A set of tires is designed to last 6 years, with a standard deviation of 2 years. What is the probability that a tire will last
evablogger [386]

Answer:

16%.

Step-by-step explanation:

We may assume that the times are normally distributed.

We first find the z-score which is the (value - mean) / standard deviation.

z-score =  (4 - 6)/2 = -1.

Looking up the value for -1 on a z-score normal distribution table we find that -1 gives us 0.1587  - that is 16%.

Which binomial is a factor of 49x2 + 84 xy + 36y2?
bezimeni [28]

Answer:

(7x+6y) is a binomial factor of the given expression  49x^2+84xy+36y^2

Therefore  49x^2+84xy+36y^2=(7x+6y)(7x+6y)

Step-by-step explanation:

Given expression is 49x^2+84xy+36y^2

To find the binomial factor :

49x^2+84xy+36y^2

Rewritting the above expression as

=7^2x^2+2(7)(6)xy+6^2y^2

=(7x)^2+2(7x)(6y)+(6y)^2

=(7x+6y)^2 ( using the formula =(a+b)^2=a^2+2ab+b^2 here a=7x and y=6y )

=(7x+6y)(7x+6y) ( using the formula =(a+b)^2=(a+b)(a+b) )

Therefore  49x^2+84xy+36y^2=(7x+6y)(7x+6y)

(7x+6y) is a binomial factor of the given expression  49x^2+84xy+36y^2
