Lizzie invested $2,000 into an account that earned 5% interest per year. When she
cashed out the investment, it was worth a total of $2,205.
Create an equation (using the word bank) that describes Lizzie's investment based on t,
the number of years she kept the account open.
Word Bank:
1.05
0.05
$2.205
$205
t
$2,000
Step-by-step explanation:
The way to approach the problem is this
After one year she has 2000*1.05
After two years she has the money from the last year plus interest, so she has 2000*1.05*1.05
After t years she has 2000*1.05

5x - (6 - x)
Answer:
6x-6
Step-by-step explanation:
5x-(6-x)
First you distribute the negative to (6-x) which makes -6+x, then you just subtract that from 5x which makes 5x-6+x then you just simplify into 6x-6.

Twenty distinct cars park in the same parking lot every day. Ten of these cars are USmade while the other ten are foreign-made. The parking lot has exactly twenty spaces all in a row so the cars park side by side. However, the drivers have varying schedules so the position any car might take on a certain day is random. What is the probability that on a given day, the cars will park in such a way that they alternate (i.e., no two US-made cars are adjacent and no two foreign-made cars are adjacent)?
Answer:
The probability that on a given day, the cars will park in such a way that they alternate is 1.0825 × 10⁻⁵.
Step-by-step explanation:
It is provided that the cars will be parked in such a way that they will be alternating: US made, foreign made, US made, foreign made, etc.
First park all the US cars. This can be done in 10! ways, since the cars are distinct.
Now park the foreign cars between the US cars. This can also be done in 10! ways.
Since the sequence could begin either with a US car or with a foreign car, the possible number of ways to park alternating cars is
Favorable Outcomes = 2 × 10! × 10!
The total number of ways to park the 20 distinct cars is,
Total Outcomes = 20!
Compute the probability that on a given day, the cars will park in such a way that they alternate as follows:
[tex]P(\text{Alternate Parking})=\frac{\text{Favorable Outcomes}}{\text{Total Outcomes}}[/tex]
[tex]=\frac{2\times 10!\times 10!}{20!}\\\\=\frac{2\times 10!\times 10!}{20\times 19\times 18\times ...10!}\\\\=\frac{2\times 10!}{20\times 19\times 18\times ...11}\\\\=1.0825\times 10^{-5}[/tex]
Thus, the probability that on a given day, the cars will park in such a way that they alternate is 1.0825 × 10⁻⁵.

Round to the place valué of the under lined digit 641,267 the 4 Is under lined
answer:
640,000
step-by-step explanation:
to find the answer, we need to determine whether 41,267 is closer to 40,000 or 50,000.
looking at the numberline, we can conclude that the placement of 641,267 is closer to 640,000, not 650,000.
therefore, the answer is 640,000. (see image attached)

Answer:
(a) 6 °C
(b) -3.7 °C
(c) the y-intercept is (0, 10); the x-intercept is (10, 0)
Step-by-step explanation:
(a) The graph tells you the wind chill is 6 °C when the wind speed is 4 m/s.
__
(b) The annotated point on the graph tells you the wind chill is -3.7 °C when the wind speed is 20 m/s.
__
(c) The intercepts are marked on the graph. The y-intercept is (0, 10); the x-intercept is (10, 0). These represent the temperature when the wind speed is 0, and the wind speed when the temperature is 0, respectively.
PLS HELP! which graph is the function 3x + 2y = 8 with the given domain {-2,0,2,4}??
Answer:
D
Step-by-step explanation:
Domain of the function 3x + 2y = 8 are the possible set of x-values represented as {-2, 0, 2, 4}.
To know which graph represents the above given function, find the range values of the function by plugging in each value of x into the equation, to find y.
For x = -2,
3(-2) + 2y = 8
-6 + 2y = 8
2y = 8 + 6
2y = 14
y = 14/2
y = 7
(-2, 7)
For x = 0,
3(0) + 2y = 8
0 + 2y = 8
2y = 8
y = 8/2
y = 4
(0, 4)
For x = 2,
3(2) + 2y = 8
6 + 2y = 8
2y = 8 - 6
2y = 2
y = 2/2
y = 1
(2, 1)
For x = 4,
3(4) + 2y = 8
12 + 2y = 8
2y = 8 - 12
2y = -4
y = -4/2
y = -2
(4, -2)
The graph which shows the following set of coordinates pairs calculated above, ((-2, 7), (0, 4), (2, 1), (4, -2)), is the graph of the function 3x + 2y = 8.
Thus, the graph in option D the shows the following calculated coordinate pairs. Therefore, graph D is the answer.

Find the equation of the line using the given information.
(x, y) = (-3,0) and (x, y) = (-3, 5) are points on the line
Pls help
Answer:
x 1 = -3
x2 = -3
y1 = 0
y2 = 5
The slope of that equation is infinite and the equation is a perfectly vertical line at x = -3.
So, the equation is x = -3.
Step-by-step explanation:
Given parameters:
The coordinates of points on the line;
(x, y) = (-3,0) and (x, y) = (-3, 5)
Unknown;
The equation of the line = ?
The equation of a line is usually expressed in the form y = mx + c
Where;
y and x are the coordinates
m is the slope
c is the y-intercept
Now we need to first find the slope of the line.
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
(x₁, y₁) = (-3,0) and (x₂, y₂) = (-3, 5)
Input the parameters and solve;
Slope = [tex]\frac{5 - 0}{-3 -(-3)}[/tex] = infinity
The line has an infinite slope.
The equation of the line is therefore x = c
x = -3
Work out the percentage change when 1.20 is increased to 1.80
Answer:
Step-by-step explanation:
PERCENT CHANGE
The percentage change from 1.20 to 1.80 is 50 %
Our percent calculator uses this formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((1.80 - 1.20) / 1.20) * 100 = 50 %
The run times of a marathon runner are approximately normally distributed. The z-score for his run this week is – 2 . Which one of the following statements is a correct interpretation of his z-score?
Answer:
2 standard deviation under his average time
Step-by-step explanation:
Without using a calculator, order the following expressions from least to greatest.
Here we want to order from least to greatest the following expressions:
7.12 = 7.121212...
√75
√45
We will find that the order is: √45 < 7.12 < √75
remember that:
√x = y
such that:
y*y = x
From this, is easy to see that:
√45 < √75
Now to see where 7.1212... enters, we need to compute:
(7.1212...)*(7.1212...) = (7 + 0.1212...)*(7 + 0.1212...)
= 7*7 + 2*7*0.121212... + 0.1212...*0.1212...
= 49 + 2*7*0.121212... + 0.1212...*0.1212... > 45
So we know for sure that:
7.12 > √45
And 8*8 = 64 < 75
then:
7.12 < 8 = √64 < √75
For transitivity, we have:
7.12< √75
Then the order, from least to greatest, is:
√45 < 7.12 < √75

Write the equation of the line fully simplified slope-intercept form.
HELP ME PLEASE
Answer:
y=-x+3
Step-by-step explanation:
The y-intercept is at 3 and you can see it has a slope of -1
The equation of line will be y = -x + 3.
It is given that in the graph, line is passing through some points at x-axis and y-axis.
We have to find the fully simplified intercept of the line.
What is the general equation of a line ?
The equation of a line is y = mx + c , where m is the slope of the line and c is a constant.
We have the x-intercept (3,0) and y-intercept (0,3) on the graph.
Slope of these line through these points will be ;
m = (y2-y1) / (x2-x1)
m= (3-0) / (0-3)
m= 3/-3
m= -1
Also , we will get the value of c = 3 .
The equation of line after putting the value of m and c will be ,
y = -x + 3
Thus, the equation of line is y = -x + 3

Joel used a half gallon of paint to cover 84 square feet of wall. He has 932 square feet of wall to paint. How many gallons of paint should he purchase?
I will give u a Brainly <33 :)
Answer:
6 Gallons of Paint
Step-by-step explanation:
If you use a half gallon of paint to cover 84 square feet, how much could you paint with a full gallon? Lets figure it out:
[tex]\frac{1}{2} = 84[/tex]
multiply both sides by 2 so that the 1/2 gallon is now 1 gallon:
[tex]\frac{1}{2} * 2 = 84 * 2[/tex]
1 gallon = 168 square feet
now, how many gallons does it take to paint 932 square feet?
Divide 932 by 168:
[tex]\frac{932}{168} = 5.548[/tex]
Just like you cant buy 2.374 cheeseburgers, you cant buy 5.548 gallons of something so we round up and will have some paint left over once the job is done. So 6 gallons is the answer
The amount of gallons needed is 5.55gallons approximately
If Joel used a half-gallon of paint to cover 84 square feet of wall, this can be expressed using the equality sign as:
1/2 gallons = 84 square feet
In order to find the number of gallons for 932 square feet of wall to paint, we will write:
x = 932 square feet
Divide both expressions
1/2x = 84/932
2x = 932/84
2x = 11.09
x = 11.09/2
x = 5.55 gallons
This shows that the amount of gallons needed is 5.55gallons approximately
