Answer:
0.70631
Step-by-step explanation:
Given that :
Mean (m) = 20 km
Standard deviation (s) = 6 km
Probability that car travels between 15 and 28 km
Using the relation to obtain the standardized score (Z) :
p(x < 15)
Z = (x - m) / s
Z = (15 - 20) / 6
= - 0.8333
p(Z < - 0.833) = 0.20242 ( Z probability calculator)
(x < 28)
Z = (x - m) / s
Z = (28 - 20) / 6
= 1.333
p(Z < 1.333) = 0.90873 ( Z probability calculator)
0.90873 - 0.20242 = 0.70631
An equation of a line can be written in point slope form given any point (_,_) on the line and the slope of the line ___.
Answer:
.... given any point (x,y) on the line and the slope of the line m.
Step-by-step explanation:
Its because a coordinate's variables are (x,y) due it's position on the graph on the x-axis and y-axis; and the slope of the line is called m in general (it's just a mathematical term/variable due to how it is defined in formulas)

In 2005, 120 students at Lincoln High School
had smart phones. By 2010, 345 students in the
same school had smart phones. Which of the
following best describes the annual rate of change
in the number of smart phones students had from
2005 to 2010 at Lincoln High School?
A) The average increase in the number of smart
phones per year is 40.
B) The average increase in the number of smart
phones per year is 45.
C) The average increase in the number of smart
phones per year is 50.
D) The average increase in the number of smart
phones per year is 55.
Answer:
The average increase in the number of smart
phones per year is 45
Step-by-step explanation:
Given that :
Number of students who had phones in 2005 = 120
Number of students who had phones in 2010 = 345
(345 - 120) / 5
225 / 5
= 45
Hence, average increase in number of smartphones per year = 45

EASY QUESTION- MERRY XMAS
Answer:
The answer will be B.
Step-by-step explanation:
When the number is with the x, it moves the graph in the horizontal direction, and when the number is NOT with the x, it moves the graph in the vertical direction.
So, since -6 is with the x, it is moving the graph Right 6 units. Changing it to 4 units results in the the graph moving 2 units left from 6 units.
The -1 is NOT with the x, so it moves the graph down 1 unit. Taking out the -1 (so putting a 0) results in the graph moving 1 unit up from -1.
So, the graph translated up 1 unit and left 2 units.

9 is subtracted by the sqaure of a number
Answer:
I believe it is x^2-9
Step-by-step explanation:
Since we don't have a specific "number" you use x. It says it's squared to put an exponent of 2. It also says that 9 is subtracted by it so put -9.

Option B is correct as the y-intercept is 6.
Find the area of the circle.
Answer:
A=346,6 in²
Alternative C
Step-by-step explanation:
Length of circunference:
L=2πR, where r is the radius
Area of circle:
A=πR²
We know that L=66
66=2πR, then:
πR=33in
[tex]R=\frac{33}{\pi }[/tex]
Thus:
[tex]A=\pi (\frac{33}{\pi} )^{2}[/tex]
[tex]A=\frac{1089}{\pi} \\\\A=346,63[/tex]
Find the inverse of the function.
Answer:
The option 'b' is true.
Step-by-step explanation:
Given the expression
[tex]f\left(x\right)=\frac{2}{x+7}[/tex]
A function g is the inverse of the function f if for y=f(x), x=g(y)
[tex]y=\frac{2}{x+7}[/tex]
Replace x with y
[tex]\:x=\frac{2}{y+7}[/tex]
solve for y
[tex]y=\:\:\frac{2}{x}-7[/tex]
Thus,
[tex]f^{-} (x)=\frac{-7x+2}{x}[/tex]
Therefore, option b is true.

Answer:
The y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.
Step-by-step explanation:
Given the function
[tex]y=3x+2[/tex]
the y-intercept of the function can be determined by setting x=0 and solving for y.
so
[tex]y=3x+2[/tex]
[tex]y=3(0)+2[/tex]
[tex]y=0+2[/tex]
[tex]y=2[/tex]

The angles of AABC have the extended ratio of 7:8:15, respectively. Calculate the value for each of the angles A, B,
and C. Remember the angles in a triangle sum to 180 degrees!
Answer:
Step-by-step explanation:
Remark
A B C have to be multiplied by the same something. No matter what they are multiplied by the sum will be 180 degrees.
Equation
Let the angle ratios be multiplied by x
7x + 8x + 15x = 180
30x = 180
x = 180/30
x = 6
Answer
7*6 = 42
8*6 = 48
15*6 = 90
Total 180 as it should
At Thompson Pass, 12 inches of snow fell during a 16 hour period. At this rate how much snow would fall in 24 hours? Pls help!
Answer:
18 inches of snow
Step-by-step explanation:
First, you'll have to find how much snow falls in a hour: 12/16 = .75 inches
Secondly, you'll multiply that by 24 to find the inches in a full day: 24 x .75 = 18
Answer:
18 inches of snow
Step-by-step explanation:
12:16
24 if you know the butterfly method which is 12/16=24 multiply 12 and 24 together and get 288 and then divide it by 16 which you get 18 inches of snow

Answer:
Clearly show i can't see ur answer
Answer:
x = 60
Step-by-step explanation:
These angles are alternate exterior angles because they are on the opposite side of the transversal line and on the outside of a set of two non-transversal lines.
The alternate exterior angles theorem explains that if a pair of non-transversal lines are parallel, then the alternate exterior angles are congruent.
We can use the following equation to solve:
46 = 3x-14
Simplify.
60 = 3x
x= 60

Which point is the incenter of Triangle JKL ?
Enter your answer in the box.
point
Answer:
Point N. I took the test!
Step-by-step explanation:
It is found that in-center of the triangle JKL is point N.
What is a triangle?A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
We are given a triangle JKL.
In triangle JKL, they have drew perpendicular bisectors of each side of the triangle.
Also we are given the angle bisectors of the each of angles.
Since perpendicular bisector is a line that intersect a segment into two equal parts and also perpendicular to it.
Also we know that the in-center is the point forming the origin of a circle inscribed inside the triangle. which is constructed by taking the intersection of the angle bisectors of the three vertices of the triangle.
We can see that angle bisectors are intersecting at a point N.
Therefore, It is found that in-center of the triangle JKL is point N.

Are the ratios 7:6 and 17:12 equivalent?
yes
no
Answer:
no
Step-by-step explanation:
A ratio can be written as a fraction:
7:6 can be written as 7/6, and 17:12 can be written as 17/12.
Now multiply the numerator and denominator of 7/6 by 2 to get an equivalent fraction and ratio: 14/12
14/12 is not equal to 17/12, so
7:6 and 17:12 are not equivalent
