Need help on 6. 8th grade math
frutty [35]
Don't know about the TV problem, sorry.

For the next one (Dylan) = 14.1 inches
Use the Pythagorean Theorem a^2+b^2 = c^2
10^2 + 10^2 = c^2
100 + 100 = c^2
200 = c^2

Take the square root of both sides. The hypotenuse is equal to the square root of 200, which is 14.1 when rounded to the nearest tenth of an inch.

Hope this helps

Suppose a large shipment of telephones contained 21% defectives. If a sample of size 498 is selected, what is the probability th
grandymaker [24]

Answer:

P(-3\% < x < 3\%) = 0.901

Step-by-step explanation:

Given

p = 21\%

n = 498

Required

P(-3\% < x < 3\%)

First, we calculate the z score

z = \sqrt{p * (1 - p)/n}

z = \sqrt{21\% * (1 - 21\%)/498}

z = \sqrt{21\% * (79\%)/498}

z = \sqrt{0.1659/498}

z = \sqrt{0.000333}

z = 0.0182

So:

P(-3\% < x < 3\%) = P(-3\%/0.0182 < z

P(-3\% < x < 3\%) = P(1.648 < z

From z probability, we have:

P(-3\% < x < 3\%) = 0.901
