Answer: 4
Step-by-step explanation:
Given
PA=6, PD=4, BE=5
We know, If PEB is a secant that intersects the circle at E and B and PA be a tangent at A, then
[tex]PA^2=PE\cdot PB[/tex]
Substitute the given values
[tex]\Rightarrow 6^2=(PE+BE)\cdot(PE)\\\Rightarrow 36=(PE+5)\cdot(PE)[/tex]
Take [tex]PE=x[/tex]
[tex]\Rightarrow 36=x^2+5x\\\Rightarrow x^2+5x-36=0\\\Rightarrow x^2+9x-5x-36=0\\\Rightarrow (x+9)(x-4)=0\\\Rightarrow x=-9,4[/tex]
Discard [tex]x=-9[/tex]
[tex]\therefore PE=4[/tex]

Step-by-step explanation:
The area of a square is
[tex] {s}^{2} [/tex]
where s is the side length.
It is given that the smaller square side length is s so that means the area of that smaller square is the formula above.
The longer square is twice the side length of the side length of the smaller square.
Since all squares have equal sides, that means all the side are twice than the smaller square sides.
We can represent that larger square area by
(4s) squared
To find how many smaller squares it would take to fill the larger square divide the formula by each other.
(4s)÷s squared =4

Answer: 25%
Step-by-step explanation:
STEP ONE: Find the total possible ways to roll the dice.
- Each roll has 6 possible numbers
- Each roll is independent
6×6=36 possible combination
STEP TWO: Find the possible ways to roll the dice in odd-odd
- Each roll has 3 odd number (1, 3, 5)
- Each roll is independent
3×3=9 possible combination
STEP THREE: Put it into a fraction
Possibility of odd-odd=(possible odd-odd combination)/(total combination)×100%= 9/36 × 100%=0.25 × 100%= 25%

Area of Compound ShapesThis question requires your knowledge about the area of compound shapes. For solving this, you should:
Identify the basic shapes;Calculate your individual areas; Sum each area found. STEP 1 - Identify the basic shapes.The figure is composed of:
two squares whose sides are equal to 3 in. 1 rectangle whose sides are: 9 in and 3 inTherefore, you should sum the area of these geometric figures for determining the given area.
STEP 2 - Find the area of the squares.Area of each square = a², where a=the length of the side.
Like, the length of the side is equal to 3 in, the area will be:
A_square= 3²=9 in².
You have two squares in the figure. Then, the total area for the squares is 9 + 9 =18 in²
STEP 3 - Find the area of the rectangle.
Area of the rectangle = bh . The figure shows that: the base = 9 in and the 3=8 in
Thus, A_rectangle=bh= 9*3=27in²
STEP 4 - Find an expression for the total area of the figure.
A_total= A_squares+ A_rectangle
A_total= 18+27=45 in²
A_total= 45in²

For the following, indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest. A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.
The goal of the research was to estimate the amount of time it typically takes to complete a round of golf on Saturday morning. The confidence interval for a population _____________ proportion mean should be constructed because the variable of interest is _________ score, time to complete the round, whether the round was completed in less than 5 hours or not, which is a ___________ qualitative quantitative variable.
Answer:
The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.
Step-by-step explanation:
A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.
Time is the number of hours, so it is mean, and not proportion.
Variable of interest is time to complete the round, and since it is measured in hours it is a quantitative variable.
The answer is:
The confidence interval for a population mean proportion mean should be constructed because the variable of interest is time to complete the round, which is a quantitative variable.
The confidence interval for a population of variable of interest time is normally distributed . The Confidence interval for proportion mean should be constructed because the variable of interest is the time taken to complete one round of golf score, time to complete the round.
Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables of the sample taken which is a quantitative variable.
The confidence interval for the normally distributed variable of interest is determined by the equation as formulated below
[tex]\rm Confidence\; Interval = \mu - Z \sigma/\sqrt{n} \;\;to \; \mu + Z \sigma/\sqrt{n} \\Where\\\mu = Sample\; mean \\Z = Z \; score \\\\\sigma = Sample\; standard \; deviation \\n = Sample \; size[/tex]
We have to indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest.
A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round.
The goal of the research was to estimate the amount of time it typically takes to complete a round of golf on Saturday morning
As given by the language of the question we can conclude that the variable of interest is the time taken to complete one round of golf.
So we consider that the time variable is normally distributed
Also time variable is quantitative variable.
So we can fill in the blanks
The confidence interval for a population of variable of interest time is normally distributed .The Confidence interval for proportion mean should be constructed because the variable of interest is the time taken to complete one round of golf score, time to complete the round.
Whether the round was completed in less than 5 hours or not is depending upon the calculations involved and variables of the sample taken which is a quantitative variable.

Answer:
(d) is true
Explanation:
Given
[tex]Brown = 8[/tex]
[tex]Purple = 7[/tex]
Required
Which of the options is true
A) P(Brown) = P(Not Brown)
P(Brown) is calculated as:
[tex]P(Brown)=\frac{Brown}{Brown + Purple}[/tex]
[tex]P(Brown)=\frac{8}{8+7}[/tex]
[tex]P(Brown)=\frac{8}{15}[/tex]
P(Not Brown) is calculated as:
[tex]P(Not\ Brown) = 1 - P(Brown)[/tex] --- Complement rule
[tex]P(Not\ Brown) = 1 - \frac{8}{15}[/tex]
Solve
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
Both are not equal.
Hence, (a) is not true
(b) P(Brown) < P(Not Brown)
In (a) above
[tex]P(Brown)=\frac{8}{15}[/tex]
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
By comparison;
[tex]P(Brown) > P(Not\ Brown)[/tex]
Because:
[tex]8/15 > 7/15[/tex]
Hence, (b) is not true
(c) P(Not Brown) > P(Brown)
This is the same as (b)
i.e. both conditions represent the same.
Hence, (c) is incorrect
(d) P(Brown) > P(Not Brown)
In (b), we established that
[tex]P(Brown) > P(Not\ Brown)[/tex]
Because:
[tex]P(Brown)=\frac{8}{15}[/tex]
[tex]P(Not\ Brown) = \frac{7}{15}[/tex]
[tex]8/15 > 7/15[/tex]
Hence, (d) is true

Reduce 65 in ratio 5:2
Answer: [tex]46.42:18.57[/tex]
Step-by-step explanation:
[tex]5+2 = 765/7 × 5 = 46.4265/7 × 2 = 18.57∴ 65 in the ratio 5:2 = 46.42:18.57x^{2}[/tex]
The solution is 46.42857 : 18.57143
The proportion equation is given by 46.42857 : 18.57143 and
46.42857 + 18.5714365 = 65
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number be represented as N
The value of N = 65
The proportion is 5 : 2
The total value of the ratio = 5 + 2 = 7
So , each value of the proportion is x = 65 / 7
On simplifying the equation , we get
Each value of the proportion is x = 9.2857142857
Now , the proportion equation is given by
The value of 5x = 5 ( 9.2857142857 )
The value of 5x = 46.42857
The value of 2x = 2 ( 9.2857142857 )
The value of 2x = 18.57143
And , 46.42857 + 18.5714365 = 65
Hence , the proportion is 46.42857 : 18.57143 or 5 : 2
