Answer: $\text{Slope}=\Large\boxed{Unde fined}$

Step-by-step explanation:

Given information

$(x_1,~y_1)=(-8,~-1)$

$(x_2,~y_2)=(-8,~11)$

Given the formula for the slope

$\text{Slope}=\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute values into the formula

$\text{Slope}=\dfrac{(11)-(-1)}{(-8)-(-8)}$

Simplify the numerator and the denominator

$\text{Slope}=\dfrac{11+1}{-8+8}$

$\text{Slope}=\dfrac{12}{0}$

Simplify the fraction

$\text{Since any number divided by 0 is impossible to find, therefore: }$

$\text{Slope}=\Large\boxed{Unde fined}$

Hope this helps!! :)

Use this formula:
$P(t) = P_0 (1 + r)^t$
$P(12 years) = (96000) \cdot (1.04)^{12}$
$P(12) = 153699$

Based on historical data, your manager believes that 41% of the company's orders come from first-time customers. A random sample

TEA [102]

Answer:

The probability that the sample proportion is between 0.35 and 0.5 is 0.7895

Step-by-step explanation:

To calculate the probability that the sample proportion is between 0.35 and 0.5 we need to know the z-scores of the sample proportions 0.35 and 0.5.

z-score of the sample proportion is calculated as

z= $\frac{p(s)-p}{\sqrt{\frac{p*(1-p)}{N} } }$ where

p(s) is the sample proportion of first time customers
p is the proportion of first time customers based on historical data

N is the sample size

For the sample proportion 0.35:

z(0.35)= $\frac{0,35-0.41}{\sqrt{\frac{0.41*0.59}{72} } }$ ≈ -1.035

For the sample proportion 0.5:

z(0.5)= $\frac{0,5-0.41}{\sqrt{\frac{0.41*0.59}{72} } }$ ≈ 1.553

The probabilities for z of being smaller than these z-scores are:

P(z<z(0.35))= 0.1503

P(z<z(0.5))= 0.9398

Then the probability that the sample proportion is between 0.35 and 0.5 is

P(z(0.35)<z<z(0.5))= 0.9398 - 0.1503 =0.7895

If A = 50 degrees, B = 62 degrees, and a = 4, find b. Round to the nearest tenth.

Phoenix [80]

<h3>Answer: 4.6</h3>

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

Work Shown:

Use the law of sines

b/sin(B) = a/sin(A)

b/sin(62) = 4/sin(50)

b = sin(62)*4/sin(50)

b = 4.61042489526572

b = 4.6

Make sure your calculator is in degree mode.
