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.
What is an equation for the line that passes through the coordinates (-1,2) and (7,6)?
Answer: 1/2x+5/2
The slope equation Y=Mx+B
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
ŷ = 176.065

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.
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

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)

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.

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

What proportion of these kids should we expect to be nearsighted (p-hat)?
Answer:
about 21 kids out of 170 are expected to be nearsighted (20:170)
Step-by-step explanation:
we find 12% out of 70 by muliplying 170 x 0.12 which equals 20.4
However it has to round up because we cant have half a child so 21 children.
