Magdalena buys a lawnmower that costs $122.50. The
sales tax in her town is 8%. Write an equation of the
form y=kx to represent the amount of tax on an item
that costs x dollars. Use the equation to find the
amount of tax on the lawnmower. SHOW YOUR WORK. i need help asap!
Answers
Answer:
Here u go :3
Step-by-step explanation:
p = price
p=122.50x
x = 8%
122.50 * 0.08 = 9.80
The amount of sales tax on the lawnmower is $9.80.
A sales tax is a form of tax that is levied on the purchase of goods and services. Taxes increase the cost of a good or service. The amount of tax paid can bee determined by multiplying the tax rate by the cost of the lawnmower.
The amount of tax paid = cost of the lawnmower x sales tax
= $122.50 x 0.08
= $9.80

identify this lobe and y-intercept of the line given by y equals to 4 x - 3
Answers
Answer:
Slope = 4
y-intercept = -3
Step-by-step explanation:
A slope describe the steepness of a graph, which can also be referred to as gradient. The general equation of a linear graph is given as:
y = mx ± c
where: m represents the slope of the graph and c the intercept on the required axis.
Given: y = 4x - 3
Comparing this equation with the general equation of a linear graph, it can be observed that; the slope is 4, while the intercept on the y axis is -3.
Thus,
slope = 4
intercept on the y axis = -3

The inequality should be written as 25 s less-than 300.
The inequality should be written as 25 s greater-than 300.
The circle is open.
The circle is closed.
The arrow points left.
Answers
The correct options are 1, 3 and 5.
Step-by-step explanation:
Let the price of a new shirts be s.
The number of members is 25. The price of 25 shirts is 25s.
The cost must be less than $300. It means
Therefore option 1 is correct.
Divide both sides by 25.
The sign of inequality is < instead of ≤. It means the 12 is not included in the solution set.
Open circle is used for "<" and ">". Closed circle is used for "≤" and "≥".
Since the sign of inequality is <, therefore the circle is open and option 3 is correct.
The value of s is less than 12.
Therefore the arrow points left and option 5 is correct.

Calculate the average rate of change from 3 to 9 seconds, in feet per second
Answers
Answer:
D is the Answeer
Step-by-step explanation:
Average rate of change from 3 to 9 seconds is -0.475 feet per second
What is Average rate of change?It is a measure of how much the function changed per unit, on average, over that interval
Given,
P(t) represents the height in feet and t represents the time in second
At t= 3 second, P(t) = 6.26 feet
At t=9 second, P(t) = 3.41 feet
Average rate of change = [tex]\frac{P(b)-P(a)}{b-a}[/tex]
Substitute the values in the equation
Average rate of change = [tex]\frac{P(9)-P(3)}{9-3}[/tex]
[tex]=\frac{3.41-6.26}{9-3}\\=\frac{-2.85}{6}\\[/tex]
= -0.475 feet per second
Hence, the Average rate of change from 3 to 9 seconds is -0.475 feet per second

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.2.a. If the distribution is normal, what is the probability that the sample mean hardness for a random sample of 9 pins is at least 51?b. Without assuming population normality, what is the (approximate) probability that the sample mean hardness for a random sample of 40 pins is at least 51?
Answers
Answer:
a
[tex]P(\= X \ge 51 ) =0.0062[/tex]
b
[tex]P(\= X \ge 51 ) = 0[/tex]
Step-by-step explanation:
From the question we are told that
The mean value is [tex]\mu = 50[/tex]
The standard deviation is [tex]\sigma = 1.2[/tex]
Considering question a
The sample size is n = 9
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_x = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_x = \frac{ 1.2 }{\sqrt{9} }[/tex]
=> [tex]\sigma_x = 0.4[/tex]
Generally the probability that the sample mean hardness for a random sample of 9 pins is at least 51 is mathematically represented as
[tex]P(\= X \ge 51 ) = P( \frac{\= X - \mu }{\sigma_{x}} \ge \frac{51 - 50 }{0.4 } )[/tex]
[tex]\frac{\= X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ \= X )[/tex]
[tex]P(\= X \ge 51 ) = P( Z \ge 2.5 )[/tex]
=> [tex]P(\= X \ge 51 ) =1- P( Z < 2.5 )[/tex]
From the z table the area under the normal curve to the left corresponding to 2.5 is
[tex]P( Z < 2.5 ) = 0.99379[/tex]
=> [tex]P(\= X \ge 51 ) =1-0.99379[/tex]
=> [tex]P(\= X \ge 51 ) =0.0062[/tex]
Considering question b
The sample size is n = 40
Generally the standard error of the mean is mathematically represented as
[tex]\sigma_x = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma_x = \frac{ 1.2 }{\sqrt{40} }[/tex]
=> [tex]\sigma_x = 0.1897[/tex]
Generally the (approximate) probability that the sample mean hardness for a random sample of 40 pins is at least 51 is mathematically represented as
[tex]P(\= X \ge 51 ) = P( \frac{\= X - \mu }{\sigma_x} \ge \frac{51 - 50 }{0.1897 } )[/tex]
=> [tex]P(\= X \ge 51 ) = P(Z \ge 5.2715 )[/tex]
=> [tex]P(\= X \ge 51 ) = 1- P(Z < 5.2715 )[/tex]
From the z table the area under the normal curve to the left corresponding to 5.2715 and
=> [tex]P(Z < 5.2715 ) = 1[/tex]
So
[tex]P(\= X \ge 51 ) = 1- 1[/tex]
=> [tex]P(\= X \ge 51 ) = 0[/tex]
Using the normal distribution and the central limit theorem, we have that there is a:
a) 0.0062 = 0.62% probability that the sample mean hardness for a random sample of 9 pins is at least 51.
b) 0% approximate probability that the sample mean hardness for a random sample of 40 pins is at least 51.
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
Mean of 50, hence [tex]\mu = 50[/tex]Standard deviation of 1.2, hence [tex]\sigma = 1.2[/tex]Sample of 9, hence [tex]n = 9, s = \frac{1.2}{\sqrt{9}} = 0.4[/tex].Item a:
The probability is 1 subtracted by the p-value of Z when X = 51, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{51 - 50}{0.4}[/tex]
[tex]Z = 2.5[/tex]
[tex]Z = 2.5[/tex] has a p-value of 0.9938.
1 - 0.9938 = 0.0062
There is a 0.0062 = 0.62% probability that the sample mean hardness for a random sample of 9 pins is at least 51.
Item b:
Even though the distribution is not normal, the sample size is of [tex]n = 40 > 30[/tex], hence the Central Limit Theorem can be applied.
[tex]s = \frac{1.2}{\sqrt{40}} = 0.19[/tex]
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{51 - 50}{0.19}[/tex]
[tex]Z = 5.26[/tex]
[tex]Z = 5.26[/tex] has a p-value of 1.
1 - 1 = 0
0% approximate probability that the sample mean hardness for a random sample of 40 pins is at least 51.

Answers
Answer:
500 gallons per hour
Step-by-step explanation:
rate =2000-500 gallons/ 3hours
=1500 gallons/3 hours
=500gallons per hor
Using mathematical operations, we know that the rate of change is 500 gallons of water per hour.
What are mathematical operations?The rules that specify the order in which we should solve an expression involving many operations are known as the order of operations. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (from left to right). An operation is a function in mathematics that transforms zero or more input values into a clearly defined output value. The operation's arity is determined by the number of operands.So, the rate of change:
Hours passed is 3. (11 - 8 = 3)The water decreased after 3 hours is 1500. (2000 - 500 = 1500)Now, calculate as follows:
Rate of change = 2000 - 500/3Rate of change = 1500/3Rate of change = 500 per hourTherefore, using mathematical operations, we know that the rate of change is 500 gallons of water per hour.
