What is the solution to 3/2b + 5 &lt; 17? Explain How.
jek_recluse [69]
<h3>3/2b + 5 < 17</h3>

<em>We subtract 5 from both sides of the inequality.</em>

<h3>3/2b + 5 - 5 < 17 - 5</h3><h3>3/2 b < 12</h3>

<em>Multiply both sides by 2/3.</em>

<h3>( 2/3) * (3/2b) < (2/3) * 12</h3><h3>b < 8</h3>

<em>Therefore, the </em><em>correct option</em><em> is </em><em>alternative "A".</em>

<em>We would think that it is </em><em>option B,</em><em> but the only difference is that it changes the</em><em> direction of the sign.</em>

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.

figure

Opposite = 35

Angle = 45 degrees

Required

Hypotenuse  = x

USing the theorem

Sin 45 = 35/x
x = 35/sin45

x = 35√2

Hence the value of x from the figure is 35√2
