Please help! What is 2250/7 as a mixed number?
Answer:
321.
Step-by-step explanation:
First, divide 2250 by 7 to see how many times 7 can go in. You should get 321 and 3 as your remainder. To put it into mixed number format, it would put 321 as your whole number and your remainder divided by 7. It would be 321 3/7. Hope this helps :)
Answer:
321 3/7

(I think the following is correct haha. I know what to do, but the exact wording they used confused me slightly. Have a nice day!)
The { percent } should be written as a { fraction } before dividing.
5 ÷ 20% = { 5 ÷ [tex]\frac{1}{5}[/tex]} = { 25 }
Answer:
The percent should be written as a fraction before dividing.
5 ÷ 20% = 5 ÷ [tex]\frac{1}{5}[/tex] = 25

The value of the expression 17 − {2 + 2 [−1 (7 − 10) ] 2} is 3.
What is an expression?An equation is a way of writing a statement with two or more expressions with operations such as addition, subtraction, multiplication, and division.
Example: 2x + 3 x 4 - 3 is an expression.
We have,
= 17 − {2 + 2 [−1 (7 − 10) ] 2}
We will first solve,
(7 - 10) = 7 - 10 = -3
Now,
= 17 - {2 + 2[-1 x -3] 2}
We will solve [-1 x -3],
[-1 x -3] = 3
Now,
= 17 - {2 + 2 x 3 x 2 }
We will solve { 2 + 2 x 3 x 2 }
{ 2 + 2 x 3 x 2 } = 2 + 12 = 14
Now,
= 17 - 14
Subtracting we get,
= 3
Thus,
The value of the expression 17 − {2 + 2 [−1 (7 − 10) ] 2} is 3.

The height of a tree sapling was 3.15 inches last year. This year, the height is 5.38 inches. How much did the height of the tree sapling increase? Find the difference.
Answer:
2.23 inches
Step-by-step explanation:
Difference means subtraction and you subtract the smaller number from the bigger number. 5.38 - 3.15 = 2.23 in.
Answer:
2.23 inches
Step-by-step explanation:
We will subtract 3.15 from 5.38 because the problem is asking for the increase. We will take the new height and subtract the old height to see the difference.
5.38 - 3.15 = 2.23 inches

Eunice, Helen and Essel shared $14,000 among themselves. Eunice had twice as much as Helen and Helin had twice as Essel. How much did Helen get?
Answer:
Helen amount = $2,000
Step-by-step explanation:
Helen amount = x
Eunice amount = 2 ( Helen amount) = 2x
Helin amount = 2 (Eunice amount) = 2(2x) = 4x
x + 2x + 4x = $14,000 Check Helen = x = $2,000
7x = $14,000 Eunice = 2x = $4,000
x = $14,000 ÷ 7 Helin = 4x = $8,000
x = $2,000

4 of the students in a Biology class passed a Biology test. If these students are 25% of all the students in the class, how many students are in this Biology class? Round your answer to the nearest whole number if necessary.
Answer:
625=63 to the nearest whole number
Step-by-step explanation:
= 4/100×25%
= 625
= 63 to the nearest whole number
Answer:
16
Explanation:
Reasoning:
You know that 4 students = 25% of the class,
and that ? students = 100% of the class,
So you would want to plan it out like this:
4 ----- 25%
? ----- 100%
This is how you would solve it:
4 x 100
25
Multiply 100 x 4 = 400
Divide 400/ 25 = 16

Thirty-three percent of all students at a high school like beef stew. Out of 300 students, 40 are selected randomly and asked whether they liked beef stew. If liking beef stew is a success, what is the probability of a failure for this binomial experiment? 0. 33 0. 40 0. 57 0. 67.
Probabilities are used to determine the chances of an event.
The probability of a failure for the binomial experiment is (d) 0.67
The probability (p) that a student likes beef stew is given as:
[tex]\mathbf{p = 33\%}[/tex]
Using the complement rule, the probability (q) that a student does not like beef stew is calculated as:
[tex]\mathbf{q =1-p}[/tex]
Substitute 33% for p
[tex]\mathbf{q =1-33\%}[/tex]
Express 33% as decimal
[tex]\mathbf{q =1-0.33}[/tex]
Subtract 0.33 from 1
[tex]\mathbf{q =0.67}[/tex]
From the question, the probability (q) that a student does not like beef stew represents failure
Hence, the probability of a failure is (d) 0.67

There can only be one possibility to make this equation make sense. If we were to do any number greater than 0, the equation wouldn't work.
If c = 0

Could someone please help mee
Step by step
Let Q be the point (a, b). Since the midpoint of P (2, 3) and Q (a, b) is (4, 6), we have
(2 + a)/2 = 4
(3 + b)/2 = 6
Solve for a and b :
(2 + a)/2 = 4
2 + a = 8
a = 6
(3 + b)/2 = 6
3 + b = 12
b = 9
So the coordinates of Q are (6, 9).
the probability that a new microwave oven will stop working in less than 2 years is 0.05. the probability that a new microwave oven is damaged during delivery and stops working in less than 2 years is 0.04. the probability that a new microwave oven is damaged during delivery is 0.10. given that a new microwave oven is damaged during delivery, what is the probability that it stops working in less than 2 years?
Answer:
0.40
Step-by-step explanation:
0.04 divided by 0.10 = 0.4
Using conditional probability, it is found that there is a 0.4 = 40% probability that it stops working in less than 2 years.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Damaged during delivery.Event B: Stops working in less than 2 years.0.1 probability of being damaged during delivery, hence [tex]P(A) = 0.1[/tex].
0.04 probability of being damaged during delivery and stop working, hence [tex]P(A \cap B) = 0.04[/tex]
The conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.1} = 0.4[/tex]
0.4 = 40% probability that it stops working in less than 2 years.

Answer:
a) I am sorry, but I don't know this one.
b) y = mx + b
=> b = y-intercept = 0
=> m = slope = Rise/Run
=> Rise/Run = 120/65
=> Rise/Run = 24/13
=> Slope = 24/13
=> Our Equation: y = 24x/13
c) After drawing the trend line, we can conclude that if 100 costumers were served, the amount of tips would be about $185
d) To use a regression calculator, we must be given a table with x and y values. Then we insert the values in the calculator so that it can give us the whereabouts of a point and it can give us the trend line. After the trend line is given, we can make a prediction.

What are the solutions to the system of equations?
y=x^2-5x+6
y=-4x+6
A (0,6) and (1,2)
B (-1,0) and (6,0)
C (-1,0) and (0,6)
D (0,-1) and (6,0)
Step-by-step explanation:
y = x² - 5x + 6
y = -4x + 6
x² - 5x + 6 = -4x + 6
x² - x = 0
x(x - 1) = 0
x = 0 and x = 1
y = -4x + 6 and y = -4x + 6
y = -4(0) + 6 and y = -4(1) + 6
y = 0 + 6 and y = -4 + 6
y = 6 and y = 2
Solution = (0,6) and (1,2)

If A = {1,20,30..} and B = {4,6} find n(A-B)?
Explanation:-
Given sets are A = { 1,20,30}
B = { 4,6}
Now,
A-B = { 1,20,30} -{ 4,6}
⇛ A-B = { }
Since there are no common elements in both A and B sets
⇛Number of elements in A-B = 0
⇛n(A-B) = 0
Therefore, n(A-B) = 0
ADDITIONAL COMMENT:
Points to know:-
Empty set :-
A set having no element is called an empty set or void set or null set .It is denoted by phi or { } The cardinal number of the Null set = 0Difference of two sets :-
A and B are two sets ,The set of elements which belongs to A and does not belong to B is called The difference between the two sets A and B and it is denoted by A-B.Cardinal number of a set :-
