In the equation 6-A/4=-3, what would A be?

ElenaW [278]

I don't know. Let's solve it together. Then we'll both know what 'A' is,
and PLUS, you'll know how to find it.

6 - A/4 = -3

We want to get 'A' all by itself on one side of the equation,
and everything else on the other side.

Subtract 6 from each side: - A/4 = -9

Multiply each side by 4 : -A = -36

Multiply each side by -1 :  A = 36

Did you follow that ?

Answer:

Siobhan is making a total of $9.12 per hour.

Step-by-step explanation:

James makes $8 an hour.

Priya makes 20% more, so:

8.00 + 20% = $9.60

Siobhan makes 5% less, so:

9.60 - 5% = $9.12

Thus, the answer is $9.12.

For each day in New England, the probability that it is mostly cloudy is 0.10 . Cindi is planning to go leaf watching, and her f

Answer:

0,37

Step-by-step explanation:

It will be easier if we noun the events.

A= Cindi's friend comes to England.

B= New England is mostly cloudly.

We are searching the probability of just A doesn´t happen or just A happens but not B.

The probability of A doesn´t happen is one minus the probability of A:

$=(A^{|} )=1-P(A)=1-0.7=0.3$

The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:

$P(A \cap B)= P(A)P(B)=0.1*0.7=0.07$

The probability of A doesn´t happen or A and B happen is:

$P(A^{|} \cup (A \cap B))= P(A^{|} )+P (A \cap B)-P(A^{|} \cap A\cap B)=0.3+0.07-0=0.37$

Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.

$P(A^{|} \cup (A \cap B))-P(A^{|} \cap A\cap B)=0.37-0=0.38$

Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37
