Answer:

Soln:

Step-by-step explanation:

Here,

Base(b) =9

Opposite/Perpendicular (p)= x

Hypotenus (h) = 24

We know,

(p)^2 = (h)^2 - (b)^2

(x)^2 = (24)^2 - (9)^2

x^2 = 576 - 81

x^2 = 495

x = root under 495

Answer:

1- 22.2486  2- No

Step-by-step explanation:
1:

[tex]b = \sqrt{ c^{2}- a^{2}[/tex]

C is the hypotenuse, or longest side of the triangle (24).

A is the one length we have besides the hypotenuse(9).

[tex]b = \sqrt{ 24^{2}- 9^{2}[/tex]

b = 22.2486

2:
No, because if it was a Pythagorean triple, it would follow the equation [tex]a^{2} +b^{2} =c^{2}[/tex].

[tex]9^{2} + 22.2485^{2} \neq 24^{2}[/tex].

Answer:

100

Step-by-step explanation:

Range = highest - lowest (R = H - L)

In order, the set is 0, 20, 40, 76, 90, 100

100-0 = 100

Answer:

100

Step-by-step explanation:

Range = Highest value -lowest value

100-0=100

Answer:

The graph of a linear equation is a straight line.  The "solution" to a system of two linear equations is the point where the two lines cross.  If the two lines are parallel, they never cross; hence parallel lines have no solution.  Two lines are parallel if they have the same slope (the m value in y = mx+b).  One of your equations is y = -2x + (you left the y-intercept out).  The slope is -2.  So any line with a slope of m = -2 will be parallel to this line and will not cross it.  The second line also needs a different value of b, the y-intercept.  Otherwise it is the same line and every point is a solution.  So if your equation is:

y = -2x + 1

Then any equation of the form y = -2x + b, b≠1 will create a system with no solution.  Hence the values of m and b are m = -2, b ≠ 1.

Answer:

1st one with triangles is not a good model of 3÷1/4

Answer:

Step-by-step explanation:

If you look at the triangles, the lines in them are NOT equal, and not split into fourths.

The 3/8 chance is the probability of winning a scholarship.

The odds of winning a scholarship is 3/5

The probability is given as:

P(Win) = 3/8

The odds is calculated using:

Odds = P(Win)/[1 - P(Win)]

This gives

Odds = 3/8/[1 - 3/8]

Evaluate the difference

Odds = (3/8)/(5/8)

Evaluate the quotient

Odds = 3/5

Hence, the odds of winning a scholarship is 3/5

Answer:

x = -4

Step-by-step explanation:

x+y = -10       or     y = -10 - x

substitute this into the second equation

x      -    y    = 2

x      -  (-10-x) = 2

2x + 10 = 2

2x = -8

x = - 4

both catch 7 pokemon per day

Answer:  0.2066

Step-by-step explanation:

Probability of Rebecka selecting a poodle = 5/11

Probability of Aaron selecting a poodle = 5/11

Both select one puppy at random with replacement, so their choices are independent.

Thus, probability that both select a poodle = [tex](5/11)\times(5/11)[/tex]

[tex]= 25/121 \approx 0.2066 \ $or 20.66\%[/tex]

Answer:

7 trees.

Step-by-step explanation:

Number < 7 ft consists of the first 2 stems:

5 || 8   - 1 tree

6|| 2,3,7,8,9,9  -  6 trees

= 1 + 6

= 7.

The number of trees that are less than 7 trees as shown in the stem-and0leaf plot is: 7 trees.

In a stem-and-leaf plot, data points are represented in leaves and stems. For example, representing height of trees as 5 || 8, means a data point representing a height of a tree measuring 5 ft and 8 inches tall.

From the stem-and-leaf plot given, the data points that are below 7 feet are 7 in number, which range from 6 ft and 9 inches down to 5 ft and 8 inches.

The answer is: 7 trees.

Answer:

7

Step-by-step explanation:

We can setup this equation as x representing his number.  (x+13) * 3 = 9x -3.

Now, we just need to solve for x.  

3(x+13)=9x-3

x+13=3x-1

14=2x

x=7

Answer:

D.

Step-by-step explanation:

1) the required probability can be calculated as sum of two probabilities:

P=p1+p2, where p1 - when the 1st attempt is correct, p2 - when the 2d attempt is correct;

2) p1=1/10; p2=1/9, then the required probability:

P=1/10 + 1/9 ≈ 1/5.

Answer:

A

Step-by-step explanation:

If we start from top to bottom all we have to do is check which ones are not equal.

The first one is

[tex]a^2(b+c) = a^3(\frac{b}{a}+c)[/tex]
If we multiply is out we get

[tex]a^2b+a^2c = a^3*\frac{b}{a}+a^3c\\\text{which turns into}\\a^2b+a^2c=a^2b+a^3c[/tex]

That is NOT equal to the other. Making the answer A.

-7 + 4(n-1).  Use this and plug in 10 for n, making it

-7 + 4(9)
