Answer:
The lower class limit of the first class is 40
Step-by-step explanation:
Given
See attachment for histogram
Required
The lower limit of the first class
The attached histogram has overlapping interval, and the intervals are:
40 to 60, 60 to 80, 80 to 100, and so on....
The first class here is:
40 to 60
As a general rule; a class is represented by Lower Limit to Upper Limit.
So, by comparison.

Given:
The equation is:
[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]
To find:
The value of y.
Solution:
We have,
[tex]\dfrac{y}{p-q}=\dfrac{y}{p+q}[/tex]
On cross multiplication, we get
[tex]y(p+q)=y(p-q)[/tex]
[tex]yp+yq=yp-yq[/tex]
[tex]yp+yq-yp+yq=0[/tex]
[tex]2yq=0[/tex]
Dividing both sides by 2q, we get
[tex]\dfrac{2yq}{2q}=\dfrac{0}{2q}[/tex]
[tex]y=0[/tex]
Therefore, the correct option is A.

What are two step equations that equal 17?
Answer:
5x+7=17
Step-by-step explanation:
5x+7=17
-7 -7
----------------
5x=10
5 5
x=2
5(2)+7=17
10+7=17
17=17
The two step equations that equal 17 are:
1) 3x + 5 = 17
2) 2y - 8 = 17
The two examples of two-step equations that equal 17:
1) 3x + 5 = 17
To solve this equation, we subtract 5 from both sides:
3x + 5 - 5 = 17 - 5
3x = 12
Finally, we divide both sides by 3:
3x/3 = 12/3
x = 4
So the solution to the equation is x = 4.
2) 2y - 8 = 17
To solve this equation, we add 8 to both sides:
2y - 8 + 8 = 17 + 8
2y = 25
Next, we divide both sides by 2:
2y/2 = 25/2
y = 12.5
So, the solution to the equation is y = 12.5.

An advertising company charges $40 per half-page advertisement and $75 per full-page advertisement
Michael has a budget of $800 to purchase 13 advertisements.
(a) Define a variable for each unknown
Write a system of equations to represent the situation and solve the system
(b) How many half-page advertisements does Michael purchase?
Show your work.
(c) How many full-page advertisements does Michael purchase?
Answer:
F=full page H=half page
40H+75F=800
H+F=13 so H= 13-F substitute 13-F for H in the first equation.
40(13-F)+75F=800
520-40F +75F=800
35F= 280 so F=280/35=8
8 fullpage and 5 halfpage ads

Answer:
m∠ZWX = 105°
Step-by-step explanation:
Properties of a kite,
1). One diagonal of a kite bisects at least one pair of opposite angles.
2). Diagonals of a kite kite are perpendicular to each other.
In ΔWTZ,
m∠WZT = [tex]\frac{1}{2}(m\angle WZY)[/tex]
= [tex]\frac{1}{2}(100)[/tex]
= 50°
m∠WTZ = 90° [By second property]
m∠WZT + m∠WTZ + m∠ZWT = 180°
50° + 90° + m∠ZWT = 180°
m∠ZWT = 180° - 140°
= 40°
Similarly, in ΔWTX,
[tex]m(\angle WXT)=\frac{1}{2}(m\angle WXY)[/tex]
m(∠WXT) = [tex]\frac{1}{2}(50)[/tex]
= 25°
m(∠WTX) = 90°
m∠WTX + m∠WXT + m∠TWX = 180°
90° + 25° + m∠TWX = 180°
m∠TWX = 180° - 115°
= 65°
Since, m∠ZWX = m∠ZWT + m∠TWX
Therefore, m∠ZWX = 40° + 65°
= 105°
Solve n - 24 = 28. Be sure to show all work.
Answer:
n= 52
Step-by-step explanation:
n= 28+24
n= 52
Hello
Answer:
n=52
Step-by-step explanation:
n-24=28
n=24+28
n=52
You solve n by adding 24 to both sides to get n by itself which is n= 24+28. After you add 24 and 28 together you get 52. So n=52.

g is a trigonometric function of the form g(x)=a sin (bx+c)+d.
The function intersects its midline at (-1 , 6) and has a minimum point at (-3.5 , 3)
Find a formula for g (x). Give an exact expression.
Answer:
Formula for g(x) is [tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]
Step-by-step explanation:
Given - g is a trigonometric function of the form g(x)=a sin (bx+c)+d. The function intersects its midline at (-1 , 6) and has a minimum point at (-3.5 , 3)
To find - Find a formula for g (x). Give an exact expression.
Proof -
Given that,
g(x)=a sin (bx+c)+d
We know that, Midline is present in between maximum and minimum
Here given that, minimum is present is 3 and midline is present at 6
So, Maximum occurs at 9.
Now,
We know that,
Standard form of sine function is - g(x) = Asin(B(x-C)) + D
Where
A = Amplitude
and Amplitude = (Maximum - minimum) / 2
= (9 - 3)/ 2
= 6/2 = 3
⇒A = 3
Now,
Period = [tex]\frac{2\pi }{B}[/tex]
⇒B = (2π) / Period
= (2π) / 10
= π/5
⇒B = π/5
Now,
Phase Shift : C = -1 ( i.e. 1 to the left)
Vertical Shift : D = 6
So,
We get
g(x) = Asin(B(x-C)) + D
= [tex]3 sin(\frac{\pi }{5}(x -(- 1))) + 6[/tex]
⇒[tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]
∴ we get
Formula for g(x) is [tex]g(x) = 3 sin(\frac{\pi }{5}x + \frac{\pi }{5} ) + 6[/tex]

The scatter plot suggests a relationship between time and the distance from the destination. The equation of the line of best fit is y=-0.6x+15, and the correlation coefficient is -0.8. Which best describes the correlation between the two variables?
a. weak positive
b. strong positive
c. weak negative
d. strong negative
Answer:
Strong Negative
Step-by-step explanation:
We already know that the answer is between c and d because the correlation coefficient negative.
We just have to figure out whether it is strong or weak.
In general, anything between -.7 and -1 is considered to have a strong correlation. -.8 is in between -.7 and -1 therefore the correlation is best described as strong negative.

If y varies directly as x and y = 64 when x = 16, what is the value of y when x = 12 ?
Answer: Y=48
Y is 4 times more than x. If x=12, y=48. Notice in the first part of the question, if you divide 64 by 4, you get 16. This means in order to get your answer, you must mulitiply x by 4 to get y. 12x4=48.
