Choose the most reasonable unit of measure.
3) Area of a baseball infield: 925
A) mm² B) km² C) m² D) cm²
4) Area of a lake: 4
A) mm² B) km² C) m² D) cm²
5) Area of a door: 20
A) yd² B) in.² C) ft² D) mi²
The most reasonable unit of measurement for 3) is option (C): \(m^2\), 4) is option (B): \(km^2\), 5) is \(in^2\).
3) The most reasonable unit for the measurement of the baseball field is \(m^2\) because the baseball field covers a large distance which is not accurately measured by small units \(cm^2\) or \(mm^2\) where it is not that big to be measured in large units like \(km^2\). So option C is the correct option.
4) The most reasonable unit for the measurement of a lake is \(km^2\) because lakes are generally very large water bodies that cover a large distance and are not accurately measured by small units like \(cm^2\) , \(mm^2\) , and \(m^2\). So option B is the correct option.
5) The most reasonable unit for the measurement of the area of a door is \(in^2\) because doors are relatively small compared to the other options and are often measured in square inches or square feet. So option B is the correct option.
Therefore the correct answers question-wise are:
3) \(m^2\)
4) \(km^2\)
5) \(in^2\)

Set up the appropriate equation to solve for the missing angle.
Answer:
Using the Pythagorean Theorem, we know x^2 + 46^2 is equal to 65^2. With that in mind, it is important to note:
65^2 = 4,225
46^2 = 2,116
To find the missing angle, we must subtract 2,116 from 4,225 and then identify the difference’s square root.
4,225 - 2,116 = 2,109
√2,109 ≈ 45
Hence, x ≈ 45.

back because they were too small. He caught 12
more in the afternoon. How many fish did dad
have then?
Is 29 the answer to this problem.
He caught 22 but put 5 back so had 22-5 = 17 fish
He then caught 12 more for a total of 17 + 12 = 29
Answer: 29 fish.
Answer:
The answer is 29 (so you were right!)
Step-by-step explanation:
He had 22 fish, and he threw 5 back
22 - 5 = 17
He caught 12 more in the afternoon
17 + 12 = 29
So, 29 is your answer.
Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following probability, given the number of trials and the probability of obtaining a success. Round your answer to four decimal places.
P(X<4), n=7, p=0.5
The probability P(X < 4) is approximately 0.2734 when X has a binomial distribution with n = 7 and p = 0.5.
When X has a binomial distribution with n = 7 and p = 0.5, we can use the cumulative distribution function (CDF) or the formula for the probability mass function (PMF) of the binomial distribution to determine the probability P(X 4) by adding the probabilities for X = 0, 1, 2, and 3.
Binomial CDF usage:
P(X 4) = P(X 3) = binom.cdf (3, n = 7, p = 0.5) 0.2734
Binomial PMF usage:
P(X 4) = P(X = 0), P(X = 1), P(X = 2), and P(X = 3) = binom.pmf(0, n=7, p=0.5), binom.pmf(1, n=7, p=0.5), binom.pmf(2, n=7, p=0.5), and binom.pmf(3, n=7, p=0.5), and binom.pmf(3, n=7, p=0.5) = 0.2734.
Since X has a binomial distribution with n = 7 and p = 0.5, the chance P(X 4) is roughly equal to 0.2734.

Ravi says,” if 10 years are added to my age, then my age becomes 25.”if Ravi’s present age is x years,
then find the linear equation satisfying the given condition.
Answer:
The linear equation satisfying the given condition is,
\(x=t+15\)
where x is Ravi's age and t is the number of years
(after 10 years (t=10) his age becomes 25)
Step-by-step explanation:
Let x be Ravi's age
Now, his current age is unknown, but if you add 10 to it, then it becomes 25, so
x + 10 =25
so, his current age is x = 25 =10
x = 15
Now, we find the linear equation satisfying the given condition,
Let t be the number of years that have passed since the present time
so, if 0 years have passed, his age will be 15 years
after 1 year, his age will be 16 years
after 10 years, his age will be 25 years and so on
so
\(x = t + 15\)
this satisfies the given condition, since if we add ten years i.e t = 10,
then we get 25
The equation is:
⇨ x + 10 = 25Work/explanation:
Here's the linear equation for Ravi's age.
Ravi's age is x.
If you add 10 to x you get x + 10.
That gives 25.
So the linear equation is x + 10 = 25.

What is a root ?
Mathematicians refer to a number as having a root if it can be multiplied by itself to give the original number. The square root of 49, for instance, is 7, as 77=49. 7 is referred to as the square root of 49 in this instance because it takes 49 to multiply 7 by itself twice. Considering that 333=27, the cube root of 27 is 3.
Quadratic equation's roots The roots of a quadratic equation are the values of the variables that fulfill the equation. In other words, if f() = 0, then x = is a root of the quadratic equation f(x). The x-coordinates of the sites where the curve y = f(x) intersects the x-axis are the real roots of an equation f(x) = 0.
3x^4 -10x^3 -9x^2 + 40x - 12

A production manager is interested in comparing the precision of two brands of stamping machines. From a random sample of 12 units of output from the Brand A machine, a standard deviation of 15.2 is reported for a quality characteristic. For the Brand B machine, in a sample of 20 units of output, there is a standard deviation of 10.1. Is there sufficient evidence at the 5% significance level to conclude that Brand B machines have a lower variance in quality
Answer:
There is insufficient statistical evidence at 5% significant level to conclude that Brand B machines have a lower variance in quality
Step-by-step explanation:
The given parameters are;
The number of units of the sample from Brand A, n₁ = 12 units
The standard deviation of the quality characteristic of Brand A, s₁ = 15.2
The number of units of the sample from Brand A, n₂ = 20 units
The standard deviation of the quality characteristic of Brand B, s₂ = 10.1
The null Hypothesis; H₀; s₁² = s₂²
The alternative Hypothesis; H₀; s₂²< s₁²
The difference of two variance formula;
The F test statistic is given as follows;
\(F = \dfrac{S_1^2}{S_2^2}\)
Where;
S₁² = The variance of sample (1) = 15.2² = 231.04
S₂² = The variance sample (2) = 10.1² = 102.01
df₁ = n₁ -1 = 12 - 1 = 11
df₂ = n₂ - 1 = 20 - 1 = 19
From the F table, we have the critical value from the F table = 2.66
\(F = \dfrac{S_1^2}{S_2^2} = \dfrac{231.04}{102.01} \approx 2.265\)
Therefore, given that F ≈ 2.265 is not larger than the critical F for α = 0.05, we do not reject the null hypothesis, and there is sufficient statistical evidence at 5% significance level to conclude that Brand B machines have the same variance in quality as Brand A machines

Which has a greater average rate of change over the interval where -1≤x≤3; the function
g(x)=x²+6x or the function f(x) = 2*. Provide justification for your answer.
Answer: Step-by-step explanation:
To find the average rate of change of a function over an interval, we can use the following formula:
average rate of change = (y2 - y1)/(x2 - x1)
Where x1 and x2 are the values of x at the beginning and end of the interval, and y1 and y2 are the corresponding values of the function at those points.
In this case, we are asked to compare the average rate of change of the functions g(x) and f(x) over the interval where -1≤x≤3.
For the function g(x) = x²+6x, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:
average rate of change = (g(3) - g(-1))/(3 - (-1))
= (9 + 18 - (1 - 6))/(4)
= 27/4
= 6.75
For the function f(x) = 2, we can plug in the given values for x1, x2, y1, and y2 to find the average rate of change:
average rate of change = (f(3) - f(-1))/(3 - (-1))
= (2 - 2)/(4)
= 0
Since the average rate of change of the function g(x) is greater than the average rate of change of the function f(x), the function g(x) has a greater average rate of change over the interval where -1≤x≤3.
I hope this helps clarify the comparison of the average rate of change for these two functions. Do you have any other questions?

\(\huge\boxed{\sf r = 5}\)
Step-by-step explanation:
Given that,
7(q + 5) = (q + r)7Distribute7q + 35 = 7q + 7r
Subtract 7q from both sides7q - 7q + 35 = 7q - 7q + 7r
35 = 7r
Divide both sides by 735/7 = r
5 = r
OR
r = 5\(\rule[225]{225}{2}\)
Answer:
r = 5
Step-by-step explanation:
Given statement,
→ 7(q + 5) is equivalent to (q + r)7.
Forming the equation,
→ 7(q + 5) = 7(q + r)
Now we have to,
→ Find the required value of r.
Then the value of r will be,
→ 7(q + 5) = 7(q + r)
Applying Distributive property:
→ 7(q) + 7(5) = 7(q) + 7(r)
→ 7q + 35 = 7q + 7r
Cancelling 7q from both sides:
→ 35 = 7r
→ 7r = 35
Dividing the RHS with number 7:
→ r = 35/7
→ [ r = 5 ]
Therefore, the value of r is 5.
Which property explains the step shown in solving the equation?5(x − 2) = 12x − 39 ⇒ 5x − 10 = 12x − 39A)Distributive PropertyB)Multiplicative IdentityC)Multiplication Property of EqualityD)Commutative Property of Multiplication
Given:
\(5(x-2)=12x-39\Rightarrow5x-10=12x-39\)Given equation is solved by distributive property.
Distributive property;
\(A(B-C)=AB-AC\)Therefore, Option A) Distributive property is the correct answer.
Hannah has a bag that contains pineapple chews, apple chews, and peach chews. She performs an experiment. Hannah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Hannah performs the experiment 20 times. The results are shown below:
A pineapple chew was selected 5 times.
A apple chew was selected 7 times.
A peach chew was selected 8 times.
Based on these results, express the probability that the next chew Hannah removes from the bag will be a flavor other than peach as a percent to the nearest whole number.
The probability that the next chew Hannah removes from the bag will be a flavor other than peach is 60%.
What is Probability?The probability of an event is a number used in science to describe how probable it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the probability, the more probable it is that the event will take place.
According to question:The total number of chews that Hannah removed from the bag is 20.
Out of these 20 chews, a peach chew was selected 8 times, so the number of non-peach chews is 20 - 8 = 12.
Therefore, the probability that the next chew Hannah removes from the bag will be a flavor other than peach is 12/20 = 0.6.
To express this probability as a percentage, we multiply it by 100 and round it to the nearest whole number:
0.6 * 100 = 60
So the probability that the next chew Hannah removes from the bag will be a flavor other than peach is 60%.
