Answer:

Present afe of Payal = x yrs.

Therefore, according to question,

Present age of Arav = x/3 yrs.

After 12 yrs.,

Age of Payal = (x+12) yrs.

Hence, we have,

Age of Aarav = [(x/3)+12] yrs.

A small hexagon was graphed on a coordinate plane. By what scale factor was the hexagon dilated to create the larger hexagon?

suter [353]

Consider the point where the hexagons meet the positive half of the y axis.

The inner hexagon meets the axis at $y=4$ , whereas the outer hexagon meets the axis at $y = 6$

So, we're looking for a dilation constant $k$ such that

$4k = 6$

So, solving by k we have

$k = \dfrac{6}{4} = \dfrac{3}{2}$

Given sin 0 and angle 0 is in Quadrant II, what is the exact value of cos 0 in

Anna007 [38]

sin = 3/7

1 = sin²0 + cos²0

cos²0 = 1 - 9/49

cos²0 = 40/49

cos0 = √(40) / 7

since its in Quadrant 2 the sin is positive and cos is negative

cos0 = - √(40) / 7

The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (computed using the same sample data) for μ = true

kenny6666 [7]

Answer:

115.3 hertz

Step-by-step explanation:

For either interval, the value of the sample mean is given by the average of the lower and upper bound of the confidence interval. Since both intervals were constructed by using the same sample, both values should be equal.

For the first interval:

$M=\frac{114.9 + 115.7}{2} \\M=115.3\ hertz$

For the second interval:

$M=\frac{114.6 + 116.0}{2} \\M=115.3\ hertz$
