Answer:

Slope: 2/3 y-intercept: 1

Step-by-step explanation:

The graph crosses the y-axis at 1 and goes right 3 and up 2. slope is rise over run so it rises 2 and runs 3.

Answer: Choice C

x/w and z/(y+v)

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

Explanation:

All answer choices have that first fraction with a denominator of w. This implies that AB = w is the hypotenuse. This only applies to triangle ABD.

Focus on triangle ABD. It has an opposite leg of AD = x, when the reference angle is ABD (or angle B for short).

So we can say sin(ABD) = opposite/hypotenuse = AD/AB = x/w

x/w is one of the answers

-----------

Also note how y+v is the same for each denominator in the second fraction. y+v is the hypotenuse of triangle ABC. When the reference angle is ABD (aka angle ABC), the opposite side of this same triangle is AX = z

Therefore,

sin(ABD) = sin(ABC) = opp/hyp = AC/BC = z/(y+v)

z/(y+v) is the other answer

Side note: triangle ACD is not used at all.

Find the slope and the y-intercept of the of the linear equation.<br><br> 0=2-3y+12x

andrew11 [14]

The slope is 4 and the y-intercept is $\frac{2}{3}$

Step-by-step explanation:

The general form of a linear equation is Ax + By + C = 0, where

A is the coefficient of x
B is the coefficient of y
C is the numerical term
A, B, and C are integers
The slope of the line = $\frac{-A}{B}$
The y-intercept = $\frac{-C}{B}$

∵ The linear equation is 0 = 2 - 3y + 12x

- Switch the two sides and arrange the terms as the general

form above

∴ 12x - 3y + 3 = 0

∴ A = 12

∴ B = -3

∴ C = 2

∵ The slope of the line = $\frac{-A}{B}$

- Substitute A by 12 and B by -3

∴ The slope of the line = $\frac{-12}{-3}$

∴ The slope of the line = 4

∵ The y-intercept = $\frac{-C}{B}$

- Substitute C by 2 and B by -3

∴ The y-intercept = $\frac{-2}{-3}$

∴ The y-intercept = $\frac{2}{3}$

The slope is 4 and the y-intercept is $\frac{2}{3}$

A new cream that advertises that it can reduce wrinkles and improve skin was subject to a recent study. A sample of 70 women ove

Yanka [14]

Answer:

Yes, evidence shows that the cream will improve the skin of more than 40% of women over the age of 50 in 0.01 significance level.

Step-by-step explanation:

We need to make a hypothesis test.

Let p be the proportion of women who used cream report skin improvement.

$H_{0}$ : p=0.4

$H_{0}$ : p<0.4

To test the hypothesis, we need to calculate z-score of the sample mean and compare its probability with the significance level.

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

p(s) is the sample proportion of women reported improvement (0.5)

p is the proportion assumed under null hypothesis. (0.4)

N is the sample size (70)

Putting the numbers:

z= $\frac{0.5-0.4}{\sqrt{\frac{0.4*0.6}{70} } }$ ≈ 1.71

And P(z<1.71) ≈ 0.955. Since 0.955>0.01 we fail to reject the null hypothesis that the cream will improve the skin of more than 40% of women.
