What is b?<br> − ( 3 − 6b ) = 6b + 5
zubka84 [21]

Answer:

-1 1/2

Step-by-step explanation:

-(3-6b)=6b + 5 .remember to balance!!!!

-6b + 6b= 6b + 6b

-3=12b+5

-3+5=5-5

-8=12b   now divide since its the inverse operation

think 12/-8= -1 1/2

so B equals - 1 1/2

Determine if the equations are parallel, perpendicular, or neither.
Aloiza [94]
To easily find the slope from standard form (Ax + By = C) use -A/B

1. m = -5/3
2. m = -3/5

perpendicular slopes are negative reciprocals, which these are not

parallel slopes are exactly the same, which these are also not

so, these equations are neither parallel nor perpendicular

Fred and Ted are interested in the average height of NC State students. They randomly sample students from NC State and construc
Nataly [62]

Answer:

a. Fred's margin of error is larger than Ted's.

Step-by-step explanation:

Margin of error of a confidence interval:

M = z\frac{\sigma}{\sqrt{n}}

In which z is related to the confidence level(the higher the confidence level the larger the value of z) \sigma is the standard deviation of the population and n is the size of the sample.

From this, we have that:

A higher confidence level leads to a larger margin of error.

A larger sample size leads to a smaller margin of error.

In this question:

Same confidence level.

Fred's sample is smaller, so his margin of error will be larger.

The correct answer is given by option a.

Represent 0.533 (only the last 3 is bar number) into a rational number
weqwewe [10]

Answer:

\frac{8}{15}

Step-by-step explanation:

We require 2 equations with the repeating 3 placed after the decimal point.

let x = 0.5333.. ( multiply both sides by 10 and 100 )

10x = 5.333... → (1)

100x = 53.333... → (2)

Subtract (1) from (2) tus eliminating the repeating 3

90x = 48 ( divide both sides by 90 )

x = \frac{48}{90} = \frac{8}{15}
