Find the distance between the two points rounding to the nearest tenth (if necessary). (-1,5) and (-7, -1)
Distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 +(y_2-y_1)^2}[/tex]
Now replace the variables with the numbers (When you replace the numbers, it doesn't matter which is the first variable and second variable. Just do whatever is easiest).
[tex]d = \sqrt{(-1-(-7))^2+(5-(-1))^2}\\d = \sqrt{(-1+7)^2+(5+1)^2}\\d = \sqrt{6^2+6^2}\\d = \sqrt{36+36}\\d = \sqrt{72} \\d = 8.5[/tex]
Thus, the distance between the two points is 8.5

Maria wrote the equation log (startfraction x over 2 endfraction) log (startfraction 20 over x squared endfraction) = log 8 what is the solution to maria’s equation?
The solution to maria’s equation [tex]\rm log\frac{x}{2} +log\frac{20}{x^{2} } = log8[/tex] by using the properties of the logarithm is 5/4.
What is a logarithm?A logarithm is the exponentiation inverse function that can be expressed by the exponent or power to which a base must be raised to yield a number.
It is given that
[tex]\rm log\frac{x}{2} +log\frac{20}{x^{2} } = log8[/tex]
Using properties of a logarithm, we get
[tex]\rm log x + log y=logxy[/tex]
[tex]\rm log[\frac{x}{2} \times\frac{20}{x^{2} }] = log8\\\rm log[\frac{10}{x}] = log8[/tex]
on comparing
10/x = 8
x = 10/8
x = 5/4
Hence, the solution to maria’s equation [tex]\rm log\frac{x}{2} +log\frac{20}{x^{2} } = log8[/tex] is 5/4.

What is a normal distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
The proportions of multiple samples of registered voters who vote are normally distributed, with a mean proportion of 0.38 and a standard deviation of 0.0485.
The z-score is given as
[tex]z = \dfrac{x - \mu}{\sigma}[/tex]
Then the probability of a sample is chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 will be
For x = 0.37, then we have
[tex]z = \dfrac{0.37 - 0.38}{0.0485} \approx -0.206[/tex]
For x = 0.39, then we have
[tex]z = \dfrac{0.39- 0.38}{0.0485} \approx 0.206[/tex]

Answer:
B) 70 °
Step-by-step explanation:
Given that the triangles AOC and BOC are congruent, the triangles OA and OB are likewise congruent and both represent the radius of a circle. Geometry tells us that an angle formed by two radii that are parts of two congruent triangles has the following dimensions:
m ∠ AOB = 2 · x (1)
Where x is the measure of angle BOC, in degrees.
And the measure of the angle AOC is: ( x= 70°)
∠ AOC = 70°

What is the value of y in the equation 5y - 3y + 1 = -4y + 13?
Answer:
y = 2
Step-by-step explanation:
5y - 3y + 1 = -4y + 13
We only have addition and subtraction so move the terms on the other side of the equal sign with changed sign. +1 will be -1 and -4y will be +4y
terms with y = terms without y
5y -3y +4y = 13 -1
6y = 12
y = 12/6
y = 2
An IV solution of 320 mL at a drip rate of 25 gtt/min using a tubing factor of 10 gtt/mL has been ordered to be initiated at 1145. Calculate the infusion time. (Round your answer to the nearest tenth of an hour.)
The infusion time for the IV solution that was prescribed = 128 mins.
Calculation of IV infusion timeTo calculate the infusion time the formula for IV drip rate is used which is;
Drip rate = volume/time × Drop factor
Drip rate = 25gtt/min
Volume = 320mL
Drop factor= 10 gtt/mL
Time = ?
From the formula above, make time the subject of formula. That is,
Time = vol × drop factor/drip rate
= 320 × 10/25
= 3200/25
= 128 mins
Therefore, the infusion time for the IV solution that was prescribed = 128 mins

The table below shows the number of people that attended a family reunion each year. (Need help ASAP)
The table of attendees in the family reunion is a linear regression
The equation of the line of best fit is y = 4.9x + 112186 attendees are expected in the 15th yearHow to draw the scatter plot?To do this, we represent the years on the x-axis and the attendees on the y-axis
See attachment for the scatter plot
The equation of the line of best fit?The scatter plot passes through the points
(0, 112) and (5, 136.5)
Start by calculating the slope, m using:
m = (y2 - y1)/(x2 - x1)
This gives
m = (136.5 - 112)/(5 - 0)
m = 4.9
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 4.9 * (x - 0) + 112
y = 4.9x + 112
Hence, the equation of the line of best fit is y = 4.9x + 112
The attendees in the 15th yearThis means that x = 15.
So, we have:
y = 4.9 * 15 + 112
Evaluate
y = 186
Hence, 186 attendees are expected in the 15th year

Answer:
Step-by-step explanation:
(a + b)³ - (a - b)³ = a³ + 3a²b + 3ab² + b³ - [a³ - 3a²b + 3ab² -b³]
= a³ + 3a²b + 3ab² + b³ - a³ + 3a²b - 3ab² + b³
= a³ - a³ + 3a²b + 3a²b + 3ab² - 3ab² + b³ + b³
Here, the underlined terms will be cancelled.

The height of a triangle is 4 times its base. If the triangle has an area of 162 ft2, find the length of the base and the height.
Answer:
base= 9 ft
height= 36 ft
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Let the base and the height of the triangle be b and h ft respectively.
162= ½ ×b ×h
Given that h= 4b,
162= ½ ×b ×4b
162= ½(4b²)
162= 2b²
Divide both sides by 2:
b²= 81
Square root both sides:
b= 9
h= 4b
h= 4(9)
h= 36
Thus, the lengths of the base and height are 9 and 36 ft respectively.
