Find the 7th term of the geometric progression which begins -6250, 1250, -250....
Answer:
a(7) = -0.4
Step-by-step explanation:
The general formula for a geometric progression is a(n) = a(1)*r^(n - 1), where r is the common ratio. In this problem, a(1) = -6250. To find r, we divide 1250 (the 2nd term) by -6250 (the 1st term), obtaining r = -0.2.
Then the formula for THIS geometric progression is
a(n) = -6250*(-0.2)^(n - 1).
Thus, the 7th term of THIS progression is
a(7) = -6250*(-0.2)^(7 - 1), or -6250*(-0.2)^6, or -0.4
Answer:
a₇ = - [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
The nth term of a geometric progression is
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = - 6250 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{1250}{-6250}[/tex] = - [tex]\frac{1}{5}[/tex] , then
a₇ = - 6250 × [tex](-\frac{1}{5}) ^{6}[/tex] = - 6250 × [tex]\frac{1}{15625}[/tex] = [tex]\frac{-6250}{15625}[/tex] = - [tex]\frac{2}{5}[/tex]

Income East and West of the Mississippi
For a random sample of households in the US, we record annual household income, whether the location is east or west of the Mississippi River, and number of children. We are interested in determining whether there is a difference in average household income between those east of the Mississippi and those west of the Mississippi.
Incorrect answer iconYour answer is incorrect.
(a) State the null and alternative hypotheses. Your answer should be an expression composed of symbols:
Let group 1 be the households east of the Mississippi River and let group 2 be the households west of the Mississippi River.
(b) What statistic(s) from the sample would we use to estimate the difference?
Let group 1 be the households east of the Mississippi River and let group 2 be the households west of the Mississippi River.
Answer:
H0: μ1 = μ2
H1: μ1 ≠ μ2 ;
xbar1 - xbar2
Step-by-step explanation:
The Null hypothesis should state that there is no difference in average household income between those located east and west of the Mississippi
H0: μ1 = μ2
H1: μ1 ≠ μ2
Statistic from the sample that would be used to estimate difference
Statistic refers to the numerical characteristic derived from the sample.
To estimate the difference in the average household income between those located east and west of the Mississippi, we take the sample mean of the two groups
Group 1, East of Mississippi = xbar 1
Group 2, West of Mississippi River = xbar 2
xbar1 - xbar2
estimate the product then find the product
Answer:
1 5/6 = 11/6
7 1/3 = 22/3
11/6 + 22/3 = 11/6 + 44/6 = 55/6 ≈ 9.16
1 5/6 = 11/6
11/6 - 1/10
55/30 - 3/30 = 52/30 ≈ 1.73
9.16 x 1.73 = 15.8468
So, 15.8468 is the result.
I hope this is helpful. :)

Question 3
The CEO of Hot Tires compares factory production for his two factories using the data in the table shown below.
Factory A Factory B
Production Production
Monday 102
112
Tuesday 106
119
Wednesday 114
105
Thursday 98
96
Friday
101
113
Which inference is valid?
A
Factory B produced more tires than factory A because factory B has a median of 112 and factory A has a median of 102
B
Factory B has less variability in production because the range for factory B is smaller than the range for factory A.
с
Factory A has less variability in production because the range for factory A is greater than the range for factory B.
D
Factory B produced more tires than factory A because factory Bhas a mean of 109 and factory A has a mean of 104.2.

Answer:
8
-4x+6(6-2x) = -7x - 36
-4x+36-12x = -7x-36
-16x+36 = -7x-36
-16x +7x = -36-36
-9x = -72
x = 72/9
x = 8

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.
Answer:
B
Step-by-step explanation:
RQ=TV
QS=VU
RS=TU
While proving that 2 triangles are congruent you have to consider the same side for both triangles.
The mistake you made was that you presumed that since both have equal sides they are equal,
In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.
B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched

Emma's Pizza can make 12 pizzas in 40 minutes. How many pizzas can they make in 5 hours?
Answer:
90
Step-by-step explanation:
Change 5 hours to minutes. (5x60, and 300 minutes)
Divide 300 by 40. (7.5)
Then, multiply 7.5 by 12 (90)
Answer:
90 pizzas
Step-by-step explanation:
We know 5 hours = [tex]5\times60 = 300[/tex] minutes
If you consider 20 minutes as a period, 5 hours .as well as 300 minutes. contains [tex]\frac{300}{20} = 15[/tex] periods.
Emma can make 12 pizzas in 40 minutes.
So she can make 6 pizzas in 20 minutes (in half time)
In 1 period she makes 6 pizzas.
In 15 periods she makes [tex]15\times6 = 90[/tex] pizzas (Answer.)

Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.

Solve for t. You must write your answer in fully simplified form.
−19=7t
Answer:
t=-19/7
Step-by-step explanation:
you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7
we know that anything divided by itself is 1 so we get -19/7=t
This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.
