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.)

Step-by-step explanation:

Given triangle in the picture is a right triangle.

By applying Pythagoras Theorem in this triangle.

(Hypotenuse)² = (Leg 1)² + (Leg2)²

(14)² = x² + 9²

x² = (14)² - 9²

[tex]x=\sqrt{196-81}[/tex]

[tex]x=\sqrt{115}[/tex]

x = 10.72

x  ≈ 10.7 ft.

An equation is a mathematical statement that two expressions are equal. The solution of an equation is the value that when substituted for the variable makes the equation a true statement. To achieve our goal, we use two principles of equality, the addition principle and the multiplication principle.

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

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.

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.

Answer:

x=12

Step-by-step explanation:

All of the arcs have central angles.

Since an arc's central angle measure equal the arc measure,

A 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]

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

y = 0 feet

Step-by-step explanation:

Given equation:

y = 25x

Where,

y = height (feet)

x = time (seconds)

25 = constant

Find the height of the elevator when the time is 0 seconds

y = 25x

y = 25(0)

y = 0 feet

Step-by-step explanation:

Area of Yellow Rectangle

Area = L * W

Area = 25 * 11

Area = 275

Area of Parallelogram

Area = Base * height

Area = 12 * 4

Area = 48

Area of shaded area

Area = rectangle - Parallelogram

Area = 275 - 48 = 227 square feet

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

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
