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
Find the percent change from the first value to the second.
44;55
Step-by-step explanation:
Where: 44 is the old value and 55 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.
The solution is 20 %
The percentage change from the first value to the second value is 20 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Let the percentage change from first value to the second value be = A
Now , the first value = 44
The second value = 55
The percentage change is calculated from the formula ,
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Percentage Error = [ ( | 44 - 55 | ) / 55 ] x 100
On simplifying the equation , we get
Percentage Error = ( 11/55 ) x 100
Percentage Error = 100/5
Percentage Error = 20 %
Therefore , the value of A is 20 %
Hence , the percentage change from the original value is 20 %

Answer: Being dead is like being in a dream you can’t wake up from. Your soul is the only you have while everything else is gone. You feel numb
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]
Summary statistics are given for independent simple random samples from two populations. Use the nonpooled t-test to conduct the required hypothesis test. 1 = 75.1, s 1 = 4.5, n 1 = 11, 2 = 66.2, s 2 = 5.1, n 2 = 9 Perform a two-tailed hypothesis test using a significance level of α = 0.01.
Answer:
The decision rule is
Reject the null hypothesis
Step-by-step explanation:
From the question we are told that
The first sample mean is [tex]\= x_1 = 75.1[/tex]
The first sample standard deviation is [tex]s_1 = 4.5[/tex]
The first sample size [tex]n_1 = 11[/tex]
The second sample mean is [tex]\= x_2 = 66.2[/tex]
The second sample standard deviation is [tex]s_2 = 5.1[/tex]
The second sample size is [tex]n_2 = 9[/tex]
The significance level is [tex]\alpha = 0.01[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
Generally the pooled standard deviation is mathematically represented as
[tex]s = \sqrt{ \frac{(n_ 1 - 1) s_1^2 + (n_2 - 1) s_2^2}{n_1 + n_2 -2 } }[/tex]
=> [tex]s = \sqrt{ \frac{(11 - 1) 4.5^2 + (9 - 1) 5.1^2}{11 + 9 -2 } }[/tex]
=> [tex]s = 4.78[/tex]
Generally the degree of freedom for the is mathematically represented as
[tex]df = [ \frac{[\frac{s_1^2 }{n_1} + \frac{s_2^2}{ n_2} ]^2}{[\frac{[\frac{s_1^2}{n_1} ]^2}{n_1 - 1 } ] + [\frac{[\frac{s_2^2}{n_2} ]^2}{n_2 -1} ]} ][/tex]
=> [tex]df = [ \frac{[\frac{4.5^2 }{11} + \frac{5.1^2}{9} ]^2}{[\frac{[\frac{4.5^2}{11} ]^2}{ 11 - 1 } ] + [\frac{[\frac{5.1^2}{9} ]^2}{9 -1} ]} ][/tex]
=> [tex]df = 16 [/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x_1 - \= x_2}{ \sqrt{\frac{s_1^2 }{n_1} + \frac{s_2^2}{n_2} } }[/tex]
=> [tex]t = \frac{ 75.1 - 66.2 }{ \sqrt{\frac{ 4.5^2 }{ 11} + \frac{5.1^2}{ 9} } }[/tex]
=> [tex]t = 4.092[/tex]
Generally the student distribution table the probability of [tex]t = 4.092[/tex] to the right at a degree of freedom of [tex]df = 16 [/tex] is
[tex]P( T > 4.092 ) = 0.00042536[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(T > 4.092)[/tex]
=> [tex]p-value = 2 * 0.00042536[/tex]
=> [tex]p-value = 0.001[/tex]
From the value obtained we see that [tex]p-value < \alpha[/tex] hence we

In order for Mateen to walk a kilometer(1000m) in his rectangular backyard, he must walk the length 25 times or walk its perimeter 10 times. What is the area of Mateen's backyard in square meters
Answer:
400
Step-by-step explanation:
25 times the length is 1000 m.
Let length = L
25L = 1000
L = 40
10 times the perimeter is 1000 m.
Let the perimeter = P
10P = 1000
P = 100
perimeter = 2L + 2W
2(40) + 2W = 100
80 + 2W = 100
2W = 20
W = 10
The length is 40 m, and the width is 10 m.
A = LW
A = 40 m * 10 m
A = 400 m^2

One positive integer is 8 more than twice another. If their product is 384, find the numbers.
Answer: The numbers are 32 and 12
Step-by-step explanation:
Let say those two positve integers are x and y.
x has to be 8 more than twice y , and that could be represent by the equation
x = 2y + 8
Their product is 384 meaning that x times y has to equal to 384 , and that can also be represented by the equation xy = 384
x = 2y + 8
xy = 384
Now using both equations, substitute the value for x into the second equation and solve for y.
(2y + 8)(y ) = 384
2y^2 + 8y = 384 Subtract 348 from both sides
-384 -384
2y^2 + 8y - 384 = 0 Factor the left sides by the GCF
2(y^2 + 4y - 192) = 0
x = -b ± [tex]\sqrt{b^2 -4ac } /2[/tex]
The variables a= 1 , b=4 and c is -192
x = -4 ± [tex]\sqrt{784} /2[/tex]
x = -4 + 14 or x = -4 - 14
x = 12 or x = -16
Since we are dealing with length the value of y has to be 12.
Now that we know that y is 12 input 12 into one of the equations and solve for x.
x = 2(12) + 8
x = 24 + 8
x = 32

9514 1404 393
Answer:
slope: 3y-intercept: 10equation: y = 3x +10Step-by-step explanation:
The two-point form of the equation of a line can be used.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
For the two points, we choose to use ones near (0, 0):
(x1, y1) = (-8, -14) and (x2, y2) = (14, 52)
Then our equation is ...
y = (52 -(-14))/(14 -(-8))(x -(-8)) -14
y = 66/22(x +8) -14
y = 3x +24 -14
y = 3x +10 . . . . . the equation
The slope is the coefficient of x: 3.
The y-intercept is the added constant: 10, or coordinates (0, 10).

I NEED HELP!! please show all work
What is the exact solution to the equation?
4^(5x)=3^(x-2)
Take the logarithm of both sides. The base of the logarithm doesn't matter.
[tex]4^{5x} = 3^{x-2}[/tex]
[tex]\implies \log 4^{5x} = \log 3^{x-2}[/tex]
Drop the exponents:
[tex]\implies 5x \log 4 = (x-2) \log 3[/tex]
Expand the right side:
[tex]\implies 5x \log 4 = x \log 3 - 2 \log 3[/tex]
Move the terms containing x to the left side and factor out x :
[tex]\implies 5x \log 4 - x \log 3 = - 2 \log 3[/tex]
[tex]\implies x (5 \log 4 - \log 3) = - 2 \log 3[/tex]
Solve for x by dividing boths ides by 5 log(4) - log(3) :
[tex]\implies \boxed{x = -\dfrac{ 2 \log 3 }{ 5 \log 4 - \log 3 }}[/tex]
You can stop there, or continue simplifying the solution by using properties of logarithms:
[tex]\implies x = -\dfrac{ \log 3^2 }{ \log 4^5 - \log 3 }[/tex]
[tex]\implies x = -\dfrac{ \log 9 }{ \log 1024 - \log 3 }[/tex]
[tex]\implies \boxed{x = -\dfrac{ \log 9 }{ \log \frac{1024}3 }}[/tex]
You can condense the solution further using the change-of-base identity,
[tex]\implies \boxed{x = -\log_{\frac{1024}3}9}[/tex]

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.
