Compare the graph of Car A to the table of Car B to determine which car is traveling at the greates
speed and by how much. Show work.
Answers
Answer:
Car a is moving at 15 miles per hour
Its slope is 15/1
Its equation is y = 15x
Car b is moving at 7.5 miles per hour
Its slope is 7.5
Its equation is y = 7.5x
Car a is moving twice as fast as car b
Step-by-step explanation:
But here's how you solve
Chose 2 points and find the change in y and change in x, then divide in the same order.
Point 1: (1, 15)
Point 2: (2, 30)
Change in y = 15
Change in x = 1
y = miles
x = hours
15 miles/1 hour
You can also do this
Pick a point and just divide it's y by its x. For example:
(4, 60)
60 miles/4 hours
15 miles per hour
Now that we have the slope, we can get the equation for the graph:
y = 15x + 0
or just y = 15x, because there is no y-intercept
Now let's solve for car b:
Chose a point:
(3, 22.5)
Divide its y by its x
22.5/3
7.5
Car b is moving at 7.5 miles per hour
Now that we have the slope, we can get the equation for the graph:
y = 7.5x + 0
or just y = 7.5x, because there is no y-intercept
Compare the speeds
Car a: 15 mph
Car b 7.5 mph
15 > 7.5
So, Car a > Car b
15/7.5 = 2
So Car a moves twice as fast as Car b

A group of engineers developed a new design for a steel cable. They need to estimate the amount of weight the cable can hold. The weight limit will be reported on cable packaging. The engineers take a random sample of 44 cables and apply weights to each of them until they break. The 44 cables have a mean breaking weight of 778.1 lb. The standard deviation of the breaking weight for the sample is 15.5 lb.
Find the 99% confidence interval to estimate the mean breaking weight for this type cable.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary.
(Please show your work)
Answers
Answer:
12
Step-by-step explanation:
Since this is a right angle triangle, and we have two lengths already found, we can use pythagoras to find x.
We know that
a²+b²=c²
Where a, and b are the smaller lengths (the adjacent and opposite), and C is always the longest one (the hypotenuse).
We want to find x, which in this case is c. So,
to solve for c, we get
c=[tex]\sqrt{a^2+b^2 }[/tex]
So, after plugging in the values, we get
[tex]c=\sqrt{10.6^2+6.1^2}[/tex]
[tex]c=12.23\\\\=12 (rounded)[/tex]

If Keenan makes a basket with 6 apples, what is the ratio of apples to oranges written as a fraction?
Answers
The ratio of apples to oranges, written as a fraction If Keenan makes a basket with 6 apples, is 5 / 4.
What is a fraction?Only verbal descriptions of a portion of the whole were used to write fractions in ancient Rome. The numerator and denominator of fractions are first written in India with one number above the other but without a line. The line used to divide the numerator and the denominator were only added by Arabs.
Given:
For every 4 oranges, there are 5 apples,
Keenan makes a basket with 6 apples,
Calculate the number of oranges as shown below,
The number of oranges = 4 / 5 × 6 = 24 / 5
Calculate the fraction of apples to oranges as shown below,
Ratio = The total number of apples / The number of oranges
Ratio = 6 / 24 / 5
Ratio = 30 / 24
Ratio = 5 / 4
Thus, the ratio is 5 / 4.
