Answer:

42% of 91 is 38.22

Answer:

x - 2y = 4

Step-by-step explanation:

Parallel lines have equal slopes.

The given line has a slope of 1/2

so the required line is

y = -5 + (1/2) (x + 6)

Multiply by 2 on both sides,

2y = -10 + x + 6

so

x - 2y = 4

Answer:

The answer is B. -10 and E. 1

Step-by-step explanation:

Odds against = failures / successes

Probability = successes / (successes + failures)

0.21 = cats / (cats + no cats)

1 / 0.21 = (cats + no cats) / cats

4.76 = 1 + (no cats / cats)

3.76 = no cats / cats

So the odds against are 3.76 to 1.

There is insufficient information so the joint probability mass function of X and Y.

given that

there are three bowls they are a red bowl , a green bowl and a blue bowl  are on the kitchen table

alan places one egg into a randomly selected bowl.

X = # of eggs placed into the red bowl

Y = # of empty bowls at the end of the experiment.

the joint probability mass function of X and Y

1. Not sufficient

R=5

let us consider when G = 2 , B = 1 => P(G) = 2/8

when G=1, B=2 => P(G) = 1/8

2. Not Sufficient

P(B) = 1/3 = x/3x

But this doesn't tell us anything about B or total because P(B) = 1/3 , but it could also be 2/6 or 3/9 so on..

So we can have different B . Thus we can have different G combinations.

Together - Not Sufficient

P(B) = x/(3x) , R = 5

P(G) = 1- P( not G )

= 1- P(R or B)

But we cannot calculate this with out knowing P(R) and P(B).

we cannot solve this problem because there is no proper information is given.

The measure of the length EF of the triangle is; 21

We are given the the triangle BCD and we are told that;

E is the midpoint of BD.

F is the midpoint of CD

Now, since we have those midpoints, it means that by the concept of similar triangles, that;

DF/DC = EF/BC

Since F is the midpoint of DC, then it means that;

2DF = DC

We are given;

EF = 43 - 4x, and BC = 32 - 2x

Thus, we now have;

DF/(2DF) = (43 - 4x)/(32 - 2x)

1/2 = (43 - 4x)/(32 - 2x)

Cross multiply to get;

32 - 2x = 43 - 4x

4x - 2x = 43 - 32

2x = 11

x = 11/2

x = 5.5

Thus;

EF = 43 - 4(5.5)

EF = 43 - 22

EF = 21

Thus, we conclude that the side length EF is 21.

Step-by-step explanation:

We Know

The equation y = 3x - 2

Find the y coordinate (9, ?)

We just simply put 9 in for x and solve for y

y = 3(9) - 2

y = 18 - 2

y = 16

So, the coordinate are (9,16)

Answer:

180 degrees

Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

Reason:

Multiply each coordinate of D(-2,-4) by the scale factor 3 to get (-6, -12)

In other words, triple each coordinate of point D.

Answer: \(7.39466666\)

Step-by-step explanation:

Setting \(x=2.2\) and \(n=3\),

\(e^{2.2} \approx \sum^{3}_{k=0} \frac{2.2^{k}}{k!}=\frac{2.2^0}{0!}+\frac{2.2^1}{1!}+\frac{2.2^2}{2!}+\frac{2.2^3}{3!} \approx 7.39466666\)

Answer:

7.39466667 (8 d.p.)

Step-by-step explanation:

We can approximate the value of eˣ for any x using the following sum formula:

\(\boxed{e^{x} \approx \displaystyle \sum^n_{k=0}\dfrac{x^k}{k!}}\)

To approximate \(e^{2.2}\) with n = 3, substitute x = 2.2 and n = 3 into the given sum formula:

\(e^{2.2} \approx \displaystyle \sum^3_{k=0}\dfrac{2.2^k}{k!}\)

To calculate the sum, substitute k with each value from 0 to 3 and add the results together:

\(\begin{aligned}e^{2.2} &\approx \displaystyle \sum^3_{k=0}\dfrac{2.2^k}{k!}\\\\&= \dfrac{2.2^0}{0!}+\dfrac{2.2^1}{1!}+\dfrac{2.2^2}{2!}+\dfrac{2.2^3}{3!}\\\\&= \dfrac{1}{1}+\dfrac{2.2}{1}+\dfrac{4.84}{2}+\dfrac{10.648}{6}\\\\&= 1+2.2+2.42+1.774666666...\\\\&=7.39466667\; \sf (8\;d.p.)\end{aligned}\)

Therefore, the approximate value of \(e^{2.2}\) is:

\(\large \textsf{$e^{2.2}$}=\boxed{7.39466667}\; \sf (8\;d.p.)}\)

Note: To obtain a more accurate approximate value, increase the value of n.

The equation of the graph is:  \(y = 3.5 \cos(\frac{\pi }{3} x)\)

A sinusoidal graph is a type of graph that represents a periodic waveform, which oscillates back and forth over time.

The graph in the form of  \(y = a \cos(bx),\)

where, 'a' is amplitude and 'b' is period, follow these steps:

Amplitude: the graph oscillates between a maximum value (+3.5) and a minimum value (-3.5), both of which are equal to the amplitude.

So, a = 3.5

Period: To finding the period of the graph, see the mirror image across x axis and find x = ± 1.5 and we know for signal,

bx = π/2             (put x= 1.5)

b (1.5) = π/2

b = π/3

Therefore, we can put the values if a and b in general equation so, the graph equation is:

\(y = 3.5 \cos(\frac{\pi }{3} x)\)

The value of the double integral of y over D is 160.

The region D is defined as the image of the rectangle R under the transformation Φ(u,v) = (u², u+v). To find the integral of y over D, we need to express y as a function of u and v, and then compute the double integral in terms of u and v.

From the definition of Φ, we have:

u² = x

u + v = y

Solving for v in terms of u and y, we get:

v = y - u

Substituting this expression for v into the second equation, we get:

y = u + (y - u) = y

Therefore, y does not depend on u, and we can write:

y = f(v) = v + u

The integral of y over D can then be written as:

∫∫D y dA = ∫∫R f(v) |J| dA

where J is the Jacobian of the transformation Φ.

The Jacobian of Φ is given by:

J = ∂(x,y)/∂(u,v) =

| 2u 1 |

| 1 1 |

The determinant of J is:

|J| = 2u - 1

Substituting this expression for |J| and the expression for f(v) into the integral, we get:

∫∫D y dA = ∫∫R (v + u)(2u - 1) dudv

To evaluate this integral, we can integrate first with respect to u and then with respect to v:

∫∫D y dA = ∫[0,5]∫[1,9] (v + u)(2u - 1) dudv

= ∫[0,5] [(v+9)³/3 - (v+1)³/3] dv

= [(5+9)⁴/12 - (1+9)⁴/12]

= 480/3

= 160

Therefore, the value of the double integral of y over D is 160.
