Answer:
The probability that a person adds both sugar and honey is 0.04.
Step-by-step explanation:
P(H) means "probability that a random person adds honey"
P(S) means "probability that a random person adds sugar"
P(H or S) means "probability that a random person adds AT LEAST ONE OUT OF honey and sugar"
P(H and S) means "probability that a random person adds BOTH honey and sugar"
We can simplify it as "percentage of people who add" instead of "probability that a random person adds", and then it should be clear to us that
P(H or S) = P(H) + P(S) - P(H and S)
The equation comes from the face that if we want to compute percentage of people who add at least one sweetener, we can sum people who add honey and people who add sugar, but we would have counted people who use both TWICE, so we can correct by subtracting. As follows:
P(H and S) = P(H) + P(S) - P(H or S)
P(H and S) = 0.15 + 0.68 - 0.79 = 0.83 - 0.79 = 0.04
So the probability that a person adds both sugar and honey is 0.04.

Do mechanical waves travel faster or slower in more dense media?
Answers
When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

Answers
Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.
Use the distance formula to find the distance to the nearest tenth, from R17, -2) to W(-2, 3).
Answers
Answer:
17.7
Step-by-step explanation:
I'm assuming you meant R(17, -2) to W(-2, 3). Here the x-coordinate changes by 17 - (-2), or 19, and the y-coordinate by 5. Think of these as the legs of a right triangle. The distance between these points is the length of the hypotenuse of this triangle: d = √(5^2 + 17^2)
or √314, which, to the nearest tenth is 17.7.

If 5% of the 300 students at NewzBrain Middle School were absent from school, how many of the students were in school?
Answers
Answer:
285 students were in school.
Step-by-step explanation:
5%=0.05
0.05*300=15
300-15=285
There were 285 students in school.
Given that 5% of the 300 students were absent, we can calculate it as follows:
= 5% of 300
= (5/100) x 300
= 0.05 x 300
= 15
Therefore, there were 15 students absent from school.
Now, the In school students
Total students - Absent students = In-school students
300 - 15 = 285
So, there were 285 students in school.

Write the number using scientific notation:
23,000
Answers
The scientific notation representation of 23,000 is 2.3 x 10⁴
To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.
Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.
Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.

Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS,and 25 cents per off-peak time SMS.if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month, what will her monthly bill come to?
Answers
Answer:
Anita's monthly bill will be $164.25.
Step-by-step explanation:
Since Anita has a cellphone contract that costs her R100 per month plus 85 cents per peak time SMS, and 25 cents per off-peak time SMS, if she sends 45 SMSs during peak time and 105 SMSs during off-peak time In a month To determine what will her monthly bill come to, the following calculation must be performed:
100 + (0.85 x 45) + (0.25 x 105) = X
100 + 38.25 + 26.25 = X
138.25 + 26.25 = X
164.25 = X
Therefore, her monthly bill will be $ 164.25.
