Part A)
 The coin landed on heads 9 times out of 30 flips, so the experimental probability is 9/30, which reduces to 3/10 probability.

Part B)
 Theoretically a coin has a 1/2 probability of landing on heads each flip

HACTEHA [7]

Answer:

The subscription began about 10 days before the 15th of the month.

Step-by-step explanation:

The correct option is:

The subscription began about 10 days before the 15th of the month.

The reason for being charged $60 instead of $45 which is the monthly rate is that they started the subscription prior the the cycle date of the bill period. Due to the change in the cycle date, the customer is getting a prorated charge for the days that had service prior to the date of the bill and current cycle starting

X=3y+10 x=-8y-12<br><br> can u guys help me find the steps to solve this equations
Natalija [7]

Answer:

x=4, y=-2

Step-by-step explanation:

x = 3y + 10 \\ x =  - 8y -12\\ now \\ 3y  + 10 =  - 8y - 12 \\ 3y + 8y =  - 12 - 10 \\ 11y =  - 22 \\ y =  \frac{ - 22}{11}  \\ y =  - 2 \\ again \: putting \: the \: value \:of \: y \\ x = 3y + 10 \\ x = 3( - 2) + 10 \\ x =  - 6 + 10 \\ x = 4

murzikaleks [220]

The probability that at least one child among the 3 will get influenza is 0.07.

<h3>Define probability.</h3>

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

Given,

3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine

Probability that at least one child among the 3 will get influenza

P(at least one child among the 3 will get influenza)

=  1 - P(no one have influenza)

= 1 - (1- 0.0.378)(1-0.017)²

= 1 - 0.93

= 0.07

The probability that at least one child among the 3 will get influenza is 0.07.
