There is 8 sq so it's going to be a denominator. Since there is 8 sq if you take 1 away it will be 7, 7 is shaded. 1 will be the numerator.

Answer:

10.) 12 + 3i

11.) 3 - i

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y.

12.) x² - 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b±√b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

13.) x²- 8x + 17 = 0

Let's solve your equation step-by-step.

x² − 8x + 17 = 0

Step 1: Use quadratic formula with a=1, b=-8, c=17.

x= −b ± √b2−4ac / 2a

x= −(−8) ± √(−8)2−4(1)(17) / 2(1)

x= 8 ± √−4 / 2

There are no real solutions.

Step-by-step explanation:

To solve a quadratic equation by factoring,

Put all terms on one side of the equal sign, leaving zero on the other side.

Factor.

Set each factor equal to zero.

Solve each of these equations.

Check by inserting your answer in the original equation

I would guess that 4.25 pounds is another way to say 4 1/4 pounds, but without being given the answer choices, I can only give you an educated guess.

Please help with statistic 22

<h3>Answer: 0.9754</h3>

======================================================

Explanation:

p = 0.58 = probability HR rep says to follow up within two weeks

n = 7 = sample size

Let's calculate the binomial P(x) value for x = 0 which will tell us the probability of having a sample with 0 reps recommending the follow up within two weeks.

$P(x) = (_n C _x)*(p)^{x}*(1-p)^{n-x}\\\\P(0) = (_{7} C _{0})*(0.58)^{0}*(1-0.58)^{7-0}\\\\P(0) = (1)*(0.58)^{0}*(0.42)^{7}\\\\P(0) \approx 0.00230539333249 \\\\P(0) \approx 0.002 305\\\\$

If we were to randomly select a sample of n = 7 HR managers, then there's roughly a 2.305% chance that x = 0 of that group will say to follow up within two weeks. This is when there's a 58% chance of each individual rep of saying "yes".

Repeat for x = 1 and you should find that P(1) = 0.022285 approximately.

Then we can say this:

$P(\text{0 or 1})+P(\text{at least 2}) = 1\\\\P(\text{x=0 or x=1})+P(x \ge 2) = 1\\\\P(0)+P(1)+P(x \ge 2) = 1\\\\P(x \ge 2) = 1-P(0)-P(1)\\\\P(x \ge 2) \approx 1-0.002305-0.022285\\\\P(x \ge 2) \approx 0.97541\\\\P(x \ge 2) \approx 0.9754\\\\$

If we selected a sample of n = 7 HR reps, there's roughly a 97.54% chance that 2 or more reps will recommend following up within 2 weeks.
