14 times

Add up all the numbers in the table and you get 50. If every 50 spins it lands on 1 seven times. 50x2=100 so 7x2=14

Answer:

14

Step-by-step explanation:

We can see that the spinner is spun 50 times if we add all the "times spun" up.

7 + 8 + 7 + 8 + 11 + 9 = 50

So if we multiply this by 2, we should get the theoretical probability that 1 will be spun if the spinner was spun 100 times.

1 was spun 7 times when we spun the spinner 50 times, so we can predict that 1 will be spun 14 times if we spin the spinner 100 times.

Find the maximum walking speed of a coyote with legs 0.46 m long. How much faster can a giraffe walk than a coyote?
AfilCa [17]

Answer:

7.03 ft/s

Step-by-step explanation:

To obtain speed using the model :

Speed = sqrt(gL)

L = Length of leg, g = acceleration due to gravity

Length of leg of a giraffe = 6.03

g = 9.8 m/s or 32 ft/s²

Speed of giraffe in ft/s = sqrt(32 * 6.03) = 13.89 ft/ s

Speed of coyote ; L = 0.46 m

L in feets = 0.46 * 3.23 = 1.4858 feets

s = sqrt(1.4858 * 32) = 6.895 ft/s = 6.86 ft/s

Difference in speed :

13.89 - 6.86 = 7.03 ft/s

Giraffe has 7.03ft/s more speed Than a coyote

How do you implicitly differentiate: sqrt(xy)=x^2y+1
Furkat [3]
Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression 
<span>sqrt(xy)=x^2y+1 is

sqrt x * 0.5 y ^-0.5 dy + </span>sqrt y<span> * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx 
dy (x^2 - 0.5 (</span>x/y) ^0.5) = dx (2xy  - 0.5 (y<span>/x)^0.5) 
dy/dx = </span>(2xy  - 0.5 (y/x)^0.5) / (x^2 - 0.5 (<span>x/y) ^0.5)</span>

Hey, Its the same person. This is Algebra 2. Please Help!
suter [353]

Answer:

first option

Step-by-step explanation:

Given

f(x) = \frac{2x^2+5x-12}{x+4} ← factorise the numerator

     = \frac{(x + 4)(2x-3)}{x+4} ← cancel (x + 4) on numerator/ denominator

     = 2x - 3

Cancelling (x + 4) creates a discontinuity ( a hole ) at x + 4 = 0, that is

x = - 4

Substitute x = - 4 into the simplified f(x) for y- coordinate

f(- 4) = 2(- 4) - 3 = - 8 - 3 = - 11

The discontinuity occurs at (- 4, - 11 )

To obtain the zero let f(x) = 0, that is

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

There is a zero at ( \frac{3}{2}, 0 )

Thus

discontinuity at (- 4, - 11 ), zero at ( \frac{3}{2}, 0 )
