I NEED HELP WITH OPPERATIONS WITH COMPLEX NUMBERS
(PLEASE HELP)
Answer:
see below
Step-by-step explanation:
z1 = sqrt(3) -i
z2 = -i
z1+z2 = sqrt(3) -i + -i = sqrt(3) -2i
z1-z2 = sqrt(3) -i - -i = sqrt(3) +-i +i = sqrt(3)
z1*z2 = sqrt(3) -i * -i = sqrt(3)*-i -i*-i = -sqrt(3)i + i^2 = -sqrt(3)i -1
z1/z2 = sqrt(3) -i / -i = sqrt(3)/-i - i/-i = sqrt(3) *i/-i*i +1 = sqrt(3)i/-i^2 +1
= sqrt(3) i +1

The Institute of Education Sciences measures the high school dropout rate as the percentage of 16- through 24-year-olds who are not enrolled in school and have not earned a high school credential. Last year, the high school dropout rate was 8.1%. A polling company recently took a survey of 1,000 people between the ages of 16 and 24 and found that 6.5% of them are high school dropouts. The polling company would like to determine whether the dropout rate has decreased. At a 5% significance level, the decision is to ________.
Answer:
Step-by-step explanation:
Given that:
The population proportion = 8.1% = 0.081
Sample size = 1000
The sample proportion [tex]\hat p[/tex] = 6.5% = 0.065
The null and the alternative hypothesis for these studies can be computed as:
[tex]\mathbf{H_o : p = 0.081} \\ \\ \mathbf{H_1 : p \neq 0.081}[/tex]
Since [tex]H_1[/tex] is not equal to the population proportion; then this is a two-tailed test.
The level of significance is given as 5% = 0.05
The standard error [tex]\sigma_p[/tex] of the sample proportion [tex]\hat p[/tex] can be computed as:
[tex]\sigma_p = \sqrt{\dfrac{p(1-p)}{n} }[/tex]
[tex]\sigma_p = \sqrt{\dfrac{0.081(1-0.081)}{1000} }[/tex]
[tex]\sigma_p = \sqrt{\dfrac{0.081(0.919)}{1000} }[/tex]
[tex]\sigma_p = 0.0086[/tex]
The z score test statistic is calculated as:
[tex]z =\dfrac{\hat p - p}{\sigma_p}[/tex]
[tex]z =\dfrac{0.065- 0.081}{0.0086}[/tex]
z = −1.860
For a two-tailed test, the p-value = [tex]2 \times P(Z < -|z|)[/tex]
[tex]p-value = 2 \times P(Z < - 1.86)[/tex]
p-value = 2 × 0.0314
p-value = 0.0628
Rejection Criteria: To reject [tex]H_o[/tex] ; if the p-value is less than the level of significance ∝
The decision rule: We failed to reject the null hypothesis since the p-value is greater than the level of significance ∝.
Thus, there is insufficient evidence to conclude that p is not equal to 0.081

Enter your answer as a decimal in the box.
Answer:
0.3
Step-by-step explanation:
1.9r + 0.1r = 0.6
Add like terms on the left side.
2r = 0.6
Divide both sides by 2.
r = 0.3
Answer:
3.333 continued
Step-by-step explanation:
Add 1.9r and .1r because they are like terms and you get 2r
Divide 2/.6
r = 3.3333

4x+1y=12 solve please need help
Answer:
-0.25y
Step-by-step explanation:
Simplifying
4x + 1y = 12
Solving
4x + 1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
4x + 1y + -1y = 12 + -1y
Combine like terms: 1y + -1y = 0
4x + 0 = 12 + -1y
4x = 12 + -1y
Divide each side by '4'.
x = 3 + -0.25y
Simplifying
x = 3 + -0.25y
Answer:
x = 3 + -0.25y
Step-by-step explanation: Simplifying:4x + 1y = 12Solving:4x + 1y = 12Solving for variable 'x'.:Move all terms containing x to the left, all other terms to the right.Add '-1y' to each side of the equation.4x + 1y + -1y = 12 + -1yCombine like terms: 1y + -1y = 04x + 0 = 12 + -1y4x = 12 + -1yDivide each side by '4'.x = 3 + -0.25ySimplifyingx = 3 + -0.25y16x-5=5+11x I really dont get these

the length of a rectangle is 24 feet more than the width. The perimeter of the rectangle is 88 feet. What is the length and width of this rectangle?
Answer:
W = 10 ft
Step-by-step explanation:
Represent the length by L and the width by W. Then L = W + 24.
The perimeter is P = 2W + 2L, or 88 ft. Thus, after substituting L = W + 24,
88 ft = 2W + 2(W + 24), or
88 = 2W + 2W + 48, or, after reduction,
44 = 2W + 24, or
2W = 20, and so W = 10 ft
The length of the rectangle is 34 feet.
The given parameters;
perimeter of the rectangle, P = 88 feet.let the width of the rectangle = wthen, the length of the rectangle, L = 24 + wThe length of the rectangle is calculated as follows;
P = 2(L+ w)
P = 2(24 + w + w)
P = 2(24 + 2w)
88 = 48 + 4w
subtract 48 from both sides of the equation;
88 - 48 = 4w
40 = 4w
w = 10
Now, solve for the length;
L = 24 + w
L = 24 + 10
L = 34 feet
Thus, the length of the rectangle is 34 feet.

In a New York coupon experiment, the experiment was conducted to test the effects of the face value of coupons on the likelihood of coupon redemption. Subjects were randomly assigned to 2 treatment groups. One group was offered 15-cent coupons and the other 50-cent coupons for four products. During the interviews, the respondents answered questions about which brands they used and how likely they were to cash coupons of the given face value the next time they shopped. In the preceding experiment, the dependent variable that was ________.
Answer:
The correct approach will be "the likelihood of cashing the coupon".
Step-by-step explanation:
That what's being examined as well as calculated throughout the experiment or observational study seems to be the dependent variable (almost always widely recognized as that of the responding variable). As a consequence of the modifications to something like the independent variable, that's what modifications. Whether large you are really at various ages would be an illustration of some kind of dependent variable.
