Line R passing through point P(-2, -1) and point (3,5). Find the slope of line R.

Answer:

j*14 + 8

Step-by-step explanation:

Answer:

Step-by-step explanation:

So if mischievous grows 8 7/12 inches every week, you have to multiply 8 7/12  times 4 (for the 4 weeks).

8 7/12 x 4= 34 4/12

Then add that to the snakes current length.

34 4/12+ 17 2/9=///

1) Change the fractions to have common denominators

4/12 x 3= 12/36

2/9 x 4= 8/36

2) Add. 8+12= 20. Denominators stay the same. 20/36.

3) Add the whole numbers. 34+17=51.

4) Put it all together. 51 20/36.

5) Simplify the fractions. 20 and 36 can be divided by 4.

20/4=5  36/4=9, 5/9

So, 34 4/12+17 2/9= 51 5/9

Mischievous will be 51 5/9 inches after 4 weeks.

To convert into feet, divided 51 by 12.

Answer:

a. 3 cm

b. 6 km

Step-by-step explanation:

to be completely honest, I just shoot my answer based on the pattern.

if you notice that when the scale is 4 cm, the actual distance is 5 km. When the distance is 4 km, the scale should probably be 3 cm. It's the same with the 5 cm scale, then the distance should be 6 km

Step-by-step explanation:

Use ratios to solve it

a)

x = 4*4/5 = 3.2 cm

b)

x = 5*5/4 = 6.25 km

According to the rule, the table is:

x|y

2|3

3|5

4|7

The translation of the rule to a math expression is:

[tex]y = 2x - 1[/tex]

Then, for x = 2:

[tex]y = 2(2) - 1 = 4 - 1 = 3[/tex]

For x = 3:

[tex]y = 2(3) - 1 = 6 - 1 = 5[/tex]

For x = 4:

[tex]y = 2(4) - 1 = 8 - 1 = 7[/tex]

Thus, the table is:

x|y

If 7 seeds are planted, the probability that exactly 3 do grow is;

P(X = 3) = 0.0002

This is a binomial probability distribution problem where;

P(X = x) = ⁿCₓ × pˣ × q⁽ⁿ ⁻ ˣ⁾

We are given;

p = 95% = 0.95

q = 1 - p

q = 1 - 0.95

q = 0.05

Thus If 7 seeds are planted, the probability that exactly 3 do grow is;

P(X = 3) = ⁷C₃ × 0.95³ × 0.05⁽⁷ ⁻ ³⁾

P(X = 3) = 35 × 0.857375 × 0.00000625

P(X = 3) = 0.000187

To four decimal places gives;

P(X = 3) = 0.0002

Answer:  1000001010 base 2

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

Explanation:

There are two methods to solving this problem.

One method is to involve having a list of the powers of 2

And so on.

In that list should be 2^9 = 512. So 512 is a power of 2. It is the largest such power that is just under 522. Subtracting it off gets us

522-512 = 10

So that explains why the 2^9 slot in the answer is a '1'. This is the first '1' mentioned in the answer shown above. Then we have a string of '0's until we reach 1010 at the end. That long string of 0s indicate that we don't have any of the following powers: 2^8, 2^7, 2^6, 2^5, 2^4

It's when we get to 2^3 is when we finally have a power of 2 to add on.

Then note how 10-2^3 = 10-8 = 2

So the last term we need to add on is 2^1 = 2. Note the gap from 2^3 to 2^1 because of the first 0 in 1010

So that's how we end up with 1000001010 as our final answer.

Step-by-step explanation:

When you are subtracting a negative, it is the same as just adding a positive.

[tex]-9\frac{2}{7} + 10\frac{3}{7}[/tex]

We can rearrange the problem to read:

[tex]10\frac{3}{7} -9\frac{2}{7}[/tex]

Now, we can subtract the numbers and fractions separately.

[tex]10+\frac{3}{7} -(9+\frac{2}{7})[/tex]

[tex](10-9)+(\frac{3}{7}-\frac{2}{7} )=1+\frac{1}{7}=1\frac{1}{7}[/tex]

Answer:

9): 64.7

10): 39$

Step-by-step explanation:

Answer:

64.7% and $39

Step-by-step explanation:

Question 9:

This means that the baseball team won 22/34 of their games through their entire season. In order to find the percentages of game they won, you divide 22 by 34, which comes out to 0.64705..., which becomes 64.705%. Rounding this to the nearest tenth, this percentage becomes 64.7%. Therefore, the percentage of games their baseball team is 64.7%.

Question 10:

We can represent this problem as the proportion:

[tex]\frac{27}{69.2} =\frac{x}{100}[/tex]

with x being the original price of the slacks.

We cross multiply to solve this equation. 27 times 100 is 2700. Next, we divide 2700 by 69.2, which comes out to 39.017341. Rounding this to the nearest whole number, this value comes out to 39. Therefore, the original price of these slacks is $39.

Answer:

6.99. You get much more for a cheaper price per unit.
