

Out of 60 people surveyed 42 respond yes to the server question what is the relative frequency of yes responses
Answer: 7/10
Step-by-step explanation:
Number of people surveyed = 60
Number of people who responded Yes = 42
The relative frequency will be the fraction of those who responded yes divided by the total people surveyed. This will be:
= 42/60
= 7/10.
The relative frequency is 7/10.

Marsha likes to take photos with her new camera.She already has 1427 photos. She just bought her camera 15 days ago and took pictures everyday.Approximately how many pictures did she take each day?
Answer:
About 95
Step-by-step explanation:
If she bought her camera 15 days ago, then you just divide 1427 by 15. You can't take parts of pictures, so it has to be a whole number, so you round.
Answer:
95.1333333333 you should probably round it but thats how many photos she took each day
Step-by-step explanation:
1427/15= photos taken each day

Answer:
Omggg twins I'm doing the Iready too:> Anyway I had that question and I selected 1.62
The average rate of change of function [tex]y= \sqrt[3\\]{x}[/tex] over interval [2,7] to rounding to nearest hundredth is 0.13
The Correct option is (b)
What average function?The Average Rate of Change function is defined as the average rate at which one quantity is changing with respect to something else changing.
i.e., [tex]\frac{f(b)- f(a)}{b-a}[/tex]
It has been asked in the question the average rate of function over interval [2,7].
The values are given in the table.
So, the rate of change of f(x) on interval [a, b] = [tex]\frac{f(b)- f(a)}{b-a}[/tex]
we have, a=2 and b=7
Thus, [tex]\frac{f(b)- f(a)}{b-a}[/tex] = [tex]\frac{\sqrt[3]{7} -\sqrt[3]{2} }{7-2} {[/tex]
=[tex]-\frac{\sqrt[3]{2} }{5}+\frac{\sqrt[3]{7} }{5}[/tex]
=0.1306
≈ 0.13 (rounding off nearest hundredth)

A turtle lives in a garden and a hedgehog lives in the woods. They leave their homes at the same time walk toward each other and meet in 5 hours. The turtle walks 10 meters per hour slower than the hedgehog. If the turtle had left home 4 1/2 hours earlier than the hedgehog had left his home, the two would meet 150m from the woods. Find the distance between the garden and the woods.
Answer:
The answer is 450
Step-by-step explanation:
I got this equation:
x- the speed in which the turtle walks
5x+5(x+10)=4.5x+150+x*(150)/(x+10)
I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.
By solving a system of equations, we will see that the distance is 383m
How to find the distance between the garden and the woods?Let's define the speeds of the animals as:
St = speed of the turtle.Sh = speed of the hedgehog.We know that if they leave their houses at the same time, they meet after 5 hours, so we have:
(St + Sh)*5h = D
where D is the distance we want to find.
We also know that:
St = Sh - 10m/h
And if the turtle leaves 4.5 hours earlier, they meet at 150m from the woods.
This is written as:
St*9.5h + Sh*5h = D - 150m
So we need to solve a system of equations:
St*9.5h + Sh* = D - 150m
St = Sh - 10m/h
(St + Sh)*5h = D
Replacing the second equation into the other two we get:
(Sh - 10m/h + Sh)*5h = D
(Sh - 10m/h)*9.5h + Sh*T = D - 150m
Now we can find Sh on the second one.
Sh*14.5h = D - 150m + 95m
Sh = (D + 150m + 95m)/14.5h = D/14.5h + 16.9 m/h
Replacing that on the other equation we get:
(2*(16.9m/h + D/14.5h) - 10m/h )*5h = D
118.96m + D*(10/14.5) = D
118.96m = D*(1 - 10/14.5)
D = 118.96m/(1 - 10/14.5) = 383m
The distance is 383m

Answer:
x=10.4
Step-by-step explanation:
well 20*5=what? 20*5=100 but then x would have to be a decimal. not a tough one though.
10*x (x being 10) 10*10 would be 100 but then you would have to subtract 4 from it. it's easy. 10 *10.4 is 104.
x would = 10.4 to get this result
