What is the area of the right triangle shown below?

Hatshy [7]

Answer:

1.5

Step-by-step explanation:

base x height x 0.5

Pythagorean theorem: c^2 - a^2 = b^2

b = square root of (2.5)^2 - (1.5)^2

= 2

b = height

area = 0.5 x 1.5 x 2 = 1.5

Solve for x in the diagram below.

gogolik [260]

Answer:

x = 9

Step-by-step explanation:

The parallel lines divide the sides of the triangle in proportion, that is

$\frac{20-8}{x}$ = $\frac{8}{6}$

$\frac{12}{x}$ = $\frac{8}{6}$ ( cross- multiply )

8x = 72 ( divide both sides by 8 )

x = 9

Convert 6.25 to degrees

Elenna [48]

I'm going to take a guess that you are wanting to convert 6.25 radians to degrees. If I'm wrong, then ignore this! Use the fact that 1 radian = 57.2958°. Using the factor label method of conversion, we have $6.25r* \frac{57.2958deg}{1r}$ . The radian label cancels leaving us with degrees. 6.25*57.2958=358.09°

An article in a journal reports that 34% of American fathers take no responsibility for child care. A researcher claims that th

Gwar [14]

Answer:

correct option is D.0.0019

Step-by-step explanation:

given data

journal reports p = 34%

random sample n = 225

yielded = 97

solution

we get here first Sample proportion that is

Sample proportion p1 = $\frac{97}{225}$ ...............1

Sample proportion p1 = 0.4311

and here Null hypothesis is

H0 = p ≤ 0.34 ........................2

and

for Alternate hypothesis is

Ha = p > 0.34 ..........................3

so we get here z statistics that is express as

z = $\frac{p1- p}{\sqrt{\frac{p(1-p)}{n}}}$ ....................4

put here value and we get

$z = \frac{0.4311-0.34}{\sqrt{\frac{0.34(1-0.34)}{225}}}$

solve it we get

z = 2.88468

so here p-value for a test will be

P (z > 2.88468)

P = 1 - P (z < 2.88468)

P = 0.001957

so correct option is D.0.0019
