Answer:

15:32

Step-by-step explanation:

15:5+3+4×6

Using BODMAS rule

15:5+3+(4×6)

15:5+3+24

So add up

15:32

Since the two cannot be divided by the same number,we will have to leave the answer as

15:32

It costs a lumberyard $2.05 per cubic foot of lumber. If they sell the lumber back to their customers for $21.98 per cubic foot

adelina 88 [10]

Answer:

The profit per year will be $23916

Step-by-step explanation:

Cost price of 1 ft³ = $2.05

Selling price of 1 ft³ = $21.98

Profit = Selling price - cost price

profit = $21.98 - $2.05

Profit = $19.93

Profit on 1 ft³ is $19.93

If they sell 100 monthly, per year (12 months), profit will be

19.93*100*12

= $23916

It is estimated that one third of the general population has blood type A A sample of six people is selected at random. What is

Feliz [49]

Answer: 0.2195

Step-by-step explanation:

Binomial distribution formula :-

$P(x)=^nC_xp^x(1-p)^{n-x}$ , where P(x) is the probability of x successes in the n independent trials of the experiment and p is the probability of success.

Given : The probability of that the general population has blood type A = $\dfrac{1}{3}$

Sample size : n=6

Now, the probability that exactly three of them have blood type A is given by :-

$P(3)=^6C_3(\dfrac{1}{3})^3(1-\dfrac{1}{3})^{6-3}\\\\=\dfrac{6!}{3!3!}(\dfrac{1}{3})^3(\dfrac{2}{3})^{3}\\\\=0.219478737997\approx0.2195$

Therefore, the probability that exactly three of them have blood type A = 0.2195

Answer:

∠A = 6x + 4

Step-by-step explanation:

Hello There!

We are given the exterior angle ∠ACD and an interior angle ∠B

If you didn't know this is the rule for exterior angles of a triangle:

An exterior angle is equal to the sum of its opposite interior angles

so ∠ACD = ∠A + ∠B ( ∠A and ∠B being the opposite interior angles)

So with the information that we are given we plug them into their corresponding angle

then we would have

8x+5 = ∠A + 2x + 1

now we solve for A

Well how do we solve for A?

Well we have to isolate the variable

To do so we want to get rid of 2x + 1

We do that by subtract each side by 2x and 1

8x + 5 - (2x + 1 ) = 6x + 4

we're left with

∠A = 6x + 4
