Joe's final exam has true/false questions, worth 2 points each, and multiple choice questions, worth 5 points each. Let x be the number of true/false
he gets correct, and let y be the number of multiple choice questions he gets correct.
He needs more than 90 points on the exam to get an A in the class. Using the values and variables given, write an inequality describing this.
This is the inequality
2x + 5y ≥ 90
5. A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. Wha
is Plyellow)?
2
8
5
5
Answer:
i cant rlly see the question bc its cut out but i yhink its 8
Step-by-step explanation:
total Amount of Marbles in the bag is:
5 + 3 = 8
So, since there are 5 Red marbles, the probability of drawing one is 5 / 8.
Now that you pulled that marble out, you have 7 marbles total left in the bag, 4 of those are read (5 originally, minus the one you took out.
So, the probability of the second round is 4/7.
To find the overall probability, you multiply those probabilities together:
4/7*5/8 = 20/56

Does anybody know the answer to this question
Answer:
A
Step-by-step explanation:
A set of data is summarized by the stem and leaf plot below.
Stem Leaf
1 1 2 3 4 4 5 5 7 8 8 9 0 1 2
2 4 6 8 9 9 0 3 4
3 4 4 4 6 7 7 8 9
Provide your answer below:
There are __________ values in the data set which are greater than or equal to 20 and less than or equal to 29. There are _____________ values in the data set which are greater than or equal to 30 and less than or equal to 39. There are ___________ values in the data set which are greater than or equal to 10 and less than or equal to 19.
Answer:
30 values ; greater than or equal to 10 and less Than or equal to 39
Step-by-step explanation:
Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.
The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10
The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39

-2x + 1 = -x + 8 solve for X?
Answer:
x = -7
Step-by-step explanation:
-2x + 1 = -x + 8
* isolate the variable using inverse operations *
step 1 add 2x to each side
-2x + 2x cancels out
-x +2x = x
now we have 1 = x + 8
step 2 subtract 8 from each side
8 - 8 cancels out
1 - 8 = -7
we're left with x = - 7

Answer: 1/36
Step-by-step explanation:
Your going to multiply 1/6 x 1/6 and you will get 1/36, because there are 6 slots, and you spin on x once, there is a 1/6 chance you will spin on it again, so that keeps a the 6/6 for all of the letters. But we are looking for f, there is also a 1/6 percent chance that it might land on that, 1/6 x 1/6 = 1/36
Answer:
Step-by-step explanation:
36 - 4
Step-by-step explanation:
(6x - 2)(6x + 2)
= (6x)(6x) + (6x)(-2) + (2)(6x) + (-2)(2)
= 36 - 12x + 12x - 4
= 36 - 4

You have been given the task of finding out what proportion of students that enroll in a local university actually complete their degree. You have access to first year enrolment records and you decide to randomly sample 110 of those records. You find that 87 of those sampled went on to complete their degree. a)Calculate the proportion of sampled students that complete their degree. Give your answer as a decimal to 3 decimal places. Sample proportion
Answer:
The proportion of sampled students that complete their degree is 0.791.
Step-by-step explanation:
A proportion is the number of desired outcomes divided by the number of total outcomes.
a)Calculate the proportion of sampled students that complete their degree.
110 students sampled.
87 went on to complete their degree.
p = 87/110 = 0.791
The proportion of sampled students that complete their degree is 0.791.

You're making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3
kinds of meat. How many different sandwiches could you make? Assume multiple kinds of
breads/cheese/meats are not mixed in a sandwich.
Answer:
12 different types of sandwich could be made.
Step-by-step explanation:
Since I am making a sandwich at the cafeteria where they have 2 kinds of bread, 2 kinds of cheese, and 3 kinds of meat, to determine how many different sandwiches could I make the following calculations must be performed:
Bread x cheese x meat = X
2 x 2 x 3 = X
4 x 3 = X
12 = X
Therefore, 12 different types of sandwich could be made.
6 A train has 1 first-class carriage and 6 standard carriages. The first-class carriage has 64 seats. are being used. Each standard carriage has 78 seats. in each carriage are being used. Are more than half the seats on the train being used?
Answer:
YES
Step-by-step explanation:
(3/8)·64 = 24 seats in the first class carriage are being used.
(7/13)·(78)·3 = 126 seats in the standard carriages are being used, for a total of ...
24 + 126 = 150 . . . occupied seats
The number of available seats is ...
64 +3·78 = 298
so half the seats on the train will be 298/2 = 149 seats.
150 > 149, so more than half the seats on the train are being used.

Question 4 of 12
A line on a coordinate plane has a y-intercept of -6 and a slope of 4. Which of the following models the slope - intercept form of the line?
А
y= 4x + 6
B
y=6x +4
bok
y=-6x +4
y= 4x - 6
Answer:
y = 4x - 6
Step-by-step explanation:
Given the following data;
Slope, m = 4
Intercept, c = -6
To write the equation of line in the slope-intercept form;
The standard equation of straight line is given by the formula;
y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
Substituting the values, we have;
y = 4x + (-6)
y = 4x - 6
