Answer:

As below

Step-by-step explanation:

we want to know  how long it took to fly  so make two equations and set them equal to each other using the variable t

so, use  d = r*t   where d= distance , r= rate ( speed) and t = time  

w= wind velocity (speed with direction)

1500=(w+550)*t

1000=(-w+550)*t

now make both equations with respect to t

1500/(w+550) = t

1000/(-w+550) = t

since they are both equal to t,  where t is the same amount of flying time, set the two equations equal to each other

1500/(w+550) = 1000/(-w+550)

now solve for w

1500w + 825,000 = -1000w+550,000

2500w= -275,000

w = - 110

the wind speed is 110 opposite of the planes direction but also, if the plane flies in the other direction with it.  

wind velocity (velocity is speed with a direction )   is 110 MPH

they are asking for speed, b/c we don't know anything about direction... that is which direction is the plane headed during it's flight therefore we also can't say anything about the   wind direction either.  :|

6 out of 30 or 1/5 which is arrow A

Answer:

Slope: -2

y-intercept: -3 or (0, -3)

Step-by-step explanation:

y = mx + b

    m = slope

    b = y-intercept

6x+3y= -9

3y = -6x - 9

y = -2x - 3

Answer:

Step-by-step explanation:

[tex]s = slant[/tex]

[tex]h = \sqrt{s^{2} } - ( \frac{a}{2} ) ^{2}[/tex]

[tex]h = \sqrt{5^{2} } - ( \frac{6}{2} ) ^{2}[/tex]

[tex]h = \sqrt{5^{2} } - 3^{2}[/tex]

[tex]h=[/tex] 4

Answer:

84cm^2

Step-by-step explanation:

P=2l+2w

We are given,

P=40cm

l=2w+2

Plug these into the first formula and solve for the dimensions,

length and width, of the rectangle:

40=2(2w+2)+2w              Simplify

40=4w+4+2w

40=6w+4

36=6w

6=w OR the width is 6cm, therefore,

the length is

l=2(6)+2

l=14cm

To calculate the area of a rectangle, A=lw,

plug the length,14cm, and the width, 6cm, into this formula

A=(14)(6)

A=84cm2 OR the area of the rectangle is 84cm^2

Answer:

[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:

the value of the required slope can be calculated from:

[tex]s=\frac{y_1-y_2}{x_1-x_2};[/tex]

[tex]s=\frac{10-8}{2-5};[/tex]

finally,

[tex]s=-\frac{2}{3}.[/tex]

Note, the suggested option is not the only one.

Answer:

6(7a + 9b) = 3(14a + 18b)

Step-by-step explanation:

We need to find the equivalent expression for the given expression i.e. 6(7a + 9b).

We can use the distributive property here such that,

a(b+c) = ab + ac

We have, a = 6, b = 7 and c = 9

6(7a + 9b) = 6(7a) + 6(9b)

= 42a + 54b

or taking 3 common from the above expression.

= 3(14a+18b)

Hence, the correct option is (a).

Answer:

8.85

Answer:

35 square cm

Step-by-step explanation:

Square area: 5 cm x 5 cm = 25 square cm.

Triangle area: 4 cm x 5 cm / 2 = 10 square cm.

25+10=35 square cm.

Answer:

0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Tested negative

Event B: Does not carry an abdornal CF gene.

Probability of a negative test:

10% of 1/25 = 0.04 = 4%

100% of 100 - 4 = 96%. So

[tex]P(A) = 0.1*0.04 + 1*0.96 = 0.964[/tex]

Negative test and not carrying an abdornal gene:

100% of 96%. So

[tex]P(A \cap B) = 1*0.96 = 0.96[/tex]

Compute the probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.96}{0.964} = 0.9959[/tex]

0.9959 = 99.59% probability that a randomly chosen person of European ancestry does not carry an abnormal CF gene given that he /she tested negative.
