Step-by-step explanation:

$BC = BE + CE...(\because B-E-C) \\ \\ \therefore \: BC = 3x - 5 + x + 1 \\ \\ \therefore \: BC = 4x - 4 \\ \\ \huge \red{ \boxed{ \therefore \: BC = 4(x - 1)}}$

Answer:

The correct option is B.

Step-by-step explanation:

The amount of money, in dollars, in a savings account after x years is given by $M(x) = 10000(1.03)^{x}$

This above equation represents that $10000 becomes M(x) after x years at a rate of interest 3% compounded in each year.

Therefore, the value in the expression 1.03 represents that there is a 3 percent increase in the savings account each year.

So, the correct option is B. (Answer)

A study found that a 95% confidence interval for the mean μ of a particular population was computed from a random sample of 1200

kotykmax [81]

Answer:

95% confidence interval for the mean μ is (6,14)

The Population mean μ lies between ( 6, 14 )

Step-by-step explanation:

Explanation:-

Given random sample 'n' = 1200

95% confidence interval for the mean μ is determined by

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

Level of significance = 95% 0r 0.05

Z₀.₀₅ = 1.96

$(x^{-} -Z_{\alpha } \frac{S.D}{\sqrt{n} } , x^{-} +Z_{\alpha } \frac{S.D}{\sqrt{n} } )$ = 10 ± 4

Mean of the small sample = 10

95% of confidence intervals are

( 10 ±4 )

( 10 -4 , 10+4)

( 6 , 14 )

95% confidence interval for the mean μ lies between ( 6, 14 )

A map of the park can be divided into a grid of 9^2 equal sections of land. It is estimated that there are 9^6 ants per section

kenny6666 [7]

Answer:

9^8

Step-by-step explanation:

The total number of ants is

(total number of sections)(ants in each section).

let x be the total number of ants.

Substitute the given values.

x = (9^2)(9^6)

x = 9^(2+6) <= exponent rule: when multiplying exponents with the same base, add the exponents.

x = 9^8
