Using the conversion factors, 454 grams of butter is used by the chef each day.
What are conversion factors?A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an equal value. For instance, 12 inches equals one foot when converting between inches and feet.So, grams of butter used each day:
19 pounds = 8618.26 gramsThen,
1 pound = 8618.26/191 pounds = 453.592 gramsRounding off: 454 gramsTherefore, using the conversion factors, 454 grams of butter is used by the chef each day.

4. A student asks, “If the average income of 10 people is $10,000 and one person gets a raise of $10,000, is the median or the mean changed and, if so, by how much?
Since we don't know the specific income of each person in the sample, we don't know for sure if the median will change. Nevertheless, the mean will surely raise.
Since the current average income is $10,000, if one of them gets a raise of $10,000, then the sum of all incomes would be $100,000+$10,000=$110,000. And the new average income will be:
[tex]\frac{110,000}{10}=11,000[/tex]Then, the mean increases by $1,000, and we can't say anything about the median.

The graph of y = 3x² + 7x + m will have two x-intercepts if m < 49/12.
The given function is,
y = 3x² + 7x + m
Having two x-intercepts means that the value of y should be 0.
So, we can write,
3x² + 7x + m = 0
Now, this has become a quadratic equation and it will have two zeroes according to the question,
As we know, the condition of quadratic to have two different values of x is,
0 < √(b²-4ac)
Where,
a = 3
b = 7
c =m
Putting all the values,
√(7²-4(3)(m)) > 0
Squaring both sides,
7²-4(3)(m) > 0
49-12m > 0
49/12 > m.
So, the graph will have two intercepts if m < 49/12.

can someone help me find the formule pls
The linear equation in point-slope form of the given condition is y = 30x + 170. The number of words after 8 days will be 410.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Let's represent the number of days by x and the number of words by y.
At day 1 (x = 1) ⇒ Number of words (y = 200)
At day 1 (x = 2) ⇒ Number of words (y = 230)
The point-slope form of a linear equation is given as,
y = mx + c
Where m is the slope, while c is the y-intercept.
Substitute,(1,200) in y = mx + c
200 = m(1) + c
Now slope m = (230 - 200)/(2 - 1) = 30
200 = 30(1) + c
c = 170
Therefore, the equation become,
y = 30x + 170
The number of words after 8 days will be,
y = 30(8) + 170 = 410
Hence "The linear equation in point-slope form of the given condition is y = 30x + 170. The number of words after 8 days will be 410".

We need to compute the probability that event A occurs but event B does not occur.
i.t., to find = P(A ∩ B')
We know that, P(A ∩ B') = P(A) - P(A ∩ B)
For mutually exclusive events, P(A ∩ B) = 0
So, P(A ∩ B') = P(A)
P(A ∩ B') = 0.33
Also, we need to compute the probability that either B occurs without A occurring or A and B both occur.
P(B ∪ A') + P(A ∩ B)

A.
The question asks us to find the probability of getting at least 4 or an odd number after throwing a die.
This is easily gotten using the OR probability of two events which states:
[tex]\begin{gathered} P(A\text{ OR B) = P(A) + P(B) - P(A AND B)} \\ \text{if A = rolling at least 4} \\ B\text{ = rolling odd number,} \\ \\ P(\text{rolling at least 4 OR rolling odd number) = } \\ P(\text{at least 4) + P(odd number) - P(at least 4 AND odd number)} \end{gathered}[/tex]To get at least 4, it means the possible values we can have are: 4, 5, 6.
To get an odd number, it means the possible values we can have are: 1, 3, 5.
From both set of possibilities, 5 is common. We need to subtract the probability of getting a 5 in both situations to prevent duplication.
Thus, we can compute each probability:
[tex]\begin{gathered} P(any\text{ number)= }\frac{1}{6} \\ \\ P(at\text{ least 4)= P(4) OR P(5) OR P(6) = P(4) + P(5) +P(6)} \\ \therefore P(at\text{ least 4)= }\frac{1}{6}+\frac{1}{6}+\frac{1}{6}=\frac{3}{6} \\ \\ P(\text{odd number) = P(1) OR P(3) OR P(5) = P(1)+P(3)+P(5)} \\ \therefore P(\text{odd number)= }\frac{1}{6}+\frac{1}{6}+\frac{1}{6}=\frac{3}{6} \\ \\ P(\text{at least 4 AND odd number) = }\frac{1}{6} \\ \\ \\ \therefore P(\text{at least 4 or odd number)=}\frac{3}{6}+\frac{3}{6}-\frac{1}{6}=\frac{5}{6} \end{gathered}[/tex]Therefore, the probability of getting at least 4 or an odd number is 5/6
B:
This part of the question asks us to find the probability of rolling an even number or a number at most 5.
We, once again, take a look at the possibilities to solve this question.
Possibilities of getting an even number are: 2, 4, or 6
Possibilities of getting at most 5 are: 1, 2 , 3, 4, 5.

The equation that models the height f(t) (in feet) of an object t seconds after it is when dropped from the top of the tower is,
f(t) = -16t² + 1776
Part a: time when object hit the ground.
