At what rate of simple interest will ₹4400 amount to ₹5610 in 5 years 6 months

Ilia_Sergeevich [38]

Answer:

0.05 or 5%

Step-by-step explanation:

The formula for simple interest is as follows:

A = P(1+rt), with A representing the final amount, P representing the initial amount, r being the rate, and t being time. Plugging our values in, we have

5610 = 4400(1+5.5r). We know that 5 years and 6 months is 5.5 because 6 months = 0.5 years

5610 = 4400(1+5.5r)

expand

5610 = 4400 + 24200r

subtract 4400 from both sides to isolate the variable and its coefficient

1210 = 24200r

divide both sides by 24200 to isolate the variable

r = 0.05 or 5% as 0.05 * 100 = 5

Put the following equation in slope-intercept form: y−5=7/4(x-1)

Lelu [443]

Answer:

$y - 5 = \frac{7}{4} (x - 1) \\ 4y - 20 = 7x - 7 \\ 4y = 7x + 13 \\ y = \frac{7}{4} x + \frac{13}{4}$

A sample of 8 new models of automobiles provides the following data on highway miles per gallon. Highway Miles Model Per Gallon

Furkat [3]

Answer:

The point estimate for the mean is 29.5 miles per gallon and the standard deviation is 5.9

Step-by-step explanation:

The formula por the point estimate of the mean is:

$mean(x) = \frac{x1+x2+x3+...+xn}{n}$

And for the standard deviation:

$desv(x)=(\frac{1}{n-1}sum(xi^{2} - n*x^{2} ))^{1/2}$

So for the mean:

$mean(x)=\frac{33.6+26.8+20.2+38.7+35.1+28.0+26.2+27.6 }{8} \\\\mean(x)=\frac{236.2}{8} \\\\mean(x)=29.5$

And for the standard deviation:

$desv(x)=(\frac{1}{8-1} ((33.6-29.5)^{2} +(26.8-29.5)^{2} +(20.2-29.5)^{2} +(38.7-29.5)^{2} +(35.1-29.5)^{2} +(28-29.5)^{2} +(26.2-29.5)^{2} +(27.6-29.5)^{2})^{1/2} \\\\desv(x)=(\frac{1}{8-1} ((4.1)^{2} +(-2.7)^{2} +(-9.3)^{2} +(9.2)^{2} +(5.6)^{2} +(-1.5)^{2} +(-3.3)^{2} +(-1.9)^{2})^{1/2} \\\\desv(x)=\sqrt{\frac{243.3}{7}} \\\\desv(x)=\sqrt{34.7} \\\\desv(x)=5.9$
