M•8=24
Multiplication will become division when it changes side
m=24÷8
=A

k+26=61
Addition will become subtraction when it changes side
k=61-26
=B

Hello there, and thank you for posting your question here on brainly.

Okay, so the first one, m * 8 = 24, you can divide 24 by 8 to solve what m is.

24 / 8 = 3.

3 * 8 = 24

So now we know that answer choice A. is correct for the first one.

Next one, k + 26 = 61

We can subtract 61 by 26 to solve this one out.

61 - 26 = 35

35 + 26 = 61

With that, we know it is B. k = 61 - 26

Now the third one, 17k = 34

We can divide 34 by 17 to solve.

34 / 17 = 2

17 * 2 = 34

With that, the answer is B. k = 2

Now the fourth one, t/3 = 15

We can multiply 3 by 15 to solve for t.

3 * 15 = 45

45 / 3 = 15

With this, we know the answer is D. 45

Now the last one, the fifth one. p + 6 = 18

Subtract the numbers.

18 - 6 = 12

12 + 6 = 18

The answer is B. 12.

Hope this helped!! ☺♥

It's an overcast day in Hayward and you're waiting for AC Transit 97 Bus Line to show up. Your weather app says there's a 30% ch

melomori [17]

Answer:

a

$P(r n L) = 0.12$

b

$P(L) = 0.225$

c

$P(\= r | L) = 0.4667$

Step-by-step explanation:

The chance that it will rain is $P(r ) = 0.30$

The chance that it does not rain is $P(\= r ) = 1 - P(r )$

$P(\= r ) = 1 -0.30$

$P(\= r ) = 0.70$

The probability that the bus run late if it rains is $P(L | r) = 0.4$

The probability that the bus run late if it does not rain is $P(L | \= r) = 0.15$

Generally the probability that it will rain and the bus will be late is mathematically represented as

$P(r n L) = P(L | r) * P(r)$

=> $P(r n L) = 0.4 * 0.30$

=> $P(r n L) = 0.12$

Generally the probability that the bus will be late is mathematically represented as

$P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)$

=> $P(L) = 0.30 * 0.4 +0.15*0.70$

=> $P(L) = 0.225$

Generally given that the bus ran late, the probability that the bus it was not raining is mathematically represented as

$P(\= r | L) = 1- P(r | L )$

Here $P(r | L ) = \frac{P(r n L)}{P(L)}$

=> $P(r | L ) = \frac{0.12}{0.225}$

=> $P(r | L ) = 0.533$

So

$P(\= r | L) = 1- 0.533$

=> $P(\= r | L) = 0.467$

Hey can you please help

AfilCa [17]

Answer:

Measure of major arc BDC = 260.5° Option A

Step-by-step explanation:

Given that, measure of central angle ∠BAE = 80.5°

Firstly we will find the measure of arc BE .

The measure of arc BE is same as the measure of its central angle.

So, measure of minor BE arc = 80.5°

measure of arc EDC = 180° because of half circle

So,

measure of major arc BDC = 180° + 80.5° = 260.5° option A

That's the final answer.
