Answer:
TR = 24 units
Step-by-step explanation:
Given 2 secants from an external point to a circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and whole of the other secant, that is
3x(3x + 5x) = 8(8 + 19)
3x × 8x = 8 × 27
24x² = 216 ( divide both sides by 24 )
x² = 9 ( take the square root of both sides )
x = ± [tex]\sqrt{9}[/tex] = ± 3
but x > 0, thus x = 3
Thus
TR = 8x = 8 × 3 = 24

Bonnie spent $______on lunch.
Answers
Answer:
the answer is 19.50
Step-by-step explanation:
lets start by by reviewing the problem
bonnie withdrew 1200 dollars
she spend 240 on travel agents
then she spends 640 at the hardware store
so if we add all of that up we get 880
then we will subtract that from the total of her money
=320 left but we aren't finished
then she spend some money on lunch
so we would subtract 320 from
300.50
hence getting

An investment has probabilities 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15 of giving returns equal to 50%,
39%, -4%, 20%, -25%, and 42%. What are the expected returns and the standard deviations of
returns?
Answers
The expected returns is 33.7% and the standard deviations of returns is 38.73%.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Now given probabilities are,
probabilities P = 0.15, 0.34, 0.44, 0.67, 0.2 and 0.15
Given returns on the probabilities,
returns r = 50%, 39%, -4%, 20%, -25%, and 42%
So, Expected rate of returns = ∑Pr
⇒ Expected rate of returns = 0.15(50) + 0.34(39) + 0.44(-4) + 0.67(20) + 0.2(-25) + 0.15(42)
⇒ Expected rate of returns = 7.5 + 13.26 - 1.76 + 13.4 - 5 + 6.3
⇒ Expected rate of returns = 33.7%
Now standard deviation S is,
Square root of the difference squared between each value and the mean, multiplied by the probability.
S = √{0.15(50 - 33.7)² + 0.34(39 - 33.7)² + 0.44(-4 - 33.7)² + 0.67(20 - 33.7)² + 0.2(-25 - 33.7)² + 0.15(42 - 33.7)²}
⇒ S = √{0.15(16.3)² + 0.34(5.3)² + 0.44(-37.7)² + 0.67( - 13.7)² + 0.2(-58.7)² + 0.15(8.3)²}
⇒ S = √{0.15(265.69)+ 0.34(28.09) + 0.44(1421.29) + 0.67( - 187.69) + 0.2(3445.69)²\ + 0.15(68.89)}
⇒ S = √{39.85 + 9.55 + 625.36 + 125.75 + 689.13 + 10.33}
⇒ S = √{1499.97}
⇒ S = 38.73%
Thus, the expected returns is 33.7% and the standard deviations of returns is 38.73%.

The store is selling lemons at $0.66 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies,each requiring half a cup of lemon juice?
Answers
Answer:
$7.92
Step-by-step explanation:
1 lemon = 2 tbsp = $0.66
1 pie = 1/2 cup
So take 3 x 1/2 = 1 1/2 cups. Now we know that we need 1 1/2 cups of lemon juice. So convert 1 1/2 cups into tbsp and you get 24 tbsp. Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2 and you get 12. This 12 represents the amount of lemons you need to buy. Since 1 lemon is $0.66 take that and multiply it by the amount of lemons you need (12x0.66) now you get $7.92.
You need $7.92 to but 12 lemons to make three 9 inch lemon pies.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
1 cup of lemon juice requires around 16 tablespoons of of juice.
1 lemon = 2 tbsp = $0.66
1 pie = 1/2 cup
number of cups = 3 x 1/2 = 1 1/2 cups.
Now we know that we need 1 1/2 cups of lemon juice. convert 1 1/2 cups into tablespoons and you get 24 tablespoons .
Now since 1 lemon is equal to 2 tbsp divide the 24 tbsp by 2
number of tablespoons = 24/2 = 12.
This represents the amount of lemons you need to buy.
Since 1 lemon is $0.66 take that and multiply it by the amount of lemons number of lemons = (12x0.66) = $7.92.
WE need $7.92 to but 12 lemons to make three 9 inch lemon pies.

The first three terms of an arithmetic sequence are as follows 9,4,-1 find the next two terms
Answers
The following two terms of an arithmetic progression are -6 and -11.
What is an arithmetic sequence?
An arithmetic sequence is defined as a progression of numbers such that the difference between successive terms is consistent. It is also called Arithmetic Progression. The formula for tthe last term of an AP is given as: an = a + (n-1)d, here, a is the first term, n is the number of terms and d is the difference between two successive terms.
Finding the two terms of an arithmetic sequence
The first three terms of an arithmetic sequence are given by:
a1 = 9
a2 = 4
a3 = -1
Now, we want to calculate a4 and a5
Using the formula for calculating the next term of an arithmetic progression, we get,
a4 = a + (n-1)d, where n = 4 and d = 5
a4 = 9 + (4-1)(-5)
a4 = 9 - 15
a4 = -6
Further, a5 = a + (n-1)d, where n = 5 and d = 5
a5 = 9 + (5-1)(-5)
a5 = 9 - 20
a5 = -11
Hence, the next two terms of an AP are -6 and -11.

Answers
Answer:
12%
Step-by-step explanation:
Add each number of students in the graph together. 1 + 6 + 2 + 3 = 12, so it's 12%.
Percentage of students who responded to the survey is 48 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The total number of students in the survey = 25 students
The number of students who played Violin = 1 student
The number of students who played Piano = 6 students
The number of students who played Guitar = 2 students
The number of students who played Drums = 3 students
So ,
Total number of students who played instruments =
Number of students who played Violin + Number of students who played Piano + Number of students who played Guitar + Number of students who played Drums
Total number of students who played instruments = ( 1 + 6 + 2 + 3 )
= 12 students
Now ,
Percentage of students who played the instruments = Percentage of students who responded to the survey
And ,
Percentage of students who responded to the survey =
( Total number of students who played instruments / Total number of students in the survey ) x 100
Percentage of students who responded to the survey = ( 12 / 25 ) x 100
= 12 x 4
= 48 %
Therefore , percentage of students who responded to the survey = 48 %
Hence , percentage of students who responded to the survey is 48 %

What is inequality?Inequality is a relation that makes a non-equal comparison between two expressions.
Batting average of William = 11/53
Desired batting average = 0.300
Suppose the number of more hits in a row to have desired batting average =x
Number of hits now =11+x
Number of bats now =53+x
It is given that the batting average should be a minimum of 0.300.
This means [tex]\frac{11+x}{53+x} \leq 0.300[/tex]
Therefore, the equation that could be used to determine x is [tex]\frac{11+x}{53+x} \leq 0.300[/tex].
