Y=2x-5 is the equation of a straight line graph. Where does it cross the y-axis?

1 answer:

7 0

It would cross the y-axis at (0,-5)
the original equation is y=mx+b
y is the line as a whole
mx is the slope
b is the y intercept which means where the line crosses through the y-axis

Make predictions using experimental probability can someone explain this topic please

Gekata [30.6K]

You should multiply the experimental probability by the total number of trials in an actual experiment when making a prediction.

<h3>What is an experimental probability?</h3>

An experimental probability is also referred to as relative frequency or empirical probability and it can be defined as a ratio of the number of outcomes for the occurrence of a specific event to the total number of trials in an actual experiment.

In order to make a prediction by using experimental probability, you should multiply the experimental probability by the total number of trials in an actual experiment.

The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. (a) What is th

Sindrei [870]

Answer:

a) 0.0025

b) 0.9975

c) 23.03 minutes

d) 23.03 minutes

Step-by-step explanation:

Let X be the random variable that measures the time waited for a taxi.

If X is exponentially distributed with a mean of 10 minutes,then the probability that you have to wait more than t minutes is

$\large P(X>t) = e^{-t/10}$

1 hour = 60 minutes, so the probability that you wait longer than one hour is

$\large P(X>60)=e^{-6}=0.0025$

Due to the “memorylessness” of the exponential distribution, the probability that you have to wait 10 or less minutes after you have already waited for one hour, is the same as the probability that you have to wait 10 or less minutes

$\large P(X\leq 10)=1-e^{-6}=0.9975$

We want x so that

P(X>x)=0.1

$\large e^{-x/10}=0.1\rightarrow -x/10=ln(0.1)\rightarrow x=-10ln(0.1)=23.03\;minutes$

We want P(X<x)=0.9

$\large 1-e^{-x/10}=0.9\rightarrow e^{-x/10}=0.1\rightarrow x=-10ln(0.1)=23.03\;minutes$

Sydney bought a 4-pound bag of brown rice at the grocery store. The nutritional information showed that the bag

FromTheMoon [43]

Answer:

1.72973 oz/serving. Perhaps round to 1.73 oz, although there is only 1 sig fig in "4-pound bag." But the problem states "exactly."

Step-by-step explanation:

We want oz/serving, so let's convert the pounds of rice to total ounces of rice:

We are told that 16 oz = 1 pound. Make that a conversion factor: (16 oz/1 pound)

(4 pounds)*((16 oz/1 pound) = 64 ounces

We are told that 4 pounds (64 ounces) makes 37 servings. So:

(64 ounces)/(37 servings) = 1.72973 oz/serving
