Answer:

0.0021

Step-by-step explanation:

Given:

Probability of ordering a nonalcoholic beverage is, P(N)=0.46

Number of samples are n=10

Now, the complement of event 'N' is not ordering a nonalcoholic beverage.

Therefore, P(\overline N)=1-P(N)=1-0.46=0.54

Now, for a sample of '10' customers, the probability of not ordering a non alcoholic beverage is product of their individual probabilities as all these events are independent events.

Therefore, probability that none of the 10 will order a nonalcoholic beverage is given as:

=[P(\overline N)]^{10}\\\\=(0.54)^{10}\\\\=0.0021

Verify that the given point is on the curve and find the lines that are (a) tangent and (b) normal to the curve at the given poi
lara [203]

For each curve, plug in the given point (x,y) and check if the equality holds. For example:

(I) (2, 3) does lie on x^2+xy-y^2=1 since 2^2 + 2*3 - 3^2 = 4 + 6 - 9 = 1.

For part (a), compute the derivative \frac{\mathrm dy}{\mathrm dx}, and evaluate it for the given point (x,y). This is the slope of the tangent line at the point. For example:

(I) The derivative is

x^2+xy-y^2=1\overset{\frac{\mathrm d}{\mathrm dx}}{\implies}2x+x\dfrac{\mathrm dy}{\mathrm dx}+y-2y\dfrac{\mathrm dy}{\mathrm dx}=0\implies\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{2x+y}{2y-x}

so the slope of the tangent at (2, 3) is

\dfrac{\mathrm dy}{\mathrm dx}(2,3)=\dfrac74

and its equation is then

y-3=\dfrac74(x-2)\implies y=\dfrac74x-\dfrac12

For part (b), recall that normal lines are perpendicular to tangent lines, so their slopes are negative reciprocals of the slopes of the tangents, -\frac1{\frac{\mathrm dy}{\mathrm dx}}. For example:

(I) The tangent has slope 7/4, so the normal has slope -4/7. Then the normal line has equation

y-3=-\dfrac47(x-2)\implies y=-\dfrac47x+\dfrac{29}7

find (a) the area and (b) the circumference of each circle using π=3.14. Round to the hundredths' place. 1. the diameter of the
Arada [10]

area = pi x r^2

circumference = 2x pi x r or pi x d

1st one diameter = 9.5 cm

so radius = 9.5/2 = 4.75

area = 3.14 x 4.75^2 = 70.85 square cm

circumference = 3.14 x 9.5 = 29.83 cm


2nd one radius = 4

area = 3.14 x 4^2 = 50.25 square cm

circumference = 2 x 3.14 x 4 = 25.12 cm

You can immediately see that the vertex is located at (-3,-2) and that the y-intercept is 7 or very close to 7.

The general equation for a parabola with vertex at (h,k) is 

y-k = (x-h)^2, and from that and the given info, we get:

y-(-2) = (x-(-3))^2, or  y+2 = (x+3)^2, or y = (x+3)^2 - 2.

\bf 60=10\sqrt{y-3}\implies \cfrac{60}{10}=\sqrt{y-3}\implies 6=\sqrt{y-3}

\textit{now, we simply raise both at }^2

(6)^2=(\sqrt{y-3})^2\implies 36=y-3\implies 36+3=y\implies 39=y
