There 24 purple flowers, some yellow, and some red. If 48% of the flowers are purple, how many flowers are there in all?
Answer: 50 flowers in total
24 is 48% of the total.
it has to be close to 48 because 48% is almost 50% which is a half.
idek my logic is weird but it's 50 flowers in total :)

PLEASE HELP ILL GIVE BRAINLIEST
Answer:
Option (2)
Step-by-step explanation:
Given equation of a line → y = [tex]\frac{1}{2}x+3[/tex]
Slope of the line 'm₁' = [tex]\frac{1}{2}[/tex]
Let the equation of a line perpendicular to the given line is,
y = m₂x + b
Here, m₂ = Slope of the perpendicular line
b = y-intercept
By the property of perpendicular lines,
m₁ × m₂ = -1
Therefore, [tex]\frac{1}{2}\times m_{2}=-1[/tex]
m₂ = -2
Equation of the perpendicular line will be,
y = -2x + b
Since the perpendicular line passes through a point (-3, 4)
4 = 6 + b
b = -2
Therefore, equation of the perpendicular line wiil be,
y = -2x - 2
Option (2) will be the answer.
which one is the right answer
Answer:
Use a website called Desmos and click on the graphing calculator
Step-by-step explanation:
Type all of those equations in the graphing calculator and the one that is the same as the graph above is the correct one!
Answer:
Since it’s negative it will have a negative slope so it would be down to a, b, c
Then look at the y intercept which is 2 and it’s positive so it would be c

Step-by-step explanation:
What percent of 60 is 15
What percent means x/100.
The word "of" means times.
The word "is" means equals.
So we have x/100 · 60 = 15 or 60x/100 = 15.
The rest of the work is attached below, just solve the equation.

If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is need to cover the entire wall?
Answer:
4 gallons
Step-by-step explanation:
multiply 1/2 by 8 to find the number
Answer:
One gallon of paint can cover [tex]\frac{1}{4}[/tex] of a wall.
Step-by-step explanation:
start by writing the ratio:
[tex]\frac{1}{2\\}[/tex] : [tex]\frac{1}{8}[/tex]
There are two halfs in one gallon so you multiply the [tex]\frac{1}{2\\}[/tex] by 2. And whatever you do to one side must be done to the other so:
[tex]\frac{1}{2\\}[/tex]×2 : [tex]\frac{1}{8}[/tex]×2
Evaluate.
1: [tex]\frac{2}{8}[/tex]
this can be further simplified to
1: [tex]\frac{1}{4}[/tex]

Answer:
x = 37
Step-by-step explanation:
Use the theorem formula
a^2+b^2=c^2
35^2 + 12^2 = c^2
1225 + 144 = c^2
1369 = c^2
divide by square root
c = 37
so x = 37

Consider the arithmetic sequence:
10, 12, 14, 16, ...
If n is an integer, which of these functions generate the sequence?
Choose all answers that apply:
A a(n) = 16+ 3n for n > -2
b(n) = 14 + 2n for n > -1
c(n) = 10 + 3n for n > 0
D
d(n) = 8 + 2n forn > 1
Answer:
Answer: D
Step-by-step explanation:
Arithmetic Sequences
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
[tex]a_n=a_1+(n-1)r[/tex]
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:
[tex]a_n=10+(n-1)2[/tex]
Operating:
[tex]a_n=10+2n-2[/tex]
[tex]a_n=8+2n[/tex]
Answer: D
Answer:
d(n)=8+2n for n >1

Line 1: (2,2), (-4,5)
Line 2: (4.-9), (-6,-4)
Answer:
parallel
Step-by-step explanation:
find the slope of each line
Line 1 (5-2)/(-4-2) = 3/-6 =-1/2
Line 2 (-4--9)/(-6-4)= 5/-10 = -1/2
4x+2y=12
step by step slope intercept form
Answer:
y = -2x + 6
Step-by-step explanation:
4x + 2y = 12
2y = -4x + 12
y = -2x + 6

The random variable X represents the number of test is a patient entering a hospital have along with the corresponding possibilities find the mean and standard deviation
Complete question :
The random variable x represents the number of tests that a patient entering a hospital will have along with the corresponding probabilities. Find the mean and standard deviation.
x 0 1 2 3 4
P(x) 3/17 5/17 6/17 2/17 1/17
Answer:
1.59 ; 1.09
Step-by-step explanation:
The Mean :
E(X) = Σx*p(x)
(0*3/17) + (1 * 5/17) + (2*6/17) + (3*2/17) + (4*1/17)
= 1.58823
= 1.59
Standard deviation = sqrt(Var(x))
Var(X) = Σx²*p(x) - E(x)²
= {(0^2*3/17) + (1^2 * 5/17) + (2^2*6/17) + (3^2*2/17) + (4^2*1/17)} - 1.59^2
= 3.7058823 - 2.5281
= 1.1777823
Standard deviation = sqrt(1.1777823)
= 1.0852567
= 1.09
