Answer:
(2/3, 13/3) (Exactly one solution)
Step-by-step explanation:
Write these equations in a column:
x+y=5
2x-y=-3
Note that we can eliminate y immediately by adding these two equations together. We get:
3x = 2, so that x = 2/3.
Substituting 2/3 for x in the first equation, we get:
2/3 + y = 5. Clear out fractions by multiplying all three terms by 3:
2 + 3y = 15, or 3y = 13. Then y = 13/3, and the solution is
(2/3, 13/3) There is exactly one solution.

A dot plot would show 7 points for numbers greater than 2.
The intervals on a histogram should be 0 to 2, 3 to 4, and 5 to 6.
A histogram would have a maximum of 7 bars.
A histogram should not show a bar that includes 0 pieces of mail.
Answer:
B) A dot plot would show 7 points for numbers greater than 2.
D) A histogram would have a maximum of 7 bars.
Step-by-step explanation:
quiz on edg told me ;)
The true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.
What is a Dot Plot and a Histogram?A dot plot uses dots to show each data point, while for histogram, the frequency for the data values are depicted by bars or bins.
In the data ste given, 7 of the data points are greater than 2. So, the dot plot for the data distribution would display 7 points for values greater than 2.
Also, there are 7 different values, which are from 0 - 6. This will require 7 bars if we want to represent the data on a histogram.
Therefore, the true statements are:
B. dot plot would show 7 points for numbers greater than 2.
D. histogram would have a maximum of 7 bars.

What is m equal to?
Answer:
Step-by-step explanation:
I can help
Step 1
0.8(m - 5) = 10 Simplify
Step 2
0.8(m - 5) = 10 simplify the equation
0.8m-4=10
Step 3
0.8m-4=10 Add 4 to the sides

ABCD is an isosceles trapezoid.
measure of angle b=
measure of angle d=
measure of angle c=
Answer:
∡b = 53°
∡d = 127°
∡c = 127°
Step-by-step explanation:
in trapezoids, the two top angles are equal and the two bottom are equal
also, there are 360 degrees in any 4-sided polygon
53 + 53 + x + x = 360
2x + 106 = 360
2x = 254
x = 127

A survey found that women's heights are normally distributed with mean 63.7 . And standard deviation 3.7 . The survey also found that men's heights are normally distributed with mean 67.5. And standard deviation 3.7. Consider an executive jet that seats six with a doorway height of 56.4. Complete parts (a) through (c) below.
Complete question :
A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.
1-What percentage of adult men can fit through the door without bending?
2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below
A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.
B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.
C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.
Answer:
A.) 0.135%
B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.
C.)
Step-by-step explanation:
Percentage of adult men that can fit the door without bending :
Obtain the Zscore :
Mean height of men, m = 67.5
Standard deviation, s = 3.7
Zscore = (x - m) / s ; where x = 56.4
Zscore = (56.4 - 67.5) / 3.7
Zscore = - 11.1 / 3.7
Zscore = - 3
P(Z < - 3) = 0.0013499 (Z probability calculator)
P(Z < - 3) = 0.0013499 * 100% = 0.13499%
Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric functions. Sketch a triangle in the correct quadrant and label.
sec θ= 17/15
sin θ<0
Answer: See step by step. Replace the x with theta
Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.
We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.
We can find tangent by using the identity
[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.
[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]
[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]
[tex]tan^{2}(x)=\frac{64}{225}[/tex]
tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth quadrant is negative so the answer is instead
[tex]tan x= -\frac{8}{15}[/tex]
We can find cotangent by taking the recipocial of tan so
[tex]cot=-\frac{15}{8}[/tex]
We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is
[tex]cos =\frac{15}{17}[/tex]
We can find sin by doing quoteint identies.
[tex]\frac{sin x}{cos x} =tan x[/tex]
[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]
[tex]sin x= -\frac{8}{17}[/tex]
To find csc, take reciprocal of sine.
[tex]csc=\frac{-17}{8}[/tex]
Please help, I'm having a hard time with this ;-;
Answer:
A
Step-by-step explanation:
3 times steep means slope is 3 times
slope=4
new slope =3×4=12
translated 7 down means y intercept-7=1-7=-6
so new eq. is y=12x-6
Answer:
A
Step-by-step explanation:
So we know that the slope is 4, and we want to make it 3 times as steep, so that would be 12. The y-intercept is one and we want to move it down 7 units, 6-7= -1. So our final answer would be y= 12x-6!

The equation of the line A is 3x+2y=10.line B is parallel to line A and passes through the points (4,6).find the equation of the line B.
Answer: [tex]y=-\frac{3}{2}x+12[/tex]
Step-by-step explanation:
To find the equation of line B, we need to find the slope first, then the y-intercept. We first want to convert line A into slope-intercept form, so we can find the slope.
[tex]3x+2y=10[/tex] [subtract both sides by 3x]
[tex]2y=10-3x[/tex] [divide both sides by 2]
[tex]y=5-\frac{3}{2}x[/tex]
With the slope-intercept form of line A, we can see that the slope is [tex]-\frac{3}{2}[/tex]. We take the slope and the given point (4,6) to find the y-intercept of line B.
[tex]y=-\frac{3}{2}x+b[/tex] [plug in (4,6)]
[tex]6=-\frac{3}{2}(4)+b[/tex] [multiply]
[tex]6=-6+b[/tex] [add both sides by 6]
[tex]b=12[/tex]
With the y-intercept, we know the equation for line B is [tex]y=-\frac{3}{2}x+12[/tex].

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x
