Answer:

The Radius is 6.5 cm.

Step-by-step explanation:

We know that the diameter of a circle is a line that begins on one point of a circle and ends on the opposite side. We also know that the radius is a point on the circle that starts from that point and ends at the center. Therefore, the radius would be half the diameter.

$13/2 = 6.5$

Hope this helped :D!

guajiro [1.7K]

Answer: 0.27

Step-by-step explanation:

Given that :

Probability of being a strike ; p(strike) = 0.3

Note : the probability of each pitch Beau is independent :

Probability that next three will be a strike :

p(strike) * p(strike) * p(strike)

= 0.3 * 0.3 * 0.3

= 0.27

Problem 1 Answer: $x=10$

<u>Simplify both sides of the equation</u>

<u></u> $(2)(x)+(2)(-3)=14(Distribute)$ <u></u>

<u></u> $2x+-6=14$ <u></u>

<u></u> $2x-6=14$ <u></u>

<u></u>

<u>Add 6 to both sides</u>

$2x-6+6=14+6$

$2x=20$

<u></u>

<u>Divide both sides by 2</u>

<u></u> $2x/2=20/2$ <u></u>

<u></u> $x=10$ <u></u>

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

Problem 2 Answer: $x=-7$

<u></u>

<u>Simplify both sides of the equation</u>

<u></u> $(-5)(x)+(-5)(-1)=40(Distribute)$ <u></u>

<u></u> $-5x+5=40$ <u></u>

<u></u>

<u>Subtract 5 from both sides</u>

<u></u> $-5x+5-5=40-5$ <u></u>

<u></u> $-5x=35$ <u></u>

<u></u>

<u>Divide both sides by -5</u>

<u></u> $-5x/5=35/-5$ <u></u>

<u></u> $x=-7$ <u></u>

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

Problem 3 Answer: $x=-8$

<u></u>

<u>Simplify both sides of the equation</u>

<u></u> $(12)(x)+(12)(10)=24(Distribute)$ <u></u>

<u></u> $12x+120=24$ <u></u>

<u></u>

<u>Subtract 120 from both sides</u>

<u></u> $12x+120-120=24-120$ <u></u>

<u></u> $12x=-96$ <u></u>

<u></u>

<u>Divide both sides by 12</u>

<u></u> $12x/12=-96/12$ <u></u>

<u></u> $x=-8$ <u></u>

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

Problem 4 Answer: $x=-1/2$

<u></u>

<u>Move all terms to the left:</u>

<u></u> $2(x+6)-(11)=0$ <u></u>

<u></u>

<u>Multiply parentheses</u>

<u></u> $2x+12-11=0$ <u></u>

<u></u>

<u>Add all the numbers together, and all the variables</u>

<u></u> $2x+1=0$ <u></u>

<u></u>

<u>Move all terms containing x to the left, all other terms to the right</u>

<u></u> $2x=-1\\x=-1/2$ <u></u>

Plz help me ASAP I will give Brainliest if right. What is the probability that he gets a number less than 4 or A multiple of 4?

mezya [45]

Answer:

5/8

Step-by-step explanation:

The sectors are labeled 1,2,3,4,5,6,7,8

Numbers less than 4: 1,2,3

Multiples of 4: 4,8

We are looking for 1,2,3,4,8 = 5 choices

P (1,2,3,4,8) = Number of choices/ total

= 5/8
