What is the common ratio of the geometric sequence 16, 24, 36, 54, ...?
2/3
1
8
3/2
Answer:
r = 3/2
Step-by-step explanation:
The common ratio (r) is the number that, when multiplied by the previous (n-1) term, gives the nth term of the geometric sequence ([tex]a_{n} =a_{n-1}*r[/tex]). To find the common ratio, we can take any term and divide it by its preceding term (rearrange the formula to get [tex]r=\frac{a_{n}}{a_{n-1}}[/tex]). If we take 24 and divide it by 16, we get the common ratio of 3/2 ([tex]r=\frac{24}{16}[/tex], [tex]r=\frac{3}{2}[/tex]). Hope this helps.

f(x)=-x^2-10 Find f(-4)
Answer:
We conclude that:
f(-4) = -26Step-by-step explanation:
Given
We have the function
f(x) = -x² - 10
To determine
f(-4) = ?
Calclulating f(-4)
substitute x = -4 in the function
f(x) = -x² - 10
f(-4) = -(4)² - 10
f(-4) = -16 - 10
f(-4) = -26
Therefore, we conclude that:
f(-4) = -26A line is graphed below.

How do I figure out -3√12-2√27-2√45
Answer:
−12√3−6√5 or Decimal: -34.201018
Step-by-step explanation:
-3√12-2√27-2√45
3√12=6√3
2√27=6√3
2√45=6√5
=6√3-6√3-6√5

Discounts and what is the outcome
Answer:
with discount+tax= $23.15
Step-by-step explanation:
board game is 25
discount: 15%
tax: 7.5%
discount means you take off that amount
tax means you add that amount
discount: 15% off
tax: +7.5%
to find 15% of 25 multiply 25 by 15% (15/100=0.15)
25*0.15
= 3.75
then subtract that from 25
25-3.75
=21.25
tax:
0.075*25
=1.875
~1.9
21.25+1.9
=23.15
State if the two triangles are congruent. If they are, state how you know.
Answer:
1) Not Congruent
2) Congruent
3) Congruent
4) Congruent
5) Not Congruent
6) Congruent
(I tried my best, hope this helps. Good luck hun)
Step-by-step explanation:
When two triangles are congruent they will have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Each algorithm is applied to a group of 52 sample problems. The new algorithm completes the sample problems with a mean time of 24.04 hours. The current algorithm completes the sample problems with a mean time of 24.52 hours. The standard deviation is found to be 5.769 hours for the new algorithm, and 5.556 hours for the current algorithm. Conduct a hypothesis test at the 0.05 level of significance of the claim that the new algorithm has a lower mean completion time than the current algorithm.
Answer:
Therefore we fail to reject the Null hypothesis [tex]H_0[/tex]
Because the is no sufficient evidence to support the claim of the alternative hypothesis [tex]H_a[/tex]
Step-by-step explanation:
From the question we are told that
Sample size [tex]n_1 =52[/tex]
Mean time 1 [tex]\=x_1=24.04\ hours[/tex]
Mean time 2 [tex]\=x_2=24.52\ hours[/tex]
Standard deviation [tex]\partial _1=5.769[/tex]
Standard deviation [tex]\partial _2=5.556[/tex]
Level of significance 0.05
The null hypothesis is [tex]H_o: \mu_1=\mu_2[/tex]
Alternative hypothesis [tex]H_a: \mu_1<\mu_2[/tex]
Generally the test statistics is mathematically represented as
[tex]Z= \frac{\=x_1-\=x_2}{\sqrt{\frac{\sigma_1^2}{n_1}+\frac{\sigma_2^2}{n_2}}}[/tex]
[tex]Z= \frac{24.04-24.52}{\sqrt{\frac{5.769^2}{52}+\frac{5.5562^2}{52}}}[/tex]
[tex]Z= -0.4321583379[/tex]
[tex]Z= -0.43[/tex]
From Table the Z-critical value at [tex]\alpha =0.05\ is\ -1.6449[/tex]
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis [tex]H_0[/tex] at [tex]\alpha = 0.05[/tex]
Therefore we fail to reject the[tex]H_0[/tex]
Because the is no sufficient evidence to support the claim of [tex]H_a[/tex]
