Kipish [7]

Answer:

<em>The probability of scoring two goals in both times is</em><em> 0.137 or 13.7%</em>

Step-by-step explanation:

Statistics show that a certain soccer player has a 63% chance of missing the goal each time he shoots.

So $P(A)=0.63$

Hence, the probability of getting success in his shoots will be,

$P(A^c)=1-P(A)=1-0.63=0.37$

The probability of scoring two goals in both times is,

$=P(A^c)\cdot P(A^c)$

$=0.37\times 0.37$

$=0.137$

$=13.7\%$

How to put -3x(4-6x) in distributive property

Rashid [163]

Answer:

-12x+18x²

Step-by-step explanation:

Given: $-3x(4-6x)$

Distributive property of multiplication under which a number is multiplied by the sum of two number, the first number can be distributed to both of those number.

∴ $-3x(4-6x)$

solving it by using distributive property

= $(-3x\times 4)-(-3x\times 6x)$

= $-(12x) + 18x^{2}$

Opening parenthesis

= $-12x+18x^{2}$

Hence, -12x+18 $x^{2}$ is the result after using distributive property.
