You have been saving your money to buy a new pair of shoes. Three different stores are having a sale on them. Which store has the best deal?
Store A
Original Price: $70
Take 10% off.
Then, take 10 percent off that price.
Store B
Original Price: $80 Take $15 off.
Then, take 10 percent off that price.
Store C
Original Price: $90
Take 10% off.
Then, take $20 off that price.
A) Store A
B) Store B
C) Store C
Answer:
Store A would be the least expensive.
Step-by-step explanation:
Store A
70*0.10=7
70-7=63
63*0.10=6.30
63-6.30=57.70
$57.70
Store B
80-15=65
65*0.10=6.50
65-6.50=58.50
$58.50
Store C
90*0.10=9
90-9=81

Zoya sells insurance. She earns $10,25/hour and 8% commission on all her sales. Last week
she worked 35 hours and sold $2058 worth of insurance. How much did she eam all together?
Answer:
$523.39
Explanation:
10.25 x 35 hours= 358.75
2058 x 8/100 = 164.64
358.75 + 164.64 = 523.39
The claim is that for 10 am body temp of males the mean is less than 98.6 f the sample size is n = 38 and the test statistic is t=-3.768
Answer:
See below
Step-by-step explanation:
The null hypothesis would be [tex]H_o:\mu\leq98.6[/tex] which would suggest the claim that the mean body temperature for males is equal to or less than 98.6°
The alternate hypothesis would be [tex]H_1:\mu>98.6[/tex] which would suggest that the mean body temperature for males is greater than 98.6°
The test statistic, t, is given to us as [tex]t=-3.77[/tex], rounded to 2 decimal places
We can determine the p-value by calculating tcdf(-1e99,-3.77,37). This means that we are finding the area less than the t-statistic with degrees of freedom equal to df=n-1=38-1=37. Therefore, the p-value is 0.000285 when evaluated.
Therefore, because our p-value is less than our significance level of α=0.01, there is no sufficient evidence to prove that the claim that for 10 AM body temperatures for males, the mean is less than 98.6°F, is true. We reject the null hypothesis, in other words, because the p-value suggests that it's unlikely that the null hypothesis is true.
The null hypothesis is rejected since the p-value shows that it is unlikely to be true.
What is the hypothesis?In statistics, hypothesis testing is the process by which an analyst tests an assumption about a population's parameter. Using sample data, hypothesis testing is performed to examine the plausibility of a theory.
As per the given question, the required solution would be as:
A) Hypothesis test :
The null and alternative hypothesis is
Hi : u = 98.6
Ha : u < 98.6
B) Test statistic is t = -3.831
C) sample size, n= 31
degree of freedom,
df = n -1 = 31 - 1 = 30
P-value = p(t < -3.831 )
= 0.0003 (from t table)
d) P-value < 0.10, reject the null hypothesis.
is, support
As a result, because our p-value is less than our significance level of =0.01, there is insufficient evidence to support the assertion that the mean body temperature for men at 10 AM is less than 98.6°F.
Thus, we reject the null hypothesis since the p-value shows that it is unlikely to be true.

Luisa buys a plane ticket that has an original price of $240. She used a coupon code to get 30% discount off of the original price.She is then charged a 7% tax on the discounted price
Answer:
The final cost after the discount and tax is $179.76
Step-by-step explanation:
Since the discount is 30%, she only pays 70% of the price of the ticket.
Discounted price before tax:
70% of $240 = 0.7 × $240 = $168
Now think of the price $168 as a new price.
The price is $168 which is 100% of the price. Tax is 7% of the price, so you must pay 107% of the price.
107% of $168 = 1.07 × $168 = $179.76
Answer: The final cost after the discount and tax is $179.76

Five whole numbers are written in order.
4 6 х у

The mean and median of the five numbers are the same.
Work out the values of x and y.
Answer:
x = 7, y = 8Step-by-step explanation:
Given numbers in order:
4, 6, x, y, 10The mean is same as median.
The median is x as middle number. Since x is a whole number, the mean is also a whole number.
x and y can be selected from 7, 8 or 9 (numbers between 6 and 10).
The mean is:
(4 + 6 + x + y + 10)/5 =(20 + x + y)/5 = 4 + (x + y)/5It should be a whole number, so (x + y) should be divisible by 5.
The option is (7 + 8) = 15, and 9 is excluded.
Let's verify:
Median = x = 7Mean = 4 + (7 + 8)/5 = 4 + 3 = 7Mean:-

what is the value of m in the figure below?
==========================================================
Explanation:
First we'll need the length of segment BD, which I'll call x for now. The similar triangles allow us to set up the proportion below to solve for x
AD/BD = BD/DC
13/x = x/4
13*4 = x^2
52 = x^2
x^2 = 52
x = sqrt(52)
Segment BD is exactly sqrt(52) units long.
------------
Now focus your attention on triangle BDC. We'll use the pythagorean theorem to find BC
(BD)^2 + (DC)^2 = (BC)^2
( sqrt(52) )^2 + ( 4 )^2 = ( m )^2
52 + 16 = m^2
68 = m^2
m^2 = 68
m = sqrt(68)
m = 8.2462 approximately
m = 8.2

Which of the following rules could represent the function shown in the table?
Answer:
f(x) = 2x + 1.
Step-by-step explanation:
In order to determine the function rule for the given table of values, we must start by finding the slope or the rate of change. Choose two ordered pairs from the table: (0, 1) and (1, 3).
Let (x₁, y₁) = (0, 1)
(x₂, y₂) = (1, 3)
Substitute these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (3 - 1)/(1 - 0)
m = 2/1 = 2
Therefore, the slope of the function is, m = 2.
Next, we must determine the y-intercept, which is the point on the graph where it crosses the y-axis, with coordinates of (0, b ). From the given table of values, the y-intercept is (0, 1), for which its y-coordinate is the value of b = 1.
Therefore, the function rule that represents the given table of values is:
f(x) = 2x + 1.Maggie needs $180 to pay for a cheer camp. She has $30 already and saves $30 a week that she earns by helping her neighbors.
Use the Segment tool to plot a graph representing the amount of money Maggie has saved from the time she begins saving until she has saved enough for cheer camp.
We want to graph the linear function that models how much Maggie saves, the graph can be seen below.
So we know that maggie starts with $30, and she saves another $30 per week, then after x weeks, the total amount that she has saved is:
S(x) = $30 + $30*x
Now we have the function, to graph it, we just need to get two points of the function and then connect them with a line, to get these points, we just evaluate the function in two different values of x:
S(0) = $30 + $30*0 = $30
S(1) = $30 + $30*1 = $60
So we have the points (0, $30), (1, $60).
Now we just need to graph these points and connect them with a line, the graph can be seen below.
