Answer:

$7.85

Step-by-step explanation:

To solve this problem, we can use the cancelling of units.

cost = $3.14/1 lb * 2.5 lb

The pounds cancel out leaving dollars so you get cost = $3.14 * 2.5

so cost = $7.85.

A recent survey based on a random sample of n=470 voters, predicted that independent candidate for the mayoral election will get
julsineya [31]

I have an expression

\sigma = \sqrt{p(1-p)/n}

floating around in my head; let's see if it makes sense.

The variance of binary valued random variable b that comes up 1 with probability p (so has mean p) is

E( (b-p)^2 ) =  (-p)^2(1-p) + (1-p)^2p = p(1-p)

That's for an individual sample. For the observed average we divide by n, and for the standard deviation we take the square root:

\sigma = \sqrt{p(1-p)/n}

Plugging in the numbers,

\sigma = \sqrt{.24(1-.24)/490} = 0.019 = 1.9\%

One standard deviation of the average is almost 2% so a 27% outcome was 3/1.9 = 1.6 standard deviations from the mean, corresponding to a two sided probability of a bit bigger than 10% of happening by chance.

So this is borderline suspect; most surveys will include a two sigma margin of error, say plus or minus 4 percent here, and the results were within those bounds.

Someone help me please
Zinaida [17]

Step 1. Isolate the variable x:

3x-11 > 7x+9

-4x > 20

x > -5

Step 2. Use the simplified inequality to graph:

  1. Select an OPEN point on x = -5
  2. Select a ray extending from -5 to positive infinity (GREATER than -5)

I hope this helps!

Find the value of x<br> A. 11.67°<br> B. 42.5°<br> C.18°<br> D.20°
Julli [10]

Answer:

D. 20°

Step-by-step explanation:

The entire angle = 90 degrees you can tell that from the corner indicator

Set the two expressions equal to 90

(3x+10) + (x) = 90

Combine like terms

4x + 10 = 90

Subtract 10 from both sides to cancel it out

4x = 80

Divide each side by 4

x = 20

Check it by substituting x for 20

3(20) + 10 = 70     x = 20     70 + 20 = 90

Founder's Park is planning to add a slide. The scaled model gives the reduced measures. A slide has a width of 3.5 inches and he
OLEGan [10]

Answer: The slide will have a height of <u>6</u> feet.

Step-by-step explanation:

Given: A slide has a width of 3.5 inches and height of 3 inches.

For required slide , width = 7 feet]

To keep the slide proportional to the model,

\dfrac{\text{height of the required slide}}{\text{height of the slide }}=\dfrac{\text{width of required slide}}{\text{width of slide}}

\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=\dfrac{7}{3.5}\\\\\Rightarrow\ \dfrac{\text{height of the required slide}}{3}=2\\\\\Rightarrow\ \text{height of the required slide}=3\times2 =6\ \text{feet}

hence, the slide will have a height of <u>6</u> feet.
