Step-by-step explanation:
yx = k, where k is a real constant.
When y = 30, x = 3.
=> k = (30)(3) = 90.
Hence when y = 6, x = k/y = (90)/(6) = 15.
4/x = 2/7 please help ASAP!!
Answer:
use cross multiplication to solve
4*7 = 2*x (multiply)
28 = 2x (divide both sides by 2 to isolate x )
x = 14 (your answer)

State University has no honors English course but instead places all freshman scoring at least 60 on a proficiency exam (mean=50, standard deviation=10) into an advanced composition course. If the scores are normally distributed and there are 2,500 entering freshman, how many will be put into the advanced course?
Answer:
that put into the advanced course is 396.75
Step-by-step explanation:
The computation of that put into the advanced course is shown below:
P(X>60)
= P((X - mean) ÷ s > (60 - 50) ÷ 10)
= P (Z > 1)
= 0.1587
It could be checked by the standard normal table
Now that put into the advance course is
= 2,500 × 0.1587
= 396.75
Hence, that put into the advanced course is 396.75

Answer:
x = 5
Step-by-step explanation:
The opposite sides of a parallelogram must be parallel to each other, and this is shown by the equivalent opposite interior angles on each side of the bisector.
Since the opposite sides of a parallelogram are parallel, they must be of equal length (this is one of the fundamental properties of a parallelogram).
Therefore, we can set (18x - 5) and (16x + 5) equal to each other in an equation and solve for x.
18x - 5 = 16x + 5Subtract 16x from both sides.
2x - 5 = 5Add 5 to both sides.
2x = 10Divide both sides by 2.
x = 5The value of 5 for x must make ABCD a parallelogram.

Write an equation of the line that passes through the given points. (-1,7) and (3,-5)
Answer:
y=-3x+4
Step-by-step explanation:
First, let's find the slope (m)
(-1,7), and (3,-5)
the formula is: (y2-y1)/(x2-x1)
we can label the points.
x1=-1
y1=7
x2=3
y2=-5
substitute into the equation
m=(-5-7)/(3--1)
m=(-12)/4
m=-3
Now let's use the equation for point-slope form, which is y-y1=m(x-x1)
using the labeled points from above:
y-7=-3(x+1)
do distributive prop
y-7=-3x-3
add 7 to both sides
y=-3x+4
In a basketball game Jamarcus made 15 out of 25 shots and tyrell made 32 out of 50 shots who’s the better shooter
Answer:
Jamarcus is the better shooter
Step-by-step explanation:
Jamarcus is better because he needs 10 more shots to reach 25 while tyrell needs 18 More shots to make 50
Answer:
Tyrell
Step-by-step explanation
Well this is simple you take Jamarcus shots made and divide it into the total shots which is 15/25=0.6 or 60%. So Jamarcus made 60% of the shots attempted. Tyrell made 32 out of 50 shots so that will be 32/50=0.64 or 64%. Since 64%>60% Tyrell is the better shooter
can you find the value x in the f figure
Answer:
[tex]x =[/tex] [tex]16\frac{2}{11}[/tex]
Step-by-step explanation:
According to the image, those are verticle angles, so I came up with this equation that can help me solve this problem:
5x+12+6x-10=180
11x+2=180
11x=178
x=[tex]16\frac{2}{11}[/tex]

-5y + 4 = -11
what is y?
Answer:
3
Step-by-step explanation:
-5y + 4 = -11 Get rid of the numbers to get y alone.
-5y +4 minus 4 = -11 minus 4 Here you are removing the 4 from the left
-5y = -15 Now you will have to get rid of the -5
-5y/(-5) = -15/(-5)
y = 3
Answer:
y = 3
Step-by-step explanation:
-5y + 4 = -11
-4 -4
-5y = -15
--------------
-5 -5
y = 3
How can I tell that a graph is a function or not?
Answer:
You can use the vertical line test, which means anywhere you put it on the graph it should only pass through the line once.
Step-by-step explanation:
This insures that the graph does not have two of the same x values. However if it has two points that have the same x values that means it will not be a function.

STOP RIGHT THERE. Please help me.
Answer:
the answer is B
Step-by-step explanation:
Well we can get rid of A and D because we're not adding money, we're subtracting (thats what a sale is)
So we're left with B and C.
To find what 17% of 3 is, we multiply 3 x 0.17, which totals to 0.51. It can't be C because you find 51% of 3 which is not what we're looking for, so it is B.

Graphs can only provide a limited view of the data.
a. True
b. False
Answer:
Graphs can only provide a limited view of the data.
b. False
Step-by-step explanation:
On the contrary, graphs present better views of the presented data. Mathematically, graphs are methods of visually illustrating data relationships. The main purpose of using a graph is to present complicated data that show trends or relationships between variables. It has been an important tool for presenting data in a visual and easy-to-understand format, without using too much description.
