Solve by elimination:<br> 4x+9y=28<br> -4x-y=-28
nikdorinn [45]

Step-by-step explanation:

4x+9y=28

-4x-y=-28

8y=0

divide both side by 8

y=0

solve for X in equation 1

4(X)-9(0)=28

4x-0=28

4x =28

divide both side by 4

4x/4=28/4

X= 7

y=0,x=7

A football quarterback enjoys practicing his long passes over 40 yards. He misses the first pass 40% of the time. When he misses
laila [671]

Answer:

Probability of missing two passes in a row is 0.08.

Step-by-step explanation:

Event E = A football player misses twice in a row.

P(E) = ?

Event X = Football player misses the first pass

P(X) = 0.4

Event Y = Football player misses just after he first miss

P(Y) = 0.2

Both the events are exclusive so the probability of occuring of these two events can be calculated by the formula:

P(E) = P(X).P(Y)

P(E) = 0.4*0.2

P(E) = 0.08

Suppose the population of a certain city is 5831 thousand. It is expected to decrease to 5204 thousand in 50 years. Find the per
SVEN [57.7K]

Answer:

The percent decrease is approximately 10.75\%

(Don't know what you are expected to round to.)

Step-by-step explanation:

Percent change can be calculated by doing:

\frac{\text{original}-\text{new}}{\text{original}}

Then you multiply the result to covert it to a percentage.

Let's use this formula:

\frac{5831 \text{thousand}-5204 \text{ thousand }}{5831 \text{thousand}}

\frac{\text{thousand}}{\text{thousand}} \cdot \frac{5831-5204}{5831}

\frac{5831-5204}{5831}

\frac{627}{5831}

0.1075 approximately

Now the answer as a percent is 10.75\% approximately.

The percent decrease is approximately 10.75\%
