umka21 [38]

Answer:

The answer is "(25.32, 30.68)"

Step-by-step explanation:

Given:

\bar x = 28\\\\ \sigma = 4\\\\n =26\\\\

When 98\% confidence level so, the z:

\alpha = 1 - 98\% = 1 - 0.98 = 0.2\\\\\frac{\alpha}{2} =\frac{0.02}{2} = 0.01\\\\Z_{\frac{\alpha}{2}} = Z_{0.01} = 1.645\ \ \  ( Using \ z \ table )\\\\

E = Z_{\frac{\alpha}{2} \times ( \frac{\sigma}{\sqrt{n}})  

= 1.645 \times (\frac{4}{\sqrt{26}})\\\\=2.68

When  98% confidence interval estimate of the population mean  is,

\bar x - E < \mu < \bar x + E\\\\28 - 2.68 <  \mu < 28 + 2.68\\\\25.32 <  \mu < 30.68\\\\(25.32,  30.68)\\\\

A 20 foot ladder rests against a building 15 feet from the floor. How far does the ladder extend from the base of the wall? What
Sedbober [7]
Recognise firstly that you're making a right-angled triangle, with the hypotenuse being the ladder; and the wall and ground making up the other two sides. One vertical side is 15 ft long, the hypotenuse is 20 ft long. Use Pythagoras' Theorem to solve for the length of the remaining side: <span><span>a2</span>+<span>b2</span>=<span>c2</span></span><span><span>152</span>+<span>b2</span>=<span>202</span></span><span><span>b2</span>=400−225</span><span><span>b2</span>=175</span><span>b=<span>175<span>−−−</span>√</span>=13.22ft</span> To get the angle the ladder makes to the ground, use the trigonometric functions - sine in this case: <span>sinθ=<span><span>opposite</span><span>hypotenuse</span></span></span><span>sinθ=<span>1520</span></span><span>θ=si<span>n<span>−1</span></span>(0.75)</span><span><span>θ=0.848radians(48.5degrees)</span></span>

A suit sells for one hundred thirty-eight dollars. A store employee bought the suit, using his employee discount of forty-five p
Rzqust [24]

Answer:

$62.10

Step-by-step explanation:

To calculate how much the employee's discount actually was, we just multiply the original price by the discount

Plug the prices in --> 138 x 45/100

Simplify 45/100 --> 9/20

138/1 x 9/20 = 1242/20

1242/20 = 62.1

62.1 = $62.10

and thus, the discount is $62.10
