Use PEMDAS form. (Parentheses, exponents, multiplication, division, addition, subtraction.) You will first solve -2-8 which is -10, then finish with 9 + (-10), or 9-10, which is -1. The answer is -1.

Forty-seven percent of fish in a river are catfish. Imagine scooping out a simple random sample of 25 fish from the river and ob

WARRIOR [948]

Answer:

Therefore the correct option is a.) The standard deviation is 0.0998. The 10% condition is met because it is very likely there are more than 250 catfish in the river.

Step-by-step explanation:

i) Let p = 0.47

ii) therefore q = 1 - 0.47 = 0.53

iii) sample size, n =25

iii) standard deviation = $\sqrt{\frac{p \times q}{n} } = \sqrt{\frac{0.47 \times 0.53}{25} } = 0.0998$

Therefore the correct option is

a.) The standard deviation is 0.0998. The 10% condition is met because it

is very likely there are more than 250 catfish in the river.

Describe the steps you could use to graph any function.

inna [77]

Well you need to find the y-intercept (the number after the number with the x) and plot that number on the graph. next you need to find the slope (ex. 3x+4 the slope would be 3/1) and then you would plot the rest of the points using the slope. and last you would draw a line through the points.
