There is about a 29.62% chance of you drawing a number between 4 and 9 or 5,6,7,8.

For the units positions of all numbers we have:
$z+7+5=4 \\ z+12=4$
From this we can conclude that total sum of these three numbers is 14. Number 1 we carry to next step. So we have:
$z+12=14 \\ z=2$

For the tens positions of all numbers we have:
$4+2+x+1=1 \\ 7+x=1$
The extra number 1 on left side comes from the carry from last step. Similar to ones position we know that total sum is 11.
$7+x=11 \\ x=4$

Now we insert x and z to find out y:
$42+27+45=y14 \\ 114=y14 \\ y=1$

Now we need to find out the product of these three numbers:
$x*y*z=4*1*2=8$

Answer:

<em>M(13)=14.3 gram</em>

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

$C(t)=C_o\cdot(1-r)^t$

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.

The equation of the model is:

$M(t)=M_o\cdot(1-r)^t$

$M(t)=970\cdot(1-0.277)^t$

Operating:

$M(t)=970\cdot 0.723^t$

After t=13 minutes the remaining mass is:

$M(13)=970\cdot 0.723^{13}$

Calculating:

M(13)=14.3 gram

Enter the value of y that makes the given equatlon true.<br> 15y +3= 6

Lunna [17]

Answer:

y = 1/5 or y = 0.2

Step-by-step explanation:

$15y +3= 6\\15y+3-3=6-3\leftarrow \text {Subtraction Property of Equality} \\15y=3\\\\\frac{15y}{15} =\frac{3}{15} \leftarrow \text {Divsion Property of Equality}\\$

$y=\frac{3}{15}\\\frac{3/3}{15/3} = \frac{1}{5} \leftarrow \text {Simplifying the Answer}\\\boxed{y=\frac{1}{5}}$
