Mathematics

kirza4 [7]3 years ago

Answer:

z = 9

Step-by-step explanation:

JH is a perpendicular bisector of Δ IJK.

Thus the triangle is isosceles with

JK = JI , that is

7z = z + 54 ( subtract z from both sides )

6z = 54 ( divide both sides by 6 )

z = 9

A student records the repair cost for 17 randomly selected stereos. A sample mean of $52.33 and standard deviation of $21.44 are
Dafna11 [192]

Answer:

90% confidence interval is (43.25, 61.41)

Step-by-step explanation:

Given that,

n = 17

Mean, \bar{x} = 52.33

Standard deviation, \sigma = 21.44

∝ = 0.10

Now,

Confidence interval = \bar{x}  ± t_{\frac{\alpha }{2}, n-1} [\frac{\sigma}{\sqrt{n} } ]

                                 = 52.33 ± 1.7646 [ 21.44 / √17 ]

                                 = 52.33 ± 9.0791

So,

52.33 + 9.0791  = 61.4091

52.33 - 9.0791  = 43.2509

So,

90% confidence interval is (43.25, 61.41)

Also,

Lower end-point = 43.25

Upper end-point = 61.41

Your answer is right. to solve it you would move the 10 over to get 10x^2-29x+10=0. i would solve by chunking and breaking -29x into -25x and -4x. This will give us (10x^2-25x)+(-4x+10). now factor both get inside the parenthesis the same. 5x(2x-5)+-2(2x-5). Now combine the factors you took out with what is inside to get (5x-2)(2x-5)
