Is (3, 7) a solution to x² + 1 = y ?

Answers

Answer 1

Answer:

No

Step-by-step explanation:

3² + 1 = 7? Nopeeeee

3 * 3 = 9, that alone is bigger than 7.

3 * 3 + 1 = 10.

10 is bigger than 7.

Answer 2

Answer:

No

Step-by-step explanation:

To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.

[tex](3)^{2} +1=7[/tex]

9 + 1 = 7

[tex]10\neq 7[/tex]

Therefore, (3, 7) is not a solution.

2) 3 : 15 = 1 : 5

3) 22 : 38 = 11 : 19

4) 2 : 5 = 26 : 65

Step-by-step explanation:

2) 5, 3, 1, 15

3 : 15 = 1 : 5

If you simplify 3 : 15 you get 1 : 5 and 1 : 5 = 1 : 5.

3) 19, 22, 11, 38

22 : 38 = 11 : 19

If you simplify 22 : 38 you get 11 : 19 and 11 : 19 = 11 : 19.

4) 65, 2, 26, 5

2 : 5 = 26 : 65

If you simplify 26 : 65 you get 2 : 5 and 2 : 5 = 2 : 5.

Are the events "selecting a female" and "selecting a students who has brown eyes" independent?​

Answers

Answer:

No, the events are not independent.

Step-by-step explanation:

Suppose that there are two events, A and B.

Such that first happens the event A and then the event B.

If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.

In this case, if we have only the event "selecting a student who has brown eyes"  (at random)

The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:

P = 91/200 = 0.455...

Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.

In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:

P = 32/90 = 0.355...

So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

Consider the glven solids with the dimensions shown. Which solids are similar?
A. only figure 1 and figure 2
B. only figure 1 and figure 3
C. only figure 2 and figure 3
D. all three figures​

Answers

Answer:

A) only figure 1 and figure 2

Step-by-step explanation:

Answer: Choice A) only figure 1 and figure 2

===========================================================

Explanation:

Let's assume that figure 2 is similar to figure 3.

If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.

Figures 2 and 3 cannot be similar for that reason.

Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.

We eliminate answers B, C and D. The only thing left is choice A.

-------------------

To verify choice A is true, we divide each corresponding piece like so

Horizontal: 15/10 = 1.5Vertical: 24/16 = 1.5Slanted: 12/8 = 1.5

Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.

Graph the inequality on a number line z<1 1/4

Answers

Answer:

Step-by-step explanation:

The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.
