The sum of two numbers is 54. The smaller number is 14 less than the larger number. What are the numbers?
Larger number:
Smaller number:
Answer:
larger number: 34
smaller number: 20
Step-by-step explanation:
54= y+y-14
54= 2y - 14
54+14 = 2y
68 = 2y
68/2 = 2y/2
34 = y, the larger number
y - 14 = 34-14 = 20 the smaller number
In 2010 there were 2000 American lions in a conservation park in Wisconsin. The lion population is decreasing
by 8% every year. Which of the following functions models the lion population after x years?
Step-by-step explanation:
After each year, the new population of the lions is 100% - 8% = 92% of the population of the lions the year before.
Hence our exponential base should be 0.92, indicating exponential decay. (A)
Answer:
after each year the new population of the lions
is 100% - 8% is equals to 92% of the population of the lion year before
Hence our exponential base should be 0.92 (A)
Which pair of binomials gives a product that is a perfect square trinomial?

The answer is (2x + 3)(2x + 3). (C)
A bottling company produces bottles that hold 10 ounces of liquid. Periodically, the company gets complaints that their bottles are not holding enough liquid. To test this claim, the bottling company randomly samples 64 bottles and finds the average amount of liquid held by the bottles is 9.9145 ounces with a standard deviation of 0.40 ounce. Suppose the p-value of this test is 0.0436. State the proper conclusion. choose from below and explain why.
A) At α = 0.05, reject the null hypothesis.
B) At α = 0.10, fail to reject the null hypothesis.
C) At α = 0.025, reject the null hypothesis.
D) At α = 0.05, accept the null hypothesis.
Answer:
A) At α = 0.05, reject the null hypothesis.
Step-by-step explanation:
Given a p-test value of 0.0436 ;
P-value = 0.0436
Recall :
Decision region :
Reject Null if p value < α
Testing the options :
A) At α = 0.05,
0.0436 < 0.05 (true)
Since p value < α ; Reject the null hypothesis.
B) At α = 0.10,
0.0436 < 0.1
True conclusion is to reject the Null Hypothesis
Hence, option B is incorrect.
C) At α = 0.025, reject the null hypothesis.
0.0436 > 0.025
True conclusion is ; Fail to reject the Null ;
Hence, option C is incorrect
D) At α = 0.05, accept the null hypothesis.
0.0436 < 0.05
True conclusion is ; reject the Null
Hence, option D is incorrect

Round 342.296269789 to 2 decimal places.
Answer:
342.29
Step-by-step explanation:
You take away the other decimal places.
The round-up to 2 decimal places of 342.296269789 will be 342.30.
How do round any digit?To round up or down of tens place then we need to look at the unit place if it is less than 5 then we need to round down and if it is greater than 5 then we need to round up of tens digit.
In order to round to a hundred, we need to look at the tens digit if it is less than 5 then we round down and if it is 5 or greater than 5 then we will round up.
For example round of 346 will, be350 and round of 344 will be 340
Given the digit,
342.296269789
Now,
The 3rd decimal digit is 6 which is greater than 5
So,
2nd digit will round up since it is 9 so it will round as 10 and gives 1 to the first decimal place.
So,
342.296269789 ⇒ 342.30.
Hence "The round-up to 2 decimal places of 342.296269789 will be 342.30".
