Isaiah is starting his own gardening business. Isaiah thinks he can charge $15.50 per hour. If he knows he
will only be able to work 140 hours per month (that's 35 hours per week), how much money will he earn
each month?
Answer:
About $1627.5
Step-by-step explanation:
15.50 x 35 = 542.5
542.5 x 3 (the amount of weeks in a month) = $1627.5
The following data represent the monthly phone use, in minutes, of a customer enrolled in a fraud prevention program for the past 20 months. The phone company decides to use the upper fence as the cutoff point for the number of minutes at which the customer should be contacted. what is the cutoff point?321 474 461 548406 464 517 311534 425 377 505322 435 410 513499 354 307 363The cutoff point is ____minutes( round to the nearest minute)
Answer:
The answer is "717.25 minutes".
Step-by-step explanation:
In this question first, we arrange the value in ascending order that are:
307,311,321,322,354,363,377,406,425,435,461,464,474,499,505,513,517,534,548
The median is always in an orderly position that is [tex]= \frac{(n+1)}{2}[/tex].
[tex]\to \frac{(n+1)}{2} = \frac{(20+1)}{2} = 10.5[/tex] position orders
[tex]10^{th} \ and \ 11^{th}[/tex] place an average of observations so, the
[tex]Average = \frac{(425 +435)}{2} = \frac{(860)}{2} =430[/tex]
Because as medium stands at 10.5 that median is as below 10 are greater than the level.
[tex]Q_1[/tex] often falls throughout the ordered BELOW average is [tex]= \frac{(n+1)}{2}[/tex] place.
[tex]\to \frac{(n+1)}{2} = \frac{(10+1)}{2} = 5.5^{th}[/tex]ordered position
Average [tex]5^{th} \ and \ 6^{th}[/tex] location findings
[tex]Q_1 = \frac{(354+363)}{2} = \frac{(717)}{2}= 358.5[/tex]
In [tex]= \frac{(n+1)}{2}[/tex] the ordered place, Q3 always falls ABOVE the median.
[tex]\to \frac{(n+1)}{2} = \frac{(10+1)}{2} = 5.5^{th}[/tex] ordered At median ABOVE
Consequently [tex]Q_3[/tex] falls between [tex]5^{th} \ and \ 6^{th}[/tex] ABOVE the median position
[tex]15^{th}\ and \ 16^{th}[/tex]place average of observations
[tex]\to Q_3 = \frac{(499+505)}{2}=\frac{(1004)}{2} = 502[/tex]
[tex]\to IQR = Q_3 - Q_1= 502-358.5= 143.5[/tex]
[tex]\to \text{Upper fence} = Q_3 + 1.5 \times IQR= 502 + 1.5 \times 143.5 = 717.25[/tex]
If sin theta = -2/3 which of the following are possible?
Answer:
a
Step-by-step explanation:
The possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.
What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The trigonometric function, sin θ = -2/3
We know that [tex]sin \theta = \frac{opposite}{hypotenuse}[/tex]
So, opposite = -2, hypotenuse = 3
The other side of the right triangle adjacent side can be found by using the Pythagoras theorem,
[tex]adjacent=\sqrt{hypotenuse^{2} -opposite^{2} }[/tex]
⇒ [tex]adjacent=\sqrt{3^{2} -(-2)^{2} }[/tex]
⇒ [tex]adjacent=\sqrt{9-4 }[/tex]
⇒ [tex]adjacent=\sqrt{5}[/tex]
Now, [tex]cos \theta = \frac{adjacent}{hypotenuse}[/tex] and [tex]tan \theta = \frac{opposite}{adjacent}[/tex]
Then, [tex]cos \theta = \frac{\sqrt{5} }{3}[/tex]
[tex]sec \theta = \frac{1}{cos \theta}[/tex]
⇒ [tex]sec \theta = \frac{1}{\frac{\sqrt{5} }{3} }[/tex]
⇒ [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex]
[tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex]
Hence we can conclude that the possible trigonometric function is option (C) [tex]sec \theta = \frac{3}{\sqrt{5} }[/tex] and [tex]tan \theta = \frac{-2}{\sqrt{5} }[/tex] is the correct answer.

Answer:
the answer is:
a=-2
b=-4
Step-by-step explanation:
Shape P is translated to shape Q using vector [tex]\left[\begin{array}{ccc}2\\4\end{array}\right][/tex].
What is translation of a graph?"A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other."
Given, the shape P is mentioned on the graph.
Now, shape P is translated to shape Q.
Therefore, in order to reach Q from P, the shape needs to shift to the left 2.
After that the shape needs to shift downwards 4 places.
Therefore, the required vector is [tex]\left[\begin{array}{ccc}2\\4\end{array}\right][/tex].

Explain why the sum of -8 and 2 is negative, but the sum of 8 and -2 is positive.
Answer:
Adding a negitive number to a positive number is th esame as subtracting from that number.
If you have 2 and you add -8. You are really subtracting 8 from 2. 8 is bigger then 2 so your answer will be negitive. However for the second problom, 2 is less then 8 so the answer will be possitive.

Given: E is the midpoint of DF.
Prove: DE = 23
Answer:
DE=23
Step-by-step explanation:
Since E is the midpoint of DF, we know that DE and EF are equal. Thus, we can set them equal to eachother and solve.
8x-1=6x+5
2x=6
x=3
After that, plug 3 back into DE.
6(3)+5= DE
18+5= DE

y= 1/2x+ 2 to make the x the subject.
Answer:
[tex]x=2y-4[/tex]
Step-by-step explanation:
[tex]y=\frac{1}{2} x+2[/tex]
"To make x the subject" means to have the equation with all the terms in x on one side. As of now, y is the subject of the equation.
You start by subtracting 2 from both sides, you should get the following.
[tex]y-2=\frac{1}{2} x[/tex]
Then you multiply by 2 from both sides, you should end up with the following.
[tex]2(y-2)=x[/tex]
Therefore, you get the following.
[tex]x=2(y-2)[/tex]
Finally, you distribute and get the answer.
[tex]x=2y-4[/tex]
