The owner of an Apple orchard wants to buy more trees the table below shows the cost for buying different numbers of trees. pls help me
Answer:
We conclude that the cost of 10 trees will be: $350
Step-by-step explanation:
From the table, it is clear that:
The cost of 6 trees = $210
So the cost of 1 tree = 210/6 = $35
The cost of 13 trees = $455
So the cost of 1 tree = 455/13 = $35
The cost of 18 trees = $630
So the cost of 1 tree = 630/18 = $35
Thus, the table indicates that the cost of 1 tree = $35
In other words,
unit rate = $35 per treeTherefore, the cost of 10 trees will be: 35 × 10 = $350
Thus, we conclude that the cost of 10 trees will be: $350
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
=====================================
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

on what interval is the function h(f)=|x+2|-2 increasing ?
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
[tex]S=(-2,\infty)[/tex]

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?
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

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?
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.

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.
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

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 1 and the Trailing Constant is -9.
The factor(s) are:

In 1965, about 44% of the U.S. adult population had never smoked cigarettes. A national health survey of 1472 U.S. adults (presumably selected randomly) during 2010 revealed that 677 had never smoked cigarettes.Suppose you wished to test whether there has been a change since 1965 in the proportion of U.S. adults that have never smoked cigarettes. You suspect that the proportion has grown since 1965. Which of the following are the appropriate hypotheses?A. H0: p = 0.44, Ha: p > 0.44B. H0: p = 0.51, Ha: p In 1965, about 44% of the U.S. adult population ha 0.51C. H0: p = 0.44, Ha: p In 1965, about 44% of the U.S. adult population ha 0.44D. H0: In 1965, about 44% of the U.S. adult population ha = 0.44, Ha: In 1965, about 44% of the U.S. adult population haIn 1965, about 44% of the U.S. adult population ha 0.44
Answer:
H0: p = 0.44, Ha: p ≠ 0.44
Step-by-step explanation:
The following information is mentioned
44% of the US adult population would never smoked cigarettes so that means the proportion would be
= 44 ÷ 100
= 0.44
Now we have to check the test whether this change represent increase or decrease
So the hypothesis is
[tex]H_o: P=0.44[/tex]
[tex]H_1: P \neq 0.44[/tex]
The two tailed means
[tex]P < 0.44 \, \, or \, \, P> 0.44 )[/tex]
