Answer:
D. Yes; the graph passes the vertical line test.
Step-by-step explanation:
1. A and C are wrong since the number of x-values that a y-value have does not matter when it comes to functions.
2. When doing the vertical line test, it is done by drawing a vertical line (up to down) and then seeing if more than 1 point touches the line.
3. After drawing the vertical line you would see only 1 point touches the line which indicates that the graph passes the vertical line test.
4. Therefore, the answer is "D. Yes; the graph passes the vertical line test."

set of data has a normal distribution with a mean of 56 and a standard deviation of 7. Find the percent of data within the following interval.
from 35 to 77
SOMEONE PLEASE HELP
Answers
Answer:
.99815
which is about
99.815%
Step-by-step explanation:
we are looking for 35<x<77
We need to find (what I think is called) the z score which is acheieved through what I'm pretty sure is called standardizing
What we do is subtract the mean and then divide by the standard deviation
so for 35 we have
(35-56)/7= -3.29
due to the fact that the normal distribution is symmetric this is equal to 1-p(3.29)
to find p(3.29) grab a ztable and get p(3.29)= .9995
1-.9995= .0005
For 77 we have
(77-56)/7=3
grab a ztable and find the 3= .99865
Finally subtract these two to get the final answer
.99865-.0005= .99815
Maggie bought 45 oz of flour for her bakery. She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin. How many muffins did Maggie make if she had 14.72 oz of flour left over?
Answers
Answer:
18 muffins
Step-by-step explanation:
Amount of flour Maggie used
Total amount of flour she bought - Amount of flour left over.
= 45oz - 14.72 oz
= 30.28 oz of flour
She used 17.5 oz to make a loaf of bread, and 0.71 oz for each muffin.
Hence,
Let the number of muffins = x
17.5 + 0.71x = 30.28
0.71x = 30.28 - 17.5
0.71x = 12.78
x = 12.78/0.71
x = 18 muffins
Therefore, Maggie made 18 muffins
What is the greatest common factor of 42, 30, and 45
Answers
Answer:
3
Step-by-step explanation:
Express the numbers as a product of their primes.
42 = 2 × 3 + 7
30 = 2 × 3 × 5
45 = 3 × 3 × 5
Identify the prime factors common to all 3 numbers.
common prime factor = 3 , thus
GCF = 3
Answer: 3
Step-by-step explanation: The factors of 30 are 1. 2. 3. 5. 6. 10, 15, 30
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42
The factors of 45 are 1, 3, 5, 9, 15, 45
As you can see they all share the factors of 1 and 3. Since 3 is the greatest number of the factors all of them share it is the greatest common factor.

Since we are rounding: 5 or more...raise the score, 4 or less...let it rest.
Well 7 is greater than 5 so we round 2 up to 3

Here’s why:
We would first locate the hundreds place. The hundreds digit would be '2'.38,273
If the tens place (the digit to the right) is greater than or equal to 5, then we would round up. If the tens place is less than or equal to 4, we round down. Since the 7 is greater than or equal to 5, we would round up.⸻⸻⸻⸻

Johnny Bravo bought Amazon 25 shares at $50. He sold them at $2346 a few years later. How much money did he make on this stock?
Answers
Answer:
$1096
Step-by-step explanation:
If Johnny Bravo bought Amazon 25 shares at $50, the cost price is expressed as;
Cost price of 25shares = 25 * 50
Cost price of 25shares = $1,250
If he sold them at $2346 a few years later
Profit = Selling price - Cost price
Profit made = 2346 - 1250
Profit made = $1096

Answer:
(x, y) = (59/45, 11/15) ≈ (1.311, 0.733)
Step-by-step explanation:
A graphing calculator shows us the solution is not integer values, so we may find it easiest to solve these equations using the "cross-multiplication method."
Writing the equations in general form, we have ...
3x -4y -1 = 0
6x +7y -13 = 0
Then we can form an array of the coefficients, repeating the first column:
[tex]\begin{array}{cccc}3&-4&-1&3\\6&7&-13&6\end{array}[/tex]
Forming differences of cross products involving adjacent pairs of columns gives ...
d1 = (3)(7) -(6)(-4) = 45
d2 = (-4)(-13) -(7)(-1) = 59
d3 = (-1)(6) -(-13)(3) = 33
Then the solutions are found from ...
1/d1 = x/d2 = y/d3
or
x = d2/d1 = 59/45
y = d3/d1 = 33/45 = 11/15
The solution is (x, y) = (59/45, 11/15) ≈ (1.311, 0.733).

Additional comment
This takes longer to explain than to do. One reason we like it is that the number of math operations is slightly smaller than the number of math operations required for substitution or elimination. It is especially nice when the solution is not a pair of integers.

3) A box contains 4 yellow marbles, 2 blue marbles, and 3 red marbles. If a marble is drawn randomly from
the box, but the marble drawn is replaced. What is the probability of drawing 2 yellow marbles and 1 red
marble?
Answers
Hey buddy I am here to help!
yellow marbles = 4
blue marbles = 2
red marbles = 3
total marbles = 9
1 random marbles taken off probability left = 8/9
1 random marble taken off probability = 1/9
marble if replaced = + 1
if one marble if replaced then = 8/9 + 1/9 = 9/9 that means total marbles r 9
yellow marbles drawn off = 2
so... 4 - 2 = 2 marbles left
red marbles taken off = 1
so... 3 -1 = 2 marbles left
probability/answer = 3/9 = 1/3

Solve 270=3e^2.4K to the nearest hundredth
If you can solve this for me could you please give steps so I can understand, please and thank you so much!
Answers
Given:
The equation is:
[tex]270=3e^{2.4K}[/tex]
To find:
The solution for the given equation to the nearest hundredth.
Solution:
We have,
[tex]270=3e^{2.4K}[/tex]
Divide both sides by 3.
[tex]\dfrac{270}{3}=e^{2.4K}[/tex]
[tex]90=e^{2.4K}[/tex]
Taking ln on both sides, we get
[tex]\ln (90)=\ln e^{2.4K}[/tex]
[tex]\ln (90)=2.4K[/tex] [tex][\because \ln e^x=x][/tex]
Divide both sides by 2.4.
[tex]\dfrac{\ln (90)}{2.4}=K[/tex]
[tex]\dfrac{4.4998}{2.4}=K[/tex] [tex][\because \ln (90)\approx 4.4998][/tex]
[tex]1.874916667=K[/tex]
Round the value to the nearest hundredth (two decimal place)
[tex]K\approx 1.87[/tex]
Therefore, the value of K is 1.87.
if the volume of a sphere is 36 pi cubic inches, what is the radius?
Answers
Answer:
r = 3 in
Step-by-step explanation:
The volume (V) of a sphere is calculate as
V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )
Here V = 36π , then
[tex]\frac{4}{3}[/tex]πr³ = 36π ( multiply both sides by 3 to clear the fraction )
4πr³ = 108π ( divide both sides by 4π )
r³ = [tex]\frac{108\pi }{4\pi }[/tex] = 27 ( take the cube root of both sides )
r = [tex]\sqrt[3]{27}[/tex] = 3
