Answer:

a = 16. both solve and check are below.

Step-by-step explanation:

6 = a/4 + 2 is the equation given.

you have to isolate the a/4, which is by cancelling out the 2. we cancel the 2 out by subtracting 2 from both sides.

6 - 2 = a/4 + 2-2

you get the equation now:

4 = a/4

isolate a by doing the inverse operation that it is currently in. in this case, the operation they use is division. so inverse of it would be multiplication.

4*4 = a/4*4

a = 16

──────────────────

if you want to check it, you plug in a with 16 and use the PEMDAS method.

6 = 16/4 + 2

6 = 4 + 2

the equation is true, thus in a is equal to 16.

Answer:

a=16

Step-by-step explanation:

First of all you subtract both sides by 2 which makes 6-2=a/4 +2-2 which makes 4=a/4. then you multiply both sides by 4, 4x4=a/4 x 4 which makes a= 16 now you check this by putting a into the equation then going 16/4=4 then adding 2, 4+2= 6 then checking if it equals which it does

Would be amazing if you marked brainliest :)

Ooh ok these are fun. So these triangles are similar, meaning they are in proportion. In triangle LMN, line LM is 21. To find the corresponding line on the other triangle, we need to find the corresponding letters in the names. Because L and M are the first two letters, we need to use the first two letter s in the other name, so FG. Line FG is 9, so our first proportion is 9/21

Point A has coordinates (3, 4). After a translation 4 units left, a reflection across the x-axis, and a translation 2 units down

adelina 88 [10]

(-1, 2)

So the original point is (3, 4), when you move to the left or right, it changes the x value. When moving it to the right, you add the amount. When moving to the left, you subtract the amount

So after translating the point 4 units to the left, it should be (-1, 4).

Now, you have to move down. When moving up and down, you add or subtract to the y value. When moving up, you add to the amount. When moving down, you subtract the amount.

After subtracting 2, you should be at (-1, 2)

A national survey indicated that 30% of adults conduct their banking online. It also found that 40% are under the age of 50. and

Svet_ta [14]

Answer:

Step-by-step explanation:

Hello!

I'll express all the given percentages as probabilities:

Given the events:

Banking online (Bo)

Under the age of 50 (<50)

P(Bo)= 0.30

P(<50)= 0.40

P(Bo ∩ <50)= 0.25

1) What percentage of adults do not conduct their banking online?

The event "adults that do not conduct their baking online" is the complement of the event "adults that conduct their baking online" Symbolically $Bo^c$

P( $Bo^c$ )= 1 - P(Bo)= 1 - 0.30 = 0.70

2) What type of probability is 25%?

The probability P(Bo ∩ <50)= 0.25 is a joint probability, it indicates the intersection between both events.

3) Construct a contingency table showing all joint and marginal probabilities.

Check attachment.

4) What is the probability that an individual conducts banking online given that the individual is under the age of 50?

Symbolically:

P(Bo/<50)= <u> P(Bo ∩ <50) </u> = <u> 0.25 </u> = 0.625

P(<50) 0.40

I hope it helps!
