Answer:
so the probability will be = 0.062
Standard deviation = 0.8925
Explanation:
The probability of rain = 15% = 15/100= 0.15
and the probability of no rain=q = 1-p= 1-0.15= 0.85
The number of trials = 7
so the probability will be
7C3 * ( 0.15)^3 (0.85)^4= 35* 0.003375 * 0.52200 =0.06166= 0.062
Taking this as binomial as the p and q are constant and also the trials are independent .
For a binomial distribution
Standard deviation = npq= 0.15 *0.85 *7= 0.8925
Answer:
static friction is developed between 2 surfaces in state of rest so i think answer is c.Even though the wheel is in motion, the patch of the tire in contact with the ground is stationary relative to the ground, so it is static rather than kinetic friction.
The most cited reason for the use of restraints on children that had the potential for fatality is: the prevention of of volatile or disturbing behavior that had the potential to cause injury.
<h3>What is the above research about?</h3>
The above research speaks to the use of restraints on children and seeks to highlight the fact that restraining children no matter the cause had, and continues to lead to the death of children numbered in their dozens.
The solution to this phenomena was that the sate of New York operates a service that caters to family and children and that over a space of five years, they were properly funded to train people on how to handle children.

The magnitude of the electrostatic force is 0.09 N, and the force is attractive
Explanation:
The strength of the electrostatic force acting on a charged particle is given by
![F=qE](https://tex.z-dn.net/?f=F%3DqE)
where
q is the charge
E is the magnitude of the electric field
For the charge in this problem, we have:
is the electric field
is the charge
Therefore, the force experienced by this charge is
![F=(-2.0\cdot 10^{-6})(4.5\cdot 10^4)=-0.09 N](https://tex.z-dn.net/?f=F%3D%28-2.0%5Ccdot%2010%5E%7B-6%7D%29%284.5%5Ccdot%2010%5E4%29%3D-0.09%20N)
And the negative sign means that the force is attractive: in fact, the charge is negative, while the charge that is producing the field is positive (because the electric field points outward), therefore the negative charge is attracted towards the positive charge that is generating the field.

Answer:
The magnification is a function of the lenses in the objective and the eyepiece, so the magnification of the two must be multiplied to obtain the total magnification possible. So, for example, if the objective lens was 4X and the eye piece lens was 10X, the total magnification would be 40. (4 x 10 = 40)
