ANSWER:

[8] By intersecting secant theorem,

  • x + 27 = 9 + 21
  • x + 27 = 30
  • x = 30 – 27
  • x = 3

[9] By intersecting secant theorem,

  • 7x + 2 + 18 = 6x + 3 + 20
  • 7x + 20 = 6x + 23
  • 7x – 6x = 23 – 20
  • x = 3

[10] By secant property,

  • x + 7 = 13 + 8
  • x + 7 = 21
  • x = 21 – 7
  • x = 14

Suppose that 20% of the residents in a certain state support an increase in the property tax. An opinion poll will randomly samp
zepelin [54]

Answer:

C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.

Step-by-step explanation:

Given that 20% of the residents in a certain state support an increase in the property tax.

Sample size = 400

We want the sample proportion to be within 0.04 of the true proportion (i.e., between 0.16 and 0.24)

i.e. margin of error <0.04

Std error of sample = \sqrt{\frac{pq}{n} } =\sqrt{\frac{0.2(0.8)}{400} } \\=0.02

Critical value = margin of error/ std error = \frac{0.04}{0.02} \\=2

We know z value for 95% two tailed roughly equals 2.

Hence 95% confidence is right.

C) There is roughly a 95% chance that the resulting sample proportion will be within 0.04 of the true proportion.

Popcorn kernels pop independently (i.e. unimolecularly). For one brand at constant temperature, 12 kernels pop in 5 seconds when
likoan [24]

Answer:

no of kernels  pop = 4.34

Step-by-step explanation:

given data

kernels pop in 5 second  = 12

kernels are present = 235

solution

we get here kernels are pop at rate of here

kernels are pop at rate = 12  ÷  235  

kernels are pop at rate = 0.051063

and

we get here maximum kernels are remaining that is

maximum kernels remaining = 235 - 140

maximum kernels remaining = 85

so

no of kernels  pop in 5 second will be

no of kernels  pop = 0.051063   × 85

no of kernels  pop = 4.34
