Answer:
Binomial, with [tex]p = 0.9, n = 15[/tex]
Step-by-step explanation:
For each student, there are only two possible outcomes, either they own a cellphone, or they do not. The probability of a student in the sample owning a cellphone is independent of whether other students own a cellphone or not. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution:
Probability of exactly x sucesses on n repeated trials, with p probability.
90% of students now own a cell phone.
This means that [tex]p = 0.9[/tex]
Fifteen students are to be selected at random from a large university.
This means that [tex]n = 15[/tex]
What is the appropriate distribution for X?
Binomial, with [tex]p = 0.9, n = 15[/tex]

What is the slope of the graph of the line y=2x-3
Answer:
3/2 ??
Step-by-step explanation:
Hello there!
This equation is written in slope-intercept form (y=mx+b) which means it's easy to identify the slope.
In slope-intercept form, m is the slope.
Therefore, the slope of this line is 2.
Hope it helps.

R'after the translation (x,y) + (x-17-1), followed by a dilation by a scale factor of 2 centered at the origin?
Answer:
To find the scale factor for a dilation, we find the center point of dilation and measure the distance from this center point to a point on the preimage and also the distance from the center point to a point on the image. The ratio of these distances gives us the scale factor, as Math Bits Notebook accurately states.

On a map, 1 inch equals 8 miles.two cities are 6 inches apart on the map.what is the actua distance between the two cities?
Answer:
48 Miles
Step-by-step explanation:
I assume you are asking for the distance in miles between the two cities.
1 Inch = 8 Miles,
Then 6 Inches = 8 Miles * 6
If the cities are 6 inches apart, the actual distance is 48 miles.

Ashton has an offer to buy an item with a sticker price of $4900 by paying
$140 a month for 48 months. Which of these groups of values plugged into
the TVM Solver of a graphing calculator will give him the correct answer for
the interest rate being offered?
A. N=4; 1% = ; PV=-4900; PMT=0; FV=140; P/Y=1; C/Y=12; PMT:END
B. N=4; 1% = ; PV=-4900; PMT=0; FV=6720; P/Y=1; C/Y=12; PMT:END
O C. N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
O D. N=4; 1% = ; PV=0; PMT=-4900; FV=140; P/Y=1; C/Y=12; PMT:END
We can plug them into the TVM Solver as follows:
N=4; 1% = ; PV=0; PMT=-4900; FV=6720; P/Y=1; C/Y=12; PMT:END
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To use the TVM (Time Value of Money) Solver of a graphing calculator to find the interest rate being offered, we need to input the correct values in the calculator.
PV = -$4900 (negative because it represents a payment)
PMT = $140
N = 48
FV = $0 (because we are assuming Ashton will pay off the item in full)
Using these values, we can plug them into the TVM Solver as follows:
N = 48; I/Y = 1%; PV = -$4900; PMT = $140; FV = $0; P/Y = 1; C/Y = 12; PMT: END
Thus,
We can solve for I/Y, which gives us an interest rate of approximately 13.41%.

Step-by-step explanation:
Area of rectangle = length x width
(10 x 14. Add on the length of the triangle base)
Area of triangle = 1/2 base x height
(1/2*4 x 2. Notice the missing lengths on either side of 6 would be 2. 2 is also the height of the triangle)
In the figure, you have a rectangle with two equal triangles cut out at the bottom.
Find the area of the rectangle and subtract the area of the two triangles.
Area of rectangle 10x14= 140
Area of one triangle (1/2)4 x 2 = 4
Area of rectangle - two times area of triangle
140 - 2(4) =
140 -8 = 132
