Answer:

The probability that a terminal will last 5 years or less is 0.8413

Step-by-step explanation:

Given:

μ= 4 years

σ= 1 year

Z=(x-μ)÷σ

Z=(5-4)÷1 = 1

The standard normal distribution table provides the probability that a normally distributed random variable Z, with mean equal to 0 and variance equal to 1, is less than or equal to z.

For z= 1 ⇒ P(z≤1)=0.8413

F(x)=−2x+16<br> g(x)=4x+10<br> please give me the intersection points
vagabundo [1.1K]

Answer:

  • (1, 14)

Step-by-step explanation:

The intersection is when both functions have same coordinates

  • f(x) = g(x)

Substitute to get

  • - 2x + 16 = 4x + 10
  • 4x + 2x = 16 - 10
  • 6x = 6
  • x = 1

The y- coordinate is

  • y = - 2(1) + 16 = -2 + 16 = 14

So the intersection point is (1, 14)

Say the fraction in unit form. 1/10
Anni [7]

Answer:

One tenth

Step-by-step explanation:

You state the number on top as is.

Numerator:

1 - one

2- two

and so on.

over the denominator

which you state as an ordinal number

2 = halves

3 = thirds

4 = fourths

5 = fifths

etc.

so 1/10 would be one over tenths but you say  one tenth.

Need help on graphing problem
aivan3 [116]
J is your answer.

Slope is rise over run + your Y intercept.

Your y- intercept is the point in the graph in which the line passes through, the line passes through -2, so you know -2 is going to be your answer at the end. And slope is rise/run.

From one point to another, you rise 1 time , and run over 3 so you know your answer is

y = 1/3x - 2

hope this helps :)

Is this correct? I used the 90/360 x 2 π (90)
slavikrds [6]

The circumference is found by multiplying the radius by pi by 2

And then the arc length would be multiplied by the fraction of the circle..

So using what you wrote is correct, but the answer you got is incorrect.

2x 3.14 x 90 = 565.2 meters

565.2 x 90/360 = 141.3 meters
