The answer is below
Step-by-step explanation:
1) Let x represent the price of Tacos and y represent the price of Burrito. You where charged $4.80, hence:
2x + 2y = 4.80; Dividing through by 2:
x + y = 2.4 (1)
Your friend was charged $4.00, hence:
3x + y = 4.00 (2)
Solving equation 1 and 2 simultaneously by subtracting equation 2 from equation 1:
2x = 1.6
x = 0.80
Put x = 0.8 in equation 1:
0.8 + y = 2.4
y = 1.60
The cost of each tacos is $0.80 and the cost for each burritos is $1.60
2) Let x represent the smaller number and y the bigger number, hence:
y - x = 16 (1)
Also:
y = 4x - 5;
y - 4x = -5 (2)
Subtract equation 2 from equation 1 to solve simultaneously:
3x = 21
x = 7
Put x = 7 in equation 1:
y - x = 16
y - 7 = 16
y = 23
The greater number is 23 and the smaller number 7

if each value of the data of the poplation function is doubled which of the following is not correct?
A. the mean is doubled
B. the mode is doubled
C. the variance is doubled
D. the median is doubled
Answers
Answer:
The variance is doubled; C
Step-by-step explanation:
Here, we want to select what will be wrong if every number in the dataset is doubled
A. This is correct
The mean is the average of the numbers which is calculated by dividing the sum of the numbers by the count of the numbers
By doubling the numbers, we have simply doubled the sum while the count is same
So what we have as the result of the division will be 2 times what we had initially making the mean doubled
B. The mode is doubled
Yes, this is correct
The mode is the highest in frequency
Doubling all numbers will not double their frequencies but their values. So the number that was the mode in the previous case will be the same but now doubled
D. The median is doubled
This is correct
The median deals with the middle number.
Since all numbers are doubled in the present case, the median to is also doubled along side as the numbers are now twice what they were evenly
C. This is wrong
The variance has to do with the spread of data
We are actually subtracting values
Since we are doubling across board, the difference between the numbers is the same as this, the variance cannot change
We can look at this from the angle that all others are measures of central tendency looking at having a central figure while the variance is a measure of spread.

Aidan makes a snack mix for a party using ½ bag of chips for every 2 bags of
cheetos. How many bags of cheetos did he use if he used 1 bag of chips?
Answers
Therefore, for 1 bag of chips, he used 4 bags of Cheetos.
Given that 1/2 bag of chips is used for every 2 bags of Cheetos.
Now we have to determine how many bags of Cheetos did he use if he used 1 bag of chips as
1/2 bag of chips = 2 bags of Cheetos
1 bag of chips = x
1/2 / 1 = 2 / x
By cross multiplying we get
1/2 x = 2
x = 2 / 1/2
x = 2 * 2
x = 4
Therefore, for 1 bag of chips, he used 4 bags of Cheetos.

Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
Slope m = 2/7
y-intercept b = 0
Step 2: Write equation
Substitute [Form]: y = 2/7x + 0Simplify: y = 2/7xExplanation: Slope-intercept form is y=mx+b the m meaning slope and the b meaning y-intercept, so by plugging in the variables in slope-intercept form it's y=2/7x+0; since the y-intercept is 0 it doesn't need to be in the equation so it's y=2/7x

Since the room temperature is 22 degrees Celsius,

Solving the differential equation,

When t=0, the temperature is 100 degrees.

When t=1, the temperature is 80 degrees.
