Answer:
D
Step-by-step explanation:
3 represents skateboards and 1 represents bikes. We need to get from 3 to 12 and 1 to the answer by using the same number you used to get from 3 to 12.
To get from 3 to 12 you multiply by 4
3*4=12
So let's go ahead and multiply 1 by 4 as well
1*4=4
Your ratio is now 12:4 and 4 stands for bikes so there are 4 bikes

Jillian and Josie are trying to find the value of the function, 8x^4-12x^3+3x^2-7x+4 at x=-1. Jillian says the only way to find the answer is to plug in -1. Josie says, no, there is another way. Who is right? Justify your answer.
Answer:
Josie is correct.
Step-by-step explanation:
There are other ways of finding the value of the function at x = 1.
For example, one way would be graphing or using a graphing device to graph the function. Once graphed, looking for the y-value where x = 1 would also provide the answer.
Which equation has a axis of symmetry of x=4 ?
I think you forgot to add the picture. However, any x = 4 equation will result in a graph with a vertical line on the x-axis. For example x = 20 will be a vertical line on x-axis 20.
Or, in a more difficult equation like this...
10x - 60 = 10
10x = 10 +60
10x = 70
x = 7,
where the graph looks like a vertical line with a point on the x axis on 7.
The box and whisker plots represent the number of minutes spent by users on two different social media groups. Which THREE statements are correct when comparing the plots?
A) The median time for users of Group B is 40 minutes.
B) Group B has greater median value than Group A.
C) The data for Group B varies slightly more than Group A.
D) The spread of the data for Group A is 25 minutes.
E) The spread of the data for Group A is 40 minutes.
Answer: I feel the answer is C
Step-by-step explanation:
The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.
What is a box and Whisker plot?A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.
Let's analyze each of the given statements given the box and whisker plots for both groups:
Statement A is TRUE:
Median time for Group B = 40.
Statement B is FALSE:
Median value for Group A is between 45 and 50
Median value for Group A is 40.
Therefore, Group B does NOT have median value greater than Group A.
Statement C is TRUE:
The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.
Statement D is TRUE while E is FALSE:
Spread for Group A (IQR) = 55 - 30 = 25 minutes
Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

Mila owns a small business selling used books. She knows that in the last week 83 customers paid cash, 16 customers used a debit card, and 41 customers used a credit card. Based on these results, express the probability that the next customer will pay with something other than a credit card as a decimal to the nearest hundredth
Answer:
the answer is 0.71
Step-by-step explanation:
it told me
The probability the next customer will pay with something other than a credit card is 0.71.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
Number of customers paid cash = 83
Number of customers used a debit card = 16
Number of customers used a credit card = 41
Total number of customers = 140
The probability that the next customer will pay with something other than a credit card is
P(e) = (Number of customers paid cash + Number of customers used a debit card) / Total number of customers.
⇒ [tex]P(e)=\frac{83+16}{140}[/tex]
⇒ [tex]P(e)=\frac{99}{140}[/tex]
⇒ [tex]P(e)=0.7071[/tex] ≈ [tex]0.71[/tex]
Hence we can conclude that the probability the next customer will pay with something other than a credit card is 0.71.

a store offers a discount of 40 off any one regular-priced item. employees also get 10% off any purchases. in which order should the discounts apply so that the employee pays the least amount?
A. Employee discount then store discount
B. They are both the same
C. Store discount then employee discount
Let's say the price of an item is $1
Scenario #1 - 40% off $1 = 40 cents OFF
The discounted price = 60 cents
Now the 10% off of 60 cents
60-6 = 54 cents.
Scenario #2 - 10% of $1
The discounted price = 10 cents
100(cents) - 10 = 90 cents
Now the 40% off of 90 cents
90-36 = 54 cents
Let's try another value to confirm
Let's say the price of an item is $2
Scenario #1 - 40% off $2 = 80 cents OFF
200-80= 120 = $1.20
Now the 10% off of $1.20
120-12= 108 = $1.08
Scenario #2 - 10% off $2 = 20 cents OFF
200-20 = 180= 1.80
Now the 40% off of $1.80
180-72 = 108 = 1.08
With these two examples we can confirm either order
will give you the same savings.
Answer:
B. They are both the same

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the y-intercept, (0, 62), and the point (6, 80) from the line on the scatter plot. What is the equation of the trend line? (*Note: Enter your response as an equation in y=mx+b form. Enter no spaces & use only lower-case letters. Ex: y=10x+5 ) *
Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62

x 2 +2x+y 2 =0 what is the center and radius of the circle?
Center = (-1,0) Radius= 1
when you complete the square your equation should look something like
(x²+2x+1) (y²+0) = 1.The 1 on the left side coming from (b/2)² which is (2/2)² which equals 1 and whatever you add to one side, you have to add to the other so when you add 0+1 you get the 1 on the right side. Then factor or use the (b/2) from earlier without the ² so you should get (x²+1) + (y²+0) = 1. Flip the sign so you have negative 1 and 0. For the radius, square the right side and of course, [tex]\sqrt{1}[/tex] is simply 1 so your radius is 1. A lot of 1's huh? lol at least it makes the operations nice and simple :)
