Which property can be used to expand the expression -2(3/4x+7)
geniusboy [140]

Answer:

B. <u>the distributive property</u>

Step-by-step explanation:

<u>Distributive </u><u>property</u> can be used to expand the expression -2(3/4x+7).

When that property is used, we need to distrubute the monomial to the binomial which is the two terms.

- 2( \frac{3}{4} x  + 7) \\  \Longrightarrow \boxed{- 2( \frac{3}{4} x) +  - 2(7)}

Find the area of the shaded regions:
Crank

First, we'll find the area of the large section, including the smaller section that is white.

Area of a circle: pi x r^2

A = pi x 7^2

A = 49pi x 120/360

A = 49/3 pi cm^2

Now, we'll find the area of the small section.

A = pi x 3^2

A = 9 pi x 120/360

A = 3pi cm^2

All that's left to do now is subtract.

49/3 pi - 3 pi

40/3 pi cm^2

(or 13 1/3 = 13.33 cm^2)

Hope this helps!

Home sales again In the previous exercise, you found a 95% confidence interval to estimate the average loss in home value. a) Su
Sphinxa [80]

Answer:

Step-by-step explanation:

Given that Home sales has 95% confidence interval to estimate the average loss in home value.

a) If std deviation of losses doubles as 3000 from 1500, we have margin of error also increases.  Because margin of error

= ±Critical value * Std error

= ±Critical value * Std dev/sqrt n

Hence we find that whenever std deviation increases the margin of error increases, for the same level of confidence.

b) Whenever confidence level increases, critical value increases and as a result margin of error increases.  Hence by reducing from 95% to 90% confidence interval would be reduced. True

c) Instead of changing conf level, increasing sample size would give more reliale and accurate results.
