20 divided from 2 plus five plus five

1 answer:

6 0

This is phrased oddly, so I'll give two responses:

They exact way you have worded it is 2/20, which is 1/10, plus 10 from the 5+5 giving you 10.1

20 divided BY 2, not FROM 2 gives you 10, plus 5 plus 5 giving you 20. Usually something is divided by something else, hence this answer, but the way you phrased it you should use the above answer

Write y= 2/3 x +7 in standard form using integers

Shalnov [3]

Answer:

The standard form of $y= \frac{2}{3} x +7$ is -2 x + 3 y = 21.

Step-by-step explanation:

Here, the given expression is : y= 2/3 x +7

The standard form of the equation is ax + by = c

Now, simplifying the above expression:

$y= \frac{2}{3} x +7 \implies y - 7 = \frac{2}{3} x$

or, $3(y-7) = 2x \implies 3y - 21 = 2x$

or, -2x + 3y = 21

Hence, the standard form of $y= \frac{2}{3} x +7$ is -2x + 3y = 21.

About 7% of the population of a large country is nervous around strangers. If two people are randomly selected, what is the prob

chubhunter [2.5K]

Answer:

Probability both are nervous around strangers = 0.0049

Probability at least one is nervous around strangers = 0.1302

Step-by-step explanation:

Let probability a person selected in the population is nervous around strangers = P

P = 7%

P = $\frac{7}{100}$

P = 0.07

Let probability a person selected in the population is not nervous around strangers = P'

P' = 1 - P

P' = 1 - 0.07

P' = 0.93

(i) probability of the first person selected is nervous around strangers = P

probability of the second person selected is nervous around strangers = P

Probability both are nervous around strangers = (P × P)

= 0.07 × 0.07

= 0.0049

(ii) Probability at least one is nervous around strangers = ( probability the first person is nervous around strangers AND the second person is not nervous around strangers ) OR ( probability the second person is nervous around strangers AND the first person is not nervous around strangers)

This implies,

Probability at least one is nervous around strangers = (P × P') or (P × P')

= (0.07 × 0.93) + (0.07 × 0.93)

= 0.0651 + 0.0651

= 0.1302
