Answer:

y=-2x-4

Step-by-step explanation:

So remember this y=mx+b

The M is the slope and the B is our y-intercept

So according to the picture it gave you the slope and the Y-intercept

The slope was -2 and the y-intercept was -4

So y=mx+b so subtitute the m to -2 and the b to -4

The equation should be y=-2x-4

I really hope this make sense

Select all that are undefined. sec (45°) csc (0°) sec (90°)

Murrr4er [49]

Answer:

csc (0°) and sec (90°) are not defined.

Step-by-step explanation:

Given the options wehave to select the option which is undefinesd

First option: sec 45°

$sec45^{\circ}=\frac{1}{cos(45^{\circ})}=\frac{1}{\frac{1}{\sqrt2}}=\sqrt2$

which is defined

Second option: csc(0°)

$csc(0^{\circ})=\frac{1}{sin0}=\frac{1}{0}=\infty$

which is not defined

Third option: sec(90°)

$sec(90^{\circ})=\frac{1}{cos(90)}=\frac{1}{0}=\infty$

which is not defined.

Hence, option 2 and 3 are not defined.

7. Of 101 randomly selected adults

DanielleElmas [232]

Answer:

The 95% confidence interval for the true percentage of all adults over 30 who shop at that mall who admit to having lost their car at the mall is (25.37%, 43.93%).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the z-score that has a p-value of $1 - \frac{\alpha}{2}$ .

Of 101 randomly selected adults over 30 who frequent a very large mall, 35 admitted to having lost their car at the mall.

This means that $n = 101, \pi = \frac{35}{101} = 0.3465$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a p-value of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3465 - 1.96\sqrt{\frac{0.3465*0.6535}{101}} = 0.2537$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3465 + 1.96\sqrt{\frac{0.3465*0.6535}{101}} = 0.4393$

As percentages:

0.2537*100% = 25.37%

0.4393*100% = 43.93%

The 95% confidence interval for the true percentage of all adults over 30 who shop at that mall who admit to having lost their car at the mall is (25.37%, 43.93%).

Think of a number, divide it by 5 and then add 27 to the result. The resulting number is half of the original number. What was t

Salsk061 [2.6K]

This Is One Answer, There Are More Then One Answer.

100 / 5 = 20 + 27 = 47 / 2 = 23.5

100 = my number
5 = divide by

100 / 5 = 20
27 = add
20 = results of last answer
Then 20 + 27 = 47
47 = results of last answer
2 = half of
Then 47 / 2 = 23.5
