Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = $\frac{270}{500}$ = 0.54

Confidence level = 95%

now,

standard error, SE = $\sqrt{\frac{p(1-p)}{n}$

or

SE = $\sqrt{\frac{0.54(1-0.54)}{500}$

or

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]

Will Mark Brainliest If Correct Answers! Need Some Help Please

djverab [1.8K]

Answer:

Step-by-step explanation:

a) 4x¹⁰ = 2² * x¹⁰

64x² = 2⁶ *x²

GCF = 2² * x² = 4x²

b) 4x¹⁰ - 64x² = 4x²*(x⁸ - 16)

=4x² *[ (x⁴)² - 4²]

= 4x² * (x⁴ + 4) (x⁴ - 4)

= 4x² * (x⁴ + 4)* [(x²)²- 2²]

=4x² * (x⁴ + 4) * (x² + 2)(x² - 2)
