Answer:

(B) (x-2)

Step-by-step explanation:

The given equation is:

x^2-9x+14

Factorizing the above equation, we get

=x^2-7x-2x+14

=x(x-7)-2(x-7)

=(x-2)(x-7)

which is the required simplified factorized form.

Thus, (x-2) is the correct factor from the given options.

Therefore, option (B) is correct.

On a factory floor, 30 out of every 140 toy robots is defective. What percent is defective?
yaroslaw [1]

Answer:

21.43\%

Step-by-step explanation:

we know that

To find out the percent of robots which are defective, divided the number of defective robots by the total number of robots and multiply the result by 100

Let

x ----> the number of defective robots

y ----> the total number of robots

p ---> percentage of robots which are defective

so

p=\frac{x}{y} (100)

we have

x=30\\y=140

substitute

p=\frac{30}{140}(100)

p=21.43\%

Assume the population of human body temperatures has a mean of 98.6 degrees Fahrenheit as is commonly believed. Assume the stand
Dennis_Churaev [7]

The probability that the mean of a sample of 106 randomly selected humans is lower than 98.5°F is 4.85%

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Z score is given as:

z = (raw score - mean) ÷ (standard deviation/√sample size)

Given mean of 98.6°F,  standard deviation is 0.62°F, sample size = 106

For x < 98.5:

z = (98.5 - 98.6) ÷ (0.62÷√106) = -1.66

P(z < -1.66) = 0.0485

The probability that the mean of a sample of 106 randomly selected humans is lower than 98.5°F is 4.85%
