Sarah chances would be 8 out of 14 and reduced to lowest term will be 4/7. The chances of selecting both as oranges would be the double (4/7) so you would have to do this
4/7 * 4/7 = 16/49

Determine the values of the parameter s for which the system has a unique​ solution, and describe the solution. sx 1 minus 2 sx
JulijaS [17]

Note: The equations written in this questions are not appropriately expressed, however, i will work with hypothetical equations that will enable you to solve any problems of this kind.

Answer:

For the system of equations to be unique, s can take all values except 2 and -2

Step-by-step explanation:

2sx_{1} + 4x_{2} = -3\\2x_{1} + sx_{2} = 4

\left[\begin{array}{ccc}2s&4\\2&s\end{array}\right] \left[\begin{array}{ccc}x_{1} \\x_{2} \end{array}\right] = \left[\begin{array}{ccc}-3 \\6 \end{array}\right]

For the system to have a unique solution, \begin{vmatrix} 2s & 4 \\ 2 & s \end{vmatrix} \neq 0

2s^{2} -8 \neq 0\\2s^{2}\neq 8\\s^{2}\neq 4\\s \neq 2 or -2

A ball is dropped from a height of 8 feet. If every time it bounces, it bounces 60% of its previous height, what is the total di
vladimir1956 [14]

Answer:

<h3>20feet</h3>

Step-by-step explanation:

Initial height of the ball = 8feet

If it bounces 60% of its previous height, its new height will be;

60% of 8

= 60/100 * 8

= 480/100

= 4.8 ft

If it bounces 60% of its current distance, new height will be expressed as;

60% of 4.8

= 0.6 * 4.8

= 2.88

The height of the ball will keep reducing and form a geometric progression of the form 8, 4.8, 2.88...

In order to get the total distance traveled by the ball, we need to calculate the sum to infinity of the sequence;

S∞ = a/1-r where;

a is the first term = 8

r is the common ratio

r = \frac{4.8}{8} = \frac{2.88}{4.8}\\r =  0.6

Substitute into the formula;

S∞ = a/1-r

S∞ = 8/1-0.6

S∞ = 8/0.4

S∞ = 20feet

Hence the total distance traveled by the ball is 20feet
