a₁ = 10aₙ = aₙ₋₁ - 5Chang needs 245 programs for the school play on Thursday. How many boxes of programs will he need, given that each box contains 37 programs?
Answers
Let’s set up an equation to solve for x, the amount of boxes Chang needs
37x = 245
Divide both sides by 37
x = 6.62162
We can round to x = 7 boxes so that Chang will have enough programs. (Because if we say he needs 6 boxes, Chang will only have 222 programs)
3/4 + -3/8 + -1/4=?
Evaluate the expression
Answers
Answer: -1/8
Step-by-step explanation:
3/4 + -3/8 + -1/4
Find the LCM of 4, 8, and 4
That's 8 so you make an equivalent fraction for all fractions so the denominator is 8.
3/4 = 6/8
-3/8 = -3/8
-1/4 = -4/8
Now the expression looks like this:
6/8 + - 3/8 + -4/8
6/8 - 3/8 - 4/8
6/8 - 7/8

The employment status (employed or unemployed) of each individual in the U.S. workforce is a set of data that is of interest to economists, businesspeople, and sociologists. To obtain information about the employment status of the workforce, the U.S. Bureau of the Census conducts what is known as the Current Population Survey. Each month interviewers visit about 59,000 of the 98 million households in the United States and question the occupants over 14 years of age about their employment status. Their responses enable the Bureau of the Census to estimate the percentage of people in the labor force who are unemployed (the unemployment rate).
Answers
Question Completion:
(a) Identify the experimental unit.
(b) Define the population of interest to the Census Bureau.
(c) Identify the sample.
(d) What variable is being measured? Is it quantitative or qualitative?
(e) Describe the statistical inference that the economists intend to make.
Answer:
a. The experimental unit is the households visited.
b. The population of interest to the Census Bureau is all US-based individuals aged 14 and above.
c. The sample is 59,000 households.
d. The variable under measure is quantitative (percentage estimate of people in the labor force who are unemployed).
e. The economists want to make a statistical inference of the unemployed population based on the sample data analysis that they conduct.
Step-by-step explanation:
a) Data and Calculation:
Population of interest = 98 million households
Sample from population = 59,000 households
b) The unemployment rate is the percentage of the total workforce of a country that is unemployed and who may be actively seeking employment at a particular period. This implies that the unemployment rate may include persons who are active members of the workforce but may be underemployed.

Answers
Answer:
There are no solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
9m−4=−3m+5+12m
Step 1: Simplify both sides of the equation.
9m−4=−3m+5+12m
9m+−4=−3m+5+12m
9m−4=(−3m+12m)+(5)(Combine Like Terms)
9m−4=9m+5
9m−4=9m+5
Step 2: Subtract 9m from both sides.
9m−4−9m=9m+5−9m
−4=5
Step 3: Add 4 to both sides.
−4+4=5+4
0=9
Answer:
Its no solution
Step-by-step explanation:
1)Combine like terms
2)Letters with numbers in one side and only Number on the other side
3)Solve

Answers
Answer:
x = 5
<R = 47 degrees
<S = 47 degrees
<T = 86 degrees
Step-by-step explanation:
The sum of angles in a triangle is 180degrees
Given triangle RST
<R + <S + <T = 180
9x + 2 + 13x - 18 + 17x +1 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 195/39
x = 5
Get <R
<R = 9x + 2
<R = 9(5) + 2
<R = 47 degrees
Get <S
<S = 13x-18
<S = 13(5) - 18
<S = 65-18
<S = 47 degrees
Get <T
<T = 17x + 1
<T = 17(5)+1
<T = 85+1
<T = 86 degrees

I'm supposed to answer this word problem "Martin bought a television for $225. It had been on sale for 25% off. How much money did Martin save on the television because of the sale?" I want to know what equation I have to do to get the answer since I have to "show my work" I don't want an answer to the problem I just want an equation for the problem
Answers
Answer:
Martin saved $75 on the television because of the sale
Step-by-step explanation:
Equations
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x = [tex]\frac{25}{100}.x[/tex] = 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale

Find the numbers if-
A) 0.6of it is 30
B)1.5 of it is30
C)1.6 of it is 32
Answers
Answer:
(A) 18
(B) 45
(C) 51.2
Step-by-step explanation:
(A, 0.6 of 30) We need to find out 0.1 of 30 so we divide 30 by 10 which gives us 3. This means that 0.1 of 30 is 3. Since we know that, we multiply 3 by 6 which gives us 18.
(B, 1.5 of 30) Since we figured out that 0.1 of 30 is 3 on the first question, we can multiply 3 by 15 which gives us 45.
(C. 1.6 of 32) We need to find out 0.1 of 32 so we divide 32 by 10 which gives us 3.2. Now, we divide 3.2 by 16 which gives us 51.2.

Step-by-step explanation:

let,A(5,-1)

comparing it with y=mx+c

x=1
y = c = -1
now
A(5,-1) and B(1,-1)
equation of line is,
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
or, (y+1)/(x-5) = (-1+1)/(1-5)
or, (y+1)/(x-5) = 0/-4
cross multiply
-4y-4 = 0
or, 0=4y+4
or, 4y+4=0 is the required eqn

a plane, initially traveling 150 mi/hr 100 east of north, suddenly enters a region where the wind is blowing at 50 mi/hr from the southwest. What is the plane's resultant direction?
Answers
Answer:
Velocity of plane is 100 mi/hr along northeast direction
Step-by-step explanation:
From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction
since the velocity of wind and plane is exactly opposite
⇒ relative velocity of plane with respect to wind is given by
[tex]v_r_e_l = v_p - v_w[/tex] where [tex]v_p[/tex] is the velocity of plane = 150mi/hr and [tex]v_w[/tex] = velocity of wind = 50 mi/hr
Therefore, [tex]v_r_e_l = v_p - v_w[/tex] = [tex]v_r_e_l = 150 - 50 = 100 mi/hr[/tex] alond northwest direction
Therefore, velocity of plane is 100 mi/hr along northeast direction
By working with the velocity vectors, we will find that the direction of motion of the plane is 28.7 south of east.
Working with the velocity vectors:
First, we need to define our coordinate axis, I will define the x-axis as the east and the y-axis as the north.
We know that the plane travels at 150 mi/hr at 100° east of north, notice that if we measure from the positive x-axis, this is equivalent to an angle of -10°.
Then the x-component of the velocity is: 150mi/hr*cos(-10°) = 147.7 mi/hrThe y-component of the velocity is: 150mi/hr*sin(-10°) = -26 mi/hr.
So the vector is:
V = < 147.7 mi/hr, -26 mi/hr >
Now we know that the wind blowing at 50mi/hr at southwest, exactly southwest would be at an angle of 225°, so the components of the vector are:
x-component: 50mi/hr*cos(225°) = -35.4 mi/hry-component: 50mi/hr*sin(225°) = -35.4 mi/hr.So the vector is:
W = < -35.4 mi/hr, -35.4 mi/hr>
The sum of the vectors gives the total velocity of the plane in the wind, we will get:
V + W = < 147.7 mi/hr -35.4 mi/hr , -26 mi/hr -35.4 mi/hr >
V + W = <112.3 mi/hr, -61.4 mi/hr>
The direction of a vector <x, y> is given by:
θ = Atan(y/x)
Then in this case the direction of the plane is:
θ = Atan(-61.4 mi/hr/112.3 mi/hr) = -28.7°
So the direction of the plane is 28.7° south of east.
