So, the given statement is false.
Step-by-step explanation:
Given , Mr. Flores has 100 pictures in a photo album. Of these picture , 20 show his friends , 50 show his family and 30 show his pet dachshund.
Probability formula:
[tex]P(A)=\frac{\textrm{Number of favorable outcomes to A}}{\textrm {Total number of out comes}}[/tex]
Total number of out come = 100
Number of photo of his family = 50
Therefore the probability of Mr. Flores selecting a picture of his family is
[tex]=\frac{50}{100}[/tex] [tex]=\frac{1}{2}[/tex] [tex]= \frac{5}{10}[/tex]
The probability of Mr. Flores selecting a picture of his friend is [tex]=\frac{20}{100}[/tex] [tex]=\frac{1}{5} = \frac{2}{10}[/tex]
The probability of Mr. Flores selecting a picture of his pet dachshund [tex]=\frac{30}{100}[/tex] [tex]=\frac{3}{10}[/tex]
Since [tex]\frac{5}{10}>\frac{3}{10}>\frac{2}{10}[/tex]
Therefore the probability of Mr. Flores randomly selecting a picture of his family is greater than the probability of randomly selecting a picture Frou -Frou.
So, the given statement is false.

QUESTION 4 of 10: Your restaurant purchases 1,625 bottles of Chablis per year. The annual increase of purchases has been 6%. If this
increase continues for 5 years, what will be your average increase in bottles purchased per year over that time?
a) 110 bottles
b) 190 bottles
c) 260 bottles
d) 400 bottles
Answer:
A - 110
Step-by-step explanation:
So if it is 6% increase you would times the number by 1.06. So you would do this like 5 times:
1,625 x 1.06 = 1722.5
1722.5 x 1.06 = 1825.85
1825.85 x 1.06 = 1935,401
1935.401 x 1.06 = 2051,52506
2051.52506 x 1.06 = 2174,6165636
Now you have the total number of bottles after 5 years, you would find the increase which is 2174.6165636 - 1,625 ≈ 550. 550 / 5 = 110

The average increase in bottles purchased per year over that time is c) 110 bottles.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.
Now it is given that,
Number of bottles purchased per year, a = 1,625
Percentage increase per year, r = 6% = 0.06
Total time period, n = 5 years
Since, the equation of a exponential growth function is given as,
y = a(1 +r)ⁿ
⇒ y = 1625(1 +0.06)⁵
⇒ y = 1625(1.06)⁵
⇒ y = 1625*1.338
⇒ y = 2,175
Therefore, average increase in bottles purchased per year over that time = (2175 - 1625) / 5
= 550 / 5
= 110 bottles
Thus, the average increase in bottles purchased per year over that time is c) 110 bottles.

Inverse property of multiplication: For all real numbers except , a • = 1.
Answer:
[tex]\text{Inverse property of multiplication: For all real numbers except }0,\text{ }a\cdot 1/a=1[/tex]
Explanation:
These are the examples given to illustrate the inverse property of multiplication:
[tex]1/5\cdot 5=1\\\\ \sqrt{2}\cdot (1/\sqrt{2})=1[/tex]
And you must complete the statement to describe the property.
Inverse property of multiplication: For all real numbers except __, a • __ = 1.In the first example, 1/5 and 5 are reciprocal numbers of each other, also known as multiplicative inverses. And the example is showing that the product of 1/5 and its reciprocal is 1.
In the second example, [tex]\sqrt{2}\text{ and }(1/\sqrt{2})[/tex] are reciprocal of each other. Again, the example is showing that the product of those a number at its reciprocal is 1.
That is a general property, that can be written as:
[tex]a\cdot 1/a=1[/tex]
That property is satisfied by any number except 0, because the reciprocal of [tex]0[/tex] , i.e. [tex]1/0[/tex] is not defined.
Then, the statemen is:
[tex]\text{For all real numbers except }0,\text{ }a\cdot 1/a=1[/tex]
The statement that best describes the inverse property of multiplication is: Inverse property of multiplication: For all real numbers except 0, a * a⁻¹ = 1.
This means that if you multiply a number by its reciprocal, you will always get 1.
The examples you provided illustrate this property nicely:
5 * 1/5 = 1
√2 * 1/√2 = 1
Note that the inverse property of multiplication does not hold for the number 0, because the reciprocal of 0 is undefined.
Here is another example of the inverse property of multiplication:
3 * 1/3 = 1
You can check any other real number and its reciprocal, and you will always find that the product is 1.
The inverse property of multiplication is a useful property in mathematics, and it is used in many different areas, such as algebra, calculus, and physics.

The fifth power of the number 27 is equal to 3¹⁵.
To find the fifth power of a number that is equal to 3¹⁵, we need to determine what number raised to the power of 5 gives us 3¹⁵.
Let's call the number we are looking for "x." So, we need to solve the equation:
x⁵ = 3¹⁵
To find x, we can take the fifth root of both sides of the equation:
x = (3¹⁵[tex])^{(1/5)[/tex]
x = 3³
x = 27
This means that if we raise 27 to the power of 5 (27⁵), we will get 3¹⁵ (3 raised to the power of 15).
In conclusion, the number we are looking for is 27, as 27^5 is equal to 3¹⁵.

What number is halfway between .2 and .3
Final answer:
The number halfway between 0.2 and 0.3 is 0.25, which is found by adding the two numbers and dividing the total by 2.
Explanation:
The number halfway between 0.2 and 0.3 can be found by calculating the average of the two numbers. To find the average, you add the two numbers together and then divide by 2.
To show the steps:
Add 0.2 and 0.3 together: 0.2 + 0.3 = 0.5.Divide the sum by 2 to get the midpoint: 0.5 ÷ 2 = 0.25.Therefore, the number that is halfway between 0.2 and 0.3 is 0.25.
The number halfway between 0.2 and 0.3 is 0.25.
To find the number halfway between 0.2 and 0.3, you calculate the average of the two numbers. Here's the step-by-step process:
Add the two numbers together: 0.2 + 0.3 = 0.5.Divide the sum by 2 to get the average: 0.5 / 2 = 0.25.So, the number halfway between 0.2 and 0.3 is 0.25. This method ensures that you find the exact midpoint between two values.
Suppose that receiving stations X, Y, and Z are located on a coordinate plane at the points (4,5), (-6,-6), and (-14,2), respectively. The epicenter of an earthquake is determined to be 10 units from X, 5 units from Y, and 13 units from Z. Where on the coordinate plane is the epicenter located?
Find the coordinates of the epicenter.
Answer:
(-2, -3)
Step-by-step explanation:
A careful graph shows the point (-2, -3) is at the intersection of the circles whose radii are the given distances from the receiving stations.
_____
The simultaneous equations for the circles can be solved algebraically.
The epicenter is 10 units from X, so lies on the circle ...
(x -4)^2 +(y -5)^2 = 10^2
x^2 -8x +16 +y^2 -10y +25 = 100
x^2 +y^2 -8x -10y = 59
__
The epicenter is 5 units from Y, so lies on the circle ...
(x +6)^2 +(y +6)^2 = 5^2
x^2 +12x +36 +y^2 +12y +36 = 25
x^2 +y^2 +12x +12y = -47
__
The epicenter is 13 units from Z, so lies on the circle ...
(x +14)^2 +(y -2)^2 = 13^2
x^2 +28x +196 +y^2 -4y +4 = 169
x^2 +y^2 +28x -4y = -31
__
Subtracting the second equation from each of the other two, we get ...
(x^2 +y^2 -8x -10y) -(x^2 +y^2 +12x +12y) = (59) -(-47)
-20x -22y = 106 . . . . eq1 -eq2
(x^2 +y^2 +28x -4y) -(x^2 +y^2 +12x +12y) = (-31) -(-47)
16x -16y = 16 . . . . . . . .eq3 -eq2
These simultaneous linear equations can be solved a variety of ways. We might use substitution:
x = y+1 . . . . . from eq3 -eq2 divided by 16
10(y +1) +11y = -53 . . . . . from eq1 -eq2 divided by -2
21y = -63 . . . . . . . . . . . . simplify, subtract 10
y = -3
x = y+1 = -2
The epicenter is located at (x, y) = (-2, -3).

Answer:
C. 11
Step-by-step explanation:
First, find the value of "x" by solving the first equation. You need to move every other number to the other side of "x". When you move a number, you have to do the opposite operation to both sides.
5x + 6 = 10 The opposite of +6 is -6.
5x + 6 - 6 = 10 - 6 Subtract 6 from both sides
5x = 10 - 6 The "6" on the left cancelled out. Simplify the right side
5x = 4 The opposite of multiply by 5 is divide by 5
5x/5 = 4/5 Divide both sides by 5
x = 4/5 Value of "x"
Substitute the value of "x", which is 4/5, in the "x" for the second equation.
10x + 3
= 10(4/5) + 3 Multiply 10 and 4/5
= [tex]\frac{10*4}{5}[/tex] + 3 Combine into the numerator
= [tex]\frac{40}{5}[/tex] + 3 Divide the top by the bottom
= 8 + 3 Add
= 11 Value of second equation
Therefore the value of 10x + 3 is 11.

b = 23
Step-by-step explanation:
To solve this system of equations, we can negate one equation and add it to other to cancel out one variable.
Looking at v and b, the coefficients are 6, 4 and 13, 9, respectively.
It would be easier to use the LCM of 6 and 4
[tex]E_1 : 6v + 13b = 377\\E_2: 4v + 9b = 259\\\\4E_1 + (- 6)E_2:\\24v + 52b = 1508\\-24v - 54b=-1554\\\\0v -2b = -46\\-2b = -46\\b = 23\\\\4v + 9(23) = 259\\4v + 207 = 259\\4v = 52\\v = 13\\\\6(13) + 13(23)\\78 + 299\\377[/tex]
Morse code is a way to transmit text using a series of dots or dashes. The Morse Code for "Add" is shown. What fraction of the shapes are dots in the Morse code for "Add"
Add in Morse code is :
.—..-..
There are 8 total symbols, 5 of them are dots.
The fraction would be 5/8 are dots.
Answer:
[tex]\frac{5}{8}[/tex]
Step-by-step explanation:
The Morse Code for Add is:
.__.._..
There are 5 dots and 3 dashes, so there are 8 figures in total. The fraction is 5 divided by the total number of symbols, which is 8. So the answer is [tex]\frac{5}{8}[/tex]
Assume that y varies directly with x. If y = -15 when x = -5, find y when x = 3.
Write and solve a direct variation equation to find the answer.
y=
Answer: Y = 9
Step-by-step explanation:
Y & X
Y = KX
K = Y / X = - 15 / - 5 = 3
X = 3
K= 3
Y=?
Y = KX = 3 x 3 = 9
Therefore, when X = 3, Y = 9
If NS = 2x + 7 and SQ = 5x - 23, find NQ
Incomplete Question Consider here NS = SQ then we may solve for NQ
Answer:
Therefore,
[tex]NQ=54\ units[/tex]
Step-by-step explanation:
Consider N -S -Q as a Straight line as shown in the figure below such that,
[tex]NS = 2x + 7[/tex]
[tex]SQ = 5x -23[/tex]
[tex]NS =SQ[/tex] ..............Consideration
To Find:
NQ = ?
Solution:
[tex]NS =SQ[/tex] .....Given Consideration
Substituting the values we get
[tex]2x+7=5x-23\\\\3x=30\\\\x=\dfrac{30}{3}=10[/tex]
Therefore,
[tex]NS = 2\times 10 + 7 = 27[/tex]
[tex]SQ = 5\times 10 -23=27[/tex]
N -S-Q is a Straight Line,
Then BY Line Addition Postulate,
[tex]NQ=NS+SQ[/tex] ...............N-S-Q
Substituting the values we get
[tex]NQ=27+27=54\ units[/tex]
Therefore,
[tex]NQ=54\ units[/tex]
