Answer:
x = 7
Step-by-step explanation:
x + 4 > 2x - 3
x by itself = 1x
1x + 4 > 2x - 3
Subtract 1x
1x - 1x + 4 > 2x - 1x -3 =
4 > 1x -3
Add 3
4 + 3 > 1x -3 +3 =
7 > 1x
1x is the same as x
7 = x

How do I Invert 6/7? Please help me because I am confused!
Answer:
The invert part of “invert and multiply” means to take the denominator of this big fraction, 1/4, and invert it. In other words, flip it on its head so its numerator becomes its denominator and vice versa. The inverse of 1/4 is therefore 4/1, or just 4.

Jonathan will run a 614-mile relay with 4 other team members, where each team member runs an equal distance. How many miles will Jonathan run?
Answer: Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .
Step-by-step explanation:
Given: Total distance to run =[tex]6\dfrac14[/tex] miles [tex]=\dfrac{25}{4}[/tex] miles
Total members = 1+4 = 5
if each member runs equal distance.
Then, each member will run = [tex]\dfrac{\text{Total distance}}{\text{Total members}}[/tex]
[tex]=\dfrac{\dfrac{25}{4}}{5}\\\\ \lim_{n \to \infty} a_n =\dfrac{25}{4\times5}\\\\=\dfrac{5}{4}\\\\ = 1\dfrac14 \text{miles}[/tex]
Hence, Jonathan will rum [tex]1\dfrac14\text{ mile}[/tex] .
What is the slope of the line with equation y-3=- 7(x-2)?
Answer:
-7
Step-by-step explanation:
Remember y = mx + b and m is the slope. Just convert to this form and identify the m.
y-3=- 7(x-2)
y - 3 = -7x + 14
y = -7x + 17

Since 1/2 slope is perpendicular to the equation the slope is -2 which is the opposite of the reciprocal of 1/2.
Since the slope is -2, every time you go forward you go down 2.
(-1, 0)
(0, -2)
The y-intercept is -2.
y = mx + b
y = -2x - 2
The answer is B
The student scores on a history test are normally distributed with an unknown population mean and standard deviation A random sample of 38 scores is taken and results in a sample mean of 85 points and sample standard deviation of 4 points. dr 0,10 0.0 0.025 0.01 0.005 3 1.306 1.690 2.030 2.438 2.724 1.306 1.688 2.028 2.434 2.719 1.305 1687 2.026 2.431 2.715 1.304 1.686 2.024 2.429 2.712 1.304 1685 2.023 2.426 2.708
Find a 90% confidence interval estimate for the population mean using the Student's distribution . Round the final answers to two decimal places.
Answer:
The 90% confidence interval = (83.9, 86.1)
Step-by-step explanation:
The formula for confidence interval =
Mean ± z × standard deviation/√n
From the question:
n = 38
Mean = 85 points
Standard deviation = 4 points
Z score for 90% confidence interval = 1.645
85 ± 1.645 × 4/√38
85 ± 1.067416951
Confidence Interval =
85 - 1.067416951
= 83.932583049
≈ 83.9
85 + 1.067416951
= 86.067416951
≈ 86.1
Therefore, the 90% confidence interval = (83.9, 86.1)

Which are true if figure DEFG is reflected across the x-axis? Check all that apply.
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from G' to the x-axis will equal 2 units.
The perpendicular distance from D' to the x-axis will equal 8 units.
The orientation will be preserved.
Answer:
A,B,C
Step-by-step explanation:
If figure DEFG is reflected across the x-axis, the correct statements are:
D(0, 4) → D'(0, –4)
E(–2, 0) → E'(–2, 0)
The perpendicular distance from D' to the x-axis will equal 8 units.
Options A, B, and E are the correct answers.
What is a reflection?There are two ways of reflection.
Along x-axis:
(x, y) – (x, -y)
Along y-axis:
(x, y) - (-x, y)
We have,
D(0, 4) → D'(0, –4) - True.
Reflecting a point across the x-axis negates its y-coordinate.
E(–2, 0) → E'(–2, 0) - True.
Reflecting a point across the x-axis does not change its x-coordinate.
The perpendicular distance from G' to the x-axis will equal 2 units. - False. The perpendicular distance from G' to the x-axis will be the same as the perpendicular distance from G to the x-axis.
The perpendicular distance from D' to the x-axis will equal 8 units. - True.
The perpendicular distance from D' to the x-axis will be the same as the perpendicular distance from D to the x-axis, which is twice the distance between D and the x-axis.
The orientation will be preserved. - False.
Reflecting a figure across the x-axis will reverse the orientation of the figure.
Thus,
D(0, 4) → D'(0, –4) - True
E(–2, 0) → E'(–2, 0) - True
The perpendicular distance from D' to the x-axis will equal 8 units. - True.

Answer:
40 words
Step-by-step explanation:
120 words/3 minutes is the same as 120 divided by 3
so, you divide 120 by 30 and you get 40 words per minute
Answer:
Step-by-step explanation:
We are going to make a questioning. Look:
If in 3 minutes she can type 120 word
In 1 min how many will she type X
We adopt X as a thing witch we don't know. This forms a Rule of three. It happens when we have got 3 values but miss us 1 yet.
Generraly you'll sort the values by type. In this case, I put minutes under minute and words under words.
A Fast way to solve is: multiply where there is not an incognt (1*120) and divide by what left (3)
So:
1*120=120
Divided by 3 (120/3) it's equals 40 words per minute.

A fireman spots a stranded woman in the window of a 200-foot tall office building. From the
point where the fireman is standing, the angle of elevation to the stranded woman is 42° 33'
and to the top of the building is 58° 6'. How far from the ground is the stranded woman?
Answer:
114.3 foot
Step-by-step explanation:
Height of building,h=200 foot
Let BC=x
[tex]tan\theta=\frac{perpendicular\;side}{base}[/tex]
Using the formula
[tex]tan(58^{\circ} 6')=\frac{200}{CD}[/tex]
[tex]CD=\frac{200}{tan(58^{\circ} 6')}[/tex]
[tex]CD=124.5 foot[/tex]
Now,
[tex]\frac{BC}{CD}=tan(42^{\circ}33')[/tex]
[tex]\frac{x}{124.5}=0.9179[/tex]
[tex]x=124.5\times 0.9179[/tex]
[tex]x=114.3 foot[/tex]
Hence, the distance of woman from the ground=114.3 foot
The ground is 123.24 ft far from the stranded woman.
Given the total height of the office building is 200 ft.
And the angle of elevation of the top of the building is 58° 6' and the angle of elevation to the stranded woman is 42° 33'.
We know that, from trigonometric ratios,[tex]tan \theta =\frac{perpendicular}{base}[/tex]
here [tex]\theta[/tex] is the angle of elevation of the top of the building from the fireman.
Now, [tex]tan ( 58^{0} 6')[/tex][tex]=\frac{200}{base}[/tex]
[tex]1.488=\frac{200}{base}[/tex]
[tex]base=\frac{200}{1.488}[/tex]
[tex]base=134.40[/tex] ft
Now the woman is stranded in the window of the building say at the height of h ft, and the angle of elevation of the woman from the fireman is 42° 33'.
So, [tex]tan (42^{0} 33')[/tex][tex]= \frac{perpendicular}{base}[/tex]
[tex]tan(42^{0} 33' )= \frac{h}{134.40}[/tex]
[tex]0.917=\frac{h}{134.40}[/tex]
[tex]0.917\times134.40=h[/tex]
[tex]h=123.24 ft[/tex]
Hence the ground is 123.24 ft far from the stranded woman.

The overall length is the sum of the constituent segment lengths, so ...
FG + GH = FH

x +17 = 2x +26
x -9 = 2x
-9 = x

Check
Then the segment length FG is ...
10 +x = 10 -9 = 1
and the overall length is ...
2x +26 = 2(-9) +26 = -18 +26 = 8
