Answer: 7:5
Step-by-step explanation:
what is the value of x? enter your answer in the box.______ units
The value of x is 8 units by using Pythagorean theorem.
If x and 6 are the lengths of the legs of a right triangle and the length of the hypotenuse is 10, then we can use the Pythagorean theorem to find the value of x.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.
So in this case:
x^2 + 6^2 = 10^2
Expanding the squares and solving for x:
x² + 36 = 100
x² = 100 - 36
x² = 64
x = [tex]\sqrt{64}[/tex]
x = 8
So the value of one leg of x is 8 units and other which is given is 6 units.

1) Andrea bought tacos from a food truck and left a 25% percent tip of $2.00
What was the price of Andrea's tacos, before tip?
2) Savanna had 40 iris blooms last year. This year, she had 15% more iris blooms.
How many more iris blooms did Savanna have this year?
1. Answer: The price of Andrea's tacos is $8.
Step-by-step explanation:
Hi, to answer this question we have to write an equation with the information given:
Tip amount: $2.0
Percentage: 25% = 0.25 (decimal form, 25/100=0.25)
So, if we multiply the taco's price (x) by the percentage (0.25) we will obtain the amount of the tip (2).
Mathematically speaking:
x (0.25) = 2
Solving for x
x = 2/0.25
x = 8
The price of Andrea's tacos is $8.
2. To solve this problem what you can do is the following rule of three:
40 iris blooms -----> 100%
x iris blooms -------> 115%
Clearing the value of x we have:
x = (115/100) * (40)
x = 46
Then, comparing with last year we have:
40-46 = 6
Answer:
Savanna had this year 6 more iris blooms than last year.

a frequency distribution usually has equal bin widths. T/F
A frequency distribution usually has equal bin widths is the true statement.
All the line charts are not used for the purpose of cross-sectional data. A scatter plot is very useful in this process of visualizing trends over time. A scatter plot essentially requires two quantitative variables (i.e., not categorical data).
The difference of the maximum and minimum values is divided by the number of bins.
1. Identify the maximum and minimum values of the quantitative data.
2. Subtract the minimum value from the maximum value to get the difference
3. Divide the difference by the number of bins to get the approximate width of each bin
The width of the bins in a frequency distribution of quantitative data can be estimated by dividing the difference between the maximum and minimum values of the data by the desired number of bins. This will provide an approximate size for each bin, that can then be used to construct the frequency distribution.

When Xochitl runs the 400 meter dash, her finishing times are normally
distributed with a mean of 84 seconds and a standard deviation of 2.5
seconds. Using the empirical rule, determine the interval of times that
represents the middle 68% of her finishing times in the 400 meter race.
Answer: The empirical rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.
In this case, the mean of Xochitl's finishing times is 84 seconds and the standard deviation is 2.5 seconds, so the interval that represents the middle 68% of her finishing times is:
[84 - 2.5, 84 + 2.5] = [81.5, 86.5]
So, we can conclude that the middle 68% of Xochitl's finishing times in the 400 meter race fall between 81.5 and 86.5 seconds.

What is the probability that the first such number is on the 3rd roll? startfraction 1 over 27 endfraction startfraction 4 over 27 endfraction startfraction 8 over 27 endfraction startfraction 19 over 27 endfraction.
The probability of rolling a 9 or higher on the 3rd roll is 4/27, or approximately 14.8%.
Probability is a branch of mathematics that deals with determining the likelihood or chance of an event occurring. It is often expressed as a fraction or a percentage.
Conditional probability is the probability of an event happening given that another event has already happened.
The probability of not rolling a 9 or higher on the first roll is 8/12 or 2/3, as there are 8 numbers on the cube that are less than 9.
The same is true for the second roll, so the probability of not rolling a 9 or higher on the first two rolls is (2/3) * (2/3) = 4/9.
The probability of rolling a 9 or higher on the third roll is 4/12 or 1/3, as there are 4 numbers on the cube that are 9 or higher.
So, the probability of rolling a 9 or higher on the third roll given that the previous two rolls did not result in a 9 or higher is

Answer:
y = -3x + 10
where y = Value and x = Position
or
Value = - 3(Position) + 10
Step-by-step explanation:
We can determine a linear equation for this table in slope-intercept form
The slope intercept form of a linear equation is
y = mx + b
y is referred to as the dependent variable and x the independent variable
Here m is the slope which is the rate of change of y with respect to x
b = y-intercept which is the value of y when x = 0
For the given table it appears that the value is dependent on the position
So the independent variable, let's call it x, is position
The dependent variable, y, is value
Plugging values of x, y into the generalized equation
y = mx + b
At x(position) = 1, we get y = 7
==> 7 = m(1) + b
==> 7 = m + b
== m + b = 7 ............................. (1)
At x = 3, y = 1
==> 1 = m(3) + b
==> 1 = 3m + b
==> 3m + b = 1 ..............................(2)
If we subtract equation 1 from equation (2) we get
(3m + b) - (m + b) = 1 - 7
3m - m + b - b = -6
2m + 0 = -6
2m = -6
m = -6/2 = -3
So we now know m = -3 we can write the equation as
y = -3m + b
To find b, plug in any value of x and corresponding y from the table and solve for b. remember that x is position and y is value
Let's choose the last entry x = 9, y = -17
Plugging these into y = -3x + b gives
-17 = -3(9) + b
-17 = -27 + b
Switch sides:
- 27 + b = -17
Add 27 to both sides:
- 27 + 27 + b = -17 + 27
b = 10
So the equation for the table is
y = - 3x + 10
or in terms of the table
Value = - 3(Position) + 10
You can check this is correct by choosing a value for position from the table and seeing the equation value is consistent with the given value

Step-by-step explanation:
The first piece of advice I have for you is to have confidence in yourself that you will succeed. That is what learners and tutors here at brainly are for. To help out.
Now to explanation of the problem and solution
The linear equation of a graph can be written in a couple of ways. On ios the standard form which is of the form
Ax + By = C where A, B and C are constants
The other is in slope-intercept form which is written as
y = mx + b
Here m is the slope which is also referred to as rise/run. I will explain these terms as we solve the problem
b is the y-intercept. This is the y-value at which the line crosses the y-axis. It corresponds to the value of y when x = 0
Sometimes the graph will not show the complete line so we cannot determine where the line crosses the y-axis. In this case this determination is a cinch
Looking at the graph, we see the line crosses the y-axis at (0,0) which is the origin
Therefore the y-intercept is 0 and hence b=0
Hence we get the line equation as
y = mx + b
==> y = mx + 0
==> y = mx
Let's find m, the slope:
Take any two points on the line. Here two points have been identified as (1, 6) and (4, 24)
The difference in y-values for these two points is 24 - 6 = 18.
This difference in y-values is known as the rise since it is measured vertically
The corresponding difference in x values is 4 - 1 = 3
This is referred to as run because it is measured horizontally
The slope m = rise/run
Here m = 18/3 = 6
Therefore plugging in m = 6 the equation in slope-intercept form is
y = 6x
Slope has another meaning. It signifies the rate of change
In this particular case in real-world terms it means that the cost of sandwiches is proportional to the number of sandwiches
Every sandwich you purchase will cost you $6 more
So the cost per sandwich is $6
For 1 sandwich -→ $6,
For 2 sandwiches → $12
For 7 sandwiches → $42
and all this is clearly evident in the graph
Hope that helps you and good luck on all your subjects

The sum of 4 44 consecutive integers is 198 198198. What is the fourth number in this sequence?.
With the sequence having sum of four consecutive integers as 198 , the fourth integer in the sequence is calculated to be 51.
Let's call the first integer in the sequence "x". Since the integers are consecutive, the next three integers in the sequence would be "x + 1", "x + 2", and "x + 3". The sum of these four integers can be represented as:
x + (x + 1) + (x + 2) + (x + 3) = 198
Expanding and simplifying the left side of the equation, we get:
4x + 6 = 198
Subtracting 6 from both sides of the equation, we get:
4x = 192
Dividing both sides of the equation by 4, we get:
x = 48
So the first integer in the sequence is 48. To find the fourth integer in the sequence, we add 3 to the first integer:
x + 3 = 48 + 3 = 51
So the fourth integer in the sequence is 51.
