ILL GIVE BRAINLIEST IM ON A TIME CRUNCH PLEASE HELP!!!!! What is the solution to the system of equations below? y = negative thr

Vesnalui [34]

Answer:

The system of equations as described:

y = (-3/4)x + 3

y = -12

Combining two equations, we have:

=> -12 = (-3/4)x + 3

=> -15 = (-3/4)x

=> x = -15 x (-4/3) = 20

=> Solution is (20, -12)

=> Option A is correct.

Hope this helps!

A data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66

blondinia [14]

Answer:

The 99% confidence intervals are

(98.4346 , 98.7654)

C) This suggests that the mean body temperature could very possibly be 98.6degrees°F.

Step-by-step explanation:

Given data a data set includes 106 body temperatures of healthy adult humans having a mean of 98.7degreesF and a standard deviation of 0.66degreesF

sample size n = 106

Mean of the population ' μ' = 98.7degreesF

standard deviation of population 'σ' = 0.66degreesF

Mean of the sample x⁻ = 98.6degreesF

Level of significance ∝ = 0.99 0r 0.01

Confidence limits :-

The values $(x^{-} - 2.58\frac{S.D}{\sqrt{n} } ,x^{-} +2.58\frac{S.D}{\sqrt{n} } )$ are called 99% of confidence limits

For the mean of the Population corresponding to the given sample.

$(98.6 - 2.58\frac{0.66}{\sqrt{106} } ,98.6 +2.58\frac{0.66}{\sqrt{106} } )$

on calculation, we get

(98.6 - 0.1654,98.6 + 0.1654)

The 99% confidence intervals are

(98.4346 , 98.7654)

C) This suggests that the mean body temperature could very possibly be 98.6degrees°F.

A new car is purchased for 23900 dollars. The value of the car depreciates at 9.75% per year. To the nearest year, how long will

inna [77]

Answer:

11 years

Step-by-step explanation:

we know that

The formula to calculate the depreciated value is equal to

$V=P(1-r)^{x}$

where

V is the depreciated value

P is the original value

r is the rate of depreciation in decimal

x is Number of Time Periods

in this problem we have

$P=\$23,900\\r=9.75\%=0.0975\\x=?\\V=\$7,700$

substitute in the formula

$7,700=23,900(1-0.0975)^{x}$

$(77/239)=(0.9025)^{x}$

Apply log both sides

$log(77/239)=xlog(0.9025)$

$x=log(77/239)/log(0.9025)$

$x=11\ years$
