Answer:
-15
Step-by-step explanation:
-7p+10p-16=6p+36-7
3p-16=6p+29
3p-6p=29+16
-3p=45
p=45/-3
p=-15
Answer:
Step-by-step explanation:
x² - 2x + y² - 4y - 4 = 0
x² - 2x + y² - 4y = 4
complete the squares
(x² - 2x + x₀) + (y² - 4y + y₀) = 4
the unknown number will be the square of half of the x¹ coefficient
(x² - 2x + 1) + (y² - 4y + 4) = 4 + 1 + 4
(x - 1)² + (y - 2)² = 9
This tells us that the circle is centered on (1, 2)
Which is also a point on the diameter
2x - y + a = 0
a = y - 2x
a = 2 - 2(1)
a = 0
Answer: x=4,-4 Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula
Answer:
No, does not differ.
Step-by-step explanation:
Given that there are two intersections route 7 and route 62.
At the intersection of Route 7 and North Shrewsbury in Clarendon, Vermont, 154 vehicles were observed to encounter a yellow light in the indecision zone, and 21 of them ran the red light. At the intersection of Route 62 and Paine Turnpike in Berlin, Vermont, 183 vehicles entered the intersection in the indecision zone, and 20 ran the red light.
Let p1 be the first proportion and p2 the second
We want to test whether these two proportions differ
(two tailed test at 5% significance level)
test statistic = 
Z statistic = 
p value = 0.4473
Since p >0.05 accept null hypothesis.
There is no significant difference and the proportion of redlight runners does not differ between the two intersections
Drivers who text spend about 10% of their driving time outside their own driving lane. True
<h3>Briefing:</h3>
It is accurate to say that 10% of the time texting while driving is spent in the incorrect lane. Driving while texting is extremely risky because it diverts the driver's attention from the road, making it impossible for him to see. According to research, 60% of people use cell phones while driving, making texting while driving a serious issue.
<u>Using a phone while driving raises the likelihood of an accident.</u>
Texting or using a phone in any other way has regularly been connected by researchers to higher risk. Talking on a telephone while driving has been linked to an increased crash risk in certain studies, but not all.
One of the major causes of many traffic collisions is using a cell phone while driving. Due to how distracting cell phone use is to a person's attention and mental focus, it is illegal to use a cell phone while driving in many nations.
