Answer:
The 96th term of the given AP is (-1048)
Step-by-step explanation:
We have, the given AP is :
-3, -14, -25....
First term is -3
Common difference is -14 - (-3)= -11
Let [tex]a_{96}[/tex] is the 96th term of the AP.
The nth term of the AP is given by :
[tex]a_n=a+(n-1)d[/tex]
Put all the values, such that,
[tex]a_{96}=(-3)+(96-1)\times (-11)\\\\a_{96}=-1048[/tex]
So, the 96th term of the given AP is (-1048).

HELP ME ASAP PLS ! Marianne’s box for camp measures 24 inches by 24 inches by 14 inches. Will her field hockey stick , which is 1 yard long , fit in the box ? Explain your answer
Answer:
Yes
Step-by-step explanation:
24²+24²=x², x = 33.94
33.94²+14²=x², x = 36.71 inches
1 yard is about 36 inches, so it should just fit.
5 + x = -2
I need work and answer!!!!
We need to get x by itself.
We do that by subtracting 5 from both sides.
This leaves us with x = -7.
So x = -7 is the solution.
Answer:
The final answer is [tex]x = -7[/tex] .
Step-by-step explanation:
Solve the equation:
[tex]5 + x = -2[/tex]
Subtract both sides by 5:
[tex]5 - 5 + x = -2 -5[/tex]
[tex]x = -7[/tex]
So, therefore, [tex]x = -7[/tex] is the final answer.

The solution is, the 30th term of the sequence a_30 = 96.
What is Arithmetic progression?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.
The nth term of AP : a_n = a + (n – 1) × d
here, we have,
the given sequence is,
-20,-16, -12,-8,-4, ...
so, here, we have,
a = -20
d = 4
so, the 30th term of the sequence is,
a_30 = a + (30-1) d
= -20 + 29*4
= 96
Hence, The solution is, the 30th term of the sequence a_30 = 96.

Super Strength Inc. has found that the relationship between their sales and their net profit can be described by a polynomial function G(x) in which x is their sales (in thousands of dollars) and G(x) is their net profit (in thousands of dollars). What would be an appropriate domain for this function?
Answer:
x ≥ 0
Step-by-step explanation:
The domain of the profit function G(x) is the set of all possible values that "x" could assume. In this function, "x"represents the sales in thousand of dollars, therefore the minimum possible value is zero (scenario in which there are no sales). Assuming an hypothetical scenario in which the company has an infinite supply capacity, there is no upper limit for what their sales might be. Thus, the domain for the function is x ≥ 0.
Answer:
x > or equal to 0

Bartolo is running a race. He determines that if he runs at an average speed of 15 feet/second, he can finish the race in 6 seconds. If he runs at an average speed of 18 feet/second, he can finish the race in 5 seconds. Which equation represents this inverse variation?
Answer:
The Equation that represents these inverse variation is:
Speed is inversely proportional to Time
Speed (S) ∝ 1/ Time(T)
And the constant of proportionality = Distance(D)
Therefore, Speed = Distance/ Time
Step-by-step explanation:
For an inverse variation, one element increases while the other element decreases. In this question, the element or variable that increases is the speed while the element or variable that decreases is the time.
We can see from the question that
a) If he runs at an average speed of 15 feet/second, he can finish the race in 6 seconds.
b) If he runs at an average speed of 18 feet/second, he can finish the race in 5 seconds
Speed is inversely proportional to Time because the higher the speed, the lesser the time it takes to go or move in a particular direction or to go in a particular distance.
Hence, the Equation that represents these inverse variation is:
Speed is inversely proportional to Time
Speed (S) ∝ 1/ Time(T)
For inverse variation or proportionality, a constant is always needed
And the constant of variation or proportionality = Distance(D)
Therefore, Speed = Distance/ Time

Answer: C) H0 : μ = 250 , Ha: μ < 250
Step-by-step explanation:
The questions is incomplete. The correct question is
A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g. Let u be the mean weight of the burritos at this restaurant and ĉ be the mean weight of the burritos in the sample. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:
A) H0 : x = 250 , Ha : x < 250
B) H0 : x = 250 , Ha : x > 250
C) H0 : μ = 250 , Ha: μ < 250
C) H0 : μ = 250 , Ha: μ > 250
Solution:
The null hypothesis is the hypothesis that is assumed to be true. The restaurant advertises that its burritos weigh 250. This is the null hypothesis. 250 is the population mean,μ . Thus, the null hypothesis is
H0 : μ = 250
The alternative hypothesis is what the researcher expects or predicts. The consumer advocacy group tests if the mean weight is significantly lower than 250g. This is the alternative hypothesis. It is expressed as
H0 : μ < 250

Yes, because 0.002 < 0.01

Answer:
a = -1/2 & k = 3/7
Step-by-step explanation:
Solve for a over the real numbers:
24 a^3 + 8 a^2 + 6 a + 4 = 0
The left hand side factors into a product with three terms:
2 (2 a + 1) (6 a^2 - a + 2) = 0
Divide both sides by 2:
(2 a + 1) (6 a^2 - a + 2) = 0
Split into two equations:
2 a + 1 = 0 or 6 a^2 - a + 2 = 0
Subtract 1 from both sides:
2 a = -1 or 6 a^2 - a + 2 = 0
Divide both sides by 2:
a = -1/2 or 6 a^2 - a + 2 = 0
Divide both sides by 6:
a = -1/2 or a^2 - a/6 + 1/3 = 0
Subtract 1/3 from both sides:
a = -1/2 or a^2 - a/6 = -1/3
Add 1/144 to both sides:
a = -1/2 or a^2 - a/6 + 1/144 = -47/144
Write the left hand side as a square:
a = -1/2 or (a - 1/12)^2 = -47/144
(a - 1/12)^2 = -47/144 has no solution since for all a on the real line, (a - 1/12)^2 >=0 and -47/144<0:
Answer: a = -1/2

Solve for k over the real numbers:
(7 k - 3) (k^2 - 2 k + 7) = 0
Split into two equations:
7 k - 3 = 0 or k^2 - 2 k + 7 = 0
Add 3 to both sides:
7 k = 3 or k^2 - 2 k + 7 = 0
Divide both sides by 7:
k = 3/7 or k^2 - 2 k + 7 = 0
Subtract 7 from both sides:
k = 3/7 or k^2 - 2 k = -7
Add 1 to both sides:
k = 3/7 or k^2 - 2 k + 1 = -6
Write the left hand side as a square:
k = 3/7 or (k - 1)^2 = -6
(k - 1)^2 = -6 has no solution since for all k on the real line, (k - 1)^2 >=0 and -6<0:
Answer: k = 3/7
If 80% of an item is $144.00, what is the original price?
Answer:
180
Step-by-step explanation:
Answer:
180
Step-by-step explanation:
the original price * 80% = 144
Change to decimal form
the original price * .80 = 144
Divide each side by .80
the original price * .80/.80 = 144/.80
the original price =180

Step-by-step explanation:
Move all terms not containing y to the right side of the equation.
4y=22+6
Then add 22 and 6.
4y=28
Divide each term in 4y=28 by 4
4y÷4=28÷4
Cancel the common factor of 4 in the first part of the equation so it looks like this...
y=28÷4
Divide 28 by 4.

There are 7 red 3 green 2 blue and 8 purple marbles in a bag if a marble is randomly chosen 250 times predict how many times it should be red or green
Answer:
It should be red or green 125 times
Step-by-step explanation:
The first thing to do here is to calculate the probability of selecting a red or a green marble
Total number of marbles = 7 + 3 + 2 + 8 = 20
Probability of selecting a red marble is 7/20
Probability of selecting a green marble is 3/20
The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2
Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times
