Let x be the price per pound of apples and y be the price per pound of potatoes.
For Ethan, the total cost for apples was $25.50 - 5y and the total cost for potatoes was $25.50 - 8x.
So, we have the following two equations:
8x + 5y = 25.5
3x + 10y = 18.5
Solving this system of linear equations, we get:
x = 1.71 and y = 2.36.
So, the ordered pair (x,y) = (1.71, 2.36) represents the price per pound of apples and potatoes.

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y=64(0. 13)
The given exponential function represents decay since the base (0.13) is less than 1. And the percentage decrease of 91.68%.
The percentage rate of the decrease can be determined by taking the base and subtracting it from 1 and then multiplying the result by 100. Mathematically, this can be expressed as (1 - 0.13)*100 = 87%. To illustrate this mathematically, let's assume that the initial value of y is 100. We can then calculate the value of y after one time period (t) as follows: y = 64(0.13)t.
Plugging in t = 1, we get y = 64(0.13) = 8.32. This means that the value of y has decreased by (100 - 8.32) = 91.68, or a decrease of 91.68%. Dividing this by the initial value of 100 gives us a percentage decrease of 91.68%/100 = 0.9168 or 91.68%.

Jodi found a pair of jeans on sale for $90. Her friend told her that was only 75% of the original price. What was the original price of the jeans?
The original price of the pair of jeans is equals to the $120.
We Jodi wants to buy a pair of jeans.
The purchase price of pair of jeans = $90
Discount on price of jeans = 75%
Let the original price of pair of jeans be equal to "$x". Percent is an important concept of mathematics. It is a number or ratio of fraction of hundred. It is denoted by symbol %. The formula is
% = ( part /whole )×100
Here, it is said that the price of pair of jeans, $90, is only 75% of the original price. So, we can write it as the following way 75% of x = 90
=> (75/100) of x = 90
=> (75/100) × x = 90
=> x = 90× 100/75
=> x = 9000/75
=> x = 120
Hence, required value of x is 120.

Graph this line using the slope and y-intercept: y=6x+1
Answer:
shown below
Explanation:
you can take the y-intercept and plot that right away. The y intercept for this equation is 1, so you plot a point at (0,1). Then you can use the slope to find your next point. You can put the slope, 6, into a fraction form, making it “6/1” then you use rise/run and go up 6, over 1, and plot your next dot at (7,1). You then take a straight edge and graph the line that intercepts both points. It looks like the picture below.

A significance test about a proportion is conducted using a significance level of 0.05. The sample statistic is 0.12. The p-value is 0.03.a) If H0 were true, for what probability of a Type I error was the test designed?b) What conclusion (reject or fail to reject) would you make for this test?c) If this test resulted in a decision error, what type of error was it?
For the significance test given, the error will be a type one error.
The results of tests for statistical significance show whether apparent variations in assessment results are the product of random variation or sampling mistake. The given parts can be answered as -
a) The analysis of the given question was conducted with a likelihood of .05 for a type one error. This is because the level of significance for it is .05 as well. Therefore, such a situation implies that regardless of whether the null hypothesis is correct and accurate there is still a five percent chance that it will be incorrect or will be rejected.
b) The probability that a representative sample will be equally extreme or more intense than the one that was correctly predicted is known as the p-value when the null hypothesis is true. In this case, the p-value is only .03 and drops below the .05 criterion of significance. This reveals that the generic parameter-supported null thesis is categorically rejected. This study would thus, further result in the rejection of the null hypothesis.
c) A decision error from the test could be either a Type I error or a Type II error. While a Type II error happens when the null hypothesis is true but not rejected, a Type I error happens when the opposite is true. Since the null hypothesis was true but was rejected by chance in this situation, any judgement error that the test produced would be of the Type I variety.

a six-sided number cube numbered 1 through 6 was tossed 150 times. the results are shown in the table. number cube results,. number,. frequency,. 1,. 16,. 2,. 28,. 3,. 24,. 4,. 15,. 5,. 37,. 6,. 30,. what is the experimental probability that the next toss will result in an odd number?
The experimental probability of getting an odd number on the next toss is 51.3%.
Probability is a measure of the likelihood of an event occurring. In the case of the six-sided number cube, the theoretical probability of getting an odd number on any one roll is 3 out of 6, or 1/2, or 50%. However, this is a theoretical value and may not match the actual results obtained from a set of experiments.
The experimental probability of an event is calculated by observing the actual results of a series of trials and comparing it to the number of possible outcomes. In this case, the number cube was tossed 150 times and the results were recorded in the table. The frequency of the odd numbers (1, 3, and 5) was found to be 77.
The experimental probability of getting an odd number on the next toss can be calculated by dividing the frequency of the odd numbers by the total number of tosses, which is 150. 77/150 = 0.513 or 51.3%.
Therefore, the experimental probability of getting an odd number on the next toss of the six-sided number cube is 51.3%.

Why is it important to use a device like a random number table in a simulation?
A. Chance plays a part in the process being simulated.
B. It helps to organize the data.
C. The calculations are difficult to complete by hand.
D. Random number tables include critical values
It is important to use a device like a random number table in a simulation because Option A Chance plays a part in the process being simulated.
In simulations, a random number table is used to incorporate the element of chance into the process being modeled. The reason this is important is that many real-world processes involve uncertainty and randomness, and to accurately simulate these processes, it is necessary to include these elements.
For example, in simulating the stock market, stock prices can be modeled as random variables, because they are influenced by a variety of unpredictable factors such as changes in interest rates, company earnings, geopolitical events, and investor sentiment. To simulate this process, a random number table can be used to generate random numbers that represent these unpredictable factors.
By using a random number table, the simulation can model the uncertainty and randomness inherent in the real-world process, which makes the simulation more accurate and realistic. This is why it is important to use a device like a random number table in a simulation when chance plays a part in the process being simulated.

b) Edward and Thomas share some money in the ratio 2:3 Thomas receives £243. How much does each Robert receive?
Answer:
£ 162
Step-by-step explanation:
Ratio:
Ratio of money = 2 : 3
Edward receives two parts of the money and Thomas receives three parts of the money.
Edward's share = 2x
Thomas share = 3x
Thomas receives £243 which is three parts. Find 'x'.
Thomas share = £ 243
3x = 243
Divide both sides by 3,
x = 243 ÷ 3
x = 81
Now, find Edward's share.
Edward's share = 2x
= 2*81
= £ 162
Answer:
£ 162
Step-by-step explanation:
Ratio:
Ratio of money = 2 : 3
Edward receives two parts of the money and Thomas receives three parts of the money.
Edward's share = 2x
Thomas share = 3x
Thomas receives £243 which is three parts. Find 'x'.
Thomas share = £ 243
3x = 243
Divide both sides by 3,
x = 243 ÷ 3
x = 81
Now, find Edward's share.
Edward's share = 2x
= 2*81
