Answer:

The answer is:

$\frac{2a}{2b} = 5$

Step-by-step explanation:

Substitute the values of a and b into the equation

$a = 10&b = 2 \\ \\ \frac{2a}{2b} = 5 \\ \\so \frac{2(10)}{2(2)} = 5$

$\frac{20}{4} = 5 \\ \\ 5 = 5$

in 2005, the total waste generated in a certain country was 3.474x10^9 pounds. also in 2005, the countrys population was 1.23x10

Serggg [28]

Answer:

2824

Step-by-step explanation:

Take the number of pounds and divide by the number of people:

3.474×10⁹ / 1.23×10⁶

Divide the coefficients and subtract the exponents:

(3.474 / 1.23) × 10⁹⁻⁶

2.824×10³

So the country produced about 2,824 pounds of garbage per person in 2005.

Would an experience downhill skier want the slope of the hill to be 1/10 or 9/10? Why?<br><br>

kolezko [41]

Answer:

9/10

Step-by-step explanation:

step 1

Compare the slopes

$1/10=0.10$

$9/10=0.9$

$0.9 > 0.10$

therefore

An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.

Admission to a baseball game is $3.00 for general admission and $5.50 for reserved seats. The receipts were $3277.50 for 845 pai

a_sh-v [17]

Answer:

548, 297

Step-by-step explanation:

We can set this up as a system of equations. The first equation is for how many tickets were sold, which is x+y=845. The second equation is for the cost of the tickets, which is 3x+5.5y=3277.50. The best method for this problem (other than graphing) is elimination. First, we need to multiply one equation to get the opposite of one of the variables. The easiest one to do for this problem is x. The opposite of 3 is -3, so we have to multiply ALL of the first equation by -3. If you do this, then you get -3x-3y=-2535. Now, combine the equations:

3x + 5.5y = 3277.50

-3x -3y = -2535

________________

0x+2.5y=742.5

Now, isolate y by dividing both sides by 2.5. If you do this, you get y=297. Now, plug this in for the y in the first equation. Isolate x.

x+297=845

-297 -297

__________

0 548

x=548

Hope this helps!

Greeley [361]

Answer:

The probability mass function is

$F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }$

Step-by-step explanation:

From the question we are told that

The maximum transmission time is $n = 8$

Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p

Generally the probability mass function is mathematically represented as

$F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }$

Here x can take values x = 0 , 1 , 2 , 3 , ... , 7
