Of the 4 students who owned a TI calculator, 2 had graphing calculators. Estimate the proportion of students who do not own a TI graphing calculator. 2 Incorrect: Your answer is incorrect.
Based on the given information, we can estimate that out of the total population of students, 2 out of 4 students (or 50%) own graphing TI calculators so it can be estimated that the proportion of students who do not own a TI graphing calculator is 50%.
To estimate the proportion of students who do not own a TI graphing calculator, we can use the information provided that out of the 4 students who owned a TI calculator, 2 had graphing calculators. Since we know that all graphing calculators are TI calculators, we can assume that the 2 students with graphing calculators are included in the total count of students who own TI calculators. Therefore, the remaining 2 students who own TI calculators must have non-graphing calculators.
Based on this information, we can estimate that out of the total population of students, 2 out of 4 students (or 50%) own non-graphing TI calculators. Therefore, we can estimate that the proportion of students who do not own a TI graphing calculator is 50%.
It's important to note that this is an estimation based on the limited information provided. To obtain a more accurate estimate, a larger sample size or more comprehensive data would be needed. Additionally, this estimation assumes that the sample of 4 students is representative of the entire student population in terms of calculator ownership. If there are any biases or limitations in the sampling method or if the sample is not representative, the estimate may not accurately reflect the true proportion of students who do not own a TI graphing calculator.

an aircraft had a 100 hour inspection when the tachometer read 1259.6. when is the next 100 hour inspection due
Answer:
1359.6
Step-by-step explanation:
To determine when the next 100-hour inspection is due, we need to add 100 hours to the current tachometer reading of 1259.6.
1259.6 + 100 = 1359.6
Therefore, the next 100-hour inspection is due when the tachometer reading reaches 1359.6.

Answer:
\( \frac{51}{6} \)
or
\(8 \times \frac{1}{2} \)
(depending on what you need)
or you can write it just like 8.5
Step-by-step explanation:
So I think it says,
\(8 \times \frac{5}{12} = \)
and then,
\( +31 \times \frac{1}{6} = \)
So- I'm guessing the question overall would look like the following:
\((8 \times \frac{5}{12}) + 31 \times \frac{1}{6} = \)
The parenthesis is simple enough. 5×8 = 40
\( \frac{40}{12} + 31 \times \frac{1}{6} = \)
And the second half is even simpler since 31×1 = 31:
\( \frac{40}{12} + \frac{31}{6} = \)
Okay and now we can shorten the left fraction, which means that we cut it in half.
\( \frac{20}{6} + \frac{31}{6} = \)
Almost done, now we just add them together.
\( = \frac{51}{6} \)
There we have it. And if needed you can also write it like:
\(8 \times \frac{3}{6} \)

The population of a country is growing exponentially. The population in millions was 90 in 1970 and 120 in 1980. (a) What is the population t years after 1970? 90e^(0.02876820t) (b) How long does it take the population to double? 24.094 (c) When will the population be 400 million?
The population of a country is growing exponentially means that the population increases by a certain percentage every year. (a) The population t years after 1970 is 90e^(0.02876820t). (b) It will take 24.094 years for the population to double. (c) The population will be 400 million 51.348 years after 1970, which is in the year 2021.348.
The formula for exponential growth is P(t) = P0e^(rt), where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and t is the time in years.
(a) P0 is 90 million. The growth rate, r, is,
120 = 90e^(r*10)
Dividing both sides by 90 gives:
1.333 = e^(r*10)
Taking the natural logarithm of both sides gives:
ln(1.333) = r*10
So,
r = 0.02876820
Plugging this value back into the formula gives:
P(t) = 90e^(0.02876820t)
This is the population t years after 1970.
(b) solve for t when P(t) = 2P0.
2P0 = P0e^(rt)
Dividing both sides by P0 gives:
2 = e^(rt)
Taking the natural logarithm of both sides gives:
ln(2) = rt
So,
t = ln(2)/r
Plugging in the value of r gives:
t = ln(2)/0.02876820
t = 24.094
So it takes 24.094 years for the population to double.
(c) solve for t when P(t) = 400.
400 = 90e^(0.02876820t)
Dividing both sides by 90 gives:
4.444 = e^(0.02876820t)
Taking the natural logarithm of both sides gives:
ln(4.444) = 0.02876820t
So,
t = ln(4.444)/0.02876820
t = 51.348
So the population will be 400 million 51.348 years after 1970, which is in the year 2021.348.

Sophia throws a dart at this square-shaped target:
part a: is the probability of hitting the black circle inside the target closer to 0 or 1? explain your answer.
part b: is the probability of hitting the white portion of the target closer to 0 or 1? explain your answer.
Part a: The probability of hitting the black circle inside the target is closer to 0.
The black circle appears to be a relatively small area within the larger square-shaped target. Assuming Sophia's dart can hit any point within the target with equal probability, the probability of hitting the small black circle is lower compared to hitting any other point within the larger target area. Therefore, the probability of hitting the black circle is closer to 0 than to 1.
Part b: The probability of hitting the white portion of the target is closer to 1.
The white portion of the target comprises the majority of the square-shaped target area, excluding the black circle. Assuming Sophia's dart can hit any point within the target with equal probability, the probability of hitting the white portion is higher compared to hitting the small black circle. Therefore, the probability of hitting the white portion is closer to 1 than to 0.

evaluate the integral ∫ ( 2 x 3 ) ( x 2 3 x 6 ) 5 d x by making the substitution u = x 2 3 x 6 .
Substituting u = x^(2/3x^6) in the integral ∫ (2x^3)(x^2/3x^6)^5 dx and arriving at the solution 3∫(x^3)(u^5) du.
To evaluate the integral ∫ (2x^3)(x^2/3x^6)^5 dx, we can simplify the expression by making the substitution u = x^(2/3x^6). This substitution allows us to transform the integral into a simpler form, making it easier to evaluate.
Let's make the substitution u = x^(2/3x^6). Taking the derivative of both sides with respect to x gives us du = (2/3x^6)(x^(-1/3)) dx. Simplifying this equation, we have du = (2/3)dx.
Now, we can rewrite the original integral in terms of u as follows:
∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx.
Using our substitution, we can also rewrite x^3dx as (3/2)du. Substituting these into the integral, we have:
∫ (2x^3)(x^(2/3x^6))^5 dx = ∫ (2x^3)(u^5) dx = 2∫(x^3)(u^5)dx = 2∫(x^3)(u^5)(3/2)du.
Simplifying further, we have:
∫ (2x^3)(x^(2/3x^6))^5 dx = 2(3/2) ∫ (x^3)(u^5) du = 3∫(x^3)(u^5) du.
Now, we can evaluate this integral with respect to u, which gives us a simpler expression to work with. Once we find the antiderivative of (x^3)(u^5) with respect to u, we can substitute u back in terms of x to obtain the final result.

By finding 59% of 50.7 million we know that approximately 29.9 million travelers are originating from the Southeast.
To find the number of travelers originating from the southeast, we need to calculate 59% of the total number of travelers.
The total number of travelers estimated is 50.7 million.
To find 59% of 50.7 million, we can multiply 50.7 million by 0.59:
\(50.7 million * 0.59 = 29.913 million\)

To the nearest tenth of a million, approximately 20.3 million travelers are originating from the southeast region.
The ratio of the numbers of travelers from the southeast, midwest, and northeast regions is given as 6:5:4, respectively. To find the number of travelers originating from the southeast region, we need to determine the value of one part of the ratio.
Let's assume the common ratio value is "x". According to the given ratio, the number of travelers from the southeast region can be represented as 6x.
We know that the total number of travelers is estimated to be 50.7 million. Therefore, we can set up the following equation:
6x + 5x + 4x = 50.7
Combining like terms, we get:
15x = 50.7
To solve for x, we divide both sides of the equation by 15:
x = 50.7 / 15
Evaluating this expression, we find:
x ≈ 3.38
Now, to find the number of travelers originating from the southeast region, we multiply the value of x by the corresponding ratio:

For a particular circle, a central angle of 75 degrees will intercept an arc of length 10pi feet. What is the radius of this circle?
The radius of the circle is 48 feet.
Circle:
The round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center)
The arc length of a circle is given by the formula arc length = (angle/360) * 2 * pi * radius.
In this case, the angle is 75 degrees, and the arc length is 10* pi feet.
So, we can set up the equation: (75/360) * 2 * pi * r = 10 * pi
Solving this equation for the radius, we get: r = (10pi) / ( (75/360) * 2 * pi) = (10360) / 75 = 48 feet. So, the radius of the circle is 48 feet.

tori went to the eye doctor. he dilated her pupils to twice their normal size during the exam. if her pupils were mm originally, what size were they after being dilated? math models unit 2
Her pupils were 2 * mm after being dilated.
Step 1: Identify the original size of Tori's pupils, which is "mm".
Step 2: Since her pupils were dilated to twice their normal size, multiply the original size by 2.
Calculation: mm * 2
If Tori's pupils were originally x mm in size, and they were dilated to twice their normal size, we can set up the following equation:
2x = size after dilation
To find the size of her pupils after dilation, we need to solve for "size after dilation" in the equation above.
Dividing both sides of the equation by 2, we get:
x = (size after dilation) / 2
Therefore, the size of Tori's pupils after being dilated is x/2 mm.
So, the size of Tori's pupils after being dilated would be 2 * mm, or simply 2mm.
