Answer:

$1 : ~2.1666667 ounce package

<em>~</em><em> </em><em>means</em><em> </em><em>about</em><em>;</em><em> </em><em>estimation</em>

How we solve this

$6 (÷6) -> $1

13 (÷6) -> 2.16666667

We divide the exact number by the number of the price to get the proportion of each ratio.

Add an intersection the red light times normally distributed by the mean of three minutes and a standard deviation of .25 minute
Soloha48 [4]

95% of red lights last between 2.5 and 3.5 minutes.

<u>Step-by-step explanation:</u>

In this case,

  • The mean M is 3 and
  • The standard deviation SD is given as 0.25

Assume the bell shaped graph of normal distribution,

The center of the graph is mean which is 3 minutes.

We move one space to the right side of mean ⇒ M + SD

⇒ 3+0.25 = 3.25 minutes.

Again we move one more space to the right of mean ⇒ M + 2SD

⇒ 3 + (0.25×2) = 3.5 minutes.

Similarly,

Move one space to the left side of mean ⇒ M - SD

⇒ 3-0.25 = 2.75 minutes.

Again we move one more space to the left of mean ⇒ M - 2SD

⇒ 3 - (0.25×2) =2.5 minutes.

The questions asks to approximately what percent of red lights last between 2.5 and 3.5 minutes.

Notice 2.5 and 3.5 fall within 2 standard deviations, and that 95% of the data is within 2 standard deviations. (Refer to bell-shaped graph)

Therefore, the percent of  red lights that last between 2.5 and 3.5 minutes is 95%

HELP ASAP CAUSE ITS DUE TODAY AND I DIDN'T FINISH IT!!!!!! <br><br><br>im sorry-!
Serjik [45]

Answer: 1 = 8 cups because 2 x 4 = 8.

2. 35... 7 x 10 = 70, 70 / 2 = 35

      1  

3.  20.53 + 1.55 + 0.02..        line up decimals!

<u> +    1.55</u>

   22.08

4. Mean is average.

so add up all the numbers and divide by the amount of numbers you added

18+9 = 27, 27 + 15 = 42, 42 + 11 = 53, 53 + 13 = 66, 66 + 15 = 81.

81 divided by 6 = 13.5 or 13 1/2.

5. c = 5b

b=55

c = 5 x 55

5 x 55 = 275.

c = 275.

<u>NEXT PAGE</u>

<u></u>

1. 48, 6 x 8 = 48.

2. 6, 4 x 3 = 12, 12 / 2 = 6

       1

3. 9. 12 + 5.78 + 6.01

   5.78

<u>+  6.01</u>

  20.91

4. 36 + 42 + 66 + 54 + 23 = 221, 221 / 5 = 44.2 or 44 1/5

5. t = 20c         c = 21

t = 20 x 21 = 420

t = 420.

The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
