Find the area and perimeter of fig ABCD where B=90 and angle DAC=90 degrees. AB=6cm and BC=8cm and DA=24cm

STALIN [3.7K]

Answer:

$96\ \text{cm}^2$

$17.1\ \text{cm}$

Step-by-step explanation:

$DC$ is the length of the hypotenuse of the triangle $CED$ .

$DC=\sqrt{ED^2+EC^2}\\\Rightarrow DC=\sqrt{16^2+6^2}\\\Rightarrow DC=17.1\ \text{cm}$

The perimeter of the $ABCD$ is $17.1\ \text{cm}$

$AB+AD+DC+CB=6+24+17.1+8=55.1\ \text{cm}$

The Area of $ABCD$ would be

Area of rectangle ABEC+Area of triangle CED

$8\times 6+\dfrac{1}{2}\times 16\times 6=96\ \text{cm}^2$

The area of the figure $ABCD$ is $96\ \text{cm}^2$ .

A credit reporting agency claims that the mean credit card debt in a town is greater than $3500. A random sample of the credit c

Lera25 [3.4K]

Answer:

Claim is false

Step-by-step explanation:

Claim : A credit reporting agency claims that the mean credit card debt in a town is greater than $3500.

$H_0:\mu \leq 3500\\H_a:\mu = 3500$

n = 20

Since n <30

So we will use t test

Formula : $t =\frac{x-\mu}{\frac{s}{\sqrt{n}}}$

s = standard deviation = 391

x = 3600

n = 20

$t =\frac{3600-3500}{\frac{391}{\sqrt{20}}}$

$t =1.14$

Degree of freedom = n-1 = 20-1 = 19

α=0.10

So, using t table

$t_({\frac{\alpha}{2},d.f.})$ = 1.72

t critical > t calculated

So we accept the null hypothesis

Hence we reject the claim that the mean credit card debt in a town is greater than $3500.
