how do I make a stem and leaf plot?
with pictures
Answers
Step-by-step explanation:
To make a stem and leaf plot, each observed value must first be separated into its two parts:
1)The stem is the first digit or digits;
2)The leaf is the final digit of a value;
3)Each stem can consist of any number of digits; but,
4) Each leaf can have only a single digit.

Answers
Answer:
That statement is true, but you do not always need the two.
Let's say that we had a problem, given the radius is 5, and we have to find the diameter.
First step is to define A
[tex]A = \pi r^2[/tex]
Second, redefine r as the actual radius to avoid confusion.
[tex]r = 5[/tex]
Third, set up an equation with the given values where you are multiplying pi by the radius.
[tex]\pi r^2 = \pi *r^2[/tex]
Fourth but not least, get the actual value.

Answers
Answer:
2√3
Step-by-step explanation:
root 27
= √27
= 3√3
12 upon root 3
= 12 / √3
= ( 12 / √3 ) x ( √3 / √3 )
= ( 12 x √3 ) / ( √3 x √3 )
= 12√3 / 3
= 4√3
6 upon √3
= 6 / √3
= ( 6 / √3 ) x ( √3 / √3 )
= ( 6 x √3 ) / ( √3 x √3 )
= 6√3 / 3
= 2√3
root 3 = √3
root 3 + root 27 - 12 upon root 3 + 6 upon root 3

1000x+27x+5.5=9236
Answers
Answer:
x = 8.98782862707
Step-by-step explanation:
Base on the given we can infer that we are solving for x:
Given equation:
1000x+27x+5.5=9236
Combine similar terms
1027x + 5.5 = 9236
Subtract both side by 5.5
1027x + 5.5 = 9236
-5.5 -5.5
-------------------------------------
1027x = 9230.5
Now divide both sides by 1027x
9230.5 / 1027
x = 8.98782862707

at which point do the two equations 3x+5=y+4x and y=x2 intersect? problem is the picture below, the choices are there.
Answers
Answer:
A. and D.
Step-by-step explanation:
Hey there!
In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:
[tex]y=mx+b[/tex]
or
[tex]y=ax^2+bx+c[/tex]
The first equations needs to be rewritten
[tex]3x+5=y+4x[/tex]
make [tex]y[/tex] by itself
[tex]3x+5-4x=y[/tex]
Simplify LHS
[tex]y=-x+5[/tex]
Now we have it in slope-intercept form
Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5
Now you can graph this equation easily (image down below)
The second equation is already in form so there is no need to rewrite anything
We can go straight to graphing (image down below)
Now plot both equations on the same graph (image down below)

Dan spent $24 at the store
Which equation could be used to calculate p, the amount Paul spent?
A. P-4=24
B. 4p=24
C. 4+24=p
D. 4+p=24
Answers
Answer:
D 4+p=24
Step-by-step explanation:
So P stands for Paul & how much he spent.
Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20. So P = $20
So which equation would work if you substituted $20 for P?
4 + P = 24
4 + 20 = 24

[tex]\textsf{let}\:(x_1,y_1)=(-1,5)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(1,-3)[/tex]
Calculate the slope using the slope formula:
[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-3-5}{1-(-1)}=-4[/tex]
From inspection of the graph, it appears that the y-intercept (where the line crosses the y-axis) is at (0, 1). However, just to be sure, use the point-slope form of linear equation.
Point-slope form of linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where m is the slope and (x₁, y₁) is a point on the line)
[tex]\implies y-5=-4(x-(-1))[/tex]
[tex]\implies y-5=-4x-4[/tex]
[tex]\implies y=-4x+1[/tex]
Therefore, the equation of the line in slope-intercept form is:

Answers
The total amount of money that Stephen would pay his uncle is equal to $10,600.
How to calculate simple interest.Mathematically, simple interest is calculated by using this formula:
I = PRT
Where:
I is the simple interest.P is the principal.R is the interest rate.T is the time measured in years.Given the following data:
Interest rate = 2% = 0.02.
Principal = $10,000.
Time = 3 years.
Substituting the given parameters into the formula, we have;
I = 10000 × 0.02 × 3
I = $600.
Amount of balance;
A = I + P
A = 600 + 10,000
A = $10,600.

6 blue chips 13 pink chips 7 white chips Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? PLEASE HELLPP

Answer:
9/169Step-by-step explanation:
Total number of chips

P(blue) = blue / total = 6 / 26 = 3/13The subsequent blue has same probability as the chip is replaced.
Probability of two blue chips is
P(blue, blue) = 3/13*3/13 = 9/169Answer:
[tex]\sf \dfrac{9}{169}[/tex]
Step-by-step explanation:
The bag has:
6 blue chips13 pink chips7 white chips⇒ Total number of chips = 6 + 13 + 7 = 26
Probability Formula
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Probability of choosing a blue chip from the first draw:
[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]
As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.
Therefore, the probability of taking out a blue chip in both draws is:

Starbucks Coffee Co. Uses a data-based approach to improving the quality and customer satisfaction of its products. When survey data indicated that Starbucks needed to improve its package-sealing process, an experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. (Data extracted from L. Johnson and S. Burrows, "For Starbucks, Itâs in the Bag," Quality Progress, March 2011, pp. 17â23. ) One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag-sealing equipment. Data were collected on 19 bags in which the plate gap was varied. The results are stored in Starbucks.
a. Construct a scatter plot.
b. Assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1.
c. Interpret the meaning of the slope, b1, in this problem.
d. Predict the mean tear rating when the plate gap is equal to 0.
e. What should you tell management of Starbucks about the relationship between the plate gap and the tear rating?
Answers
When there's a linear relationship, the least-squares method to determine the regression coefficients b0 and b1 will be y = 0.750 + 0.50x.
How to interpret the slope?The meaning of the slope, b1, in this problem is the coefficient of x which is the slope. Here, b1 = 0.50. It implies that one unit change in x will be 0.5 unit change in y.
To predict the mean tear rating when the plate gap is equal to 0 goes thus:
y = 0.75 + (0.05 × 0)
y = 0.75 + 0
y = 0.75
Lastly, the relationship between the plate gap and the tear rating is a positive one.
