Find the measure of arc BC.
Answer: A 129
Step-by-step explanation:
Because the 2 chords are the same (lines in the circle), the 2 arcs are the same create an equation that makes them equal
3x+24 = 4x -11 >bring x to one side by subtracting both sides by 3x
24 = x -11 > add both sides by 11
35 = x
Now that we have solved for x you need to plug that back into the equation for BC
BC= 4x-11
BC = 4(35) - 11
BC = 140 - 11
BC = 129 >A
The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 23.5 for a sample of size 775 and standard deviation 12.2. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% confidence level). Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
The 95% confidence interval for the effectiveness of the blood-pressure drug is given as follows:
\(22.6 < \mu < 24.4\)
How to obtain the confidence interval?The mean, the standard deviation and the sample size for this problem, which are the three parameters, are given as follows:
\(\overline{x} = 23.5, \sigma = 12.2, n = 775\)
Looking at the z-table, the critical value for a 95% confidence interval is given as follows:
z = 1.96.
The lower bound of the interval is then given as follows:
\(23.5 - 1.96 \times \frac{12.2}{\sqrt{775}} = 22.6\)
The upper bound of the interval is then given as follows:
\(23.5 + 1.96 \times \frac{12.2}{\sqrt{775}} = 24.4\)

Ali completed 1/3 of her homework on Friday and 1/4 of her homework on Saturday. She told her mother she is almost done. Is she correct? Please explain your answer.
Answer:
Yes, she is almost done
Step-by-step explanation:
We can find the common denominator of these fractions, then add them.
1/3=4/12
1/4=3/12
Then we add the two, and round it up either up or down, depending if it is above 1/2. 6/12 is equal to 1/2, and 4/12+3/12 is 7/12 which is greater than 1/2, so she is almost done.

A certain disease has an incidence rate of 0.7%. If the false negative rate is 7% and the false positive rate is 4%, compute the probability that a person who tests positive actually has the disease.
Given:
The incidence rate of 0.7%.
The false-negative rate is 7%.
The false-positive rate is 4%.
To find:
The probability that a person who tests positive actually has the disease.
Explanation:
Here, we have,
\(\begin{gathered} P\mleft(disease\mright)=0.007 \\ P\mleft(Positive|disease\mright)=1-\text{False negative rate} \\ =1-0.07 \\ =0.93 \end{gathered}\)Let us find the probability of no disease.
\(\begin{gathered} P(no\text{ }disease)=1-P(disease) \\ =1-0.007 \\ =0.993 \end{gathered}\)And since the false positive rate is 4%,
\(\begin{gathered} P(Positive|no\text{ }disease)=\text{False positive rate} \\ =0.04 \end{gathered}\)Using Bayes's theorem,
\(P(disease|positive)=\frac{P(disease)\cdot P(positive|disease)}{P(disease)\cdot P(positive|disease)+P(no\text{ }disease)\cdot P(positive|no\text{ }disease)}\)On substitution we get,
\(\begin{gathered} P(disease|positive)=\frac{(0.007)(0.93)}{(0.007)(0.93)+(0.993)(004)} \\ =\frac{0.00651}{0.00651+0.03972} \\ =\frac{0.00651}{0.04623} \\ =0.14081 \\ \approx0.141 \\ =14.1\text{ \%} \end{gathered}\)Final answer:
The probability that a person who tests positive actually has the disease is 0.141 or 14.1%

As a result, the rectangle's perimeter is 230 cm as the rectangle's base has a 69 cm width.
what is rectangle ?Four straight sides that are aligned and equal in length make up a rectangle, a two-dimensional geometric object. A rectangles has four right-angled angles (90 degrees). A rectangle can be thought of as a quadrilateral with all angles equal to 90 degrees, or as a trapezoid with two pairs of parallel sides. By multiplying the rectangle's length and breadth, the area of the rectangle may be determined. By summing the measurements of all four sides, one may get a rectangle's perimeter. In many commonplace items like window, book covers, and screens, rectangles are frequently used.
given
According to the information provided, the rectangle's base has a 69 cm width.
We also know that the height is equal to the base by two thirds. As a result, the rectangle's height can be determined as follows:
Height equals 2/3 of base height, or 69 cm.
size = 46 cm
Knowing the rectangle's base and height, we can use the following formula to get its perimeter:
P = 2l + 2w
P = 2(69 cm) + 2(46 cm) (46 cm)
P = 230 cm if P = 138 cm plus 92 cm.
As a result, the rectangle's perimeter is 230 cm as the rectangle's base has a 69 cm width.

Write an equation of the line that passes through (6, 1) and is perpendicular to x +2y-12=0.
Answer:
y = 2x - 11
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes—multiplying the slopes of two lines results in a product of -1.
Given the linear equation, x + 2y - 12 = 0, and the other point, (6, 1):
Convert the given linear equation into its slope-intercept form:
x + 2y - 12 = 0
Subtract x from both sides:
x - x + 2y - 12 = - x 0
2y - 12 = -x
Next, add 12 to both sides of the equation:
2y - 12 + 12 = -x + 12
2y = -x + 12
Divide both sides by 2 in order to isolate y:
y = - ½x + 6
Since the slope of the given equation is - ½, then the other line perpendicular to it must have a slope of 2:
Let m₁ = - ½
m₂ = 2
m₁ × m₂ = -1
-½ × 2 = -1
Hence, the slope of the other line, m₂ = 2. Next, using the slope of the other line, m₂ = 2, and the other given point, (6, 1), substitute these values into the slope-intercept form to solve for the y-intercept, (b):
y = mx + b
1 = 2(6) + b
1 = 12 + b
1 - 12 = 12 - 12 + b
-11 = b
Thus, the y-intercept of the other line is b = -11.
Therefore, the linear equation of the line that is perpendicular to x + 2y - 12 = 0 is:
y = 2x - 11.As a proof, attached is the graph of both equations, where it shows that they are perpendicular from each other.
