Answer:

acceleration of the golf ball will be faster. ( A )

Step-by-step explanation:

if you DROP a bowling ball vs a golf ball, the bowling ball will drop faster cause it’s heavier. but if you push a golf ball vs a bowling ball with the same force, the golf ball will be faster because it’s lighter. pushing a bowling ball with a lot of force will move it a certain amount, but moving a golf ball with that same force will go way past the bowling ball just cause it’s lighter.

A particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls invol

Phoenix [80]

Answer:

0.1091 or 10.91%

Step-by-step explanation:

We have been given that a particular telephone number is used to receive both voice calls and fax messages. suppose that 20% of the incoming calls involve fax messages and consider a sample of 20 calls. We are asked to find the probability that exactly 6 of the calls involve a fax message.

We will use Bernoulli's trials to solve our given problem.

$P(X=x)=^nC_x\cdot P^x(1-P)^{n-x}$

$P(X=6)=^{20}C_6\cdot (0.20)^6(1-0.20)^{20-6}$

$P(X=6)=\frac{20!}{6!(20-6)!}\cdot (0.20)^6(0.80)^{14}$

$P(X=6)=\frac{20!}{6!(14)!}\cdot (0.000064)(0.04398046511104)$

$P(X=6)=38760\cdot (0.000064)(0.04398046511104)$

$P(X=6)=0.1090997009730$

$P(X=6)\approx 0.1091\\$

Therefore, the probability that exactly 6 of the calls involve a fax message would be approximately 0.1091 or 10.91%.

Reduce 7y + 2y 2 - 7 by 3 - 4y.

NARA [144]

Answer:

D. $2y^2+11y-10$ .

Step-by-step explanation:

Given:

We need to reduce $7y+2y^2-7$ by $3-4y$

Solution:

To reduce the equation means we need to subtract the one equation from other.

First we will arrange the equation n proper format we get;

$2y^2+7y-7$ ⇒ equation 1

Also Arranging other equation we get;

$-4y+3$ ⇒ equation 2

Now we will subtract equation 2 from equation 1 we get;

$(2y^2+7y-7)-(-4y+3)$

Now Applying distributive property for the sign we get;

$2y^2+7y-7+4y-3$

Now Arranging the like terms we get;

$2y2+7y-+4y-7-3\\\\2y^2+11y-10$

Hence the reduce form of the given equation is $2y^2+11y-10$ .
