A soccer player kicks a ball towards the goal. The height of the ball follows a path modeled by the function ℎ()=−162+112. How long does it take the ball to hit the ground?
If a soccer ball is kicked straight up from the ground with an initial velocity of 32 feet per second, then it's height above the earth in feet is given by s(t)=-16t^2+32T where t
|x+7|>3
help me pleaseeee

Departmental Store Agora claims that their mean weekly sales of Aerosol were at most 2,400 packages over the past 6 months and population distribution is unknown. The manager wants to check if the sales have decreased in recent times. He obtained a random obtained sample of sales data from 61 stores and found that the sample mean is 3,593 packages with sample standard deviation 4919. At 7% significance level, using critical value approach see if the claim is true or not.
Answer:
There is enough statistical evidence to suggest that the department's claim is not true
Step-by-step explanation:
The mean weekly sales μ₀ ≤ 2,400 packages
The period over which the weekly sales were measured = Over the last 6 months
The number of stores in the sample, n = 61 stores
The sample mean, [tex]\overline x[/tex] = 3,593
The sample standard deviation, s = 4919
The significance level = 7% = 0.07
The critical value approach
The null hypothesis, H₀; μ ≤ μ₀
The alternative hypothesis, Hₐ; μ > μ₀
The test statistic is given as follows;
[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex]
We get;
[tex]t=\dfrac{3,593-2,400}{\dfrac{4,919}{\sqrt{61}}} \approx 1.894[/tex]
With df = n - 1 = 61 - 1 = 60 at 7% significant level, from a graphing calculator the critical-t, = 1.495598
The p-value at the test statistic is between 0.01 and 0.005
Given that the p-value is less than the significant level, and the test statistic is larger than the critical-t we reject the null hypothesis, that the mean weekly aerosol sale is less than 2,400 packages.
Therefore, there is sufficient statistical evidence to suggest that the departments claim is not true and the mean sales of Aerosols have increased to more than 2,400 packages

Please help What is the value of x. Look at picture.
Answer:
x = 50
Step-by-step explanation:
3x - 10 and 2(x + 10) are vertical angles and congruent , so
3x - 30 = 2(x + 10)
3x - 30 = 2x + 20 ( subtract 2x from both sides )
x - 30 = 20 ( add 30 to both sides )
x = 50

Explain how to add 5.3 + 9.079
Answer:
14.379
Step-by-step explanation:
1. Line up from left to right
2. Make sure that the decimals are lined up
3. Add the thousandths and hundredths with 0
4. Add 3 in the tenths place
5. Add up 9 and 5 to make 14
*IF YOU DID THE STEPS RIGHT, THEN YOU SHOULD HAVE 14.379 AS YOUR ANSWER*
Answer:
9.079
+5.300
_______
14.379
Step-by-step explanation:
Just line the decimals up and add zeros for 5.3 to 5.300 because you can't do 9.079
+5.3 because your decimal will be in the wrong spot and your answer will come out wrong
If A is the reference angle, which side is the opposite?
AB
BC
AC
Explain your thinking.
Answer:
BC
Step-by-step explanation:
it would be BC because you are basically taking the angle and drawing an arrow to the opposite side. another trick would be choosing an answer choice without the letter in it. also you didn't put what shape so I assumed it was a triangle
Helpmeeeeeeeeeeeeeeeeeeeeeeee
Answer:
B)
Step-by-step explanation:
distances:
AB = 6
BC = √4+25 = √29
CD = √0+144 = 12
AD = √5²+4² = √41
The basketball game lasted 1 hour and 40 minutes. If the game started at 7:30 p.m., what time did it end?
(Answer:_:__)
Answer:
9:10pm
Step-by-step explanation:
the game ended at 9:10pm
Answer:
21:10 (24-hour clock) or 9:10 ( 12-hour clock)
Step-by-step explanation:
Two ways it can be solved:
Starting time: 7:30
Game lasted- 1 hour and 40 minutes
Ending time-?
7:30 is converted to 24 hrs timing clock:∴ hr I min
7 : 30 pm
+ 12 : 00
___________
= 19 : 30
Then, hr I min
19 : 30
+ 1 : 40
______________
= 20 : 70
+ 1 : - 60
______________
= 21 : 10
So it ended at 21:10 (24-hour clock) or 9:10 ( 12-hour clock).
or you can just add up :hr I min
7 : 30pm
+ 1 : 40
________
= 8 : 70
+ 1 : - 60
_________
= 9 : 10 pm
