Based on these results, which is the most reasonable prediction of the
number of times chocolate is selected if
only 81 students are surveyed?

A 10
B 20
C 50
D 15

Answer:

17.6 miles.

Step-by-step explanation:

Use Pythagoreans Theorem to find c.

a^2+b^2=c^2

49 + 9 = c^2

58 =c^2

√58=c

7.6=c

Now add all of your sides together to find the perimeter.

7 + 3 + 7.6 = 17.6 miles.

The perimeter of the triangle is 17.6 units.

The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.

Using the Pythagorean theorem, we can find the length of the hypotenuse c:

c² = a² + b²

c² = 7² + 3²

c² = 58

c = √58 ≈ 7.6 miles

The perimeter is the sum of the three sides:

Perimeter = a + b + c

Perimeter = 7 + 3 + 7.6

Perimeter ≈ 17.6 miles

The solution if h(x) = g(x) is ±1

Given the following functions

h(x)=1+2x/x

g(x)=2+x

The solution of the function occur at h(x) = g(x)

If h(x) =  g(x), then;

1+2x/x  = 2 + x

Cross multiply

1+2x = x(2+x)

1 + 2x = 2x + x^2

Equate the resulting expression to zero to have;

x^2 = 1

x = ±1

Hence the solution if h(x) = g(x) is ±1

Step-by-step explanation:

Answer:

x = 9cm

using sine rule

a/sine(A) = b/sine(B)

a= x; A= 64° ( alternating angles)

b= 10 cm ; B = 90°

x/sine(64) = 10/sine(90)

x= {10 × sin(64)}/ sin 90

x = 9cm

The probability of drawing a purple marble is 3/10

Answer:

4 or -4

Step-by-step explanation:

Y is directly proportional to x^2 means there is a constant, k, such that y=kx^2.

We are given y=8 when x=2. This information will allow us to find k in the equation y=kx^2.

8=k(2)^2

8=k(4)

This implies k=2 since 2(4)=8.

So the equation for any pair (x,y) is y=2x^2.

We want to find x when y=32.

32=2x^2

32/2=2x^2/2

16=x^2

This implies x=4 or -4.

The amount she will withdraw is $2,419.44. (option d)

The interest earned in the account is the difference between the amount invested and the future value of the investment.

Interest earned = future value - amount invested

The formula for calculating future value:

FV = P (1 + r)^nm

Where:

FV = 1000 x (1 + 0.0375)^(6 x 4)

= 1000 x (1.0375^24) = $2,419.44

Interest earned = $2,419.44 - $1000 = $1,419.44

Answer:

The value of x is -5 and y is 1

Step-by-step explanation:

Here,

y = -3x - 14

-2x - y = 9

Substitution Method

y = -3x - 14 ...(1)

-2x - y = 9 ...(2)

Now, substitute the value of y = -3x - 14 in equation (2) we get,

-2x - y = 9

-2x - (-3x - 14) = 9

-2x + 3x + 14 = 9

x = 9 - 14

x = -5

Now, put the value of x in equation (1) we get,

y = -3x - 14

y = -3(-5) - 14

y = 15 - 14

y = 1

Thus, The value of x is -5 and y is 1

y = -3x - 14

1 = -3(-5) - 14

1 = 15 - 14

1 = 1

-2x - y = 9

-2(-5) - 1 = 9

10 - 1 = 9

9 = 9

Hence, L.H.S = R.H.S

The diver is at a distance of 380 feets below sea level

Step-by-step explanation:

An absolute value statement which is equivalent to being at an elevation of - 380 feets is to relate the position to being above or below sea level.

Elevation below sea level are represented as negative while elevations above take positive values.

The sea level represents a midpoint or zero point for representibg distances.

Hence, at - 380 feets, the diver is at a distance of 380 feets measured for the sea level below.
