on monday ramon bought 5 zip disks. two days later the price of the discs were decreased by 1.50 per disk. leticia bought ten disks at the sale price and paid 22 more than ramon paid for 5 disks. what was the original price of a disk
Answers
The original price of a zip disk is; $1.4
How to Solve Algebra Word Problems?Let cost of zip sticks bought by Ramon be x. Thus;
Cost that Ramon paid = 5x
Now, we are told that 2 days later the price increased by $1.5 per disc. Thus, new cost = x + 1.5
Leticia bought ten disks at the sale price and paid 22 more than ramon paid for 5 disks. Thus, equation here is;
10(x + 1.5) = 5x + 22
Expand the bracket to get;
10x + 15 = 5x + 22
10x - 5x = 22 - 15
5x = 7
x = 7/5
x = $1.4

Find the distance between points A and B. A = (3,-7) B = (3,1)
Answers
The distance between points A and B is 8 units.
We have been given two points A and B.
The coordinates of the points are A = (3,-7) B = (3,1)
We need to find the distance between points A and B.
Let d be the distance between points A and B.
Using distance formula,
d = √[(3 - 3)² + (1 - (-7))²]
d = √[0² + 8²]
d = √8²
d = 8 units
Therefore, the distance between points A and B is 8 units.

Answers
The equation of the linear function represented by the table below in slope-intercept form is y = 5x + 4
Linear equationsThe equation of a line in point-slope form is expressed as y = mx + b
where
m is the slope
b is the intercept
Using the coordinate points (-1,-1) and (2, 14)
Slope = 14+1/2+1
slope = 15/3
Slope = 5
For the intercept;
14 = 5(2) + b
14 = 10 + b
b = 4
The y-intercept is at the point (0,4)

Caroline's age is 21 years which is an odd integer.
Integers are a subset of real numbers.
Integers are rational numbers except decimals and fractions.There are 3 types of integers positive , negative and Zero.Positive integers are 3, 6, 789 ...Negative integers are -87, -345, -234 ...Zero integers is 0It is given that Caroline is the youngest of 4 siblings and all of their ages are odd consecutive integers.
Let us consider the age of Caroline's age to be x years(x is an odd integer).
She is the youngest so the sibling's age who is just older than Caroline is given by x+2 which is also another odd integer.
Ages of the other two siblings will be x + 4 , x + 6 .
Now sum of their ages is 96.
Therefore: x + (x+2) + (x+4) + (x+6) =96
or, 4x + 12 = 96
or, 4x = 84
or, x = 21 (odd integer)

Answers
The critical value that should be used in constructing the confidence interval is ( 1.592, 1.807 ).
Given that;
Number of residents, n = 7
Z*- value of 90% confidence level equals z* = 0.79
Mean x = 1.7 and deviation σ = 0.36
What is the standard deviation?
Standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean.
Now,
Number of residents, n = 7
Z*- value of 90% confidence level equals z* = 0.79
Mean x = 1.7 and deviation σ = 0.36
The confidence interval for mean waste recycled per person is
