Write your answer as an ordered pair with no spaces (x,y)

Answers

Answer:

(1/2,1/4) because m= 1/5 and m= 1/2 and te equation is y=1/4x - 5/2 and y= 1/2x - 1

2x-4y=4---(1)x-4y=10---(2)

Substracting both

[tex]\\ \sf\Rrightarrow x=4-10=-6[/tex]

Putting in eq(2)

[tex]\\ \sf\Rrightarrow -6-4y=10[/tex]

[tex]\\ \sf\Rrightarrow -4y=16[/tex]

[tex]\\ \sf\Rrightarrow y=-4[/tex]

Hence our solution is

(x,y)=(-6,-4)

Given The recourse recursive formula, find the first four terms:

Answers

Answer:

Step-by-step explanation:

we are given that

[tex] \displaystyle a_{n} = - 3 \: \cdot a_{n - 1} \\ a_{1} = 45[/tex]

we are already given our first term i.e 45

for second term

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{2- 1} [/tex]

simplify substraction:

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{1} [/tex]

since we have [tex]a_1=45[/tex]

substitute:

[tex] \displaystyle a_{2} = - 3 \: \cdot 45[/tex]

simplify multiplication:

[tex] \displaystyle a_{2} = - 135[/tex]

for third term

[tex] \displaystyle a_{3} = - 3 \: \cdot a_{3- 1} [/tex]

simplify Substraction:

[tex] \displaystyle a_{3} = - 3 \: \cdot a_{2} [/tex]

as [tex]a_2=-135[/tex]

substitute:

[tex] \displaystyle a_{3} = - 3 \: \cdot - 135[/tex]

simplify multiplication:

[tex] \displaystyle a_{3} = 405[/tex]

for forth term

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{4- 1} [/tex]

simplify Substraction:

[tex] \displaystyle a_{2} = - 3 \: \cdot a_{3} [/tex]

substitute:

[tex] \displaystyle a_{2} = - 3 \: \cdot 405[/tex]

simplify multiplication:

[tex] \displaystyle a_{2} = - 1215[/tex]

hence,

the first four terms are 45,-135,405,-1215

Step-by-step explanation:

hence,

the first four terms are 45,-135,405,-1215

2. Write the sum using summation notation, assuming the suggested pattern continues.
-9 - 4 + 1 + 6 + ... + 66

Answers

Answer:

Step-by-step explanation:

a=-9

d=-4-(-9)=-4+9=5

l=66

l=a+(n-1)d

66=-9+(n-1)5

66+9=(n-1)5

n-1=75/5=15

n=15+1=16

Sn=n/2 {-18+(n-1)5}

=n/2{5n-23}

so reqd. sum is ∑[n/2{5n-23}] where n from 1→16

Two students in the same Spanish class, Perry and Dakota, plan to get together after school
to make vocabulary flashcards. Perry started on the project yesterday and has already made
5 flashcards. Dakota hasn't started yet. Since Perry makes 4 flashcards per minute and
Dakota makes 5 flashcards per minute, Dakota will soon have the same number of
flashcards. How many flashcards will each student have at that point?
Write a system of equations, graph them, and type the solution.

Answers

Answer:

Dakota=20 perry=25 together= 45

Step-by-step explanation:

First step, remember to keep 5

second step, if they are find keep multiplying until they both meet the same number which is 20, but they both have 20. But Perry will have 25 since he started a day before

The Skate Center charges a $50 flat fee kick-back party rental and $5.50 for each person who attends. Your parents gave you no more than $300 to spend on the party. How many people can you invite to the party without going over budget? I NEED THE ANSWER QUICK!

Answers

Answer: 45 people

Step-by-step explanation:

Data: $50 to rent the Skate Center

$5.50 for each person who attends

Limit of spending: $300

How many people can attend=x

Step one, Make the equation

$5.50x+$50=$300

Reason: Since we know that amount of people(x) multiplied by $5.50 added to $50 will get us $300, we can make an equation from that. The equation will make the problem simpler to solve.

Step two, Start isolating x by subtracting $50 on both sides

$5.50x+$50-50=$300-50=$5.50x=$250

Reason: Since we have to find x, we have to isolate it. The first step in doing that is subtracting $50 by 50 to get rid of it. However, since what you do to one side, you do to the other, you have to subtract $300 by 50 to get $250.

Step three, Divide by 5.50 on both sides

$5.50x/5.50=$250/5.50=x=45.454545454-

Reason: Since we have to isolate x and 5..50 is being multiplied by x, you have to divide it by 5.50 to get rid of 5.50. What you do to one side, you do to the other so you divide 250/5.50 to get 45.4545454545-.

Since this is a irl problem, you have to round it to 45 people

Answer: 45 people

For each of the following scenarios, simply state WHICH technique would be the most appropriate method to analyze the results.

a. Sam wants to know if students spend more time studying for midterms or for finals. She asks 30 people how many hours they studied for each exam, and records their responses. She expects that students spend more time studying for finals.
b. Michael thinks that people who travel more report higher quality of life. To test this, Michael studies a group of 20 people across many years. He gets them to rate their quality of life (on a scale from 1-10) before they’ve travelled at all, again after they’ve taken their first trip abroad and again after their third trip abroad. Michael compares the data at the three time points to see if his hypothesis is correct.
c. Meredith wants to know if a new medication affects sleep. So, she takes a sample of 81 people and has them all take the medication for a week. During that time, those 81 people record the number of hours they slept. If you are given M = 42, µ = 45 and σ = 8, how can you determine whether the medication affects the number of hours people sleep.
d. In the previous question, if you were given the standard deviation for the group of 81 people only, instead of σ, what would you do to answer the same question?

Answers

Answer:

Below is the solution to the given points:

Step-by-step explanation:

For point a:

There have 30 overviews paired here and we'd like to analyze the mean studying time in the middle and final periods. It will employ a paired t-test. The difference (d) = mid - final

Hypotheses:

[tex]H_o: \mu_d \geq 0\\\\H_a: \mu_d < 0[/tex]

For point b:

More than three variables should be examined here because ANOVA is employed in one method.

For point c:

This one Z test is used since we have the standard difference in population.

Hypotheses:

[tex]H_o:\mu = 45\\\\ H_a:\mu\neq 45[/tex]

For point d:

Since not knowing the sample standard deviation, we will use an individual sample t-test.
