Answer:

1. $79.38

2. It's correct.

Step-by-step explanation:

price: $105

discount: 30%

tax: 8%

Calculate 30% of 105 and subtract it from 105

To convert 30% to decimals, divide by 100.

$\frac{30}{100}=0.30$

105-0.30(105)

105-31.50

$73.50

Now calculate 8% of it and add it.

73.50+0.08(73.50)

73.50+5.88

$79.38

The heights of women in the USA are normally distributed with a mean of 64 inches and a standard deviation of 3 inches.

Rainbow [258]

Answer:

(a) 0.2061

(b) 0.2514

Step-by-step explanation:

Let X denote the heights of women in the USA.

It is provided that X follows a normal distribution with a mean of 64 inches and a standard deviation of 3 inches.

(a)

Compute the probability that the sample mean is greater than 63 inches as follows:

$P(\bar X>63)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{63-64}{3/\sqrt{6}})\\\\=P(Z>-0.82)\\\\=P(Z$

Thus, the probability that the sample mean is greater than 63 inches is 0.2061.

(b)

Compute the probability that a randomly selected woman is taller than 66 inches as follows:

$P(X>66)=P(\frac{X-\mu}{\sigma}>\frac{66-64}{3})\\\\=P(Z>0.67)\\\\=1-P(Z$

Thus, the probability that a randomly selected woman is taller than 66 inches is 0.2514.

(c)

Compute the probability that the mean height of a random sample of 100 women is greater than 66 inches as follows:

$P(\bar X>66)=P(\frac{\bar X-\mu}{\sigma/\sqrt{n}}>\frac{66-64}{3/\sqrt{100}})\\\\=P(Z>6.67)\\\\\ =0$

Thus, the probability that the mean height of a random sample of 100 women is greater than 66 inches is 0.

The least value of the function x^2 + px + q is 3 and this occurs when x = - 2. find the values of p and q

Rasek [7]

Answer:

Hello,

p=4

q=7

Step-by-step explanation:

The vertex of the parabola is (-2,3)

Equation of the parabola is k(x+2)²+3=x²+px+q

Let's identify the coefficients:

kx²+4kx+4k+3=x²+px+q

k=1

4*1=p

4*1+3=q

Write equation in standard form y-1= -1/4(x-6)

const2013 [10]

The standard form:

$Ax+By=C$

---------------------------------------

$y-1=-\dfrac{1}{4}(x-6)$ use distributive property

$y-1=-\dfrac{1}{4}x+\dfrac{3}{2}$ multiply both sides by 8

$8y-8=-2x+4\cdot3$

$8y-8=-2x+12$ add 2x to both sides

$2x+8y-8=12$ add 8 to both sides

$\boxed{2x+8y=20}$
