Answer:
x = 2
Step-by-step explanation:
We can find this by doing the short (and wildly incorrect way, according to teachers) way and input two in. The way the teachers want you to do it is this way:
3x + 4 = 10
3x + 4 (-4) = 10 (-4)
3x = 6
3x = 6/3
x = 2
2 is your answer.
What is the independent variable in d= 43t ?
Answer:
t (based on the information you have given)
Step-by-step explanation:
d is dependent on the equation and 43 will probably change
Answer:
43
Step-by-step explanation:
In the expression d = 43t, two variables are visible. One represents constants and the other represents the dependent variable. X is often used to represent the independent variable which is the one that is always manipulated ( I CHANGE ). The 43 represents the variable that is always changing and being manipulated. 43 represents X as it is the representing the manipulated variable.
As a single logarithm, 2log2 6- log29+ 1/3log2 27 = log2 12.
Answer:
true
Step-by-step explanation:

An amount of $17,000 is borrowed for 10 years at 4.75% interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid back?
Use the calculator provided and round your answer to the nearest dollar.
Answer:
$27,039
Step-by-step explanation:
Calculating the amount of interest :
A = P (1 + r/n)^(nt)A = interestP = principalr = rate of interest (in decimal)n = number of times compoundedt = time (in years)Given values :
P = $17,000r = 4.75% = 0.0475n = 1t = 10Solving :
A = (17,000)(1 + 0.0475/1)¹⁰A = (17,000)(1.0475)¹⁰A = (17,000)(1.59052433)A = $27,039 (nearest dollar)Based on a sample of 55 people, the sample mean GPA was 3.33 with a standard deviation of 0.08
The test statistic is:
(to 2 decimals)
The p-value is: (to 2 decimals)
Using the t-distribution, it is found that the desired measures are given as follows:
The test statistic is t = 2.78.The p-value is of 0.01.What are the hypotheses tested?At the null hypothesis, it is tested if the mean GPA of the students is of 3.3, that is:
[tex]H_0: \mu = 3.3[/tex]
At the alternative hypothesis, it is tested if the mean GPA is different than 3.3, hence:
[tex]H_1: \mu \neq 3.3[/tex].
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.The values of the parameters are given as follows:
[tex]\overline{x} = 3.33, \mu = 3.3, s = 0.08, n = 55[/tex]
Hence, the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{3.33 - 3.3}{\frac{0.08}{\sqrt{55}}}[/tex]
t = 2.78.
We are testing if the mean is different of a value, hence we have a two-tailed test. Using a t-distribution calculator, with 55 - 1 = 54 df and t = 2.78, the p-value is of 0.01.

Answer:
<B = 52°
Step-by-step explanation:
The triangle is 180° Angle A and B add up to 118°
4y° + (3y + 7)° = 112°
7y + 7 = 112°
7y = 105
y = 15
Since you solve for y, plug your y into the angles to solve.
<B = 3y + 7
<B = 3 * 15 + 7
<B = 45 + 7
<B = 52°

Function g can be thought of as a translated (shifted) version of f(x) = x2.
Write the equation for g(2).
g(x)=
If the function f(x) is translated at a point (2, 6). Then the function g(x) will be given as g(x) = (x - 2)² + 6.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Function g can be thought of as a translated (shifted) version of f(x) = x².
Then the equation of the function g(x) will be
g(x) = (x - 2)² + 6

Solve the equation by completing the square. x^2 + 12x + 36 = 0 x = [?]
Answer:
x = - 6
Step-by-step explanation:
x² + 12x + 36 = 0 ( subtract 36 from both sides )
x² + 12x = - 36
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = - 36 + 36
(x + 6)² = 0 ( take square root of both sides )
x + 6 = [tex]\sqrt{0}[/tex] = 0 ( subtract 6 from both sides )
x = - 6

What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry.
The property angle-angle-angle (AAA), is used for similar triangles. It can not be used to prove that two triangles are congruent triangles. Therefore, it is not a valid criterion.
Now, this can be proved using two triangles having the same angle measurement as 60°. The two triangles given below has the same angle measurement although, their sides have different measurement, thus, the two triangles are not equal.
Hence, the AAA property can not be used to prove if the triangles are congruent.

Answer: A triangle is a basic geometric shape. Triangle congruence cannot be established using the AAA property. A triangle is a polygon having three vertices and three edges. It is a fundamental geometric figure. For comparable triangles, the property angle-angle-angle (AAA) is employed. It cannot be used to establish the congruence of two triangles. As a result, it is an invalid standard. Now, this may be demonstrated using two triangles with angles equal to or greater than 60°. The two triangles shown below are not equal because they have different side measurements despite having the same angle measurement. The triangles' congruence cannot therefore be established using the AAA property.

named John. The probability that a student picked at random is named
something other than Stephanie or John is what out of what?
Answer:
3/4 or 15/20
Step-by-step explanation:
this is because, you know there is 3 girls named the same thing and two boys named the same thing so if you know there are 20 people in the class, you do 3g + 2b = 5/20
So the fraction is either 15/20 or 3/4 for reduced fraction.
A packaging factory is open from Monday to Saturday.
In a particular week, 15,000 packets were packed on Monday and the factory was also closed on Tuesday.
If no less than 100,000 packets should be packed in that week, what is the minimum equal number of packets that must be packed per day for the remaining days?
packets
Answer:
A minimum of 21250 packets per day.
Step-by-step explanation:
If Monday produced 15,000 packets, and Tuesday was closed they produced 15,000 packets in 2 days.
The factory is open 6 days a week.
They need 100,000 packets.
They have 15,000 packets.
6 subtract 2 is 4.
100,000 subtract 15,000 is 85,000.
They need 85,000 packets in 4 days.
That is a minimum of 21250 packets per day.
21250 is minimum equal number of packets that must be packed per day for the remaining days
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that packaging factory is open from Monday to Saturday.
On monday 15,000 packets were packed.
On tuesday the factory is closed.
The factory has to pack in that week of 100000 packets.
As already 2 days completed by packing 15000
The remaining packets should be packed within 4 days.
The remaining packets are 100000-15000
85000
This should be done with in four days of time.
We need to find the minimum equal number of packets that must be packed per day for the remaining days.
Divide 85000 by 4
85000/4
21250
Hence, 21250 is minimum equal number of packets that must be packed per day for the remaining days
