Answer:

13.69%.

Step-by-step explanation:

The probability he scores in 1 shot = 1 - 0.63 = 0.37.

The probability that he scores twice in 2 shots = 0.37 * 0.37

= 0.1369

= 13.69%.

The probabilities are multiplied because the 2 events are independent.

Solve 5x − 6y = −38 <br> 3x + 4y = 0
Leto [7]

Answer:

x = -76 , y = 57

Step-by-step explanation:

5x - 6y = -38

3x + 4y = 0

------------------

use 4 to multiply equation 1

5x(4) - 6y(4) = - 38(4)

20x -24y = -152

----------------------

use 6 to multiply equation 2

3x(6) + 4y(6) = 0(6)

18x + 24y = 0

------------------------

20x - 24y = -152

18x + 24y = 0

----------------------

2x = -152

----------------

divide 2 by both sides

x = -76

--------------------

to find y, slot in the of x to either equation 1 or 2

--------------------------------

equation 2

3x + 4y = 0

3(-76) + 4y = 0

------------------------

-228 + 4y = 0

4y = 228 - 0

4y = 228

---------------------

divide both sides by 4

----------------------------------

y = 57

for this type of question, you can use

  1. substitution method
  2. elimination method
  3. graphical method

i used substitution method

hope it helps

Mr. Hynes waters each tomato plant with a quart of water every day. How many gallons of water does he use to water 6 tomato plan
olya-2409 [2.1K]

Answer:

  • There are six tomato plants.
  • June has thirty days.
  • Each tomato plant requires one quart of water for thirty days.
  • 4 quarts equals one gallon of water.
  • We have to convert the number of quarts into the number of gallons at the end.

Step-by-step explanation:

6 tomato plants mean six quarts of water.

Six quarts of water to be used for thirty days.

6 x 30 = 180 quarts of water

Now we have to convert the number of quarts into amounts of gallons.

We divide 180 by 4 because four quarts equal one gallon of water.

ANSWER: 45 gallons of water
