the equation y = 73x + 146.53, where x represents the number of traffic tickets and y represents the cost of car insurance, determine the cost of car insurance if you had 9 tickets.
Answer:
803.53
Step-by-step explanation:
Cost of car insurance = 73 traffic tickets + 146.53
y = (73 × 9) + 146.53
y = 657 + 146.53
y = 803.53
Car insurance costs 803.53
If Paul's average speed is 5 km per hour, how long would it take Paul to
walk 6.25 km?
Here, we are required to determine how long would it take Paul to walk 6.25 km.
The Time, t = 1.25hours (i.e 1 hour and 15mins)
Since Paul's average speed is 5km per hour = 5km/h
Speed is defined as the distance covered(in this case, km) per unit time(in this case, hours)
Therefore, Speed = Distance/Time.
Therefore, 5km/h = 6.25km/Time.
Therefore, the time taken for Paul to walk 6.25 km is ;
Time = (6.25/5)hours
Time, t = 1.25hours (i.e 1 hour and 15mins)

This table gives points on a line. What is the equation of the line?
Answer:
y = -2x + 5
Step-by-step explanation:
Assuming this is linear, the slope would be constant. For every 1 x, y decreases by 2. This means that the slope is -2.
y = -2x + b
Now all we need is the y-intercept.
If we plug in the first point (1,3), we get:
3 = -2*1+b
3 = -2+b
b = 5
This is the y-intercept.
y = -2x + 5

Find the length of dm in the given fig.
Answer:
[tex]DM=12[/tex]
Step-by-step explanation:
(Let the point where the altitude from [tex]D[/tex] intersects [tex]AB[/tex] be called as point [tex]E[/tex].) First, let's find the area of parallelogram [tex]ABCD[/tex]. The area of a parallelogram is simply [tex]b*h=bh[/tex], where [tex]b[/tex] is the parallelogram's base and [tex]h[/tex] is the parallelogram's height. If we let [tex]AB[/tex] and [tex]DE[/tex] be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram [tex]ABCD[/tex] will be [tex]AB*DE=15*8=120[/tex].
Now, how does this information matter, you might ask? Well, we can take either [tex]AB[/tex] or [tex]CB[/tex] to be the base and either [tex]DE[/tex] or [tex]DM[/tex] to be the height. In this case, let's take the latter two options, as we are looking to find the length of [tex]DM[/tex].
Therefore, we know that the area of parallelogram [tex]ABCD[/tex] can also be found by calculating [tex]CB*DM[/tex]. Since we know the values of the area and [tex]CB[/tex], we can write the following equation to solve for [tex]DM[/tex]:
[tex]Area = CB*DM[/tex]
[tex]120=10*DM[/tex] (Substitute [tex]Area=120[/tex] and [tex]CB=10[/tex] into the equation)
[tex]\frac{120}{10}=\frac{10*DM}{10}[/tex] (Divide both sides of the equation by [tex]10[/tex] to get rid of [tex]DM[/tex]'s coefficient)
[tex]12=DM[/tex] (Simplify)
[tex]DM=12[/tex] (Symmetric Property of Equality)

In 2004, the highest space plane flight was made by Brian Binnie in Space Sip One. A flight with this altitude can be modeled by the function h = -0.17t^2 + 187t + 61000, where h is the altitude in meters and t is flight time in seconds. What was the highest altitude reached by the space plane?
Answer:
h = 11242 km
Step-by-step explanation:
A flight with this altitude can be modeled by the function :
[tex]h = -0.17t^2 + 187t + 61000[/tex] ....(1)
Where h is the altitude in meters and t is flight time in seconds.
We need to find the highest altitude reached by the space plane.
Put [tex]\dfrac{dh}{dt}=0[/tex]
So,
[tex]\dfrac{d(-0.17t^2 + 187t + 61000)}{dt}=0\\\\-0.34t+187=0\\\\0.34t=187\\\\t=\dfrac{187}{0.34}\\\\t=550\ s[/tex]
At t = 550 seconds the space plane reaches the highest altitude.
Put t = 550 s in equation (1).
[tex]h = -0.17(550)^2 + 187(550)+ 61000\\\\h=112425\ m\\\\h=112.42\ km[/tex]
Hence, the highest altitude reaches by the space plane is 11242 km.

Answer:
17° and 73°
Step-by-step explanation:
For two complementary angles, the sum of angles is equal to 90 degrees.
Let other angles = x
First angle = 5+4x ...(1)
ATQ,
5+4x+x=90 ...(2)
Equation (1) and (2) shows the equations for the given problems.
5+5x=90
5x = 85
x = 17°
Other angle = 17
First angle = 5+4x
= 5+4(17)
= 73°
So, the other two angles are 17° and 73° respectively.

At a local ice cream parlor, there are 6 different flavors of ice cream from which to select (strawberry, chocolate, vanilla, rocky road, mint chocolate chip, and peanut butter). Each ice cream sundae must include 2 different flavors of ice cream; what is the probability that the next customer's sundae will have vanilla and chocolate (in either order)
Answer:
1/30
Step-by-step explanation:
let, vanilla be the first ice cream.
hence, the probability of choosing vanila= 1/6
let, chocolate be the second ice cream.
hence, the probability of choosing chocolate=1/5
hence, the probability that the next customer's sundae will have vanilla and chocolate (in either order)= (1/6)×(1/5)
=1/30

Traffic engineers studied the traffic patterns of two busy intersections on opposite sides of town at peak rush hour. At the first intersection, the average number of cars waiting to turn left was 17 with a standard deviation of 4 cars. At the second intersection, there was an average of 25 cars waiting to turn left with a standard deviation of 7 cars. The report combined the mean number of cars waiting to turn left at both intersections. Assuming the data are independent, the standard deviation of the sum is:
Answer:
The standard deviation of the sum is of 8.06.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Sum of normal variables:
When we add two normal variables, the mean is the sum of their means, and the standard deviation is the square root of the sum of their variances. In this question:
First intersection -> Standard deviation of 4
Second intersection -> Standard deviation of 7
Sum:
[tex]\sigma = \sqrt{4^2 + 7^2} = \sqrt{65} = 8.06[/tex]
The standard deviation of the sum is of 8.06.
