William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
What is the probability that one of the events William worked on last year, selected at random, was an anniversary party?
Write your answer as a fraction or whole number.
Answers
Answer:
hello
Step-by-step explanation:
The required probability that William worked on last year was an anniversary party is 1/ 36.
As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36
Thus, the required probability that William worked last year is 1/ 36.

0.5% of w is 12 is what they are asking
0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is
\(12 = 0.005 \times w\)
Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite
\(w = \frac{12}{0.005} = 2400\)

Geraldo is going to buy a new fishing pole and bait before he meets up with his friends this afternoon. The fishing pole cost $15. The bait cost $2.75 per pound and is only sold in full pounds (you can't get half a pound.) If Geraldo has $30, how much bait can he buy?
Answers
Answer:
5 pounds
Step-by-step explanation:
Answer:
5 pounds
Step-by-step explanation:
We can use a inequality to answer this question: it will be
--- 2.75b + 15 < 30 (let b equal the bait)
subtract 15 on both sides
---- 2.75b < 15
divide 2.75 on both sides
---- b = 5.4.... (rounded)
Since you can't buy some of a pound, he can Geraldo can only buy 5 pounds of bait. Hope this helps.

a. The measure of ∠ ABD is 6.2 times greater than the measure of ∠ CBD. Find the measure of ∠ CBD.
b. ∠ FBE and ∠ EBD are congruent. Find the measure of ∠ FBE
Answers
Answer:
awnser B and fbe is 55
Step-by-step explanation:
the entire picture is 180 so cut in half there for 90 ok abfe is 90 so bigger section is always 55 and smaller is 35 ok
If the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.
Given that the measure of ∠ ABD is 6.2 times greater than the measure of ∠ CBD and ∠ FBE and ∠ EBD are congruent.
We are required to find the measure of ∠ CBD and ∠ FBE.
∠ABD=6.2*∠CBD--------1
∠ABD+∠CBD=180°
6.2 ∠CBD+∠CBD=180 (From equation 1)
7.2 ∠CBD=180
∠CBD=180/7.2
∠CBD=25°
∠ABD=6.2*25
=155°
∠ABD=90+∠EBD
155=90+∠EBD
∠EBD=155-90
∠EBD=65°
Because ∠ FBE and ∠ EBD are congruent, ∠ FBE =65°.
Hence if the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.
