Last year the chess club had 20 members. This year the club has 15 members. Find the percentage of change and state whether the percent of change is an increase or decrease
The negative sign indicates a decrease in the number of members. Therefore, the percentage change of -25% means that the number of members decreased by 25%. To summarize, the percentage change in the number of members from last year to this year is 25% decrease.
To find the percentage change in the number of members from last year to this year, we'll use the formula for percentage change:
[tex]\[ \text{Percentage change} = \left( \frac{\text{New value} - \text{Old value}}{\text{Old value}} \right) \times 100\% \][/tex]
Given that last year the chess club had 20 members and this year it has 15 members, we can plug these values into the formula:
[tex]\[ \text{Percentage change} = \left( \frac{15 - 20}{20} \right) \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = \left( \frac{-5}{20} \right) \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = -\frac{1}{4} \times 100\% \][/tex]
[tex]\[ \text{Percentage change} = -25\% \][/tex]
The negative sign indicates a decrease in the number of members. Therefore, the percentage change of -25% means that the number of members decreased by 25%.
To summarize, the percentage change in the number of members from last year to this year is 25% decrease.
The complete question is:
Last year the chess club had 20 members. This year the club has 15 members. Find the percentage of change and state whether the percent of change is an increase or decrease.

The formula for finding the present value of an item that depreciates yearly is v = c - crt. In this formula, v is the present value, c is the original cost, r is the rate of depreciation per year, and t is the number of years that have passed. After 7 years, what is the value of a car originally costing $27,000 that depreciated at a rate of 0.1 per year
Final answer:
To calculate the present value of a car after 7 years, using the formula v = c - crt with the given values, the present value is $8,100.
Explanation:
The question involves finding the present value of a depreciating asset, in this case, a car. Using the provided formula v = c - crt where v is the present value, c is the original cost, r is the rate of depreciation per year, and t is the number of years, we can calculate the value of a car after a certain time period.
Given that the original cost c is $27,000, the rate of depreciation r is 0.1 (or 10%), and the time t is 7 years, we can substitute these values into the formula to find the present value of the car after 7 years. The calculation is as follows: v = $27,000 - ($27,000 × 0.1 × 7). Simplifying, we get: v = $27,000 - ($27,000 × 0.7) = $27,000 - $18,900 = $8,100.

What is 1/x divided by 1/y equal to ?
Final answer:
To calculate 1/x divided by 1/y, you multiply 1/x by the reciprocal of 1/y, which is y, resulting in y/x.
Explanation:
The question asks us to find the value of 1/x divided by 1/y. This is a division problem involving fractions and can be solved using the rules of division for fractions.
To divide one fraction by another, we multiply the first fraction by the reciprocal of the second. In this case, the reciprocal of 1/y is y/1 which simplifies to y. Therefore, the division 1/x ÷ 1/y becomes 1/x × y.
When we multiply these together, we get:
So, the answer is y/x.

Calculate the median of the data set below. {3, 7, 9, 2, 5, 3, 4, 6, 1, 0} A. 3 B. 3.5 C. 4 D. 10
Answer:
The median of the data set is 3.5 ⇒ answer (B)
Step-by-step explanation:
* Lats talk about the median of the data
- The median is the middle value of the arranged data
- You must to arrange the data at first to find the median
- The number of data is very important when you find the median
- If the number of data odd (1 , 3 , 5 , 7 , .....), then the median
will be the middle one of the data
* Ex: if the number of data is 13, then the median will be the 7th on
∵ 13 ÷ 2 = 6.5, then there are 6 numbers before and 6 number after
∴ The median is the 7th one
- If the number of data even (2 , 4 , 6 , 8 , .....), then there is no
middle on, we will find two numbers on the middle.
So we take the average of them
* Ex: if the number of data is 12, then the median will be the
average of the 6th and 7th numbers
* Lets use this conditions in our problem
- The data are 3 , 7 , 9 , 2 , 5 , 3 , 4 , 6 , 1 , 0
- At first arrange the data
* 0 , 1 , 2 , 3 , 3 , 4 , 5 , 6 , 7 , 9
- The number of data is 10
∵ 10 ÷ 2 = 5
∴ The median will be the average of the 5th and 6th numbers
∵ The 5th number is 3 and the 6th number is 4
∴ The median = (3 + 4)/2 = 3.5
* The median of the data set is 3.5

A farmer has 60 bales of hay stored in his barn. He feeds his cows 4 bales each day. Which graph represents the number of bales in the barn, y, after feeding his cows for x days?
Answer:
The required equation is [tex]y=-4x+60[/tex] and graph of this equation is shown below.
Step-by-step explanation:
Let y be the number of bales in the barn after feeding his cows for x days.
It is given that a farmer has 60 bales of hay stored in his barn.
Initial number of bales = 60
He feeds his cows 4 bales each day. It means number of bales decrease by 4 bales per day.
Slope = -4
The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
Substitute m=-4 and b=60 in the above equation.
[tex]y=-4x+60[/tex]
The y-intercept of the graph is 60.
The table of values is shown below
x y
0 60
15 0
Plot these these points on coordinate plane and connect them by a straight line.
The required graph is shown below.
A line of best fit predicts that when x equals 25, y will equal 27.745, but y actually equals 29. What is the residual in this case? A. 1.255 B. -1.255 C. -2.745 D. 2.745
Answer:
The correct option is A.
Step-by-step explanation:
From the given information it is clear that at x=25, the predicted value of y is 27.745 and the actually value is 29.
Predicted value = 27.745
Observed value = 29
The formula for residual is
Residual = Observed value - predicted value
[tex]Residual=y-\hat{y}[/tex]
[tex]Residual=29-27.745[/tex]
[tex]Residual=1.255[/tex]
The residual in this case is 1.255, therefore option A is correct.
The residual is 1.255.
Explanation:The residual is the difference between the actual y-value and the predicted y-value for a given x-value. In this case, the predicted y-value when x equals 25 is 27.745, but the actual y-value is 29. Therefore, the residual is calculated by subtracting the predicted value from the actual value: 29 - 27.745 = 1.255. So, the answer is A. 1.255.

If $7300 is invested in a savings account for which interest is compounded monthly, and if the $7300 turns into $8600 in 2 years, what is the interest rate of the savings account?
Answer:
8.22%
Step-by-step explanation:
The interest rate of the savings account is 8.22%
What is compound interest formula?[tex]A= P(1+\frac{r}{n} )^{nt}[/tex]
where, A : Amount
P = Principal amount
r = Annual interest rate as a decimal
R = Annual interest rate as a percent
r = R/100
n = number of compounding periods per unit of time
t = time in decimal years
What is the formula to find the interest rate?[tex]r=n[(\frac{A}{P} )^{\frac{1}{nt} }-1][/tex]
For given question,
the principal amount (P) = $7300
the amount (A) = $8600
period (t) = 2
n = 12 (since it's monthly compounding)
To find 'r'
Using the formula of rate of interest,
[tex]\Rightarrow r=n[(\frac{A}{P} )^{\frac{1}{nt} }-1]\\\\\Rightarrow r=12\times [(\frac{8600}{7300} )^{\frac{1}{12\times 2} }-1]\\\\\Rightarrow r=12\times [(1.18)^{\frac{1}{24} }-1]\\\\\Rightarrow \bold{r=0.0822}[/tex]
The rate of interest in percentage form,
[tex]\Rightarrow R=r\times 100\\\\\Rightarrow R=0.0822\times 100\\\\\Rightarrow \bold{R=8.22\%}[/tex]
Therefore, the interest rate of the savings account is 8.22%

The diagram below shows a process in earths crust which of the following statements best describes the process in the diagram
The layer with a plastic nature is the mantle (Layer C). The rocks in the mantle can deform and flow over long periods due to heat and pressure, giving them a plastic-like quality. This deformation is crucial for the movement of tectonic plates and various geological processes on Earth.
The Earth is composed of several layers, each with distinct properties and compositions. Starting from the center and moving outward, the major layers are:
Inner Core (Layer A):
The innermost layer is solid and composed mainly of iron and nickel. It is extremely hot, with temperatures reaching up to 9,000 degrees Fahrenheit (5,000 degrees Celsius). Despite the high temperature, the inner core remains solid due to intense pressure.
Outer Core (Layer B):
Surrounding the inner core is the outer core, which is also composed of molten iron and nickel. However, in the outer core, these materials are in a liquid state. The movement of the molten metal in this layer generates the Earth's magnetic field through the geodynamo process.
Mantle (Layer C):
Above the outer core is the mantle, a thick layer of solid rock that can flow slowly over geological timescales. The mantle is mostly composed of silicate minerals rich in iron and magnesium. The convection currents in the mantle are responsible for the movement of tectonic plates.
Crust (Layer D):
The outermost layer is the Earth's crust, which is relatively thin compared to the other layers. The crust is composed of solid rock and is divided into two types: the continental crust (found beneath continents) and the oceanic crust (found beneath oceans). The crust is where we find the solid ground we walk on.

There is a 20% probability that a person inoculated with a particular vaccine will get the disease anyway. a county health office inoculates 83 people. What is the probabythat exactly 10 of them will get the disease at some point their lives?
Answer: 0.021
Step-by-step explanation:
Given : The probability that a person inoculated with a particular vaccine will get the disease anyway. : p= 20%=0.20
The total people inoculates : n= 83
The binomial probability formula :-
[tex]P(X)=^nC_xp^x(1-p)^{n-x}[/tex]
Now, the probability that exactly 10 of them will get the disease at some point their lives :-
[tex]P(X)=^{83}C_{10}(0.2)^{10}(0.8)^{73}\\\\=\dfrac{83!}{10!(83-10)!}(0.2)^{10}(0.8)^{73}=0.0209841759622\approx0.021[/tex]

bernie and chloe hiked the tremont trail 3 1/2 miles to the end and back then they hiked the wildflower trail 2 3/8 miles how far did they hike
Final answer:
Bernie and Chloe hiked a total of 9 3/8 miles after completing the round trip on Tremont Trail and the Wildflower Trail.
Explanation:
Bernie and Chloe hiked the Tremont Trail which was 3 1/2 miles to the end and back, meaning they hiked 7 miles on this trail (since they had to return). After that, they hiked the Wildflower Trail, which was 2 3/8 miles long. To find out the total distance they hiked, you would add these two distances together.
The total distance for the Tremont Trail (to the end and back):
3 1/2 miles to the end + 3 1/2 miles back = 7 miles
The total distance for the Wildflower Trail:
2 3/8 miles
Adding both distances gives us:
7 miles (Tremont Trail) + 2 3/8 miles (Wildflower Trail) = 9 3/8 miles
Therefore, Bernie and Chloe hiked a total of 9 3/8 miles.
