What is the difference between 28.935 and 13.011 , to the nearest integer?

The number of days each licensed driver in Marion County uses a commuter rail line annually is normally distributed with mean 66

alexira [117]

Answer:

31.5 days

Step-by-step explanation:

We.solve using z score formula

z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

The 5th percentile z score = -1.645

Mean = 66

Standard deviation = 21

Hence:

-1.645 = x - 66/21

-1.645 × 21 = x - 66

-34.545 = x - 66

-34.545 + 66 = x

x = 31.455 days

Approximately to the nearest round integer

= 31.5 days

Therefore, driver use a commuter rail line 31.5 days annually to be in the top 5% of rail users

lauren graphed the relationship between how many days had passed since she planted a cactus and it’s height (in centimeters)

Hello! Remember you have to write complete questions in order to get exact and good answers. However, I found a similar question on the internet which is attached below and want to explain it to you. Here we know that the graph is a line that passes through the points $(30,10) \ and \ (50,20)$ So the slope is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ \\ (x_{1},y_{1})=(30,10) \\ \\ (x_{2},y_{2})=(50,20) \\ \\ \\ m=\frac{20-10}{50-30}=\frac{1}{2}$

<em>From the slope we know that the plant grows 1 cm every two days.</em>

When an apple is dropped from a tower 256 feet high, the function h(t) =-167 +256 models the height of the

DerKrebs [107]

Answer:

around 1.5 sec

Step-by-step explanation:

basically you wanna figure out at what time is the height=0

since h(t) represents height, set it to 0 then solve for t

i believe you might have forgotten the t in the equation so i assumed it was -167t

0=-167t+256

-256=-167t

t=1.53293413174

around 1.5 seconds after it was dropped

alternatively, you could plug the equation into desmos, replacing h(t) with y and t with x and find the x intercept

Which of the three following graphs display the same data?

Zepler [3.9K]

Answer:

B. I and III

Step-by-step explanation:

I and III both have the same data:

March, 73

April 74

May 78

June 84

July 75

II has different data

March 71

April 72

May 85

June 90

July 60

Since I and III have the exact same data, choice B is the best answer

Hope this helps! :)
