The sequence an=an−1+2 is an arithmetic sequence

The first three terms in the sequence are (a) 8, 10, 12

<h3>How to determine the first three terms?</h3>

The sequence is given as:

an=an−1+2

Where:

a1 =8

Start by calculating a2 using:

a2=a1+2

This gives

a2=8+2 = 10

Calculate a3 using:

a3=a2+2

This gives

a3=10+2 = 12

So, we have:

a1 = 8, a2 = 10 and a3 = 12

Hence, the first three terms in the sequence are (a) 8, 10, 12

{2x + 3y = 5}{ y= 5 x -4}

Natasha_Volkova [10]

Solve the system using substitutions:

$\begin{gathered} 2x+3y=5 \\ 2x+3(5x-4)=5 \\ 2x+15x-12=5 \\ 17x=5+12 \\ 17x=17 \\ x=\frac{17}{17} \\ x=1 \end{gathered}$

x has a value of 1. Use this value to find the value of y.

$\begin{gathered} y=5x-4 \\ y=5\cdot1-4 \\ y=5-4 \\ y=1 \end{gathered}$

y has a value of 1.

x=1

A random sample of 85 group leaders, supervisors, and similar personnel revealed that a person spent an average 6.5 years on the

strojnjashka [21]

Answer:

95% of confidence interval for the Population

( 6.1386 , 6.8614)

Step-by-step explanation:

Step( i ):-

Given random sample size 'n' =85

Mean of the sample size x⁻ = 6.5 years

Standard deviation of Population = 1.7 years

Level of significance = 0.95 or 0.05

Step(ii):-

95% of confidence interval for the Population is determined by

$(x^{-} - Z_{0.05} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.05} \frac{S.D}{\sqrt{n} })$

$(6.5 - 1.96\frac{1.7}{\sqrt{85} } , 6.5 + 1.96 \frac{1.7}{\sqrt{85} })$

( 6.5 - 0.3614 , 6.5 + 0.3614 )

( 6.1386 , 6.8614)

Conclusion:-

95% of confidence interval for the Population

( 6.1386 , 6.8614)

jenyasd209 [6]

Answer:

$6 \frac{1}{14}$

Step-by-step explanation:

Write down the problem;

$2 \frac{4}{7} + 3 \frac{2}{4}$

Simplify

$2 \frac{4}{7} + 3 \frac{1}{2}$

Convert so that the fractions have a common denominator; multiply the numerator and denominator of both fractions such that the denominators are equal;

$2 \frac{8}{14} + 3 \frac{7}{14}$

Add the fractions;

$5 \frac{15}{14}$

Convert to mixed number;

$6 \frac{1}{14}$
