\sf Hello!

• \sf Base = 10\: ft
• \sf Height = 13\: ft

\sf Here,
\sf We\: only\: require \: Base\: and\: Height\: only.

\sf Area \: of\: Triangle :

= \dfrac{\sf 1}{\sf 2} × \sf Base × \sf Height

= \dfrac{\sf 1}{\sf 2} × \sf 10 × \sf 13

= \sf 5 × 13\: ft^{2} = \sf 65\: ft^{2}

\sf Hence,
\sf Area\: of\: the\: Triangle \: is\: 65\: ft^{2}

In the chart of the triangle it shows that the variable b is the base. It also give us the equation for area 1/2bh (half of base * height)

Now we just plug in the values we are given

1/2bh

1/2(10*13)

1/2(130)

65

The area of the triangle is 65 ft

soldier1979 [14.2K]

Answer:

Yes, result is significant ; PVALUE < α

Step-by-step explanation:

Given :

x = 536

n = sample size = 1012

Phat = x / n = 536 / 1012 = 0.5296 = 0.53

H0 : P0 = 0.5

H1 : P0 > 0.5

Test statistic :

(Phat - P0) ÷ sqrt[(P0(1 - P0)) / n]

1-P0 = 1 - 0.5 = 0.5

(0.53 - 0.5) ÷ sqrt[(0.5*0.5)/1012]

0.03 ÷ 0.0157173

= 1.9087

Pvalue :

Using the Pvalue from test statistic :

Pvalue = 0.02815

To test if result is significant :

α = 0.05

0.02815 < 0.05

Pvalue < α ; Hence, result is significant at α=0.05; Hence, we reject H0.

What is the volume of the cylinder below use formula v=ñr2 h
Vikki [24]

Answer:

The volume of the cylinder = π r² h

where r is the radius of the cylinder and h is the height of the cylinder.

This is formula is applied for the right cylinder as figure 1 and oblique cylinder as figure2.

<u>The volume of the cylinder of figure 1:</u>

r = 6  and  h = 7

volume = π r² h = π  * 6² * 7 = 252π   units³

<u>The volume of the cylinder of figure 2:</u>

r = 11  and  h = 15

volume = π r² h = π  * 11² * 15 = 1,815π   units³

A painter is placing a ladder to reach the third story window, which is 12 feet above the ground and makes an angle of 80 degree
mash [69]
We know that
tan ∅=opposite side angle ∅/adjacent side angle ∅
adjacent side angle ∅=opposite side angle/tan ∅

in this problem
see the attached figure to better understand the problem
angle ∅=80°
opposite side angle ∅=12 ft  (AB)
adjacent side angle ∅=? (AC)
adjacent side angle ∅=12/tan 80°------> 2.12 ft

the answer is
2.12 ft

Explain why receiving a 15% discount is the same as finding 85% percent of the original cost of an item. Then, explain how the m
Lisa [10]

Answer:

15% discount means you're paying 85% of the marked price because total is 100% and 100-15 = 85%

Let X be the naked price

Paid = marked price - discount

Paid = X - (15/100 × X)

Using distribution property,

Paid = X(1 - 15/100)

Paid = X[(100-15)/100]

Paid = X(85/100)

Which is 85/100 × X

Hence 85% of X
