A traffic light is green for 2 minutes, red for 40 seconds, and yellow for 10 seconds. When a car approaches the light, what is
the probability that it is not red?

Answer:

your answer will be 3.4

Step-by-step explanation:

n=number of terms

{6,5,10,11,13}=5

also ∑(x-x)^2=46

[tex]S=\sqrt{\frac{1}{5-1} *46} =[/tex]

[tex]\sqrt{\frac{46}{4} }=\sqrt{11.5} \\\\S=3.4[/tex]

hope it helps

have a great day!!

Answer:

Step-by-step explanation:

Answer:

200π cm^2

Step-by-step explanation:

Sb = 8^2 π = 64π cm^2

a = sqrt2 [8^2 + 15^2] = sqrt2 [64 + 225] = sqrt (289) = 17 cm

Sl = 8x17xπ = 136 π cm^2

SA = 136π + 64π =200π cm^2

Hope it  helps you

I tried a lot on this

Answer:

70

Step-by-step explanation:

2x(3x5)=15            15x0.5=7.5            7.5+7.5=15

2x(5x11)=55

55+15=70

That sounds horrible

Answer:

Mode is 20.

Step-by-step explanation:

Mode is the value or values in the data set that occurs most frequently.

{12, 12.50, 13, 18.50, 20, 20}

20 is the number that occurs most frequently.

Answer:

6216

Step-by-step explanation:

This problem deals with exponential growth.

Final value: F

Present (initial) value: P

Rate of growth: r

Time in years = t

[tex] F = P(1 + r)^t [/tex]

[tex] F = 2900(1 + 0.1)^8 [/tex]

[tex] F = 6216 [/tex]

Answer: 6216

Answer:

Step-by-step explanation:

a) 2,35 x 10^9

b) 2,5 x 10^7

c) 9 x 10^4

Answer:

The angels are 60 degrees and 120 degrees

Step-by-step explanation:

The sum of two supplementary angels equal 180 degrees.

So, lets look at the ratio: 6:3

We then add 6 and 3 together which gives us 9.

Then you put it in this equation:

9x = 180

x= 20

- You are adding the two numbers and dividing the sum by 180 because the answer will tell us how much 1 would equal.

- In this case, we multiply 20 by 6 = 120 degrees

- Then we multiply 20 by 3 = 60 degrees.

(We can check our answer by: 120 + 60 = 180 degrees) :)

Answer:

radius is 8cm

Step-by-step explanation: radius is half of diameter so 16/2= 8

Step-by-step explanation:

Answer:

[tex]\boxed {\boxed {\sf 2 \ hours}}[/tex]

Step-by-step explanation:

Let's set up a proportion to solve. Use the following setup:

[tex]\frac {hours}{miles}=\frac{hours}{miles}[/tex]

We know that it takes Oliver 4 hours to drive 278 miles.

[tex]\frac {4 \ hours}{278 \ miles}=\frac{hours}{miles}[/tex]

We don't know how long it takes him to drive 139 miles. Therefore, we use the variable x for hours, because it is unknown.

[tex]\frac {4 \ hours}{278 \ miles}=\frac{x \ hours}{139 \ miles}[/tex]

[tex]\frac {4 }{278 }=\frac{x \ hours}{139 }[/tex]

We are solving for x, the hours it takes him to drive 139 miles. The variable must be isolated. It is being divided by 139 and the inverse of division is multiplication. Multiply both sides of the equation by 139.

[tex]139*\frac {4 }{278 }=\frac{x \ hours}{139 }*139[/tex]

[tex]139*\frac {4 }{278 }={x }[/tex]

[tex]2=x[/tex]

It takes Oliver 2 hours to drive 139 miles.

Answer:

60 seconds

Step-by-step explanation:

The y-intercept is 60

Answer:

Original slope = 4

Parallel Slope = 4

Equation = y = 4x - 16

Step-by-step explanation:

y = 4x +8

* the slope is the same since it is parallel

2=4(4) + b

2=16 + b

-14=b

y = 4x - 16

Step-by-step explanation:

(−3)(+8)

Answer:

[tex]K=6[/tex]

Step-by-step explanation:

In f(x) graph the vertex is at x=4

In g(x) the vertex at x=-2

so, the graph is shifted 6 units left. when the graph is shifted k units left then f(x) becomes f(x+k)

here the  graph is 6 units left so.. K= 6

Answer:

(4,10)

Step-by-step explanation:

   8x - 5y = -18

+  2x + 5y = 58

10x = 40

Dive both sides by 10.

x = 4

2x + 5y = 58

2(4) + 5y = 58

8 + 5y = 58

5y = 50

y = 10

Step-by-step explanation:

The [tex]f(x) = x^2 + 4[/tex] model is developed in the interval [tex](-2, 2)[/tex] total equal in a between such a range[tex]= 5[/tex].

Its right endpoint of every rectangle is separated onto n equal parts by the height [tex]= \frac{5}{n}.[/tex]

Height of endpoint [tex]= \frac{5}{n}[/tex] of the k rectangles therefore, the height of the kth rectangle = First rectangle height + K rectangle height

[tex]= -2 +k \times \frac{5}{n}\\\\[/tex]
