stepladder [879]3 years ago
5 0

Answer:

6. is H

7. is B

Explanation:

the communitive property states that if: a+b=c, then b+a=c

if each ballon costs 2 dollars, that would b 2x or $2 (aka the 2) for 1 balloon (aka the x) and since he has a 10$ off coupon, you have to subtract 10$ so y=2x-10

A curve passes through the point (0, 5) and has the property that the slope of the curve at every point P is twice the y-coordin
Anit [1.1K]

Answer:

y=5e^{2x}

Step-by-step explanation:

Let (x,y) represents a point P on the curve,

So, the slope of the curve at point P = \frac{dy}{dx}

According to the question,

\frac{dy}{dx}=2y

\frac{1}{y}dy=2dx

Integrating both sides,

\int \frac{dy}{y}=2dx

ln y=2x+ln C

ln y-ln C = 2x

ln(\frac{y}{C})=2x

\frac{y}{C}=e^{2x}

\implies y=Ce^{2x}

Since, the curve is passing through the point (0, 5),

5=Ce^{0}\implies C=5

Hence, the required equation of the curve is,

y=5e^{2x}

Normal Distribution
MariettaO [177]

Answer:

No

Step-by-step explanation:

<u>Explanation</u>:-

  • The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ

        So The first statement is not true because symmetrical about the line        x = μ not 'm'

  • Area under normal curve represents the total population

so the total area under the curve is 100 or one so  The second statement is true

  • The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.
  • 95 percentage within two standard deviations
  • 99.7 percentage of the data are within three standard deviations of the mean.
  • 68 percentage of the data are within one standard deviation

All above points are true so In given data the third statement is not true

95 percentage within two standard deviations not one

  • The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.
  • All data sets are normally distributed its depend on given data
