Answers
Answer:
The increasing interval is [tex]S=(-2,\infty)[/tex]
Step-by-step explanation:
This absolute function has a vertex in x=-2. Now, from this point, the function has a positive slope (increasing), which means for values of x equals to -1,0,1,2,3,...,n.
Therefore the interval will

For your birthday, you want to take a group of friends to an indoor trampoline
center. There are two trampoline parks available on your date. You only have
$250 to spend on your party.
Pricing Information:
Sky High: $50 for a party set up fee and $5 per person after that. Write an inequality model for both trampoline parks.
Jump it Up: $70 for a party set up fee and $2 per person.
In jump it up you can bring 90 friends.
In Sky high, you can bring 40 friends.
Answers
Answer:
Skyhigh : 40 friends
Jump it up : 90 friends
Step-by-step explanation:
Given that :
Total amount available to spend = $250
JUMP IT UP:
Party set up fee = $70
Amount paid per person = $2
Number of friends = 90
SKY HIGH:
Party set up fee = $50
Amount paid per person = $5
Number of friends = 40
INEQUALITY :
Party setup fee + amount per person * Number of persons ≤ available amount to spend
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence,
Skyhigh = 90 friends
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up = 90
An experiment consists of tossing an unfair coin (48% chance of landing on heads) a specified number of times and recording the outcomes.
a. What is the probability that the first head will occur on the second trial?
b. Does the probability change if we toss the coin three times? What if we toss the coin four times?
Answers
Answer:
a. [tex]Probability = 0.2496[/tex]
b. No, it won't change
Step-by-step explanation:
Represent [tex]the\ head[/tex] with H and [tex]Tail\ with[/tex] T
Such that:
[tex]P(H) = 48\%[/tex]
Solving (a): First head in second trial
First, we determine P(T) i.e. the probability of obtaining a tail
[tex]P(H)+P(T) = 100\%[/tex]
[tex]P(T) = 100\% -P(H)[/tex]
Substitute 48% for P(H)
[tex]P(T) = 100\% -48\%[/tex]
[tex]P(T) = 52\%[/tex]
If the first head is obtained in the second trial, the probability is:
[tex]Probability = P(T\ and\ H)[/tex]
[tex]Probability = P(T)\ and\ P(H)[/tex]
[tex]Probability = P(T)\ *\ P(H)[/tex]
[tex]Probability = 48\%* 52\%[/tex]
[tex]Probability = 0.2496[/tex]
Solving (b): Will it change if tossed three or four times?
Irrespective of the number of times the coin is tossed, the probability of obtaining a head in the second toss will always be the same because the coin has to be tossed twice before the third and the fourth time.

You can solve the following proportion by cross multiplying. What will the equation be after you cross multiply?
3 x= 9 • 15
3 x = 15
3 • 15 = 9 X
15 = 9 X
Answers
=====================================
Explanation:
Anything in the form A/B = C/D will cross multiply to A*D = B*C
In this case, A = 3, B = 9, C = x and D = 15
So that's why 3/9 = x/15 cross multiplies to 3*15 = 9*x

We want to know the value when x = 21. Therefore, substitute x = 21 in the expression.
[tex]\frac{21-6}{3}[/tex]
Evaluate 21-6 = 15
[tex]\frac{15}{3}[/tex]
Therefore, the answer is 5.
A survey of 1000 Californians finds reports that 48% are excited by the opportunity to take a statistics class.
The margin of error in this report is 5%. Which answer choice best describes a reasonable range of values for the percent of
students who are excited to take a statistics class?
Answers
Answer:
(0.449, 0.511) is the range for the percent of students who are excited to take a statistics class
Step-by-step explanation:
First of all, let's check that the sample size is large enough to use normal approximation.
Conditions are;
np > 10
n(1-p) > 10
Now, we have;
n = 1000
p = 48% = 0.48
Thus;
np = 1000 × 0.48 = 480 > 10
Also;
n(1 - p) = 1000 × (1 - 0.48) = 520 > 10. This means the conditions for normal approximation have been fulfilled. Hence we can use the confidence interval formula to get the range of values which is;
CI = p ± z√(pq/n)
We are given a margin of error and thus the confidence interval is at 95%.
Critical value of z at 95% CI is 1.96
Thus;
CI = 0.48 ± 1.96√(0.48 × 0.52/1000)
CI = 0.48 ± 0.031
CI = (0.449, 0.511) is the range for the percent of students who are excited to take a statistics class
