Which of these numbers is irrational?
Without multiplying, tell whether the product 0.644 x 0.25 will be greater than 1 or less than 1? Explain how you know. Then find the product.
Answer:
0.161 which is less than one
Step-by-step explanation:
Pretty simple just 0.644 × 0.25 = 0.16100
But you can take off the zeros and it is less than 1 because it is 0.161 not 1.16

Equation of the sinusoidal function
f(x) = 2sin(6x) - 7
What is sinusoidal function?A sinusoidal function is one with a smooth, repetitive oscillation. "Sinusoidal" comes from "sine", because the sine function is a smooth, repetitive oscillation.
Examples of everyday things which can be represented by sinusoidal functions are a swinging pendulum, a bouncing spring, or a vibrating guitar string.
Given,
Graph of a sinusoidal function intersects its midline at (0, -7) and then has a minimum point at (π/4, -9)
Let function be
f(x)=asin(bx)+c ---------(1)
When x = 0
f(0)=-7,
⇒ -7=asin(0)+c
⇒ c=-7.
When x = π/4
f(π/4)=-9,
⇒ -9=asin(bx)-7;
Sine is constrained to [-1,1], and since (π/4,-9) is a minimum,
sin(bx) must be equal to -1.
⇒ -9=a·(-1) - 7
⇒ a = 2
For minimum
-1=sin(π/4.b),
⇒ πb/4=3π/2,
⇒ b=6
Putting value of a, b, c in equation (1)
f(x) = 2sin(6x) - 7
Hence, f(x) = 2sin(6x) - 7 is the equation for sinusoidal function.

g you are playing a game in which you flip 3 fair coins. it costs $1 to play the game, which must be subtracted from your winnings. Calculate the expected value for the game. If all coins show the same (all heads or all tails) you win $7, otherwise you lose your $1. The expected value of the game is
Answer:
Expected value of the game is $1.75
Step-by-step explanation:
The probability of getting a head or a tail on flipping a coin is 1/2 and so the probability of winning is 1/2 as we need all heads or all tails . There are 3 fair coins so the expected value of winning is given by =
P(1st coin =x =head)= 1/2
P(2nd coin =x =head)= 1/2
P(3rd coin =x =head)= 1/2
P(1st coin =x =tail)= 1/2
P(2nd coin =x =tail)= 1/2
P(3rd coin =x =tail)= 1/2
E(X= win) = ∑xP(x)= (1/2)³+(1/2)³= 1/8 + 1/8= 2/8
Expected value of winning the game is $ 7*2/8= 14/8=$ 1.75
$ 1.75- $1= $ 0.75
$ 0.75 (8) = $ 6
This means that for a total of $ 8 he gets $ 6.
If a bus traveled 120 miles in 2 hours, what was the average speed of the bus in miles per hour?
Answer:
60
Step-by-step explanation:
if you divide 120(the total distance traveled) by 2(the hours that it traveled) you get 60.
the answer is 60miles/1 hour or 60mph.
explanation:
so the bus completed 120miles in 2 hours. and they want you to find the speed or miles per hour the bus traveled. all you need to do is divide 120/2= 60 so the answer would be 60 miles per hour or 60mph. you know its right because the ratio of 120:2 shows how much per 2 hours we need to divide to find out how the ratio of miles:1 hours (which is better thought of as mph= miles per each hour) to show how much for 1 you divide both sides of 120:2 by 2. so 120÷2=60 : 2÷2=1 so you found the ratio is 60 miles per hour. 60:1 i hope that helps you guys out and that i didnt confuse you more.

A scientist was curious if they could predict the height of an adult man based on their father's height. They took a large sample of men and recorded each of their heights along with their fathers' heights (in centimeters). The scientist noticed a positive linear relationship between the heights. Here is computer output from a least-squares regression analysis on the sample:
Answer:
176cm
Step-by-step explanation:
ŷ = 100.640 + 0.431x
ŷ = 100.640 + 0.431(175cm)
ŷ = 100.640 + 75.425

Converting Percents to Decimals
Match the percent on the left with the decimal equivalent on the right.
4%
0.37
37%
1.80
400%

0.04
180%
0.09
Answer:
Step-by-step explanation:
To convert percents to decimals, remove the percent and move the decimal point 2 to the left.
4 % = [tex]\frac{4}{100}= 0.40[/tex]
37% = 0.37
400% = 4.00 = 4
9% = 0.09
180% = 1.80

Miguel wants to repair his home. He places a 15-foot ladder up against his home 9 feet from the base of the house. How far up the house does the ladder reach?
Answer:
12 feet
Step-by-step explanation:
i always forget abt this thing but its important to remember the pythagorean theorm is a thing. the whole a^2 + b^2 = c^2 thing. at first i looked back at sohcahtoa but thats for an angle lol. sooooooo, knowing that the hypotenuse is the ladder and the ground is the base and seeing that we need to find a since b is the base and c is the hypotenuse, we should rearrange the equation so that we can find a so now it should look like this: c^2 - b^2 = a^2. then we plug in our numbers to get this: 15^2 - 9^2 = a^2. next we would square the 15 and 9 so now our equation looks like this: 225 - 81 = a^2. now we subtract so we have: 144 = a^2. then we should find the square root of each. the square root of a^2 is a and the square root of 144 is 12 so now we have the answer: a = 12. i hope that makes sense.

8.Suppose that the seriesPcn has radius of convergence 5 and the seriesPdn has radius of convergence 8. What is the radius of convergence of the seriesP(cn dn)xn
Answer and Step-by-step explanation:
Solution:
Suppose the series:
Ʃcnxn
has the radius of convergence 5,
and the series:
Ʃdnxn
has the radius of convergence 8.
find the radius of convergence of series:
Ʃ ( cn + dn) xn = Ʃcnxn + Ʃdnxn
The radius of convergence of the cn series falls within the radius of dn, series.
So, both will converges for at least |x| < 5.
If we say, x = 5.5, then we get the sum of divergent series plus a convergent series, for which overall result is divergent.
For example:
∞ + a constant, gives result in ∞.
The radius of convergence is the minimum radius for which both series converges,
Which is 5.
Hence, R = 5.

If a jar of coins contains 20 half-dollars and 200 quarters, what is the monetary value of the coins?
Answer:
40(.50) + 200(.25) = 20 + 50 = $70
Step-by-step explanation:
40(.50) + 200(.25) = 20 + 50 = $70
Answer:
$60
Step-by-step explanation:
20 half dollars means that there's 10 dollars in it (because you divide 20 by 2 since 2 half dollars make one dollar)
It takes 4 quarters to make one dollar and if there's 200 quarters then there's 50 dollars in it (200 divided by 4 is 50)
