(7) The sum of five consecutive even integers is at least 400 . What is the minimum value of the first even integer? Choose from the following solutions:
A 80
B 70
C 76
D 82
Answer:
C 76
Step-by-step explanation:
let x = 1st number
let x+ 2 = 2nd number
let x + 4 = 3rd number
let x + 6 = 4th number
Let x + 8 = 5th number
x + x + 2 + x+ 4 + x + 6 + x + 8 = 400 Combine like terms
5x + 20 = 400 Subtract 20 from each side
5x = 380 Divide both sides by 5
x = 76
Check:
76 + 78 + 80 + 82 + 84 = 400

Step-by-step explanation:
We know this triangle is a right angled triangle due to the symbol shown in the corner, this means that pythagoras theorem can be used:
\(a^2 + b^2 = c^2\)
However, one of the sides is unknown so we need to change the equation subject to a or b:
\(a^2 = c^2 - b^2\)
Now we can simply plug the values in:
\(a^2 = 15^2 - 5^2\)
\(a^2 = 225 - 25\)
\(a^2 = 200\\\)
Now square root both sides to find a:
\(\sqrt{a^2} = \sqrt{200}\)
\(a = \sqrt{200}\)
a = 14.14
x = 14.14 mi

State the final conclusion in simple nontechnical terms.
Original claim: The proportion of male golfers is less than 0.6.
Initial conclusion: Fail to reject the null hypothesis.
Which of the following is the correct conclusion?
A. There is suffficient evidence to support the claim that the proportion of male golfers is less than 0.6.
B. There is not sufficient evidence to support the claim that the proportion of male golfers is less than 0.6.
Answer:
B. There is not sufficient evidence to support the claim that the proportion of male golfers is less than 0.6.
Step-by-step explanation:
The proportion of male golfers is less than 0.6.
At the null hypothesis, we test if the proportion is of at least 0.6, that is:
\(H_0: p \geq 0.6\)
At the alternative hypothesis, we test if the proportion is of less than 0.6, that is:
\(H_1: p < 0.6\)
Fail to reject the null hypothesis.
This means that there is not sufficient evidence to conclude that the proportion is less than 0.6, and thus the correct answer is given by option B.
x = 49 is a solution for the equation x - 23=26 true or false
To check if x = 49 is a solution of an equation, you have to replace the x-value into the equation as follows:
x - 23 = 26
49 - 23 = 26
26 = 26
Given that there is the same number on both sides of the equal sign, then x = 49 is a solution to the equation

There is a 30% probability of choosing an odd number and an additional odd number.
We must take into account the total number of cards and the number of favourable outcomes in order to calculate the probability of selecting an odd number and then choose an odd number without replacement.
The cards are: 2 3 4 56.
There are five cards in all. There are two even numbers (2, 4) and three odd numbers (3-5).
Out of a total of 5 possible outcomes, 3 favourable outcomes (3, 5, 6) can be used to determine the likelihood of selecting an odd number first.
Picking an odd number first has a 3/5 chance of happening.
There are now 4 cards left, 2 of which have odd numbers (3, 5) and 2 of which have even numbers (2, 4), after selecting an odd number.
Out of a total of 4 possible outcomes, we have 2 favourable outcomes (3, 5) that we may use to determine the chance of selecting an odd number second.
Choosing an odd number second has a 2/4 chance of happening.
Since the two events are separate, we may add their probabilities to determine the likelihood that both will occur:
P(Odd and Odd) = P(Odd first) * P(Odd second)
= (3/5) * (2/4)
= 6/20
= 0.3
We multiply the chance by 100 to express it as a percentage:
P(Odd and Odd) = 0.3 * 100
= 30%

Answer:
Exponential Function
General form of an exponential function with base \(e\):
\(f(x)=Ae^{kx}\)
where:
A is the y-intercepte (Euler's number) is the basek is some constantQuestion 30The curve crosses the y-axis at y = 40. Therefore, A = 40.
Substitute the found value of A into the formula along with (1, 56) and solve for \(k\):
\(\begin{aligned}f(x) & =Ae^{kx}\\\implies 56 & =(40)e^{k}\\e^k & =\dfrac{56}{40}\\k & =\ln (1.4)\end{aligned}\)
\(\textsf{Equation}: \quad f(x)=40e^{x\ln 1.4}\)
To find the population in 10 years, substitute \(x = 10\) into the found equation:
\(\begin{aligned}\implies f(10)&=40e^{10\ln 1.4}\\ & =1157.01862\\ & =1157\end{aligned}\)
Question 31The curve crosses the y-axis at y = 10. Therefore, A = 10.
Substitute the found value of A into the formula along with (1, 18) and solve for \(k\):
\(\begin{aligned}f(x) & =Ae^{kx}\\\implies 18 & =(10)e^{k}\\e^k & =\dfrac{18}{10}\\k & =\ln (1.8)\end{aligned}\)
\(\textsf{Equation}: \quad f(x)=10e^{x\ln 1.8}\)
To find the population in 8 years, substitute \(x = 8\) into the found equation:
\(\begin{aligned}\implies f(8)&=10e^{8\ln 1.8}\\ & =1101.996058\\ & =1102\end{aligned}\)

Find the minimum and maximum values of the objective function, and the points at which these values occur subject to the given constraints. Round your answers to the
nearest hundredth.
The minimum value of the objective function is 47, which occurs at the point (3,2), and the maximum value is 117, which occurs at the point (0,9).
To solve this linear programming problem, we need to first graph the feasible region defined by the given constraints:
The first constraint, x ≥ 0, represents the non-negative values of x along the x-axis.
The second constraint, 4x + 8y ≥ 32, can be rewritten as y ≥ -(1/2)x + 4, which is a line with a y-intercept of 4 and a slope of -(1/2). The feasible region is above this line.
The third constraint, 10x - y ≤ 30, can be rewritten as y ≥ 10x - 30, which is a line with a y-intercept of -30 and a slope of 10. The feasible region is above this line as well.
The fourth constraint, x + 6y ≤ 54, can be rewritten as y ≤ -(1/6)x + 9, which is a line with a y-intercept of 9 and a slope of -(1/6). The feasible region is below this line.
The feasible region is therefore the polygon bounded by the lines y = -(1/2)x + 4, y = 10x - 30, y = -(1/6)x + 9, and x = 0. To find the minimum and maximum values of the objective function f(x,y) = 11x + 13y, we need to evaluate this function at each corner of the feasible region and compare the results.
The corners of the feasible region are (0,4), (3,2), (5,4), and (0,9). Evaluating the objective function at these corners, we get:
f(0,4) = 52
f(3,2) = 47
f(5,4) = 89
f(0,9) = 117
Therefore, the minimum value of the objective function is 47, which occurs at the point (3,2), and the maximum value is 117, which occurs at the point (0,9).

Fill in the blank using the scaling factor that makes the number sentence true. 5.3 × > 5.3 0.886 or 1.00 or 1.003
The given options, the only value greater than 1 is 1.003. Therefore 0.886, which is less than 1 and makes the inequality true.
The given number sentence is 5.3 × > 5.3, where we need to find the scaling factor that makes the inequality true. To do this, we can divide both sides of the inequality by 5.3. This gives us:
5.3 × x > 5.3 ÷ 5.3 × k
We need to find the value of k that makes the inequality true. Simplifying the right-hand side of the equation, we get:
5.3 ÷ 5.3 × k = k × 1 = k
Substituting this into our equation, we get:
5.3 × x > k
We know that 5.3 × 1 = 5.3, which means that k must be greater than 1 to satisfy the inequality. Among the given options, the only value greater than 1 is 1.003. However, this value would make the inequality too large, so it is not the correct answer.
The correct answer is therefore 0.886, which is less than 1 and makes the inequality true.

Alice and Bob each have a certain amount of money. If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. If, on the other hand, she gives n dollars to Bob, then she will have 2 times as much money as Bob. If neither gives the other any money, what is the ratio of the amount of money Alice has to the amount Bob has?
The ratio of the amount of money Alice has to the amount Bob has is approximately 3.36 : 1.
How to find the ratio of money ?According to the problem, two equations can be set up:
If Alice receives n dollars from Bob, then she will have 7 times as much money as Bob. This gives us the equation:
A + n = 7(B - n)
If Alice gives n dollars to Bob, then she will have 2 times as much money as Bob. This gives us the second equation:
A - n = 2(B + n)
We can rearrange these equations to make them easier to solve:
8n = 7B - A
3n = A - 2B
Setting these equal to each other, since they are both equal to 24n, gives:
21B - 3A = 8A - 16B
37B = 11A
A / B = 37 / 11
