What is the volume of a pyramid<br> 4 cm,4 cm by 12 cm
Alenkinab [10]

<u>Answer: </u>

The volume of pyramid with dimensions 4cm , 4cm by 12cm is \bold{64 \mathrm{cm}^{3}}

<u>Solution: </u>

Volume of a pyramid can be found out by using the below formula,

\bold{v = \frac{1}{3} l w h}

where,

v is the volume of pyramid  

l is the length of pyramid

w is the width of pyramid

h is the height of pyramid

from question, given that l = 4 ; w = 4; h = 12

hence the volume of pyramid for the given dimensions is  

v = \frac{1}{3} \times 4 \times 4 \times 12

= 4 \times 4 \times 4

= 64 \mathrm{cm}^{3}                      

So the volume of pyramid is \bold{64 \mathrm{cm}^{3}}

7 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!
Elena-2011 [213]

Answer:

Option a. convergent: A

Step-by-step explanation:

a0=3/2

a1=9/8

a2=27/32

a1/a0=(9/8)/(3/2)=(9/8)*(2/3)→a1/a0=3/4

a2/a1=(27/32)/(9/8)=(27/32)*(8/9)→a2/a1=3/4

r=a1/a0=a2/a1→r=3/4

The abosute value of r= !r! = !3/4! = 3/4 = 0.75<1, the series is convergent

Given sin x=13/85 and tan x=13/84 .
olga55 [171]

ANSWER:

We know that,

  • tanΘ = sinΘ/cosΘ

cosΘ = sinΘ/tanΘ

So, cosΘ = 13/85 ÷ 13/84

  • 13/85 × 84/13
  • 84/85.

ecn 221 The sodium content of a popular sports drink is listed as 206 mg in a 32-oz bottle. Analysis of 14 bottles indicates a s
spayn [35]

Answer:

H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}

Step-by-step explanation:

We are given the following in the question:

Population mean, μ =  206 mg

Sample mean, \bar{x} = 217.5 mg

Sample size, n = 14

Sample standard deviation, s = 14.9 mg

Claim:

The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.

Thus, we design the null and the alternate hypothesis

H_{0}: \mu = 206\text{ mg}\\H_A: \mu \neq 206\text{ mg}

We use two-tailed t test to perform this hypothesis.
