Answer:
x = -2
y = 9
Step-by-step explanation:
y = -3x + 3
y = 5x + 19
We can put one y as another:
-3x + 3 = 5x + 19
-8x = 16
x = -2
And now let's check using x = -2
y = (-3 * -2) + 3
y = (5 * -2) + 19
y = 6 + 3
y = -10 + 19
y = 9
y = 9

How can I determine the line of best fit, and how will this help me to make predictions?
Answer:
A line of best fit is drawn through a scatterplot to find the direction of an association between two variables. This line of best fit can then be used to make predictions. To draw a line of best fit, balance the number of points above the line with the number of points below the line.

Martin is an artist who molds plaster into unique shapes. How much plaster can Martin fit into the mold shown? Cuboid with length as 1 ft, height as 2 ft and width as 1 ft. Is placed above the cuboid with length, height and width as 4 ft. A. 66 ft3 B. 80 ft3 C. 128 ft3 D. 256 ft3
Answer:
[tex]Amount = 66ft^3[/tex]
Step-by-step explanation:
No attachment given, but the question can still be solved.
Given
Cuboid 1
[tex]Length = 1ft[/tex] [tex]Width = 1ft[/tex] [tex]Height = 2ft[/tex]
Cuboid 2
[tex]Length = Width = Height = 4ft[/tex]
Required
How much plaster can fit in
To do this, we simply calculate the volume of the shape
For cuboid 1
[tex]Volume = Length * Width * Height[/tex]
[tex]V_1 = 1 * 1 * 2[/tex]
[tex]V_1 = 2ft^3[/tex]
For cuboid 2
[tex]V_2 = 4 * 4 * 4[/tex]
[tex]V_2 = 64ft^3[/tex]
Amount of plaster is then calculated as:
[tex]Amount = V_1 + V_2[/tex]
[tex]Amount = 2ft^3 + 64ft^3[/tex]
[tex]Amount = 66ft^3[/tex]

Answer:
81/x - 3 = 6 2x - 3 = 15Answer:
it's only the last two
Step-by-step explanation:
3x + 2 = 25
3x + 2 - 2 = 3x
25 - 2 = 23
3x = 23
3x / 3 = x
23 / 3 = 7 2/3
x = 7 2/3 not this one
x/3 + 7 = 8
x/3 + 7 - 7 = x/3
8 - 7 = 1
x/3 = 1
x/3 * 3 = x
1 * 3 = 3
x = 3 not this one
4 + 5x = 18
4 + 5x - 4 = 5x
18 - 4 = 14
5x = 14
5x / 5 = x
14 / 5 = 2 4/5 not this one
24 - 2x = 13
24 - 2x - 24 = -2x
13 - 24 = -11
-2x = -11
-2x / -2 = x
-11 / -2 = 5 1/2 not this one
81/x - 3 = 6
81x - 3 + 3 = 81/x
6 + 3 = 9
81/x = 9
81/x * x = 81
9 * x = 9x
81 = 9x
81 / 9 = 9
9x / 9 = x
9 = x this one
2x - 3 = 15
2x - 3 + 3 = 2x
15 + 3 = 18
2x = 18
2x / 2 = x
18 / 2 = 9
x = 9 this one

Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct _____ because it _____.
a. an effect size estimate; tells the researcher the number of participants needed for trustworthy results
b. alpha testing; determines how meaningful the study results will be
c. a statistical significance; determines how meaningful the study results will be
d. a power analysis; tells the researcher the number of participants needed for trustworthy results
Answer:
d. a power analysis; tells the researcher the number of participants needed for trustworthy results.
Step-by-step explanation:
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.
Before hypothesis testing and at the beginning of a study, a researcher is advised to conduct a power analysis because it tells the researcher the number of participants needed for trustworthy results.
A power analysis should always be conducted before the collection of data because it will help you as a researcher to determine the smallest sample size that's accurate enough to detect the effect of a specific test at the desired statistical significance level.

rewrite 2 x 2^4 as an expression as a single power
If you're wanting it alone just with the exponents, here is how you're going to do it:
Technically, the 2 alone has a power, and it's simply just one. When exponents are being used in numbers multiplying together, they add.
So, to simplify this it'd be 2^5.
If you're wanting the actual answer, you would do exponents first. Remember that exponents are just the number being multiplied by itself x times:
2 x 2 x 2 x 2 = 16
Now we just need to multiply this by 2 and you'll get 32.
OR, if you do the 2^5, you'll still get 32!

A recipe calls for 2 cups sugar to 3 cups flour. How many cups of sugar is needed for 9
cups of flour?
a.
6 cups
b. 4 cups
c. 5 cups
d 7 cups
Answer:
a) 6 cups
Step-by-step explanation:
We can use a ratio for this:
sugar : flour
2 : 3
x : 9
2 3
--- = ---
x 9
Cross multiply:
2 (9) = 3x
18 = 3x
6 = x
x = 6
To double-check, you can plug the value back into the ratio and make them fractions, then simplify to see if it gets the original amount. Here's what I'm talking about:
2 : 3
x : 9 ======> 6 : 9
[tex]\frac{6}{9} \frac{/3}{/3} = \frac{2}{3}[/tex]
THESE ARE DUE TODAY HELPPPPPP
Answer:
x = 12 and y = 31
Step-by-step explanation:
Hey There!
So the two angles with x are interior angles meaning that they are congruent
So to solve for x we use the equation
3x+17=5x-7
step 1
add 7 to each side
17+7=24
-7+7 cancels out
now we have
3x+24=5x
step 2 subtract each side by 3x
3x-3x cancels out
5x-3x=2x
were left with
2x=24
final step divide each side by 2
24/2=12
2/2 cancels out
x=12
now we plug it into one of the expressions
3x12=36
36+17=53
the angle that is equal to 53 is supplementary to the angle with y meaning that they add up to 180
so to solve for y we use this equation
180=4y+3+53
step 1 combine like terms
53+3=56
now we have
180=4y+56
step 2 subtract each side by 56
180-56=124
124=4y
step 3 divide each side by 4
124/4=31
y=31
so we can conclude that
x=12 and y = 31
