Tom wins at chess 180 times in every 250.Daisy wins three quarters of the time.Jacob wins 328 times in every 400?Work out who has the best percentage score.
Answer:
Jacob has the best percentage score of 82%
Step-by-step explanation:
Tom wins at chess 180 times in every 250
Daisy wins 3/4 of 180 times
Jacob wins 328 times in every 400
Tom's percentage score = [tex]\frac{180}{250} * 100[/tex] = 72%
Daisy wins [tex]\frac{3}{4} * 180 = 135[/tex] times
Daisy's percentage score = [tex]\frac{135}{250} * 100[/tex] = 54 %
Jacob's percentage score = [tex]\frac{328}{400} * 100[/tex] = 82%
∴ Jacob has the best percentage score.
Examine the graphs. Determine whether each function is discrete, continuous, or neither discrete nor continuous. Then state the domain and range of each function.
Hey there! I'm happy to help!
Discrete data are data that are usually counted and are represented by points that are not connected by a line.
Continuous data are data that are represented by a straight line.
Our graph has a continuous function because it is made of continuous.
In a function, the domain is all of the x-values and the range is all of the y-values.
With discrete data, the domain and range are usually more finite, and with continuous data, it is usually infinite.
What x-values on this graph include any possible number. If we follow the arrow on the bottom left side of our line, it will go down forever and go in the direction of infinitely many negative x-values. The same goes for the other direction with the other side of our arrow.
So, our domain is going to be -∞ ≤ x ≤ ∞.
If we look at our range, we have the same thing happening. We will have infinite negative y-values and infinitely positive as our arrow goes infinitely in both directions.
So, our range is going to be -∞ ≤ y ≤ ∞.

Answer:
a) C = 1.40 + .4M
b) $4.60
c) 46.5 <= M (miles)
Step-by-step explanation:
a) Cost = initial fee + 0.40 * miles OR
C = 1.40 + .4M
b) C = 1.40 + .4M
C = 1.40 + .4 * 8
C = 1.40 + 3.20 = 4.60
c) C <= 20 so
20 <= 1.40 + .4M
20 - 1.40 <= .4M
18.60/.4 <= M
46.5 <= M
There are 35 houses in a neighborhood AT&T providers Internet service to 1/5 of the houses spectrum provides Internet service to 2/7 of the houses the remaining houses use hotspot as your Internet provider in this neighborhood how many houses use hotspot is there Internet provider
Total number of houses use hotspot is 18 houses
Step-by-step explanation:
Given that;
Number of total houses = 35
AT&T providers Internet service = [tex]\frac{1}{5}[/tex] of total house
Spectrum providers Internet service = [tex]\frac{2}{7}[/tex] of total house
Find:
Total number of houses use hotspot
Computation:
Number of houses AT&T providers Internet service = [tex]35 \times \frac{1}{5}[/tex]
Number of houses AT&T providers Internet service = 7
Number of houses Spectrum providers Internet service = [tex]35 \times \frac{2}{7}[/tex]
Number of houses Spectrum providers Internet service = 10
Total number of houses use hotspot = 35 - 7 - 10
Total number of houses use hotspot = 18 houses

Answer: D
Step-by-step explanation:
100!=2*3*4*...*100
Counting which numbers are divisible by 2:
2,4,6,8,10,12,14,...,96,98,100 : 50 numbers (100/2=50)
Counting which numbers are divisible by 4=2²:
4,8,12,16,20,...96,100: 25 numbers (100/4=25)
Counting which numbers are divisible by 8=2³:
8,16,24,32,40,...,96: 12 numbers (100/8=12.5 ==> 12)
Counting which numbers are divisible by 16=2⁴:
16,32,48,...,96: 6 numbers (100/16=6.25 ==> 6)
Counting which numbers are divisible by 32=2⁵:
32,64,96 : 3 numbers(100/32=3.125 ==>3)
Counting which numbers are divisible by 64=2⁶:
64 : 1 number (100/64=1.5625 ==>1)
Sum of those numbers= 50+25+12+6+3+1=97
100! is divisible by 2⁹⁷.

Solve for x and find the value of the unknown angle measures.
Answer:
x = 20
m = 92
n = 68
p = 92
Step-by-step explanation:
x = 20
2 + 3x = 62
-2 -2
----------------
3x = 60
----- -----
3 2
x = 20
m = 92
20 + 68 = 88
180 - 88 = 92
n = 68
The vertical angle is 68 degrees
p = 92
Vertical angle is m, which is 92.

PLS HELP THIS IS WITH THE HELP OF SQAURES
Step-by-step explanation:
you heard of the Pythagoras formula for rectangular triangles ?
c² = a² + b²
c is the Hypotenuse (the side opposite of the 90 degree angle), a and b are the other 2 sides touching the 90 degree angle.
so, in your case here we have therefore
x² = 8² + 6² = 64 + 36 = 100
x = sqrt(100) = 10
you know "sqrt" is an international abbreviation for square root : the opposite of squaring a number.
Alexandra's family took a road trip to the Grand Canyon. Alexandra slept for the last 48 miles of the trip. If the total length of the trip was 800 miles, what percentage of the total trip had they travelled when Alexandra fell asleep
Answer:
She fell asleep for 6% of the trip.
Step-by-step explanation:
You take 48 and divide it by 800. That gives you 0.06.
0.06 equals 6%.
Answer:
6%
Step-by-step explanation:
Divide 48 and 800 together.
48/800 = 0.06
48 is the miles she's sleeping and 800 is the total miles.
So, she was asleep only 6% of the trip.

Answer:
(2, - 6 )
Step-by-step explanation:
Use the mid point formula and equate to each coordinate of the midpoint
with endpoints (x₁, y₁ ) and (x₂, y₂ ) then
midpoint = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
let S = (x, y) , then
[tex]\frac{x+0}{2}[/tex] = 1 ( multiply both sides by 2 )
x = 2
and
[tex]\frac{y+2}{2}[/tex] = - 2 ( multiply both sides by 2 )
y + 2 = - 4 ( subtract 2 from both sides )
y = - 6
Then S (2, - 6 )

If 5x + 3 = 23 , what does 12x - 10 equal ?
Answer:
38
Step-by-step explanation:
5x+3 = 23
5x = 23-3
x = 20/5
x = 4
12x-10 = ?
12 (4) -10
48 -10
38
The value of the expression 12x - 10 will be 38.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that 5x + 3 = 23. To calculate the value of 12x -10 first calculate the value of x.
5x+3 = 23
5x = 23-3
x = 20/5
x = 4
Calculate the value of 12x - 10.
12x-10 = ?
12x-10 = 12 (4) -10
12x-10 = 48 -10
12x-10 = 38
Therefore, the value of the expression 12x - 10 will be 38.
