Answer
$200,000
Step-by-step explanation:
She invested $100,000
5% of $100,000 is $5,000.
After 20 years, (5,000 X 20 years) = $100,000
Starting balance of $100,000 + $100,000 = $200,000
The total amount in 20% with simple interest for over 20 years will be $200,00.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant.
As per the given,
Principle amount P =$100000
Rate of interest R = 5%
Time period T = 20 years
Total amount = Principal amount + interest
Total amount = P + PRT/100
Total amount = 100000 + (100000 x 5 x 20)/100
Total amount = $200,000
Hence "The total amount in 20% with simple interest for over 20 years will be $200,00".

Human visual inspection of solder joints on printed circuit boards can be very subjective. Part of the problem stems from the numerous types of solder defects (e.g., pad non-wetting, knee visibility, voids) and even the degree to which a joint possesses one or more of these defects. Consequently, even highly trained inspectors can disagree on the disposition of a particular joint. In one batch of 10,000 joints, inspector A found742that were judged defective, inspector B found745such joints, and1145of the joints were judged defective by at least one of the inspectors. Suppose that one of the 10,000 joints is randomly selected.
(a) What is the probability that the selected joint was judged to be defective by neither of the two inspectors? (Enter your answer to four decimal places.)
(b) What is the probability that the selected joint was judged to be defective by inspector B but not by inspector A? (Enter your answer to four decimal places.)
Answer:
a
The probability that the selected joint was judged to be defective by neither of the two inspectors is [tex]P(A' n B' ) = 0.8855[/tex]
b
The probability that the selected joint was judged to be defective by inspector B but not by inspector A is [tex]P(A' n B) =0.0403[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n_s = 10000[/tex]
The number of outcome for inspector A is [tex]n__{A}} = 742[/tex]
The number of outcome for inspector B is [tex]n__{B}} = 745[/tex]
The number of joints judged defective by both inspector is [tex]n(A u B) = 1145[/tex]
The the probability that the selected joint was judged to be defective by neither of the two inspectors is mathematically represented as
[tex]P(A' n B' ) = 1 - P(A u B)[/tex]
Now
[tex]P(A\ u \ B) = \frac{n(Au B)}{n_s }[/tex]
substituting values
[tex]P(A\ u \ B) = \frac{1145}{ 10 000 }[/tex]
So
[tex]P(A' n B' ) = 1 - \frac{1145}{10 000}[/tex]
[tex]P(A' n B' ) = 0.8855[/tex]
the probability that the selected joint was judged to be defective by inspector B but not by inspector A is mathematically represented as
[tex]P(A' n B) = P(A \ u \ B) -P(A)[/tex]
Now
[tex]P(A) = \frac{n__{A}}{n_s}[/tex]
substituting values
[tex]P(A) = \frac{742}{10 000}[/tex]
So
[tex]P(A' n B) = \frac{1145}{10 000} - \frac{742}{10 000}[/tex]
[tex]P(A' n B) =0.0403[/tex]
What is the surface area of the rectangular pyramid? m2 18 point for how ever awncers this first
Answer:
When all side faces are same
surface area = lw + 1/2 × perimeter × slant height.
When the side faces are different
surface area = base area + lateral area
Step-by-step explanation:
The question you ask is the formula one can use to calculate the surface area of a rectangular pyramid.
The base of a rectangular pyramid is rectangular. The picture below shows how a rectangular pyramid looks like .
The surface area of the rectangular pyramid includes the area of the base and areas of all the triangular faces. This simply implies the area of the rectangular base and the area of each triangular faces. Mathematically, it can be represented below.
The base area(rectangle) = length × width = lw
Area of a triangle = 1/2 × base × height = 1/2bh
Therefore, if all the faces of the triangle are the same(regular pyramid) the total surface area will be
surface area = lw + 1/2 × perimeter × slant height.
Note the triangular faces are 4 in numbers.
If all the sides of the triangle are different the surface are will be
surface area = base area + lateral area
We have to add the triangular faces individually for an irregular pyramid.

What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Given that;
A man travelled 450 km on the first day and 565,000 m on the second day, the third day he travel double the distance you travel on the first day.
Here, On the fourth day he reached his destination which was 2500km from his starting point.
Let the distance he travel on the fourth day = x
So, We can formulate;
⇒ 450 km + 565,000 m + 2 × 450 km + x = 2500 km
⇒ 450 km + 565 km + 900 km + x = 2500 km
⇒ 1915 km + x = 2500 km
⇒ x = 2500 - 1915
⇒ x = 585 km

Florida reappraises real estate every year, so the county appraiser's Web site lists the current "fair market value" of each piece of property. Property usually sells for somewhat more than the appraised market value. Here are the appraised market values and actual selling prices (in thousands of dollars) of condominium units sold in a beachfront building in a 93-month period:
Selling price 832 878 628 1067 924 792 645 854
Appraisal value 744.7 842.8 480.9 1005.2 787.9 758.3 548.9 634.3
Selling price 764 708 752 862 720 1099 1301 800
Appraisal value 641.7 514.8 552.9 747.4 475.5 756.3 1039.4 582.8
Here is part of the Minitab output for regressing selling price on appraised value:
Predictor Coef SE Coef T
Constant 227.0989 95.044 2.389
Appraisal 0.8991 0.133 6.76

The equation of the least square regression line for predicting selling price from appraised value is (round your answer to at least four decimals):
price appraised value.
Answer:
The equation of the least square regression line for predicting selling price from appraised value is:
[tex]\text{Selling Price}=227.0989 + 0.8991\ \text{Appraised Value}[/tex]
Step-by-step explanation:
The general form of the least square regression line is:
[tex]y=a+bx[/tex]
Here,
y = dependent variable
x = independent variable
a = y-intercept
b = slope
The Minitab output for regressing selling price on appraised value is:
Predictor Coef SE Coef T
Constant 227.0989 95.044 2.389
Appraisal 0.8991 0.133 6.76
S = 88.7959
R-Sq = 76.5%
R-Sq (adj) = 74.9%
The constant term in the regression output represents the y-intercept and the Appraisal coefficient the slope of the regression line.
Then the equation of the least square regression line for predicting selling price from appraised value is:
[tex]\text{Selling Price}=227.0989 + 0.8991\ \text{Appraised Value}[/tex]
Given y = 4x + 3, what effect does changing the equation to y = 4x - 3 have on the y-intercept?
A)
graph becomes steeper
B)
no change to y-intercept
C)
graph moves down 3 units
D)
graph moves down 6 units
Answer:
graph moves down 6 units
Step-by-step explanation:
Y intercept of a line is point on y axis where the line crosses the y-axis.
Since the line is of the slope intercept form y = mx+ c
where m is slope of line and c is y intercept
_________________________________________________
Equation of old line : y = 4x + 3
then for equation y = 4x + 3
m: 4 and c = 3
Thus y intercept is +3 unit above the X axis
_________________________________________________
Equation of new line : y = 4x - 3
Similarly based on above explanation
m: 4 and c = -3
Thus y intercept is +3 unit below the X axis.
Thus we can see that y intercept has moved downward
Lets calculate no. of units it moved downward
Distance between them is 3 - (-3) = 6 unit
Thus graph moved 6 units downwards.
Steepness of graph depends on slope of line. The slope is 4 for both the lines and hence there is no change in steepness.
Thus correct answer is graph moves down 6 units

bo and Luke are driving to uncle Jesse's house their car at the generally can go nearly 208 miles on 13 gallons of gas they only have 3 gallons of gas left in the tank but they are 42 miles away from uncle Jesse's house how far can the generally go on 3 gallons of gas in its tank
Answer:
48 miles
Step-by-step explanation:
What we must do is calculate the car's performance, that is, the number of miles per gallon of gas, like this:
208/13 = 16
which means that for each gallon of gas you can travel a total of 16 miles.
They tell us they have 3 gallons of gasoline left so they can go:
16 * 3 = 48
If your goal is 42 miles away, that means you can make it and you still have 6 more miles to go.
Find the value of x in the
following parallelogram:
2x - 10
2x + 50
Answer:
the value of x = 35 ( NOT - 40 )
Step-by-step explanation:
In order to calculate the value of x in the following parallelogram: 2x - 10
2x + 50, we would have to calculate the following formula:
m<QPS+m<PQR=180°
According to the given data we have the following:
m<QPS=2x - 10
m<PQR=2x + 50
Therefore, 2x - 10+2x + 50=180
4x+40=180
x=140/4
x=35
The value of x is 35 because in a parallelogram sum of the two adjacent angles is equal to 180 degree
What is parallelogram?In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
As we know,
In a parallelogram sum of the two adjacent angles is equal to 180 degree
2x - 10 + 2x + 50 = 180
4x + 40 = 180
4x = 140
x = 35
Thus, the value of x is 35 because in a parallelogram sum of the two adjacent angles is equal to 180 degree

If b (middle term) is negative and c (last term is positive) then what do you know about the two factors? ex. 2x^2-7x+6
Answer:
signs of the constants in the binomial factors are negative
Step-by-step explanation:
Assuming the first term (a) is positive, the fact that c is negative means the constants in the binomial factors have the same sign. The negative b means that sign is negative.
2x^2 -7x +6 = (x -2)(2x -3)
__
Further comment
c is the product of the constants in the binomial factors so will be positive when both those constants have the same sign.
b is the sum of the constants in the binomial factors. If both factors have the same sign (c > 0), then those constants have the same sign as b.
In this analysis, "a" is assumed to be positive. If it is not, then the same analysis can be done after reversing all of the signs.

What is the measure of the whole angle?
Answer:
130
Step-by-step explanation:
60° + 70° = x
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 60 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
60 + 70 = x
→ Simplify
130 = x
x = 130°
