Find the initial amount a and the decay factor b in the exponential function y=5.05^x

kvasek [131]

Answer:

$a = 5$

$b = .05$

Step-by-step explanation:

Given

$y = 5\ .05^x$

Required

Determine a and b

An exponential function is represented as:

$y =ab^x$

By comparing: $y =ab^x$ with $y = 5\ .05^x$

$a = 5$

$b = .05$

The heights (measured in inches) of men aged 20 to 29 follow approximately the normal distribution with a standard deviation of

juin [17]

Answer:

I 90%(μ)= [69.648;71.951]

Step-by-step explanation:

The confidence interval formula is:

I (1-alpha) (μ)= mean+- [(Z(alpha/2))* σ/sqr(n)]

alpha= is the proposition of the distribution tails that are outside the confidence interval. In this case, 10% because 100-90%

Z(5%)= is the critical value of the standardized normal distribution. In this case is 1.645

σ= standard deviation. In this case 2.8 inches

mean= 70.8 inches

n= number of observations

Then, the confidence interval (90%):

I 90%(μ)= 70.8+- [1.645*(2.8/sqr(16))

I 90%(μ)= 70.8+- [1.1515)

I 90%(μ)= [70.8-1.1515;70.8+1.1515]

I 90%(μ)= [69.6485;71.9515]

I 90%(μ)= [69.648;71.951]

The equation shows the relationship between x and y:

wlad13 [49]

Answer: -7

Step-by-step explanation:

The equation is in slope-intercept form (y=mx+b), where m is the slope and b is the y-intercept

Therefore, the m value is -7 and it is the slope
