Answer:

area = 283.39 m²

Step-by-step explanation:

r = 19/2 = 9.5

area = πr² = (3.14)(9.5²) = 283.39 m²

Area=3.14(r)^2
radius is half of diameter
3.14(9.5)^2=283.385
rounded is 283.39

The diagram shows corresponding lengths in two similar figures. Find the area of the smaller figure.
butalik [34]

The area are in the ratio of the squares of corresponding sides.

That is  15^2 : 20^2  = 225:400

so the area of the smaller figure = (225/400) * 64

= 0.5625 * 64

= 36 cm^2  (answer)

Hello from MrBillDoesMath!

Answer:

(x^4-2) (x^4 -1)


Discussion:


Let u = x^4, then

x^8 - 3x^4 + 2

= u^2 - 3u + 2

= (u -2) ( u -1)

= (x^4-2) (x^4 -1)



Thank you,

MrB

A rental agent claims that the mean monthly rent for apartments on the east side of town is less than $750. A random sample of 1
klio [65]

Answer:

Its statistically significant, that Mean monthly apartment rent in town east <  $ 750

Step-by-step explanation:

Null Hypothesis [H0] : Mean monthly apartment rent in town east = 750

Alternate Hypothesis [H1]: Mean monthly apartment rent in town east < 750

t = (x' - u) / (s / √n)

x' = sample mean = 737

u = population assumed mean = 750

s = standard deviation = 23

n = no. of units in sample

t = (737 - 750) / (23 / √18)  = -13 / 5.4212

= -2.39

t tabulated critical value : for one sided 0.05 significance level, at 17 degrees of freedom = -1.740

t calculated value, -2.39 < t tabulated critical value, - 1.740

We reject the null hypothesis, & state that its statistically significant, that Mean monthly apartment rent in town east < 750
