Answer:

180° - 1/2(α + β)

Step-by-step explanation:

The two angles of the triangle ADB are:

m∠A/2 and m∠B/2 or
α/2 and β/2

The three interior angles add to 180°, so the missing angle is:

m∠ADB = 180° - 1/2(α + β)

Pre-Algebra

Distributive Property

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define

(6x² - 4x + 2) - (-2x² + 3x - 5)

Step 2: Simplify

Distribute negative: 6x² - 4x + 2 + 2x² - 3x + 5
Combine like terms (x²): 8x² - 4x + 2 - 3x + 5
Combine like terms (x): 8x² - 7x + 2 + 5
Combine like terms (Z): 8x² - 7x + 7

Researchers wondered if there was a difference between males and females in regard to some common annoyances. They asked a rando

Zinaida [17]

Answer:

Step-by-step explanation:

Males proportion $p_1 = \frac{163}{532} =0.3064$

Females proportion $p_2 = \frac{203}{589} =0.3447$

$H_0: p_1 = p_2\\H_a: p_1$

(one tailed test for comparison of proportions)

Test statistic = $\frac{p_1-p_2}{p(1-p)\sqrt{\frac{1}{n_1}+\frac{1}{n_2} } }$

=-1.3641

Here p= combined proportion = $\frac{163+203}{532+589} \\=0.3291$

p value = 0.0869

Since p >0.05, accept null hypothesis.

The evidence does not suggest a higher proportion of females are annoyed by this behavior

Which is the better deal?

aliina [53]

Answer:

36 oz

Step-by-step explanation:

Get the other options down to 12oz units for their price and then you can compare which one is the cheapest for 12oz.

12oz = $1.99

36oz/3 = 12oz so $2.59/3 = $ .86

48oz/4= 12oz so $3.99/4 = $1.00

60oz/5= 12oz so $4.59/5 = $ .92

So looking at the breakdown, the 36oz one is the cheapest because for that price for a third of it comes out to .86 cents.
