Answer:

the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821

Step-by-step explanation:

Given that;

years a Mars rover is expected to function on the surface of Mars λ = 0.25

probability that it will be working for an additional 10 years after it last sent a communication to mission control?

Now x is number of years a Mars rover function

f(x) = 0.25e^-0.25x , 0 < n < ∞

so

P( X>10 ) = ₁₀∫^∞ 0.25e^(-0.25n) dn

= e^(-0.25 × 10)

= e^(-2.5})

= 0.0821

therefore the probability that it will be working for an additional 10 years after it last sent a communication to mission control is 0.0821

Answer:

B. 1,251 ft²

Step-by-step explanation:

The walkway can be divided into 4 rectangles as shown in the attachment below.

Calculate the area of the walkway part by part.

Part 1 and Part 2:

Length = 100 ft + 4½ ft + 4½ ft = 109 ft

Width = 4½ ft

Area of part 1 and 2 = 2(length * width)

= 2(109*4½) = 981 ft²

Part 3 and Part 4:

Length = 30 ft

Width = 4½ ft

Area of part 1 and 2 = 2(length * width)

= 2(30*4½) = 270 ft²

Area of the walkway = 981 + 270 = 1,251 ft²

Answer:

y=-1x-1

Step-by-step explanation:

m=y2-y1/x2-x1

(-3)-1=-4

2-(-2)=4

-4/4=(-1)

y=mx+b

-3=-1(2)+b

-1*2=-2

-2-(-2)=0

(-3)-(-2)=(-1)

b=-1

Answer:

30%

Step-by-step explanation:

Answer:

The correct option is A.

Step-by-step explanation:

The formula to compute the expected value is:

[tex]E(X)=\sum x\cdot P(X)[/tex]

The information provided can be summarized as follows:

              X         P (X)

Win     $107       1/21

Lose     -$5       20/21

Compute the value of expected winning as follows:

[tex]E(X)=\sum x\cdot P(X)[/tex]

          [tex]=(107\times\frac{1}{21})+(-5\times\frac{20}{21})\\\\=\frac{107}{21}-\frac{100}{21}\\\\=\frac{107-100}{21}\\\\=0.33333333\\\\\approx \$0.33[/tex]

Thus, the value of expected winning is $0.33.

The correct option is A.

No

Step-by-step explanation:

The wall straight up is one of the legs of the triangle.  That makes the hypotenuse the ladder which is 50 feet.  The hypotenuse needs to be the longest side, but the height of the wall is the longest, so the ladder will not reach the top.

Answer:

  F20 = 15985k -20361g

Step-by-step explanation:

If we assume F3 and F4 are the third and fourth terms of an arithmetic sequence, the common difference is ...

  d = F4 -F3 = (945k -713g) -(5k +515g)

  d = 940k -1228g

Then the 20th term is ...

  F20 = F3 +(20 -3)d = (5k +515g) +17(940k -1228g)

  F20 = 15985k -20361g

Answer:

30 kids are present

Step-by-step explanation:

Hey there champ! Basically you wanna divide 40 by 4, or the fraction 1/4 to get the number of kids absent which is 10. From here you subtract 10 from your og class size, 40 and get thirty! Have a great day :)

D

Step-by-step explanation:

Answer:

So... for problem 15. im gonna help you and maybe you'll understand how to do it:) So the X axis is the horizontal line and the Y axis is the vertical line.

So when it says X -4

                          Y 5

Then the point would be at -4 on the horizontal line and 5 positive points on the Y axis (vertical line)

Answer:

The width of the confidence interval is going to be wider

Step-by-step explanation:

When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;

The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.

This answers your question.

Step-by-step explanation:

Answer:

BD = 9

Step-by-step explanation:

Since, the points B, C D and E all lie on the same line segment, in that order, such that the

ratio of BC:CD: DE is equal to 1:2:2. If BE = 15

Let BC = x, CD = 2x, DE = 2x

[tex] \because BC+CD+ DE= BE\\\\

\therefore x + 2x + 2x = 15..(\because BE =15)\\\\

\therefore 5x = 15\\\\

\therefore x = \frac{15}{5}\\\\

\therefore x = 3\\\\

\because BD = BC + CD\\\|

\therefore BD = x + 2x \\\\

\therefore BD = 3x\\\\

\therefore BD = 3\times 3\\\\

\huge \orange {\boxed {\therefore BD = 9}} [/tex]
