Answer:
See explanation
Step-by-step explanation:
First, because it is a quadratic function, we know that its graph is a parabola that opens up, as x is positive. Because x has no coefficients, we also know that it is a basic parabola, with no vertical stretches or compressions, and a vertex at x=0. Because of the -3, we know the parabola has a verticle shift down 3 units, making the parabola's vertex at (0,3). Hope this helps!

Here, we need to know the concept of FOIL.
It is a way to expand squared or greater exponents parenthesis.
F irstO uterI nner L astStep-by-step explanation:
Given information
x² + y² = 20
xy = 7
Given expression
(x - y)²
Expand parenthesis through FOIL
= (x - y) (x - y)
= x · x - x · y - x · y + y · y
= x² - 2xy + y²
Substitute values into the expression
= x² + y² - 2xy
= (20) - 2 (7)
= 20 - 14

Based on the relationship between the independent variable x and dependent variable y above, Leia believes that the domain is {1, 4, 7, 10, 13, 16, 19} and the range is {4, 7, 10, 16, 19, 22}. Is Leia correct? If not, determine Leia's error, and state the correct domain and/or range.
Answer:
Leia is incorrect; 10 should not be in the domain.
Step-by-step explanation:
the domain is x, the range is y. The domain really should be '1, 4, 7, 13, 16 ,19' and the 10 should not be there.
Solve the inequality.
4│x + 5│ - 2 ≤ 10
Step-by-step explanation: To solve this absolute value inequality,
our goal is to get the absolute value by itself on one side of the inequality.
So start by adding 2 to both sides and we have 4|x + 5| ≤ 12.
Now divide both sides by 3 and we have |x + 5| ≤ 3.
Now the the absolute value is isolated, we can split this up.
The first inequality will look exactly like the one
we have right now except for the absolute value.
For the second one, we flip the sign and change the 3 to a negative.
So we have x + 5 ≤ 3 or x + 5 ≥ -3.
Solving each inequality from here, we have x ≤ -2 or x ≥ -8.

23°
Step-by-step explanation:
243° + 94° + b = 360°
337 + b = 360
337 - 337 + b = 360 - 337
b = 23°

In an effort to make childrenâs toys safer and more tamperproof, toy packaging has become cumbersome for parents to remove in many cases. Accordingly, the director of marketing at Toys4Tots, a large toy manufacturer, wants to evaluate the effectiveness of a new packaging design that engineers claim will reduce customer complaints by more than 10 percentage points. Customer satisfaction surveys were sent to 220 parents who registered toys packaged under the old design and 220 parents who registered toys packaged under the new design. Of these, 81 parents expressed dissatisfaction with packaging of the old design, and 41 parents expressed dissatisfaction with packaging of the new design.
Let p1 represent the population proportion of parents that expressed dissatisfaction with the packaging of the old design and p2 represent the population proportion of parents that expressed dissatisfaction with the packaging of the new design.
Required:
a. Specify the null and alternative hypotheses to test for whether the proportion of customer complaints has decreased by more than 5% under the new packaging design.
b. What is the value of the test statistic and the associated p-value?
c. At the 1% significance level, do the results support the engineers' claim?
d. At the 10% significance level, do the results support the engineers' claim?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Old design samples(n1) = 220
New design samples (n2) = 220
P1 = 81/220 = 0.368 ; P2 = 41/220 = 0.186
Null hypothesis : p1 - p2 ≥ 0.05
Alternative hypothesis : p1 - p2 < 0.05
Using the test statistic formula :
t = (P1 - P2) / √[P(1-P)(1/n1 + 1/n2)]
P = (81 + 41)/(220 + 220) = 122/440 = 0.277
1 - P = 0.723
t = (0.368 - 0.186) / (√(0.277(0.723)(1/220 + 1/220)))
t = 4.265
P value from z test at α = 0.05
P value = 0.00002
Test for significance at α = 0.01 ;
Test for significance at α = 0.1
Result is significant at both α levels, hence reject the Null.

The number of minutes that Samantha waits to catch the bus is uniformly distributed between 0 and 15 minutes. What is the probability that Samantha has to wait less than 4.5 minutes to catch the bus
Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.
What is the uniform probability distribution?It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
[tex]P(X < x) = \frac{x - a}{b - a}[/tex]
In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.
The probability that Samantha has to wait less than 4.5 minutes to catch the bus is given by:
[tex]P(X < 4.5) = \frac{4.5 - 0}{15 - 0} = 0.3[/tex]

an insect is 3.5 millimeters long which expression finds the length of the insect in decimeter
Answer:
0.035 decimeters.
Step-by-step explanation:
Answer:
The length of the insect in decimeters is 0.035.
Step-by-step explanation:
Conversion of unit questions can be solved by rule of three.
Each millimeter has 0.01 decimeter. How many decimeters are there in 3.5 millimeters? So:
1 ml - 0.01dm
3.5ml - x dm
The length of the insect in decimeters is 0.035.

3y-2=10
Step-by-step explanation:
Given;
Which of the following does Not belong to the group?
2x > 5 - x
3(x-4) [tex]\leq[/tex] -23
3y - 2 = 10
a < 13a + 1
Solve;
Base on the given data, we can infer that "3y-2=10" does Not belong to the group. You can see that other have Python. Python has six comparison operators: less than ( < ), less than or equal to ( <= ), greater than ( > ), greater than or equal to ( >= ), equal to ( == ), and not equal to ( != ). While, "3y-2=10" doesn't have one.
As well as if you simplify/solve these other will be given as a fraction while "3y-2=10" answer is a whole number.
Solution of each given answer choice;
2x > 5 - x
Add x to both sides
2x + x > 5 - x + x
Simplify
3x > 5
Divide both sides by 3
[tex]\frac{3x}{3} > \frac{5}{3}[/tex]
x[tex]x=\frac{5}{3}[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3 ( x - 4) [tex]\leq[/tex] - 23

Divide both sides by 3
[tex]\frac{3\left(x-4\right)}{3}\le \frac{-23}{3}[/tex]
Simplify
[tex]x-4\le \:-\frac{23}{3}[/tex]
Add 4 to both side
[tex]x-4+4\le \:-\frac{23}{3}+4[/tex]
Simplify
x [tex]\leq -\frac{11}{3}[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3y-2 = 10
Add 2 to both sides
[tex]3y-2+2=10+2[/tex]
Simplify
[tex]3y=12[/tex]
Divide both sides by 3
[tex]\frac{3y}{3}=\frac{12}{3}[/tex]
Simplify
y = 4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
a>13a+1
[tex]a > 13a+1\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:a < -\frac{1}{12}\:\\ \:\mathrm{Decimal:}&\:a < -0.08333\dots \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-\frac{1}{12}\right)\end{bmatrix}[/tex]
Subtract 13a from both sides
[tex]a-13a > 13a+1-13a[/tex]
Simplify
[tex]-12a > 1[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-12a\right)\left(-1\right) < 1\cdot \left(-1\right)[/tex]
Simplify
[tex]12a < -1[/tex]
Divide both sides by 12
[tex]\frac{12a}{12} < \frac{-1}{12}[/tex]
Simplify
[tex]a < -\frac{1}{12}[/tex]
Hence, Now you can infer that "3y-2=10" does not belong to the group.

Answer:

Step-by-step explanation:
First, we have to make our 2 fractions denominators the same to be able to subtract them! We want both of our denominators to be 8 so 5/8 already had 8 so we just need to change 1/2 to do that we are going to multiply the fraction by 4 so 1 x 4 = 4/2 x 4 = 8. Now we have 5/8 and 4/8. All we need to do now is subtract our fractions! 5/8 - 4/8 = 1/8
