Answer:

1.01 m/s

Step-by-step explanation:

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

t = Time

[tex]s_y[/tex] = Displacement in y direction = 1.2 m

[tex]s_x[/tex] = Displacement in x direction = 0.5 m

[tex]v_x[/tex] = Velocity in x direction

Displacement in y direction is given by

[tex]s_y=u_yt+\dfrac{1}{2}at^2\\\Rightarrow t=\sqrt{\dfrac{2s_y}{a}}\\\Rightarrow t=\sqrt{\dfrac{2\times 1.2}{9.81}\\\Rightarrow t=0.4946\ \text{s}[/tex]

[tex]s_x=v_xt\\\Rightarrow v_x=\dfrac{s_x}{t}\\\Rightarrow v_x=\dfrac{0.5}{0.4946}\\\Rightarrow v_x=1.01\ \text{m/s}[/tex]

The ball was rolling with a speed of 1.01 m/s.

Answer:

Step-by-step explanation!

width = w

length = w + 15

So: w(w + 15) =1250 square feet

w^2 + 15w = 1250

Next you do: w^2+15w-1250=0

Then you use the quadratic formula to factor.

Answer:

Prob ( 2nd Red 'given' 1st Blue ) = 0.8  = 4/5

Step-by-step explanation:

Prob ( A I B ) = Prob (A ⋂ B) / P (B)

Prob ( 2nd Red 'given' 1st Blue ) = P ( 2nd Red & 1st Blue ) / P ( 1st blue)

P ( 1st blue & 2nd red ) = 32/128 , P ( 1st blue ) = 5/16

So, P ( 2nd Red I 1st Blue ) =  ( 32 / 128 ) / ( 5/16 )

= 0.8 = 4/5

Answer:

4/5

Step-by-step explanation:

Answer:

Step-by-step explanation:

4w + 2L = 670

2w + L = 335

L = 335 - 2w

Area A(w) = w(335 - 2w)

max occurs at the average of the solutions.

solutions are w=0 and w = 167.5

the average is 83.75

83.75 * (335 - 2 * 83.75) = 14028.125

Answer:A

Step-by-step explanation:

Answer:

The absolute difference between the two calculations is 0.2

Step-by-step explanation:

Student 1

When the events do not affect each other, they are known as independent events. That is, two events are independent if the result of the second event is not affected by the result of the first event.

When two events are independent, the probability that A and B occur is equal to the product of the probability that A occurs and the probability that B occurs. Then:

P(A∩B)= P(A)*P(B)

The probability of the opposite event is equal to 1 minus the probability of the  event. So in this case you have:

P(A'∩B')= 1 - P(A∪B)

Being P(A∪B)= 0.7, then:

P(A'∩B')= 1 -0.7

P(A'∩B')= 0.3

Being P(A)= 0.5 and P(A'), so

0.3= 0.5*P(B)

[tex]P(B')=\frac{0.3}{0.5}[/tex]

P(B')=0.6

Being P(B)= 1 - P(B') so P(B)= 1 - 0.6 and you get P(B)=0.4

Student 2

Two events are mutually exclusive when both cannot occur simultaneously. In other words, two events A and B are incompatible or mutually exclusive when they have no element in common. This is: P(A∩B)= 0

Being P(A∪B) =P(A) + P(B) - P(A∩B), P(A)=0.5 and P(A∪B)= 0.7, you get:

0.7=0.5 + P(B) -0

Solving:

0.7=0.5 + P(B)

0.7 - 0.5 = P(B)

0.2 = P(B)

Finally the absolute difference between the two calculations can be calcutated as:

|0.4 - 0.2|= 0.2

The absolute difference between the two calculations is 0.2

Answer:

The left hand is more accurate.

Step-by-step explanation:

If you look at the graph, it will look like the right hand is more accurate, due to the fact that it has a closer distance than the left. However, the right hand actually never have hit the target while the left did more than once.

Step-by-step explanation:

Answer:

6.144

Step-by-step explanation:

Given the expression

5ln(4t) = 16

Required

Solve for t

5ln(4t) = 16

Divide both sides by 5

5ln(4t)/5 = 16/5

ln(4t) = 3.2

Apply exponent to both sides of the equation

e^ln(4t) = e^3.2

4t = e^3.2

4t = 24.53

t = 24.53/4

t = 6.144

The value of t is 6.144

Answer: 160

Step-by-step explanation: 20% of 160 is 32. 100% of 160 is 160, therefore 20 percent of 160 equals 32.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Assuming that we are only trying to calculate the probability of the light being green ONLY on day 4 then it would be the exact same probability as every other day, which would be 17%. Now if we are trying to calculate the probability of the light being green on the first consecutive 4 days then we would need to multiply this probability (in decimal form) four times for the four days like so...

0.17 * 0.17 * 0.17 * 0.17 = x

0.00083521 = x   ... times by 100 to get percentage

0.00083521 * 100 = 0.0835%

So the probability of the light being green 4 days in a row during your commute is 0.0835%

It has exactly two zeros .

f (x) = x^2 + 0x + 0 is it's extended form so I think the answre is number B.

Step-by-step explanation:

Answer: 0.19158

Step-by-step explanation:

Given: An undergraduate class has 24 biology majors and 17 chemistry majors.

Total students needs to be selected = 8

Number of ways to select 8 students out of 41= [tex]^{41}C_8[/tex]

Number of ways to select exactly two chemistry majors (i.e. rest 6 will be biology majors) = [tex]^{24}C_6\times ^{17}C_2[/tex]

Required probability = [tex]\dfrac{^{24}C_6\times ^{17}C_2}{^{41}C_8}[/tex]

[tex]=\dfrac{\dfrac{24!}{6!(24-6)!}\times\dfrac{17!}{2!(17-2)!}}{\dfrac{41!}{8!(41-8)!}}\\\\=\dfrac{134596\times136}{95548245}\\\\= 0.19158[/tex]

The probability of choosing exactly two chemistry majors = 0.19158

Answer:

180 ft

Step-by-step explanation:

We are told that the scale model is 40:1. And that it's being used to conduct wind - tunnel tests.

This means 40 units represents 1ft.

This means that 4.5ft will be;

(4.5 × 40)/1 = 180 ft

Thus, the actual length of airplane would be 180 ft.

Answer:

Since AB  = AC  ....the angles opposite these sides are also equal...

So   y   =    [ 180 - 24 ] / 2   =  156 /  2    =   78°
