The sum of 20 and twice Vidya's height

Mathematics
1 answer:
Rus_ich [418]2 years ago
8 0

Answer:

Vidya has the height of 20/3, and the person twice Vidya's height has the height of 40/3

Step-by-step explanation:

Vidya's height and another subject, let's name him Xander, or X, has the sum of 20.

V (Vidya) + X (Xander) = 20

X = 2V

X/2 = V

Let's replace the "V" with an X!

X/2 + X = 20

Now I'm multiplying it by 2 to get rid of fractions.

X + 2X = 40

3X = 40

X = 13 1/3

Xander has the heigh of 13 1/3 or 40/3

The distribution of the amount of money spent by students on textbooks in a semester is approximately normal in shape with a mea
zheka24 [161]

Answer:

$301 - $397

Step-by-step explanation:

Using the Empirical rule

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

3)99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

From the above question,

Mean = 349 , standard deviation = 24.

Confidence interval = 95%

Using 2)95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

μ – 2σ

= 349 - 2(24)

= 349 - 48

= 301

μ + 2σ

349 + 2(24)

= 349 + 48

= 397

Therefore, according to the standard deviation rule, approximately 95% of the students spent between $301 and $397 on textbooks in a semester.

I am stuck on this question it was can you add 4+2x to get 6x
Fed [463]

Answer:

No you can't.

Step-by-step explanation:

4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)
