we know that

A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant

so

Let

a1=24 \ a2=24.48\ a3=24.97\ a4=25.47

\frac{a2}{a1} = \frac{24.48}{24}= 1.02

a2=a1*1.02

\frac{a3}{a2} = \frac{24.97}{24.48}= 1.02

a3=a2*1.02

\frac{a4}{a3} = \frac{25.47}{24.97}= 1.02

a4=a3*1.02

therefore

The common ratio is equal to 1.02

<u>the answer is</u>

Answer:

The common ratio is 1.02

Step-by-step explanation:

An arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is called the common difference. A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called the common ratio.

From data the differences between two consecutive terms are:

24.48 - 24 = 0.48

24.97 - 24.48 = 0.49

25.47 - 24.97 = 0.5

Then, there is no common difference and the sequence is not arithmetic.

From data the ratio between two consecutive terms terms are:

24.48/24 = 1.02

24.97/24.48 = 1.02

25.47/24.97 = 1.02

Then, the common ratio is 1.02 and the sequence is a geometric one.

what are the domain and range of f(x) = 4x – 8? domain: {x | x is a real number}; range: {y | y &gt; –8} domain: {x | x is a rea
Serga [27]

Answer : domain: {x | x is a real number}; range: {y | y >- 8}

the domain and range of f(x) = 4^x – 8

For exponential function , there is no restriction for x

So domain is all real numbers

For exponential function , f(x) = a^x + b

The range is y > b

The range of f(x) = 4^x -8 is y> -8

domain: {x | x is a real number}; range: {y | y > –8}

A heap of rubbish in the shape of a cube is being compacted into a smaller cube. Given that the volume decreases at a rate of 3
inna [77]

Answer:

-1/4 meter per minute

Step-by-step explanation:

Since, the volume of a cube,

V=r^3

Where, r is the edge of the cube,

Differentiating with respect to t ( time )

\frac{dV}{dt}=3r^2\frac{dr}{dt}

Given, \frac{dV}{dt}=-3\text{ cubic meters per minute}

Also, V = 8 ⇒ r = ∛8 = 2,

By substituting the values,

-3=3(2)^2 \frac{dr}{dt}

-3=12\frac{dr}{dt}

\implies \frac{dr}{dt}=-\frac{3}{12}=-\frac{1}{4}

Hence, the rate of change of an edge is -1/4 meter per minute.

The Ignorance Survey: United Kingdom A survey was conducted in the United Kingdom, where respondents were asked if they had a un
lukranit [14]

Answer:

Here we have given two catogaries as degree holder and non degree holder.

So here we have to test the hypothesis that,

H0 : p1 = p2 Vs H1 : p1 not= p2

where p1 is population proportion of degree holder.

p2 is population proportion of non degree holder.

Assume alpha = level of significance = 5% = 0.05

The test is two tailed.

Here test statistic follows standard normal distribution.

The test statistic is,

Z = (p1^ - p2^) / SE

where SE = sqrt[(p^*q^)/n1 + (p^*q^)/n2]

p1^ = x1/n1

p2^ = x2/n2

p^ = (x1+x2) / (n1+n2)

This we can done in TI_83 calculator.

steps :

STAT --> TESTS --> 6:2-PropZTest --> ENTER --> Input all the values --> select alternative "not= P2" --> ENTER --> Calculate --> ENTER

Test statistic Z = 1.60

P-value = 0.1090

P-value > alpha

Fail to reject H0 or accept H0 at 5% level of significance.

Conclusion : There is not sufficient evidence to say that  the percent of correct answers is significantly different between degree holders and non-degree holders.

A bridge is rated to a capacity of 100 British tons. What is the maximum weight the bridge can support in kilograms? (Round to t
S_A_V [24]

Maximum weight the bridge can support in kilograms is 101696

Step-by-step explanation:

  • Step 1: Given capacity of bridge = 100 British tons. Find how many kilograms are equivalent to 1 British ton.

1 British ton = 2240 pounds

1 pound = 0.454 kg

⇒ 1 British ton = 2240 × 0.454 kg = 1016.96 kg

  • Step 2: Find how many kilograms are in 100 British tons.

⇒ 100 × 1016.96 = 101696
