If the arc of a circle has length 10π and the circumference of the circle is 30π, what is the measure of the central angle that intercepts the arc?
We have been given that the arc of a circle has length 10π and the circumference of the circle is 30π. We are asked to find the measure of the central angle that intercepts the arc.
We will use arc length and circumference of circle formula to solve our given problem.
[tex]l=r\theta[/tex], where,
l = Arc length,
r = radius,
[tex]\theta[/tex] = Central angle that intercepts to arc.
[tex]C=2\pi r[/tex], where C represents circumference of circle.
We can solve for radius using circumference formula as:
[tex]30\pi=2\pi r[/tex]
[tex]\frac{30\pi}{2\pi}=\frac{2\pi r}{2\pi}[/tex]
[tex]15=r[/tex]
Upon substituting arc length and radius in arc length formula, we will get:
[tex]10\pi =15\theta[/tex]
[tex]\frac{10\pi}{15} =\frac{15\theta}{15}[/tex]
[tex]\frac{2\pi}{3} =\theta[/tex]
Therefore, the measure of central angle that intercepts the arc would be [tex]\frac{2\pi}{3}[/tex].

The table shows the results of an experiment in which subjects taking either a drug or a placebo either reported fatigue or did not report fatigue.
Which calculation shows that selecting a subject who took the drug and selecting a subject who reported fatigue are dependent events?
Choose all answers that are correct.
— P(drug) = 0.6
P(drug | fatigue) ≈ 0.727
0.6 ≠ 0.727
— P(fatigue) = 0.44
P(fatigue | drug) ≈ 0.533
0.44 ≠ 0.533
— P(drug) = 0.6
P(fatigue) ≈ 0.44
0.6 ≠ 0.44
—P(drug and fatigue) = 0.32
P(drug) • P(fatigue) = 0.264
0.33 ≠ 0.264
Answer:
Therefore, the correct options are;
-P(fatigue) = 0.44
[tex]P(fatigue \left | \right drug)[/tex] = 0.533
--P(drug and fatigue) = 0.32
P(drug)·P(fatigue) = 0.264
Step-by-step explanation:
Here we have that for dependent events,
[tex]P(A \, and \, B)= P(A)\times P(B\left | \right A )[/tex]
From the options, we have;
[tex]P(fatigue \left | \right drug)[/tex] = 0.533
P(drug) = 0.6
P(drug and fatigue) = 0.32
Therefore
P(drug and fatigue) = P(drug)×[tex]P(fatigue \left | \right drug)[/tex]
= 0.6 × 0.533 = 0.3198 ≈ 0.32 = P(drug and fatigue)
Therefore, the correct options are;
-P(fatigue) = 0.44
[tex]P(fatigue \left | \right drug)[/tex] = 0.533
--P(drug and fatigue) = 0.32
P(drug)·P(fatigue) = 0.264
Since P(fatigue) = 0.44 ∴ P(drug) = 0.264/0.44 = 0.6.

A 2015 Gallup poll of 1,627 adults found that only 22% felt fully engaged with their mortgage provider.
What is the sample size?
The margin of error for this data set is 2.5%. What is the 95% confidence interval using only 1 decimal?
Final answer:
The sample size for the Gallup poll is 1,627 adults. For the 95% confidence interval with a 2.5% margin of error and an engagement rate of 22%, the interval is (19.5%, 24.5%).
Explanation:
The sample size mentioned in the Gallup poll is 1,627 adults. To calculate the 95% confidence interval for the estimated proportion of adults who felt fully engaged with their mortgage provider, we use the provided percentage (22%) and the margin of error (2.5%).
The confidence interval formula is:
Confidence Interval = Estimate ± Margin of Error
In this case, the point estimate is 22% (or 0.22 as a decimal). The margin of error (MOE) is 2.5% (or 0.025 as a decimal).
To find the confidence interval, we subtract and add the margin of error from the point estimate:
Lower limit = 0.22 - 0.025 = 0.195
Upper limit = 0.22 + 0.025 = 0.245
Therefore, the 95% confidence interval in decimal form is (0.195, 0.245). Converting to percentages and rounding to one decimal place, we obtain:
95% Confidence Interval: (19.5%, 24.5%)
The sample size for the Gallup poll is 1,627 adults. 95% confident that the true proportion of all adults who feel fully engaged with their mortgage provider is between 19.5% and 24.5%.
To find the 95% confidence interval, we use the formula for a confidence interval for a proportion, which is given by:
[tex]\[ \text{Confidence Interval} = \hat{p} \pm Z \times \sqrt{\frac{\hat{p}(1 - \hat{p})}{n}} \][/tex]
where:
- [tex]\( \hat{p} \)[/tex] is the sample proportion (0.22 in this case),
- Z is the Z-score corresponding to the desired confidence level (1.96 for 95% confidence),
- n is the sample size (1,627 in this case).
The margin of error (ME) is calculated by:
[tex]\[ ME = Z \times \sqrt{\frac{\hat{p}(1 - \hat{p})}{n}} \][/tex]
Given that the margin of error is 2.5%, we can solve for the standard error (SE) and then use it to find the confidence interval.
[tex]\[ ME = Z \times SE \] \[ 0.025 = 1.96 \times SE \] \[ SE = \frac{0.025}{1.96} \] \[ SE \approx 0.01276 \][/tex]
Now we can find the confidence interval:
[tex]\[ \text{Lower bound} = \hat{p} - ME = 0.22 - 0.025 = 0.195 \] \[ \text{Upper bound} = \hat{p} + ME = 0.22 + 0.025 = 0.245 \][/tex]
Therefore, the 95% confidence interval for the proportion of adults who felt fully engaged with their mortgage provider is approximately (19.5%, 24.5%).

What is mean by equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides.
As, the solution given:
put x=3
y-1 = 0
y=1
Similarly, x= 6
y-1= 5/3 (3)
y-1 = 5
y=6
Hence, the lines represent y-1 = 5/3 ( x- 3)

Answer:
f(x) = [tex]3^x[/tex]
Step-by-step explanation:
This doesn't really look like a linear model, so it might be exponential.
Let's write the equation: y = a[tex]b^x[/tex]. Plug in a few values for y and x to find a and b:
9 = a[tex]b^2[/tex] ⇒ a = 9/b²
27 = a[tex]b^3[/tex] ⇒ a = 27/b³
Set these equal:
9/b² = 27/b³
9b = 27
b = 3
Plug this in to find a:
a = 9/b² = 9/9 = 1
The equation is:
f(x) = [tex]3^x[/tex]
Answer:
Y = 3^X
Step-by-step explanation:
this is an exponential function
Y = a(b^X)
9 = ab²
27 = ab³
b = 3
9 = a(3)²
a = 1
Find the value of X in this equilateral triangle.
Answer:
x=4
Step-by-step explanation:
Since this is an equilateral triangle, all the sides are equal
6x = 4x+8 = 3x +12
Using the last 2 parts
4x+8 = 3x +12
Subtract 3x from each side
4x-3x +8 =3x+12-12
x+8 = 12
Subtract 8 from each side
x+8-8=12-8
x = 4
There are 213 guests waiting in line for a water-rafting ride at Splash Pad Water
Park. A maximum of 7 people can ride a raft at one time. What is the smallest
number of rafts the water park needs for this number of guests? HINT: Is there a
remainder in this problem? If so, solve the division problem and then go back and
read the question again carefully. *
Your answer
Answer:
I divided 213 and 7 and the answer was 30.4. So the answer is 30 rafts.
Step-by-step explanation:
Divide the 2 numbers..... 213/7=30.42855714
Round the decimal to the nearest tenth..... 30.4
Round 30.4 to the nearest whole..... 30
I hope I've helped! Please leave a Vote and Thanks!
Final answer:
The smallest number of rafts the water park needs for 213 guests waiting in line is 31.
Explanation:
To determine the smallest number of rafts needed for 213 guests, we divide the total number of guests by the maximum number of people that can ride a raft at one time.
Dividing 213 by 7, we get a quotient of 30 and a remainder of 3.
Since we cannot have a partial raft, we need to add another raft to accommodate the remaining 3 guests. Therefore, the smallest number of rafts the water park needs is 31.

Upon evaluating each equation, it is determined that options B (-5x + 12 = 5x - 5) and C (-5x + 12 = -12x - 12) are the ones that have exactly one solution, while options A and D have no solutions.
Explanation:To determine which of the given equations have exactly one solution, we can analyze each equation individually:
A. -5x + 12 = 5x + 12: Both sides of the equation are equal except for the opposite signs of the x terms. This means that, no matter what value x takes, the x terms will cancel each other out, making the equation incorrect. Hence, this equation has no solutions.B. -5x + 12 = 5x - 5: The x terms here can be moved to one side and the constants to the other. Adding 5x to both sides gives -5x + 5x + 12 = 5x + 5x - 5, simplifying to 12 = 10x - 5. Thus, this equation can be solved for x, indicating it has exactly one solution.C. -5x + 12 = -12x - 12: Again, we move all x terms to one side and the constants to the other to get -5x + 12x = -12 - 12, simplifying to 7x = -24. Solving for x, we get x = -24/7, indicating that this equation also has exactly one solution.D. -5x + 12 = -5x - 12: In this equation, the x terms are identical on both sides, meaning they will cancel out, leaving us with 12 = -12, which is never true. Hence, this equation has no solutions.From this analysis, we see that options B and C have exactly one solution.
