Where [tex]\pi[/tex]= 3.14
r= 7cm
To find the area, we would input the values together

There is a “family” of Z distributions?
Answers
Reason:
There is only one Z distribution, which is also known as the standard normal distribution. This distribution has a mean of mu = 0 and a standard deviation of sigma = 1. So unless you consider a family to only have one member, then I'd consider the statement your teacher gave you to be false.
On the other hand, if we were talking about the student T distribution, then this is a family of function curves. The reason being is that the degrees of freedom (df) will change the shape of said curve. The value of df will depend on the sample size n. Recall that df = n-1. As n gets larger, then the T distribution curves will slowly start to look like the Z distribution. For n > 30, the difference is so very minor that it's easier to swap over to the Z distribution even if you don't know sigma.
In other words, there is a family of T distribution curves in which slowly approach to mimicking the Z distribution curve when n is large (usually n > 30).

Determine if (6, 2) is a solution to the system of equations.
2x + y = 10
3x + 2y = 10
Answers
Answer:
no
Step-by-step explanation:
plug 6 in for x and 2 in for y, as (x, y) = (6, 2)
first equation:
y = 1 * y
2(6) + 1(2) = 10
12 + 2 = 10
14 = 10
this is false
second equation:
3(6) + 2(2) = 10
18 + 4 = 10
22 = 10
this is false
for this to be a solution, it must fit into both equations. as this fits into neither, this is not a solution

If the radius of the circle is 6 feet. Then the area of the circle will be 113.097 square feet.
What is a circle?It is the centre of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.
The radius of the circle is 6 feet.
Then the area of the circle will be
Area = πr²
where r is the radius of the circle. Then we have
Area = π × 6²
Area = 36π
Area = 113.097 square feet

Find the amount of decay:
1200 - 900 = 300
Divide amount of decay by original amount:
300/1200 = 0.25
The percent of decay is 25 %
The decay factor is 1.00 a 0.25 = 0.75

A circle with a centre 0, has an equation x2 + y2 = 25
The coordinate A (4,3) is on the circumference of the circle.
Find the equation of the tangent at point A.
Answers
The linear equation of the tangent at point A is given by:
[tex]y = \frac{-4x + 25}{3}[/tex]
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, to find the slope, we need to find the derivative at (4,3), using implicit differentiation. Hence:
[tex]2x\frac{dx}{dx} + 2y\frac{dy}{dx} = 0[/tex]
[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]
[tex]\frac{dy}{dx} = -\frac{4}{3}[/tex]
Then:
[tex]y = -\frac{4}{3}x + b[/tex]
We use point (4,3) to find b, hence:
[tex]y = -\frac{4}{3}x + b[/tex]
[tex]3 = -\frac{16}{3} + b[/tex]
[tex]b = \frac{25}{3}[/tex]
Hence, the equation is:
[tex]y = \frac{-4x + 25}{3}[/tex]

It is incorrect. The variable would come first in the expression “a number” (n) “increased by” (+) “nine” (9).
It is incorrect. The phrase “increased by” refers to the inequality symbol “greater than” (>), not addition.
It is correct. A number increased by nine (n + 9) is the same as nine increased by a number (9 + n).

Marni has 24 ounces of walnuts. she needs 14 ounces for one recipe and 1/2 pounds for another. how many total ounces does she need to make her recipes?
Answers
The total ounces she needs to make her recipes is 22 ounces
Calculating quantityFrom the question, we are to determine how many total ounces Marni needs to make her recipe
From the given information,
Marni has 24 ounces of walnuts
Also,
She needs 14 ounces for one recipe
and
1/2 pounds for another
First, we will convert 1/2 pounds to ounces
NOTE: 1 pound = 16 ounces
∴ 1/2 pound = 8 ounces
Then, we can rewrite that
She needs 14 ounces for one recipe
and
8 ounces for another
The total ounces she needs to make her recipes = 14 ounces + 8 ounces
The total ounces she needs to make her recipes = 22 ounces
Hence, the total ounces she needs to make her recipes is 22 ounces

Triangle ABC is dilated by a scale factor of 1.5 to create triangle A'B'C'. Which of
the following it not a true statement?
A. The image is larger than the pre-image.
B. The orientation of triangle ABC is preserved.
C. Segment AB is congruent to segment A'B'.
D. The angle measures in triangle ABC are equal to the angle measures in triangle
A'B'C'.
Answers
Answer:
C. Segment AB is congruent to segment A'B'.
Step-by-step explanation:
Since ABC is being dilated by 1.5, it means that A'B'C will be bigger than ABC.
So, since A'B'C will be bigger than ABC, it sides will also be bigger than the sides in ABC.
And since the sides/segments are bigger than the original, they are not congruent (congruent means equal).
