Answer:

  -2

Step-by-step explanation:

Between the first two steps we see ...

  15(x-\boxed{^})=25\\\\15x+30=25

Applying the distributive property to the first equation and comparing to the second, we see that ...

  -15\boxed{^}=30\\\\\boxed{^}=\dfrac{30}{-15}=-2

The number in the box should be -2.

Numbered disks are placed in a box and one disk is selected at random. If there are 6 red disks numbered 1 through 6, and 2 yell
Tatiana [17]

Answer:

\frac{3}{4}

Step-by-step explanation:

Total number of red disk=6

Total number  of yellow disk=2

Total disk=6+2=8

Odd number=1,3,5,7=4

Odd number on red disk=1,3,5=3

Probability,P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}

Using the formula

The probability of getting odd number disk=\frac{4}{8}=\frac{1}{2}

The probability of getting odd numbered  red disk=\frac{3}{8}

The probability of selecting a red disk,given that an odd numbered disk is selected=\frac{\frac{3}{8}}{\frac{1}{2}}=\frac{3}{8}\times 2=\frac{3}{4}

Using conditional probability

P(A/B)=\frac{P(A\cap B)}{P(B)}

Step-by-step explanation:

The equation V=-32t+256 and the graph below describe the velocity V in feet per second of a ball <em>t</em> seconds after it is shot into the air.

To find the balls velocity after seven seconds, substitute t = 7 into the function expression:

V(7)=-32\cdot 7+256\\ \\=-224+256\\ \\=32\ ft/sec
