Answer:
I belive it is 105
Step-by-step explanation:
ok so by spliting this up into where the 9 lengh ends.that recctangle is now 9 by 6,to find area you multiply them,that gets you 54.Now for the other part you want to fill it in,when you do that the area is 6 by 11 what equals 66 but ou have to take away the corner making it 51.Now we add those together and you have 105.
It is the first option- 12 times one fourth the quotient of 6 and 2
4/29 is the probability that a student who did not complete the homework passed the test.
<u>Step-by-step explanation:</u>
It is given that,
There are 29 students in a math class.
Two types of students who passed the test and are not passed the test.
The other two types of students are who completed the assignment and did not complete the assignment.
So, the given data can be formed as a table.
- There were 22 students who passed the test.
- There were 20 students who completed the assignment.
- There were 18 students who passed the test and also completed the assignment.
Passed the test Not passed the test Total
Completed assignment 18 - 20
Not completed assignment x - -
Total 22 - 29
Now, you need to find the probability that a student who did not complete the homework passed the test.
⇒ No.of students completed assignment passed the test / Total students.
<u>To find the no.of students completed assignment passed the test :</u>
Let 'x' is the no.of students completed assignment passed the test.
⇒ 18+x = 22
⇒ x = 22 - 18
⇒ x = 4
∴ P(students completed assignment passed the test) = 4 / 29.
Descriptions 1, 2, 3, and 5 are accurate, though 5 is ambiguous.
_____
Description 4 goes with (7x)² = 49x², not 7x².
Description 6 goes with 5·8 + x² + (2x + 8) = x² +2x +48, not 40x² +100x +40.
The description for 5 is accurate, but could also be applied to y² + 3(y - 4), which is why it can be considered to be ambiguous. There are a number of ways to resolve the ambiguity, but they were not used here.
Answer:
y = 2/5x + 39/5
Step-by-step explanation:
point slope form is y = mx + b
so far we have y = 2/5x + b
m is slope which is given. We need to find b which is y-intercept.
They give us the point (-2,7). We can plug this into the equation to find b.
7 = 2/5(-2) + b
7 = -4/5 + b
b = 39/5
The equation now looks like y = 2/5x + 39/5
