Irina-Kira [14]2 years ago
8 0

The given expression is

-\frac{7}{8}\cdot\frac{7}{8}

We just have to multiply

-\frac{7\cdot7}{8\cdot8}=-\frac{49}{64}<h2>Hence, the answer is -49/64.</h2>

out of 125 children at summer camp 45 signed up for swimming 38 for arts and crafts if a child is randomly selected what is the
anzhelika [568]
P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696

Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

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}

a flomming tile has the shape of a parallelogram whose base is 24cm and height is 10 cm how many tiles are required to cove the
g100num [7]

Answer:

4 1/2 tiles are needed to cover this area

Step-by-step explanation:

Mathematically, the area of a parallelogram is the product of the base and the height

We have this as;

24 * 10 = 240 cm^2

So the area of a tile is this

The number of tiles that will cover the given area will be;

1080/240 = 4.5 tiles
