Solve for x in the diagram below.
Answer:
x=20Step-by-step explanation:
hope it will help you
Answer:
Step-by-step explanation:
x+ 2x + x +10 = 90
Combine like terms
4x + 10 = 90
To isolate 'x', first subtract 10 from both sides
4x = 90 - 10
4x = 80
Now, divide both sides by 4 to get the value of 'x'
x = 80/4
x = 20

Answer:
Step-by-step explanation:
Y-intercept is -2.
Using slope formula, 2-(-2)/2-0 = 4/2 = 2 = slope.
Plugging into slope-intercept form:
y=mx+b => y=2x-2
The floor of Taylor's bathroom is covered with tiles in the shape of triangles. Each triangle has a
height of Zin and a base of 12 in. If the floor of her bathroom has 40 tiles, what is the area of the
bathroom floor?
Answer: 1680
Step-by-step explanation: first we have to find the area of each triangle so we do 7 times 12 then divide by 2 which equals 42. then since there are 40 tiles we multiply by 40 which will equa 1680.
[tex]\begin{equation}\text { Question: If } \int_{\frac{-1}{\sqrt{2}}}^{\frac{1}{\sqrt{2}}}\left(\left(\frac{x-1}{x+1}\right)^{2}+\left(\frac{x+1}{x-1}\right)^{2}-2\right)^{\frac{1}{2}} d x\end{equation}[/tex]

(a) ln16

We want to evaluate
[tex]\displaystyle \int_{-\frac1{\sqrt2}}^{\frac1{\sqrt2}} \sqrt{\left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2} \, dx[/tex]
First we note that the integrand is even (replacing x with -x doesn't fundamentally alter the function being integrated), so this is equal to
[tex]\displaystyle 2 \int_0^{\frac1{\sqrt2}} \sqrt{\left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2} \, dx[/tex]
The radicand reduces significantly to
[tex]\displaystyle \left(\frac{x-1}{x+1}\right)^2 + \left(\frac{x+1}{x-1}\right)^2 - 2 = \frac{16x^2}{(1-x^2)^2}[/tex]
so that taking the square root, we simplify the integral to
[tex]\displaystyle 8 \int_0^{\frac1{\sqrt2}} \frac x{1-x^2} \, dx[/tex]
which is trivially computed with a substitution of [tex]y = 1 - x^2[/tex] and [tex]dy=-2x\,dx[/tex]:
[tex]\displaystyle -4 \int_1^{\frac12} \frac{dy}y = 4 \int_{\frac12}^1 \frac{dy}y = -4 \ln\left(\frac12\right) = \ln(2^4) = \boxed{\ln(16)}[/tex]

Step-by-step explanation:
To find 1/4 of 1500, you must divide the number by the denominator of the fraction.
1500 ÷ 4 = 375
For the given equation, find the value of M when x=3. 2x+m=7
[tex]m = 1[/tex]
Step-by-step explanation:
[tex]2x + m = 7[/tex]
insert x=3 into the equation
[tex]2(3) + m = 7[/tex]
multiply
[tex]6 + m = 7[/tex]
subtract 6 on both sides
[tex]6 - 6 + m = 7 - 6[/tex]
[tex]m = 7 - 6[/tex]
simplify
[tex]m = 1[/tex]

After a product recall, a company solicits feedback from a random sample of 100 customers regarding their opinion about the company since the recall. Customers were asked, "Do you approve, disapprove, or have no opinion about the company?” The public relations department is concerned that the opinions may be equally distributed across these three options. The survey reveals that 38 customers approve, 45 disapprove, and 17 have no opinion. They decide to carry out a test of significance to determine if there is convincing evidence that the distribution of opinion in the population is equally distributed across the three options. What is the value of the chi-square test statistic and the P-value of this test?
Find the chi-square table here.
χ2 = 7.77, P-value is between 0.02 and 0.025
χ2 = 7.77, P-value is between 0.05 and 0.10
χ2 = 8.54, P-value is between 0.01 and 0.02
χ2 = 8.54, P-value is between 0.025 and 0.05
The value of the chi-square test statistic and the P-value of this hypothesis test is χ2 = 7.77, P-value is between 0.02 and 0.025.
How to depict the hypothesis?It should be noted that hypothesis testing is done in order to get more information about a particular issue.
In this case, the value of the chi-square test statistic and the P-value of this hypothesis test is χ2 = 7.77, P-value is between 0.02 and 0.025.
This illustrates that there's convincing evidence that the distribution of common opinion is note equally distributed across the three options.

a die and a coin is rolled and tossed respectively.what is the probability of getting a five and a tail ?
Answer:
1/12
THIS DESERVES BRAINLISTTT
Step-by-step explanation:
There are 12 possible outcomes, 6 for the die for each of the 2 for the coin. Only one comprises a 5 and a tail so the probability, assuming a fair coin and die, is 1/12.
A die has 6 sides. A coin has two.
The probability of rolling a 5 on the die is 1/6.
The probability of getting tails is 1/2.
To get the combined probability, we must multiply the two together. This gives us a total probability of 1/12.
The probability of rolling a 5 and getting tails is 1/12.

Slope Equations
What is the equation of the line that passes through the point (0,-4) and has a slope of 5?
y = 5x – 4
y= - 4x – 5
y= -5x +4
y=2x - 4
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = slopeb = y-intercept (the value of y when x=0)Solving the QuestionWe're given:
m = 5The line passes through the point (0,-4)Because the slope of the line is 5, we know that the m value in y=mx+b has to be 5. This rules out all the options except for the first, which is the only equation in which the m vaue is 5.
On top of that, we know that the y-intercept occurs when x=0. Given that the line passes through the point (0,-4), we know that the y-intercept is -4.
The equation in the first option tells us this as well, as it has -4 as the b value in y=mx+b.
Answery = 5x - 4

The equation of the graph G(x) is (x - 4)^2 + 1.
We have given the graph below have the same shape.
We have to find the equation of the graph g(x).
We have to find the equation of g(x) by using the phase shifting.
What is the shifting of the graph?A shift is a rigid translation in that it does not change the shape or size of the graph of the function.
Here we can see that the vertex of the graph in f(x) is (0,0) and the
vertex of the graph is g(x) is (4,1)
Therefore [tex]x^2[/tex] is replaced by [tex](x-4)^2[/tex].
and is shifted upward one unit therefore we get
[tex]G(x)=(x-4)^2+1[/tex]
Therefore we get the graph of g(x)= (x - 4)^2 + 1.
