A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study 620 babies were born, and 341 of them were girls. Use the sample data to construct a 99% confidence interval estimate of the percentage of girls born. Based on the result, does the method appear to be effective?
Answer:
Based on the confidence interval, the method appears to not bring expected results
Step-by-step explanation:
The given parameters are;
The number of babies in the study, n = 620 babies
The number of girls in the study sample = 341 girls
The proportion of girls in the study sample, [tex]\hat p[/tex] = 341/620 = 0.55
At 99% confidence level, we have the critical z = 2.576;
The confidence interval is given by the following formula;
[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p} \cdot (1-\hat{p})}{n}}[/tex]
Plugging in the values of the variables, we get;
[tex]CI=0.55\pm 2.576\times \sqrt{\dfrac{0.55 \times (1-0.55)}{620}} \approx 0.55 \ \pm 5.14680 \times 10^{-2}[/tex]
Therefore, 0.498532 < p < 0.601468
Based on the result of the confidence interval, we can be 99% sure that the true mean is between 0.498532 and 0.601468, therefore, given that the range includes a true mean of 0.5 or 50% probability of conceiving a girl, which is the percentage predicted by genetics, the method appears ineffective

Ellen has a bag with 3 red marbles and 2 blue marbles in it. She is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. 3 red marbles and 2 blue marbles What is the best prediction for the number of times that Ellen will draw a blue marble?
Answer:
120
Step-by-step explanation:
Blue marbles = 2
Red marbles = 3
Total marbles = 2 + 3 = 5
If a marble is drawn 300 times ;prediction for the number of times a blue marble will be drawn :
P(drawing a blue marble) = number of blue marbles / total number of marbles
= 2 /5 = 0.4
Predicted number of times blue is drawn in 300 selections :
300 * 0.4 = 120
Approximately 120 times

What is the value of x?
Answer:
x=12
Step-by-step explanation:
All of the arcs have central angles.
Arc UR central angle is 10x.Arc RS central angle is x+61Arc ST central angle is x+63Arc TU central angle is x+80.Since an arc's central angle measure equal the arc measure,
Arc UR measure 10xArc RS measure x+61Arc ST measure x+63Arc TU measure x+80A circle measures 360 degrees so all the arcs added up will equal 360
[tex]10x + x + 61 + x + 63 + x + 80 = 360[/tex]
[tex]13x + 204 = 360[/tex]
[tex]13x = 156[/tex]

While shopping at a clearance sale, Samantha finds a $60.00 dress on sale for 25% off. Samantha also has a 50% off
coupon. Which statement correctly summarizes her savings?
It seems most likely that ...
... Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction
_____
In the real world, it seems probable that Samantha will be offered the choice of using the coupon or the sale discount. If she chooses tht 50% coupon, her savings will be $30. If she chooses the marked sale discount, her savings will be $15.
The scenario above assumes she gets 50% off the sale price of $45, so saves $15+22.50 = $37.50 off the original price.
Answer:
The answer is B. (Samantha will save $37.50 because she must first find the 25% sale price before taking the extra 50% reduction.)

Lisa wants to buy a snowboard that is on sale for 30% off the original price of $180. If the sales tax in Lisa's state is 6%, how much will Lisa pay for the snowboard?
Answer:
$133.56
Step-by-step explanation:
Multiply 180 and .3 and then subtract that number with 180
you should then get 126
multiply 126 by .06 you should get 7.56
Finally add 126 and 7.56 you should get your final price of 133.56

Step-by-step explanation:
9 16/14 9 turns to 8 and u add 14/14 to 2/14 16/14 then subtract 5/14
-4 5/14
4 11/14
Answer:
5 4/14
Step-by-step explanation:
Ok so what we do is take the whole number away from the fractions (9 - 4)
And subtract the fractions
9/14 - 5/14 = 4/14 just remember NEVER ADD OR SUBTRACT DENOMINATORS. Now you should add the whole numbers 9 - 4 =5 now get them together 5 4/14. Theirs your answer

Your friend incorrectly factors the expression 15x - 20xy as 5x (3 - 4xy). What error did your friend likely make?
A. Your friend did not factor the variable from the second term.
B. Your friend did not have the correct operation inside the parentheses.
C. Your friend did not factor the variable from the first term.
D. Your friend did not simplify the terms inside the parentheses.
Answer:
A. Your friend did not factor the variable from the second term.
Step-by-step explanation:
15x - 20xy
Your friend was correct in factoring out 5x. However, when you factor out a component from an expression, you have to change each component in the expression.
This means that factoring out 5x will result in: 5x(3 - 4y).
Therefore, your answer is:
A. Your friend did not factor the variable from the second term.
Hope this helps!

Me he gastado, primero, la mitad de lo que llevaba, despues, la mitad de lo que me quedaba. Que fraccion del total me he gastado
Answer:
Me ha quedado una cuarta parte de la cantidad inicial, es decir, me he gastado tres cuartas partes de la cantidad inicial comprando crustácea importada en la pescadería y marisquería.
Step-by-step explanation:
Asumamos que hacemos la compra en una pescadería y marisquería. Si la razón inicial equivale a 1, gasta inicialmente la mitad de la razón inicial, luego gasta la mitad de la razón resultante. El gasto se entiende como una forma de sustracción mientras que la sucesión como una multiplicación. Por consiguiente, tenemos el siguiente producto:
[tex]c = \left(1-\frac{1}{2} \right)\cdot \left(1-\frac{1}{2} \right)\cdot c_{o}[/tex]
[tex]c = \frac{1}{4}\cdot c_{o}[/tex]
Donde [tex]c_{o}[/tex] es la cantidad inicial.

Parallel Lines
How do you know two lines are parallel?
Determine if any of the sets of lines are parallel. Justify your answer.
Line a passes through (-2, 4) and (3, 14).
Line b passes through (7, 2) and (-1, 3).
