REMEMBER THIS!!! ITS SUPPPER IMPORTANT
Answer:
[tex]\boxed {\sf m= -3}}[/tex]
[tex]\boxed {\sf b= 4}[/tex]
Step-by-step explanation:
The equation of the line is in slope intercept form or:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
Essentially:
The coefficient to x, or number being multiplied is the slope The number added or subtracted from the x term is the y-interceptThe line given is:
[tex]y= -3x+4[/tex]
-3 is the coefficient of x and 4 is being added to -3x.
The slope (m) is -3 and the y-intercept (b) is 4.

Given that z is a standard normal random variable, find the value of z for each situation. a. The area to the right of z is 0.01.
Answer: =1.34
Step-by-step explanation:
In standard density curve
P(Z<z) = Area left of z, P(Z>z) = area right of z.
P(Z<z) +P(Z>z) =1
Given: z is a standard normal random variable.
To find : value of z if rea to the right of z is 0.01.
i.e. P(Z>z) =0.01
P(Z<z) =1-0.01 = 0.09
from z-score table, z value for this is 1.34.
Hence, z= 1.34

Find the domain of the function f(x)=[tex]\sqrt{x^3-16x}[/tex] . What is the least value of x in the domain?
Least Value=
Answer:
Please check the explanation.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\sqrt{x^3-16x}[/tex]
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.Now, determine non-negative values for radicals so that we can sort out the domain values for which the function can be defined.
[tex]x^3-16x\ge 0[/tex]
as x³ - 16x ≥ 0
[tex]\left(x+4\right)\left(x-4\right)\ge \:0[/tex]
Thus, identifying the intervals:
[tex]-4\le \:x\le \:0\quad \mathrm{or}\quad \:x\ge \:4[/tex]
Thus,
The domain of the function f(x) is:
[tex]x\left(x+4\right)\left(x-4\right)\ge \:0\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-4\le \:x\le \:0\quad \mathrm{or}\quad \:x\ge \:4\:\\ \:\mathrm{Interval\:Notation:}&\:\left[-4,\:0\right]\cup \:[4,\:\infty \:)\end{bmatrix}[/tex]
And the Least Value of the domain is -4.

Help ASAP The ratio of two side lengths for the triangle given.Solve the variable.
Answer:
a = 3
Step-by-step explanation:
AB/AC = 7/8 = 14a/48
7/8 = 14a/48
Multiply both sides by 8.
7 = 14a/6
Multiply both sides by 6 and switch sides.
14a = 42
a = 3

Hope this helps :)
10 times as much as 3 ten thousand is equal to 300,000.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the number is 10 times as much as 3 ten thousand. The number will be calculated as below:-
3 ten thousands = 30,000
30,000 x 10 = 300,000
Therefore, 10 times as much as 3 ten thousand is equal to 300,000.

Water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. Which would not be a proportion you could use to solve for the gallons of water going over the waterfall in 2 2/3 hours? There are multiple answers.
Answer: See explanation
Step-by-step explanation:
You didn't give the options but let me help out.
First, we need to convert 2 2/3 hours to minutes. This would be:
= 2 2/3 × 60 minutes
= 8/3 × 60 minutes
= 160 minutes
Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:
= (162 1/2 × 2 2/3hours) / 15 minutes
= (162 1/2 × 160) / 15
= 1733 1/3 gallon

Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.Which of the following best describes an anecdote?
Answer:
25 feet by 4 feet
Step-by-step explanation:
Answer:
This shape is an irregular polygon. This means we have to find the area of the whole shape and then subtract the missing parts to get the correct answer.
First, we have to find the area of the whole shape (a rectangle). The formula for a rectangle's area is:
The length of the shape is 19 ft, and the width is 29 ft. Now, we apply the formula to those numbers:
Now that we know that the area of the whole polygon is 551 square feet, we have to find the area of:
1. The first missing triangle
2. The second missing triangle
3. The missing rectangle
Add all of those areas together, and then subtract them from 551 and we have the answer.
First, we find the area of the missing triangle in the top left hand corner. The area formula for a triangle is
So, we have to find the base and the height. We see that part of the whole polygon's width is 4 ft, which is not missing, so we subtract that from the total width, 19 ft.
This means that the triangle's base is 15 ft. Now, we have to find the height. We can easily see that the height is 15 ft, as it says so in the picture.
Now, we just have to apply the formula:
So, we have our first area, 112 square feet.
Now we have to find the area of the second missing triangle in the bottom right corner.
We know that the base is 4 ft, as it says so in the picture. The height is 24 ft. We know that the total height of the polygon is 29 ft, and we see a shaded part of 25 ft in height. So:
According to this equation, we have 4 ft in height. Using the area formula for triangles, here is our equation:
This equation states that our second area is 8 square feet.
Now, we just have our last area to find, the missing rectangle. According to all of the previous information, and the picture, we see that the width is 15 ft and the height is 14 ft. Now we apply the area formula for rectangles:
Lastly we add up all of our areas: 112.5 square feet, 8 square feet, and 210 square feet.
Then, we subtract 330.5 from 551:
The answer is 220.5

In a farm, ratio of number of cows to number of hens is 2:3. If the number of legs is 40 more than number of eyes, total of how many hens are there in the farm?
Answer:
30 hens, 20 cows.
Step-by-step explanation:
Step one:
let the number of cows be x
and the number of hens be y
Each cow has 2 eyes, each hen has 2 eyes also.
the total number of eyes is
2x+2y
Each cow has 4 legs, each hen has 2 legs.
the total number of legs is
4x + 2y
Step two:
the number of legs exceeds the number of eyes by 40:
4x+2y - (2x+2y) = 40
open bracket
4x+2y-2x-2y=40
4x-2x=40
2x=40
Divide both sides by 2
x=40/2
x=20
Step three:
we know also that x = 2/3*y, so y = 3/2*x = 3/2 * 20 = 30
30 hens, 20 cows.
Check:
60 + 40 eyes = 100, 60 + 80 legs = 140legs.
