I'm pretty sure it is 162 inches because each yard has 3 feet in it and each foot has 12 inches, so 12*3*4.5=162

Help with this math question please

Cloud [144]

A = P( 1 + rt)
A/P = 1 + rt
A/P - 1 = rt
t = (( A/P)) - 1)/r

t = (( 5500/1000) - 1)/(6.25/100
t = (5.5 - 1)/0.0625
t = 4.5/0.0625 = 72 years

Answer it will take 72 Years...

Hope it helps!!!!!

A sample of 30 distance scores measured in yards has a mean of 7, a variance of 16, and a standard deviation of 4. You want to c

Nikolay [14]

Answer:

21, 144, 12

Step-by-step explanation:

Given that a sample of 30 distance scores measured in yards has a mean of 7, a variance of 16, and a standard deviation of 4.

Let X be the distance in yard.

i.e. each entry of x is multiplied by 3.

New mean variance std devition would be

E(3x) = $3E(x) = 21$

Var (3x) = $3^2 Var(x) = 9(16) =144$

Std dev (3x) = $\sqrt{144 } =12$

Thus we find mean and std devition get multiplied by 3, variance is multiplied by 9

Find the linear approximation for f(x) = 12x3 + 3x2 + x + 2 at x= 1.

Alchen [17]

Answer:

y = 43x − 25

Step-by-step explanation:

Evaluate the function at x=1:

f(x) = 12x³ + 3x² + x + 2

f(1) = 12 + 3 + 1 + 2

f(1) = 18

Find the slope of the tangent line at x=1:

f'(x) = 36x² + 6x + 1

f'(1) = 36 + 6 + 1

f'(1) = 43

Point-slope form:

y − y₀ = m (x − x₀)

y − 18 = 43 (x − 1)

Convert to slope-intercept form:

y − 18 = 43x − 43

y = 43x − 25
